Partial information or facilitation? Different interpretations of results from speed-accuracy decomposition.

摘要: The speed-accuracy decomposition technique was developed by Meyer, Irwin, Osman, and Kounios (1988) to examine the time course of information processing. allows for estimation accuracy guesses that are induced presentation a response signal on proportion trials. Estimated guessing has been found be above chance increase as increases, suggesting based partial accumulated prior decision (sophisticated guesses). In this paper, different interpretation these data is presented. Results suggest signals may enhance speed regular processes, thereby violating temporal-independence assumption underlies technique. As shown Monte Carlo simulations, such facilitating effects can explain results from at least in part possibly full, even when actually (pure pure-guess model supported an experiment designed test between alternative interpretations. These point need great caution attempt infer processing accuracies estimated
