Testing the Heat Hypothesis: The Relationship between Temperature and Violent Crime Rates
subject: None
description: This paper explored the relationship between temperature and behaviour. In particular the effect heat has on violent crimes. The heat hypothesis states that increased ambient temperatures can cause increased aggressive motives and behaviours. The current study was longitudinal and archival. Data was collated from four different countries: U.S., Japan, Jamaica and Finland over a period of 40 years. Data was collected from reliable online sources for: Temperature in degrees Celsius (℃), rainfall in millimetres (mm), intentional homicide rates, assault rates, rape rates and burglary rates. Rainfall and burglary were control variables. Analyses revealed a significant and positive relationship between temperature and intentional homicide, assault and rape rates. Temperature and burglary were not significantly related. Such results provide support for the heat hypothesis. The relationship between heat and violent crime should be investigated further; as the effects of global warming increase, so may violent crime rates worldwide.

source: Data In accord with Anderson et al’s., (1997) methods, data of the following crimes were collected: intentional homicide, assault, rape and burglary within a specified 40 years. This crime data was sampled from the following countries databases: U.S., Japan, Jamaica and Finland. The inclusion criteria were to include the countries which had the most available data on crime. There were no data exclusions as the current study was retrospective, meaning all data had already been collected. The 40 years analysed within each country differed depending on data availability. Crime rates were collected in the U.S. between the years 1960 and 2000. Crime rates were collected in Japan between the years 1975 and 2015. Crime rates were collected in Jamaica between the years 1970 and 2010. Crime rates were collected in Finland between the years 1976 and 2016. Therefore there would have been 160 full observations of intentional homicide, assault, rape and robbery. However, due to limited data available there were gaps in the data. For the U.S., 40 full observations of intentional homicide, assault, rape and robbery were obtained. For Japan, 23 full observations were obtained and 17 partial. For Jamaica, 11 full observations were obtained and 29 partial. For Finland, 22 full observations were obtained and 18 partial. The crime data was police reported and per 100,000 of the population, as smaller figures were easier to manage. Crime data was collected from the following reliable online resources: Bourne et al., (2015), Burns (2013), (Knoema, 2011), (Nation Master, 2003), (Statista, n.d.), (Uniform Crime Reporting, 1930), (United Nations World Surveys, 2006), (UNODC Statistics, 1997). Websites were considered reliable if they were established official government data repositories. Temperature (℃) and rainfall (mm) data were also collected. This data was obtained from an online climate data portal (Climate Change Knowledge Portal, n.d.). Rainfall was included as a control variable to…

An investigation into automatic imitation: Comparing live and video setups, the effect of prior training and the influence on affective empathy
subject: automatic imitation, empathy, imitation training, inhibition training, mirror neuron system, self-other distinction
description: If decreased Automatic Imitation(AI) improves empathetic abilities, then selfother distinction processes are probably the mediating factor between imitation and empathy. But if increased AI improves empathy, then probably imitation is at the core of the socio-cognitive functions. Until now, it was shown that decreased AI improved visual perspective taking, corticospinal empathy and self-reported empathy. Also, the studies until now focus on video AI stimuli. But to understand whether AI has a more direct relation to mimicry, I developed also live paradigm. My research questions were firstly, what effect will imitation training and inhibition training have on AI. Secondly, whether live stimuli AI will have the same effects on AI testing (inhibition versus imitation) and arousal empathy testing. Thirdly, whether the effects are transferable on arousal empathy. As expected, there was a significant decrease of AI in the video inhibition condition in comparison to the video imitation condition. Unexpectedly, a significant, but weak increase in arousal empathy was observed in the video imitation condition and not in the video inhibition group. The difference in AI and arousal empathy between the life imitation group and the life inhibition group were not significant. The results give a new perspective on the topic of AI. If the results can be reproduced by more studies, then probably imitation is more important than self-other distinction processes or maybe arousal empathy is different from other forms of empathy. Finally, the insignificant results in the life imitation versus life inhibition training indicate that there are maybe confounding factors in live AI research or that the video AI designs are more artificial than it is assumed.

