Personal use of work computers: distraction versus destruction.

To explore definitions, frequencies, and motivation for personal use of work computers, we analyzed 329 employees' responses to an online survey, which asked participants to self-report frequencies for 41 computer behaviors at work. This sample (65% female, 74% European ethnicity, mean age of 36 years) was formed by soliciting participants through Internet Usenet groups, emails, and listservs. Results support a distinction between computer use that is counterproductive and that which is merely not productive. Nonproductive Computer Use occurred more when employees were younger (r = -0.31, p < 0.01), had Internet access at work longer (r = +0.16, p < 0.01), and had faster Internet connections at work than at home (r = +0.14, p < 0.01). Counterproductive Computer Use occurred more when Internet access was newer (r = -0.16, p < 0.01) and employees knew others who had been warned about misuse (r = +0.11, p < 0.05). While most employees who engaged in computer counterproductivity also engaged in computer nonproductivity, the inverse was uncommon, suggesting the need to distinguish between the two when establishing computer policies and Internet accessibility.     

Meeting the need or falling in line? The effect of laissez-faire formal leaders on informal leadership

We consider the utility of two contrasting theoretical perspectives in explaining how laissez-faire formal leaders and team member motivation to lead (MTL) influences informal leadership and team task performance. The first perspective, functional leadership theory, is the dominant lens used currently to understand informal leadership. However, we suggest that social learning theory offers a compelling alternative account. In a multiwave survey study of 344 members of 72 work teams, we find support for the social learning theory predictions that laissez-faire formal leaders are perceived by team members to engage in less modeling of effective leadership and as a result are negatively associated with informal leadership and team task performance. We do not find support for the functional leadership theory predictions that laissez-faire formal leaders are positively associated with team members’ informal leadership and team task performance, which would be due to an increased perceived need for leadership. The social learning effects are stronger for teams that are lower in member MTL and weaker for teams that are higher in member MTL. These results suggest social learning theory may be preferable to functional leadership theory for understanding informal leadership in teams.     

Discrepancy Between Self‐Report and School‐Record Grade Point Average: Correlates With Psychosocial Outcomes Among African American Adolescents1

The purpose of this study is to better understand the implications for using self‐reported grade point average (GPA) versus school‐record GPA in academic achievement research. First, we found that nearly half the youths interviewed overreported their GPAs by at least 2 half grades. Second, youth who overreported their GPAs also reported less psychological distress, more successful academic beliefs, and fewer problem behaviors. Third, we found that self‐reported GPA was associated with all 3 sets of variables, but school‐record GPA was associated with only problem behaviors. The findings suggest that it may be useful for researchers to consider how different measures of GPA may influence their results.     

Are average and symmetric faces attractive to infants? Discrimination and looking preferences

Young infants prefer to look at faces that adults find attractive, suggesting a biological basis for some face preferences. However, the basis for infant preferences is not known. Adults find average and symmetric faces attractive. We examined whether 5-8-month-old infants discriminate between different levels of averageness and symmetry in faces, and whether they prefer to look at faces with higher levels of these traits. Each infant saw 24 pairs of female faces. Each pair consisted of two versions of the same face differing either in averageness (12 pairs) or symmetry (12 pairs). Data from the mothers confirmed that adults preferred the more average and more symmetric versions in each pair. The infants were sensitive to differences in both averageness and symmetry, but showed no looking preference for the more average or more symmetric versions. On the contrary, longest looks were significantly longer for the less average versions, and both longest looks and first looks were marginally longer for the less symmetric versions. Mean looking times were also longer for the less average and less symmetric versions, but those differences were not significant. We suggest that the infant looking behaviour may reflect a novelty preference rather than an aesthetic preference.     

Remembrance of futures past

Much behavioural and physiological evidence suggests that the hippocampus encodes space. Puzzlingly, however, hippocampal damage also disrupts episodic memory. A recent study shows how these two faculties might be related, finding that the spatial firing of hippocampal 'place cells' is sometimes modulated by what the animal has recently done or what it will do next. Thus, the cells encode something resembling a context, or episode, collectively forming a potential substrate for episodic memory.     

Repetition priming mediated by task similarity in semantic classification

In the present study, the specificity of repetition priming between semantic classification tasks was examined using Osgood's (Osgood, Suci, & Tannenbaum, 1957) semantic space as a heuristic for determining the similarity between classifications. The classification tasks involved judging the meaning of words on semantic scales, such as pleasant/unpleasant. The amount of priming across classifications was hypothesized to decrease with increasing distance (decreasing similarity) between semantic scales in connotative semantic space. The results showed maximum repetition priming when the study and the test classifications were the same, intermediate degrees of priming when the study and the test classification scales shared loadings on semantic factors, and little priming when the study and the test classification scales loaded primarily on orthogonal semantic factors--that is, when the distance between scales was maximized. Consistent with the transfer-appropriate processing framework, repetition priming in semantic classifications was highly task specific, decreasing with increasing distance between classification scales.     

