Schematic of stimuli and task for the current experiment. Molly J. Henry J.

The time-change (i.e., duration-judgment) task is shown on the top line, and the pitch-change task is shown on the bottom line. On each trial, a constant-velocity standard glide was presented. Then a variable-velocity comparison stimulus was presented; the comparison velocity took on one of three values. Comparison levels were varied parametrically on the to-be-judged dimension; thus values of the ignored dimension were adjusted in order to maintain the prescribed velocity. For the time-change task, listeners indicated whether the comparison was shorter or longer than the standard. For the pitch-change task, listeners indicated whether the comparison changed more or less in pitch than the standard.</p> 2013-08-06 02:44:20 neuroscience Cognitive neuroscience cognition Sensory systems Auditory system Sensory perception Applied mathematics statistics Biostatistics psychology Cognitive psychology Experimental psychology Psychophysics stimuli
