Age differences in cognitive performance: A study of cultural differences in Historical Context

Ethnicity and cultural experience can affect neuropsychological performance, but they are rarely assessed in historical context. Attention measures are considered strongly biologically determined and therefore potentially culture‐fair. In this study, we assessed the cross‐cultural equivalence of Spanish and English versions of the Trail Making Test (TMT; Reitan, 1958, Perceptual and Motor Skills, 8, 271–276) and the Brief Test of Attention (BTA; Schretlen et al., 1996, The Clinical Neuropsychologist, 10, 80–89) in two large samples of Americans (N = 203) and Spaniards (N = 213), divided into younger and older subgroups. The older Spaniards lived under Franco's political regime (1936–1975), whereas the Americans never experienced such repression. Overall, TMT performance was culture‐sensitive, whereas BTA performance was not. However, when both groups were stratified by age, cultural differences in TMT performance were restricted to older participants, suggesting that historical experience across generations might have contributed to the observed differences in cognitive performance. Even such basic cognitive processes as attention, working memory, and resource sharing might be shaped to some degree by historical experiences that contribute to cultural differences.

Effect of Romantic Relationship on Implicit Regional Prejudice

The study measures both the implicit regional prejudice and the explicit simple attitude of 93 students of five universities in China, either involved or not in different stages of a romantic relationship and at varying distances from their partners, by using the Brief Implicit Association Test and Explicit Reports. Results indicate that close relationships can contribute significantly to decreasing implicit regional prejudice. Further studies are needed to provide support for the causal mechanism between interpersonal relationships and changes in social attitudes. Copyright © 2014 John Wiley & Sons, Ltd.     

The Hopkins Verbal Learning Test: an in-depth analysis of recall patterns

One of the earliest signs of dementia is memory issues and verbal word lists, such as the Hopkins Verbal Learning Test (HVLT), are successfully used for screening. To gain insight in how memory is affected in dementia, and to further improve the efficacy of the HVLT, in-depth analysis of the recall patterns of dementia cases and controls was conducted. Dementia cases and controls were matched for factors that can affect performance, such as age, gender and education level. Word frequency, syllable length, and orthographic neighbourhood size did not differ in the Indonesian version of the HVLT, nor did these characteristics affect recall. However dementia cases showed consistent and poor recall across the three trials; with the worst recall for the “human shelter” category and best recall for the “animals” category. Dementia cases also showed impaired accessibility of all categories with reduced subsequent recall from accessed categories and reduced primacy and recency levels. Finally, dementia cases exhibited lower levels of re-remembering and recalling new words, and higher levels of immediate forgetting and never recalling words. It was concluded that utilising the extra information provided by the in-depth analyses of the recall patterns could be beneficial to improve dementia screening.     

Behavioral adaptations of human drivers interacting with automated vehicles

Advancements in technology are bringing automated vehicles (AVs) closer to wider deployment. However, in the early phases of their deployment, AVs will coexist and frequently interact with human-driven vehicles (HDVs). These interactions might lead to changes in the driving behavior of HDVs. A field test was conducted in the Netherlands with 18 participants focusing on gap acceptance, car-following, and overtaking behaviors to understand such behavioral adaptations. The participants were asked to drive their vehicles in a controlled environment, interacting with an HDV and a Wizard of Oz AV. The effects of positive and negative information regarding AV behavior on the participants’ driving behavior and their trust in AVs were also studied. The results show that human drivers adopted significantly smaller critical gaps when interacting with the approaching AV as compared to when interacting with the approaching HDV. Drivers also maintained a significantly shorter headway after overtaking the AV in comparison to overtaking the HDV. Positive information about the behavior of the AV led to closer interactions in comparison to HDVs. Additionally, drivers showed higher trust in the interacting AV when they were provided with positive information regarding the AV in comparison to scenarios where no information was provided. These findings suggest the potential exploitation of AV technology by HDV drivers.     

