Cognitive biases and emotion regulation (ER) difficulties have been instrumental in understanding hallmark features of depression. However, little is known about the interplay among these important risk factors to depression. This cross-sectional study investigated how multiple cognitive biases modulate the habitual use of ER processes and how ER habits subsequently regulate depressive symptoms. All participants first executed a computerised version of the scrambled sentences test (interpretation bias measure) while their eye movements were registered (attention bias measure) and then completed questionnaires assessing positive reappraisal, brooding, and depressive symptoms. Path and bootstrapping analyses supported both direct effects of cognitive biases on depressive symptoms and indirect effects via the use of brooding and via the use of reappraisal that was in turn related to the use of brooding. These findings help to formulate a better understanding of how cognitive biases and ER habits interact to maintain depressive symptoms. 相似文献
Two minimal group studies (Ns = 150, 123) examined the impact of emotional empathy on the ethnic attitudes of 5 to 12-year old white Anglo-Australian children. Study 1 evaluated the relationship between empathy and attitudes towards a same (Anglo-Australian) versus different ethnicity (Pacific Islander) outgroup. A significant empathy × outgroup ethnicity interaction revealed that empathy was unrelated to the children's liking for the same ethnicity outgroup, but that liking for the different ethnicity outgroup increased as empathy increased. Study 2 examined the influence of empathy on attitudes towards the different ethnicity outgroup when the ingroup had a norm of inclusion versus exclusion. A significant empathy × group norm interaction revealed that empathy was unrelated to liking when the ingroup had a norm of exclusion, but that liking for the different ethnicity outgroup increased when the ingroup had a norm of inclusion. Implications of the findings for promoting children's positive attitudes to ethnic minority groups are discussed. 相似文献
The current studies used the Perceptions of Dating Infidelity Scale (PDIS), which identifies attitudes toward three types
of behaviors indicative of cheating: Ambiguous, Deceptive, and Explicit behaviors, to predict actual infidelity behaviors.
Participants reported their attitude toward these behaviors and then reported their willingness to engage in these behaviors
with a hypothetical target (Study 1) and reported actually engaging in these behaviors over the course of one month (Study
2). Study 1 showed that attitudes for Ambiguous and Deceptive behaviors significantly predict a willingness to engage in these
behaviors with a hypothetical target. Study 2 showed that attitudes toward Ambiguous behaviors significantly predict actual
engagement in Ambiguous behaviors during the course of one month. 相似文献
The capacity to reason about the false beliefs of others is classically considered the benchmark for a fully fledged understanding of the mental lives of others. Although much is known about the developmental origins of our understanding of others' beliefs, we still know much less about the evolutionary origins of this capacity. Here, we examine whether non-human primates - specifically, rhesus macaques (Macaca mulatta) - share this developmental achievement. We presented macaques with a looking-time measure of false belief understanding, one that had recently been developed for use with 15-month-old human infants. Like human infants, monkeys look longer when a human experimenter fails to search in the correct location when she has accurate knowledge. In contrast to infants, however, monkeys appear to make no prediction about how a human experimenter will act when she has a false belief. Across three studies, macaques' pattern of results is consistent with the view that monkeys can represent the knowledge and ignorance of others, but not their beliefs. The capacity to represent beliefs may therefore be a unique hallmark of human cognition. 相似文献
From a dynamic systems perspective, transition points in development are times of increased instability, during which behavioral patterns are susceptible to temporary decoupling. This study investigated the impact of the vocabulary spurt on existing patterns of communicative coordination. Eighteen typically developing infants were videotaped at home 1 month before, at, and after the vocabulary spurt. Infants were identified as spurters if they underwent a discrete phase transition in vocabulary development (marked by an inflection point), and compared with a group of nonspurters whose word-learning rates followed a trajectory of continuous change. Relative to surrounding sessions, there were significant reductions in overall coordination of communicative behaviors and in words produced in coordination at the vocabulary spurt session for infants who experienced more dramatic vocabulary growth. In contrast, nonspurters demonstrated little change across sessions. Findings underscore the importance of transitions as opportunities for observing processes of developmental change. 相似文献
Place learning abilities represent adaptations that contribute also to foraging efficiency under given spatio-temporal conditions.
