It has been found that emotional pictures are estimated to last longer than neutral ones. However, emotional and neutral stimuli often differ in their physical characteristics, too. Since this might also affect time perception, we present a method disentangling a possible confounding regarding the processing of physically different stimulus material. In the evaluative condition paradigm, participants, at first, learnt the association of neutral images with a certain Landolt ring and of emotional images with another Landolt ring with a different gap position. The conditioned Landolt rings were subsequently used in a temporal bisection task. In two experiments, the results revealed a temporal overestimation of Landolt rings conditioned with emotional pictures compared to neutral pictures showing that the temporal overestimation of emotional stimuli cannot be attributed to perceptual differences between neutral and emotional stimuli. The method provides the potential for investigating emotional effects on various perceptual processes. 相似文献

This study investigated whether direct and indirect measures predict unique variance components of fearful behaviour in children. One hundred eighty-nine children aged between 9 and 12 performed a pictorial version of the emotional Stroop task (EST), filled out the Spider Anxiety and Disgust Screening for Children (SADS-C), the Spider Phobia Questionnaire for Children (SPQ-C), and took part in a Behavioural Assessment Test (BAT). The EST did not correlate with self-reports. Correlations of the self-reports and the BAT remained significant after partialling out EST performance. Likewise, the EST and the BAT still correlated significantly with each other when controlling for the self-reports. This indicates that both direct and indirect measures are useful for predicting unique variance components of fearful behaviour in children. Moreover, it may explain why some previous studies have not found a relationship between self-reported fear and EST performance. 相似文献

A depressogenic attributional style, i.e., internal, stable and global causal interpretations of negative events, is a stable
vulnerability factor for depression. Current measures of pessimistic attributional style can be time-consuming to complete,
and some are designed for specific use with student populations. We developed and validated a new short questionnaire suitable
for the measurement of depressogenic attributions in clinical settings, the Depressive Attributions Questionnaire (DAQ). The
16-item DAQ, and measures of depression and related cognitive concepts were completed by three samples of depressed patients
and matched controls, or depressed and non-depressed participants who had been exposed to a recent uncontrollable stressful
life event (total N = 375). The DAQ had high (i) internal reliability, (ii) test-retest reliability, (iii) convergent, discriminant and construct
validity. It predicted a diagnosis of major depression at 6 months after an uncontrollable stressor, over and above what could
be predicted from initial depression severity. Depressed patients rated the scale as acceptable. The DAQ may be a useful short
measure of depressogenic attributions, which is easy to administer, and predicts concurrent and future depression. It has
possible applications as a screening measure for risk of depression, or as a treatment process measure. 相似文献

There is preliminary evidence that enhanced priming for trauma-related cues plays a role in posttraumatic stress disorder (PTSD). A prospective study of 119 motor vehicle accident survivors investigated whether priming for trauma-related stimuli predicts PTSD. Participants completed a modified word-stem completion test comprising accident-related, traffic-related, general threat, and neutral words at 2 weeks post-trauma. Priming for accident-related words predicted PTSD at 6 months follow-up, even when initial symptom levels of PTSD and depression and priming for other words were controlled. The results are in line with the hypothesis that enhanced priming for traumatic material contributes to the development of chronic PTSD. 相似文献

Both chimpanzees and human infants use the pointing gesture with human adults, but it is not clear if they are doing so for the same social motives. In two studies, we presented chimpanzees and human 25-month-olds with the opportunity to point for a hidden tool (in the presence of a non-functional distractor). In one condition it was clear that the tool would be used to retrieve a reward for the pointing subject (so the pointing was selfish or 'for-me'), whereas in the other condition it was clear that the tool would be used to retrieve the reward for the experimenter (so the pointing was helpful or 'for-you'). The chimpanzees pointed reliably only when they themselves benefited, whereas the human children pointed reliably no matter who benefited. These results are interpreted as evidence for the especially cooperative nature of human communication. 相似文献

This study explored the effects of oxytocin on Compassion Focused Imagery (CFI), that is, imagining another "mind" being deeply compassionate to oneself, and the interaction of these effects with self-criticism and feeling socially safe with others. Forty-four healthy participants (29 men and 15 women) completed self-report measures of self-criticism, attachment style, and social safeness before taking part in a double-blind randomized placebo controlled study. They attended two imagery sessions, receiving oxytocin in one and a placebo in the other. Positive affect was measured before and after each imagery session, and "imagery experience" was assessed after each session. Overall, oxytocin increased the ease of imagining compassionate qualities but there were important individual differences in how CFI was experienced. Participants higher in self-criticism, lower in self-reassurance, social safeness, and attachment security had less positive experiences of CFI under oxytocin than placebo, indicating that the effects of oxytocin on affiliation may depend on attachment and self-evaluative styles. 相似文献

Previous studies using adult observers are inconsistent with regard to social skills deficits in nonclinical socially anxious
youth. The present study investigated whether same age peers perceive a lack of social skills in the socially anxious. Twenty
high and 20 low socially anxious adolescents (13–17 years old) were recorded giving a 5-min speech. Unfamiliar peer observers
(12–17 years old) viewed the speech samples and rated four social skills: speech content, facial expressions, posture and
body movement, and way of speaking. Peer observers perceived high socially anxious adolescents as significantly poorer than
low socially anxious adolescents on all four social skills. Moreover, for all skills except facial expressions, group differences
could not be attributed to adolescents’ self-reported level of depression. We suggest that therapists take the perceptions
of same age peers into account when assessing the social skills of socially anxious youth. 相似文献

To study the question of which processes contribute to crowding and whether these are comparable to those of visual temporal masking, we varied the stimulus onset asynchrony (SOA) between target and flankers in a crowding setting. Monotonically increasing Type A masking functions observedfor small spacings and large eccentricities indicate that the integration of information from target and flankers underlies crowding. Decreasing masking functions obtained for large spacings and small eccentricities relate processes of crowding to those contributing to Type B masking. In addition, Type B masking was more frequent with letter-like nonletter flankers than with letter flankers, suggesting that Type B masking, just like crowding over large areas, is due to higher level interactions. The rapid decrease of the effects of interletter spacing and eccentricity with increasing SOA indicates that positional information is transient. 相似文献