Racial Identity, Parental Support, and Alcohol Use in a Sample of Academically At-Risk African American High School Students

This study examined racial identity and parental support as predictors of alcohol use in a sample of 488 African American adolescents. Two dimensions of racial identity were investigated: (1) racial centrality (i.e., the significance that one places on race in defining oneself) and (2) private regard (i.e., the extent to which one feels positively about Black people). In addition, perceived support from mothers and fathers was examined. Multivariate results showed that private regard and father support were associated with less self-reported alcohol use after partialling out the effects of age and gender. An interaction between the two racial identity dimensions was also found such that private regard was associated with less alcohol use for adolescents who reported that race was a more central part of their identity.     

Response Time Based Nonparametric Kullback-Leibler Divergence Measure for Detecting Aberrant Test-Taking Behavior

Many important high-stakes decisions—college admission, academic performance evaluation, and even job promotion—depend on accurate and reliable scores from valid large-scale assessments. However, examinees sometimes cheat by copying answers from other test-takers or practicing with test items ahead of time, which can undermine the effectiveness of such assessments in yielding accurate, precise information of examinees' performances. This study focuses on the utility of a new nonparametric person-fit index using examinees' response times to detect two types of cheating behaviors. The feasibility of this method was investigated vis-à-vis a Monte Carlo simulation as well as through analyzing data from a large-scale assessment. Findings indicate that the proposed index was quite successful in detecting pre-knowledge cheating and extreme one-item cheating.     

Too Close for Comfort? Investigating the Nature and Functioning of Work and Non-work Role Segmentation Preferences

Purpose

We examine the bi-directional nature of role segmentation preferences—preferences to protect the home domain from work intrusions, and to protect the work domain from home intrusions—and hypothesize that the dimensions independently prompt individuals to manage their boundaries in ways that complement their preferences.

Design and Methodological Approach

In a series of three studies, we investigate whether segmentation preferences vary on two dimensions, how they reflect enactive and proactive boundary management, and their association with domain-specific satisfaction and performance.

Findings

In Study 1 (field design, n = 314), we confirmed that segmentation preferences comprise two distinct dimensions, and individuals experience fewer intrusions into the domain they desired to protect. In Study 2 (experimental design, n = 1253), we found that participants who prefer to protect their home domain are less inclined to accept jobs in scenarios where their significant other is employed in the same organization, and participants who prefer to protect their work domain are less inclined to initiate a romantic relationship in scenarios that involve a coworker. In Study 3 (field design, n = 65), we found that individuals who prefer to protect their work or home domain report greater satisfaction with the preferred domain, and whereas the preference to protect the work domain is not associated with higher supervisor ratings of job performance, preference to protect the home domain is associated with higher significant-other ratings of non-work performance.

Implications

Understanding employees’ proclivities to blur boundaries can inform recruitment and selection of employees to anticipate organizational fit, diagnose sources of misfit, structure individualized policies to ameliorate employee strain, and decrease turnover costs.

Originality/Value

This synthesis provides a unique investigation of segmentation preference dimensions’ differential functioning and reinforces the validity of the role segmentation preferences concept.

     

Chronic stress and sex differences on the recall of fear conditioning and extinction

Chronic stress effects and sex differences were examined on conditioned fear extinction. Male and female Sprague–Dawley rats were chronically stressed by restraint (6 h/d/21 d), conditioned to tone and footshock, followed by extinction after 1 h and 24 h delays. Chronic stress impaired the recall of fear extinction in males, as evidenced by high freezing to tone after the 24 h delay despite exposure to the previous 1 h delay extinction trials, and this effect was not due to ceiling effects from overtraining during conditioning. In contrast, chronic stress attenuated the recall of fear conditioning acquisition in females, regardless of exposure to the 1 h extinction exposure. Since freezing to tone was reinstated following unsignalled footshocks, the deficit in the stressed rats reflected impaired recall rather than impaired consolidation. Sex differences in fear conditioning and extinction were observed in nonstressed controls as well, with control females resisting extinction to tone. Analysis of contextual freezing showed that all groups (control, stress, male, female) increased freezing immediately after the first tone extinction trial, demonstrating contextual discrimination. These findings show that chronic stress and sex interact to influence fear conditioning, with chronic stress impairing the recall of delayed fear extinction in males to implicate the medial prefrontal cortex, disrupting the recall of the fear conditioning acquisition in females to implicate the amygdala, and nonstressed controls exhibiting sex differences in fear conditioning and extinction, which may involve the amygdala and/or corticosterone levels.
