Health-related quality of life (HRQOL) in substance abusers remains an area of inquiry in need of investigation. The few studies
on the topic have found substance abuser HRQOL less than that of the general population. The present research compared 303
substance abusers in long-term residential therapeutic community treatment in New York with a general non-institutionalized
adult sample from New York (N = 27,465) whose data were collected between 2002 and 2006 during the yearly administrations of the Behavioral Risk Factor
Surveillance System (BRFSS), a state-based system of health surveys gathering data from upwards of 350,000 adults per year
across all 50 states. One sample t-tests found that the in-treatment substance abusers reported significantly more physically
and mentally unhealthy days over the past 30 days, as well as significantly more inactive days over the past 30 days due to
illness. 相似文献

We compared the ability of auditory, visual, and audiovisual (bimodal) exogenous cues to capture visuo-spatial attention under conditions of no load versus high perceptual load. Participants had to discriminate the elevation (up vs. down) of visual targets preceded by either unimodal or bimodal cues under conditions of high perceptual load (in which they had to monitor a rapidly presented central stream of visual letters for occasionally presented target digits) or no perceptual load (in which the central stream was replaced by a fixation point). The results of 3 experiments showed that all 3 cues captured visuo-spatial attention in the no-load condition. By contrast, only the bimodal cues captured visuo-spatial attention in the high-load condition, indicating for the first time that multisensory integration can play a key role in disengaging spatial attention from a concurrent perceptually demanding stimulus. 相似文献

Resurgence refers to an increase in a previously suppressed target behavior with a relative worsening of conditions for a more recently reinforced alternative behavior. This experiment examined the relation between resurgence and the magnitude of a reduction in the rate of reinforcement for the alternative behavior. Groups of both male and female rats initially pressed a target lever for food on a variable-interval (VI) 30-s schedule. In a second phase, responding to the target lever was extinguished for all groups and pressing an alternative lever was reinforced on a VI 10-s schedule. Next, the rate of reinforcement for alternative behavior was reduced differentially across groups by arranging extinction, VI 80-s, VI 40-s, VI 20-s, or continued VI 10-s reinforcement. Target responding increased as an exponential function of the magnitude of the reduction in alternative reinforcement rates. With the exception that males appeared to show higher rates of target responding in baseline and higher rates of alternative responding in other phases, the overall pattern of responding across phases was not meaningfully different between sexes. The pattern of both target and alternative response rates across sessions and phases was well described quantitatively by the Resurgence as Choice in Context model. 相似文献

Although studies have shown that the self-efficacy–performance relationship can be studied within performances (LaForge & Sullivan, 2010), no studies have directly compared noncontinuous (i.e., between performances) and continuous (i.e., within performances) conditions. The present study examined the efficacy–performance relationship within a continuous task and between a noncontinuous sport conditions. Path analyses revealed reciprocal efficacy–performance relationships in both the continuous and noncontinuous conditions, with higher goodness of fit indicators in the noncontinuous condition and a higher number of significant pathways in the continuous condition. These results imply potential differences in the cognitive processing of efficacy information between and within sport performances. 相似文献

The best format in which information that has to be recalled is presented has been investigated in several studies, which
focused on the impact of bimodal stimulation on working memory performance. An enhancement of participant’s performance in
terms of correct recall has been repeatedly found, when bimodal formats of presentation (i.e., audiovisual) were compared
to unimodal formats (i.e, either visual or auditory), in providing implications for multimedial learning. Several theoretical
frameworks have been suggested in order to account for the bimodal advantage, ranging from those emphasizing early stages
of processing (such as automatic alerting effects or multisensory integration processes) to those centred on late stages of
processing (as postulated by the dual coding theory). The aim of this paper is to review previous contributions to this topic,
providing a comprehensive theoretical framework, which is updated by the latest empirical studies. 相似文献

