Dear all,
Timothy Dunn (PhD Candidate, University of Waterloo) will be speaking in our Cognitive Area Seminar this Friday, March 17th, 3:30 - 5 PM (Room S3/4, Stewart Biology Building, 1205 Docteur Penfield Avenue).
His talk is titled:
*"Determinants of effort: Error-likelihood strongly biases initial evaluations of effort."*

*Determinants of effort: Error-likelihood strongly biases initial evaluations of effort*
Timothy Dunn, Department of Psychology, University of Waterloo
Why are some actions evaluated as being effortful? We addressed this question by examining perceptions of effort when faced with a direct trade-off between how much time a task takes versus how error-prone it is. That is, do people prefer to engage in a task associated with low time demands but high error-likelihood, or a task associated with high time demands but low error-likelihood? We find that individuals perceive options that are high in error-likelihood and faster as more effortful than options that are low in error-likelihood and slower. Furthermore, when asked to evaluate which of two tasks was (a) more effortful, (b) more error-prone, and (c) more time consuming, effort-based and error-based choices closely tracked, though a similar association was not present for time-based choices. Last, the finding that high error-likelihood is closely tied to effort decisions was additionally demonstrated in free-choice contexts where experience with engaging in each of the tasks was afforded. Thus, in contrast to time-based accounts of effort, results are consistent with the likelihood of error commission driving effort-based choices. An *effort-as-errors *bias where individuals heuristically weigh the perceived likelihood of error commission will be proposed to account for the current results.
