The Effects of Different Sleep Stages on Language Learning Tasks in Young Adults
subject: Language learning, novel generalisation, REM, sleep, sleep spindle density, sleep stages, speech segmentation, SWS
description: In order to learn a language, one must practice multiple tasks, including speech segmentation and generalisation. Segmenting speech allows for the identification of words and learning the meaning as well as syntactic role of those words within phrases and sentences. Novel generalisation requires generalising over the structure of a new language not yet experienced. Frost and Monaghan (2016) showed that participants were able to use the same statistical information at the same time to complete both language tasks. They suggest that segmentation and grammatical generalisation are dependent on similar statistical processing mechanisms. The role of sleep for learning to segment and generalise language is still unclear. Sleep affects memory consolidation, which is necessary for learning a novel language. This refers to the amount of sleep individuals get within their sleep cycle, yet it is unknown whether the duration of separate sleep stages has an effect. The declarative/procedural (DP) model by Ullman (2004) on learning provides distinctions in DP memory that associate with slow-wave sleep (SWS) and rapid-eye movement (REM) sleep respectively. SWS has a role in declarative memory processes, including memory for words and grammar. Rapid-eye movement (REM) sleep has a role in procedural memory processes, involving motor skills and coordination. Sleep spindle density should also be considered, as spindles are involved in offline information processing and information transfer. It was found that increased SWS and stage 2 spindle density have a positive effect on speech segmentation compared to generalisation.

source: Participants The original experiment was completed by 54 participants, 8 males and 46 females, with an age range of 18-24-years-old (mean age = 18.52). All participants reported being native-English speakers, with no history of auditory, speech or language disorders known. All participants either received university course credit or £20 for completing the experiment. Observations may be excluded for the first linear mixed-effects model. Exclusions may come from participants in the sleep group who did not sleep during the permitted time. This is because the first analysis aims to compare sleep vs. wake. The same participants’ data will be kept for the other linear mixed-effects models which aims to compare duration of sleep stages. This research received ethical approval by Dr Padraic Monaghan and Lancaster University’s Psychology Department on 22/04/2021. Design This study had a between-participants design with two conditions: sleep vs. wake between training and testing, and test type. There were two test types of speech segmentation and novel generalisation. Participants were randomly allocated to the sleep or wake conditions, and split evenly, meaning 27 participants slept and 27 remained awake. This study had access to PSG data for 18 of the participants in the sleep group. All participants received both test types. All participants were provided with an information sheet and gave written consent before the study commenced. Materials Stimuli Using the Festival speech synthesiser (Taylor et al., 1998), speech stimuli were created that were based on similar stimuli used by Peña et al. (2002). This artificial training language contained monosyllabic items, of which there were nine (pu, ki, be, du, ta, ga, li, ra, fo), used to form three different non-adjacent pairings with three possible X items in-between (A1X1–3C1, A2X1–3C2, and A3X1–3C3) (Frost & Monaghan, 2016). Using Peña et al.’s (2002) study, A and C items contained plosive phonemes (pu, ki, be, du, ta, go) a…

The Effects of Posture on Body Part Width Representations
subject: Body perception, affordances, somatosensation, visual perception
description: Despite the ubiquity of our bodily experiences, our representations of our body’s size are not geometrically accurate. For example, when estimating the length of body parts using the hand as a metric, consistent patterns of distortions across body parts are observed. Given the presence of these distortions, some have proposed that representations of length and width emerge directly, or indirectly, from the organisation of somatotopic maps in somatosensory cortex, rather than from their actual relative dimensions. However, whilst length representations are well researched with respect to this notion, less is known about representations of body part width across the body. Moreover, it is unclear from previous research whether body part width representations may be confounded by participants’ posture. Specifically, individuals have shown an enhanced tendency to overestimate body part width when seated upon a chair, suggesting that the chair may become incorporated into the body representation. Consequently, the aim of the current investigation was to further elucidate how width is represented across body parts and whether posture moderates these representations. Participants estimated how many hands widths made up the width of the back, shoulders, hips, torso, thigh, and head in one of three conditions: standing (n = 37), seated upon a chair (n = 33), or seated upon a backless stool (n = 39). Whilst estimates did differ across body parts, no effect of posture was observed. Moreover, the patterns of distortions observed differed from those seen in previous investigations. Results therefore indicate that body part width representations are neither accurate nor fixed, rather, they show distortions which vary across individuals and contexts. It is proposed that inter-individual heterogeneity in width representations may result from humans possessing alternative perceptual mechanisms for judging aperture passability. Therefore, maintaining fixed width representations is unn…

