This article presents a comprehensive conceptual framework and methodology for characterizing multidimensional psychosocial and behavioral interventions for family caregivers of people with Alzheimer's disease. The methodology involved conducting a detailed task analysis of the interventions, and the application of the analytical hierarchy process. The authors were able to achieve high levels of consistency and reliability using this methodology to decompose and describe the interventions according to a complex conceptual framework comprising 3 dimensions: target domain, functional domain, and delivery system characteristics. Application of this methodology will enhance the ability to describe and measure interventions consistently, make comparisons across studies, isolate causal factors that achieve desired outcomes, and more generally elevate the science of psychosocial intervention research.  相似文献

Pigeons classified a display of illuminated pixels on a touchscreen as sparse or dense. Correct responses were reinforced with six food pellets; incorrect responses were unreinforced. On some trials an uncertain response option was available. Pecking it was always reinforced with an intermediate number of pellets. Like monkeys and people in related experiments, the birds chose the uncertain response most often when the stimulus presented was difficult to classify correctly, but in other respects their behavior was not functionally similar to human behavior based on conscious uncertainty or to the behavior of monkeys in comparable experiments. Our data were well described by a signal detection model that assumed that the birds were maximizing perceived reward in a consistent way across all the experimental conditions.  相似文献

The neurocognitive effects of alcohol have been frequently examined. Studies reveal a wide array of cognitive deficits. Attempts to develop a parsimonious model for these effects have been difficult because of the intra- and intersubject variability. Complicating the development of a model of cognitive deficits in substance abusers is the common practice of polysubstance abuse. The use of theoretical models that focus on the underlying cognitive processes offers flexibility while maintaining sufficient theoretical precision. This article briefly reviews the literature on neurocognitive changes associated with substance abuse as well as the various theoretical models that have been studied. It also provides an overview of recovery of function. Its primary objective is to evaluate cognitive function among alcoholic subtypes, defined by patterns of other drug use. This analysis suggests there are significant differences in neurocognitive function among these subtypes.  相似文献

The role of memory in the Tower of London task   总被引:5,自引:0,他引:5  
The Tower of London (TOL) task is widely used as a neuropsychological test of planning. Relatively little is known of the cognitive components of the task, and in particular the role of memory in performance. The current studies on normal adults looked at the role of verbal and spatial working memory in the TOL. The effects of verbal and visuospatial dual-task manipulations on TOL performance were examined in an experiment with 36 participants. Both verbal and visuospatial executive secondary tasks caused poorer performance on the TOL; however, concurrent articulatory suppression enhanced performance. The results suggest that executive and spatial components are important in the task, and raise questions about the role of preplanning in the TOL.  相似文献

African American and White mother/adolescent pairs were examined for familial associations in body size and weight concerns. Mothers' and adolescents' estimates of adolescents' body mass index (BMI) were significantly correlated. Compared to boys, girls had greater body dissatisfaction, higher weight concerns, and perceived higher family/friend weight concerns. By race, White adolescents had more body dissatisfaction and greater concern about weight than African American adolescents. Four items explained 70.4% of the variance in adolescents' weight concern scores: adolescents' weight management practices, mothers' reports of adolescents' saying they were too fat, adolescents' perceptions of family/friends' weight concerns, and adolescents' body dissatisfaction. Our study suggests White girls are more concerned about their weight and perceive greater weight and dieting concerns among family/friends than African American girls.  相似文献

If a standard Z?llner illusion is seen as a staircase in depth, pairs of long lines flanking convex stair edges appear to diverge as usual, but divergence in pairs flanking concave edges can appear reduced. If the stair is reversed perceptually in the manner of the Schr?der staircase, convex and concave shapes exchange and the extent of apparent divergence in the long line pairs exchanges with them. The effect is enhanced if explicit stair edges are added, and reduced if the standard Z?llner pattern is replaced by one in which segments of the long lines are offset in the direction of the usual illusory effect. The observations suggest that the three-dimensional potential of the pattern cannot be excluded from explanations of the illusion, and are compatible with the view of Gregory and Harris that inappropriate constancy scaling is its primary cause, triggered 'bottom-up' by pattern properties or 'top-down' by cognitive inference. However, these two mechanisms would have to be acting in conflict to generate suppression of divergence in the concave steps. Pattern processing for properties, such as orientation, that are not associated with the potential of the Z?llner illusion as a three-dimensional configuration, but that have been suggested as sources of the illusion in recent studies, could also be acting in opposition to hypothesis scaling in the concave steps.  相似文献

This study represents an effectiveness study and service evaluation of a cognitive behavioral, couple‐based treatment for depression (BCT‐D) provided in London services that are part of the “Improving Access to Psychological Therapies” (IAPT) program in England. Twenty‐three therapists in community clinics were trained in BCT‐D during a 5‐day workshop, followed by monthly group supervision for 1 year. The BCT‐D treatment outcome findings are based on 63 couples in which at least one partner was depressed and elected to receive BCT‐D. Eighty‐five percent of couples also demonstrated relationship distress, and 49% of the nonclient partners also met caseness for depression or anxiety. Findings demonstrated a recovery rate of 57% with BCT‐D, compared to 41% for all IAPT treatments for depression in London. Nonclient partners who met caseness demonstrated a 48% recovery rate with BCT‐D, although they were not the focus of treatment. BCT‐D was equally effective for clients regardless of the clinical status of the nonclient partner, suggesting its effectiveness in assisting both members of the couple simultaneously. Likewise, treatment was equally effective whether or not both partners reported relationship distress. The findings are promising regarding the successful application of BCT‐D in routine clinical settings.  相似文献

Despite menstruation being a physiological phenomenon in women’s life, social research has highlighted that there are still many taboos, also conveyed by advertising, which prevent an open discourse on the topic and can have negative impacts on women’s well-being. The present study examined the influence of the exposure to existing TV advertisements for sanitary napkins depicting menstruation as a taboo on self-objectification in women from Italy (n = 160) and Sweden (n = 159). To do so, we also investigated the moderating role of menstrual knowledge in this relationship. Our findings showed that in the Italian sample, exposure to the taboo TV commercial led to more self-objectification especially for participants with lower knowledge of menstruation. These effects did not occur for their Swedish counterparts, showing no differences in self-objectification when women were exposed to the taboo advertisement. The present results are discussed in light of cultural differences in sexual and menstrual education between the two countries. Theoretical and practical implications are drawn.  相似文献
