IMAGINATION'S GRIP ON SCIENCE

Abstract: In part because “imagination” is a slippery notion, its exact role in the production of scientific knowledge remains unclear. There is, however, one often explicit and deliberate use of imagination by scientists that can be (and has been) studied intensively by epistemologists and historians of science: thought experiments. The main goal of this article is to document the varieties of thought experimentation, not so much in terms of the different sciences in which they occur but rather in terms of the different functions they fulfil. I argue that thought experimentation (and hence imagination) plays a role not only in theory choice but in singular causal analysis and scientific discovery as well. I pinpoint, moreover, some of the rules governing the use of thought experiments in theory choice and in singular causal analysis, that is, some of the criteria they should meet in order to fulfil those functions successfully.     

Predicting conflict within romantic relationships during the transition to adulthood

We conducted a retrospective study between 1997 and 2000 with 200 participants in the Children in the Community Study at their mean age of 29 (range: 27–31 years). Participants completed detailed narrative interviews about their transition to adulthood and described monthly levels of partner conflict that had occurred between ages 17 and 27. Data from these interviews were used to investigate the developmental trajectory and predictors of conflict in romantic relationships. Multilevel growth models showed that partner conflict increased between ages 19 and 25 and then declined slightly. Parental divorce, low parental socioeconomic status, being an only child, being divorced, being married, cohabiting, and having biological offspring were associated with elevated partner conflict. Different patterns of association between these variables and partner conflict were observed in men and women.     

Interpersonal chemistry through negativity: Bonding by sharing negative attitudes about others

We propose that sharing a negative—as compared to a positive—attitude about a third party is particularly effective in promoting closeness between people. Findings from two survey studies and an experiment support this idea. In Studies 1 and 2, participants’ open‐ended responses revealed a tendency to recall sharing with their closest friends more negative than positive attitudes about other people. Study 3 established that discovering a shared negative attitude about a target person predicted liking for a stranger more strongly than discovering a shared positive attitude (but only when attitudes were weak). Presumably, sharing negative attitudes is alluring because it establishes in‐group/out‐group boundaries, boosts self‐esteem, and conveys highly diagnostic information about attitude holders. Despite the apparent ubiquity of this effect, participants seemed unaware of it. Instead, they asserted that sharing positive attitudes about others would be particularly effective in promoting closeness.     

EMPLOYEES' CHALLENGING JOB EXPERIENCES AND SUPERVISORS' EVALUATIONS OF PROMOTABILITY

Promotability evaluations are important for individuals' career development and organizations' human resource management practices. Nevertheless, little empirical research has addressed predictors of promotability evaluations, and the studies that have, have often focused on current job performance and fixed, nonbehavioral predictors. This study takes a more behavioral approach, and investigates whether besides how one performs (i.e., job performance) what one performs also serves as an indicator of promotability. Specifically, we examine the relationship between employees' challenging job experiences and supervisors' evaluations of employees' promotability over and above employees' current job performance. Results from 3 field studies, sampling different types of employees via different measures, consistently showed that challenging job experiences explained incremental variance in supervisory and organizational evaluations of promotability over and above current job performance and job tenure.     

Relational closeness: Comparing undergraduate college students' geographically close and long‐distance friendships

Abstract As interpersonal relationships change with the advent of new technology, researchers need to reexamine their theoretical constructs ( R. G. Adams, 1998 ). This study uses survey methodology to examine college undergraduates from the United States. It explores the concept of relational closeness by comparing how geographically close and long‐distance friends define closeness in their relationships. It assesses prior methods of defining and measuring closeness in interpersonal relationships for the impact of physical distance between the friends. Differences illustrate factors that are important in understanding relational closeness in general and in long‐distance relationships in particular.
