Why to Treat Subjects as Fixed Effects
Peer reviewed Peer reviewed

Adelman, James S.; Estes, Zachary – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2015
Adelman, Marquis, Sabatos-DeVito, and Estes (2013) collected word naming latencies from 4 participants who read 2,820 words 50 times each. Their recommendation and practice was that R2 targets set for models should take into account subject idiosyncrasies as replicable patterns, equivalent to a subjects-as-fixed-effects assumption. In light of an…

Three Tests and Three Corrections: Comment on Koen and Yonelinas (2010)

Jang, Yoonhee; Mickes, Laura; Wixted, John T. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
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…

Dynamic Search and Working Memory in Social Recall
Peer reviewed Peer reviewed
Direct linkDirect link
Hills, Thomas T.; Pachur, Thorsten – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
What are the mechanisms underlying search in social memory (e.g., remembering the people one knows)? Do the search mechanisms involve dynamic local-to-global transitions similar to semantic search, and are these transitions governed by the general control of attention, associated with working memory span? To find out, we asked participants to…

Further Evidence for Temporal Decay in Working Memory: Reply to Lewandowsky and Oberauer (2009)
Peer reviewed Peer reviewed
Direct linkDirect link
Barrouillet, Pierre; Portrat, Sophie; Vergauwe, Evie; Diependaele, Kevin; Camos, Valerie – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2011
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).…

Recognition ROCS Are Curvilinear--Or Are They? On Premature Arguments against the Two-High-Threshold Model of Recognition
Peer reviewed Peer reviewed
Direct linkDirect link
Broder, Arndt; Schutz, Julia – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2009
Recent reviews of recognition receiver operating characteristics (ROCs) claim that their curvilinear shape rules out threshold models of recognition. However, the shape of ROCs based on confidence ratings is not diagnostic to refute threshold models, whereas ROCs based on experimental bias manipulations are. Also, fitting predicted frequencies to…

Nonmonotonic Extrapolation in Function Learning
Peer reviewed Peer reviewed
Direct linkDirect link
Bott, Lewis; Heit, Evan – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2004
This article reports the results of an experiment addressing extrapolation in function learning, in particular the issue of whether participants can extrapolate in a nonmonotonic manner. Existing models of function learning, including the extrapolation association model of function learning (EXAM; E. L. DeLosh, J. R. Busemeyer, & M. A. McDaniel,…
