Optimism and pessimism are personality variables that have repeatedly been shown to affect health, job performance, and social
relationships. Various instruments purport to measure these dispositions that differ substantially in their theoretical and
measurement models. While research has examined relations between subsets of these measures, their unique predictive ability
has been neglected. Three sequential studies evaluated the interrelation and predictive ability of the three most utilized
instruments, the Life Orientation Test (LOT), the O/P Instrument (OPI) and variants of the Attributional Style Questionnaire
(ASQ). Consistent with expectations, measures sharing a future-expectancy component (LOT and OPI) were moderately related
and most predictive of health, depression, and coping. ASQ measures were modestly related to the LOT and OPI and offered less
consistent predictions. 相似文献

This article describes the development and psychometric properties of an inventory to assess cognitive appraisal of the Department of Veterans Affairs (VA) disability application process, the Disability Application Appraisal Inventory (DAAI). Participants were 439 veterans seeking disability status for posttraumatic stress disorder through the VA and subgroups from that sample. The 3 DAAI scales assess (a) understanding of the disability application process (Knowledge scale) (b) expectations specific to the process (Negative Expectations scale) and (c) investment in obtaining disability status (Importance scale). The scales are internally consistent and largely uncorrelated. Test-retest correlations are adequate for the Negative Expectations and Importance scales. Evidence of factorial and construct validity is presented. 相似文献

The role of the hippocampus in object recognition memory processes is unclear in the current literature. Conflicting results have been found in lesion studies of both primates and rodents. Procedural differences between studies, such as retention interval, may explain these discrepancies. In the present study, acute lidocaine administration was used to temporarily inactivate the hippocampus prior to training in the spontaneous object recognition task. Male C57BL/6J mice were administered bilateral lidocaine (4%, 0.5 microl/side) or aCSF (0.5 microl/side) directly into the CA1 region of the dorsal hippocampus 5 min prior to sample object training, and object recognition memory was tested after a short ( 5 min) or long (24 h) retention interval. There was no effect of intra-hippocampal lidocaine on the time needed for mice to accumulate sample object exploration, suggesting that inactivation of the hippocampus did not affect sample session activity or the motivation to explore objects. Lidocaine-treated mice exhibited impaired object recognition memory, measured as reduced novel object preference, after a 24 h but not a 5 min retention interval. These data support a delay-dependent role for the hippocampus in object recognition memory, an effect consistent with the results of hippocampal lesion studies conducted in rats. However, these data are also consistent with the view that the hippocampus is involved in object recognition memory regardless of retention interval, and that object recognition processes of parahippocampal structures (e.g., perirhinal cortex) are sufficient to support object recognition memory over short retention intervals. 相似文献

Dynamical, self-organizing models of sentence processing predict "digging-in" effects: The more committed the parser becomes to a wrong syntactic choice, the harder it is to reanalyze. Experiment 1 replicates previous grammaticality judgment studies (F. Ferreira & J. M. Henderson, 1991b, 1993), revealing a deleterious effect of lengthening the ambiguous region of a garden-path sentence. The authors interpret this result as a digging-in effect. Experiment 2 finds a corresponding effect on reading times. Experiment 3 finds that making 2 wrong attachments is worse than making 1. Non-self-organizing models require multiple stipulations to predict both kinds of effects. The authors show that, under an appropriately formulated self-organizing account, both results stem from self-reinforcement of node and link activations, a feature that is needed independently. An implemented model is given. 相似文献

Over the past decade, behavior analysts have increasingly used the term establishing operation (EO) to refer to environmental events that influence the behavioral effects of operant consequences. Nonetheless, some elements of current terminology regarding EOs may interfere with applied behavior analysts' efforts to predict, control, describe, and understand behavior. The present paper (a) describes how the current conceptualization of the EO is in need of revision, (b) suggests alternative terms, including the generic term motivating operation (MO), and (c) provides examples of MOs and their behavioral effects using articles from the applied behavior analysis literature. 相似文献

"I know you self-handicapped last exam": gender differences in reactions to self-handicapping 总被引:5,自引:0,他引:5
Past research has shown that self-handicapping involves the trade-off of ability-related attributional benefits for interpersonal costs. Study 1 examined whether perceiver or target sex moderates impressions of self-handicapping targets. Although target sex was not an important factor, female perceivers were consistently more critical of behavioral self-handicappers. Two additional studies replicated this gender difference with variations of the handicap. Study 3 examined the motives inferred by perceivers and found that women not only view self-handicappers as more unmotivated but also report greater suspicion of self-handicapping motives; furthermore, these differences in perceived motives mediated sex differences in reactions to self-handicappers. Implications for the effectiveness of self-handicapping as an impression management strategy are discussed. 相似文献

Aydin and colleagues reported a reversal of physiological 'right-ear advantage' in a group of right-handed patients with schizophrenia, using an auditory acuity test. In schizophrenia, auditory hallucinations may appear to be spatially located inside or outside the patient's head. Here we show, using virtual acoustic space techniques, that normal right-handed subjects have a right-ear advantage for correctly locating the 'source' of hallucination-like voices as from either inside or outside the head. We propose a model for understanding lateralised, external hallucinations in schizophrenia based upon reversal of normal cortical asymmetry for auditory spatial processing. 相似文献

Spatial diagram representations such as hierarchies, matrices, and networks are important tools for thinking. Our data suggest that college students possess abstract schemas for these representations that include at least rudimentary information about their applicability conditions. In Experiment 1, subjects were better able to select the appropriate spatial diagram representation for a problem when cued to use general category information in memory about those representations than when cued to use specific example problems given during the experiment. The results of Experiment 2 showed that the superior performance in the general category condition was not based on a comparison of the test problems with examples in memory. The results of Experiment 3 showed that the superior performance was not due to learning that occurred during the experiment or to transfer appropriate processing. The General Discussion section considers the nature of students' representation schemas and the question of why college students have only rudimentary schemas for common and widely applicable diagrammatic representations. 相似文献
