The dynamics of scaling: a memory-based anchor model of category rating and absolute identification.
A memory-based scaling model--ANCHOR--is proposed and tested. The perceived magnitude of the target stimulus is compared with a set of anchors in memory. Anchor selection is probabilistic and sensitive to similarity, base-level strength, and recency. The winning anchor provides a reference point near the target and thereby converts the global scaling problem into a local comparison. An explicit...
متن کاملMultidimensional Scaling Methods for Absolute Identification Data
Absolute identification exposes a fundamental limit in human information processing. Recent studies have shown that this limit might be extended if participants are given sufficient opportunity to practice. An alternative explanation is that the stimuli used – which vary on only one physical dimension – may elicit psychological representations that vary on two (or more) dimensions. Participants...
متن کاملPervasiveness and magnitude of context effects: evidence for the relativity of absolute magnitude estimation.
To test the assertion that absolute magnitude estimation serves to minimize context effects, two experiments were conducted in which area stimuli were judged under differing conditions. In Experiment 1, four groups of subjects made magnitude estimations of triangles ranging in area from 1.5 to 3,072 cm2. No standard or modulus was used, and instructions were similar to those used in absolute ma...
متن کاملPitch of Pure Tones Measured by Absolute Magnitude Estimation
Pitch of pure tones was measured by absolute magnitude estimation. Results show that the function relating pitch to frequency in log-log coordinates is much steeper below about 250 Hz than at higher frequencies. me results also show that in part of the scale pitch is proportional to the cochlear frequency coordinates. INTRODUCTION The psychological scale of pitch was investigated by a number of...
متن کاملMemory of relative magnitude judgments informs absolute identification
The question of whether people store absolute magnitude information or relative local comparisons of magnitudes has remained unanswered despite persistent efforts over the last three decades to resolve it. Absolute identification is one of the most rigorous experimental benchmarks for evaluating theories of magnitude representation. We characterize difficulties with both absolute and relative a...
