Which of the following are true of synesthesia?
It involves mixing of the senses.
It is rare.
How does sensation occur?
The sense organs translate environmental stimuli into nerve impulses and then send them to the brain.
What is the process organisms use to interpret and assign meaning to the world?
Perception
Which sensory process is the sensory detection process used by our organs to respond to and translate environmental stimuli into nerve impulses that get sent to the brain?
Sensation
The sensory process begins with information received from a
stimulus
The conversion of energy from one form to another form is called
Transduction
Dr. Lenz is a researcher in the field of
___________and is studying the relationship between physical stimulation and subjective perception.
psychophysics
Which sensory process is the sensory detection process used to “make” sense of what we are experiencing?
Perception
What are the two kinds of sensitivity that the field of psychophysics is concerned with?
The absolute limits of sensitivity
Differences between stimuli
Sensation becomes perception from the reception and translation of physical impulses into a(n)
nerve impulse
The lowest intensity at which a stimulus can be detected 50 percent of the time is called
absolute threshold
The process where characteristics of a stimulus are converted into nerve impulses is called
transduction
The scientific area of _________
studies the relationship between the physical characteristics of stimuli and sensory capabilities.
psychophysics
A(n) ______ stimulus is one that is so weak or brief that it can be received by the senses but not consciously perceived.
Subliminal
Signal
__________ theory is concerned with the factors that influence sensory judgments.
detection
If someone can detect the light from a candle 30 kms away at least half of the time, this is an example of
Absolute Threshold
Consumer behaviour _____ be controlled by subliminal stimuli.

The theory that is concerned with the factors that influence sensory judgments is
signal detection theory
Paul jumps into the river to go swimming. At first the water is so cold he starts shivering. Over time he yells to his friends to come on in the water feels great. This is an example of
sensory adaptation
Which law states that the difference threshold or jnd, is directly proportional to the magnitude of the stimulus with which the comparison is being made?
Weber’s law
Images projected directly on the
________ appear for a time in their entirety and then vanish and reappear as parts of the original stimulus.
retina
Weber’s fraction for detecting differences in the loudness of a sound is
1/20

highest in wavelength to the lowest
