Me or we? The role of personality and justice as other-centered antecedents to innovative citizenship behaviors within organizations

The present research takes an "other-centered" approach to examining personal and contextual antecedents of taking charge behavior in organizations. Largely consistent with the authors' hypotheses, regression analyses involving data collected from 2 diverse samples containing both coworkers and supervisors demonstrated that the other-centered trait, duty, was positively related to taking charge, whereas the self-centered trait, achievement striving, was negatively related to taking charge. In addition, the authors found that procedural justice at the organizational level was positively related to taking charge when evaluated by a coworker, while both procedural and distributive justice were positively related to taking charge when considered by a supervisor. Theoretical and practical implications are discussed.     

Cognitive profiles of Japanese and Canadian kindergarten and first-grade children.

Japanese kindergarten and first-grade children were given the Canadian Cognitive Abilities Test (CCAT), with slight cultural modifications. Widely used in Canadian and American schools, the CCAT consists of three batteries: verbal, quantitative, and nonverbal. The sample consisted of 454 Japanese children (234 boys, 220 girls). Results were examined by 3-month age intervals (chronological age range, 60 to 87 months of age). Subjects' scores were compared with CCAT norms, based on the performance of 3,500 Canadian children at each age level. On each battery, the Japanese children outperformed their Canadian counterparts, but the differential was most apparent on the verbal battery. Moreover, on the nonverbal battery for kindergarten Japanese children (ages 60 to 72 months), significant differences appeared only with the 60- to 63-month age cohort. Results indicate that the higher achievement of Japanese children was apparent by the time they entered kindergarten and that higher Japanese educational productivity could not be solely attributed to schooling effects. Furthermore, the data indicate that the early academic advantage of Japanese children may widen as they progress through their first year of school. (Longitudinal replication studies are suggested for examination of the long-range impact of the early cognitive advantage of Japanese children.)     

The effect of eccentricity and the adapting level on the café wall illusion

The café wall pattern is composed of rows of alternating light and dark tiles, and alternate rows are shifted by one fourth of a cycle. The rows of tiles are separated by narrow horizontal mortar lines whose luminance is between those of the dark and the light tiles. Although the mortar lines are physically parallel, they are perceived to be tilted, which is known as the café wall illusion. In this study, an energy-based model for encoding orientation is implemented in order to estimate the strength of the café wall illusion, and it is shown that the estimated orientation depends on the spatial frequency to which each orientation-encoding unit is tuned. The estimation of mortar line orientation from an orientation-encoding unit tuned to a lower spatial frequency was greater than that from a unit tuned to a higher spatial frequency. It is assumed that the perceived mortar line orientation is the result of an integration of responses from the orientation-encoding units tuned to various spatial frequencies. This leads to the prediction that under viewing conditions in which responses from orientation-encoding units tuned to a higher spatial frequency are presumably weakened, the strength of the café wall illusion increases. In agreement with this prediction, it is shown that the café wall illusion is stronger when the café wall image is presented at the periphery or is observed under low luminance levels. On the other hand, the weighted averaging of the estimated mortar orientations across spatial frequencies overestimates the perceived orientation of the mortar lines. This suggests that the final percept of the café wall illusion could be determined by some kind of nonlinear interaction, such as an inhibitory interaction, between orientation-encoding units.     

Changes in somatosensory evoked potentials and Hoffmann reflexes during fast isometric contraction of foot plantarflexor in humans

In the present study, the extent to which the early component of somatosensory evoked potentials (SEPs) and the Hoffmann (H-) reflex induced by stimulation of the posterior tibial nerve are altered during the ascending and descending phases of fast plantarflexion was investigated. SEPSs and H-reflex of the soleus following tibial nerve stimulation were examined during fast plantarfiexion when performed by nine normal subjects. The analyses focused on differences in amplitude modulation of the P30-P40 component of SEP and the H-reflex between the ascending and descending phases of full-wave rectified and averaged soleus electromyographic (EMG) activity. The H-reflex amplitude was significantly increased and decreased during the ascending and descending phases more than under resting control conditions, respectively. The reduction of SEP amplitude was 49% for the ascending phase and 83% for the descending phases with respect to the resting situation. Modulation of SEP during the ascending and descending phases was robustly retained even during ischemic nerve blockade of large diameter afferent fibers. These findings suggest that the transmission of afferent inputs from muscle spindles to motoneurons and to the somatosensory cortex during fast isometric contraction of the plantar flexor is regulated in a time-dependent fashion by descending commands.     

