Effects of task performance, helping, voice, and organizational loyalty on performance appraisal ratings

Despite the fact that several studies have investigated the relationship between organizational citizenship behavior and performance appraisal ratings, the vast majority of these studies have been cross-sectional, correlational investigations conducted in organizational settings that do not allow researchers to establish the causal nature of this relationship. To address this lack of knowledge regarding causality, the authors conducted 2 studies designed to investigate the effects of task performance, helping behavior, voice, and organizational loyalty on performance appraisal evaluations. Findings demonstrated that each of these forms of behavior has significant effects on performance evaluation decisions and suggest that additional attention should be directed at both voice and organizational loyalty as important forms of citizenship behavior aimed at the organization.     

Temperament Pathways to Childhood Disruptive Behavior and Adolescent Substance Abuse: Testing a Cascade Model

Temperament traits may increase risk for developmental psychopathology like Attention-Deficit/Hyperactivity Disorder (ADHD) and disruptive behaviors during childhood, as well as predisposing to substance abuse during adolescence. In the current study, a cascade model of trait pathways to adolescent substance abuse was examined. Component hypotheses were that (a) maladaptive traits would increase risk for inattention/hyperactivity, (b) inattention/hyperactivity would increase risk for disruptive behaviors, and (c) disruptive behaviors would lead to adolescent substance abuse. Participants were 674 children (486 boys) from 321 families in an ongoing, longitudinal high risk study that began when children were 3 years old. Temperament traits assessed were reactive control, resiliency, and negative emotionality, using examiner ratings on the California Q-Sort. Parent, teacher, and self ratings of inattention/hyperactivity, disruptive behaviors, and substance abuse were also obtained. Low levels of childhood reactive control, but not resiliency or negative emotionality, were associated with adolescent substance abuse, mediated by disruptive behaviors. Using a cascade model, family risk for substance abuse was partially mediated by reactive control, inattention/hyperactivity, and disruptive behavior. Some, but not all, temperament traits in childhood were related to adolescent substance abuse; these effects were mediated via inattentive/hyperactive and disruptive behaviors.

Crossover by Line Length and Spatial Location

It is well known that line length has a systematic influence on line bisection error in neglect. Most patients with neglect misbisect long lines on the same side of true center as their brain lesion but then cross over on short lines, misbisecting them on the opposite side (i.e., crossover by line length). What is less recognized is that the spatial location of lines relative to the viewer can similarly induce a crossover effect when one considers line bisection error scores that have been averaged across individual line lengths. Patients with right hemisphere injury and neglect classically make averaged line bisection errors that fall right of true center on lines located either at midline or to the left of the viewer; however, we observed that the averaged line bisection error can fall left of true center when lines are located to the right of the viewer (i.e., crossover by spatial location). We hypothesized that crossover by both line length and spatial location stem from systematic errors in magnitude estimation, i.e., perceived line length. We tested predictions based on this hypothesis by examining how the crossover effect by line length is altered by the spatial location of lines along a horizontal axis relative to the viewer. Participants included patients with unilateral lesions of the right and left cerebral hemispheres and age-appropriate normal subjects. All groups demonstrated a crossover effect by line length at the midline location but the effect was altered by placing lines to the right and left of the viewer. In particular, patients with right hemisphere injury and neglect crossed-over across a broader range of line lengths when the lines were located to the right of the viewer rather than at either midline or left of the viewer. It is proposed that mental representations of stimulus magnitude are altered in neglect, in addition to mental representations of space, and that traditional accounts of neglect can be enhanced by including the psychophysical concept of magnitude estimation.     

Work environment structure and psychological ownership: the mediating effects of control

Current theorists on the psychology of possession highlight control as an important route in the development of feelings of ownership. In the present article, the authors hypothesized that the extent to which individuals experience control over their job and work environment is positively associated with feelings of ownership for their job and the organization. The authors used supervisory report data on work environment structure and self-reports on experienced control and psychological ownership to test for the mediating effects of experienced control in the relationship between the work environment structure and psychological ownership. The authors found that experienced control mediates the relationship between 3 sources of work environment structure--technology, autonomy, and participative decision making--and psychological ownership of the job and (to a lesser extent) the organization. The authors proposed implications of the findings and directions of further research.     

Understanding team adaptation: a conceptual analysis and model

This endeavor provides a multidisciplinary, multilevel, and multiphasic conceptualization of team adaptation with theoretical roots in the cognitive, human factors, and industrial-organizational psychology literature. Team adaptation and the emergent nature of adaptive team performance are defined from a multilevel, theoretical standpoint. An input-throughput-output model is advanced to illustrate a series of phases unfolding over time that constitute the core processes and emergent states underlying adaptive team performance and contributing to team adaptation. The cross-level mixed-determinants model highlights team adaptation in a nomological network of lawful relations. Testable propositions, practical implications, and directions for further research in this area are also advanced.     

