The purpose of this study was to investigate the prevalence and characteristics of habit behaviors exhibited by individuals with mental retardation living in the community. Two hundred and fifty-nine direct care staff and parents from the upper mid-west and northeast regions of the country completed a survey measuring the prevalence of major habit disorders (bruxism, trichotillomania, motor/vocal tics, and stuttering) and habit behaviors exhibited by individuals with mental retardation being served by community residential agencies. Habit disorders were also subjectively evaluated according to the respondents' perception of the severity and noticeability of the behavior, and naturalness of appearance of the individual. In addition, respondents indicated their usual reaction to the habit disorder. Overall, stuttering was found to be the most prevalent habit disorder (32%), followed by tics (16·6%), bruxism (13·1%), and trichotillomania (5%) for the sample surveyed. Furthermore, differences were found in the prevalence of habit disorders and other habit behaviors by level of mental retardation and age (adults versus children/adolescents). The implications and limitations of the data, as well as suggestions for future investigations of habit disorders and habit behaviors exhibited by individuals with mental retardation, are discussed. © 1998 John Wiley & Sons, Ltd. 相似文献

The effects of noncontingent matched stimulation (NMS) and response blocking on a boy's stereotypic behavior were evaluated using a multiple schedule that contained three 15-min components (preintervention, intervention, and postintervention). Results showed that stereotypy was always higher after response blocking than before response blocking and was always lower after NMS than before NMS. These results suggest that response blocking may have produced deprivation for the product of stereotypy and that NMS may have provided stimulation that was similar to the product of stereotypy. 相似文献

In a replication and extension of Grice (2004), participants in the current study rated themselves and other known individuals on scales constructed from their own personal constructs and on marker items for the Big Five model personality traits. Confirmatory components analyses revealed excellent fit for the Big Five Model when applied to aggregate trait ratings but highly variable fit when applied to participants' individual ratings. Comparisons of the personal construct and trait ratings indicated an approximate average overlap of only 51%, and additional analyses revealed several factors that contributed to the uniqueness of the personal constructs. These findings were discussed in the context of the idiographic-nomothetic distinction drawn in personality psychology. 相似文献

We suggest that when readers experience narratives, their expectations about the likelihood of narrative events are informed by two types of analyses. Reality-driven analyses incorporate real-world constraints involving, for example, time and space; plot-driven analyses incorporate concerns about outcomes that emerge from the plot. We explored the interaction of these two types of analyses in the application of temporal situation models. Participants read stories in which the final episode occurred after a minute time shift (i.e., "A minute later...") or hour time shift (i.e., "An hour later..."). Our experiments assessed participants' judgments and reading times for statements describing the state of events (e.g., the possibility that characters could carry out particular behaviors) following each type of time shift. Experiments 1A and 1B demonstrated that readers are appropriately sensitive to the real concomitants of time shifts. Experiments 2A and 2B demonstrated, even so, that plot-driven preferences modify judgments and reading times away from reality-driven expectations. Our results have implications for the role of the reader in theories of narrative comprehension. 相似文献

The development of children's rule use on the balance scale task 总被引:6,自引:0,他引:6
Cognitive development can be characterized by a sequence of increasingly complex rules or strategies for solving problems. Our work focuses on the development of children's proportional reasoning, assessed by the balance scale task using Siegler's (1976, 1981) rule assessment methodology. We studied whether children use rules, whether children of different ages use qualitatively different rules, and whether rules are used consistently. Nonverbal balance scale problems were administered to 805 participants between 5 and 19 years of age. Latent class analyses indicate that children use rules, that children of different ages use different rules, and that both consistent and inconsistent use of rules occurs. A model for the development of reasoning about the balance scale task is proposed. The model is a restricted form of the overlapping waves model (Siegler, 1996) and predicts both discontinuous and gradual transitions between rules. 相似文献

