The slope of the z-transformed receiver-operating characteristic (zROC) in recognition memory experiments is usually less than 1, which has long been interpreted to mean that the variance of the target distribution is greater than the variance of the lure distribution. The greater variance of the target distribution could arise because the…

The sources of forgetting in working memory (WM) are a matter of intense debate: Is there a time-related decay of memory traces, or is forgetting uniquely due to representation-based interference? In a previous study, we claimed to have provided evidence supporting the temporal decay hypothesis (S. Portrat, P. Barrouillet, & V. Camos, 2008).…

E. Brandstatter, G. Gigerenzer, and R. Hertwig (2006) contended that their priority heuristic, a type of lexicographic semiorder model, is more accurate than cumulative prospect theory (CPT) or transfer of attention exchange (TAX) models in describing risky decisions. However, there are 4 problems with their argument. First, their heuristic is not…

Rebuts the claims of Trusheim and Crouse, made in an earlier issue, that Scholastic Aptitude Test scores are no more effective predictors of college success than is high school class rank. Discusses inaccuracies in the data used by Trusheim and Crouse and points out errors in their analyses. (PGD)

Providing researchers, especially those in the social sciences, with access to publicly collected microdata furthers research while advancing public policy goals in a democratic society. However, while technological improvements have eased remote access to these databases and enabled computer using researchers to perform sophisticated statistical…

This paper describes the current status of teacher supply and demand in both special and general education, presents examples of the kinds of data and analyses which comply with the Individuals with Disabilities Education Act, and discusses how educational policymaking might be affected by the mandate to project future personnel needs.
