2018 1/f noise replication
Year: 2018
Type: preprint
Abstract: We manipulate motivation/effort in a long 400-trial weapon identification task (Payne, 2001), such that control participants "do their best", one group of experimental participants makes an effort to "avoid bias", and another group of experimental participants makes an effort to "focus on the object." One objective of this study is to estimate a pattern of serial dependency in reaction times, called 1/f noise. We have found that 1/f noise decreases when participants exert greater effort (particularly in the "avoid bias" condition), so we will compare the control condition to the "avoid bias" condition. A second objective is to estimate empirical ROC curves by computing average hit/false alarm rates for each object in the task. A third objective is to look at how the three goal conditions change in performance over time. Here, we predict that participants who practice focusing on the object will, over time, show reductions in bias relative to the "avoid bias" and control conditions.
