Two studies investigated overweight in African American girls. First, African American adolescent girls (BMI was ≥ 85th percentile) and their mothers participated in focus groups addressing weight and eating. Although mothers and daughters shared some similar views on these issues, there were important discrepancies, with mothers expressing greater doubt about the potential success of a healthy weight program. The second study evaluated baseline data from 39 African American girls participating in a weight management program; mothers' reports were also analyzed. In both studies, adolescents reported significant teasing, and in the second study, teasing was inversely associated with social quality of life (β=.55, t=3.01, p=.007). Motivation to participate was positively associated with teasing (r=.50, p < .01). Self-esteem was inversely related to positive health habits (all p < .05). Mothers who viewed their daughters as having higher self-esteem were less concerned about their daughters' weight. Differences in mothers' and daughters' perceptions highlight the importance of a family approach in pediatric overweight interventions. Results provide evidence that overweight African American girls face significant weight stigmatization and suggest areas to target regarding intervention implementation.

This study used a computer-based emotional word-recognition task to assess the emotional processing styles of repressive–defensive youth. A hypothesis was tested proposing that adolescent repressive–defensive coping style is associated with rapid engagement and disengagement of emotional stimuli (negative and positive). Data were collected on a male adolescent sample enrolled in a juvenile diversion program allowing for the comparison of anxious, low-anxious, and repressive–defensive youth. Consistent with prediction, repressive–defensive participants exhibited facilitated responding to emotional relative to neutral word stimuli across valence category (i.e., positive and negative). In contrast, anxious participants exhibited a unique pattern of facilitated responding to positive word stimuli. The current findings represent a first attempt at investigating the processing impairments of repressive–defensive coping style in a nonadult sample. Results are interpreted in light of broader adult and child research findings on emotional processing and affective disturbance.  相似文献

Pleasantness and intensity ratings of beverages served in containers congruent and incongruent with expectancy were assessed. Past research has shown that the violation of food expectancies, e.g., color, taste, temperature, leads to more negative evaluations of food. Thus, it was hypothesized that beverages sampled from a container incongruent with expectancy, e.g., beer from a coffee cup, would be rated less favorably than the same beverage sampled from a container congruent with expectancy, e.g., beer from a beer bottle. 61 participants evaluated three beverages (beer, orange juice, and hot chocolate) in three containers (bottle, glass, and cup) using 11-point rating scales for pleasantness and intensity. Analysis indicated beverages were rated as significantly more pleasant in containers congruent with expectancy, as well as rated more intense when presented in bottles. These results further address the effects of violating expectations on producing negative hedonic evaluations.  相似文献

Recent developments in the analysis of derived relational responding, under the rubric of relational frame theory, have brought several complex language and cognitive phenomena within the empirical reach of the experimental analysis of behavior. The current paper provides an outline of relational frame theory as a new approach to the analysis of language, cognition, and complex behavior more generally. Relational frame theory, it is argued, also provides a suitable paradigm for the analysis of a wide variety of social behavior that is mediated by language. Recent empirical evidence and theoretical interpretations are provided in support of the relational frame approach to social behavior.  相似文献

We investigated individual differences in the stimulus control of navigational behavior in the water maze by comparing measures of place learning in one environment to measures of latent learning (via passive placement on the goal platform) in a novel environment. In the first experiment, 12 rats were trained to find a slightly submerged hidden platform at a fixed location in room A for 10 days (4 trials/day). Fast and slow place learners were identified by their mean escape latency and cumulative distance to the goal during acquisition. The same animals were then given a 2-min passive placement on the submerged platform in room B. Latent learning was assessed by the animal's escape latency on a single swim trial immediately following the placement in room B. The results showed that the good latent learners in room B were not necessarily the fast place learners in room A. This weak correlation may be related to the fact that some rats swam near the area in room B that corresponded to the former goal location in room A relative to a common polarizing cue (i.e., the door/entrance to both rooms). When the view of the door was blocked in a second experiment a significant positive correlation between place acquisition and the latent learning test was obtained, although escape performance following passive placement was not improved. These findings suggest that while place navigation and latent learning via passive placement may involve some common cognitive-spatial function, other associative (S-S and/or S-R) processes that occur during place navigation/active movement may be required for animals to exhibit truly accurate navigational behavior characteristic of asymptotic escape performance in the water maze. Additional implications for neurobiological studies using a procedural pretraining design are discussed.  相似文献

The objective of the present study was to investigate the comparative criterion‐related validity of different statistical operationalizations of group general cognitive ability (i.e., mean, maximum, and minimum) as a function of task type based on Steiner's (1966, 1972) task typology. In contrast to recent investigations, we hypothesized that, regardless of task type, the mean of group members’ general cognitive ability would predict group performance as well as or better than other statistical operationalizations of group general cognitive ability. We conducted a laboratory study where 157 four‐person groups worked on 4 tasks that conformed to Steiner's typology (additive, compensatory, conjunctive, and disjunctive). The results indicate that the mean was the strongest predictor of group performance across all 4 task types and, in particular, was significantly stronger than the maximum and minimum on both the disjunctive and conjunctive tasks.  相似文献

Because of high levels of risk behavior, adjudicated adolescents are at high risk for negative health outcomes such as nicotine and drug addiction and sexually transmitted diseases. The goal of this article is to examine relationships between future orientation and impulsive-sensation-seeking personality constructs to risk behaviors among 300 adjudicated adolescents. Significant relationships between impulsive sensation seeking and future orientation were found for several risk behaviors. Individuals with more positive future orientation were less likely to use marijuana, hard drugs, alcohol during sex, had fewer alcohol problems, had lower levels of alcohol frequency and quantity of use, and perceived greater risks associated with such behaviors. Higher impulsivity reliably predicted alcohol problems, alcohol use, condom use, and cigarette smoking.  相似文献

The present theory-driven, empirical evaluation examined cross-sectional influences on men’s engagement in risky body change behaviors. The study tested a slightly revised version of the Tripartite Influence Model (Thompson et al. 1999) with a sample of 156 male undergraduate students from the Midwestern Region of the United States. Participants completed measures pertaining to body image and health-risk behaviors. Consistent with the Tripartite Influence Model (Thompson et al. 1999), individual psychological variables mediated the association between sociocultural influences and muscularity-oriented body dissatisfaction. Body dissatisfaction mediated the relation between psychological variables and engagement in body change behaviors. Theoretical models developed to explain body change behaviors among women may be applicable to men when constructs are assessed in ways that are relevant to men.  相似文献
