Which of the following are chemical senses?
touch
smell
taste
vision
hearing
The process by which our sensory receptor and nervous system receive and represent stimulus energies from our environment.
Perception
Transduction
Priming
Sensation
An example of difference threshold is:
hearing a clock ticking 20 feet away
gradually increasing light until a person can detect that it’s brighter
perceiving objects at different distances at different sizes
perceiving the length of lines based upon a starting point
An example of JND, or just noticeable difference, is
interrupting perception to the point where your brain cannot tell reality from fiction
gradually increasing light until a person can detect that it’s brighter
adding multiple lines to create an illusion to your perception
an addition of 3 lbs of books to an empty box vs. a 100 lbs box
Helps focus on informative, environmental chage through by-passing background chatter.
Perception Adaptation
Context Adaptation
Sensory Adaptation
Perceptual Set
An example of of signal-detection theory is:
an optical illusion may cause you to question truth
the Stroop effect with colors
the adjusting of your eyes to darkening of the lights in a movie theater
a radar operator tracking a plane, even when the blip is gone as the human can perceive it
The principle that, to be perceived as different, two stimuli must differ by a constant minimum percentage (rather than a constant amount)
Sensory Adaptation
Stimuli
Threshold
Weber's Law
Changing one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brain can interpret.
Transduction
Stimuli
Sensation
Subliminal
The weakest amount of a stimulus required to produce sensation is:
sensory adaption
signal-detection theory
difference threshold
absolute threshold
The effects of perceptual set show how experience helps us construct perception. But the immediate context also plays a role.
Culture
Context Effects
Perceptual Set
Sensory Adaptation
Mental Predisposition to perceive one thing rather than another.
Context Effects

An example of the attentive process is:
a radar operator tracking a plane, even when the blip is gone
the Stroop effect
the Ponzo illusion
the adjusting of your eyes to darkening of the lights in a movie theater
The pre-attentive process is a a method for extracting information automatically and simultaneously, while the attentive process:
shows relations between motivation, sensitivity, and decision-making
can vary in intensity and perception of people
is a procedure that considers only part of the stimuli presented at a time
is detected 50% of the time
Perception can be defined as-
how we perceive different things
how we interpret the information from the external world
how we sense things from the external world
Weber's Law states that:
the larger the stimulus, the larger the change required for the person to perceive the ratio change
the responsiveness of sense to changes to new events and changes in environments
the weakest amount of a stimulus required to produce sensation
the study of the relationship between the senses and the physical stimuli that causes them is vital to perception
Information processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations.
Top-down processing
sensation
perception
subliminal
The idea that the responsiveness of sense to changes to new events and changes in environments is known as:
Weber's Law
sensory adaption
signal-detection theory
attentive processes
The minimum stimulation needed to detect a particular stimulus 50 percent of the time.
Priming
Perception
Sensation
Absolute Threshold
Psychophysics is:
anytime a stimulus activates one of your receptors
the organization of sensory information into meaningful experiences
the study of the relationship between the senses and the physical stimuli that causes them
the responsiveness of sense to changes to new events and changes in environments
