When is Nothing Something? Editorial for the Null Results Special Issue of Journal of Business and Psychology

This special issue is focused on how null results can meaningfully advance science and practice. This editorial describes some of the unique aspects of creating a special issue devoted to null results, offers opinions regarding why and under what conditions null results should be valued, and offers recommendations for key stakeholders (i.e., editors, reviewers, and authors) in the publication enterprise with respect to submitting and evaluating research with null findings. This editorial also provides summaries of the papers included in this special issue with emphasis on how they serve as example for what constitutes meaningful null results.     

Extending the Nomological Network of Assessment Center Construct Validity: Prediction of Cross-Situationally Consistent and Specific Aspects of Assessment Center Performance

The purpose of this study was to expand the nomological validity of assessment centers (ACs) by investigating predictors of cross-situationally consistent versus specific aspects of AC performance. Consistent with hypotheses, (a) Big Five personality factors predicted AC performance as it related to a cross-situationally consistent general performance factor but not as it related to exercise (i.e., situationally specific) factors, and (b) job knowledge predicted performance as it related to both the general performance factor and exercise-specific factors. Results are interpreted as they relate to the growing literature on AC construct validity.     

Friendships of aggressive youth: considering the influences of being disliked and of being perceived as popular

Past research provides conflicting evidence regarding whether aggressive youth have problems in the domain of friendship. The current study tested whether being disliked by peers exacerbates the negative effects of aggression on friendship and whether being perceived as popular by peers mitigates these damaging effects. Participants were 607 third-, fifth-, seventh-, and ninth-grade students. Support for the hypothesis that being disliked or being perceived as popular would moderate relations between aggression and friendship adjustment was found for the association between relational aggression and friendship conflict. Specifically, relational aggression was associated with having conflictual friendships for youth who were disliked but not for youth who were perceived as popular. In addition, similarity between friends was found in terms of how aggressive youth were as well as in terms of how disliked they were and how popular they were perceived to be. Implications for the well-being and development of aggressive youth are discussed.     

Depressive Symptomatology among HIV-Positive Women in the Era of HAART: A Stress and Coping Model

Objective: An enhanced stress and coping model was used to explain depression among HIV-positive women in healthcare and community settings where highly active anti-retroviral treatment (HAART) was commonplace. Method: HIV-infected women in four cities (N=978) were assessed, cross-sectionally, for mental and physical health, stress, social support, and other background factors. Results: Self-reported level of depressive symptomatology was high. Number of physical symptoms, illness intrusiveness, and perceived stress were positively associated with depressed mood, while coping self-efficacy and social support were negatively associated. Stress mediated the effect of health status on depression and coping self-efficacy mediated the effect of psychosocial resources on depression. Our enhanced stress and coping model accounted for 52% of variance in depressive symtpomatology. Conclusions: Interventions focused on improving coping self-efficacy, bolstering social supports, and decreasing stress in the lives of HIV-positive women may help to reduce the negative effects of HIV disease on mood.     

Getting by with a little help from self and others: self-esteem and social support as resources during early adolescence

Influences of social support and self-esteem on adjustment in early adolescence were investigated in a 2-year longitudinal study (N = 350). Multi-informant data (youth and parent) were used to assess both overall levels and balance in peer- versus adult-oriented sources for social support and self-esteem. Findings obtained using latent growth-curve modeling were consistent with self-esteem mediating effects of social support on both emotional and behavioral adjustment. Lack of balance in social support and self-esteem in the direction of stronger support and esteem from peer-oriented sources predicted greater levels and rates of growth in behavioral problems. Results indicate a need for process-oriented models of social support and self-esteem and sensitivity to patterning of sources for each resource relative to adaptive demands of early adolescence.     

The Logical Structure of Linguistic Commitment III Brandomian Scorekeeping and Incompatibility

Curiously, though he provides in Making It Explicit (MIE) elaborate accounts of various representational idioms, of anaphora and deixis, and of quantification, Robert Brandom nowhere attempts to lay out how his understanding of content and his view of the role of logical idioms combine in even the simplest cases of what he calls paradigmatic logical vocabulary. That is, Brandom has a philosophical account of content as updating potential – as inferential potential understood in the sense of commitment or entitlement preservation – and says that the point of logical vocabulary is to make available the expressive resources to make explicit such semantic structures as arise from discursive scorekeeping practice. Thus, one would expect an account of the updating or inferential potential of sentences involving logical vocabulary, an account which is such as to assign to those sentences the inferential significance necessary for this expressive job. In short, one would expect a semantics of logical vocabulary – &, , – in terms of the difference an assertion of a sentence involving it makes to the atomic score of a linguistic agent, and a completeness proof for the logic generated by this semantics. Despite this, no such semantics is given in MIE. It is in the current paper.     

Motivation,altruism, and generalized compliance: a field study of organizational citizenship behaviors

This study tests the relations among five sources of motivation and two organizational citizenship behaviors. 175 employees from 31 locations of two agriculturally based companies completed the Motivation Sources Inventory and were rated by their supervisors for demonstrated organizational citizenship behaviors. There were significant positive correlations for employees' Self-concept-Internal Motivation with Altruistic Behavior of employees; while employees' Self-concept-External Motivation showed a significant negative relation with Altruistic Behavior by employees. Surprisingly, no correlation between employees' Goal Internalization Motivation and Altruistic Behavior by employees was found. Interpretation of these findings and further research are suggested.     

Development and convergent validation of a methodology for estimating cross-job retraining times

Cross-jobtransferability of skills is defined in terms of the ease with which individuals can apply knowledge and skills acquired in a previous job in learning to perform a new job. This study reports the development of a prototype methodology for estimating retraining times based on analyses of transferability of skills. Using this methodology which assesses interjob similarity in task content and task learning time, times to retrain across 41 different U.S. Air Force enlisted jobs were estimated. Convergent validities of retraining time estimates were tested in terms of correlations with differences in jobs': (a) general job learning difficulty, and (b) aptitude requirements. Results supported predictions that cross-job retraining time would be longer (a)into jobs that generally aremore difficult to learn, (b)from jobs that generally areless difficult to learn, and (c) across jobs having different, rather than similar, aptitude requirements. Implications for training, human resources planning, and coping with increasingly rapid technological changes in the workplace are discussed.Research sponsored by the Air Force Office of Scientific Research/AFSC, United States Air Force, under contract F49620-87-R-0004.

How big is big? Relative and absolute properties in memory

Previous studies of semantic memory have overlooked an important distinction among so-called “property statements”. Statements with relative adjectives (e.g., Flamingos are big) imply a comparison to a standard or reference point associated with an immediate superordinate category (a flamingo is big for a bird), while the truth of statements with absolute adjectives (e.g., Flamingos are pink) is generally independent of such a standard. To examine the psychological consequences of this distinction, we asked subjects in Experiment 1 to verify sentences containing either relative or absolute adjectives embedded in either predicate-adjective (PA) constructions (e.g., A flamingo is big (pink)) or predicate-noun (PN) constructions (e.g. A flamingo is a big (pink) bird), where the predicate noun was the immediate superordinate. Reaction times (RTs) and errors for relative sentences decreased when the superordinate was specified, but remained constant for absolute sentences. These data also suggest that the truth value of relative sentences depends, not just on the superordinate, but also on a more global standard for everyday, human-oriented objects. Experiment 2 extends these results in showing that ratings of the truth of relative sentences are a function of the difference in size between an instance and its superordinate standard (e.g., between the size of a flamingo and that of an average bird) and the difference between the instance and the standard for everyday objects. Experiment 3 replicated these findings using reaction time as the dependent measure.