The anatomy of the planum temporale (PT) and posterior ascending ramus (PAR) was studied in vivo in 67 healthy right- and left-handed adults using MRI-based morphometry. The left PT was significantly larger than the right, and there was a weakly significant effect of the right PAR larger than the left. A leftward PT asymmetry was found in 72%, and a rightward PAR asymmetry was found in 64% of the sample. The "typical" configuration of a larger left PT and larger right PAR co-occurred in 56% of the subjects studied, which was only slightly more often than predicted by chance. Eight of 67 subjects had "reversed" PT and PAR asymmetries, with consistent left and mixed handers over-represented in this group. Right PAR size was the only variable that predicted writing hand, and left PT size was the only measure that differed by sex. The left PT was expanded relative to the left PAR in 93% of the sample, suggesting that this configuration may be developmentally regulated and may be a critical substrate for the development of language. These findings demonstrate that important relationships exist between hand preference, and the anatomy of posterior cortical language areas. 相似文献

This study compared intrusive (N =15) and withdrawn (N = 10) mothers' ratings of their own interaction styles with their infants and the behaviors of videotaped models of intrusive and withdrawn mothers. Withdrawn mothers rated themselves as less withdrawn than the model withdrawn mother. Intrusive mothers viewed themselves as more intrusive than the model intrusive mother. Both groups viewed their own infants as more outgoing than the infants of the model intrusive and withdrawn mothers. The withdrawn mothers reported feeling more distressed when they observed an infant (of an intrusive or withdrawn mother) crying, suggesting that they feel more empathy than the intrusive mothers. © 2001 Michigan Association for Infant Mental Health. 相似文献

In two experiments, events that were recorded using continuous duration recording (CDR) were rescored using 10‐s partial interval (PIR), 10‐s momentary time sampling (MTS) and 20‐s MTS. Results of Experiment 1 showed that data paths generated by each interval method produced conclusions about functional control that were similar to those based on CDR when using reversal designs; however, for multielement designs, 10‐s PIR was prone to showing differentiation between data paths that was not evident with CDR. Results of Experiment 2 showed that both 10‐s and 20‐s MTS yielded data paths on behavior–behavior relations (e.g., covarying responses) that were consistent with CDR whereas 10‐s PIR produced some behavior–behavior patterns that were not. In both experiments, 10‐s MTS generated data paths that were nearly identical to the respective CDR data paths. The implications of these findings for researchers and clinicians are briefly discussed. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

This study explored three aspects of peer group membership in adolescence: peer group affiliation, the importance of group membership, and a sense of peer group belonging. Each is considered in relationship to adolescents' behavior problems as measured by the Achenbach Youth Self-Report. Participants included an ethnically and socioeconomically diverse sample of 733 adolescents ranging in age from 11 to 18 years. Girls reported more internalizing problems and boys reported more externalizing problems. Girls also reported a higher sense of peer group belonging than boys. When controlling for adolescent age, gender, ethnicity, parent's educational level, and family structure, a sense of peer group belonging was negatively related to internalizing and externalizing behavior problems. Adolescents who viewed peer group membership as very important to them and had a positive sense of peer group belonging had significantly fewer behavior problems than those who viewed peer group membership as very important but did not have a positive sense of peer group belonging. 相似文献

This study explored the role of social comparison processes in fostering contentment among those who are objectively disadvantaged. We focus on how comparisons can produce gender differences in personal entitlement, perceptions of one's own performance, and pay satisfaction. We hypothesized that individuals would base judgments of entitlement, performance, and pay satisfaction more on comparisons with ingroup (same-sex) than outgroup (cross-sex) others, even when both types of comparison information were equally available, unavoidable, and made clear the disadvantaged status of the ingroup. As predicted, the amount students felt they were entitled to be paid, how well they thought they had performed (women only), and how satisfied they were with their pay were all influenced more by same-sex than cross-sex comparison information. The implications of these results for the tolerance of injustice among disadvantaged groups are discussed. 相似文献
