Effect of Attention and Noise on Echoic Memory as Indexed by the N1-Adaptation.
subject: Attention, Noise, N1-adaptation, auditory sensory memory
description: There are numerous studies that support the notion that echoic memory is indexed by the adaptation of the N1 peak in auditory event related potentials (ERPs). Although the number research on the effects of parameters like noise and attention on the amplitude of the N1 is immense, to date there are no studies on the effect of these parameters on the adaptation of the N1. Here, I investigated the effect of noise and attention on the adaptation of N1, P2 and N1-P2. Secondary analysis was conducted on data collected from 33 participants in three conditions: passive recording condition (participant listen passively to stimulus while staring at a fixation cross); attention/oddball conditions (participant were task with counting the deviating tones); and noise condition where the tones are presented in white noise. Within each condition, two Stimulus onset intervals (SOI): 1.7 s and 3.5 were used in separate stimulus blocks and the ratio R = M1.7s / M3.5s was used as a dimensionless measure of adaptation. My results found no significant effect of noise an attention on the amplitudes and adaption of the N1, P2 and N1-P2. I propose that the lack of effect on the adaption of the ERPS might be due to noise and attention having a scaling effect on all of the amplitudes equally so that adaption lifetime is not affected. As this is the first study of its kind, further research will be needed to gain a better understanding of how adaptation is affected by these two factors.

source: Participants This project carries out secondary analysis on data from an EEG experiment with 33 human participants. The data was received from supervisor, Patrick May. The participants were all adult undergraduate and post graduate students at Lancaster University, with no self-reported hearing loss or neurological disorder. The experiment was approved by the research ethics procedures of the Department of Psychology, Lancaster University, and the participants provided written consent before the experiment began. Equipment and Procedure for EEG measurements Three dry electrodes were attached at locations: Fpz, Fz, Cz. Reference and ground electrodes were attached to the right ear lobe. For this report, only the data acquired from the Fz location was used as this is the channel that recorded the best ERPs for all the participants. The participants were directed to passively listen to stimuli while staring at a fixation cross and moving and blinking as little as possible. The stimuli comprised of 500-Hz pure tones with a duration of 100ms, including 10-ms linear onset and offset ramps. The stimuli were presented in blocks of 100 isochronous stimuli. The stimuli were presented binaurally via Sennheiser headphones using laboratory laptop and MATLAB interfaced with the Enobio EEG device in a soundproof chamber. Data was collected in three conditions: baseline passive recording condition (participant listen passively to stimulus while staring at a fixation cross); attention/oddball conditions (participant were task with counting the deviating tones); and noise condition where the tones are presented in white noise. Withing each condition, two Stimulus onset interval (SOI): 1.7 s and 3.5 were used in separate stimulus blocks. The order of experiments were randomised across the participants. Data Analysis The data was passband filtered at 1-30 Hz and sectioned into epochs of single trial data. To remove artefacts (e.g., due to blinking) 15% of epochs with the largest absolu…

Effects of service brands’ current marketing strategies on customer attitude and behaviour
description: This project investigated current marketing strategies used by service brands, including car insurance and household energy companies, on customer’s attitudes and behaviours. The investigation involved a nationally representative sample of 1,977 participants completing an online survey, along with 30 participants taking part in a supporting qualitative online community panel exploring customers’ attitudes in more depth. Descriptive analysis showed that although participants’ loyalty reasons and bad provider experiences were predominantly determined by price, service quality was also an important factor. When choosing service providers, participants showed no preference between price and service, however slightly preferred price over reputation. Furthermore, significant correlations were found for the majority of provider switching attitudes and switching behaviours. Segmentation analysis identified four types of customers based on awareness of offers and convenience to switch: ‘Passive Loyals’, ‘Sceptical Loyals’, ‘Loyal Opportunity Switchers’ and ‘Conditioned Switchers’. A pattern was found amongst age groups – the older the participant, the more likely they preferred new customer deals over loyalty offers, were more interested in price over service quality and brand reputation, and had more expertise in the service industry. Due to the importance of customer retention (Berry, 1983), results implied brands should focus on loyalty rewards, along with gaining customers’ trust in their service quality and reliability.

