The function of perseverative speech for an adult man who had been diagnosed with autism and mental retardation was examined. Results showed that verbal perseverations were maintained by social attention. An intervention consisting of differential reinforcement of appropriate verbal responses and extinction of perseverative verbal responding was effective in decreasing verbal perseverations.  相似文献

We evaluated the efficacy of a brief staff-training procedure to increase the use of graduated prompting by 2 certified nursing assistants (CNAs) while they helped to dress 3 persons with dementia in a seven-bed dementia care unit. The multiple baseline design across participants showed that CNAs dressed residents with minimal resident involvement during baseline observations. Following brief in-service training, CNAs provided graduated prompts and praise appropriately, suggesting that CNAs can promote active involvement in personal care routines by older adults with dementia.  相似文献

Media commentators have suggested that recent school shootings were precipitated by social rejection, but no empirical research has examined this claim. Case studies were conducted of 15 school shootings between 1995 and 2001 to examine the possible role of social rejection in school violence. Acute or chronic rejection—in the form of ostracism, bullying, and/or romantic rejection—was present in all but two of the incidents. In addition, the shooters tended to be characterized by one or more of three other risk factors—an interest in firearms or bombs, a fascination with death or Satanism, or psychological problems involving depression, impulse control, or sadistic tendencies. Implications for understanding and preventing school violence are discussed. Aggr. Behav. 29:202–214, 2003. © 2003 Wiley‐Liss, Inc.  相似文献

The present study investigated the influence of mood on self-set goals and task performance. Results from 2 studies suggest a restricted view of mood effects in which affective state influences the level of self-set goals or task performance, but not both. Study 2 reveals asymmetrical mood effects on task performance, with positive- and negative-mood participants exceeding the baseline performance of neutral mood participants. Evidence indicates that goal-setting instructions may alter how individuals interpret motivational implications of mood. Although theory implies an inclusive view in which mood has both direct and indirect (through goal-setting) performance effects, the conflicting influences of affect infusion at different points of the goal-striving process may diminish the likelihood of observing inclusive effects.  相似文献

This study explored relationships between perceptions of intra-team communication and role ambiguity within an interdependent team sport environment. Participants were 116 intercollegiate-level team sport athletes ( M age = 20.6 years). For males, the intra-team communication dimension of acceptance was found to predict the majority of role ambiguity dimensions for both performance contexts of offense and defense (.09 ≤  R ²_adj. ≤ .16). However, limited support for this relationship was found for females, as acceptance communication predicted only one role ambiguity dimension (evaluation of role performance on defense). These findings have implications for applied practice in terms of reducing group members' perceptions of role ambiguity in interdependent team sport.  相似文献

Establishing operations (EO) influence operant responding by altering the reinforcing effectiveness of consequences (reinforcer establishing or abolishing effect) and changing the frequency of behavior that has been reinforced by those consequences in the past (evocative or abative effect) (Michael, 1982 , 1993 ). In this study we attempted to isolate the evocative and abative effects of an EO for positively reinforced challenging behavior with a person with autism and developmental disabilities. The study consisted of three phases. First, an analogue functional analysis identified attention as maintaining challenging behavior. Second, access to attention was systematically controlled (continuous access versus no access) immediately prior to functional analysis sessions in which the participant received attention on an FR1 schedule. Results of this phase indicated that challenging behavior occurred at higher levels during the functional analysis sessions when access to attention was restricted immediately prior to sessions (i.e., no access appeared to function as an EO). In the third phase, prior access to attention was again controlled as in the second phase of the study, however the participant was then placed on extinction. The results of this final phase seem to indicate that no access to the reinforcer prior to extinction had an evocative effect (produced high levels of responding) whereas access to the reinforcer had an abative effect (produced lower levels of responding) during extinction sessions.

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines.  相似文献

This paper delineates a bridging strategy for generalizing a theoretical proposition about human judgment from laboratory to field settings. This strategy encompasses experimental and archival methods, emphasizing each method’s complementary rather than competitive advantage. Basic experiments that use generic tasks and settings, and novice subjects, contribute empirical tests that maximize internal validity. Given a target area in the “real world” for generalizing the proposition, applied experiments that use tasks and settings with greater mundane realism, and professional subjects from the target area, contribute replicating tests that balance internal and external validity. As a complement to experimentation, archival research adds value by testing observable implications of the proposition in field settings. We relate the bridging strategy to judgment research on the dilution effect (i.e., the presence of nondiagnostic cues, when processed with diagnostic cues, causes judges to under-weigh the diagnostic cues) in psychology and applied areas. Finally, we contribute an archival data analysis that uncovers indirect evidence, or a cognitive footprint, of the dilution effect in a professional judgment setting where social and economic mechanisms potentially discipline systematic error.  相似文献

Child-rearing attitudes among East Asian groups have been emphasized in the developmental psychology literature in the context of their association with academic achievement. Although child-rearing attitudes play an important role in the transmission of cultural values, much of the research on East Asian child-rearing attitudes has ignored cultural variables and has instead focused on authoritarian parenting style. The current study examined the association between three classes of variables-culture (i.e., ethnic identity, self-construal, acculturation), demographics (sex, years in the US, English fluency), and self-disclosure-and traditional child-rearing attitudes (TCRA) among East Asian immigrants in the United States. It was hypothesized that higher levels of TCRA would be associated with higher levels of ethnic identity, interdependent self-construal, separation, and guarded self-disclosure, and fewer years spent in the United States. The participants included 170 East Asian (Chinese, Japanese, and Korean) immigrants (88 men, 82 women) who were administered a battery of psychometrically established measures. Our hypotheses were largely supported. We found that, while there was no significant sex by ethnicity effect for TCRA, men were significantly more likely than women to endorse TCRA and the Korean group had significantly higher TCRA than the Japanese group. Ethnic identity, interdependent self-construal, separation, years in the US, and guarded self-disclosure were significant independent predictors of TCRA. The findings suggest the need for broadening the content of assessment tools of child-rearing attitudes and measuring associated cultural and noncultural variables among East Asian ethnic groups. Future research on child-rearing attitudes among Asian ethnic groups may benefit from (1) measuring multiple dimensions of TCRA, (2) assessing associated cultural variables directly rather than inferring them in an ad hoc fashion based on observed ethnicity differences, (3) measurement of demography (including sex and years spent in the host country) and (4) examining the potential influence of guarded self-disclosure.  相似文献

Participants were pretrained and tested on mutually entailed trigonometric relations and combinatorially entailed relations as they pertained to positive and negative forms of sine, cosine, secant, and cosecant. Experiment 1 focused on training and testing transformations of these mathematical functions in terms of amplitude and frequency followed by tests of novel relations. Experiment 2 addressed training in accordance with frames of coordination (same as) and frames of opposition (reciprocal of) followed by more tests of novel relations. All assessments of derived and novel formula‐to‐graph relations, including reciprocal functions with diversified amplitude and frequency transformations, indicated that all 4 participants demonstrated substantial improvement in their ability to identify increasingly complex trigonometric formula‐to‐graph relations pertaining to same as and reciprocal of to establish mathematically complex repertoires.  相似文献
