Many functional assessment procedures have been developed and validated for use with people with intellectual and developmental disabilities. However, there is a paucity of research exploring the utility and social acceptability of functional assessment methods for people with dementia. We conducted direct observations in the natural environment to produce data for conditional probability analyses and an experimental functional analysis of the behavior of two women with dementia. We found that the conditional probability analysis yielded similar conclusions about function as the data from the experimental functional analysis for both participants. Importantly, staff rated the direct observations as more socially acceptable. We also report barriers to conducting both methods in older adult settings that warrant further exploration, including the use of the assessments with people with dementia and intact vocal verbal repertoires. 相似文献

Many animals have been tested for conceptual discriminations using two-dimensional images as stimuli, and many of these species appear to transfer knowledge from 2D images to analogous real life objects. We tested an American black bear for picture-object recognition using a two alternative forced choice task. She was presented with four unique sets of objects and corresponding pictures. The bear showed generalization from both objects to pictures and pictures to objects; however, her transfer was superior when transferring from real objects to pictures, suggesting that bears can recognize visual features from real objects within photographic images during discriminations. 相似文献

The ability to counteract destabilizing external forces while simultaneously executing a complex task presents a novel way to ascertain one's ability to generate adaptive postural control responses to avoid a potential fall. In this study, participants performed an upper limb object transport task requiring a lateral change in support on a robotic platform that could remain fixed in space or translated (mimicking a slip or trip perturbation). No significant stability differences were observed at initial recovery step between slip and trip perturbations. Variability measures were greatest during the trip perturbations; though stability was at its greatest level preceding these perturbations. These results will aid in the design of future studies that will investigate adaptive postural control responses generated by older adults when executing similar, ongoing complex upper body tasks interrupted by a destabilizing support surface perturbation. 相似文献

Peer victimization is predictive of serious problems in adjustment, especially among children who are both victimized and aggressive. This study investigated how different types of aggression contribute to later victimization. Specifically, we examined prospective relationships between the types of aggression that children perpetrated and the types that they experienced at the hands of others. Trained observers coded schoolyard behavior of 553 children in grades 3–6 during the initial year of a bullying intervention program. Both observed aggression and victimization were specified by form (direct, indirect) and function (proactive, reactive). Total hourly rates of victimization were highest in the upper grades. Direct-reactive aggression uniquely predicted increases in victimization, while direct-proactive aggression predicted decreases, particularly in direct-proactive victimization. Indirect-proactive aggression (e.g., derogatory gossip) predicted increases in indirect-proactive victimization only in the control group. Indirect-reactive aggression and victimization occurred too rarely to detect change. Aggression-victimization relationships did not differ for boys and girls. Discussion considers why children might risk direct reactive aggression in the face of increased victimization. Different sequelae for different forms and functions of aggression highlight the need to resolve theoretical ambiguities in defining proactive and reactive aggression. 相似文献

In a subsample of a multisite stalking study (Mohandie, Meloy, McGowan, & Williams, 2006) comprising 78 offenders from one site, 77% committed new offenses within an average follow-up of 106 months (8.8 years). Over half (56%) were charged for new stalking related offenses and 33% for violent recidivism. Violent reoffending, including sexual offenses, was predicted by risk factors consistent with existing literature: younger age at first conviction, prior release failures, and criminal history. Stalking recidivism was predicted by pre-index offending scores, using the Cormier-Lang, and prior diagnosis of a mental illness. In addition, stalkers with previously diagnosed mental illness had significantly more police contacts as complainants than those without; their recidivism was also more likely to be non-violent. 相似文献