source: Participants Sixty(N=60) participants were recruited in a two-by-two factorial design, and divided equally among two between-subject factors. The first factor is Stimulus, whereby AI will be measured in response hand actions performed by an experimenter sat across a table from the participant (Live) or to the actor’s pre-recorded hand-action stimuli presented on a monitor. The second factor is Training, whereby participants will undertake a brief period of imitating the actions of the live or videoed handaction stimuli (IMI) or performing the opposite actions (IMI-IN). The participants were recruited from students of the University of Lancaster. Random selection could not be used, because of practical and logistical difficulties. Hence, most of the participants were Masters students and some were PhD students. The participants were either friends and acquaintances or they had the motivation to win a 10 pounds amazon voucher. In many cases they had the motivation to participate in my study, because they also wanted me to participate in their study. Firstly, we conducted the experiments with the video paradigm (15 participants in the imitation training condition and 15 participants in the inhibition training condition) and then we conducted the experiments of the live paradigm (15 participants in the imitation training condition and 15 participants in the inhibition training condition). We use random assignment for the recruitment in the training condition, thusly, every participant was randomly assigned in either the imitation training or in the inhibition training condition. For instance, we did not conduct first 15 experiments in the imitation training condition and then 15 experiments in the inhibition training condition, but every participant was in a different training condition. Nevertheless, one possible limitation may be that we did not do the same for the stimulus condition, as we conducted first the experiments of the video condition and then the experiment…

Does the use of prompts in shared reading facilitate the quantity and quality of language in Down Syndrome children?
subject: Down syndrome, linguistic abilities, dialogic reading, prompted reading.
description: Children with Down syndrome typically present with specific linguistic and communicative difficulties. The present study aims to explore how dialogic prompted reading facilitates better quality and quantity of language production in pre-school aged Down syndrome children. Research has demonstrated how reading interventions enhance typically developing children’s linguistic qualities, yet few studies have investigated the beneficial effects of dialogic prompted reading among Down syndrome children. Eight Down syndrome and 8 typically developing children completed two shared reading tasks with their mothers. One task involved reading a book containing a series of prompted questions, the other book contained no prompts. As predicted, prompted reading resulted in the development of more complex syntax, better vocabulary production and facilitated better responses accuracy to literal and inferential concepts, in Down syndrome children. In addition, the inclusion of prompts also increased parental scaffolding techniques for both diagnostic groups. The results from this study indicate that dialogic prompted reading does improve Down syndrome children’s qualitative and quantitative linguistic abilities and promotes better communication with parents during shared reading tasks. These findings highlight the educational significance of prompted dialogic reading as a highly beneficial intervention for developing an array of linguistic qualities in children with Down syndrome.

source: Participants A total of 16 children and their mothers took part in this study. Eight children with Down syndrome (DS: 4 female, 4 male, age range = 4.58 years to 6.75 years, Mage = 5.3 years) and 8 typically developing children (TD: 2 female, 6 male, age range = 3.9 years to 6.66 years, Mage = 5.1 years). This is a secondary data analysis study and all participants were previously recruited by the principle investigator and supervisor, Kate Cain. Video recordings of all child-parent reading dyads were made and were transcribed into written from. The Departmental Ethics Committee approved this study prior to the author receiving any video or transcribed data. Stimuli In this study, mothers were given two books to read with their children, ‘Mooncake’ and ‘Skyfire’ (Asch, 2014; 2014). Parents were asked to read both books as they normally would read at home with their child. One version of each book contained a series of 12 prompts which were inserted at specific points and parents where asked read them aloud as they went through the book (based on Van Kleek et al, 2006). Between both books there were a total of 24 prompts. For each book, prompts were evenly split between 4 sub-categories: picture labelling prompts “What is that? (pointing to Bear)”, vocabulary prompts “What does ‘hollow’ mean?”, inference prompts “ Why did Bear fall asleep?”, and general knowledge prompts “What else could Bear have used to stick the spoon to the arrow?”. The aim of the prompts was to encourage communication and scaffolding interactions between mothers and children when reading together. These books where specifically selected for multiple reasons: first, they have been successfully used in previous studies investigating linguistic impairments in pre-school aged children with language difficulties (Van Kleek et al 1997; 2006; Hammet, Van Kleek & Huberty, 2003). Second, the classic story-line of each book provides opportunities for children to follow a written and pictorial narrative, e…

