Faces are one of the most significant social stimuli and the processes underlying face perception are at the intersection
of cognition, affect, and motivation. Vision scientists have had a tremendous success of mapping the regions for perceptual
analysis of faces in posterior cortex. Based on evidence from (a) single unit recording studies in monkeys and humans; (b)
human functional localizer studies; and (c) meta-analyses of neuroimaging studies, I argue that faces automatically evoke
responses not only in these regions but also in the amygdala. I also argue that (a) a key property of faces represented in
the amygdala is their typicality; and (b) one of the functions of the amygdala is to bias attention to atypical faces, which
are associated with higher uncertainty. This framework is consistent with a number of other amygdala findings not involving
faces, suggesting a general account for the role of the amygdala in perception. 相似文献

The primary aim of this research was to investigate associations that depression severity and trait anxiety have with reactions to specific, identifiable thoughts experienced by persons with varying levels of personality disorder (PD) pathology as they went about their day-to-day lives. Ninety-eight psychotropic medication-free persons participated in an experience sampling assessment procedure over four consecutive days, during which participants recorded specific thoughts experienced moments before a page signal was received and corresponding ratings of thought discomfort. Thought discomfort, regarded as an emotional reaction to thoughts or their evaluation, was moderately associated with several forms of PD pathology, particularly Cluster C pathology. Once depression severity and trait anxiety were controlled, however, associations between PD pathology and thought discomfort were eliminated. Findings from this research generally support the mood-congruence of negatively valenced thoughts in relation to PD pathology. 相似文献

The stereotype content model (SCM) posits that warmth and competence are the key components underlying judgments about social groups. Because competence can encompass different components (e.g., intelligence, talent) different group members may be perceived to be competent for different reasons. Therefore, we believe it may be important to specify the type of competence being assessed when examining perceptions of groups that are positively stereotyped (i.e., Black athletes and musical Blacks). Consistent with the SCM, these subgroups were perceived as high in competence-talent but not in competence-intelligence and low in warmth. Both the intelligence and talent frame of competence fit in the SCM's social structural hypothesis. 相似文献

Rats were able to search multiple food cups in a foraging task and successfully return to a fixed, but not a variable, start location. Reducing the number of food cups to be searched resulted in an improvement in performance in the variable start condition. Performance was better when only one or two food cups had to be visited but was still impaired if the food was not found in the first cup searched. Variable start locations impaired performance when only one food cup had to be searched, if that cup was moved over the table. These findings suggest that there is an interaction between memory processes and the navigational processes that allows an animal to return to its start location after a foraging trip. It appears that a fixed location for the food or the start point of a foraging trip is a necessary precondition for accurate performance. 相似文献

Internalism about a person’s good is roughly the view that in order for something to intrinsically enhance a person’s well-being,
that person must be capable of caring about that thing. I argue in this paper that internalism about a person’s good should
not be believed. Though many philosophers accept the view, Connie Rosati provides the most comprehensive case in favor of
it. Her defense of the view consists mainly in offering five independent arguments to think that at least some form of internalism
about one’s good is true. But I argue that, on closer inspection, not one of these arguments succeeds. The problems don’t
end there, however. While Rosati offers good reasons to think that what she calls ‘two-tier internalism’ would be the best
way to formulate the intuition behind internalism about one’s good, I argue that two-tier internalism is actually false. In
particular, the problem is that no substantive theory of well-being is consistent with two-tier internalism. Accordingly,
there is reason to think that even the best version of internalism about one’s good is in fact false. Thus, I conclude, the
prospects for internalism about a person’s good do not look promising. 相似文献

In three experiments, we used face–name learning to examine the puzzling feedback delay benefit—the tendency for feedback to be more effective when it is delayed rather than presented immediately. In Experiment 1, we found that feedback presented after a 3-s blank screen was more effective than feedback presented immediately, even after
controlling for the exposure time to the material. In Experiment 2, we replicated the benefit of a feedback delay even when participants were given extra time to view the feedback or to try
to retrieve the answer, indicating that this benefit is specific to a delay before feedback. Finally, in Experiment 3, we showed that the 3-s delay is beneficial only if it involves a blank screen, not if the delay is filled with an unrelated
distracter task. These results suggest that the feedback delay benefit in this paradigm could arise from an active anticipatory
process that occurs during the delay. 相似文献

Context effects in category rating on a 7-point scale are shown to reverse direction depending on feedback. Context (skewed stimulus frequencies) was manipulated between and feedback within subjects in two experiments. The diverging predictions of prototype- and exemplar-based scaling theories were tested using two representative models: ANCHOR and INST. To gain coverage on one side of the continuum, a prototype-based category must lose on the opposite side. ANCHOR can exhibit both assimilative and compensatory context effects depending on feedback. INST always exhibits assimilative effects. The human data show a significant context-by-feedback interaction. The main context effect is assimilative in one data set and compensatory in the other. This pattern is consistent with ANCHOR but rules out INST, which fails to account for the compensatory effect and the interaction. This suggests that human category rating is based on unitary representations. 相似文献

Previous research has shown that body postures and body movements influence people’s attitudes, preferences and feelings. In the present study, we explored the influence of body posture on the feeling of closeness towards others and how this effect may interact with contextual variables. Study 1 was conducted in a naturalistic setting in which 127 participants observed a series of live dance sequences either standing up or remaining seated. After each sequence, participants reported the feelings elicited by the dance performance on a questionnaire. Visibility of performers’ facial expressions and background tempo were used as contextual variables. Results showed that participants who watched the performance standing up felt significantly closer to the dancers than participants who remained seated. Study 2 was carried out in a laboratory setting to explore the relationship between body posture, tempo and heart rate. Results showed a significant increase in heart rate when standing compared to when sitting and no effect of tempo. The present research demonstrates a link between body posture and social connection providing evidence that standing up strengthens the feeling of closeness to others, and showing that posture not only has an impact on self-related feelings (e.g. fear, anger, sadness) as previous research has shown, but also has an impact on feelings towards others at the base of all human social relations. The present research also suggests that heart rate may be a mediator of the effect of posture on the feeling of closeness. 相似文献