source: Materials and procedure The online survey included both closed and open questions, thus a mixture of quantitative and qualitative methods. Participants were asked a few demographic questions: their gender, age, employment status, type of residence, location, and how long they had been a UK resident. Those who had not been screened were quizzed on their switching and service provider behaviours and attitudes. The questions were repeated for each service type, depending on whether participants had confirmed to paying for, or making decisions on electricity, gas or car insurance, and whether they’re household energy was on a dual fuel package or organised separately. The questions that were repeated were a select few, which required separate data for each service type. These included inquiries into people’s prior switching behaviour, reasons for maintaining a relationship with their current provider, and any ‘bad’ experiences they had encountered with a service provider. This was then followed by general attitudinal scales concerned with loyalty and switching amongst service providers. The data was collected in Confirmit, a software used to create, monitor and analyse online surveys (http://www.confirmit.com/). The quantitative information was analysed in Reportal, Confirmit’s analysis feature. The qualitative answers were transferred into Microsoft Excel, and examined through the CIT (Flanagan, 1954). Stage 2: Method The second stage of the project involved segmenting participants into different groups, in order to identify different people’s needs and desires in regard to switching and loyalty, and how brands should consider different types of individuals in their marketing and advertising. First, segmentation dimensions were established, and every participants was assigned to a particular segmentation cluster. Secondly, the different segments were profiled to make each group as distinct as possible. Segmentation Identifying the segments was explorative, thus there w…

Examining the Effect of Anxiety on the Development of False Memory
subject: memory, generalized anxiety disorder, confidence-accuracy calibration
description: Up till the late 70s, people believed their memory worked in similar to a video-recorder, accurately collecting and storing every information seen and heard. This belief was brought to question after researchers started thorough investigation on memory, and found that in actuality memory is highly impressionable and prone to numerous errors such as the formation of false memories. There now appears to have been found many causes for the formation of false memories. However, limited to no research exists on the effect of generalized anxiety disorder (GAD) on formation of false memories. The present study aimed to investigate the effect of GAD on the development of false memories by using the misinformation effect paradigm. Confidence-accuracy calibration (CAC) was assessed as a secondary analysis. Participants (N = 100) were recruited through online means and took part in a 15-45-minute-long experiment involving neutral stimuli. The experiment consisted of a video of an event and were subsequently asked to read a text description with misinformation after partaking in filler tasks. Afterwards their memory of the original event was tested. Results demonstrate that GAD and false memory are not significantly associated. CAC analysis revealed that participants were relatively aware of when their memory had been distorted by providing low confidence ratings to more inaccurate items and higher confidence ratings to accurately recalled answers. Additionally, false memories created due to misinformation was significantly observed, though GAD did have any influence over this. To conclude, GAD does not contribute to the formation of false memories.

source: A total of 100 participants were recruited and provided with an online link through social media sites, ages ranging from 18-50. Out of the recruited participants, 66 identified as females, 31 as males, two as non-binary and, one preferred not to say. The link begins with the consent sheet, and once the participants click to agree, they were then redirected to the start of the experiment. Participant’s anxiety was tested by administering a standardized and validated tool, the Generalized Anxiety Disorder Questionnaire (GAD-7) (Spitzer et al., 2006), (see Appendix B). GAD7 has seven rating scale questions, and the participant’s anxiety was calculated by assigning scores of zero (not at all), one (several days), two (more than half the days), and three (nearly every day). Samples questions include “worrying too much about different things?” and “becoming easily annoyed or irritable?”. For scores ten and above, GAD-7 has a specificity of 82% and sensitivity of 89% (Kroenke et al., 2007). Cut-off points for the scores are a score of five for mild anxiety, ten for moderate anxiety, and 15 for severe anxiety. For the present study, participants who scored nine and below were grouped under “low” anxiety, and participants who scored ten and above were grouped under “high” anxiety. The stimulus set developed by Okado and Start (2005) were used for this study. Two neutral stimuli were obtained, and each stimulus consisted of 50 coloured digital images. These were compiled into a short video, with each image displayed for 300ms, and the whole video lasting 150s. Out of the 50 slides, 12 of them were critical, meaning these slides consisted of an item that would later be altered in the text description of the event, hence providing the misinformation. The two stimuli are summarized below. Stimulus One is about a female named Rachel who was doing her work at home, then feels hungry and checks her refrigerator for food, sees that there is not much at hand, and so goes grocery sho…

