PERCEIVED INGROUP AND OUTGROUP PREFERENCE: A LONGITUDINAL CAUSAL INVESTIGATION

Although there has been substantial research on perceptions of preference in hiring, there is considerably less focus on perceptions of preference in organizational activities more generally. Researchers seldom assess perceptions of preference for both historically high- and low-status groups and for both one's own group and others. Using a three-wave longitudinal survey of 1,094 employees, the causal direction between perceived preference and satisfaction with management, moderators of that relationship, and whether responses to perceived preference differed by group were examined. On average, groups perceived more outgroup than ingroup preference. The satisfaction to perceived preference causal direction was significantly stronger than the reverse for outgroup preference, suggesting that increased satisfaction with management leads to decreased future perceptions of outgroup preference more so than vice versa. The relationship between satisfaction with management and perceived outgroup preference was moderated by perceived organizational tolerance of discrimination, suggesting that positive diversity climate can alleviate the negative effects of dissatisfaction with management on perceived outgroup preference.     

Choice: Some quantitative relations

Six pigeons responded in fifty-six conditions on a concurrent-chains procedure. Conditions included several with equal initial links and unequal terminal links, several with unequal initial links and equal terminal links, and several with both unequal initial and terminal links. Although the delay-reduction hypothesis accounted well for choice when the initial links were equal (mean deviation of .04), it fit the data poorly when the initial links were unequal (mean deviation of .18). A modification of the delay-reduction hypothesis, replacing the rates of reinforcement with the square roots of these rates, fit the data better than either the unmodified delay-reduction equation or Killeen's (1982) model. The modified delay-reduction equation was also consistent with data from prior studies using concurrent chains. The absolute rates of responding in each terminal link were well described by the same hyperbola (Herrnstein, 1970) that describes response rates on simple interval schedules.     

Stable individual differences in situation-behaviour,construct-behaviour,and goal-behaviour relations

This study starts from a cognitive-social-learning conceptualization of the contribution of static person by situation interaction to overt behaviour variance. Individual differences in the relation between, on the one hand, situational variation in behaviour and, on the other hand, situational variation in objective situational characteristics, situational variation in construed situational characteristics, and situational variation in goals-in-situations were systematically investigated. Thirty-six first-year psychology students had to freely generate and briefly describe 20 interpersonal situations that they had encountered during the last year. Afterwards, they had to rate each situation for four basic behavioural continua, eight supplied objective situational characteristics, eight supplied constructs, and eight supplied goals. Correlational analysis revealed many stable individual differences, not only in degree, but also in direction (sign) of situation-behaviour, construct–behaviour, and goal–behaviour relations. These relational variables could be reduced to seven relational factorial dimensions. The theoretical and practical implications of these findings are discussed.     

Semantic classification in aphasia: A study of basic, superordinate, and function relations

Nonfluent and fluent aphasics were given classification tasks that required the aphasics to identify three kinds of relations: same basic level category, same superordinate level category, and same function. The subjects received the items in word and picture form. In addition the aphasics were required to name the items they were asked to classify. The results showed that the ability to classify is more disrupted in fluent aphasia than in nonfluent aphasia. Within fluent aphasia, the degree to which classification is disrupted is dependent upon the type of relation being tested. While the overall performance of the fluent aphasics was depressed in comparison to nonfluent aphasics, it was significantly more depressed on function relations. The ability to name an item had a significant effect on the ability to classify only for basic level items.     

Genuine power curves in forgetting: A quantitative analysis of individual subject forgetting functions

Wixted and Ebbesen (1991) showed that forgetting functions produced by a variety of procedures are often well described by the power function, at^?b, where a and b are free parameters. However, all of their analyses were based on data arithmetically averaged over subjects. R. B. Anderson and Tweney (1997) argue that the power law of forgetting may be an artifact of arithmetically averaging individual subject forgetting functions that are truly exponential in form and that geometric averaging would avoid this potential problem. We agree that researchers should always be cognizant of the possibility of averaging artifacts, but we also show that our conclusions about the form of forgetting remain unchanged (and goodness-of-fit statistics are scarcely affected by) whether arithmetic or geometric averaging is used. In addition, an analysis of individual subject forgetting functions shows that they, too, are described much better by a power function than by an exponential.     

