Individuals with obsessive-compulsive disorder (OCD) often report compulsions aimed at reducing feelings of something not being just right or sensations of incompleteness. Research using self-report questionnaires has demonstrated a link between not just right experiences (NJREs) and OCD symptoms (Behav. Res. Therapy 41 (2003) 681; Anxiety, 1 (1995) 208). Extending previous work, this paper presents experimental and self-monitoring data on NJREs in an undergraduate sample. NJREs produced distress and urges to change something, but feared consequences were rare. Stronger responses were found for naturally occurring self-monitored NJREs compared to NJREs elicited in the laboratory. Several significant relationships were found between features of NJREs and OC symptoms and constructs theoretically related to OCD (e.g., responsibility, incompleteness), but no significant relationships were found between features of NJREs and non-OCD-related constructs (worry, depressive symptoms, social anxiety). Further consideration of NJREs will be useful in improving our understanding of the phenomenology, neurobiological substrates, and treatment, of OCD. 相似文献

Loren and Jean Chapman highlighted the importance that the psychometric characteristics of a task may have when comparing different populations (L. J. Chapman & J. P. Chapman, 1973, 1978). Specifically, they pointed out that when comparing 2 tasks measuring different constructs, there is a greater likelihood of finding larger deficits on a task with higher discriminating power, irrespective of what the task measures. While researchers have addressed this issue, they typically have assumed that more difficult tasks have greater discriminating power, often without actually measuring discriminating power. In this article, the authors present data from 2 studies using phonologic and category fluency tasks to demonstrate that the critical factor for task selection and matching is discriminating power, not task difficulty. 相似文献

For multiple populatios, a longtidinal factor analytic model which is entirely exploratory, that is, no explicit identification constraints, is proposed. Factorial collapse and period/practice effects are allowed. An invariant and/or stationary factor pattern is permitted. This model is formulated stochastically. To implement this model a stagewise EM algorithm is developed. Finally a numerical illustration utilizing Nesselroade and Baltes' data is presented.The authors wish to thank Barbara Mellers and Henry Kaiser for their helpful comments and John Nesselroade for providing us the data for our illustration. This research wwa supported in part by a grant (No. AG03164) from the National Institute on Aging to William Meredith. Details of the derivations and a copy of the PROC MATRIX program are available upon request from the first author. 相似文献

Marketing has long rested on the use of market segmentation. While birth age has been a useful way to create groups, it describes segments but in itself does not help to understand segment motivations. Environmental events experienced during one's coming‐of‐age years, however, create values that remain relatively unchanged throughout one's life. Such values provide a common bond for those in that age group, or cohort. Segmenting by ‘coming‐of‐age’ age provides a richer segmentation approach than birth age. This approach, known to work in America, is used in this paper to create generational cohorts in Russia and in Brazil. Copyright © 2004 Henry Stewart Publications Ltd. 相似文献

The current study tests whether propositions set forth in an evolutionary model of temperament (Korte, Koolhaas, Wingfield, & McEwen, 2005) may enhance our understanding of children's differential susceptibility to unsupportive and harsh caregiving practices. Guided by this model, we examined whether children's behavioral strategies for coping with threat and challenge cohered into 2 broad, phenotypic dimensions--hawk and dove--that have been maintained by frequency-dependent selection throughout our ancestral history: Hawk-like strategies are characterized by approach, dominant-negative affect, and activity, whereas dove-like strategies are evidenced by avoidance, inhibition, and vulnerable affect. In turn, we examined the moderating effect of hawk or dove profile membership on children's physiological and psychological adaptation to harsh rearing environments. Participants included 201 2-year-old toddlers and their mothers. Consistent with the Korte model, latent profile analyses extracted 2 profiles that cohered into hawk and dove strategies. Children were classified within hawk or dove profiles and separately examined in a process model of harsh caregiving. As predicted, associations between harsh caregiving practices and children's basal cortisol, parasympathetic nervous system, and sympathetic nervous system activity were moderated by profile membership. In turn, basal physiological levels were differentially predictive of children's psychological adaptation over time. Collectively, findings highlight the potential value of translating the study of evolutionary models to understanding developmental outcomes associated with harsh caregiving. 相似文献

Theoretical models of social phobia propose that biased attention contributes to the maintenance of symptoms; however these theoretical models make opposing predictions. Specifically, whereas Rapee and Heimberg (1997) suggested the biases are characterised by hypervigilance to threat cues and difficulty disengaging attention from threat, Clark and Wells (1995) suggested that threat cues are largely avoided. Previous research has been limited by the almost exclusive reliance on behavioural response times to experimental tasks to provide an index of attentional biases. The current study evaluated the relationship between the time-course of attention and symptoms of social anxiety and depression. Forty-two young adults completed a dot-probe task with emotional faces while eye-movement data were collected. The results revealed that increased social anxiety was associated with attention to emotional (rather than neutral) faces over time as well as difficulty disengaging attention from angry expressions; some evidence was found for a relationship between heightened depressive symptoms and increased attention to fear faces. 相似文献

A visual world experiment examined the time course for pragmatic inferences derived from visual context and contrastive intonation contours. We used the construction It looks like an X pronounced with either (a) a H* pitch accent on the final noun and a low boundary tone, or (b) a contrastive L + H* pitch accent and a rising boundary tone, a contour that can support contrastive inference (e.g., It LOOKSL+H*like a zebraL-H%… (but it is not)). When the visual display contained a single related set of contrasting pictures (e.g. a zebra vs. a zebra-like animal), effects of LOOKSL+H* emerged prior to the processing of phonemic information from the target noun. The results indicate that the prosodic processing is incremental and guided by contextually-supported expectations. Additional analyses ruled out explanations based on context-independent heuristics that might substitute for online computation of contrast. 相似文献
