Correlational studies are used to look for relationships between variables. The three possible results are either a positive correlation, negative correlation, or no correlation. The correlation coefficient is a measure of correlation strength and can range from -1.00 to 1.00.

Q

31
Q

Why is the corpus collossum surgically removed?

A

The corpus callosum was surgically severed in hopes that it would reduce seizures in patients with uncontrollable epilepsy.

32
Q

Top - Down Processing

A

processing guided by higher-level mental processes, as when we construct perceptions drawing on our experience and expectations.

33
Q

Perception

A

the process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events.

34
Q

Sensory Adaptation

A

diminished sensitivity as a consequence of constant stimulation.

35
Q

Transduction

A

conversion of one form of energy into another. In sensation, the transforming of stimulus energies into neural impulses.

36
Q

Parallel Processing

A

the processing of several aspects of a problem simultaneously; the brain’s natural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving.

37
Q

Opponent Process Theory

A

the theory that opposing retinal processes (red-green, yellow-blue, white-black) enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green.

38
Q

Kinesthesis

A

system for sensing the position and movement of individual body parts.

39
Q

Cocktail Party Effect

A

the phenomenon of being able to focus one’s auditory attention on a particular stimulus while filtering out a range of other stimuli, much the same way that a partygoer can focus on a single conversation in a noisy room.

40
Q

Gestalt

A

An organized whole. Gestalt psychologists emphasized our tendency to integrate pieces of information into meaningful wholes.

41
Q

Closure

A

The ability for the human mind to close gaps in images to form complete and closed objects. Ex. Triangle theory

42
Q

Depth Perception

A

The ability to see objects in three dimensions although the images that strike the retina are two-dimensional; allows us to judge distance.

43
Q

Schema

A

A concept or framework that organizes and interprets information. (pg. 147)

44
Q

Parapsychology

A

The study of paranormal phenomena, including ESP and psychokinesis (pg. 264)

45
Q

Example of Subliminal Stimulation

A

Subliminal messages that only your deep consciousness can recognize.

46
Q

Example of Difference Thresholds

A

Feeling small amounts of sand being added to your hand.

47
Q

Components of Brightness

A

Wavelength is the distance from peak to to the next - determines color.

48
Q

Classification of smell

A

Olfaction (smell) and gustation (taste) are senses that respond to minute traces of chemical molecules that foods and many other substances emit.

49
Q

Dominant Sense

A

The different senses actual can be heard in conservations with people. When you listen to people you can easily pickup their dominant sense. Normally, seeing (visual), hearing (auditory) and touching (kinesthetic) are the senses that are strongest and show up the most in conversation. Usually it is the sense of smell which people normally have the strongest bond with.

50
Q

Depth Perception Tested in labs

A

the babies that walk across a glass pane over a “cliff” and they note whether or not the baby will crawl right over it or notice the sudden drop and stop before.

51
Q

Perceptual adaptation

A

This refers to the ability of the body to adapt to an environment by filtering out distractions

52
Q

conciousness

A

your individual awareness of your unique thoughts, memories, feelings, sensations, and environment

53
Q

age regression

A

Have you ever seen a movie in which some characters supposedly had something happen to them when they were young and some therapist says he/she will hypnotize the person so they can “go back” in time and remember the thing that happened? Well, that’s basically what age regression is, its reliving a past experience that you blocked out

54
Q

withdrawal

A

the distress and cravings that occur when people stop using an addictive substance

55
Q

spontaneous recovery

A

after extinction, the sudden reappearance of a previously extinguished response.

56
Q

Generalization

A

Generalization refers to a process within operant and classical conditioning, where a conditioned response (CR) starts occurring in response to the presentation of other, similar stimuli, not just the conditioned stimulus (CS). For example, a dog is trained to sit (CR) when you give the command, “sit” (CS). Soon after that, the dog might sit when you say “hit”, “bit”, and “kick”. In this case, the CR (sitting) is not only done to the CS (the command, “sit”) but also to commands that are similar.

57
Q

discrimination

A

In classical conditioning, it is the ability to differentiate between a conditioned stimulus and other stimuli that have not been paired with an unconditioned stimulus

58
Q

extinction

A

When a conditioned response weakens or disappears

59
Q

Purpose of Melatonin

A

Hormone that induces sleep

60
Q

characteristics of dreaming

A

REM (Rapid Eye Movement) Sleep. It is the 5th stage of sleep. There is an increased rate of respiration and brain activity.

61
Q

characteristics of delta waves

A

Takes place during Stage 3 and 4 of sleep

62
Q

Symptoms of sleep apnea

A

Not breathing during sleep is probably a big one. Other ones may include: sleepiness or lack of energy during the day, waking up with a sore/dry throat, morning headaches, waking up with a choking or gasping sensation, forgetfulness, mood changes, and a decreased interest in sex.

63
Q

synaptic gap

A

aka cleft

tiny gap at the junction between axon tip and sending neuron

64
Q

action potential

A

a neural impulse; a brief electrical charge that travels down an axon. The action potential is generated by the movement of positively charged atoms in and out of channels in the axon’s membrane

65
Q

Synapse

A

The junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron.

66
Q

myelin sheath

A

a layer of fatty tissue segmentally encasing the fibers of many neurons; enables vastly greater transmission speed of neural impulses as the impulses hops from one node to the next

67
Q

motor neurons

A

neurons that carry outgoing information from the central nervous system to the muscles and glands

68
Q

role of iris

A

a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening
controls the light passing through the pupil

69
Q

function of the retina

A

the light sensitive inner surface of the eye, containing the receptor rods and cones plus layers of neurons that begin the processing of visual information
upside down image passes onto the retina

70
Q

components of the optic nerve

A

nerve that carries neural impulses from the eye to the brain
ganglion fibers
creates a blind spot when the optic nerve leaves the eye

71
Q

components of the cochlea

A

coiled, bony, fluid filled tube in the inner ear through which sound waves trigger nerve impulses
nerve impulses trigger ripples in the liquid which creates basilar movement, with hair cells

72
Q

drug tolerance

A

the diminishing effect with regular use of the same dose of a drug, requiring the user to take large and larger doses before experiencing the drug’s effect

73
Q

marijuana

A

hallucinogen

THC

74
Q

primary reinforcer

A

an innately reinforcing stimulus, such as one that satisfies a biological need

75
Q

secondary reinforcer

A

a stimulus that gains its reinforcing power through the association with a primary reinforcer

76
Q

punishment

A

an event that decreases the event that it follows.
