Binocular rivalry
Gestalt closure
Motion parallax
Visual cliff
#4
The primary auditory cortex is located in which lobe of the brain?
Frontal
Parietal
Temporal
Occipital
#5
Which of the following best describes the 'absolute threshold' of a sensory system?
The smallest amount of stimulus that can be perceived 50% of the time
The largest amount of stimulus that can be perceived without causing damage
The minimum difference between two stimuli required to detect a difference between them
The maximum capacity for sensory input in a given period
#6
Which principle of perceptual organization states that we tend to perceive objects that are moving together as belonging together?
Common fate
Good continuation
Figure-ground
Proximity
#7
What is the primary function of the auditory nerve?
To control eye movement
To regulate balance
To transmit sound information from the ear to the brain
To detect changes in temperature
#8
Which theory explains color vision as a result of the brain detecting differences in the responses of three types of cones?
Opponent-process theory
Trichromatic theory
Gate control theory
Feature detection theory
#9
The 'place theory' of hearing suggests that different frequencies of sound waves stimulate different locations on the:
Eardrum
Auditory nerve
Cochlea
Ossicles
#10
In the context of sensory adaptation, which of the following best describes the reason why people living near train tracks can eventually ignore the noise of passing trains?
The trains make less noise over time.
The auditory system becomes damaged by the loud noise.
The brain filters out non-essential sounds to focus on important stimuli.
The trains change their schedule to less frequent times.
#11
Which of the following is an example of a binocular cue for depth perception?
Texture gradient
Linear perspective
Retinal disparity
Relative size
#12
The McGurk effect best illustrates:
The dependence of perception on cultural experience
The interaction between hearing and vision in speech perception
The role of attention in sensory processing
The influence of expectations on sensory experience
#13
Which neural mechanism is primarily responsible for the detection of complex patterns and faces?
Rod cells
Cone cells
Ganglion cells
Feature detectors
#14
The phenomenon of 'phantom limb sensation' best supports which theory of pain?
Specificity theory
Pattern theory
Gate control theory
Biopsychosocial model
#15
The olfactory system is unique because:
It is the only sensory system that does not send its signals through the thalamus before reaching the cortex.
It can detect over a million different scents.
It directly connects to the hippocampus, facilitating emotional memory.
All of the above
#16
Which of the following best defines the term 'synesthesia'?
A condition in which stimulation of one sensory or cognitive pathway leads to automatic, involuntary experiences in a second sensory or cognitive pathway
A sensory disorder characterized by a lack of sensory processing
The process by which the brain combines information taken in through the senses to make a whole
The adjustment of sensory receptors to varying levels of stimuli
#17
The 'ventral stream' in visual processing is also known as:
The 'what' pathway
The 'where' pathway
The 'how' pathway
The 'why' pathway
#18
Frequency theory of hearing proposes that:
The frequency of the auditory nerve's impulses matches the frequency of a tone, enabling us to sense its pitch
Different sound frequencies stimulate different locations on the cochlear membrane
The amplitude of sound waves is directly proportional to the volume of sound
Sound is perceived through a series of mechanical vibrations in the ossicles