Sexualised Advertising through Instagram: An exploration into the effects this has on female appearance satisfaction
subject: None
description: This study explored the beliefs and opinions held by females aged 20-23 years on Instagram. It aimed to uncover possible effects that exposure to sexualised content and beauty standards could have on young female’s appearance satisfaction. Previous literature has addressed extensively how social comparisons and internalisation of beauty ideals can negatively affect females, increasing body dissatisfaction. This research aimed to expand these findings, exploring how body and facial attractiveness seen online can affect appearance satisfaction as a whole. Previous studies have determined that internalisation and social comparison are prevalent in women that compare themselves to others on Instagram. These theories along with objectification and cultivation theory are utilized to comprehend female’s perceptions of beauty and how it could be implicating them to act in a sexualised way online. The study consisted of two focus groups, each lasting approximately one hour. A convenience sample was used recruiting university students. A semi-structured interview schedule was utilised to allow for rich data to be produced. The data was categorised by using thematic analysis strategies of coding, mapping and deducing themes. The research conclusion found that women did report decreased appearance satisfaction when viewing ‘beautiful’ girls on Instagram, social comparisons was identified as more salient with peers, yet they did also report comparing themselves with reality television stars. Findings also reported that internalisation of beauty ideals was strong, they remark television and the social media for ‘normalising’ beauty standards. Lastly, participants were found to self-objectify themselves in a sexual manner more for Instagram than other social media sites.

source: This study explores the possible effects social networking site Instagram has on young females, in relation to their appearance satisfaction. Overall, it aims to add to existing literature within this field and other domains such as sociology and women’s studies, whilst also extending previous literature, as this research looks beyond body satisfaction and addresses appearance satisfaction completely. It also provides scope into understanding Instagram and the magnitude of its effects on the user, as the majority of previous literature focuses on Facebook. 3.1 Research Design Two focus groups were conducted, each lasting approximately one hour. The focus group was held in a small lecture theatre at Lancaster University in the Management School (Lecture Theatre 12). A phenomenological approach was applied as the research aims to explore a group of participant’s experiences and aims to further make sense of these experiences (Creswell, 2013). Application of focus groups was applied as it allowed for a semi-structured narrative of findings. The participants were able to express their thoughts, feelings and opinions in relation to this topic of research. A semi-structured interview type was applied as it allows for more flexibility, allows for more rapport building and these aspects can lead to richer data which enters more novel spheres (Smith & Osborn, 2003). 3.2 Sampling The overall sample consisted of 13 female students studying at Lancaster University between the ages of 20-23 years. This age was used as research has suggested that young females within these age brackets tend to be heavy Instagram users. These participants were recruited through convenience sampling, no specific recruitment criteria concerning use of social media was applied, in order to allow this variable to fall out naturally in the sample. 3.3 Research Procedures 3.3.1 Materials The participants were given an information sheet and a consent sheet at the beginning of the focus groups.

