Psychology Unit 2 CHP.14,15,16

Question 1

Location of the gustatory cortex

Answer 1

The gustatory cortex is found on both the frontal and insular lobes.

Question 2

Retinal Disparity

Answer 2

Retinal disparity is one of the many ways in which humans can perceive depth. Retinal disparity is at play in many situations, such as driving or avoiding stepping off of a cliff.

Question 3

Constancy

Answer 3

the tendency for perceived objects to give rise to very similar perceptual experiences in spite of wide variations in the conditions of observation

Question 4

Photoreceptors

Answer 4

Photoreceptors are the cells in the retina that respond to light.

Question 5

Taste=Sensation, Flavour=Perception

Answer 5

Taste is the sensation produced when a substance in the mouth reacts chemically with taste receptor cells located on taste buds in the oral cavity, mostly on the tongue.

Perception of the flavour of foods is a complex process that involves the senses of smell and taste, and chemesthesis

Question 6

Binocular Depth cue

Answer 6

binocular cues are information (or cues) taken in by two eyes (binocular), versus one eye (monocular).

Question 7

Monocular Depth Cue

Answer 7

A monocular cue is a depth perception cue that can be perceived with only one eye.

Question 8

Binocular Depth cues vs Monocular Depth cues

Answer 8

Binocular depth cues consist solely of stereopsis. This is the name given to the ability of the human brain to combine the slightly different images received from both eyes in order to perceive depth. Monocular depth cues include size constancy, relative size and superimposition and rely on information received solely from one eye.

Question 9

Hypothesis

Answer 9

A hypothesis is an educated prediction that can be tested.

Question 10

Independent Variable (IV)

Answer 10

The independent variable is the characteristic of a psychology experiment that is manipulated or changed.

Question 11

Dependent Variable (DV)

Answer 11

The dependent variable is the variable that is being measured or tested in an experiment.

Question 12

Extraneous Variables

Answer 12

These are all variables, which are not the independent variable, but could affect the results (e.g. dependent variable) of the experiment.

Question 13

Sensation

Answer 13

Sensation refers to the process of sensing our environment through touch, taste, sight, sound, and smell.

Question 14

Perception

Answer 14

Perception is the process of recognising and interpreting sensory stimuli.

Question 15

Control groups

Answer 15

made of participants who do not receive the experimental treatment, randomly selected, usually resemble the experimental group.

Question 16

experimental groups

Answer 16

the group of participants who are exposed to the independent variable. They are compared to the control group.

Question 17

Participant selection (random)

Answer 17

when every single member of a population has an equal chance of being chosen as a subject.

Question 18

Participant selection (convenience)

Answer 18

non-probability sampling technique where subjects are chosen because of their convenient accessibility and proximity to the researcher.

Question 19

Participant selection (stratified)

Answer 19

researcher divides the population into separate groups, called strata. Then a probability sample (often a simple random sample ) is drawn from each group.

Question 20

Participant selection (Sample)

Answer 20

process of choosing a representative group from the population their studying. The target population is the total group of individuals where the sample might be drawn. A sample is the group of people who take part in the investigation, aka “participants”.

Question 21

Participant selection (population)

Answer 21

A population is a complete set of people with a specialised set of characteristics, The study population is the subset of the target population available for study.

Question 22

Experimental Designs (matched participants)

Answer 22

when you have different participants in two different conditions, but you match them according to certain variables, such as age, personality, gender, IQ etc.

Question 23

Experimental Designs (independent groups)

Answer 23

research method, multiple experimental groups are used and participants are only in one group. Each participant is only in one condition of the independent variable during the experiment

Question 24

Experimental Designs (repeated measures)

Answer 24

involves multiple measures of the same variable, taken on the same or matched subjects either under different conditions or over two or more time periods.
