Response Time Modeling Based on the Proportional Hazards Model

Tests of personality, interests, intelligence, and academic achievement were administered by 271 Ss. The data were processed by the principal component method of factor analysis. Twelve second-order factors were extracted and interpreted after oblique maxplane rotation.     

Effects of Changed Item Order: A cautionary note to practitioners on jumping to computerized adaptive testing for personality assessment

This study aims to investigate the effects of item order used with computerized adaptive testing (CAT) in the domain of personality assessment. Based on items from the German version of the Eysenck Personality Profiler, four test versions were designed from seven scales and presented to four experimental groups (n=362). One conventional and three adaptive versions were created, each beginning with items representing either medium or extreme trait levels. Results showed significant differences in average gained person parameters for three out of seven scales between the adaptive versions, as well as differences in average reaction times for answering the items. Results indicated context effects as a problem for using CAT to measure personality.     

A dichotic listening study of attention control in older adults

The influence of age on attentional control of bottom-up processing was investigated with a dichotic-listening paradigm. The typical right-ear-advantage (REA) without specific attentional instructions was used as a measure of bottom-up processing (non-forced condition). Top-down attentional control was evaluated by instructing subjects to report only the right or left ear stimulus of the dichotic pair (forced-right, forced-left conditions). Both young and old participants showed a REA in the non-forced condition and an increased REA in the forced-right condition. The old group failed, however, to use attention to modulate the REA to the same degree as the younger participants in the forced-left condition. Only the young group showed a significant left ear advantage (LEA). The results are discussed in relation to cognitive decline in normal aging and in early stages of dementia.     

Think ahead before you regulate: A focus on future consequences predicts choices of and beliefs about strategies for the down-regulation of negative emotions

Considering future consequences predicts many self-regulatory behaviors. Moreover, emotion regulation choices often involve trade-offs between immediate hedonic benefits and future well-being and mental health. We propose that focusing on future consequences may also predict emotion regulation choices. We examined whether people who consider future consequences of their actions are more likely to choose adaptive strategies and less likely to choose maladaptive strategies (Study 1) and whether people believe that adaptive and maladaptive strategies have differential short- and long-term consequences (Study 2). In Study 1, consideration of future consequences was related to choosing more adaptive and fewer maladaptive strategies for regulating negative emotions. In Study 2, participants believed that adaptive strategies are more effective in the short-term than in the long-term and that maladaptive strategies are more effective in the long-term than in the short-term. Moreover, commonalities in favored strategies were observed across the two studies. Taken together, the findings suggest that trait future time focus plays a significant role in emotion regulation preferences and that people have some knowledge about the varied temporal consequences of different strategies.     

In the eye of the examinee: likable examiners interfere with performance

We investigated effects of examiners’ ascribed likability and examiners’ gender on test performance during a standardized face-to-face testing situation assessing self-estimated and de facto verbal knowledge. One hundred fourteen nonpsychology students were individually tested by one of 22 examiners. A moderated regression analysis revealed a significant three-way interaction of test taker’s gender, examiner’s gender, and examiner’s likability on de facto knowledge: Men and women showed lower scores on de facto knowledge with a same-gender examiner rated as likable compared to their performance with a likable opposite-gender examiner or in interaction with a nonlikable examiner.     

Familiarity,Cued and Free Odor Identification and Their Association with Cognitive Functioning in Middle Aged and Older Adults

ABSTRACT

The aim of the present study was to examine the association between familiarity of odors, cued and free odor identification performance and cognitive function in elderly adults. It was further investigated how age affects performance on the various odor tasks. A third aim was to investigate the role of familiarity in explaining performance on the free identification task. One hundred and thirty-six participants (aged 45–79 years) with normal olfactory sensitivity were assessed with the Scandinavian Odor Identification Test (SOIT) and standardized tests of cognitive function. Familiarity did not correlate with any measure of cognitive function, while verbal identification performance was associated with several cognitive measures, although correlations were modest. In this sample, free odor identification was affected by increasing age to a marginally larger extent than cued identification performance and familiarity ratings. The results suggest that the different olfactory tasks involve different levels of cognitive processing.     

Development of flexible visual recognition memory in human infants

Research using the visual paired comparison task has shown that visual recognition memory across changing contexts is dependent on the integrity of the hippocampal formation in human adults and in monkeys. The acquisition of contextual flexibility may contribute to the change in memory performance that occurs late in the first year of life. To assess this skill, the images are presented on a background of one colour during familiarization and on a different coloured background during the recognition test. Our research showed that recognition memory is impaired by a change in context at 6 and 12 months of age but is unaffected at 18 and 24 months of age. The findings are discussed in relation to hippocampal development and the proposed developmental step in memory at 9-10 months of age.     

Mindfulness meditation and reduced emotional interference on a cognitive task

The effect of mindfulness meditation (MM) on attentional control in emotional contexts was examined. In Study 1, MM practitioners (N = 28) categorized tones presented 1 or 4 s following the onset of affective pictures. Reaction times (RTs) to tones for affective minus neutral pictures provided an index of emotional interference. Participants with more MM experience showed less interference from affective pictures and reported higher mindfulness and psychological well-being. Study 2 was a controlled, randomized experimental study in which participants (N = 82) received MM training, relaxation meditation (RM) training, or no intervention (waiting-list control; WLC). Behavioral, self-report, and psychophysiological measures were administered before and after a 7-week intervention period. Although both MM and RM resulted in smaller skin conductance responses to unpleasant pictures and increased well-being, reductions in emotional interference from unpleasant pictures were specific to MM. These findings indicate that MM attenuates prolonged reactivity to emotional stimuli.

Where are the Gender Differences? Male Priming Boosts Spatial Skills in Women

The effects of gender stereotype activation by priming on performance in a spatial task were investigated among a mixed adult sample (including students) of 161 men and women (mean age?=?31.90) from Austria (Europe). They were assigned to one of four experimental groups according to gender and stereotype activation condition. After a male or female gender stereotype activating task, participants worked on a test assessing mental rotation (three-dimensional cube test, Gittler 1990). A significant main effect of priming on the performance in the mental rotation task emerged. Cohen’s d showed a pronounced gender difference emerging only in the female priming condition (d?=?.59), whereas it disappeared in the male priming condition (d?=?.01).