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…

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 …

Exploring the Effectiveness of Metaphors in Video Advertising - the Interaction Effect of Different Cultural Groups and Different Metaphors
subject: Marketing Psycholinguistics
description: Metaphors are often used in contemporary advertising, and previous research has confirmed that advertisements with metaphors are more effective than literal ones. At the same time, research into the role of metaphors has become more comprehensive, moving from traditional metaphor theories based solely on literal language to the study of the interactive effects of different modalities of metaphor (multimodal metaphor). The aim of this study was to understand the differences in the responses of different cultural groups when exposed to advertisements containing different types of metaphors (needs-highlighting metaphor vs. feature-highlighting metaphor). Based on this expectation, a 2 (cultures: British, Chinese) x 3 (advertisement types: feature-highlighting metaphors, needs-highlighting metaphors, and literal advertisements) designed experiment was conducted to test.
creator: Lesley Wu
source: Design To obtain statistics on the extent to which creative metaphor in video advertising contribute to the effectiveness of advertisement, a quantitative research method was used in this study. To test if there was an interaction effect between cultural group and metaphor types, this experiment had a 3×2 mixed design, with a within-subjects factor of advertisement type (feature-highlighting metaphors, needs-highlighting metaphors, and literal advertisements), and a between-subjects factor of participants’ culture (British and Chinese). The dependent variables were attitude toward the product/advert and purchase intentions. Participants Fifty-three participants were recruited through convenience sampling and participated in the study by completing an online survey. The responses obtained from participants who either did not complete the consent form or did not answer all the questions were excluded from the analyses. This led to a total of 40 responses retained: 20 from Westerners, 10 men and 10 women; 20 from Chinese participants, 9 men and 11 women. Table 1 provides an overview of the participants’ information in this experiment. Most of the participants are currently studying at Lancaster University, some of the Chinese participants are currently living in China. As the aim of the experiment was to look at cultural differences, therefore, no specific age restrictions were set. Materials In the current experiment, the selection of stimulus classification conditions was based on the setting of Pan's study in 2020. However, in order to investigate the pattern and consistency of people's responses under different conditions, the number of stimuli under each condition classification was larger in this experiment. The stimuli consist of 9 video ads in total: 3 ads each for the literal, feature-highlighting metaphor, and needs-highlighting metaphor conditions. All ads featured tangible products: perfume, body wash and deodorant, with 3 ads per product covering all 3 con…

Exploring the impact of rewards on contextual cueing effect
subject: contextual cueing effect, reward, selective attention
description: There is a huge amount of complex information about visual stimuli in the environment and the individual's visual processing system has a limited capacity to process this information, so selective attentional mechanisms prioritise the most valuable information. Fixed contextual cues in the environment help us to allocate attentional resources efficiently. In their study of context, Chun and Jiang proposed a contextual cueing effect (CC effect). This effect is likely to be an implicit learning resulting from selective attention. Specifically, subjects searched for the target faster in the repeated configuration than in the random configuration, as fixed contextual cues would help locate the target. It was found that this effect could be moderated by manipulating external motivation, i.e., reward. However, there is so far considerable debate as to whether high rewards can contribute to the cc effect, and whether rewards act on the cc effect or on the positional probability learning effect. The present experiment used a classical situational cueing task and a mixed between-*within group experimental design to explore the effect of reward on the contextual cueing effect. The experimental results show that high rewards did not contribute more significantly to the cc effect than low rewards, but high rewards did facilitate the target probability learning effect.

source: Participants Fifty-two Lancaster University students (20 identified as male and 32 as female; age M=23.9, SD=2.55 years, range: 19-33 years) participated in the experiment. Two participants were excluded from the final analysis (see below for details). All participants had normal or corrected normal vision. Participants were informed that the three participants with the highest scores in the experiment would receive a £20 Amazon voucher as a reward. At the end of the experiment, the three participants with the highest scores had received their £20 Amazon vouchers by e-mail. The experiment passed ethical review by the Department of Psychology at Lancaster University. All participants were shown a participant information sheet and signed a consent form to participate in this study prior to the start of the experiment. The Participant Debrief Sheet was presented to participants at the end of the experiment. Materials The materials were created and presented with the Psychophysics Toolbox Version 3 (Brainard, 1997) MATLAB (MathWorks, Sherborn, MA) toolbox. The stimuli were displayed on an MS-Windows machine on a screen with 1920 × 1080 pixels resolution and 60 Hz refreshing rate. Each display consists of 11 L-shaped and one T-shaped black 1.25° x 1.25° items, presented on a white background. The only T-shaped item in each display is the target, which has a 90° rotation clockwise (called left) or counterclockwise (called right). There were an equal number of times that the target was rotated to the left as it was rotated to the right across the experiment. The L-shaped distractors were randomly rotated by 0°, 90°, 180° or 270°. To increase the difficulty of the task (Jiang & Chun, 2001), the L-shaped items had a 4-pixel offset at the junction of the lines to make them similar to the T-shaped targets. In each display, all items were balanced within the quadrant of the display. This randomisation was carried out for each subject individually. Experiment design This experim…

