Basic immediate experiences that a stimulus elicits in a sense organ are called: Sensations
The process of interpreting, organizing, and elaborating on the raw materials of sensation is called: Perception
Transduction can be defined as: process by which sensory organs transfer energy into electrochemical energy threshold.
The minimum physical intensity of a stimulus that can be perceived by an observer 50% of the time is: Threshold
A greater portion of the human brain is devoted to________ than any of out other senses. Vision
The __________ of visible light determines its hue, or color. Saturation
The film or image surface of a camera corresponds to the _______ if the eye retina
The focusing process in which the lens adjusts its shape depending on the distance between the eye and the object viewed in order to project a clear image onto the retina is called: Accommodation
The spot inside the eye where the ganglion cells meet to form the optic nerve is known as the: Blind spot
According to the opponent-process theory of color vision, the members of each system: inhibit vision of another
Loudness of sound is called_____ and expressed in units of ______ Volume, Decibles
Which theory states that perception of low tones depends on the frequency with which auditory hair cells in the inner ear trigger the firing of neurons in the auditory nerve? Frequency Theory of Pitch Discrimination
The sense of gustation is classified as a______ sense Taste
Where do you find the receptors for the olfactory sense? Nose
Which of the following is not one of the primary skin sensations? (touch, temperature, and pain) are skin sensations
Which of the following is cited as a reason why pain is understood so little? Gate-control theory
Pur perceptual tendency to group together objects that are near each other is called: Proximity
The principle of perceptual organization that attempts to explain how we organize information into meaningful wholes or Gestalts is called: Perceptual Grouping
The difference in the retinal image of an object as seen from each eye provides an important cue for depth which is called: Monocular Cues
Circadian rhythms vary around what type of cycle? Sleeping and Waking
The two key characteristics of brain waves are: Amplitude and Frequency
REM periods of sleep tend to _____ as the night wears on. lengthen
In a night's sleep, we move through successive sleep cycles that are each about: 90 minutes
Research depriving people of sleep for up to a week has shown that sleep-deprived individuals: hallucinate, delusions, double vision
The suggestion that it is better to study just prior to sleeping is based on which suggested function of sleep: Sleeping for memory
People tend to _____ when they are experiencing relationship conflicts, problems at work, or other emotionally stressful events. Dream
Frued theorized that dreams reflected: wishes or desires, manifest content
According to Frued, the manifest content of a dream: Disguised version of latent content. What actually happens in the dream.
A sleep disorder in which people fail to breathe regularly during sleep is: Sleep Apnea
A sleep disorder that may cause a person to awaken several hundred times a night in order to breathe is: Sleep Apnea
A sleep disorder in which a person falls asleep suddenly during normal waking activities is known as: Narcolepsy
Which sleep disorder has been linked to an abnormality in the brain mechanisms that control sleep and waking? Narcolepsy
Nightmare occur during______ sleep REM
In which of the following stages will sleep talking, sleep walking, and night terrors most likely occur? Stage 4
Sleepwalking almost always occurs during: Stage 3 or 4
Somnambulism is the technical term for: Sleepwalking
Hypnosis is believed by some researchers to be a state of: altered consciousness, deep relaxation
Evidence suggests that hypnosis can: Reduce pain, NOT athletic ability, memory, or relieve ailments
In a posthypnotic suggestion, the subjects: preform a variety of actions after returning to normal state.
Relatively enduring change in potential behavior that results from experience defines: Learning
The meat placed in a dog's mouth by Pavlov is referred to as the : UCS (Unconditioned Stimulus)
In what way does an unconditioned response differ from a conditioned response? One is controlled and the other is uncontrolled
When a child learns that pushing a button brings the elevator, the experts refer to this type learning as: Operant Conditioning
In classical conditioning, a conditioned response is defined as a: learned response to stimulus
Extinction of the CR in classical conditioning occurs when the: CS is repeated without UCS
After extinction had occurred in Pavlov's dogs, the bell could cause salivation when presented again at a later time. This phenomenon is called: Spontaneous recovery
A child is knocked down by a large friendly dog and is frightened. Later he sees his grandmother's dog and is frightened. The fear has been: Classically conditioned
Stimulus discrimination differs from stimulus generalization in that: more specific ex. fear of big dogs and not all dogs
The Law of Effect was proposed by: Thorndike
A stimulus that controls a response by signaling the availability of reinforcement is a: Discriminative stimulus
When an experimenter does not reinforce every correct response, it is referred to as: Partial reinforcement shedule
Reinforcers increase the probability that behavior will be: continued
Positive reinforcers are: stimulus presented after response that increases probability of response
Extinction will occur in operant conditioning when operant operant behavior is: discontinuing reinforcement
Which of the following is a primary reinforcer? Satisfies biological needs (hunger, thirst etc.)
In a ___ schedule, reinforcement is provided after a various number of correct responses have been made. VR, Variable Ratio
When behavior is demonstrated to a learner, the technique is called: Modeling
One basic difference between classical conditioning and operant conditioning is that: Elicit vs Emitted
Which of the following is desirable regarding the uses of punishment? Extinction of an action
