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.     

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.     

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.     

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.     

Dissociating perceptual and conceptual implicit memory in multiple sclerosis patients

Previous studies indicate that Multiple Sclerosis (MS) patients exhibit deficits in tests of explicit memory such as free recall, but show normal priming on implicit tests of memory such as word stem completion. However, the memory performance of patients with different MS disease subtypes has not been fully examined. In the current study, memory was assessed in Primary Progressive (PPMS), Relapsing Remitting (RRMS), and Secondary Progressive (SPMS) MS subgroups. Explicit memory as well as perceptual and conceptual implicit memory were examined using free recall, word fragment completion, and exemplar generation tests, respectively. All three groups of MS patients exhibited free recall deficits and normal priming on the exemplar generation test. However, the PPMS group exhibited a deficit in word fragment completion priming, whereas the RRMS and SPMS groups exhibited normal levels of priming on this task. Lesion load was assessed using magnetic resonance imaging and was negatively correlated with explicit memory performance, but it did not account for the observed deficits in perceptual implicit memory. The results indicate that PPMS patients exhibit a pattern of memory impairment that is distinct from that of the RRMS and SPMS groups. Moreover, the results indicate that perceptual implicit memory can be neurologically dissociated from conceptual implicit memory.     

Overhearing a language during childhood

Despite its significance for understanding of language acquisition, the role of childhood language experience has been examined only in linguistic deprivation studies focusing on what cannot be learned readily beyond childhood. This study focused instead on long-term effects of what can be learned best during childhood. Our findings revealed that adults learning a language speak with a more nativelike accent if they overheard the language regularly during childhood than if they did not. These findings have important implications for understanding of language-learning mechanisms and heritage-language acquisition.     

Holding on to childhood language memory

While early language experience seems crucial for mastering phonology, it remains unclear whether there are lasting benefits of speaking a language regularly during childhood if the quantity and quality of speaking drop dramatically after childhood. This study explored the accessibility of early childhood language memory. Specifically, it compared perception and production of Korean speech sounds by childhood speakers who had spoken Korean regularly for a few years during childhood to those of two other groups: (1) childhood hearers who had heard Korean regularly during childhood but had spoken Korean minimally, if at all; and (2) novice learners. All three groups were enrolled in first-year college Korean language classes. Childhood speakers were also compared to native speakers of Korean to see how native-like they were. The results revealed measurable long-term benefits of childhood speaking experience, underscoring the importance of early language experience, even if such experience diminishes dramatically beyond childhood.
