Aging and performance on an everyday-based visual search task

Research on aging and visual search often requires older people to search computer screens for target letters or numbers. The aim of this experiment was to investigate age-related differences using an everyday-based visual search task in a large participant sample (n=261) aged 20-88 years. Our results show that: (1) old-old adults have more difficulty with triple conjunction searches with one highly distinctive feature compared to young-old and younger adults; (2) age-related declines in conjunction searches emerge in middle age then progress throughout older age; (3) age-related declines are evident in feature searches on target absent trials, as older people seem to exhaustively and serially search the whole display to determine a target's absence. Together, these findings suggest that declines emerge in middle age then progress throughout older age in feature integration, guided search, perceptual grouping and/or spreading suppression processes. Discussed are implications for enhancing everyday functioning throughout adulthood.     

Audiovisual identity perception from naturally-varying stimuli is driven by visual information

Identity perception often takes place in multimodal settings, where perceivers have access to both visual (face) and auditory (voice) information. Despite this, identity perception is usually studied in unimodal contexts, where face and voice identity perception are modelled independently from one another. In this study, we asked whether and how much auditory and visual information contribute to audiovisual identity perception from naturally-varying stimuli. In a between-subjects design, participants completed an identity sorting task with either dynamic video-only, audio-only or dynamic audiovisual stimuli. In this task, participants were asked to sort multiple, naturally-varying stimuli from three different people by perceived identity. We found that identity perception was more accurate for video-only and audiovisual stimuli compared with audio-only stimuli. Interestingly, there was no difference in accuracy between video-only and audiovisual stimuli. Auditory information nonetheless played a role alongside visual information as audiovisual identity judgements per stimulus could be predicted from both auditory and visual identity judgements, respectively. While the relationship was stronger for visual information and audiovisual information, auditory information still uniquely explained a significant portion of the variance in audiovisual identity judgements. Our findings thus align with previous theoretical and empirical work that proposes that, compared with faces, voices are an important but relatively less salient and a weaker cue to identity perception. We expand on this work to show that, at least in the context of this study, having access to voices in addition to faces does not result in better identity perception accuracy.

The Inter-Life project: researching the potential of art,design and virtual worlds as a vehicle for assisting young people with key life changes and transitions

ABSTRACT

Careers work in the twenty-first century faces a key challenge in terms of digital technologies: to evaluate their potential for careers work in challenging settings. Given the rapidity of developments, technologies require evaluation in research innovations and naturalistic settings. Virtual worlds offer potential for careers and guidance work, and the therapeutic domain. To illustrate this, we present examples in which young people explore their feelings and ideas, plans and difficulties, while preparing for film-making. During this they develop important life transition skills. We argue that the power of virtual worlds – to support emotional and cognitive engagement – could be utilised in practice settings. We conclude that they are serious candidates as digital tools in the careers and guidance domain.     

Attitudes towards psychotherapy manuals among clinicians treating eating disorders

Clinicians have relatively low uptake and implementation of evidence-based psychotherapies for the eating disorders, and this problem appears to be associated with low use of manualized approaches. This study examines clinicians' positive and negative attitudes to manuals, and possible beliefs and emotional factors that might drive those attitudes. The participants were 125 psychological therapists working with eating-disordered patients. Each completed standardised measures of attitudes to manuals and emotional states. A number of beliefs about the content of manuals were associated with both positive attitudes to the outcome of treatment and negative attitudes to their impact on the treatment process. In addition, a more positive mood was associated with more positive attitudes. Suggestions are made regarding how attitudes might be made more positive, in order to facilitate the use of evidence-based therapies for eating disorders.     

Cross-National Replication of the Gender Identity Interview for Children

We administered the Gender Identity Interview for Children, a 12-item child-informant measure, to children referred clinically for gender identity problems in Toronto, Ontario, Canada (N = 329) and Amsterdam, The Netherlands (N = 228) and 173 control children. Confirmatory factor analysis identified a Cognitive Gender Confusion factor (4 items) and an Affective Gender Confusion factor (8 items). Patients from both clinics had a significantly higher deviant total score than the controls, and the Dutch patients had a significantly higher deviant score than the Toronto patients. In this cross-national study, we are the first to report on the validity of this measure to discriminate children with gender identity disorder from controls outside of North America.     

Sexual Attitudes and Double Standards: A Literature Review Focusing on Participant Gender and Ethnic Background

We conducted a review of literature regarding sexual attitudes and double standards, focusing on participant gender and ethnic background. We found that men had more permissive sexual attitudes than women, and that African Americans had the most permissive sexual attitudes, followed by White Americans, then by Hispanic Americans and Asian Americans. The literature regarding sexual double standards was mixed; some studies showed evidence of continued sexual double standards and some studies showed the absence of sexual double standards. In some studies, men were more likely to endorse the sexual double standard than women. We found only one article addressing sexual double standards using ethnic background as a quasi-independent variable; this research revealed that non-North American (Russian and Japanese) samples were more likely to endorse the traditional double standard, that sex is more acceptable for men than for women.

Aging and inhibition of a prepotent motor response during an ongoing action

Inhibitory functions are key mechanisms underlying age related decline (Park & Gutchess, 2000, in: Cognitive aging: A primer. Hove: Psychology Press), yet few studies have investigated their impact on everyday tasks involving action as well as cognition. Using an everyday-based go/no-go task we devised a motor analogy of traditional neuropsychological tests to investigate in 134 older (aged 60-88) and 133 younger adults (aged 20-59) the ability to inhibit a prepotent motor response during an ongoing action. Older adults produced more inhibition failures as expected, but more strikingly inhibitory errors were not all or none; even when the inappropriate response was successfully inhibited, difficulties controlling ongoing movements emerged from as young as people in their 40s. The ability to inhibit therefore does not ensure control of ongoing tasks, and traditional cognitive tests may be unable to detect such difficulties. Furthermore, performance did not covary with education or action speed. Implications for neuropsychological theory and assessing/enhancing functional ability are discussed.     

Different clues from different views: the role of image format in public perceptions of neuroimaging results

We examined whether different types of brain images affect readers' evaluations of scientific reports. Five different brain images were selected from the neuroscience literature: a whole brain, an inflated brain, a cross-sectional brain slice, a glass brain, and a topographic map. First, the images were subjectively rated by 31 nonexperts for qualities associated with realism and perceived complexity. Each of the five images was later presented alongside one of five fictitious neuroscience articles (image-text pairings counterbalanced), and a different group of 122 novices rated the accompanying articles for scientific reasoning. They also separately reported their familiarity with each image type. Brain images previously rated as more three-dimensional produced more positive evaluations of the articles with which they were presented. Perceived image complexity also showed a marginal nonlinear relationship with article credibility ratings. Our findings suggest that choice of image format matters when disseminating neuroscience research to the general public.
