Depth 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 کاملAnalogs in Luce's global psychophysical theory of Stevens's psychophysical regression effect.
This article is based on the magnitude production representation in Luce's (2004, 2011) global psychophysical theories for subjective intensity of both binary and unary continua. It is shown that the slopes of certain predicted linear relationships for magnitude production and estimation differ when, in the two procedures, the respondent-generated reference signals differ. This contrasts with S...
متن کاملDepth Cues Changes Circle Size Judgment Measured by Psychophysical Scaling
The aim of our study was to investigate whether different circle sizes, in conditions of pure size judgment and in a simple contextual judgment with an interfering depth suggesting background, produce different size perceptions. We used the magnitude estimation to obtain the apparent size of circles under two different experimental conditions: with a neutral black background and with a converge...
متن کاملThe dud-alternative effect in likelihood judgment.
The judged likelihood of a focal outcome should generally decrease as the list of alternative possibilities increases. For example, the likelihood that a runner will win a race goes down when 2 new entries are added to the field. However, 6 experiments demonstrate that the presence of implausible alternatives (duds) often increases the judged likelihood of a focal outcome. This dud-alternative ...
متن کاملAssessments of Spatial Temporal Order Judgment (toj) Thresholds Using Different Psychophysical Methods
Spatial TOJ measures the ability to correctly perceive the order of two tones presented to the two ears. This task has been used in both basic and applied research, testing different populations, such as dyslexic readers, aphasic patients, aging adults, and sleep deprived adults. A variety of methodologies similar to Fechner’s original methods have been used, resulting in a wide range of report...
