Suicide and prostitution among street youth: a qualitative analysis

This study presents the results of a qualitative analysis of the narratives of 29 street youth in which they describe their experiences with, and understanding of, suicide. A history of attempted suicide was reported by 76% of the participants and the analysis revealed themes of isolation, rejection/betrayal, lack of control, and most centrally, low self-worth as forming the basis of their experiences concerning suicide. Additionally it was found that trading sex, in which most participants had been or were currently involved, was linked with their suicidal experiences and may account for the high attempt rate. Finally, variables related to suicide were found that have not been examined previously in the literature on street youth, including loss of control, assault during prostituted sex, drug abuse as a "slow suicide," and breakups in intimate relationships.     

Perceived corporate ethical values and individual cynicism of working students

This study explored a proposed relationship between the corporate ethical values and cynicism of 195 working students. Analysis indicated students' perceived ethical values were negatively related to individual cynicism after accounting for several variables.     

Convergence and predictive validity in measures of optimism and pessimism: Sequential studies

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.     

Development and psychometric properties of the disability application appraisal inventory

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.     

Evidence for self-organized sentence processing: digging-in effects

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.     

Motivating operations and terms to describe them: some further refinements

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.     

"I know you self-handicapped last exam": gender differences in reactions to self-handicapping

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.     

Laterality effects in perceived spatial location of hallucination-like voices

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.     

Evidence for abstract, schematic knowledge of three spatial diagram representations

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.