Exploring Guilt Appeals
subject: None
description: Guilt appeals are commonly used in charity advertising as a means of persuading a consumer to donate. This qualitative study uses an Indian sample to understand if there exists any differences in how they are perceived by individuals in a society that is not guilt based. Participants were exposed to 5 advertising campaigns in a focus group interview. The research also seeks to understand other factors that persuade a consumer to donate. It was found that guilt was only a supplementary factor in persuasion and factors of personal relevance and focus of action played a larger role in persuading with the sample used in this research. Guilt was effective in changing the attitude and beliefs of a consumer, but it was the factors of personal relevance and ease and convenience that were influential in changing donation intention into charitable behaviour. However, the small sample is also a limitation in generalising the responses to an entire culture.
creator: Mridhula Ravi
source: The purpose of this research was to understand the effectiveness of charity advertisements using guilt appeals in an Indian sample. Content analysis was then used to find patterns and themes in the responses of the participants. Research Design Focus Group Interviews Since the research aimed to create a narrative of the participants opinions and views, focus groups were employed. Focus groups also enable for understanding and exploring a topic in depth and understanding the nuances of the thoughts and opinions of the participants and thus understand how they respond to guilt appeals. Interviewer The primary researcher was used as the interviewer on the basis of being well versed with the material and thus the quality of establishing rapport and guiding the focus group discussion. Discussion Guide The primary aim of this research was to understand the perception of guilt appeals in charity adverts and the factors used in the adverts that contribute to donation intention. A discussion guide was formulated in line with the aim of the research and to provide a structure to the direction of the interview. Some of the questions included: ‘How do you feel when you look at this advertisement’, ‘The advertisements intend to use guilt. Do you think that was effective’ and ‘Did you feel guilty when you were exposed to the advertisements?’ (See Appendix A). However the questions were not asked in order and were chosen based on the responses chosen by the participants. Participants A focus group with 7 participants was organised. All the participants were Indian by nationality and graduate students of Lancaster University. Of the 7 participants. There were 5 males and 2 females. The only criteria for choosing the sample was that they had to have lived in India for at least 10 years or identify as an Indian national The age of the participants ranged from 20 to 25 years old. There was no difference by gender and gender was not considered as a variable in this research. Materials …

Figurative language comprehension and links to autistic traits
subject: figurative language comprehension emotions autism
description: Figurative language is used quite frequently in both speech and writing, as to express our creative and abstract thoughts. Traditionally, it was thought that metaphors are ornamental in nature, as well as they are used rarely compared to literal language. However, today’s research suggests that people use metaphors in everyday communication. Moreover, people seem to pay more attention to sentences which are emotionally evocative, rather than neutral ones. In addition, it has been extensively reported that socio-communicative skills might be related to the successful comprehension. Special populations, such as autistic individuals, often struggle with both figurative language comprehension and acknowledging properly other people’s emotions. However, no prior research has explored both different types of sentences and their content (emotional or neutral). Sixty-two participants took an online questionnaire measuring their comprehension abilities and the Autism-Spectrum Quotient (AQ) test, in order to measure their socio-communicative skills. Significant results were found for both the type of sentences, and the content. No significant effect of socio-communicative skills affecting comprehension was found. The results are discussed in terms of their theoretical and clinical importance.
creator: Anamarija Veic
source: Participants Sixty-two typically developed participants (M=31, F=31) between the ages of 18 and 62 (M= 24, SD=9.32) were got involved in the study. The majority of sample were students at Lancaster University (N=51). Participants were recruited in Lancaster (United Kingdom) via SONA or email. Twenty-nine participants were paid £5 (five British pounds) for taking part in the study. The remaining participants were not re-imbursed for their time. Only the adults (minimum age of 18) who were British English native speakers could have taken part in this study. Participants were not aware of a true aim of the study. Participants were simply told that the project is about figurative language comprehension, as to avoid any possible bias. At the end of their participation, they were informed about the details and the aims of the study. The study has been approved by the ethics committee. Apparatus and materials The participants were asked to complete an online questionnaire developed with the Qualtrics survey software. Upon recruitment, participants were sent a Qualtrics link to the survey. All participants were exposed to the same stimuli but each of them got a different randomised order. Approximately ten minutes were sufficient for participants to take part in the study. Participants could start answering the questionnaire and then finish it at another point of time if needed, as their answers were automatically saved for seven days after they opened the questionnaire on their browser. No more than 10 sentences were shown per page, as to avoid fatigue. Both literal sentences and novel metaphors used as stimuli in this project were originally structured by Cardillo, Schmidt, Kranjec, and Chatterjee (2012). Their aim was to construct a design of matched metaphoric and literal sentences as to test the role of novelty and different metaphor types involved in metaphor comprehension. The authors managed to control the next ten dimensions: dimensions: length, frequency, concrete…

