(36 cards)
The minimum stimulus energy needed to detect a stimulus 50% of the time is called the:
Absolute Threshold
Weber’s law describes the relationship between stimulus intensity and:
Difference threshold
Sensory adaptation occurs when:
Sensitivity decreases over time
The structure in the eye that changes shape to focus light is the:
Lens
Rods in the retina are most sensitive to:
Dim light
The trichromatic theory explains color vision at the level of the:
Retina
Opponent-process theory accounts for:
When colours linger after looking too long
Afterimages
The pinna and ear canal are parts of the:
Outer ear
The ossicles transmit vibrations from the eardrum to the:
Oval window
Place theory explains pitch perception by:
Activity along the basilar membrane
The vestibular system monitors:
Body position and balance
Gate-control theory relates to:
Pain modulation
The McGurk effect illustrates:
When what you see is different from what you here - what does this cause?
Multisensory integration
Perceptual constancy allows us to perceive objects as stable despite:
Changing sensory input
The Stroop effect demonstrates interference in:
Color-naming tasks
Depth cues such as convergence and binocular disparity are:
Binocular
The phi phenomenon underlies:
Motion perception
The phi phenomenon is an optical illusion where stationary objects appear to move when they are rapidly flashed on and off in a sequence
The cocktail party effect is an example of:
describes the brain’s remarkable ability to focus on a single conversation in a noisy environment, selectively ignoring other sounds
Selective attention
Figure–ground organization is a principle of:
Visual perception
Gestalt law of proximity states that elements near each other:
Are perceived as a group
Top-down processing involves:
Pre-existing knowledge being used to understand new knowledge
Cognitive expectations
Bottom-up processing starts with:
Sensory data
Ambiguous figures illustrate:
The ambiguous figures are a visual illusion in which one picture can be seen different ways.
Multistability
Multistability in psychology refers to the perceptual phenomenon where a single, unchanging stimulus is interpreted in multiple, alternating ways.
Proprioception informs us about:
Body position
