Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the object, the protagonist pointed either at the correct location or at the incorrect location. Across experiments, 18-month-olds looked longer at the unexpected action (e.g., person pointing at the incorrect location in the Visual Access condition). By 24 month of age, infants could infer the correct search behavior from gaze alone. These findings suggest that by the middle of the second year of life, infants understand the psychological relation between an observer and an object, even if the object is no longer visible. 相似文献

This study of 93 men and 117 women smokers during an ongoing quit attempt examined the roles of gender and social network influences on quitting. For men, social influences appeared to positively affect their ability to reduce their smoking but were less effective for women. Specifically, increased reports of a spouse or partner's influence, and family and friends' influence, were associated with greater reductions in men's smoking 2 days and 4 months post quit date, respectively. In contrast, for women, greater reports of spouse or partner influence and of family and friends' influence were associated with smaller reductions in smoking. Sex differences in social control strategies and perceived autonomy supportiveness of those strategies are discussed as possible explanations for these results. 相似文献

We report two experiments that investigate the calculating strategy used by a low IQ savant to identify prime numbers. Hermelin and O'Connor (1990) had suggested previously that this subject may use a procedure first described by Eratosthenes to detect a prime number, namely, dividing a target number by all primes up to the square root of the target number and testing for a remainder. In the first experiment, we compare the reaction times of the savant to decide whether a number is prime with those of a control subject proficient in mathematical calculation. In addition, we measured the savant's speed of information processing using an inspection time task. We found that the reaction times of the savant, although generally faster, followed the same pattern of the control subject who reported using the Eratosthenes procedure. The savant's inspection time indicated that his speed of processing was far superior to that expected from someone of his IQ. In the second experiment, we measured the time it takes mathematics students to divide by different prime numbers and we also tested them on the prime identification task. We used their division times to simulate their performance on the prime number identification task under the assumption that they used the Eratosthenes procedure. We also simulated the reaction times that would result from a simple memory-based procedure for identifying primes. We found that the Eratosthenes simulation, in contrast to the memory simulation, provided a good fit to both the students' and the savant's reaction times. We conclude that the savant is using a complex computational algorithm to identify primes and suggest two explanations of how the apparent contradiction between his low general intelligence and his superior numerical ability might be resolved. 相似文献

Communication between parents and their children represents an important factor of family socialization. Nevertheless, little is known about why parents communicate in different ways and how these qualitative differences in parent–child communication may affect the child. Building on self-determination theory, the present study focuses on motivational antecedents of need-supportive communication as a function of parental child-related beliefs (i.e., long-term goals that parents have set for their children’s future, and parental child-related behavior expectations in terms of parental dissatisfaction or satisfaction with child behavior). Moreover, the effect of perceived need-supportive communication on children’s prosocial behavior and (externalizing and internalizing) behavioral difficulties will be addressed. Three waves of data from 1125 mothers and adolescents aged between 10 and 17 years were analyzed using growth-curve modeling. We found linearly increasing trajectories in extrinsic parental goals for children and dissatisfaction with child behavior, and decreasing trajectories of need-supportive communication. Individual differences do not vary significantly over time. In addition, holding extrinsic parental goals for children positively predicts parents’ dissatisfaction with their child’s behavior and negatively predicts need-supportive communication. Parents’ dissatisfaction with their child’s behavior also contributes to decreasing need-supportive communication. As expected, need-supportive communication predicts prosocial behavior and externalizing behavioral difficulties. When need-supportive communication decreases over time, both externalizing and internalizing behavioral difficulties increase. Furthermore, the effect of mothers beliefs on adolescents socioemotional development was mediated through perceived mother’s communication quality. These results suggest that parental child-related beliefs are important motivational antecedents of parent–child communication that may prevent behavioral difficulties. 相似文献