Exporing the Effect of Visual Complexity on Recall
subject: #visualcomplexity #recall #free-recall #cued-recall #advertisements #simple #complex
description: This study was conducted to explore the effect of visual complexity on an individuals` recall of product brands and their attributes in either simple or complex adverts . Within the field of visual complexity, there has been contradiction as to whether complexity helps or hinders recall, this study aims to resolve this question. A survey was conducted to measure their free and cued recall for adverts that varied in their visual complexity. The complex advertisements were defined as having three objects included whilst the simple advertisements had only one object included. This was decided to align with the industry standard for defining visual complexity as set by Attneave (1954), Snodgrass & Vanderwart (1980) and Chikhman et al., (2012). A percentage scoring system was used to compare overall memory performance. The data showed that those in the simple condition performed better compared to those in the complex condition. However, this was not the case for every individual. The results found the effects of complexity to be marginally significant (p < 0.09); however, the study had limited power, and a replication with a larger population could provide a more complete picture of the influence of the independent variable. Whilst this study does not provide a definitive conclusion towards the effect of visual complexity, it does explore and provide an insight into the effects of complexity on recall of product attributes in advertisements.

source: PARTICIPANTS The larger the number of participants in a study, the better-protected results will be from extraneous variables. For this reason, the participants were collected through random snowball sampling (Emerson, 2015). Each condition had 22 participants, a minimum age of 16 being the only participation condition. The participants were randomly allocated to each one of the four experimental conditions, providing 88 total participants (N= 88). There were no gender requirements for participation (Females (N = 47), Males (N = 31), Other (N = 4)). The majority of participants were born in the U.K. (N = 46) or Poland (N = 35). The majority are currently residing in England (N = 57) or Poland (N = 21), but responses were still collected from further afield, such as France and the U.S.A. (N = 10). The majority of participants fell into the two youngest age categories, 16 to 18-year-olds (N = 22) and 22 to 27-year-olds (N = 37). General demographic information provided insight into the advertisement exposure in participants' generic routines. The majority of participants were native English speakers (N = 49). The majority of participants use streaming services (N = 76), of which just under half of the respondents said their service had adverts (N = 38). Participants also use ad blockers (N = 49). Just over a quarter of participants use cable T.V. (N = 27). When asked whether they pay for premium applications, the majority said ‘never’ (N = 60), occasionally (N = 16), sometimes (N = 9), usually (N = 2), whilst only one participant always pays for premium applications (N = 1). MATERIALS Firstly, two product categories were chosen, bottled water and soap bars, four brands were then selected per category (see table 1). There were 16 advertisements in total, eight for the simple and complex conditions, respectively.

Extending the Cortical Hyperexcitability Index
subject: Perceptual Aberrations, Cortical Hyperexcitability, Migraine, Aura, Tinnitus, Auditory Perception, Visual Perception, Hallucinations
description: Anomalous perceptual experiences are associated with underlying excitation of neural activity in the cerebral cortex, known as cortical hyperexcitability (Wilkins, 1995). This can be measured behaviourally by the pattern glare test, where migraineurs consistently show greater susceptibility to anomalous visual percepts in response to grating patterns than control participants (for review see Evans & Stevenson, 2008). Based on these findings, Fong, Takahashi and Braithwaite (2019) developed a screening measure of visual cortical hyperexcitability, the Cortical Hyperexcitability Index (CHi-II), through exploratory factor analysis. This project aims to create auditory-based items for the CHi-II. We know cortical hyperexcitability in the auditory cortex is also associated with a number of auditory symptoms in migraine such as heightened auditory sensitivity and a range of anomalous auditory percepts, ranging from tinnitus-like tones to multiple conversing voices (Vingen, Pareja & Støren et al., 1998; Miller, Grosberg, Crystal & Robbins, 2015). As such we created seven auditory items through adaptation of related questionnaire items and generating unique items based on phenomenology of patient descriptions; these refer to experiences of hearing voices or unexplained sounds under various circumstances, as well as sensitivity to noise. Exploratory Factor Analysis will be conducted on the CHi-II alongside auditory items to test which factor each item best loads onto, as well as using Cronbach's Alpha to assess internal validity. Results are discussed in terms of the debate on global versus localised effects of patterns of hyperexcitability, as well as implications for our understanding of multisensory anomalous perceptual experiences.

