AP Psychology FAQ 3.1-Principles of Sensation and Perception

The minimum amount of stimulation a person needs to detect a stimulus 50 percent of the time is called the

• adaptation threshold.

• difference threshold.

• subliminal threshold.

• absolute threshold.

• change threshold.

The principle that two stimuli must differ by a constant proportion for their difference to be perceived is known as

• the opponent-process theory.

• Weber's law.

• feature detection.

• sensory interaction.

• the difference threshold.

Diminished sensitivity to an unchanging stimulus is known as

• sensory accommodation.

• blindsight.

• sensory adaptation.

• transduction.

• equilibrium.

The feature detectors identified by Hubel and Weisel respond to specific aspects of ________ stimulation.

• vestibular

• visual

• auditory

• olfactory

• kinesthetic

The organization of two-dimensional retinal images into three-dimensional perceptions is called

• retinal disparity.

• monocular cues.

• perceptual constancy.

• depth perception.

• sensory interaction.

Which of the following is a binocular cue for the perception of distance?

• relative size

• retinal disparity

• relative motion

• linear perspective

• visual cliff

The convergence of parallel lines provides the distance cue known as

• interposition.

• closure.

• relative height.

• linear perspective.

• continuity.

Stereotypes are mental conceptions that can strongly influence the way we interpret the behaviors of individuals belonging to specific racial or ethnic groups. A stereotype is most similar to

• a feature detector.

• perceptual adaptation.

• a perceptual set.

• a difference threshold.

• gate-control theory.

Although Sue Yen sees her chemistry teacher several times a week, she didn't recognize the teacher when she saw her in the grocery store. This best illustrates the importance of

• monocular cues.

• context effects.

• proximity.

• linear perspective.

• perceptual adaptation.

Ohio State University pedestrians were more likely to cross streets unsafely if they were talking on a cell phone. This best illustrates the impact of

• place theory.

• gate-control theory.

• selective attention.

• the phi phenomenon.

• retinal disparity.
