Dementia is a serious disease affecting a growing number of people. With the onset of dementia comes a decline in social activity engagement that can negatively impact multiple aspects of a person's life. Research suggests that time of day may influence a person with dementia's behavior, including activity engagement, but such research is limited. The purpose of this study was to evaluate the influence of time of day on engagement in activities in persons diagnosed with dementia. An alternating treatments design was used with three participants to measure activity engagement during two times of day, morning and afternoon, and during two activities, a moderately preferred and a low preferred. Results showed no differentiation in engagement between morning and afternoon activities for all three participants, with high levels of engagement during both times of day. For two participants, results showed no differentiation in engagement between moderately preferred and low preferred activities. For one participant, levels of engagement were higher during moderately preferred activities than during low preferred activities.  相似文献

Symptoms of attention-deficit/hyperactivity disorder (ADHD) in elementary school-age children are associated with poor relationships with classroom peers, as indicated by poor social preference, low peer support, and peer victimization. Less is known about how friendship patterns relate to ADHD symptoms, or how friendships may buffer risk for negative peer experiences. Participants were 558 children in 34 classrooms (grades K-5). At the beginning (fall) and end (spring) of an academic year, children completed (a) sociometric interviews to index friendship patterns and social preference, and (b) self-report questionnaires about their support and victimization experiences from classmates. In fall, higher teacher-reported ADHD symptoms were associated with children having more classmates with no friendship ties (non-friends) and who the child nominated but did not receive a nomination in return (unreciprocated friends), and with having fewer classmates with mutual friendship ties (reciprocated friends) and who nominated the child but the child did not nominate in return (unchosen friends). Higher fall ADHD symptoms predicted more non-friend classmates, poorer social preference, and more victimization in the spring, after accounting for the same variables in fall. However, having many reciprocated friends (and to a lesser extent, many unchosen friends) in fall buffered against the trajectory between fall ADHD symptoms and poor peer functioning in spring. By contrast, having many unreciprocated friends in fall exacerbated the trajectory between fall ADHD symptoms and poor peer functioning in spring. Thus, elevated ADHD symptoms are associated with poorer friendship patterns, but reciprocated friendship may protect against negative classroom peer experiences over time.

Abstract

One purpose of the present research was to determine the relationship between perfectionism and eating attitudes among national level rowers. A second purpose was to determine if body mass, weight classification and gender moderate perfectionism-eating attitude relations. Rowers from New Zealand and Australia (W=449) completed the Positive and Negative Perfectionism Scale (PANPS; Terry-Short, Owens, Slade and Dewey, 1995), the Eating Attitude Test-40 (EAT-40; Garner and Garfinkel, 1979), and the Short Form of the Marlowe-Crowne Social Desirability Scale (MC-SDS; Reynolds, 1982). In addition, a Body Mass Index (BMI) was calculated from the height and weight measurements of each participant. Hierarchical multiple regression analyses showed that, after accounting for social desirability effects. Negative (unhealthy) Perfectionism scores were positively related to disturbed eating attitude scores, whereas Positive (healthy) Perfectionism scores were unrelated to disturbed eating attitude scores. In addition, body mass, weight classification and gender operated in a conjunctive fashion to produce a maximum moderator effect. That is, relations between Negative Perfectionism and disturbed eating attitudes were strongest for female lightweight rowers with higher BMI scores. Recommendations for future research are discussed.  相似文献

Information held in working memory (WM) can guide attention during visual search. The authors of recent studies have interpreted the effect of holding verbal labels in WM as guidance of visual attention by semantic information. In a series of experiments, we tested how attention is influenced by visual features versus category-level information about complex objects held in WM. Participants either memorized an object’s image or its category. While holding this information in memory, they searched for a target in a four-object search display. On exact-match trials, the memorized item reappeared as a distractor in the search display. On category-match trials, another exemplar of the memorized item appeared as a distractor. On neutral trials, none of the distractors were related to the memorized object. We found attentional guidance in visual search on both exact-match and category-match trials in Experiment 1, in which the exemplars were visually similar. When we controlled for visual similarity among the exemplars by using four possible exemplars (Exp. 2) or by using two exemplars rated as being visually dissimilar (Exp. 3), we found attentional guidance only on exact-match trials when participants memorized the object’s image. The same pattern of results held when the target was invariant (Exps. 23) and when the target was defined semantically and varied in visual features (Exp. 4). The findings of these experiments suggest that attentional guidance by WM requires active visual information.  相似文献

Behavioral health treatment agencies often struggle to keep clients engaged in treatment. Women clients often have additional factors such as family responsibilities, financial difficulties, or abuse histories that provide extra challenges to remaining in care. As part of a national initiative, four women-focused drug treatment agencies used process improvement to address treatment engagement. Interviews and focus groups with staff assessed the nature and extent of interventions. Women-focused drug treatment agencies selected relational-based interventions to engage clients in treatment and improved four-week treatment retention from 66% to 76%. Process improvement interventions in women-focused treatment may be useful to improve engagement.  相似文献

This study examines the type of relationship that exists between the sales manager and subordinate (vertical exchange status), and its impact on the sales manager's attributions about the subordinate performance, as well as subsequent responses to the subordinate. Results indicate that cadres may receive preferential consideration in explaining their performance, which then impacts the sales manager's response to the salesperson. The findings imply that sales managers should be careful in assigning attributions for performance by both cadre and hired hand salespersons.  相似文献
