“Executive control center”; judgment, planning, reasoning
Frontal Lobe
Contains the auditory cortex
Temporal Lobe
Controls the muscles needed for speech; Expressive language
Broca’s Area
Lobe that controls voluntary movements
Motor cortex (in back of frontal lobe!)
Parts of the limbic system
Hypothalamus: hunger, thirst, body temperature Amygdala: fear and aggression, threat detection center Hippocampus: new memories (explicit)
Famous for his theory on multiple intelligence; Identified at least 8
Howard Gardner
Intelligence proposed by Charles Spearman; A common level of intelligence that underlies all of our intelligence behavior
General (g) intelligence
What is emotional intelligence?
The ability to perceive, understand, manage, and use emotions
Proposed a triarchic theory of intelligence
Robert Sternberg; Analytical, creative, and practical intelligences
List Gardner’s intelligence types
Linguistic, logical-mathematical, musical, spatial, bodily- kinesthetic, intrapersonal, interpersonal, naturalist
The three measures of central tendency
Mean, median, and mode
What is the range of the following score distribution: 5, 10, 20, 30
25
In a normal curve, where are the mean, median, and mode located?
In the middle! For IQ, would be 100
A measure of how tightly clustered a group of scores is around their mean; Square root of variance
Standard Deviation
What is a z score?
Used to compare scores from different distributions; Converts scores into distance standard deviation “points”
Type of research in which humans or animals are studied in their natural context
Naturalistic observation
Studies one individual in depth through tests, interviews, observations
Case Study
In using surveys, a representative sample is one that is…
Representative of your entire population
Name that type of research. Comparing hours slept per night and GPA
Correlational
What is the difference between a longitudinal study and a cross sectional study?
Longitudinal: same group over time Cross sectional: studying same thing in different age groups
Group of psychologists who stressed that the whole is different than the sum of its parts; Studied organizational principles
Gestalt
The understanding that an object’s shape remains the same even though the angle of view makes the shape appear changed
Size constancy
What is relative size?
Smaller objects are further away, larger objects are clower
Appearance of motion created by lights turning off and on in a sequence
Phi Phenomenon
Name and explain your two binocular depth cues
Convergence: tension in eyes increase as objects come closer Retinal disparity: slightly different image projected onto the retina due to the separation of your eyes
Machine used to measure sleep waves
EEG
Body rhythm that occur on a 24 hour cycle
Circadian rhythms
What are sleep spindles?
Bursts of activity that occur during Stage 2
Cluster of neurons in the hypothalamus that receive information from the retina about light
Suprachiasmatic Nucleus
Chemicals involved in sleep
Adenosine: triggers sleepiness Melatonin: High levels help us get ready for sleep
