Body image and eating disorders in older adults: a review 总被引:2,自引:0,他引:2
Researchers have shown body image to be an important part of a person's self-concept and have linked body dissatisfaction to various psychopathologies, most frequently eating disorders. However, the majority of the literature to date has focused on adolescents and college-aged samples, with little attention paid to the course of body image and eating disorders throughout the life span. The present article reviews the available literature on body image and eating disorders in older adults to understand more fully the unique presentation of body concerns and disordered eating across the life span. The authors address unique factors affecting body dissatisfaction and the development of eating disorders among older adults and offer directions for future research. 相似文献

The authors investigated the impact of response activation on dual-task performance by presenting a subliminal prime before the stimulus in Task 2 (S2) of a psychological refractory period (PRP) task. Congruence between prime and S2 modulated the reaction times in Task 2 at short stimulus onset asynchrony despite a PRP effect. This Task 2 congruence effect was paralleled by a Task 1 congruence effect and emerged exclusively under conditions of cross talk, whereas it did not occur under dual-task conditions preventing cross talk between tasks. This suggests that response activation operates during the PRP in dual tasks and affects the response times in Task 2 via cross talk between common processing elements at prebottleneck stages but not by directly affecting the postbottleneck stages. 相似文献

Interaction between the cerebral hemispheres may allow both hemispheres to contribute their processing resources in order to cope efficiently with complex tasks [Banich, M. (1998). The missing link: the role of interhemispheric interaction in attentional processing. Brain and Cognition, 36, 128-157]. The current study investigated whether the benefits of interhemispheric interaction arise because of top-down knowledge about the task built up over the course of a block of trials or because of the processing demands present in a single trial. Participants performed a less computationally complex physical identity task and a more complex adding task on within-visual field and across-visual field trials. Task differences in interhemispheric interaction were compared between the blocked and mixed conditions to investigate whether frequent task switches altered the pattern of interhemispheric resource recruitment. A similar interaction between task difficulty and trial type (across- or within-visual field presentation) was obtained for both the blocked and mixed conditions. The degree of task-dependency of interhemispheric interaction was not altered in the mixed condition. This finding supports the view that interhemispheric interaction becomes beneficial in response to the processing demands of an individual trial rather than as a result of top-down task knowledge. 相似文献

The authors investigated whether speakers who named several objects processed them sequentially or in parallel. Speakers named object triplets, arranged in a triangle, in the order left, right, and bottom object. The left object was easy or difficult to identify and name. During the saccade from the left to the right object, the right object shown at trial onset (the interloper) was replaced by a new object (the target), which the speakers named. Interloper and target were identical or unrelated objects, or they were conceptually unrelated objects with the same name (e.g., bat [animal] and [baseball] bat). The mean duration of the gazes to the target was shorter when interloper and target were identical or had the same name than when they were unrelated. The facilitatory effects of identical and homophonous interlopers were significantly larger when the left object was easy to process than when it was difficult to process. This interaction demonstrates that the speakers processed the left and right objects in parallel. 相似文献

Although the presence or absence of a pitch accent clearly can play an important role in signaling the discourse and information structure of an utterance, whether the form of an accent determines the type of information it conveys is more controversial. We used an eye-tracking paradigm to investigate whether H*, which has been argued to signal new information, evokes different eye fixations than L+H*, which has been argued to signal the presence of contrast. Our results demonstrate that although listeners interpret these accents differently, their interpretive domains overlap. L+H* creates a strong bias toward contrast referents whereas H* is compatible with both new and contrast referents. 相似文献

This study examined the association of Axis I and Axis II disorders among offenders who were in prison-based substance abuse treatment in a national multi-site study. Participants (N = 280) received a psychosocial assessment and a structured diagnostic interview in two separate sessions. Logistic regression models examined the association between lifetime mood and anxiety disorders with two personality disorders, and the relationship of Axis I and Axis II disorders (alone and in combination) to pre-treatment psychosocial functioning. Over two-thirds of the sample met criteria for at least one mental disorder. Borderline personality disorder was strongly associated with having a lifetime mood disorder (odds ratio = 7.5) or lifetime anxiety disorder (odds ratio = 8.7). Individuals with only an Axis II disorder, or who had both Axis I and Axis II disorders, had more severe problems in psychosocial functioning than those without any disorder. Clinical treatment approaches need to address this heterogeneity in diagnostic profiles, symptom severity, and psychosocial functioning. 相似文献

This study represents the first step toward systematic behavioral treatment development and pilot testing of a novel approach to smoking cessation that utilizes adults interested in helping someone to stop smoking (i.e., support persons) as the agent of change. The counselor manual for a telephone-based intervention for support persons was developed based on a previous clinic-based intervention. Social cognitive theory served as the conceptual basis for the intervention. Ten adult non-smoking females completed the treatment protocol, consisting of six 20 - 30-min sessions and written materials. The support person was the sole recipient of the professional intervention. Feedback was obtained from 8 of the 10 participants and all 4 telephone counselors 1 week post-treatment (week 10). Results indicate that the telephone-based intervention was feasible and acceptable to participants. The intervention was refined based on participant and counselor feedback and will be subsequently tested in a randomized pilot trial. 相似文献

This study compared a sample of 273 juvenile (aged 14 to under 18), 178 adolescent (aged 18 to under 21) and 273 adult (older than 20 years) male sex offenders modus operandi (or MO, the way in which they committed their offenses), frequency of recidivism and predicted recidivism via the static-99. In terms of the frequencies of the MO aspects we found that juveniles and adolescents differed significantly from adult sexual offenders. However, concerning the frequency of sexual violent behaviors, adolescents committed more severe offenses in contrast to the two other groups. The comparison of recidivism rates indicated that adolescent sexual offenders were significantly less likely to commit a new sexual offense, but were considerably more likely to commit a non-sexual violent offense compared to adult sexual offenders. For juvenile offenders, only few static-99 variables were predictive of future recidivism in comparison to the other groups, suggesting that the static-99 may only have a restricted utility in juvenile offenders. Further, juvenile offenders risk levels were found to fall primarily within the medium risk group making individual differentiation of potential risk difficult. It is suggested that additional predictors, which help to differentiate young sexual offenders must be investigated. 相似文献

The purpose of the current study was to examine blending and segmenting of phonemes as an instance of small, textual response classes that students learn to combine to produce whole word reading. Using an A/B/A/B design, a phoneme segmenting and blending condition that included differential reinforcement for response classes at the level of phonemes was compared to a control condition which was equated for differential reinforcement of reading words and opportunities to respond. The critical difference between conditions was the size of the responses that were brought under stimulus control (phonemes versus whole words). Findings clearly supported the superiority of the phoneme blending treatment condition over the control condition in producing generalized increases in word reading. The results are discussed in terms of the behavioral mechanisms that govern early literacy behaviors and the essential role that targeting measured increases in academic responses plays in furthering our understanding of how to improve the analysis and instruction of students who need to learn these important skills. 相似文献