Psychological ownership: The implicit association between self and already-owned versus newly-owned objects

Evidence from explicit measures (e.g. favourability ratings, valuations) has led to the prevalent hypothesis that owned objects become cognitively associated with self-concept. Using a novel version of the Implicit Association Test (self-object IAT), wherein participants categorized objects by colour, we evaluated implicit cognitive associations involving self with already-owned and newly-owned objects. We observed faster responses when self-related words required the same response key as the colour that incidentally corresponded to self-owned objects, irrespective of length of ownership. These findings suggest that participants efficiently form cognitive associations between self and self-owned objects within mere minutes of ownership induction and inspire questions about the extent to which length of ownership drives the strength of this association.

Brain activation patterns in response to complex triggers in the Word Association Test: results from a new study in the United States

C.G. Jung's theory of psychological complexes lies at the root of analytical psychology theory and practice. Functional magnetic resonance imaging (fMRI) provides a powerful tool to validate the theory of complexes and eludicate the neuropsychologic mechanisms underlying the unconscious activation of significant memories. In this study, using fMRI, we identify two brain circuits which are activated in response to complex triggering words. Circuit one involves brain regions involved in episodic memory and somatic (body) responses and the experience of uncertainty. A second circuit involves episodic memory, emotion, visual and language association, and semiotic meaning. Specific brain regions include the right prefrontal cortex, SMA cortex, left temporal cortex, and the caudate and cingulate. These brain circuits may be thought of as the biological form in which complexes are experienced. Implications for analytic psychology practice and theory are discussed.     

L’examen psychologique dans le handicap visuel : intérêts et limites méthodologiques

The psychological assessment of visually impaired people (blind or partially sighted) confronts the psychologist with methodological constraints regarding the choice of assessment tools. Both critical judgement and an extensive psychometric knowledge are necessary. The objective of this article is to present the results of a study in which the existing tools in this field are identified. The results of this study bring to light the shortage of tools and methods of investigation specifically designed to assess the different psychological facets (affective, cognitive or conative) of visual impairment. We will then examine the methodological and psychometric issues specifically related to assessment in the field of visual impairment. Although some tools have psychometric qualities for the assessment of blind and visually impaired people (Miller & Skillman, 2003; Reid, 1997), we note that the limits of some tests are often overlooked or ignored (Reid, 1997; Tobin, 1994; Tobin & Hill, 2011). Questions relating to the use, adaptation and translation of foreign language tools are examined. In order to illustrate these points, we present some practices used by psychologists which highlight the limits of currently existing tools for the assessment of the psychological, in particular, the cognitive facet, and in addition provide some recommendations for assessment.     

The association of sleep disturbances with endocrine and perceived stress reactivity measures in male employees

Evidence on the relationship between stress reactivity and sleep is conflicting. This study examined the association between disturbed sleep and perceived and endocrine stress reactivity independently of age, body mass index (BMI), and chronic stress. One hundred and twenty middle-aged men were exposed to the Trier Social Stress Test for Groups. The Pittsburgh Sleep Quality Index and the Perceived Stress Reactivity Scale were used to assess sleep and perceived stress reactivity, respectively. Endocrine stress reactivity was examined by assessing salivary cortisol levels. Regression analyses showed that men with disturbed sleep had blunted overall cortisol responses (b = −18.246, p = .044), but the association did not survive adjustment for age, BMI, and chronic stress. In contrast, poor sleep was associated with heightened perceived stress reactivity independently of age and BMI (b = 0.235, p = .005), but additional adjustment for chronic stress attenuated the relationship and only chronic stress remained a significant predictor of perceived stress reactivity (b = 0.470, p < .001). Cortisol and perceived stress reactivity were uncorrelated. In summary, our study indicates associations between sleep disturbances and stress reactivity were not independent of BMI and chronic stress levels, and endocrine and perceived stress reactivity were dissociated.
