A latent variable modeling-based procedure is discussed that permits to readily point and interval estimate the design effect index in multilevel settings using widely circulated software. The method provides useful information about the relationship of important parameter standard errors when accounting for clustering effects relative to…

A focal goal of development science in recent years has been to document and understand the psychological processes that underlie inequality toward the goal of promoting equity and justice (e.g., Killen, Rutland, & Yip, 2016). This timely special section on economic inequality broadens the empirical conversation, which has centered mostly on…

Psychological and behavioral variance can be explained by differences in the environment, and between and within individuals. Almost 60 years ago, Cronbach (1957) called for converging investigations into all three sources as important for the development of accurate science and useful applications in the real world. Yet rifts among researchers…

Rouder, Morey, and Province (2013) stated that (a) the evidence-based case for psi in Storm, Tressoldi, and Di Risio's (2010) meta-analysis is supported only by a number of studies that used manual randomization, and (b) when these studies are excluded so that only investigations using automatic randomization are evaluated (and some additional…

Shultz and Wang (April 2011) drew attention to the ways in which understandings of retirement have changed over time, both in terms of the place of retirement in the lives of individuals and in terms of how retirement can no longer usefully be taken to comprise a single defining event.

Lindquist, Siegel, Quigley, and Barrett (2013) critiqued our recent meta-analysis that reported the effects of discrete emotions on outcomes, including cognition, judgment, physiology, behavior, and experience (Lench, Flores, & Bench, 2011).