source: Method Participants Ethical approval for this study was obtained from Lancaster University Psychology Department on 31st May 2023. As this study aimed to investigate body part width representations in healthy populations, only participants aged 18-55 years without any physical, or mental impairment were included in the study. However, as previous research (Readman et al., 2021) using the same paradigm for length estimates has shown no influence of anxiety or depression on body part estimates, participants with diagnoses of these conditions were not excluded. Participants were excluded if they had any current or historic diagnosis of cognitive impairment, as this can affect instruction comprehension (Han et al., 2011), or visual impairment, to ensure difficulties in seeing the body parts did not confound findings. Furthermore, given the associations between other psychiatric impairments (e.g., Priebe & Röhricht, 2001), neurological impairments (e.g., Blanke et al., 2004), or eating disorders (Mölbert et al., 2017) with distorted body perceptions, individuals with a current or historic diagnosis of a condition falling within any of these categories were excluded. A total of 123 (61 females) participants ranging from 18 to 68 years (M = 28.80 years, SD = 10.79) were recruited via opportunity sampling for this study. Participant recruitment was ended before the required N = 150 due to time constraints. All participants were entered into a draw to win one of two £25 vouchers as an expression of goodwill. A total of 15 participants were excluded for failing to meet the inclusion criteria, leaving a final sample of N = 108 (50 females). Participants were aged 18 to 55 years (M = 27.98 years, SD = 9.56); the majority of participants were right-handed (n = 99) and over half the participants had normal vision (52.78%), with the remaining participants having corrected-to-normal vision. Reasons for exclusion included a current or historic psychiatric impairment (n = 2) or eatin…

The Effects of Schema-typical and Atypical Contexts on Memory for Brand Names of Products
subject: Distinctiveness effects Schema Memory Product recall Product recognition Brand recall Brand recognition Product-brand binding
description: The memory for an advertisement can be affected by the way it is constructed. In general, the more distinctiveness, the better memory performance. Traditionally, it has been assumed that the whole memory episode will be better remembered if it is featured by any odd element(s) because it is more attention-demanding and creates stronger memory traces. However, recent evidence suggests that the distinctiveness effect might not spread to everything; it might only affect those distinctive elements without necessarily affecting their linkages with other elements. Accordingly, regarding the advertisements, the memory for each element can be diverse. We manipulated the distinctiveness effect by composing products with schema-typical contexts (undistinctive condition) and schema-atypical contexts (distinctive condition). Participants observed 20 advertisements; 10 were schema-typical and another 10 were schema-atypical. They then completed recall and recognition tests which allowed us to explore how far the distinctiveness effect could extend. We found that only product recall and recognition in the schema-atypical condition were robustly enhanced, other variables were not significantly affected. These findings went against the traditional view and conform with the recent research. We discussed that, in the schema-atypical condition, the products and their contexts made each other distinctive, hence, they were better remembered. In contrast, the brand names and product-brand bindings were schema-neutral, thus, they did not receive more attention and not better remembered. The results were further interpreted to form some practical implications that improve advertising effectiveness.

