Ergonomic Office Design and Aging: A Quasi-Experimental Field Study of Employee Reactions to an Ergonomics Intervention Program.

A naturally occurring quasi-experimental longitudinal field study of 87 municipal employees using pretest and posttest measures investigated the effects of an office workstation ergonomics intervention program on employees' perceptions of their workstation characteristics, levels of persistent pain, eyestrain, and workstation satisfaction. The study examined whether reactions differed between younger and older employees. Results revealed that workstation improvements were associated with enhanced perceptions of the workstation's ergonomic qualities, less upper back pain, and greater workstation satisfaction. Among those experiencing an improvement, the perceptions of workstation ergonomic qualities increased more for younger than older employees, supporting the "impressionable years" framework in the psychological literature on aging. Implications for human resources managers are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Affiliation with antisocial peers, susceptibility to peer influence, and antisocial behavior during the transition to adulthood.

Developmental theories suggest that affiliation with deviant peers and susceptibility to peer influence are important contributors to adolescent delinquency, but it is unclear how these variables impact antisocial behavior during the transition to adulthood, a period when most delinquent individuals decline in antisocial behavior. Using data from a longitudinal study of 1,354 antisocial youth, the present study examined how individual variation in exposure to deviant peers and resistance to peer influence affect antisocial behavior from middle adolescence into young adulthood (ages 14 to 22 years). Whereas we find evidence that antisocial individuals choose to affiliate with deviant peers, and that affiliating with deviant peers is associated with an individual’s own delinquency, these complementary processes of selection and socialization operate in different developmental periods. In middle adolescence, both selection and socialization serve to make peers similar in antisocial behavior, but from ages 16 to 20 years, only socialization appears to be important. After age 20, the impact of peers on antisocial behavior disappears as individuals become increasingly resistant to peer influence, suggesting that the process of desistance from antisocial behavior may be tied to normative changes in peer relations that occur as individuals mature socially and emotionally.

Effects of "voice" and peer opinions on responses to inequity.

Examined the effects of "voice" (participating in allocation decision making by expressing one's own opinion about the preferred allocation) on responses to an inequitable allocation. In addition to Ss' (82 female undergraduates) presence or absence of voice, Exp I manipulated (a) whether the allocation made by a "decision maker" (a confederate) was or was not made biased (due to self-interest) and (b) whether the S did or did not learn that a "co-worker" believed the allocation to be inequitable. Exp II, with 61 female high school students, manipulated presence/absence of voice and involved only a self-interested decision maker. In both experiments, the impact of voice was mediated by knowledge about the co-worker's opinion. When Ss had no knowledge about the co-worker's opinion (Exp I) or knew that the co-workers's opinion coincided with the decision maker's allocation (Exp II), there was evidence for a "fair process effect": Voice Ss expressed greater satisfaction than those with no voice.

Peer exclusion and victimization: Processes that mediate the relation between peer group rejection and children's classroom engagement and achievement?

Longitudinal data from a study of kindergarten through 5th graders were used to estimate a structural model in which chronic peer exclusion and chronic peer abuse were hypothesized to mediate the link between children's early peer rejection, later classroom engagement, and achievement. Peer exclusion and abuse were expected to predict changes in 2 forms of school engagement (classroom participation and school avoidance), and changes in both forms of engagement were expected to predict changes in achievement. The model fit the data well and lent support to the premise that distinct forms of peer maltreatment and classroom engagement mediate the link between early peer rejection and changes in children's achievement. Early peer rejection was associated with declining classroom participation and increasing school avoidance, but different forms of chronic peer maltreatment mediated these relations. Whereas chronic peer exclusion principally mediated the link between peer rejection and classroom participation, chronic peer abuse primarily mediated the link between rejection and school avoidance. Children's reduced classroom participation, more than gains in school avoidance, anteceded decrements in children's achievement. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Learning by reviewing.

Peer review of writing provides an alternative to the traditional approach of practicing writing with feedback from an instructor. Most of the limited research on peer review has examined the general effects or focused on the effects of receiving feedback from peers. The current study focused on the effects of giving feedback, that is, on whether students learn to write better by reviewing peer writing. Sixty-one undergraduate students were randomly assigned to reviewing, reading, or no-treatment control conditions. Reviewers rated and commented on papers written by peers. Readers read the same papers without commenting. All students then wrote a paper in the same genre but on a different topic. Students in the reviewing condition significantly outperformed those in both other conditions on the quality of the report. Follow-up analysis indicated that comments coded as “problem detection” and “solution suggestion” were positively correlated with writing outcomes for students in the reviewing condition. This research provides support for the use of peer review of writing as a learning activity. (PsycINFO Database Record (c) 2011 APA, all rights reserved)
