The Interaction Effects of Leader and Follower Conscientiousness on Person-Supervisor Fit Perceptions and Follower Outcomes: A Cross-Level Moderated Indirect Effects Model

ABSTRACT

The primary purpose of this study is to examine how the cross-level interaction between leader and follower conscientiousness influences person-supervisor (PS) fit perceptions, which in turn impact follower work attitudes and organizational citizenship behavior (OCB). Based on a sample of 1,204 participants in 167 work teams, the results of our cross-level moderated indirect effects model show that highly conscientiousness followers whose leaders also have high levels of conscientiousness experience enhanced perceptions of PS fit which result in higher levels of job satisfaction and OCB and lower levels of intention to quit. The study suggests that high leader conscientiousness serves as a supportive situational cue that motivates followers to more fully express their conscientiousness and act in ways consistent with their conscientiousness.     

Validity of observer ratings of the five-factor model of personality traits: a meta-analysis

Conclusions reached in previous research about the magnitude and nature of personality-performance linkages have been based almost exclusively on self-report measures of personality. The purpose of this study is to address this void in the literature by conducting a meta-analysis of the relationship between observer ratings of the five-factor model (FFM) personality traits and overall job performance. Our results show that the operational validities of FFM traits based on observer ratings are higher than those based on self-report ratings. In addition, the results show that when based on observer ratings, all FFM traits are significant predictors of overall performance. Further, observer ratings of FFM traits show meaningful incremental validity over self-reports of corresponding FFM traits in predicting overall performance, but the reverse is not true. We conclude that the validity of FFM traits in predicting overall performance is higher than previously believed, and our results underscore the importance of disentangling the validity of personality traits from the method of measurement of the traits.     

Multiple Roles of Married Korean Women: Effect on Depression

This study was designed to examine relationships between roles of employed married women in Seoul, South Korea, perceptions of their work role, coping patterns, and levels of depression. The convenience sample contained 382 women, aged 25–55 years, who were living with their husbands and working at least 20 hr weekly. Participants completed five questionnaires: demographic, Center for Epidemiological Studies—Depression Scale, Index of Sex-Role Orientation, Role Sharing, and Coping Strategies. Multiple regression analysis revealed several statistically significant relationships. Higher levels of depression were found in women who perceived motherhood and career roles as incompatible, those who coped by working harder, and those who spent less time helping children with homework. Women who owned their houses had lower levels of depression.     

Branded entertainment: Gender differences in reactions to star ratings

The consumer behavior literature shows that men are externally focused and women are internally focused consumers. The authors conduct three studies to test gender differences in the use of media‐posted public ratings for deciding whether to recommend branded entertainment films. The Study 1 results indicate that men are more (less) likely to recommend films that have high (low) star ratings, but women are equally likely to recommend films regardless of star ratings. In an interesting twist, Study 2 results show that if women are momentarily distracted by being made more aware of their surroundings, they process information similarly to men and are more persuaded by public ratings. In Study 3, the authors replicate and extend the findings by including a no‐star control group and examining additional variables—film and brand attitudes and recommendations—with a no star rating control group. The overall results show that men (women) are more (less) likely to look to public ratings for forming film and brand attitudes and recommendations.     

Effect of loudness on reaction time and response force in different motor tasks

Van der Molen and Keuss, in 1979 and 1981, showed that paradoxically long reaction times occur with extremely strong auditory stimuli when the task is difficult, e.g., choice-by-location or Simon paradigm. It was argued that this paradoxical behavior of RT is due to active inhibition of an arousal-dependent bypassing mechanism to prevent false responses. As the peak force, i.e., maximal force exerted by participants on a response key, is considered to be related to immediate arousal, we predicted that for extremely loud stimuli and for difficult tasks, lengthening of RT should be associated with reduction of peak force. Moreover, these effects should be enhanced when emphasis is on accuracy rather than speed. Although the relation between RT and intensity depended on task difficulty, no increase in RT was found for the loudest tones. Moreover, peak force increased monotonically with loudness, showing no tendency to be suppressed for loudest tones and difficult tasks.     