Social-Emotional competencies evolve early in life. For example, early emotion regulation is learned primarily in the context of mother–child interaction, which may allow for maternal influences to shape children's social-emotional development. The aim of the current study was to longitudinally examine maternal determinants of children's early social-emotional development in a community-based sample of first-time mothers (N = 61, aged 22–39 years). Specifically, we used structural equation modeling to examine how maternal emotion regulation difficulties and subclinical depression directly and indirectly, through sensitivity and postnatal bonding, assessed at 6 to 8 months predicted child outcomes at 12 to 16 months. We found that mothers’ sensitivity predicted fewer social-emotional and behavioral problems and that stronger bonding predicted fewer problems and more social-emotional competencies. Emotion regulation difficulties were significantly associated with depressive symptoms; yet, when accounting for shared variances, both factors differentially predicted less positive child outcomes such that more difficulties indirectly, through poorer bonding, predicted greater delay in competencies, and more symptoms indirectly, through less sensitivity, predicted more problems. Current findings underline the significance of maternal factors impacting the quality of mother–child interaction for children's positive development. Potential implications for early prevention programs to support children who are otherwise at risk for negative emotional outcomes due to mothers’ emotional state postpartum are discussed. 相似文献

Distorted negative self-images and impressions appear to play a key role in maintaining Social Anxiety Disorder (SAD). In previous research, McManus et al. (2009) found that video feedback can help people undergoing cognitive therapy for SAD (CT-SAD) to develop a more realistic impression of how they appear to others, and this was associated with significant improvement in their social anxiety. In this paper we first present new data from 47 patients that confirms the value of video feedback. Ninety-eighty percent of the patients indicated that they came across more favorably than they had predicted after viewing a video of their social interactions. Significant reductions in social anxiety were observed during the following week and these reductions were larger than those observed after control periods. Comparison with our earlier data (McManus et al., 2009) suggests we may have improved the effectiveness of video feedback by refining and developing our procedures over time. The second part of the paper outlines our current strategies for maximizing the impact of video feedback. The strategies have evolved in order to help patients with SAD overcome a range of processing biases that could otherwise make it difficult for them to spot discrepancies between their negative self-imagery and the way they appear on video. 相似文献

According to the new mechanistic approach, an acting entity is at a lower mechanistic level than another acting entity if and only if the former is a component in the mechanism for the latter. Craver and Bechtel (Biol Philos 22(4):547–563, 2007. doi: 10.1007/s10539-006-9028-8) argue that a consequence of this view is that there cannot be causal interactions between acting entities at different mechanistic levels. Their main reason seems to be what I will call the Metaphysical Argument: things at different levels of a mechanism are related as part and whole; wholes and their parts cannot be related as cause and effect; hence, interlevel causation in mechanisms is impossible. I will analyze this argument in more detail and show under which conditions it is valid. This analysis will reveal that interlevel causation in mechanisms is indeed possible, if we take seriously the idea that the relata of the mechanistic level relation are acting entities and accept a slightly modified notion of a mechanistic level that is highly plausible in the light of the first clarification. 相似文献

Assessment of Score Dependability of the Wisconsin Schizotypy Scales Using Generalizability Analysis
Beate P. Winterstein John T. Willse Thomas R. Kwapil Paul J. Silvia 《Journal of psychopathology and behavioral assessment》2010,32(4):575-585
To investigate the reliability of the Wisconsin Schizotypy Scales, this study applied generalizability analysis with two college
student samples who completed the scales at two time points. The results indicated that the Revised Social Anhedonia Scale
had acceptable levels of score dependability, but that the score dependability for the other scales (the Physical Anhedonia
Scale, the Perceptual Aberration Scale, and the Magical Ideation Scale) was below an acceptable level of .80. The patterns
of variance components suggested that the scales’ items need improvement. Researchers can use the included tables to choose
the number of items and occasions needed to get dependable score interpretations. 相似文献

BACKGROUND: The developmental course of children with conduct disorder (CD) is heterogeneous. Especially children who exhibit symptoms early in their lifetimes are characterized by a negative outcome. Neurobiological aspects of CD have been investigated in these children but little is known about structural and functional brain aberrations. METHODS: We describe the developmental taxonomy of children with CD and focus on those with the early onset subtype. Structural MRI data of these children and antisocial adults are recapitulated. The impact of investigating neurobiological underpinnings of antisocial behavior and how this might contribute to future forensic and psychiatric assessments is discussed. RESULTS/ CONCLUSION: Children display similar structural aberrations of fronto-limbic structures to adults with antisocial behavior, and amygdala dysfunction might be closely related to dysregulated emotions. Though the investigation of biological factors in antisocial subjects has made great progress in recent years, today MRI is still a rather complex, expensive and indistinct method for forensic assessment. 相似文献
