  • Front
  • Back
It is involved in movement and fine motor learning; It also affects balance and slurred speech and staggering
Schacter-Singer Theory
Emotion involves two factors: physiological arousal and cognitive interpretation
Side-steps the mind-body problem
What is the main function of a dendrite?
Receives inputs from other cells
James-Lange Theory
Emotions originate in peripheral nervous system responses that the central nervous system then interprets
How long is a normal sleep cycle?
90 minutes
Inability to recognize one's own feelings
What stage is associated with alpha waves?
As the person closes the eyes and relaxes-state of meditation
What stage is associated with theta waves?
Stage 1-eye movements are absent
Individuals are unaware of their capacity to see
Main function of the occipital lobe
Located in the rear portion of cortex
Specialized for vision
receive visual input from thalamus
Personality traits associated with hypnotizability
Able to form vivid visual images, readily absorbed in fantasy, daydreams, and movies
Main function of parietal lobe
Located in front of the occipital lobe
Sense of touch, detecting movement in environment, locating objects in space and experiencing one's own body as it moves through space
Main function of temporal lobe
Located on the lower side portions of cortex
Important in hearing and language
Wernicke's Area is located here
Cerebral cortex
80% of brain's mass; allows flexible construction of sequences of voluntary movements involved in activities such as playing a piano; pertmits subtle discriminations among complex sensory patterns; makes symbolic thinking possible
Limbic System
Set of structures w/ diverse functions involving emotion, motivation, learning, and memory; includes amygdala, septal area, and hippocampus
Myelin Sheath
Facilitates transmission of info to other neurons
Scientific study of mental processes and behavior; types are experimental and applied(more common)
Implicit motives
Motives that can be activated and expressed outside of awareness
Difference between theoretical and operational definition
theoretical def-clearly describes the variable
operational def-defines the procedures used to measure the variable
Correlation Coefficient
Measures the extent to which 2 variables are related; can either be pos. or negative
Intrinsic Motivation
Enjoyment of and interest in an activity for its own sake
Heritability Coefficient
Quantifies extent to which variation in trait across individuals can be accounted for by genetic variation
What is the function of an axon?
Transmits info to other neurons
Central v. Peripheral
Two divisions of the nervous system; central-brain and spinal cord; peripheral-neurons that convey messages to and from central nervous system
Where connections between neurons occur; the most important functional unit of the nervous system
Difference between graded and action potential?
Action potential is not cumulative; in graded potential, strenth diminishes as they travel along cell membrane
Somatic v. Autonomic
2 subdivisions of the peripheral nervous system; somatic-transmits sensory info to central nervous system and carries out motor commands; autonomic-conveys info to and from internal bodily structures that carry out basic life processes
Function of sadness
Conserve energy and maintain attachments
Motives to help to express oneself and grow
After one cycle, what happens to NREM sleep compared to REM sleep
NREM time decreases and there is more REM sleep
As you get older, what happens to the proportion of time in REM sleep?
Broca's Area
Located in the frontal lobe @ base of motor cortex
Specialized for movements of moouth and tongue necessary for speech production
Somotosensory Cortex
Primary area of the parietal lobe; divides parietal lobe from frontal lobe; one section registers sensations from hand, foot, and so forth; complex visual processing; map of body
Which stage do we have vivid, storylike dreams?
REM sleep
What does left and right hemi specialize in?
left-language, logic, complex motor behavior, and aspects of consciousness; right-nonlinguistic functions such as forming visual maps of the environment
What stage is associated with beta waves?
normal waking brain activity
Main function of amygdala
almond-shaped; involved in many emotional processes, especially learning and remembering emotionally significant events
Statistical Significance
Result was probably not due to chance
Extent to which findings of experiment apply to intended population
What kinds of situations cause the parasympathetic nervous system to become active?
certain breathing techniques
Sympathetic v parasympathetic
sympa-emergency system
parasympa-business as usual(regulate blood sugar, secreting saliva)
Validity and the types of validity
measure's ability to assess the variable that it is supposed to assess; face-whether or not the measure appears as though it measures what its suppose to measure; construct-degree to which a measure actually assesses what it claims to measure; criterion-degree to which a measure allows a researcher to distinguish among groups on the basis of certain behaviors
Goes w/ mind-body problem
What kinds of situations make sympathetic nervous system to become active?
chased by someone; giving a speech
Want theory to be falsifiable; ability of a theory to be proven wrong as a means of advancing science
Main function of hindbrain
Control supply of air and blood to cells in body and regulate arousal level; bottom part of the brain connected to the spinal cord
Function of Disgust
Protection from bacteria
Main function of hippocampus
storing new information in memory so that person can later consciously remember it. Remember H.M.
Main function of motor cortex
Initiates voluntary movement; primary zone of frontal lobe
Function of anger
Leads to withdrawal; show greater relative activity in left frontal; hurt people who might hurt us
inability to sleep
Body's tendency to maintain a relatively constant state that permits cells to live and function
Primary Drive
innate drive such as hunger, thirst,and sex
Secondary drive
drive learned through conditioning and other learning mechanisms such as modeling
systematic way of organizing and explaining observations
Reliability and types of them
measure's ability to produce consistent results; test-retest, interitem reliabilty, and interrator
chemicals that transmit info from one cell to another
Frontal lobe
involved in number of functions, including movement, attention, planning, social skills, abstract thinking, memory, and some aspects of personality
motives for achievement, autonomy, mastery, power,and other self-oriented goals
motives for connectedness w/ others
deep relaxation and suggestibility
Difference between manifest and latent
manifest-story line of dream
latent-underlying meaning of dream
Cannon-Bard Theory
Emotion-inducing stimuli simultaneously elicit both an emotional experience and bodily responses
relatively extended emotional states
Function of joy
Pos. reinforcement for behavior that conferred as a reproductive advantage to our ancestors
Wernicke's area
located in left temporal lobe; important in language comprehension
Subliminal messages
Make you buy something; hidden messages
Ex. hearing of a sound produces visualization of a color
Opponent-Process Theory
argues that all colors are derived from three antagonistic color systems: black-white, blue-yellow, red-green; extreme emotions followed by their opposites(rebound effect)
