The what and where in visual masking.

A metacontrast mask suppresses the visibility of, without influencing the reaction time (RT) to, the target. We investigated whether this dissociation results from a sensori-motor pathway immune to masking effects or from the characteristics of stimulus ...

Adult age differences in unconscious transference: source confusion or identity blending?

Eyewitnesses are known often to falsely identify a familiar but innocent bystander when asked to pick out a perpetrator from a lineup. Such unconscious transference errors have been attributed to either identity confusions at encoding or source retrieval ...

Change in perceptual form attenuates the use of the fluency heuristic in recognition.

Four experiments (total N=295) were conducted to determine whether within-modality changes in perceptual form between the study and the test phases of an experiment would moderate the role of the fluency heuristic in recognition memory. Experiment 1 ...

How do monkeys view faces?--A study of eye movements.

Face perception plays a crucial role in primate social communication. We have investigated the pattern of eye movements produced by rhesus monkeys (Macaca mulatta) as they viewed images of faces. Eye positions were recorded accurately using implanted eye ...

No evidence for accurate visuomotor memory: systematic and variable error in memory-guided reaching.

The authors explored whether the motor system has access to highly accurate information about the aiming environment after visual occlusion. Participants (N = 14) reached to 1 of 3 midsagittal targets in 4 visual conditions (open-loop, brief-delay, ...

Two stages in crossmodal saccadic integration: evidence from a visual-auditory focused attention task.

Saccadic reaction time (SRT) toward a visual target stimulus was measured under simultaneous presentation of an auditory non-target (accessory stimulus). Horizontal position of the target was varied (25 degrees left and right of fixation) as well as ...

Temporal parameters and time course of perceptual latency priming.

Visual stimuli (primes) reduce the perceptual latency of a target appearing at the same location (perceptual latency priming, PLP). Three experiments assessed the time course of PLP by masked and, in Experiment 3, unmasked primes. Experiments 1 and 2 ...

Oblique stimuli are seen best (not worst!) in naturalistic broad-band stimuli: a horizontal effect.

People with normal eyesight typically see horizontal and vertical gratings better than oblique gratings (Psychological Bulletin 78 (1972) 266; Perception 9 (1980) 37). In the present study we investigated whether this oblique effect anisotropy is still ...

Syllabic length effects in visual word recognition and naming.

Two experiments investigated the role of the number of syllables in visual word recognition and naming. Experiment 1 (word and nonword naming) showed that effects of number of syllables on naming latencies were observed for nonwords and very ...

Direct parameter specification of an attention shift: evidence from perceptual latency priming.

In the direct parameter specification (DPS) mode of sensorimotor control, response parameters can be specified by stimuli that are not consciously perceived [Psychological Research/Psychologische Forschung 52 (1990) 207]. DPS is contingent on the current ...