Resurgence refers to the recurrence of an extinguished target behavior following subsequent suspension of alternative reinforcement. Delivery of reinforcers during extinction of alternative behavior has been shown to mitigate resurgence. The present experiment aimed to determine whether delivering stimuli associated with reinforcers during resurgence testing similarly mitigates resurgence. Three groups of rats pressed target levers for food according to variable‐interval 15‐s schedules during Phase 1. In Phase 2, lever pressing was extinguished, and an alternative nose‐poke response produced alternative reinforcement according to a variable‐interval 15‐s schedule. Food reinforcement was always associated with illumination of the food aperture and an audible click from the pellet dispenser during Phases 1 and 2. Phase 3 treatments differed between groups. For one group, nose poking continued to produce food and food‐correlated stimuli. Both of these consequences were suspended for a second group. Finally, nose poking produced food‐correlated stimuli but not food for a third group. Target‐lever pressing resurged in the group that received no consequences and in the group that received only food‐correlated stimuli for nose poking. Resurgence, however, was smaller for the group that received food‐correlated stimuli than for the group that received no consequences for nose poking. Target‐lever pressing did not increase between phases in the group that continued to receive food and associated stimuli. Thus, delivery of stimuli associated with food reinforcement after suspension of food reduced but did not eliminate resurgence of extinguished lever pressing. These findings contribute to potential methodologies for preventing relapse of extinguished problem behavior in clinical settings. 相似文献

For the many older adults living in long-term care facilities, the ability to connect with others, as well as with one’s own personal past, may be of particular value. Reflecting on the past and sharing reminiscences with others serves different psychosocial functions in various settings. This study examined the functions of reminiscence for long-term care residents in the United States (Mage?=?86.5) by addressing the self-reported frequency of reminiscence, the counterparties involved, the overall purpose and value of reminiscence, and the relation to residents’ mental health and well-being. Results demonstrated that although some functions of reminiscence were comparable to those found in community-dwelling older adults, others were unique to the long-term care setting. Residents were most likely to reminisce alone and they found the experience enjoyable. They reported engaging in and enjoying reminiscence with family more than with fellow residents, and a subset desired increased opportunities to share memories with healthcare providers. Residents with lower morale and more depressive symptoms were more likely to engage in unhealthy styles of reminiscence. These findings suggest that interventions shaping reminiscence encounters may have positive outcomes for long-term care residents. 相似文献

Clark and Chalmers (1998) have argued that mental states can be extended outside an organism's skin. In response to some worries about the availability, reliability and portability of such extended resources, Clark (2005) offers a set of rough criteria that non-biological objects must fulfil to legitimately ground mental states. One such criterion is that the information retrieved from these non-biological sources be (more or less) automatically endorsed. But Sterelny (2003, 2005) has persuasively argued that the extended sphere is epistemologically opaque: a domain of contested truth and deliberate deception. As such, retrieving information from this domain requires the deployment of social guards for the information to remain reliable. But deploying such guards would seem to endanger endorsability by increasing cognitive load. Here I demonstrate that deploying social guards does not increase cognitive load if the guards are implemented in a highly distributed connectionist economy or off-loaded to the external environment. 相似文献

In addition to providing robust cues diagnostic of prospective mates' heritable fitness, various physical features could be similarly utilized in inferring individuals' parental abilities. This study sought to explore how variations in sexually dimorphic facial features inform perceptions of social targets as motivated to provide parental care. American undergraduates (N = 244) viewed a series of 12 total male and female faces manipulated at varying degrees of sex-typicality (i.e., masculinized versus feminized versus unaltered controls) on a within-subjects basis, and rated the perceived motivation of each target to nurture and protect a child using items derived from the Parental Care and Tenderness Scale. Female targets were perceived as more motivated by parental care than male targets, F(1, 240) = 14.86, p < .001, ηp2 = 0.058, whereas male targets were perceived as specifically motivated to protect offspring, F(1, 240) = 177.32, p < .001, ηp2 = 0.425. Feminized targets were additionally perceived as more motivated by nurturance, though such inferences were apparent for both male and female targets, F(1, 240) = 7.36, p < .001, ηp2 = 0.058. Findings represent an understanding of perceivers use of functional heuristics of sexual dimorphism in identifying optimal parents. 相似文献

Within contemporary developmental science, models derived from relational developmental systems metatheory emphasize that the basic process involved in the ontogeny of civic engagement involves mutually-influential and beneficial relations between the developing individual and his or her complex and changing social, cultural, and physical contexts (represented as individual ← → context relations). The authors suggest that research on the development of civic engagement should be theoretically predicated, use change-sensitive, longitudinal methods, and be comparative across time and place. Using these facets of scholarship as a lens, we discuss the contributions to this special issue. We conclude that the present set of studies provides a useful basis for future research and applications aimed at understanding and promoting individuals’ civic contributions, and their support of social organizations promoting individual thriving and freedom, liberty, and social justice. 相似文献
