In the present study we examined the neural correlates of facial emotion processing in the first year of life using ERP measures and cortical source analysis. EEG data were collected cross‐sectionally from 5‐ (N = 49), 7‐ (N = 50), and 12‐month‐old (N = 51) infants while they were viewing images of angry, fearful, and happy faces. The N290 component was found to be larger in amplitude in response to fearful and happy than angry faces in all posterior clusters and showed largest response to fear than the other two emotions only over the right occipital area. The P400 and Nc components were found to be larger in amplitude in response to angry than happy and fearful faces over central and frontal scalp. Cortical source analysis of the N290 component revealed greater cortical activation in the right fusiform face area in response to fearful faces. This effect started to emerge at 5 months and became well established at 7 months, but it disappeared at 12 months. The P400 and Nc components were primarily localized to the PCC/Precuneus where heightened responses to angry faces were observed. The current results suggest the detection of a fearful face in infants’ brain can happen shortly (~200–290 ms) after the stimulus onset, and this process may rely on the face network and develop substantially between 5 to 7 months of age. The current findings also suggest the differential processing of angry faces occurred later in the P400/Nc time window, which recruits the PCC/Precuneus and is associated with the allocation of infants’ attention. 相似文献

Recently there has been growing interest among psychologists in human performance on the Euclidean traveling salesperson problem (E-TSP). A debate has been initiated on what strategy people use in solving visually presented E-TSP instances. The most prominent hypothesis is the convex-hull hypothesis, originally proposed by MacGregor and Ormerod (1996). We argue that, in the literature so far, there is no evidence for this hypothesis. Alternatively we propose and motivate the hypothesis that people aim at avoiding crossings. 相似文献

The current study examined how dimensions of masculinity and femininity were expressed for sexual minorities. Cluster analysis was used to determine the number of latent classes for conformity to masculine and feminine norms for sexual minorities. A four-class solution was the best fit to the data. Cluster 1 (labeled Relating to others through equality and caring, n = 41) was characterized by low dominance and power over women and high involvement with kids and have nice relationships norms. Cluster 2 (labeled Relating to others through avoidance and misogyny, n = 38) was characterized by low risk-taking and have nice relationships and high power over women and disdain for homosexuality. Cluster 3 (labeled Relating to others through power, n = 34) was characterized by high winning, pursuit of status, and appearance and low modesty. Cluster 4 (labeled Relating to others through sex, n = 27) was characterized by low involvement in romantic relationships and sexual fidelity while endorsing high playboy attitudes. Results indicate that conforming to gender norms tends to follow categories of interpersonal beliefs and behaviors rather than being based in gender identity or sexual orientation. Implications of the results for future research and clinical practice are examined. 相似文献

ABSTRACT— Many studies have established that 2-month-old infants have knowledge of solid objects' basic physical properties. Evidence about infants' understanding of nonsolid substances, however, is relatively sparse and equivocal. We present two experiments demonstrating that 5-month-old infants have distinct expectations for how solids and liquids behave. Experiment 1 showed that infants use the motion cues from the surface of a contained liquid or solid to predict whether it will pour or tumble from a cup if the cup is upended. Experiment 2 extended these findings to show that motion cues lead to distinct expectations about whether a new object will pass through or remain on top of a substance. Together, these experiments demonstrate that 5-month-old infants are able to use movement cues and solidity to discriminate a liquid from an object of similar appearance, providing the earliest evidence that infants can reason about nonsolid substances. 相似文献

Based on social–functional accounts of emotion, we conducted two studies examining whether the degree to which people smiled
in photographs predicts the likelihood of divorce. Along with other theorists, we posited that smiling behavior in photographs
is potentially indicative of underlying emotional dispositions that have direct and indirect life consequences. In the first
study, we examined participants’ positive expressive behavior in college yearbook photos and in Study 2 we examined a variety
of participants’ photos from childhood through early adulthood. In both studies, divorce was predicted by the degree to which
subjects smiled in their photos.

Attachment theory, as a developmentally based theory of personality formation, provides a viable framework for understanding the development and maintenance of personality disorders, or what A. E. Ivey and M. B. Ivey (1998) have referred to as “developmental personality styles.” Using K. Bartholomew's (1990) 4‐dimensional model of adult attachment as an organizational framework, 10 developmental personality styles are differentiated regarding their unique attachment experiences, working models of self and other, and feedforward beliefs. Implications of an attachment theory framework for counseling clients with problematic developmental personality styles are discussed. 相似文献

Previous research has found concurrent and prospective associations between negative mood and body dissatisfaction; however, only experimental research can establish causal relationships. This study utilized an experimental design to examine the influence of negative mood on body dissatisfaction. Undergraduate women were randomly assigned to an experimental or control condition. Participants in the experimental condition (n=21) completed a negative mood induction procedure. Participants in the control condition (n=24) completed a neutral mood procedure. All participants completed visual analog scales regarding their mood and satisfaction with weight and shape before and after each manipulation. Body dissatisfaction increased following the procedure for experimental but not control participants, suggesting that negative mood caused increased body dissatisfaction. In cultures that idealize thinness, body dissatisfaction may arise from funneling general feelings of dysphoria into more concrete and culturally meaningful negative feelings about the body. 相似文献