source: The stimuli were 40 newly constructed print advertisements (in digital format). Print advertisements were employed because they allow the better experimental control (Keller, 1987). A half of these advertisements belonged to toiletries category (i.e. shampoo. sunscreen, and toothpaste), whereas another half belonged to foods category (i.e. pizza, sandwiches, and fried chicken). For each category, there were 10 types of products. For each product, there were two versions of its advertisement; schema-typical and schema-atypical (but only one of which was viewed by each participant). The schema-typical advertisements referred to the ones in which the product was bound with an expected context (i.e. a toothpaste appearing a bathroom scene), while the schema-atypical advertisements referred to the ones in which the product was bound with an unexpected context (i.e. a toothpaste appearing in a bedroom scene). In terms of the stimuli construction, there were three key elements for all advertisements, the first of which was the product, the second was the background or the scene illustration which was considered as the context of that advertisement, and the last element was the brand name. The first two elements were to form advertising pictures, and all together with the third one were to form complete advertisements. The researchers purchased stock images from Shutterstock website (https://www.shutterstock.com). The images purchased (product shots, backgrounds, and decorative elements) were then retouched and composted into the print advertising pictures using Adobe Photoshop (Adobe Photoshop CC 2015). All the advertising pictures were controlled not to include any text so that the only copy presented in each advertisement was its brand name. In respect of brand names, we invented new brand names for all 20 products. Each brand name was controlled to be easily pronounceable. They were names of between one to three syllables i.e. Hans, Raven, and Moana. The brand names, te…

The effects of screen exposure on developmental skills among children at two and three years of age.
subject: Developmental Psychology
description: Previous research into the topic of children’s development has tended to take place in Western nations (Kuta, 2017; Martinot, 2021). One aspect of development is language development, and one aspect of research on that matter is the use of electronic devices, with the potential for consequent effects on children’s language abilities. This paper reviews and builds upon the scope of the available research, with its disparate findings, by offering research from the context of Kuwait, a non-western nation where parents tend to be in favour of their children having access to new technologies regardless of their age (Dashti & Yateem, 2018). The increasing number of children being exposed to electronic devices of various descriptions raises concerns regarding the possible adverse effects of screen exposure on their development, particularly through displacement of educationally enriching activities, which provides the motivation here (Haughton, Aiken & Cheevers 2015). Based on a review of the existing literature, the present research starts from the hypothesis that language development will be negatively correlated with media exposure. Valid data relating to 96 children of 24 to 36 months of age were collected using two questionnaires, one relating to the child’s knowledge of Arabic words on various topics (voices of animals, names of animals, vehicles, toys, food and drink, etc.) and the other quantifying the child’s daily screen time. Ordinary least squares analysis was performed using SPSS, version 26. While a statistically significant positive moderate correlation between language expression score and age was found – an increase in age was associated with an increase in language expression or the number of words understood and expressed – no significant effect of screen time on language expression was found after adjusting for age. This indicates, therefore, the value of employing non-western populations in research into cognitive development, and suggests the need for…

source: The parents of a total of 100 participant children) took part in a questionnaire survey. The reports of 4 parents were excluded because their child’s age exceeded 36 months and the inclusion criteria for the study were set at 24 to 36 months. Participants were selected by means of opportunity sampling. An announcement was sent via WhatsApp to those of my contacts who had children of an age appropriate for inclusion in the study. Parents were recruited by sending a link to the survey through WhatsApp. Family and friends were then asked to deliver the WhatsApp number to those who they knew who had children within the set age range. Parents read information about the study and their informed consent to participate in the questionnaire survey was obtained via Qualtrics. The Lancaster University Psychology Department gave ethical approval for the present study. Procedure The data for the present work were gathered by means of an online questionnaire via Qualtrics between 7 June 2021 and 22 June 2021. During this time, participants submitted answers to two questionnaires: a) the Arabic CDI, which measures Arabic words arranged according to groups (for example voices of animals, names of animals, vehicles, toys, food and drink, etc.) to measure the child’s knowledge of the Arabic language (Abdel Wahab, 2020) and b) a questionnaire related to the number of hours the child spent in front of the screen , and their opinion of the appropriate amount of screen time which children can spend at their screens, as well as their control over their children’s viewing of the screens, and whether or not they are allowed to watch while sleeping and eating. The survey instruments were designed to measure the extent to which screen viewing is related to the language development of Kuwaiti children aged between two and three years.