source: Method Participants Forty-five participants age 18-24 (M = 19.24) took part either for research credits or without incentive. Of these, thirty-seven (82%) were female and thirty-seven (82%) were right-handed. Prior to the main questionnaire, a pre-screening survey asked participants to declare any history of neurosurgeries (8.22%), neurological conditions (2.22%), psychological conditions (17.78%), ocular conditions (15.56%), epilepsy (0%), migraine (24.44%), or tinnitus (15.56%). Auditory Item Creation As with the original CHi-II, items were based on previous questionnaires measuring anomalous perceptual experiences (Sierra & Berrios, 2000; Bell, Halligan & Ellis, 2006) alongside patient reports of auditory experiences in migraine (Miller, Grosberg, Crystal & Robbins, 2015; Vreeburg, Leijten, Sommer & Sommer, 2016). These items were split into two categories: voice-hearing, and noise-hearing. We distinguished between hearing a single voice in item one ‘Do you ever hear a single voice talking aloud in your head without a clear source?’, or multiple voices in item two ‘Do you ever hear 2 or more unexplained voices talking with each other?’, as these are delineated in patient reports (Miller et al., 2015; Vreebrug et al., 2016). We also distinguish between hearing instructing voices in item three ‘Do you ever hear voices telling you what to do?’, and hearing voices which comment on thoughts and actions in item four ‘Do you ever hear voices telling you what to do, or commenting on what you are thinking or doing?’, as suggested by the CAPS and CDS (Sierra & Berrios, 2000; Bell et al., 2006). The first noise item asked participants about the occurrence of anomalous sounds in item five ‘Do you ever notice sounds, such as ringing / buzzing , which other people around you cannot hear?’ as recommended by CAPS and CDS (Sierra & Berrios, 2000; Bell et al., 2006). The final noise items referred to volume of sounds in item six ‘Do you ever become annoyed or agitated by sounds th…

Eye tracking and Attention Deficit Hyperactivity Disorder (ADHD): Can eye tracking identify the feigning of ADHD?
subject: Eye-tracking, ADHD, Feigning, Prosaccade task, Anti-saccade task, latency, error rate, eye movements
description: When diagnosing adult ADHD, it has proven difficult for clinicians to detect deceptive behaviour. Diagnosis of ADHD comes with economic, academic, and recreational benefits, which may account for the increasing feigning of the disorder. Current diagnostic methods: clinical interviews and self-report scales can be easily manipulated for a positive diagnosis. Hence the present study evaluated the utility of eye tracking devices to detect the feigning of ADHD. Eye movements of 38 participants (7 ADHD, 15 healthy controls, and 16 healthy feigners) were captured throughout the prosaccade and anti-saccade task. The performance of the participants on the task was evaluated in terms of latency and the percentage of error rate. The findings of the study reveal a significant difference in the latency of anti-saccade tasks i.e., feigners have an increased latency compared to healthy controls and ADHD participants. Because of the limited sample size, study findings cannot be generalized. Further investigations are needed with a much larger sample.
creator: Reva Maria George
source: Method Participants Previous studies explaining feigning in ADHD acquired data from around 90-100 samples (Booksh et.al., 2010; Frazier et.al., 2008; Harrison et.al., 2007). The study therefore aimed to recruit 90 participants, 30 each in ADHD, healthy controls, and healthy feigners faking the disorder. Participants with and without a clinical diagnosis of ADHD were selected using the opportunity sampling method. A total of 42 participants between the age of 18-35 volunteered and were recruited for the study through the university disability service (11%), posters (16%) and through word of mouth (73%). Data of two participants were removed as the eye tracker repeatedly lost the pupil during recording. All participants were rewarded with an equal chance to win one of 6 £25 vouchers. Thirty-one of the 42 participants were healthy younger adult controls. Of the healthy control participants 15 (7 females; Mage = 24.33; SDage=4.32) participated as healthy controls, and the remaining 16 (9 females; Mage = 24.25; SDage=1.88) as healthy feigners. Seven ADHD participants (6 females) with a mean age 22.71 (SD=2.22) completed the study. The severity of the ADHD symptoms was analysed using the Adult ADHD self-report scale (for more demographic details see Table 1).
