The Multitasking Preference Inventory: Toward an Improved Measure of Individual Differences in Polychronicity

This article describes the initial development of a new measure of individual polychronicity, a construct indicating a preference for multitasking as opposed to performing only one task at a time. Following a brief review of past definitional issues, a revised definition is offered and a new measure of polychronicity—the Multitasking Preference Inventory (MPI)—is created based on this definition. Three studies describe the creation, pilot testing, and psychometric refinement of an initial pool of items (Study 1); a convergent and discriminant validity analysis (Study 2); and initial findings with respect to the criterion-related validity of scores on the MPI (Study 3). Together, these findings provide preliminary evidence for the reliability of scores on the MPI and the validity of the MPI in predicting variables relevant to multitasking.     

Forecasting “friends forever”: A longitudinal investigation of sustained closeness between best friends

Using data collected across 19 years, the chief goal of this study was to discover predictors of continued relational closeness between best friends. Participants were same‐sex and cross‐sex best friend pairs recruited from a small Midwestern college. In 1983, participants completed several tests and activities designed to assess facets of intimacy, with follow‐up studies in 1987 and 2002 measuring relational closeness. Regression analysis indicates that both manifest similarity and months of closeness in 1983 are associated with relational closeness in 2002. These results suggest that the investment of resources in the friendship and similarity between friends facilitate friendship longevity and that Kelley et al.’s (1983) conceptualization of closeness as related to interdependence is empirically robust.     

Detecting and Deterring Insufficient Effort Responding to Surveys

Purpose  

Responses provided by unmotivated survey participants in a careless, haphazard, or random fashion can threaten the quality of data in psychological and organizational research. The purpose of this study was to summarize existing approaches to detect insufficient effort responding (IER) to low-stakes surveys and to comprehensively evaluate these approaches.     

How the adoption of impression management goals alters impression formation

Five experiments (N = 390) tested the hypothesis that adopting an impression management goal leads the impression manager to view an interaction partner as having less of the trait he or she is attempting to express. This hypothesis was confirmed for the impression management goals of appearing introverted, extraverted, smart, confident, and happy. Experiment 2 shows that adoption of the impression goal could alter judgments even when participants could not act on the goal. Experiment 3 provides evidence that adopting an impression management goal prompted a comparison mind-set and that this comparison mind-set activation mediated target judgments. Experiment 4 rules out a potential alternative explanation and provides more direct evidence that comparison of the impression manager's self-concept mediates the impression of the target. Experiment 5 eliminates a potential confound and extends the effect to another impression goal. These experiments highlight the dynamic interplay between impression management and impression formation.     

Construct representation and definitions in psychopathology: the case of delusion

Background  

Delusion is one of the most intriguing psychopathological phenomena and its conceptualization remains the subject of genuine debate. Claims that it is ill-defined, however, are typically grounded on essentialist expectations that a given definition should capture the core of every instance acknowledged as delusion in the clinical setting.