The impact of retribution on perception of transgressor by others
subject: Retribution, Transgression, Guilt, Vignette
description: Emotions play a key role in within society, behaviour and human life with moral emotions such as guilt, regret and shame being able to influence individuals’ judgments and actions. For example, a person who experiences guilt will want to fix their wrongdoing that has caused this. There are times where these efforts to repair ones transgression, can lead an individual to self-punish in order to repair bonds with others and reduce negative consequences of the situation. The present study experimentally investigated the effect of self-punishment intensity on perceptions of a transgressor. Participants were randomly assigned to one of three conditions of self-punishment intensity (low, correct and high). Vignettes were manipulated for each condition and presented for participants to read for them to answer questions on their judgments of the transgressor (perceptions of guilt, shame, regret, moral character, and trustworthiness, their willingness to forgive the transgressor, how likely they thought they would reoffend in the future) and rated this on a Likert scale of 0-5. Participants allocated to low self-punishment had more negative perceptions towards the transgressor overall when compared to correct self-punishment. However, this was not found beyond this as no differences were seen for those within the high self-punishment condition

Qualtrics randomly allocated participants to one of the three conditions. Materials. A short hypothetical vignette was used to describe an event between two individuals; ‘Simon’ the transgressor and his friend, who he steals money from. With each of the punishment conditions, the vignette introduced the scenario with the same starting sentences to create the scene of someone performing a transgression against their friend with feelings of self-directed negative affect presented by the transgressor: Simon is out with his friends when he noticed that a member of his group has left their wallet unattended. Simon helps himself to the £40 that was in the wallet. His friend eventually realises that the money has been stolen and seems distressed. The next day, Simon feels bad for his actions and confesses to his friend that he took the money. The final sentence of the vignettes was manipulated for each of the three conditions. The sentence stated the amount of money returned to Simon’s friend, which was either less than originally taken (low punishment, £20), same amount (correct punishment, £40) or more than originally taken (high punishment, £60).

The Impact of Sleep Patterns on Emotion Regulation in Taiwanese Adolescents
subject: sleep patterns, circadian types, morningness-eveningness, on/off-peak time, emotion regulation, cognitive control, adolescents
description: Emotion regulation has been shown in a number of studies to be related to sleep, which often suggested that good sleep quality leads to better emotion regulation. However, research which has empirically documented the link between individuals’ specific sleep patterns/circadian types and emotion regulation among adolescents is scant. Therefore, the aim of this study attempts to explore whether there is an interaction between circadian types and the corresponding peak time on emotion regulation. Participants were 204 boys and 148 girls, who were from 13 to 16 years of age. The present study involved three questionnaires and two modified emotional Stroop tasks, including Facial-Emotional Stroop task and Lexical-Emotional Stroop task, as the assessment of emotion regulation. The analysis of the questionnaires and experiments was conducted through a series of multivariate ANOVA analyses in order to indicate whether there is a main effect of two independent variables or interactions on two emotion regulation. The results showed three main findings. Firstly, ‘morning people’ committed more error on facial tasks than ‘evening people’. Secondly, participants who attended the tasks in the afternoon had faster reaction times on Lexical task than who were tested in the morning. Thirdly, the interaction between circadian types and the corresponding peak time only showed in the evening group. To sum up, this study might be of importance in explaining the relationship between sleep patterns and emotion regulation in adolescents. Nevertheless, further studies for adolescents in investigating circadian types in relation to emotion regulation are needed.
creator: Jhih-Ying, Chen
source: Materials Each participant was asked to complete three online questionnaires about sleep and mood as well as two experimental tasks about emotion regulation. Three questionnaires had been translated into a Chinese version and inspected by a native Chinese-speaking professor in the Department of Psychology at Lancaster University. Sleep Measures. Circadian Types Questionnaire. Participants were given a Morningness-Eveningness Questionnaire (MEQ) (Horne & Östberg, 1976) to assess when their biological clock can achieve peak alertness, which indicates the better timing for people to behave more efficiently in their work and cognitive, behavioural and emotional functioning (see Appendix A). Three groups were be categorized based on the MEQ score: score > 58 for the morning type, 42 < score < 58 for the Intermediate type and score < 42 for the evening type. Sleep Quality Questionnaire. To assess whether participants have sleep dysfunction, participants were also asked to fill out the Pittsburgh Sleep Quality Index (PSQI) (Buysse, Reynolds, Monk, Berman & Kupfer, 1989), which elicited information concerning their sleep quality (see Appendix B). The higher score the participants gain, the poorer sleep quality they have. This score can be used to examine whether people's sleep quality can influence their emotion regulation ability. Mood Measurements. Emotional Problems Questionnaire. Participants needed to fill out the Depression Anxiety Stress Scale-21 (DASS-21) (Antony, Bieling, Cox, Enns & Swinson, 1998), which is a self-reported measure to record their mood during over one recent week (see Appendix C). There were three dimensions of negative mood in this questionnaire, including depression, anxiety and stress. Each dimension had an independent score, with a higher score indicating more emotional problems. In this study, three sub-scores were added together to produce a composite measure of emotional difficulties. Emotion Regulation. In addition to the questionnaires, pa…

