The purpose of this study was to examine the moderating role of maternal sensitivity on the association between prenatal adversity and externalizing behaviors at 24 months of age in a diverse, high-risk sample. We hypothesized that among children with higher prenatal adversity, high maternal sensitivity would serve as a protective factor. Participants were 247 primarily low-income, diverse dyads. Results indicated a significant interaction effect of maternal sensitivity and prenatal adversity on externalizing problems. The association between prenatal adversity and externalizing behaviors was significant only among children who experienced low prenatal adversity, with higher maternal sensitivity associated with lower externalizing behaviors. These findings indicate that, in the absence of high prenatal risk, responsive and sensitive parenting can buffer children in an otherwise high-risk sample from the development of externalizing behaviors.  相似文献

What aspects of infants’ prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In study 1, 11 month olds (N = 134) were observed to coordinate vocalizations and gestures with gaze to their caregiver's face at above chance rates, indicating that they are plausibly intentionally communicative. Study 2 tested whether those infant communicative acts that were gaze‐coordinated best predicted later expressive vocabulary. We report a novel procedure for predicting vocabulary via multi‐model inference over a comprehensive set of infant behaviours produced at 11 and 12 months (n = 58). This makes it possible to establish the relative predictive value of different behaviours that are hierarchically organized by level of granularity. Gaze‐coordinated vocalizations were the most valuable predictors of expressive vocabulary size up to 24 months. Study 3 established that caregivers were more likely to respond to gaze‐coordinated behaviours. Moreover, the dyadic combination of infant gaze‐coordinated vocalization and caregiver response was by far the best predictor of later vocabulary size. We conclude that practice with prelinguistic intentional communication facilitates the leap to symbol use. Learning is optimized when caregivers respond to intentional vocalizations with appropriate language.  相似文献

Summation tests were used to assess whether participants in a human predictive judgement task learned that some cues (foods) prevented the occurrence of the outcome (migraine). In three experiments the preventative effect of a conditioned inhibitor, I, trained in the design, P+, PI-, I-, was stronger than that of a negative control cue, N, that had been presented alone with the same frequency and simply predicted no outcome. This control cue, N, also passed the summation test when compared to a novel control cue. Experiments 2 and 3 examined whether the latter negative control effect was attributable to differential inhibition. Manipulations designed to alter context learning and the magnitude of the negative contingency did not affect the properties of the negative control cue. Thus, these experiments did not support the possibility that a cue given simple negative training acquires differential inhibition. Regardless of the mechanism underlying the negative control effect, the consistent finding that the conditioned inhibition cue, I, reduced prediction of the outcome more than did the negative control cue, N, provides evidence for true conditioned inhibition whose acquisition requires co-occurrence of the preventative cue with a positive training cue.  相似文献

Relationship distress and divorce are major risk factors for the development or exacerbation of psychopathology and psychosocial impairments. Given that heightened negative emotions within couples’ interactions may portend negative relationship outcomes, it is critical to understand how emotions unfold across a conversation and how partners may influence each other’s immediate emotional experiences. This study examined whether these regulatory dynamics within one interaction predicted relationship satisfaction concurrently and 25 years later. Vocally‐encoded emotional arousal (f0) was measured during couples’ (N = 25 couples) conversations about a relationship issue. Across different analytical strategies, results demonstrate that one partner’s f0 dynamics had immediate and long‐term associations with the other partner’s satisfaction. Partners were less satisfied if the other partner (a) expressed higher f0 overall and (b) escalated more in f0 across the conversation. Yet, partners were more satisfied when their f0 escalated across the conversation. Also, women specifically were more satisfied if their f0 remained elevated longer before regulating back to their emotional baseline. Thus, higher f0 was associated with higher satisfaction in the same partner, but associated with less satisfaction in the other partner—particularly when these emotions come from women. It may be that partners have to decide whether to prioritize expressing their emotions fully or limit expression in the service of their partner’s happiness. These findings challenge us to think of ways to address this “win–lose” scenario so that couples can balance both partners’ emotional needs and preserve relationship quality across the life span.  相似文献

A large body of literature demonstrates the association between body image disturbances and health compromising behaviors among women (e.g., pathological eating, substance use, inappropriate exercise). However, given that disturbed body image is a pervasive problem, it is likely inversely related to health maintenance behaviors. Cancer screenings for breast, skin, and cervical cancer represent an important type of health maintenance behavior, yet adherence rates are low. Given the body-focused nature of these screenings, body image may be a salient predictor. This paper reviews the literature on the relationship between body image disturbances and cancer screening behaviors among women culminating in the proposal of a theoretical model. This model posits that body shame and body avoidance predict performance of cancer screenings and that variables drawn from the cancer literature, including risk perception, health anxiety, subjective norms, and self-efficacy, may moderate this relationship. Clinical implications and suggestions for research are discussed.  相似文献

This study investigated episodic and procedural memory retention in early and late pregnancy and whether memory retention was related to sleep disruption. Twenty‐six women in the third trimester of pregnancy, 20 women in the first trimester of pregnancy, and 24 non‐pregnant controls were administered a battery of verbal and visual episodic memory tasks and two procedural memory tasks before undergoing an overnight sleep study. Memory retention was assessed the following morning. Results indicated that as compared with controls, both pregnant groups had reduced retention in verbal episodic memory but were unimpaired on visual and procedural memory tasks. The pregnant women also demonstrated significant disruption of sleep patterns. Reduced verbal memory retention during pregnancy was not attributable to any measure of sleep; however, small correlations between some indices of sleep and memory do not allow full dismissal of the sleep‐dependent memory consolidation hypothesis.  相似文献

The authors studied the influences of valence information on preschool children's (n = 47) moral (good or bad), liking (liked or disliked by a friend), and consequence-of-behavior (reward or punishment) judgments. The authors presented 8 scenarios describing the behavior valence, positive valence (help, share), negative valence (verbal insult, physical aggression), and disposition valence (nice or mean) of characters in social interaction with a friend. Overall, character disposition and behavior valence significantly influenced children's judgments. Moral, liking, and consequence-of-behavior judgments varied significantly by character disposition for both positive behavior scenarios. In contrast, there were fewer significant findings as a function of character disposition for negative behavior scenarios, suggesting that the negative behavior cue somewhat diminished the effect of character disposition on children's judgments. The authors discuss preschool students’ coordination of information about valence of behavior and character disposition and the students’ reluctance to judge that misbehavior warrants punitive consequence.  相似文献
