In unidimensional absolute identification tasks, participants identify stimuli that vary along a
single dimension. Performance is surprisingly poor compared with discrimination of the …

In the perceptual sciences, experimenters study the causal mechanisms of perceptual
systems by probing observers with carefully constructed stimuli. It has long been known …

When participants in psychophysical experiments are asked to estimate or identify stimuli
which differ on a single physical dimension, their judgments are influenced by the local …

Starting with a computational analysis of brightness matching, we develop a novel
variational framework able to model perceptual context-driven effects that may be extended …

We tested whether there is long-term learning in the absolute identification of line lengths.
Line lengths are unidimensional stimuli, and there is a common belief that learning of these …

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 …

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 …

We studied contrast and assimilation in three tasks: an exemplar-production task, a
categorization task, and a combined categorization-then-production task. On each trial of the …

In absolute identification experiments, the participant is asked to identify stimuli drawn from a
small set of items which differ on a single physical dimension (eg, 10 tones which vary in …

Relational Psychophysics in Humans and Animals offers a comprehensive and integrated
overview of the often fragmented field of psychophysics. It introduces key concepts in …
