Higher order sequential effects in psychophysical judgments.
We found that the depth of sequential effects depends on the judgment task. An experiment with squares indicated that stimulus-response pairs up to two trials back were included in the judgment process when subjects were required to make category judgments of size, whereas only the immediately preceding event was incorporated when subjects were making magnitude estimations. In the case of categ...
متن کاملDepth of Sequential Dependencies in Psychophysical Judgment
In a first experiment, subjects had to rate the size of squares. We found that the depth of sequential dependencies depended on the judgment task. Whereas for magnitude estimation only the immediately preceding stimulus-response event was included in the judgment process, events up to two trials back were incorporated for category judgment. In a second experiment, squares of two categories diff...
متن کاملDecontaminating Human Judgments By Removing Sequential Dependencies
For over half a century, psychologists have been struck by how poor people are at expressing their internal sensations, impressions, and evaluations via rating scales. When individuals make judgments, they are incapable of using an absolute rating scale, and instead rely on reference points from recent experience. This relativity of judgment limits the usefulness of responses provided by indivi...
متن کاملSequential phenomena in psychophysical judgments: A theoretical analysis
This paper deals with an analysis of psychophysical detection experiments designed to assess the limit of a human observer's level of sensitivity. A mathematical theory of the detection process is introduced that, in contrast to previous theories, provides an analysis of the sequential effects observed in psychophysical data. Two variations of the detection task are considered: information feed...
متن کاملA model of positive sequential dependencies in judgments of frequency
Positive sequential dependencies occur when the response on the current trial n is positively correlated with the response on trial n − 1. They are observed in a Judgment of Frequency (JOF) recognition memory task (Malmberg & Annis, 2012), and we developed a process model of them in the REM framework (Malmberg, Holden, & Shiffrin, 2004; Shiffrin & Steyvers, 1997) by assuming that features that ...
