We examined variations in maternal sensitivity at 6 months of child age as a function of child negativity and maternal physiology. We expected maternal vagal withdrawal in response to infant negative affect to facilitate the maintenance of sensitivity, but only for mothers of securely attached children. One hundred and forty-eight infant-mother dyads were observed in multiple contexts at 6 months of child age, and associations among maternal and child variables were examined with respect to 12-month attachment quality. Mothers of later securely attached children were more sensitive than mothers of avoidant children. However, sensitivity decreased for all mothers at high levels of infant negative affect. Furthermore, for mothers of avoidant children, vagal withdrawal was associated with sensitivity to child distress. No association was found between vagal withdrawal and sensitivity for mothers of securely attached children. This suggests that mothers of avoidant children may be uniquely challenged by the affective demands of their infants. 相似文献

The present study investigates whether knowledge about the intentional relationship between gesture and speech influences controlled processes when integrating the two modalities at comprehension. Thirty-five adults watched short videos of gesture and speech that conveyed semantically congruous and incongruous information. In half of the videos, participants were told that the two modalities were intentionally coupled (i.e., produced by the same communicator), and in the other half, they were told that the two modalities were not intentionally coupled (i.e., produced by different communicators). When participants knew that the same communicator produced the speech and gesture, there was a larger bi-lateral frontal and central N400 effect to words that were semantically incongruous versus congruous with gesture. However, when participants knew that different communicators produced the speech and gesture--that is, when gesture and speech were not intentionally meant to go together--the N400 effect was present only in right-hemisphere frontal regions. The results demonstrate that pragmatic knowledge about the intentional relationship between gesture and speech modulates controlled neural processes during the integration of the two modalities. 相似文献

Using a radial maze analog task, T. R. Zentall, J. N. Steirn, and P. Jackson-Smith (1990) found evidence that when a delay was interpolated early in a trial, pigeons coded locations retrospectively, but when the delay was interpolated late in the trial, they coded locations prospectively (support for a dual coding hypothesis). In Experiment 1 of the present study, the authors replicated the original finding of dual coding. In Experiments 2 and 3, they used a 2-alternative test procedure that does not require the assumption that pigeons' choice criterion, which changes over the course of the trial, is the same on delay and control trials. Under these conditions, the pigeons no longer showed evidence for dual coding. Instead, there was some evidence that they showed prospective coding, but a more parsimonious account of the results may be that the delay produced a relatively constant decrement in performance at all points of delay interpolation. The original finding of dual coding by Zentall et al. might have been biased by more impulsive choices early in control trials but not in delay trials and by a more stringent choice criterion late in delay trials. 相似文献

This study examined generational differences in gender attitudes between parents and grown offspring, including the extent to which these differences vary in families with daughters vs families with sons and in African American vs European American families. Participants included 158 African American and European American men and women (aged 22 to 49 years), their mothers, and their fathers (N?=?474) recruited predominantly through purchased telephone lists. Participants completed a self-report measure of gender attitudes toward marital and childrearing roles. Mixed method ANOVAs revealed offspring were less traditional than parents, although there were greater generational differences in attitudes between mothers and daughters and in European American families. Findings are discussed in terms of implications for family roles and relationships. 相似文献

This study compared rates of self-reported childhood maltreatment in three groups diagnosed using semi-structured interviews: binge eating disorder (BED; n=176), night eating syndrome (NES, n=57), and overweight/obese comparison (OC, n=38). We used the Childhood Trauma Questionnaire (CTQ) to assess childhood maltreatment and the Beck Depression Inventory-II to assess depression levels. Reports of maltreatment were common in patients with BED (82%), NES (79%), and OC (71%). The BED group reported significantly more forms of maltreatment above clinical cut-points (2.4) than the OC (1.4) group but not the NES (1.8) group. The BED and NES groups reported more emotional abuse than the OC group. A higher proportion of the BED group reported emotional neglect and a higher proportion of the NES group reported physical neglect. Depression levels, which were higher in BED and NES than OC, were associated with higher levels of physical and emotional abuse and neglect. In conclusion, reported rates of physical and sexual abuse differed little across groups, whereas reports of neglect and emotional abuse were higher in the BED and NES groups than in the OC group and were associated with elevated depression levels. 相似文献