The Impact of Spatial Locations Involving Schema Representations on False Memories
subject: Schema, false memory, source monitoring, distinctiveness heuristic, object-location binding.
description: While numerous studies have investigated the effects of schema on false memories, few have looked at how schematic framework involving spatial locations have influenced levels of true and false memories in different age groups. For this study, two separate analyses were conducted; both analyses required participants to study four environment scenes, which contained schema- consistent objects that were placed in either schema-expected or schema-unexpected locations and schema- irrelevant objects. After each scene, a distractor task was presented, followed by the test scene. In the first analysis, false memory rates were examined by adding objects, which were not present during study, into test scenes; in the second analysis, false memory rates were assessed by shifting schema-consistent objects from a schema-expected to a schema-unexpected location or vice versa between study and test scene. In both analyses, target objects that remained in the same location for both study and test scenes assessed for true memories. Three different age groups were studied; younger children aged seven and eight, older children aged nine and ten, and adults who were university students. Results revealed that overall, adults were more schema-bound, and had significantly higher levels of true memories as well as significantly lower levels of false memories compared to younger and older children. Furthermore, schema-inconsistent objects attracted lower levels of false memories across all age groups. However, objects that shifted from a schema-unexpected to a schema-expected location yielded high false memories for object-location pairing. This study is of particular significance to the field of forensic psychology.

source: The experiment was programmed using a computer software called Psyscript and was run on a Mac laptop. Four different environments were used during the experiment, which were a kitchen, a living room, an office and a bathroom. For the practice run, a separate image, which was a seminar room, was used. All the photographs used were standardized across all four environments, with each photograph being 1300 x 864 pixels, to ensure that the quality and clarity of each photograph was the same. To every environment image, three different versions were prepared for the study scene, ensuring that all six of the schema-relevant target objects had the opportunity to appear in a schema-unexpected location, a schema-expected location, or not being present at all. Moreover, to every version, two test scenes were prepared, to create a variation between which of the target objects that were initially placed in schema-relevant or schema-irrelevant locations during study phase would be shifted during the test scene. Figure 1a is an example of a bathroom scene during study phase and Figure 1b is an example of the test scene for that version. The program had been set to ensure that the sequence of the four different environment images would be pseudo-randomized for counterbalancing purposes, in which all the scenes were presented once, whereas the versions and test scenes selected were randomized. Moreover, the target objects that were circled during the test scenes were also pseudo-randomized, in which each object would only be circled once. For the practice run, both the study scene and the test scene were presented in a hardcopy form, which was laminated. Two separate slips of paper were prepared, one being “Was this object anywhere in this picture before?” for the participants allocated to the Presence condition, and “Was this object in this place before?” for the participants allocated to the Location condition.

The Paradox of Choice in fictitious COVID-19 vaccination scenario: the role of the number of options and the amount of information in decision-making.
description: Previous research evidence showed that when people face abundance of choices or too much information, they tend to experience the paradox of choice. This study investigates the role of the number of options and amount of information in decision-making, respectively, the paradox of choice in the fictitious COVID-19 vaccination scenario. Participants (N = 128) were randomly allocated to one of four experimental conditions. The conditions differed in the number of options (high – six options; low – two options) and the information (high – six pieces of information per option; low – two pieces of information per option). As a result, the four experimental conditions were: low options, low information; low options, high information; high options, low information; high options, high information. Participants were asked to choose one of the vaccines from a list presented separately from the experimental stimuli. The reaction time of choosing a vaccine was measured. Participants were asked to evaluate how satisfied they were with their choice, how confident they were about their choice and their anticipated regret. Participants were also asked to write the reason why they chose a particular option. The study did not find a significant effect of the number of options and the amount of information on the decision-making. Participants identified five main themes why they chose a particular option: features of the vaccine, scientific evidence, information, lawfulness, and personal preference. The study revealed positive relationships between choice satisfaction, confidence, and anticipated regret.

