Social facilitation, the performance hindering or enhancing phenomenon that occurs when an individual completes a task under evaluation of an audience, is one of social psycholog y’s oldest and most fascinating phenomena (Aronson 2010). Sixty-two students at California State University, Sacramento completed a Color Categorization task alone or in the presence of an audience in order to examine ...

When testing that a sample of n points in the unit hypercube [0, 1] comes from a uniform distribution, the Kolmogorov–Smirnov and the Cramér–von Mises statistics are simple and well-known procedures. To encompass these measures of uniformity, Hickernell introduced the so-called generalized Lp-discrepancies. These discrepancies can be used in numerical integration through Monte Carlo and quasi–M...

The current paper describes a repertory grid approach for measuring trait-based self-discrepancies. This novel method is strictly empirical and more parsimonious than extant methods for assessing self-discrepancies on personality dimensions. We demonstrated this approach by measuring discrepancies between the actual, ideal, and ought selves on the Big Five personality traits and then assessing ...

OBJECTIVE To investigate whether discrepancies in trials of use of bone marrow stem cells in patients with heart disease account for the variation in reported effect size in improvement of left ventricular function. DESIGN Identification and counting of factual discrepancies in trial reports, and sample size weighted regression against therapeutic effect size. Meta-analysis of trials that pro...

Self-Discrepancy Theory (SDT) proposes that ideal-self discrepancies predict dejection/depression and ought-self discrepancies predict agitation/anxiety, but individual differences research has rarely found clear support for this pattern. After considering methodological and statistical reasons for these mixed findings, the present research tested SDT’s predictions using a multivariate structur...
