Leite, F. P. (2012). A Comparison of Two Diffusion-Process Models in Accounting for Payoff and Stimulus Frequency Manipulations. ATTention, Perception, & Psychophysics. doi: 10.3758/s13414-012-0321-0

From a reviewer: “This paper presents a nice detailed test of how payoff and stimulus frequency impact the decision process (assuming the decision process is a sequential sampling process).”


Leite, F. P. & Ratcliff, R. (2011). What Cognitive Processes Drive Response Biases? A Diffusion Model Analysis. Judgment and Decision MakinG, 6(7), 651-687. (Open access.)

From a reviewer: this paper makes “a potentially important and novel contribution” by studying which parameters of the Diffusion Model account for the behavioral changes associated with changes in stimulus frequency, relative payoffs, and decision threshold.


Leite, F. P. (2011). Larger reward values alone are not enough to entice more cooperation. THINking & Reasoning, 17, 82-103. doi: 10.1080/13546783.2010.537521

From a reviewer: This “manuscript elegantly demonstrates that increased cooperation for numeric (but not monetary) reward increases is not ubiquitous and that the prevalence of cooperative behavior depends on the strategies against which the participants play.”

From reviewers: This “paper takes up an ambitious and worthy task in attempting to extend the already extensive work that had been accomplished thus far with diffusion models ... to data from a multiple choice task. It also explores a variety of other model types ... and allows a direct comparison between several classes of models.”

 

Leite, F. P. (2009). Should IQ, perceptual speed, or both be used to explain response time? AMErican Journal of Psychology, 122, 517-526.

From a reviewer: “This is an interesting paper that attempts to better understand the relationship between perceptual speed and IQ by investigating how they relate to aspects of reaction time, namely the quality of evidence extracted from stimuli and degree of caution in decision making.”

From a reviewer: “This is a very nice little paper.  it makes a worthwhile statement on the relation between individual data and group data...”