source: Participants The participants’ pool was collected from the general public. In total, 191 participants took part in the study. However, 62 participants were excluded due to missing values. Another participant was further excluded because of stating being 0 years of age. Thus, the data of 128 participants (36 males, 90 females, 1 non-binary/third gender, and 1 prefer not to say) were used for the analysis. The participants were in the age group between 18 and 51 years of age (M = 23.1, SD = 6.02). Based on power analysis when effect size f = .25 (medium effect), p = .05, power (1 – β error probability) = .80, and the number of groups = 4, it was indicated that the sample size of 128 participants is necessary to ensure the study results have high statistical power. In terms of age, one participant was stated to be 22,5 years old. For the analysis, this was taken as 22 years of age. The participants were invited to the research via Facebook post, Instagram story, and direct messaging friends and family circles. From the overall sample, 103 participants (29 males, 72 females, 1 non-binary/third gender, 1 prefer not to say) also filled an additional qualitative question investigating the reasoning behind the participants’ choice. As drawn from the overall sample, the age of participants responding to the qualitative question ranged from 18 to 47 years of age (M = 22, SD = 5.76).

The Relationship Between Perspective-taking, Lie Detection and Self-construal Among Taiwanese
subject: None
description: “Theory of Mind” (ToM) refers to an ability, which allows us to understand what other people may believe, think, know, feel. Also, ToM is considered to play an essential role in social interaction. Evidence suggests that improved ability to understand others’ mental states through training can also improve our ability to generate lies and understand what kind of situations people may lie. In addition, previous studies point that there are differences in lie-telling and perspective-taking between individualistic and collectivist cultures. Therefore, the current study aimed to investigate whether there is a relationship between the perspective-taking, lie detection and self-construal (individualism and collectivism). Data were collected from 40 typically developed adults in Taiwan (M = 23.98, SD = 2.99). Each participant was asked to complete three computer-based tasks, namely a perspective-taking task; a lie detection task, and a questionnaire of Auckland Individualism and Collectivism scale (AICS). The result showed that there is no relationship between the ability of perspective-taking and lie detection. Also, the people scored higher individualism will show better performance on pointing out truths, but worse on detecting lies. It might relate to the “truth bias”, which means that people will typically assume or believe others are telling truths rather than lies, especially distinguishing on individualists. However, because cultural effects such as language differences and self-construal might affect individuals’ performances on instances of ToM use, the current study suggests that people might need to use different cues to detect lies in a truth-versus-lie judgment between different cultures.

source: Participants Data were collected from 40 typically developing adults from an opportunity sample in Taiwan. The entire group was composed of 20 males and 20 females between the ages of 18 and 30 (M = 23.98, SD = 2.99). All participants stated that they were Taiwanese, speaking Chinese/Taiwanese Mandarin as their first language, with normal vision or vision which had been corrected to normal. All of the participants had not been diagnosed with any neurological or developmental disorders. The data of participant No.40 was excluded from analyses because the participant only responded with the same positive answer to each question in the lie detection task. The original minimum required sample size was 44, which was determined a priori by using G*Power software. This number was calculated based on assuming a medium effect size of 0.4 and a reasonable power of 0.8. However, 40 was considered as a more suitable sample size, as the experiment consisted of two orders for the perspective-taking task, four sub-sets of the lie detection task and a questionnaire. In order to counterbalance stimuli presentation, the target sample was set to 40, as it is a multiple of eight (two times four times one); it is also the closest number to 44. All participants had been given the consent form and the information sheet to understand the contents of the project before the tests began. Furthermore, this project was approved by the ethics process from the Department of Psychology at Lancaster University. Design and Procedure Each participant was asked to complete three computer-based tasks, namely, the perspective taking task, the lie detection task, and a questionnaire of the Auckland Individualism and Collectivism Scale (AICS). All of the tasks were translated or designed in the participants’ first language, in this case, Chinese/Taiwanese Mandarin. All of the tasks were presented on a laptop and participants responded by using the computer mouse. The full session took around an hour in to…
