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.

The experiments presented here demonstrate that normal aging amplifies differences in time production occurring in delayed free-recall testing. Experiment 1 compared the time production ability of two healthy aged groups as well as college-aged participants. During the test session, which followed a 24-h delay and omitted all feedback and examples of the two target intervals, the two groups of aged participants' over-produced a 6s interval. This effect is similar in form to errors shown by young participants, but twice the magnitude. Productions of a 17 s interval were generally accurate overall. However, further analysis indicated that the majority of aged participants over-produced the 17 s interval while a minority greatly under-produced the 17 s interval. Furthermore, aged participants showed violations of the scalar property of timing variability in the training session, while in the test session, only those who under-produced the 17 s interval showed this tendency. In contrast, training session performance was good for all participants. Experiments 2 and 3 investigated the ability of the participants in Experiment 1 to reproduce the length of a line from memory, under conditions analogous to those of the time production experiments. These experiments provided tests of the specificity of the errors observed in Experiment 1. Performance in the older participants was accurate, if more variable, compared to the young participants, in contrast to the time production results, indicating that production inaccuracy in free-recall is specific to interval timing in the current context.  相似文献

Spatial task performance,sex differences,and motion sickness susceptibility   总被引:1,自引:0,他引:1  
There are substantial individual differences in susceptibility to motion sickness, yet little is known about what mediates these differences. Spatial ability and sex have been suggested as possible factors in this relationship. 89 participants (57 women) were administered a Motion Sickness Questionnaire that assesses motion sickness susceptibility, a Water-level Task that gauges sensitivity to gravitational upright, and a Mental Rotation Task that tests an individual's awareness of how objects typically move in space. Significant sex differences were observed in performance of both the Water-level Task (p<.01), and the Mental Rotation Task (p<.005), with women performing less accurately than men. Women also had significantly higher scores on the Motion Sickness Questionnaire (p<.005). Among men, but not women, significant negative relationships were observed between Water-level Task performance and Motion Sickness Questionnaire score (p<.001) and between Mental Rotation Task performance and Motion Sickness Questionnaire score (p<.005). In conclusion, women performed significantly more poorly than men did on the spatial ability tasks and reported significantly more bouts of motion sickness. In addition, men showed a significant negative relationship between spatial ability and motion sickness susceptibility.  相似文献

Unconscious memory bias in depression: perceptual and conceptual processes   总被引:7,自引:0,他引:7  
Mood-congruent memory (MCM) bias in depression was investigated using 4 different implicit memory tests. Two of the implicit tests were perceptually driven, and 2 were conceptually driven. Depressed participants and nondepressed controls were assigned to 1 of 4 implicit memory tests after studying positive and negative adjectives. Results showed no MCM bias in the perceptually driven tests. MCM was demonstrated in 1 of the conceptually driven tests, but only for adjectives that were conceptually encoded. Results support the theory that mood-congruent processes in depression are limited to conceptual processing. However, activation of conceptual processes may not be sufficient for demonstrating mood congruency.  相似文献

We report a single-case study of peripherally acquired dyslexia that meets the clinical criteria of "alexia without agraphia." The patient, AA, has a large infarct involving the left posterior cerebral artery. The most striking feature is a severe impairment in recognizing single visually presented letters that precludes explicit or implicit access to reading, even in a letter-by-letter fashion. AA can, however, differentiate letters from similar nonsense characters and digits, and he is also able to identify alphanumeric signs when the visual channel is bypassed (through somesthesic or kinesthesic presentation). Spelling tasks are also well performed. Since there is a breakdown in mapping a visually presented letter to its abstract graphemic representation, we propose the term "visuographemic alexia" for this kind of reading disorder. The pattern of deficits is interpreted following theoretical models previously developed in cognitive neuropsychology. An alexia for arabic numerals with preserved comprehension lends additional support for the crucial processing of different notational systems (e.g., phonographic vs logographic). More general perceptive disorders do not seem to account for these patterns; they are material-specific. Finally, we attempt to specify functional correlations with the implied neural networks.  相似文献

This paper is focused on F. W. J. Schelling's view of freedom during the period of the Freiheitsschrift (1809) and related works. It is argued that the standard way this has been understood may be too simplistic. On this standard interpretation of his view, evil is made a matter of free choice by the agent, but where the choice does not concern individual actions, but the choice of the agent's essence in an atemporal act. As a result of this choice, it is argued, Schelling can then make evil imputable. By contrast, I argue that for Schelling freedom does not involve choice, but necessity, but in a way that is still internal to the agent and hence non-coercive, and thus in a way that remains free and makes evil imputable. How Schelling comes to have this view is considered, and some responses are given to ways it might be challenged both interpretatively and philosophically.  相似文献

Three visual habituation studies using abstract animations tested the claim that infants' attachment behavior in the Strange Situation procedure corresponds to their expectations about caregiver-infant interactions. Three unique patterns of expectations were revealed. Securely attached infants expected infants to seek comfort from caregivers and expected caregivers to provide comfort. Insecure-resistant infants not only expected infants to seek comfort from caregivers but also expected caregivers to withhold comfort. Insecure-avoidant infants expected infants to avoid seeking comfort from caregivers and expected caregivers to withhold comfort. These data support Bowlby's (1958) original claims-that infants form internal working models of attachment that are expressed in infants' own behavior.  相似文献

Smith-Magenis syndrome (SMS) is a complex disorder characterized by numerous challenges, including intellectual disability, speech delay, decreased pain sensitivity, sleep disturbances, hyperactivity, mood instability, and self-injury. Caregivers must readily adapt to the ever-changing needs of the child. Due to these demands, caregivers may encounter difficulties maintaining their own level of well-being. Thus, a total of 112 primary caregivers (i.e., parents) of individuals diagnosed with SMS responded to online questionnaires to assess demographic and psychosocial factors, such as perceptions of child health vulnerability, benefit finding, sleep behaviors, anxiety and depression symptomatology, and caregiver satisfaction and self-efficacy, which may be related to caregiver well-being. Results show that, among mothers, caregiver well-being was directly related to perceived child health vulnerability, caregiver satisfaction, and benefit finding, and a significant moderating effect was observed for depression/anxiety counseling after beginning the caregiver role on the relationship between anxiety symptomatology and caregiver well-being. Results further suggest that maternal caregivers who report high levels of anxiety but do not seek counseling fair the worst in terms of well-being. Among fathers, lower depression symptoms and greater benefit finding were related to higher levels of caregiver well-being. These data show that many factors play roles in influencing coping and well-being among SMS caregivers. Investigating these variables and relationships may reveal additional resources and interventions to assist primary caregivers.  相似文献