Influence of an autobiographical memory recollection on moral decision making.
subject: The language effect emotional decision making guilt empathy pro-social behaviour
description: Research shows that emotional states are involved in moral reasoning and may affect people’s decision-making processes (Achar, So, Agrawal, & Duhachek, 2016). However, in recent research emotional states were shown to be easily influenced by such factors as the language type. It was found that a stimulus presented in the native language was perceived more emotionally when compared to stimuli presented in the second language (Pavlenko, 2005). This difference in emotionality was called the language effect (Puntoni, S., Langhe, & Van Osselaer, 2009). The relationship between used language (native vs. second) and emotionality level is important as it may provide potential applications in promoting beneficial decision making and consequent behaviour. Many advertising campaigns already target emotions (i.e. empathy, guilt, regret) in order to persuade people to act by their request (Lee, Andrade, Palmer, 2013). Thus the focus of this research was to analyse the relationship between emotional language processing (native vs. second language) targeting guilt, empathy levels and how they influence the consequent behaviour (i.e. helping). A multicultural sample of 126 bilingual adults, who all speak English, as a second language, completed an online questionnaire, assessing self-reported guilt, pro-social behaviour inclination, empathy and pro-social behaviour. Results showed that no significant differences were found between two language groups, indicating the lack of language effect in the present sample. Also, the results showed that high levels of self-reported guilt were significantly and positively associated with high levels of pro-social inclination and pro-social behaviour. Empathy was shown to have the same association – high levels of empathy being associated with high levels of pro-social inclination and pro-social behaviour. Lastly, further analysis found selfreported guilt as a predictor of pro-social behaviour and pro-social behaviour inclination. Overall, this …

source: Participants Participants of this study were adults, who spoke English as a second language (N= 126, 58 males, 68 females) and ranged in age from 18 to 46. Originally there were 138 participants, but 12 were excluded from further analysis due to being the native speakers of the English language and therefore not fitting the core requirement – speaking English as a second language. Also 10 participants wrote the memory in English instead of their native language, so they were diverted to the second language condition before proceeding with the analysis. The whole sample of participants was very diverse, which consisted of 25 different nationalities and 24 different native languages (see Appendix D), the top four languages being - Lithuanian (40), Spanish (14), German (13) and Polish (13). All participants signed an online consent form and answered questions about their nationality, native language, country of residence, and English language proficiency before proceeding with the questionnaire. Materials Self-reported guilt Self-reported guilt was measured by asking participants to first – recall and describe a memory in either their native or second language (i.e. English) and then to evaluate how bad they feel about their recalled actions, how guilty they feel about those actions and how much they regret them (Nelissen, 2012). All of the three questions testing self-reported guilt were assessed by 6-point forced choice Likert scale from 1 (‘Very much’) to 6 (‘Not at all’). Before the start of analyses, the scale was reverse scored from 1 (‘Not at all’) to 6 (‘Very much’) to ensure consistency with other measures. Pro-social behaviour The pro-social behaviour was measured by asking participants, how many additional questions they would be willing to answer after completing the survey. Participants were informed that they are almost done with the survey. However, it was stated, that it would be a great help to the researchers if participants could answer some addition…

Academic Resilience: Adversity and traumatic experience in an educational context at university
subject: academic resilience traumatic experience resilience nontraumatic experience stress self-esteem self-efficacy academic performance
description: Resilience is a process whereby individuals bounce back or beat the odds despite the significant threat that can jeopardise their development. Academic resilience pertains to student´s success after educational adversity and their coping behaviour in challenging circumstances. Recently academic resilience became a validated psychological construct, and the present study uses this Academic Resilience Scale (ARS) to measure students response to academic adversity in a university sample with three analysis. The primary analysis: estimated the Life Event Checklist (LEC) or traumatic experienced and academic resilience which is unresearched. The findings indicated that students´ who have experienced a traumatic life event(s) and stressful situations are showing slightly more academic resilience than those who have not experienced a traumatic life event and stressful situations. A second analysis: academic resilience in a relationship with the life event, brief resilience, self-esteem, self-efficacy, perceived stress, and academic performance. Both self-efficacy and brief resilience predicted academic resilience. Third analysis: same parameters from the second analysis was utilised but now in a relationship with traumatic experienced and displayed that traumatic students had a more tendency for brief resilience, self-efficacy, self-esteem but perceived more stress than nontraumatic student´s. These results show that the academic resilience could be used as an intervention in the educational environment to enhance student´s coping behaviour and facilitate them to adjust more effectively in challenging circumstances.

