Age and Time Horizons Are Associated With Preferences for Helping Colleagues

Abstract

Abstract The present study examined the causal role of time horizons in age differences in worker motivation. Based on socioemotional selectivity theory (SST), we hypothesized that under unspecified time horizons, older workers prefer to engage in emotionally meaningful work activities more so than younger workers. We further hypothesized that when time horizons at work are expanded or limited, age differences are eliminated. We recruited a sample of employees (N = 555) and randomly assigned them to one of three experimental conditions: a no-instruction condition in which time horizons were not specified, an expanded time horizons condition, or a limited horizons condition. We asked participants to choose from among three options for work-related activities: Helping a colleague or a friend, working on a career-advancing project, or working on a project which may take the company in a new direction. Consistent with SST postulates, we found that age was associated with preferences for helping colleagues in the unspecified horizons condition, and that age differences were eliminated when time horizons were extended or limited. As hypothesized, expanding time horizons reduced employees’ likelihood of choosing to help colleagues. Contrary to our hypothesis, limiting time horizons also reduced the likelihood of choosing to help colleagues. Alternative explanations are considered. Findings suggest that age differences in worker motivation are shaped by time horizons and that modification of time horizons can alter work preferences.
