Stimulus selectivity of figural aftereffects for faces.
Viewing a distorted face induces large aftereffects in the appearance of an undistorted face. The authors examined the processes underlying this adaptation by comparing how selective the aftereffects are for different dimensions of the images including size, spatial frequency content, contrast, and color. Face aftereffects had weaker selectivity for changes in the size, contrast, or color of th...
متن کاملFigural aftereffects in the perception of faces.
We examined figural aftereffects in images of human faces, for which changes in configuration are highly discriminable. Observers either matched or rated faces before or after viewing distorted images of faces. Prior adaptation strongly biases face perception by causing the original face to appear distorted in a direction opposite to the adapting distortion. Aftereffects transferred across diff...
متن کاملIgnored Faces Produce Figural Face Aftereffects
Following adaptation to faces with contracted (or expanded) internal features, faces previously perceived as normal appear distorted in the opposite direction. This figural face aftereffect suggests face-coding mechanisms adapt to changes in the spatial relations of features and/or the global structure of faces. Here, we investigated whether the figural aftereffect requires spatial attention. P...
متن کاملProprioceptive Movement Illusions Due to Prolonged Stimulation: Reversals and Aftereffects
BACKGROUND Adaptation to constant stimulation has often been used to investigate the mechanisms of perceptual coding, but the adaptive processes within the proprioceptive channels that encode body movement have not been well described. We investigated them using vibration as a stimulus because vibration of muscle tendons results in a powerful illusion of movement. METHODOLOGY/PRINCIPAL FINDIN...
متن کاملFigural Aftereffects and Validity of the Hoffer-Osmond DiagnosticTest
One problem confronting diagnostic tests is the extent to which different diagnostic groups obtain similar scores, or the degree to which patients with the same diagnosis obtain extreme scores on a test. An example of the latter is the HofferOsmond Diagnostic Test or HOD on which approximately 70 percent of schizophrenic patients obtain relatively high scores (above established cutoff points) a...