Incorporating adolescent females' perceptions of their partners' attitudes toward condoms into a model of female adolescent condom use

The highest rates of sexually transmitted infections in the U.S. occur among adolescent females. One prevention strategy promoted for sexually active adolescents is condom use: therefore, influences on correct and consistent condom use are worth examining. Because interventions and observational research into predicting and increasing condom use have yielded mixed results, we hypothesized that a theoretically driven model incorporating female adolescents' perceptions about partner sentiments along with their own perceptions, intentions, and behaviours would improve condom use predictions. We also measured condom use errors and consistency for a more precise estimate of effective use than is common in the literature. In three structural equation models tested on a sample of 519 female adolescents, we found that intentions were associated with both correct and consistent condom use; that females' expectancy beliefs about condom use were associated with intentions; and that females' expectancy beliefs about partners' sentiments reduced the impact of their expectancy beliefs about condom use. The implications of these relations upon condom use correctness and consistency are discussed with respect to informing interventions, among other future research.     

Meadow voles, Microtus pennsylvanicus, can distinguish more over-marks from fewer over-marks

Is it possible that voles have a sense of number? To address this question, we determined whether voles discriminate between two different scent-marking individuals and identify the individual whose scent marks was on top more often than the other individual. We tested whether voles show a preference for the individual whose scent marks was on top most often. If so, the simplest explanation was that voles can make a relative size judgement—such as distinguishing an area containing more of one individual’s over-marks as compared to less of another individual’s over-marks. We found that voles respond preferentially to the donor that provided a greater number of over-marks as compared to the donor that provided a lesser number of over-marks. Thus, we concluded that voles might display the capacity for relative numerousness. Interestingly, female voles were better able than male voles to distinguish between small differences in the relative number of over-marks by the two scent donors.     

Social identity complexity and outgroup tolerance

Social identity complexity refers to the way in which individuals subjectively represent the relationships among their multiple ingroup memberships. More specifically, individuals with low social identity complexity see their ingroups as highly overlapping and convergent, whereas those with high complexity see their different ingroups as distinct and cross-cutting membership groups. The present study tested the hypothesis that perceived overlap among ingroup memberships would be negatively related to ingroup inclusiveness and tolerance for outgroups, such that individuals with high overlap (low complexity) would be less tolerant and accepting of outgroups in general than those with low overlap (high complexity). Results from a telephone interview survey of adult residents of the state of Ohio supported this hypothesis. Individual differences in complexity of perception of their national, religious, occupational, political, and recreational social identities were systematically related to their attitudes toward ethnic outgroups and diversity.     

Who Will Volunteer? Religiosity, Everyday Racism, and Social Participation Among African American Men

This study explores the relative importance of everyday racism, empathic concern, communalism, and religiosity as predictors of pro-social involvement (i.e., volunteerism and membership in political/social justice organizations) among a sample of African American men (N = 151). Church involvement emerged as a positive predictor of the likelihood that these men were involved in volunteer work as well as the number of hours that men dedicated to volunteer work. Communalism positively predicted the amount of time (in hours per year) that men were involved in volunteer work. Subjective religiosity and the stress of everyday racism were associated with a greater likelihood of being a member of a political–social justice organization. Implications of these findings are discussed.     

Eliciting and comparing false and recovered memories: an experimental approach

We describe an experimental paradigm designed to elicit both recovered and false memories in the laboratory. All participants saw, on a video screen, three critical categorized lists of words mixed in randomly with eighteen filler categorized lists. Those in the blocking condition then had several paper‐and‐pencil tasks that involved only the 18 non‐critical filler lists. An uncued recall test was then given, asking participants to recall all the lists they originally saw on the video screen. Finally, there was a cued recall test that provided category cues for the three critical lists. Substantial memory blocking of critical lists on the uncued test and recovery on the cued recall test was observed in all three experiments. In Experiments 2 and 3, many false and recovered memories were elicited on the cued recall test by including cues for the three critical (forgotten) lists, plus cues for three lists that had never been presented. False memories were distinguishable from truly recovered memories in cued recall by ‘know’ versus ‘remember’ judgements, and by confidence ratings; accurately recovered memories were associated with higher confidence. False and recovered memories could not be discriminated based on recall latency. The results repeatedly show powerful effects of memory blocking and recovery. We also show that recovered and false memories can be elicited within a single experimental procedure, and there may be unique characteristics of each. Although we urge caution in generalizing to false and recovered memories of trauma, we suggest that variations of our comparative memory paradigm may be useful for learning about such phenomena.
