Selection,optimization, and compensation strategies: Interactive effects on daily work engagement

The theory of selective optimization with compensation (SOC) proposes that the “orchestrated” use of three distinct action regulation strategies (selection, optimization, and compensation) leads to positive employee outcomes. Previous research examined overall scores and additive models (i.e., main effects) of SOC strategies instead of interaction models in which SOC strategies mutually enhance each other's effects. Thus, a central assumption of SOC theory remains untested. In addition, most research on SOC strategies has been cross-sectional, assuming that employees' use of SOC strategies is stable over time. We conducted a quantitative diary study across nine work days (N = 77; 514 daily entries) to investigate interactive effects of daily SOC strategies on daily work engagement. Results showed that optimization and compensation, but not selection, had positive main effects on work engagement. Moreover, a significant three-way interaction effect indicated that the relationship between selection and work engagement was positive only when both optimization and compensation were high, whereas the relationship was negative when optimization was low and compensation was high. We discuss implications for future research and practice regarding the use of SOC strategies at work.     

Proactivity,adaptability and boundaryless career attitudes: The mediating role of entrepreneurial alertness

We examined the role of entrepreneurialism in careers in the information society and global economy, bringing together key constructs in the fields of career studies and entrepreneurship. Specifically, our study involving a diverse group of 750 undergraduate students from Singapore showed that entrepreneurial alertness to opportunities partially mediates the relation of proactive personality to boundaryless career mindset and career adaptability, but not to self-directed or protean career attitudes. Findings are discussed in relation to the contribution of entrepreneurialism to careers research and the larger issues of workforce development.     

Cohen's d Corrected for Case IV Range Restriction: A More Accurate Procedure for Evaluating Subgroup Differences in Organizational Research

Organizational and staffing researchers are often interested in evaluating whether subgroup differences exist (e.g., between Caucasian and African‐American individuals) on predictors of job performance. To investigate subgroup differences, researchers often will collect data from current employees to make inferences about subgroup differences among job applicants. However, the magnitude of subgroup differences (i.e., Cohen's d) within incumbent samples may be different (i.e., smaller) than the magnitude of subgroup differences in applicant samples because selection of applicants typically reduces the variance of scores on the predictors (i.e., because lower scoring applicants are not selected). If researchers seek to generalize a d value in an incumbent sample to the applicant population, they may use Bobko, Roth, and Bobko's (correcting the effect size of d for range restriction and unreliability, 2001) Case II or III correction. By extension, Hunter, Schmidt, and Le (implications of direct and indirect range restriction for meta‐analysis methods and findings, 2006) have proposed a Case IV correction, which is more realistic than Bobko et al.'s approach. Therefore, this paper develops a Case IV correction for d (i.e., d_c4). The simulation results showed that the d_c4 was generally accurate across 6,000 simulation conditions. Moreover, 2 published datasets were reanalyzed to show the influence of the Case IV correction on d. In addition, implications and future directions of the d_c4 are discussed.     

The coupling of short sleep duration and high sleep need predicts riskier decision making

Abstract

Objective: To examine how risk-related decision making might be associated with habitual sleep variables, including sleep variability, sleep duration and perceived sleep need in young adults cross-sectionally and longitudinally.

Design: 166 participants completed a 7-day protocol with sleep and risk-related decision-making measures at baseline (T1) and 12 months later (T2).

Results: Habitual short sleep duration (averaging < 6?h nightly) was identified in 11.0% in our sample. After controlling for baseline demographic factors and risk-taking measures, self-reported sleep need at T1 interacted with habitual short sleep in predicting risk taking at follow-up (F_8,139=9.575, adjusted R²=.431, p<.001). T1 greater perceived sleep need predicted more risk taking among short sleepers, but decreased risk taking among normal sleepers at T2. Variable sleep timing was cross-sectionally correlated with making more Risky choices at baseline and fewer Safe choices after loss at follow up.

Conclusions: Young adults with variable sleep timing and those with short sleep duration coupled with high perceived sleep need were more likely to take risks. The moderating effects of perceived sleep need suggest that individual differences may alter the impact of sleep loss and hence should be measured and accounted for in future studies.     

Alexithymia and relaxation: Considerations in optimising the emotional effectiveness of journaling about stressful experiences

The emotional benefits of pairing a brief relaxation with journaling about a stressful event were considered through an experimental design, with alexithymia included as a potential moderator. Participants (n=217) were randomly assigned to a full treatment group (n=54), relaxation-only group (n=57), journaling-only group (n=51), or control group (n=55). The results indicated an interaction, with high-alexithymic participants in the full treatment group reporting increased levels of emotional distress several days after writing. The hypothesis that preceding journaling with a relaxation would be beneficial for non-alexithymic participants was not supported. These findings contribute to the ongoing examination of how best to optimise the effectiveness of journaling. They also lend support to the importance of including alexithymia as a moderator variable in future journaling research.     

Regulatory focus influences perseveration and distractibility in task switching

In two experiments, we investigated the effect of regulatory focus (Higgins, Am Psychol, 52, 1280–1300, 1997) on people’s maintenance and switching behavior. In the experimental tasks, participants were asked to react selectively to one category of stimuli while ignoring the other. After several practice trials, participants had to switch either to new stimuli which were paired with former target stimuli (i.e., in the perseveration condition), or switch to former distracter stimuli which were paired with new stimuli (i.e., in the learned irrelevance condition). Results from both experiments indicated that a promotion focus promoted switching to new stimuli in the perseveration condition, at the cost of poorer performance on switching to former distracters in the learned irrelevance condition. This pattern of results applied to both chronic individual differences in regulatory focus (Experiment 1), and regulatory focus temporarily manipulated in the laboratory (Experiment 2). It suggests that whereas a promotion focus indeed promotes cognitive flexibility, it also incurs a cost in terms of increased likelihood of being distracted.     

Simultaneous backward conditioned inhibition and mediated conditioning

Demonstrations of retrospective revaluation suggest that remembered stimuli undergo a reduction in association with the unconditioned stimulus (US) present during learning. Conversely, demonstrations of mediated conditioning in flavor-conditioning experiments with rats suggest that remembered stimuli undergo an increase in association with the US present during learning. In a food allergy prediction task with 23 undergraduates, we demonstrated simultaneous backward conditioned inhibition and mediated conditioning effects. These results are compatible with the hypothesis that the direction of change (decrease or increase) in associative strength depends on whether the remembered stimulus was of a different category (conditioned stimulus/antecedent) or the same category (US/outcome) as the presented US.

The impact of school-based mentoring on youths with different relational profiles

Associations between youths' relationship profiles and mentoring outcomes were explored in the context of a national, randomized study of 1,139 youths (54% female) in geographically diverse Big Brothers Big Sisters school-based mentoring programs. The sample included youths in Grades 4-9 from diverse racial and ethnic backgrounds, the majority of whom were receiving free or reduced-price lunch. Latent profile analysis, a person-oriented approach, was used to identify 3 distinct relational profiles. Mentoring was found to have differential effects depending on youths' preintervention approach to relationships. In particular, youths who, at baseline, had satisfactory, but not particularly strong, relationships benefited more from mentoring than did youths with profiles characterized by either strongly positive or negative relationships. Implications for research and practice are discussed.
