This research is an examination of whether cognition in depressed individuals incorporates a realistic view of the world or a general tendency toward negativity. Participants provided two types of probability judgments of the likelihood that they correctly answered general knowledge questions: the probability that they correctly answered each of the individual questions and an aggregate judgment, after completing the questionnaire, of the percentage of all the questions they thought they had correctly answered. These tasks generally elicit overconfidence and accuracy in nondepressives. In accord with theories of both depressive realism and general negativity, in their item-by-item assessments of their answers to the individual questions, depressed participants demonstrated less overconfidence than nondepressed participants. In accord with the theory of general negativity but not with the theory of depressive realism, however, depressed participants demonstrated underconfidence in their aggregate judgments. The implications of these findings on theories of depressive cognition are discussed. 相似文献

Multiple membership random effects models (MMREMs) have been developed for use in situations where individuals are members of multiple higher level organizational units. Despite their availability and the frequency with which multiple membership structures are encountered, no studies have extended the MMREM approach to hierarchical growth curve modeling (GCM). This study introduces a cross-classified multiple membership growth curve model (CCMM-GCM) for modeling, for example, academic achievement trajectories in the presence of student mobility. Real data are used to demonstrate and compare growth curve model estimates using the CCMM-GCM and a conventional GCM that ignores student mobility. Results indicate that the CCMM-GCM represents a promising option for modeling growth for multiple membership data structures. 相似文献

Discounting is a useful framework for understanding choice involving a range of delayed and probabilistic outcomes (e.g., money, food, drugs), but relatively few studies have examined how people discount other commodities (e.g., entertainment, sex). Using a novel discounting task, where the length of a line represented the value of an outcome and was adjusted using a staircase procedure, we replicated previous findings showing that individuals discount delayed and probabilistic outcomes in a manner well described by a hyperbola-like function. In addition, we found strong positive correlations between discounting rates of delayed, but not probabilistic, outcomes. This suggests that discounting of delayed outcomes may be relatively predictable across outcome types but that discounting of probabilistic outcomes may depend more on specific contexts. The generality of delay discounting and potential context dependence of probability discounting may provide important information regarding factors contributing to choice behavior. 相似文献

Forgetting over the short term has challenged researchers for more than a century, largely because of the difficulty of controlling what goes on within the memory retention interval. But the “recent-negative-probe” procedure offers a valuable paradigm, by examining the influences of (presumably) unattended memoranda from prior trials. Here we used a recent-probe task to investigate forgetting for visual nonverbal short-term memory. The target stimuli (two visually presented abstract shapes) on a trial were followed after a retention interval by a probe, and participants indicated whether the probe matched one of the target items. Proactive interference, and hence memory for old trial probes, was observed, whereby participants were slowed in rejecting a nonmatching probe on the current trial that nevertheless matched a target item on the previous trial (a recent-negative probe). The attraction of the paradigm is that, by uncovering proactive influences of past-trial probe stimuli, it can be argued that active maintenance in memory of those probes is unlikely. In two experiments, we recorded such proactive interference of prior-trial items over a range of interstimulus (ISI) and intertrial (ITI) intervals (between 1 and 6 s, respectively). Consistent with a proposed two-process memory conception (the active–passive memory model, or APM), actively maintained memories on current trials decayed, but passively “maintained,” or unattended, visual memories of stimuli on past trials did not. 相似文献

Hope is believed to be influential to therapeutic change. However, no studies have explored couples’ experiences of hope during participation in a reflecting team process. This exploratory case study attends to this gap in the research literature. Three couples reported on their experiences of hope in relation to participating in the reflecting team process as part of their couple therapy. Themes related to hope were identified during three separate stages of the intervention: anticipating, participating in, and debriefing the reflecting team process. Reflecting team experiences related to hope included: seeking new perspectives, maintaining a positive momentum, identifying strengths, normalizing difficulties, presenting inspiring possibilities, providing support, highlighting growth, and strengthening resolve. These findings serve as a foundation for attending to clients’ hope as an active force during the reflecting team process. 相似文献

Mucopolysaccharidosis type II (MPS II), also known as Hunter syndrome, is a chronic and progressive X-linked lysosomal disease that mainly affects males. It occurs in 1 in every 65,000 to 1 in 132,000 births. There are two distinct forms of the disease based on age of onset and clinical course: mild and severe. MPS II affects many organ systems including the nervous, cardiovascular, gastrointestinal and respiratory systems. Complications can include vision problems, progressive hearing loss, thickened and elastic skin, mental impairment, and enlarged liver and spleen. We herein focus on the adaptive behavior of individuals with MPS II, and the impact of MPS II on the family system. Outcomes from the Vineland-II Adaptive Behavior Scales showed that the MPS II patient sample experienced significantly lower functioning in communication, daily living skills, socialization, and motor skills compared to normative data. Patients with severe MPS II were found to have significantly lower adaptive functioning in all domains, as compared to those with mild MPS II. Length of time on ERT had no significant relationship to adaptive functioning. Results from the Peds QL Family Impact Module indicated that families of patients with MPS II experienced a lower overall health-related quality of life and overall lower family functioning (including lower emotional and cognitive functioning) than those with chronic illnesses residing in an inpatient setting. 相似文献

This study examined the effects of a family systems therapy (Ecologically‐Based Family Therapy [EBFT]) on the co‐occurring trajectory of mothers’ substance use and psychological control, and its association with children's problem behaviors. Participants included 183 mothers with a substance use disorder who had at least one biological child in their care. Mothers were randomly assigned to one of the three intervention conditions: EBFT—home, n = 62; EBFT—office, n = 61; or Women's Health Education, n = 60. Participants were assessed at baseline, 3, 6, 12, and 18 months post‐baseline. A dual‐trajectory class growth analysis identified three groups of mothers in regard to their change trajectories. The majority of the mothers exhibited a synchronous decrease in substance use and psychological control (n = 107). In all, 46 mothers exhibited a synchronous increase in substance use and psychological control. For the remaining 30 mothers, substance use and psychological control remained stable. Mothers in the family therapy condition were more likely to show reduced substance use and psychological control compared to mothers in the control condition. Moreover, children with mothers who showed decreased substance use and psychological control exhibited lower levels of problem behaviors compared to children with mothers showing increased substance use and psychological control. The findings provide evidence for the effectiveness of family systems therapy, EBFT, in treating mothers’ substance use, improving parenting behaviors, and subsequently improving child behavioral outcomes. 相似文献
