Exam points

  • distinguish rods for peripheral vision from cones and foveal vision for colour or fine detail
  • apply lens accommodation to explain how visual images are brought into sharper focus
  • use wavelength and opponent-process effects to identify perceived colour or afterimages
  • apply feature detectors or occipital-cortex processing to recognition of visual stimuli

AP Psychology 1.6 B Explain How the Structures and Functions of the Visual Sensory System Relate to Behavior and Mental Processes Questions question 1

[Maximum number: 2]

A researcher designs a study to investigate the effect of feedback on perception of incomplete visual figures.

Each participant stares at the center of a screen while the researcher briefly projects incomplete geometric figures one at a time at random positions on the screen. The participant's task is to identify each incomplete figure. One group of participants receives feedback on the accuracy of their responses. A second group does not.

The researcher compares the mean number of figures correctly identified by the two groups.