Sense of Community in Clubhouse Programs: Member and Staff Concepts

Psychological sense of community within psychosocial rehabilitation clubhouse programs was examined using concept mapping with 18 members and 18 staff from 10 programs. Members identified four concepts: Recovery, social connections, membership, and tasks and roles. Members described hope and healing as aspects of recovery. Members' views on sense of community focused on the rehabilitation and social nature of the program. Staff also identified four concepts: Affiliation and support for members, shared experiences, clubhouse organization, and task and roles. The staff concept of clubhouse organization, which incorporated the ideas of leadership and organization of physical space and the concept of task and roles, was based on ideas of shared responsibility and clubhouse procedures. Staffs' views on sense of community strongly reflected their formal training in clubhouse principles. The relation of these concepts to McMillan and Chavis' theoretical framework for sense of community is discussed and recommendations for practice provided. Sandra E. Herman is now an independent program evaluation consultant. Catherine Ferguson is now an independent consultant on psychosocial programs.     

Mechanisms underlying spatial coding in a multiple-item Simon task

Choice responses are faster when target position and response side correspond than when they do not, even if target position is response-irrelevant. This "Simon effect" has also been observed in case of multi-item arrays. Generally, it is assumed that an automatically generated spatial response code is responsible for the effect. The referential-coding account assumes that this code is directly related to the target, although the moment of production of the code is not fully clear. The attention-shift account assumes that the code is directly related to the direction of the most recent attentional shift. An experiment was performed in which left or right target locations were indicated by arrows occurring before (precue), simultaneous with (simcue), or after (postcue) six-element arrays. Overt responses and EEG potentials were recorded. The Simon effect was present in all conditions, and decreased when responses were slower. No relation was found between amplitude of posterior lateralized components and the magnitude of the Simon effect. A posterior contralateral negativity was also found after presenting the arrays in the precue condition, which might reflect the reorienting of attention toward the target position. The results are more favorable to the referential-coding account although this account becomes very similar to the attention-shift hypothesis as the moment of formation of the spatial response code is related to effective target onset rather than to stimulus onset.     

Galantamine facilitates acquisition of hippocampus-dependent trace eyeblink conditioning in aged rabbits

Cholinergic systems are critical to the neural mechanisms mediating learning. Reduced nicotinic cholinergic receptor (nAChR) binding is a hallmark of normal aging. These reductions are markedly more severe in some dementias, such as Alzheimer's disease. Pharmacological central nervous system therapies are a means to ameliorate the cognitive deficits associated with normal aging and aging-related dementias. Trace eyeblink conditioning (EBC), a hippocampus- and forebrain-dependent learning paradigm, is impaired in both aged rabbits and aged humans, attributable in part to cholinergic dysfunction. In the present study, we examined the effects of galantamine (3 mg/kg), a cholinesterase inhibitor and nAChR allosteric potentiating ligand, on the acquisition of trace EBC in aged (30–33 months) and young (2–3 months) female rabbits. Trace EBC involves the association of a conditioned stimulus (CS) with an unconditioned stimulus (US), separated by a stimulus-free trace interval. Repeated CS–US pairings results in the development of the conditioned eyeblink response (CR) prior to US onset. Aged rabbits receiving daily injections of galantamine (Aged/Gal) exhibited significant improvements compared with age-matched controls in trials to eight CRs in 10 trial block criterion (P = 0.0402) as well as performance across 20 d of training [F(1,21) = 5.114, P = 0.0345]. Mean onset and peak latency of CRs exhibited by Aged/Gal rabbits also differed significantly [F(1,21) = 6.120/6.582, P = 0.0220/0.0180, respectively] compared with age-matched controls, resembling more closely CR timing of young drug and control rabbits. Galantamine did not improve acquisition rates in young rabbits compared with age-matched controls. These data indicate that by enhancing nicotinic and muscarinic transmission, galantamine is effective in offsetting the learning deficits associated with decreased cholinergic transmission in the aging brain.