We investigated if this ability in turn constrains decision making in two sympatric vole species: while the herbivorous common
vole (Microtus arvalis) feeds on spatio-temporally predictable food resources (e.g. roots, tubers and shoots of plant tubers), the omnivorous bank
vole (Myodes glareolus) additionally subsists on temporally unpredictable food resources (e.g. insects and seeds). Here, we compare the spatial
reference memory and working memory of the two species. In an automated operant home cage with eight water places, female
voles either had to learn the fixed position of non-depletable places (reference memory task) or learn and avoid previously
visited water places depleted in a single visit (win-shift task). In the reference memory task, Microtus females required significantly more choices to find all water places, initially performed slightly worse than Myodes females, and displayed slightly lower asymptotic performance. Both species were highly similar in new learning of the same
task. In the more complex win-shift task, asymptotic performance was significantly lower in Microtus (72% correct) than in Myodes (79%). Our results suggest that both vole species resemble each other in their efficiency to exploit habitats with low spatio-temporal
complexity but may differ in their efficiency at exploiting habitats with temporally changing spatial food distributions.
The results imply that spatial ability adjusted to specific food distributions may impair flexible use of habitats that differ
in their food distribution and therefore, decrease a species’ chances of survival in highly dynamic environments. 相似文献
Li Zehou belongs among the ranks of the most important Chinese philosophers of the 20th and 21st centuries. In his complex theoretical system, he aimed to reconcile the Chinese cultural heritage with the demands of the contemporary world. Besides elaborating on traditional Chinese philosophy, Li launched many innovative views based on his understanding of specific developments in pre-modern and modern Western philosophy. His philosophy could be described as the search for a synthesis between Western and traditional Chinese thought and a specifically Chinese modernization. In order to provide a basic insight into Li’s specific methods of combining Kant, early Marx and classical Chinese philosophy, the present article investigates his elaboration of the traditional Chinese paradigm of “the unity of nature and man” (tianren heyi天人合一) through the lens of ideas about humanized nature (renhua de ziran人化的自然) and naturalized humans (ziranhua de ren自然化的人). 相似文献
Many college students experience difficulties in basic academic skills. Recent research suggests that much of this difficulty may lie in heuristic competency--the ability to use and successfully manage general cognitive strategies. In the present study, the authors evaluated this possibility. They compared participants' performance on a practice California Basic Educational Skills Test and on a series of questions in the natural sciences with heuristic and algorithmic performance on a series of mathematics and reading comprehension exercises. Heuristic competency in mathematics was associated with better scores in science and mathematics. Verbal and algorithmic skills were associated with better reading comprehension. These results indicate the importance of including heuristic training in educational contexts and highlight the importance of a relatively domain-specific approach to questions of cognition in higher education. 相似文献
In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-192 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of wakefulness. Overall, standardized response speed scores on the 5-min PDA-PVT closely tracked those of the PVT-192; however, the PDA-PVT was generally associated with more lapses/minute. Closer inspection of the data indicated that when the level of sleep loss and fatigue became more severe (i.e., Day 3), the 5-min PDA-PVT was not quite as sensitive as the 10-min PVT-192 when 2- to 10-sec foreperiods were used for both. It is likely, however, that the observed differences between the two devices was due to differences in task length. Thus, the findings provide further evidence of the validity of the 5-min PDA-PVT as a substitute for the 10-min PVT-192, particularly in circumstances in which a shorter test is required and/or the PVT-192 is not as practical. 相似文献
This paper illustrates how and when the personality characteristics of a political leader can initiate and/or become intertwined with societal and political processes. We are not suggesting that “real world” issues and secondary process calculations are not important or should be discarded in favor of psychological considerations. Instead, we suggest that psychoanalysts and psychodynamically informed mental health professionals can contribute to a more complete analysis of political or societal processes and the personalities of leaders who play major roles in them. Only through such interdisciplinary work can we fully understand the complex and intertwined nature of the crucial events that shape political leaders’ internal and external worlds.
