The implementation of behavior modification techniques in school settings often relies on effective training of teachers as mediators. At the conclusion of Phase I, the performance of an experimental group of 13 teachers who were taught behavior modification by means of an inservice workshop was compared with a no-treatment control group. Although the experimental group scored higher on a paper-and-pencil test of behavior modification, there were no differences between the two groups on selected observed in-class behaviors. During Phase II, half of the experimental group of teachers received two hours of bug-in-the-ear (BIE) training in their own classrooms. BIE resulted in changes in the classroom behaviors of praise and contingency statements. These results are discussed in terms of the situation and response mode specificity of behavior and in terms of the implications for future workshops and research. 相似文献

Developmental dyslexia (DD), a severe and frequent disorder of reading acquisition, is characterized by a diversity of cognitive and motor deficits whose interactions still remain under debate. Although deficits in the automatization of sensorimotor control have been highlighted, internal action representation allowing prediction has never before been investigated. In this study, we considered action representation of 18 adolescents with pure DD and 18 age-matched typical readers. Participants actually and mentally performed a visually guided pointing task involving strong spatiotemporal constraints (speed/accuracy trade-off paradigm). While actual and mental movement times of typical readers were isochronous and both conformed to Fitts’ law, the movement times of dyslexics differed between conditions, and only the actual movement times conformed to Fitts’ law. Furthermore, the quality of motor imagery correlated with word reading abilities. This suggests that the process of action representation is impaired in pure DD and supports the sensorimotor perspective of DD. Theoretical implications are discussed. 相似文献
Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study. 相似文献
To better understand how sexualized music videos affect women’s responses to intimate partner violence (IPV), we examined the role of individual variability in perceived victim pain and perceived victim culpability in moderating and mediating (respectively) the priming effects of sexual music videos on women. Female Fijian college students (n?=?243) were randomly assigned to one of three viewing conditions: stereotyped sexual music videos, non-stereotyped/non-sexual music videos, or neutral videos. All participants then read a portrayal of a male-toward-female IPV episode and their perceptions of the female victim and male perpetrator were assessed. Only women who minimized the victim’s pain were adversely affected by exposure to the stereotyped sexual videos. Specifically, for women who perceived low victim pain, those in the stereotyped video condition perceived the victim as more culpable and reported greater perpetrator-directed favorable responding than those in the other two conditions. For these women who perceived low victim pain, perceptions of victim culpability mediated the impact of video type on perpetrator-favorable responding. The findings help us better understand susceptibility to the negative impact of stereotypical sexual videos and highlight areas, such as emphasizing the suffering of victims and reducing myths about victim culpability, which may be worthy of particular emphasis in interventions.
We evaluated whether teaching tacts of images with or without backgrounds would affect acquisition during teaching and generality across untaught targets with four children diagnosed with autism spectrum disorder. Including backgrounds could slow acquisition but bolster generality across other media containing backgrounds, whereas removing backgrounds may improve acquisition but result in poorer generality. Overall, acquisition rates were similar across conditions for three children, although one child displayed consistently slower acquisition during the background condition. We rarely observed generality to untaught targets when programming extinction, but embedding differential reinforcement or teaching additional images with backgrounds led to equally successful outcomes irrespective of initial teaching conditions. Teaching with or without backgrounds may result in marginal differences in acquisition of teaching and untaught targets, especially when arranging supplemental procedures during tests for generality. We discuss the importance of intrasubject replication, considerations when testing for generality, and implications for practice. 相似文献