A number of studies have demonstrated that recovery from depression is often marked by precipitous improvements during the course of treatment. The present research examined sudden gains occurring outside of the context of treatment in a sample of college students with current major depressive disorder (n=60), and tested whether variables pertaining to cognitive style, hope, self-evaluation, and life events would be associated with these gains. Results indicated that 60% of the sample experienced sudden gains, with over half of those sudden gains reversing before the end of the 9-week observation period. Sudden gainers were significantly less depressed at the end of the observation period but were no more likely to have achieved remission compared to non-sudden gainers. Although changes in cognitive style did not precede sudden gains, individuals with sudden gains had significantly higher self-esteem at baseline compared to non-sudden gainers. Furthermore, decreases in the frequency of social comparison occurred in the week prior to sudden gains. These results suggest that sudden gains do occur outside of the context of treatment and that self-evaluation processes may play an important role in recovery from depression. 相似文献

The present study evaluated sex differences in observational fear conditioning using modeled “mock” panic attacks as an unconditioned stimulus (UCS). Fifty-nine carefully prescreened healthy undergraduate participants (30 women) underwent 3 consecutive differential conditioning phases: habituation, acquisition, and extinction. It was expected that participants watching a confederate display mock panic attacks (UCS) paired with a previously neutral stimulus (CS+) would learn to respond fearfully to the CS+, but not to the CS− (i.e., a stimulus never associated with displays of panic). Women also were expected to report more distress and ratings of panic to the CS+ than the CS− compared to men, but no sex differences were anticipated on autonomic indices of conditioning (i.e., electrodermal responses). Consistent with expectation, aversive conditioning was demonstrated by greater magnitude electrodermal and verbal-evaluative (e.g., subjective units of distress scale, panic ratings) responses to the CS+ over the CS−, with women reporting more distress to the CS+ over the CS−, but not greater autonomic conditioning, compared to men. Overall, the results support the notion that modeled panic attacks can serve as a potent UCS for both men and women. Discussion focuses on sex differences in observational fear conditioning and its relation to the clinical presentation of anxiety disorders. 相似文献

Fjellstedt and Sulzer-Azaroff (1973) used differential reinforcement of short latencies to decrease a child's latency to comply with instructions. We replicated this contingency with a young man diagnosed with Asperger syndrome across two tasks (question answering and math problem solving). We added a differential reinforcement contingency to teach the participant to discriminate between math problems that could be answered rapidly and those that required more time for accurate performance. 相似文献

The importance of intellectual talent to achievement in all professional domains is well established, but less is known about other individual differences that predict success. The authors tested the importance of 1 noncognitive trait: grit. Defined as perseverance and passion for long-term goals, grit accounted for an average of 4% of the variance in success outcomes, including educational attainment among 2 samples of adults (N=1,545 and N=690), grade point average among Ivy League undergraduates (N=138), retention in 2 classes of United States Military Academy, West Point, cadets (N=1,218 and N=1,308), and ranking in the National Spelling Bee (N=175). Grit did not relate positively to IQ but was highly correlated with Big Five Conscientiousness. Grit nonetheless demonstrated incremental predictive validity of success measures over and beyond IQ and conscientiousness. Collectively, these findings suggest that the achievement of difficult goals entails not only talent but also the sustained and focused application of talent over time. 相似文献

The present study examined the relations among sex, work-family conflict, and psychological distress in 78 Canadian police officers (50 men and 28 women). The average age of the officers was 36.1 yr. (SD=8.0), and nearly one-third of the respondents had been in policing 16 years or more. Ordinary least-squares regression was conducted to examine the association of Psychological Distress scores, as measured by the K6, with four types of work-family conflict: Time-based Work-to-Family Conflict, Time-based Family-to-Work Conflict, Strain-based Work-to-Family Conflict, and Strain-based Family-to-Work Conflict. Being single and having higher perceived Strain-based Work-to-Family Conflict were associated with greater scores on Psychological Distress. No statistically significant sex differences emerged in the self-reported type or direction of work-family conflict or in the factors associated with Psychological Distress. 相似文献
