Stimulus uncertainty affects velocity discrimination

Velocity discrimination thresholds were determined for 1 c/deg drifting gratings when uncertainty about the reference velocity was introduced by interleaving stimuli with different reference velocities from trial to trial. When drifting gratings with reference velocities spanning 4 octaves (1-16 deg/sec) were mixed randomly within a series of trials, the velocity discrimination threshold for a ...

Stimulus Equivalencies Through Discrimination Reversals

The sensory systems of advanced animals frequently input more stimulus infonna-tion into the nervous system than the motor system can possibly output as behavior patterns. This bottleneck demands a drastic infonnation reduction. Two types of reduction can be distinguished: selective attention involving behavioral context-dependent infonnation censoring (as when during sexual behavior food stimu...

Velocity discrimination in scotopic vision

To characterize scotopic motion mechanisms, we examined how variation in average luminance affects the ability to discriminate velocity. Stimuli were drifting horizontal sine-wave gratings (0.25, 1.0 and 2.0 c/deg) viewed through a 2 mm artificial pupil and neutral density filters to produce mean adapting levels from 2.5 to -1.5 log photopic trolands. Drift temporal frequency varied from 0.5 to...

Spatial Layout Affects Speed Discrimination

We address a surprising result in a previous study of speed discrimination with multiple moving gratings: discrimination thresholds decreased when the number of stimuli was increased, but remained unchanged when the area of a single stimulus was increased [Verghese & Stone (1995). Vision Research, 35, 2811-2823]. In this study, we manipulated the spatial- and phase relationship between multiple...

Discrimination learning with variable stimulus 'salience'

BACKGROUND In nature, sensory stimuli are organized in heterogeneous combinations. Salient items from these combinations 'stand-out' from their surroundings and determine what and how we learn. Yet, the relationship between varying stimulus salience and discrimination learning remains unclear. PRESENTATION OF THE HYPOTHESIS A rigorous formulation of the problem of discrimination learning shou...