source: Participants The sample was based on an internet survey of 154 Lancaster University students from 29 different nationalities who enrolled either as an undergraduate at first year (n = 47), second year (n = 49), third year (n = 30), Master student (n = 19) or PhD student (n = 3). Subsequently, five participants were excluded because of not being a student. The final sample contained 149 participants between the ages of 18 and 52 years old (M = 21.21; SD = 3.66). Majority of participants ethnicity was 51.6% British, 10.5% Chinese, 3.3% Indian, 2,6% South Korean and 2.6% Cypriot and other nationalities were in the minority. The principal investigator was not able to obtain gender because of a technical problem. Materials Academic Resilience Scale-30 (ARS-30) ARS-30 (Cassidy, 2016), measures academic resilience and is developed to estimate university students. Participants answer 30 statements of an imaginative vignette where a comment or feedback from a tutor about a low grade on an assessment that was presented. Participants imagine themselves being in that position and their response is confined to a statement: „You have received your mark for a recent assignment, and it is a ‘fail.’ The marks for two other recent assignments were also poorer than you would want as you are aiming to get as good a degree as you can because you have clear career goals in mind and don’t want to disappoint your family. The feedback from the tutor for the assignment is quite critical, including reference to ‘lack of understanding’ and ‘poor writing and expression,’ but it also includes ways that the work could be improved. Similar comments were made by the tutors who marked your other two assignments.“ Responses were on a 5-point Likert scale 1 (very likely) to 5 (very unlikely). Items include, “ I would not accept the tutors´ feedback”; “I would just give up”; and” I would blame the tutor.” Following the guidelines provided by Cassidy (2016), 9 of the items were reverse-coded (e.g., “I w…

Experiencing social acceptance and rejection through ‘likes’ and ‘dislikes’: Does sleep quality affect the processing of social rewards?
subject: Adolescence Pupil dilation Social feedback Reward Rejection Sleep debt.
description: In adolescence, high importance is placed on peer evaluations and social rewards have increased salience during this developmental period. Sleep patterns also change in adolescence, as teenagers typically experience insufficient sleep. This research measured the pupil dilation of forty-four adolescents aged 16 to 18 using two tasks (audio and visual) to investigate whether sleep duration influenced the way social acceptance and rejection were processed. Sleep duration scores were obtained using the measure of sleep debt; this was calculated by subtracting sleep duration during the week from sleep duration at the weekend, plus weekday bedtime. It was expected that higher sleep debt would be linked to increased pupil reactivity towards social feedback and that there would be a greater pupil dilation in response to social rejection compared to social acceptance. In the visual task, it was found that sleep debt affected males and females differently when processing social rewards, as females with high sleep debt showed increased pupil dilation towards positive feedback compared to negative feedback, whereas males with low sleep debt showed a larger dilation towards positive feedback than females. It was also found that females with lower sleep debt gave more likes than dislikes when rating photos. This implies that sleep duration affects the social feedback adolescents provide. When a male voice was used in the audio task, more pupillary reactivity towards social acceptance was observed, however when a female voice was used, pupils dilated more in response to social rejection. Future research should further investigate these gender differences.

