Flexible target representations underlie repetition priming in visual search

Repeating target features across consecutive visual search trials can influence response time. Three experiments are reported that show that this repetition priming is dependent on the exact stimulus configuration and feature type. In Experiment 1 the target was defined relative to distractors by its orientation and target colour was task irrelevant. The roles played by these features were reversed in Experiment 2. Repeating target colour across trials speeded responses in both Experiments 1 and 2. Repeating orientation significantly slowed responses in Experiment 1 but had no significant effect in Experiment 2. Existing feature-based and episodic memory-based explanations of priming cannot account for these data, but instead more flexible explanations are required. Experiment 3 showed that significant positive priming results from repeating distractor-defining orientation, indicating that priming of pop-out effects previously reported in the literature may result from combined target and distractor effects.     

Prospective memory in young and older adults: The effects of ongoing-task load

ABSTRACT

Prospective memory involves remembering to perform intended actions in the future. Previous work with the multinomial model of event-based prospective memory indicated that adult age-related differences in prospective-memory performance were due to the prospective (not the retrospective) component of the task (Smith & Bayen, 2006 Smith, R. E. and Bayen, U. J. 2006. The source of age differences in event-based prospective memory: A multinomial modeling approach. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32: 623–635. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar], Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 623). However, ongoing-task performance was also lower in older adults in that study. In the current study with young and older adults, the difficulty of the ongoing task was manipulated by varying the number of colors per trial to create easier and harder versions of the ongoing task for each age group. The easier version included 2 colors per trial for older adults and 4 colors for young adults. The harder version included 4 colors for older adults and 6 colors for young adults. By adjusting the ongoing-task difficulty, older adults were able to perform the ongoing task as well or better than the young adults. Analyses with the multinomial model revealed that making the ongoing task easier for older adults (or more difficult for young adults) did not eliminate age-related differences in prospective-memory performance and the underlying prospective component.     

Age differences in three facets of empathy: performance-based evidence

This study investigated age differences in cognitive and affective facets of empathy: the ability to perceive another's emotions accurately, the capacity to share another's emotions, and the ability to behaviorally express sympathy in an empathic episode. Participants, 80 younger (M(age) = 32 years) and 73 older (M(age) = 59 years) adults, viewed eight film clips, each portraying a younger or an older adult thinking-aloud about an emotionally engaging topic that was relevant to either younger adults or older adults. In comparison to their younger counterparts, older adults generally reported and expressed greater sympathy while observing the target persons; and they were better able to share the emotions of the target persons who talked about a topic that was relevant to older adults. Age-related deficits in the cognitive ability to accurately perceive another's emotions were only evident when the target person talked about a topic of little relevance to older adults. In sum, the present performance-based evidence speaks for multidirectional age differences in empathy.     

Age differences in emotional reactions: arousal and age-relevance count

Recent findings suggest positivity effects in older adults' attention and memory, but few studies have examined such effects on the level of emotional reactivity. In this study, 52 young and 52 older adults rated 172 pictures of the International Affective Picture System, differing in arousal and age-relevance, in terms of valence and discrete emotions. Age differences in the ratio of pleasantness reactions to pleasant pictures vs. unpleasantness reactions to unpleasant pictures as well as age differences in absolute levels of unpleasantness and pleasantness reactions suggest that positivity effects in older adults' subjective emotional reactions are reduced under high arousal. There is also evidence that positivity effects may be restricted to stimuli with low relevance in old age.     

Effects of dysphoria and induced negative mood on the processes underlying hindsight bias

Hindsight bias is the tendency to overestimate one’s prior knowledge of facts or events once the actual facts or events are known. Several theoretical frameworks suggest that affective states might influence hindsight bias. Nondysphoric participants (n?=?123, BDI?≤?13) in negative or neutral mood, and dysphoric participants (n?=?19, BDI?>?13) generated and recalled answers to difficult knowledge questions. All groups showed hindsight bias, that is, their recalled estimates were closer to the correct answer when this answer was shown at recall. Multinomial modelling revealed, however, that under dysphoria and induced negative mood different processes contributed to hindsight bias. Dysphoria, but not induced negative mood, was associated with a stronger reconstruction bias, compared with neutral mood. A recollection bias appeared in neutral, but neither in induced negative nor dysphoric mood. These findings highlight differences between the cognitive consequences of dysphoria and induced negative mood.     

Staying on track: Planned goal striving is protected from disruptive internal states

Past implementation intention research focused on shielding goal striving from disruptive internal states (e.g., being anxious) by forming if-then plans that link these very states to instrumental coping responses. In the present line of research, we investigated whether planning out goal striving by means of if-then plans specifying opportunities to initiate goal-directed responses also protects goal striving from the negative impact of disruptive internal states. Indeed, in the face of disruptive internal states, participants who had been asked to form implementation intentions that targeted opportunities for initiating goal-directed responses outperformed participants with a mere goal intention to do well on a focal task goal. Actually, implementation intention participants performed as well as control participants who were not burdened by disruptive internal states such as being in a certain mood (Study 1), ego-depleted (Study 2), or self-definitionally incomplete (Study 3). Results are discussed by pointing to the importance of hypo-egoic self-regulation.     

Health of entrepreneurs versus employees in a national representative sample

Prior research has found entrepreneurs to experience significantly higher job control and job demands compared with employees. This suggests that entrepreneurs have so‐called active jobs and thus may benefit from positive health consequences. The present research compared entrepreneurs' health with employees' health in a national representative sample with regard to the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD‐10) diagnoses of somatic diseases, the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM‐IV) diagnoses of mental disorders, blood pressure, well‐being (life‐satisfaction) as well as behavioural health indicators (sick days, physician visits). Entrepreneurs showed significantly lower overall somatic and mental morbidity, lower blood pressure, lower prevalence rates of hypertension, and somatoform disorders, as well as higher well‐being and more favourable behavioural health indicators. The results are discussed with regard to the active job hypothesis and recommendations for future research are provided.     

Mindset effects on information search in self‐evaluation

Research on mindset theory (Gollwitzer & Bayer, 1999 ) observed that people in an implemental mindset show an orientation towards positive illusionary self‐evaluations, whereas people in a deliberative mindset opt for accurate self‐evaluations. In the present study, we tested whether these self‐evaluative orientations and the associated search for certain types of self‐relevant information (feedback) are moderated by low versus high self‐views. With high self‐view participants we observed the hypothesized mindset effects on information search, but we obtained the reverse pattern for low self‐view participants. The latter finding points to self‐defensiveness in low self‐view individuals. Implications are discussed in terms of the consequences of accurate versus positive illusionary self‐evaluations for the successful control of goal pursuits, and individual differences in mindset effects.

Helping Behavior as a Subtle Measure of Discrimination Against Lesbians and Gay Men: German Data and a Comparison Across Countries1

To unobtrusively assess attitudes toward lesbians and gay men, the wrong‐number technique was used in a field experiment in Germany. The results are compared to studies using the same paradigm in Switzerland, Great Britain, and the United States. This approach gives a realistic picture of intercultural differences in social behavior against lesbians and gay men. Across studies, the results indicated that homosexuals are less likely to receive help than are heterosexuals. The variation of this effect between countries closely corresponded to the ranking of attitudes toward homosexuality assessed in survey studies. Contrary to survey studies, however, women showed only marginally less negative attitudes toward gay persons than men, when actual helping behavior was used as an attitude index.
