chap 3 sensation and perception

What is transduction in the context of how we sense things?

• How the brain makes sense of what we see, hear, and feel

• Turning things from the outside world into signals our brain can understand

• Sending signals from our senses to our muscles

• How our sensory organs talk to each other

What is the primary function of sensory organs in the context of sensation?

• To create new sensory information

• To interpret sensory information

• To pick up energy in the environment and transmit it to the brain

• To store sensory information for later use

What is the absolute threshold in psychophysics?

• A) The maximum level of stimulus necessary for a person to detect its presence all the time

• B) The minimum level of stimulus necessary for a person to detect its presence at least ½ the time

• C) The average level of stimulus necessary for a person to detect its presence once

• D) The level of stimulus necessary for a person to detect its presence ¾ of the time

What is the field of study that explores how physical stimuli are translated into psychological experience?

• Psychodynamics

• Psychoanalysis

• Psychophysics

• Psychopathology

What does the Difference Threshold, also known as the Just Noticeable Difference, refer to in psychophysics?

• The maximum level of stimulus a person can tolerate

• The smallest change in stimulus necessary for a person to detect it at least half the time

• The initial point at which a stimulus is detected

• The point at which a stimulus becomes too intense and causes discomfort

What is sensory adaptation?

• Getting more sensitive to something the more you're exposed to it

• Feeling a change more intensely when something different happens

• Noticing something less the more you're exposed to it without change

• The way our senses get used to something if it keeps happening the same way

What is habituation in the context of sensation?

• The ability to detect a stimulus and the physical response to it

• Increase in response to a stimulus over time

• Decrease or stop responding to a stimulus that repeats or stays constant

• The process by which a person's sensation of a stimulus increases when it changes

What is perception in the context of the brain's ability?

• The ability of the brain to interpret raw sensations it takes in

• The brain's capacity to remember sensations

• The brain's function to create sensations

• The ability of the brain to ignore unnecessary sensations

What does perceptual constancy refer to?

• The brain's ability to change perception based on surroundings

• The brain's ability to maintain the same perception of an object even when surrounding conditions cause it to produce different sensations

• The brain's ability to perceive constant movement

• The brain's ability to constantly adapt to new sensations

Which aspects of perception are included under perceptual constancy?

• Size, Weight, and Texture

• Size, Shape, and Color

• Shape, Color, and Distance

• Color, Distance, and Weight
