Although infants display preferences for social stimuli early in their lives, we know relatively little about the mechanisms of infant learning about the social world. In the current set of studies, 1-month-old infants underwent an adapted eyeblink conditioning paradigm to examine learning to both 'social' and non-social cues. While infants were asleep, they were presented with either a 'social' stimulus (a female voice) or one of two non-social stimuli (tone or backward voice) followed by an airpuff presented to the eyelid. Infants in the experimental groups displayed increased learning across trials, regardless of stimulus type. However, infants conditioned to the 'social' stimulus showed increased learning compared to infants conditioned to either of the non-social stimuli. These results suggest a mechanism by which learning about the social world occurs early in life and the power of ecologically valid cues in facilitating that learning. 相似文献

Nine experiments tested competing hypotheses regarding nonconscious affective responses to acute social exclusion and how such responses may relate to positive mental health. The results strongly and consistently indicated that acute social exclusion increased nonconscious positive affect. Compared to nonexcluded participants, excluded participants recalled more positive memories from childhood than did accepted participants (Experiment 1), gave greater weight to positive emotion in their judgments of word similarity (Experiments 2 and 3), and completed more ambiguous word stems with happy words (Experiments 4a and 4b). This process was apparently automatic, as participants asked to imagine exclusion overestimated explicit distress and underestimated implicit positivity (Experiment 3). Four final experiments showed that this automatic emotion regulation process was found among participants low (but not high) in depressive symptoms (Experiments 5 and 6) and among participants high (but not low) in self-esteem (Experiments 7 and 8). These findings suggest that acute exclusion sets in motion an automatic emotion regulation process in which positive emotions become highly accessible, which relates to positive mental health. 相似文献

Objective
Use classification tree analysis with lagged predictors to determine empirically derived cut-points for identifying adolescent girls at risk for future onset of threshold, subthreshold, and partial eating disorders and test for interactions between risk factors that may implicate qualitatively distinct risk pathways.Method
Data were drawn from a prospective study of 496 adolescent girls who completed diagnostic interviews and surveys annually for 8 years.Results
Body dissatisfaction emerged as the most potent predictor; adolescent girls in the upper 24% of body dissatisfaction showed a 4.0-fold increased incidence of eating disorder onset (24% vs. 6%). Among participants in the high body dissatisfaction branch, those in the upper 32% of depressive symptoms showed a 2.9-fold increased incidence of onset (43% vs. 15%). Among participants in the low body dissatisfaction branch, those in the upper 12% of dieting showed a 3.6-fold increased incidence onset (18% vs. 5%).Conclusion
This three-way interaction suggests a body dissatisfaction pathway to eating disorder onset that is amplified by depressive symptoms, as well as a pathway characterized by self-reported dieting among young women who are more satisfied with their bodies. It may be possible to increase the effectiveness of prevention programs by targeting each of these qualitatively distinct risk groups, rather than only individuals with a single risk factor. 相似文献164.

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age. 相似文献

The focus of this study is on everyday positive emotions and their relations to critical appraisal antecedents. Following
from classical appraisal theory and Pekrun’s (2006) control-value theory of achievement emotions, two research questions were addressed, namely whether cognitive appraisals
of control and value were related to discrete positive emotions in everyday situations and whether control and value antecedents
interact in predicting these emotions. We further investigated whether control/value and positive emotion relations changed
as a function of situational factors (achievement vs. non-achievement settings). 50 university freshmen (78% female) were
assessed by use of the experience sampling method for a period of 1 week, with intraindividual analyses conducted using a
multilevel, idiographic approach. Consistent with our hypotheses, the emotions of enjoyment, pride, and contentment were positively
related to control and value appraisals. Further, control and value interacted to predict these positive emotions. The strength
of appraisal/positive emotion relations was equivalent across achievement vs. non-achievement settings. Implications for future
research are discussed. 相似文献

Recent reports from electrophysiological and psychophysical experiments provide evidence that repeated exposure to an ordered sequence of morphed stimuli may over time adapt a prelearned object category such that the category may generalise the entire sequence as belonging to the same object. Here, a new protocol that includes a single exposure to a morphing sequence is presented. Subjects exposed to the new protocol replaced a prelearned face with an entirely different face within just 3 days, significantly faster than in previous reports. 相似文献

Organization‐based self‐esteem (OBSE), which represents employees' beliefs about their own value and competence as organizational members, has attracted much recent research attention. In the current paper, we identified several theoretically based predictors and consequences of OBSE. We then conducted a meta‐analysis examining the relationships between OBSE and these variables. Results indicated that several hypothesized predictors, including the work environment and employee dispositions, were related to OBSE. Furthermore, OBSE was related to several hypothesized outcome variables including job satisfaction, organizational commitment, employee health, job performance, and organizational citizenship behaviour. As expected, OBSE generally yielded stronger relationships with work‐related variables than did general self‐esteem and we found evidence that OBSE mediated the relationships between general self‐esteem and work‐related criteria. 相似文献

Eyewitnesses sometimes view more than one lineup during an investigation. We investigated the effects of postidentification feedback following one lineup on responses to a second lineup. Witnesses (N=621) viewed a mock crime and, later, attempted to identify the culprit from an initial (target-absent) lineup and a second (target-present or target-absent) lineup. Prior to viewing the second lineup, some witnesses received accurate feedback stating that the initial lineup did not contain the culprit. A compound-decision, signal detection approach allowed the effects of feedback on identification responses to be described in terms of differences in discriminability and response bias. For witnesses who made an incorrect foil identification from the initial lineup, feedback (vs. no feedback) was associated with poorer discriminability on the second test. For witnesses who correctly rejected the initial lineup, feedback (vs. no feedback) was associated with greater discriminability on the second test. Only witnesses who received feedback after an initial correct rejection performed at a level comparable with a single-lineup control group, suggesting that an initial identification test can impair, but not enhance, performance on a second test involving the same culprit. From a theoretical perspective, the results are consistent with the idea that the way people use memorial information when making memory decisions is flexible. Analyses of preidentification confidence ratings, obtained in a follow-up study (N=133), suggested that the effects of feedback on identification performance may have operated via differences in witnesses' metacognitive beliefs. 相似文献
