作业时间和指导语导向对10-12岁儿童发散性思维的影响

研究者以239名10岁、11岁和12岁的儿童为实验对象,采用四种作业时间(2分钟、4分钟、6分钟和8分钟)和两种指导语导向(无导向、导向独特性)为实验条件,考察了这些条件对儿童发散性思维的影响.结果发现,作业时间和指导语导向对儿童发散性思维的流畅性,变通性和独特性均有明显的影响.在该实验条件下,发散性思维的三个指标随作业时间的增加而增加.有导向组儿童的发散性思维作业成绩显著高于无导向组.另外,在各实验条件下,儿童的作业成绩都有随着年龄的增长而上升的趋势.

The motion aftereffect reloaded

The motion aftereffect is a robust illusion of visual motion resulting from exposure to a moving pattern. There is a widely accepted explanation of it in terms of changes in the response of cortical direction-selective neurons. Research has distinguished several variants of the effect. Converging recent evidence from different experimental techniques (psychophysics, single-unit recording, brain imaging, transcranial magnetic stimulation, visual evoked potentials and magnetoencephalography) reveals that adaptation is not confined to one or even two cortical areas, but occurs at multiple levels of processing involved in visual motion analysis. A tentative motion-processing framework is described, based on motion aftereffect research. Recent ideas on the function of adaptation see it as a form of gain control that maximises the efficiency of information transmission at multiple levels of the visual pathway.     

Effects of cognitive load presence and duration on driver eye movements and event detection performance

This study examined the effects of cognitive load on driving performance for interactions with an in-vehicle information system (IVIS) that varied in duration from 1 to 4 min. Twelve participants drove in a simulator while intermittently performing the IVIS task. There were three IVIS conditions: interacting with the IVIS, non-IVIS periods between IVIS interactions, and baseline driving without the IVIS task. Contrary to our hypothesis, driver response to lead vehicle braking was surprisingly uniform across IVIS conditions. IVIS interaction did undermine driver ability to detect the bicyclist along the side of the road, and some of these performance decrements persisted after the IVIS interaction had ended. Reaction time for bicyclist detection increased from the first to the subsequent minutes of the interaction. Eye movements were influenced by the IVIS conditions but not by task duration. Both ANOVA and factor analyses revealed that some of the changes in eye movements were concurrent with IVIS interaction while others persisted after the driver completed the IVIS interaction. Overall, the findings suggest that two mechanisms might account for the distraction-related performance decrements in this study: competition for processing resources and interference due to activation of competing goals.     

Social mobbing calls in common marmosets (Callithrix jacchus): effects of experience and associated cortisol levels

We compared the mobbing response to model snakes of two groups of captive-born common marmosets (Callithrix jacchus) differing in genetic relatedness, age and past experience. Mobbing vocalisations (tsik calls), other mobbing behaviour and attention to the stimulus were recorded for 2 min. intervals pre-exposure, during exposure to various stimuli and post-exposure. Marmosets in one group were vocally reactive to all stimuli, although more so to one particular stimulus resembling rearing snakes and modified images of it, whereas the marmosets in a younger and genetically unrelated group attended to the stimuli but made very few mobbing calls. The parent stock of the first group had suffered stress in early life and had developed a phobic response to a specific stimulus, which they had transmitted to their offspring. A third group, matching the older group in age range but genetically unrelated, was also found to be unresponsive to the stimulus that elicited the strongest response in the first group. Cortisol levels in samples of hair were assayed and a significant negative correlation was found between the number of tsik calls made during presentation of the stimuli and the cortisol level, showing that mobbing behaviour/behavioural reactivity is associated with low levels of physiological stress.

Evaluating the invariance of the factor structure of the EPQ-R-N among adolescents

We examined the factor structure of the Neuroticism scale of the Eysenck Personality Questionnaire (EPQ-R-N; S. B. G. Eysenck, Eysenck & Barrett, 1985) and its factor invariance across sex and racial/ethnic groups in a sample of 1,979 adolescents. Using confirmatory factor analyses, we compared a hierarchical model to previous models of the EPQ-R-N and to single-factor and 3-factor structures. The hierarchical factor structure in which a general factor coexists with 3 group factors (depression, social concerns, and worry) was superior to alternative models. The general factor accounted for more than 60% of the variance in EPQ-R-N total scores and was invariant across sex and ethnicity. The 3 group factors varied across ethnicity and sex. We discuss the implications of these findings for conceptualization and assessment of neuroticism using the EPQ-R-N.     

Family metaphors and moral intuitions: how conservatives and liberals narrate their lives

This research examines life-narrative interviews obtained from 128 highly religious and politically active adults to test differences between political conservatives and liberals on (a) implicit family metaphors (G. Lakoff, 2002) and (b) moral intuitions (J. Haidt & C. Joseph, 2004). Content analysis of 12 key scenes in life stories showed that conservatives, as predicted, tended to depict authority figures as strict enforcers of moral rules and to identify lessons in self-discipline. By contrast, liberals were more likely to identify lessons learned regarding empathy and openness, even though (contrary to prediction) they were no more likely than conservatives to describe nurturant authority figures. Analysis of extended discourse on the development of religious faith and personal morality showed that conservatives emphasized moral intuitions regarding respect for social hierarchy, allegiance to in-groups, and the purity or sanctity of the self, whereas liberals invested more significance in moral intuitions regarding harm and fairness. The results are discussed in terms of the recent upsurge of interest among psychologists in political ideology and the value of using life-narrative methods and concepts to explore how politically active adults attempt to construct meaningful lives.