source: Participants Forty-four participants (N=44) were recruited from Haslingden High School and Sixth Form to participate in this research. The participants (35 female, 9 male) were all between the ages of 16 and 18 (Mage = 16.98, SDage = .63). Students in Psychology, Sociology and English classes were given the opportunity to participate in the research and contacted the researcher via email if they wished to participate. Each participant provided their informed consent before beginning the study. Materials Photo ratings. Firstly, the participants were shown a PowerPoint containing 40 photos, which had been previously collected by the researcher, and featured adolescents which the participants did not know. Each photo was displayed individually for four seconds, meaning that the presentation lasted two minutes and forty seconds in total. Participants were provided with a sheet of paper on which they had an option to tick either ‘like’ or ‘dislike’ for each photo on the PowerPoint (see Appendix A). The total number of likes was calculated for each participant. Eye tracker. An eye-tribe desktop eye tracker with a 30Hz sampling rate was used to measure the pupil dilation of the participants in response to stimuli on two tasks - a visual task and an audio task. A chin rest was used to ensure the participants kept their heads still. Visual task. The visual task involved showing the participants the same 40 photos which they had previously been shown in the photo rating task, however, each photo had either a ‘like’ symbol or ‘dislike’ symbol (see Figure 1) in the bottom right hand corner. Participants were informed prior to beginning the task that if a photo contained the ‘like’ symbol, it meant that the individual in the photo had liked the participant’s picture, however the ‘dislike’ symbol meant that the individual in the photo had disliked the participant’s picture. The presentation of photos was randomised across participants Audio task. The audio task involved the parti…

Interacting in a Virtual Environment, the role of visual perception, the human hand and the recognition of rescaling.
subject: Visual Perception Rescaling effects Virtual Reality Hand-size Constancy Body size effects.
description: A common assumption from perception research is that we can estimate the size of the environment by using our own hand as a perceptual metric by comparing the size of our hand to the environment. Further research aimed to explore this effect by manipulating the size of the hand to see if it could accurately estimate the size of objects and found that even when the hand was magnified or minimized people perceived their hand to stay around the same size. The effect that the hand is perceived as a constant size is called the hand-size constancy effect and the current research has aimed to expand on previous research by examining if hand-size constancy still occurs even when hand size increases whilst in the presence of the participant. This research was done using a new method which eliminates more demand characteristics than previous hand-size constancy research. Participants took part in a virtual scenario using virtual reality in which each time a participant attempted the task, their hand or non-corporeal hand gradually increased in size, until a total of 38% size increase. Results from this research found that participants did recognise their hand size increase in the non-corporeal condition and did not notice hand size change in the real hand condition. These results support previous research by finding that hand size constancy can still occur even when eliminating demand characteristics that may have occurred in previous research using a more discrete method.

source: Participants. The participants were 30 typically developing adults between the ages of 19 and 50 (N = 30, 12 male and 18 female, M = 24.39 years old, SD = 7.76 years). Participants were mainly recruited from a major university in the North West of England using posters on the university campus and online advertisements. Participants received £5 in return for their participation. Materials The current research used the Oculus Rift with leap motion to detect hand movement. The experiment was created using the Unity game engine software to create a programme called the virtual bowling alley. The virtual bowling alley was created to mimic a real table top bowling alley in which all the items in the game were created for this experiment including the bowling ball, the pins and the virtual hand used in the experiment. Two questionnaires were essential to this study, “The Embodiment Questionnaire” and “The Virtual Presence Questionnaire”. The Embodiment questionnaire was an adaptation from Sanchez-Vives’ research which explored visual hand illusions (Sanchez-Vives, Spanlang, Frisoli, Bergamasco, & Slater, 2010). The embodiment questionnaire was used to test the extent of different variables the participant may exhibit whilst within virtual reality. Variables related to ownership of limbs in virtual reality e.g. “I sometimes felt as if my hand was located where my virtual hand was to be” the illusion of movement which looked at how much your virtual arm impacted on the movement of your real arm, validity which looked at how your movements impacted on your virtual arm and control regarding how much control you had of your virtual arm. The Embodiment Questionnaire uses a 7-point Likert scale in which you rate how much you agree with the statement (Appendix 1). The other questionnaire required for this study was “The Virtual Presence Questionnaire” which was an adapted version from Usoh’s paper looking at presence questionnaires (Usho, Catena, Arman, & Slater, 2000).