Thinking about conditionals: A study of individual differences

Recent studies have shown the existence of two qualitatively distinct groups of people based on how they judge the probability of a conditional statement. The present study was designed to test whether these differences are rooted in distinctive means of processing conditional statements and whether they are linked to differences in general intelligence. In the study, each of 120 participants completed three separate cognitive tasks involving the processing of abstract conditional statements--the probability-of-conditionals task, the conditional truth table task, and the conditional inference task--in addition to completing a test of general intelligence (AH4). The results showed a number of predicted effects: People responding with conditional (rather than conjunctive) probabilities on the first task were higher in cognitive ability, showed reasoning patterns more consistent with a suppositional treatment of the conditional, and showed a strongly "defective" truth table pattern. The results include several novel findings and post challenges to contemporary psychological theories of conditionals.     

Understanding causal conditionals: A study of individual differences

Previous studies have suggested that a minority of university students, of lower cognitive ability, are inclined to interpret abstract conditional statements, if p then q, as if they were conjunctions: p and q. In the present study we administered the conditional truth table task to a large sample of students (n = 160), but using realistic, everyday causal conditionals. We also measured their general intelligence. While individual differences were found, these were not consistent with some participants adopting a conjunctive interpretation of such statements. Rather, it appears that students of lower cognitive ability are rather likely to assume that a conditional implies its converse, so that it means also if q then p. The results are discussed with reference to the suppositional theory of conditionals and our more general account of hypothetical thinking.     

Reproducibility of fMRI-determined language lateralization in individual subjects

This study investigated within-subject test-retest reproducibility (i.e., reliability) of language lateralization obtained with fMRI. Nine healthy subjects performed the same set of three different language tasks during two fMRI sessions on separate days (verb generation, antonym generation, and picture naming). A fourth task analysis was added in which the three tasks were analyzed conjointly (combined task analysis, CTA). The CTA targets brain areas that are commonly used in different language tasks, aiming more selectively at language-critical structures. The number of active voxels (i.e., robustness) and calculated lateralization index (LI) were compared across sessions, tasks, subjects, and two a priori defined volumes of interest (classical language regions versus whole hemisphere) for a wide range of statistical thresholds. Robustness and reliability strongly varied between task analyses. The CTA was a robust detector of language-related brain activity, in contrast to the single task approaches. The CTA and verb generation task allowed for reliable calculation of the LI. Higher thresholds yielded a clear increase in left lateralization, which was largest when calculated from active voxels in classical language regions.     

PREFERENCE FOR MOTIVATOR AND HYGIENE FACTORS IN A HYPOTHETICAL INTERVIEW SITUATION: FURTHER FINDINGS AND SOME IMPLICATIONS FOR THE EMPLOYMENT INTERVIEW

Managers, supervisory personnel, clerical workers, and high school students were administered questionnaires which asked them to indicate whether or not they would discuss various work-related factors if they were applicants in an employment interview situation. A systematic tendency was found for respondents to prefer to discuss "motivators" as opposed to "hygiene factors" as characteristics they would seek in a new job, or as reasons for dissatisfaction with a previous one. Responding to a modified version of the questionnaire, twenty professional employment interviewers indicated that it is in fact wise to emphasize motivators and deemphasize hygiene factors if the applicant's intent is to maximize the likelihood of being offered a job.     

Family members' unique perspectives of the family: examining their scope, size, and relations to individual adjustment

Using the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's "unique perspective" or nonshared, idiosyncratic view of the family. We used a modified multitrait-multimethod confirmatory factor analysis that (a) isolated for each family member's 6 reports of family dysfunction the nonshared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by 1 or more family members and (b) extracted common variance across each family member's set of nonshared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. In addition, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these "unique perspectives" reflect about the family are discussed.     

Free-operant avoidance conditioning in individual and paired human subjects

Male, medical and graduate students were subjected to a non-discriminated avoidance regimen with shock-shock and response-shock intervals of 10 sec. Using a yoked-chair procedure it was found that acquisition of the button-pressing avoidance response was influenced by the social environment in which the conditioning occurred. There was a significantly greater number of “learners” among subjects conditioned individually than among those exposed to the conditioning procedures in the presence of a second person.