Age of first onset major depression in Chinese Americans

Using data from the Chinese American Epidemiological Study, risk for experiencing an initial episode of major depression across the life course was examined. Data were collected on 1,747 U.S.-born and foreign-born Chinese Americans (ages 18-65 years). Results suggest that Chinese American women did not evidence higher risk than Chinese American men for experiencing a 1st major depressive episode. Risk for experiencing a 1st depressive episode decreased as length of residence in the United States increased. Although those who immigrated at younger ages evidenced greater overall risk, those who came at later ages were more likely to become depressed at or soon after arrival. Competing theories of acculturation-related risk are discussed and directions for future research are proposed.     

Employee self-enhancement motives and job performance behaviors: investigating the moderating effects of employee role ambiguity and managerial perceptions of employee commitment

This study examined the effects of employee self-enhancement motives on job performance behaviors (organizational citizenship behaviors and task performance) and the value of these behaviors to them. The authors propose that employees display job performance behaviors in part to enhance their self-image, especially when their role is not clearly defined. They further argue that the effects of these behaviors on managerial reward recommendation decisions should be stronger when managers believe the employees to be more committed. The results from a sample of 84 working students indicate that role ambiguity moderated the effects of self-enhancement motives on job performance behaviors and that managerial perceptions of an employee's commitment moderated the effects of those organizational citizenship behaviors that are aimed at other individuals on managers' reward allocation decisions.     

The Global Context and People at Work: Special Issue Introduction

Although considerable research has been conducted on a variety of cross‐cultural management topics, we still know very little about how organizations can effectively manage people involved in global work or how cross‐cultural differences impact individuals and groups at work. To address this gap, we edited a special issue of Personnel Psychology that presents scholarly research contributing to understanding how global experiences and contexts impact people at work. We identified 3 research themes: cross‐cultural comparisons, the different types of global workers, and theoretical perspectives that underlie the accepted articles’ contributions to this special issue. We conclude with specific theoretical and methodological recommendations for research on human resource management and organizational behavior topics incorporating the global context.     

Decision-making deficit of a patient with axonal damage after traumatic brain injury

Patients with traumatic brain injury (TBI) were reported to have difficulty making advantageous decisions, but the underlying deficits of the network of brain areas involved in this process were not directly examined. We report a patient with TBI who demonstrated problematic behavior in situations of risk and complexity after cerebral injury from a traffic accident. The Iowa gambling task (IGT) was used to reveal his deficits in the decision-making process. To examine underlying deficits of the network of brain areas, we examined T1-weighted structural MRI, diffusion tensor imaging (DTI) and Tc-ECD SPECT in this patient. The patient showed abnormality in IGT. DTI-MRI results showed a significant decrease in fractional anisotropy (FA) in the fasciculus between the brain stem and cortical regions via the thalamus. He showed significant decrease in gray matter volumes in the bilateral insular cortex, hypothalamus, and posterior cingulate cortex, possibly reflecting Wallerian degeneration secondary to the fasciculus abnormalities. SPECT showed significant blood flow decrease in the broad cortical areas including the ventromedial prefrontal cortex (VM). Our study showed that the patient had dysfunctional decision-making process. Microstructural abnormality in the fasciculus, likely from the traffic accident, caused reduced afferent feedback to the brain, resulting in less efficient decision-making. Our findings support the somatic-marker hypothesis (SMH), where somatic feedback to the brain influences the decision-making process.     

Social influence of a coworker: A test of the effect of employee and coworker exchange ideologies on employees’ exchange qualities

Integrating social comparison and social influence perspective within a social exchange theoretical framework, we examine how the exchange ideologies of employees and their coworkers affect the quality of the employees’ social exchanges. Drawing from social exchange theory, we hypothesize that the exchange ideology of a focal employee has a negative relationship with the quality of his/her social exchange with the organization (i.e., felt obligation) and the quality of his/her social exchange with a leader (i.e., leader–member exchange), both of which are related to task performance. Furthermore, we propose that a coworker close to the employee acts as a social referent and provides cues to exert influence on these relationships. Using data collected from 374 (employee–coworker–manager) triads in Hong Kong, we find support for the aforementioned relationships as well as the moderating roles of a coworker’s exchange ideology.
