|
appled to a psychological measure, it refers to the measure's ability to assess the variable it is supposed to assess

|
|
hemispatial neglect
|
is a deficit in attention to the left side of space seen most often after right hemisphere brain injury. Damage with the brain areas in the parietal and frontal lobes is associated with the deployment of attention into left or right space. Behaviour associated with neglect include failure to find objects on the left side of a table or in a room

implicit motives
|
motives that can be activated and expressed outside of awareness
|
|
intrinsic motivation
|
enjoyment of and interest in an activity for its own sake
|
|
primary drive
|
an innate drive such as hunger, thirst, and sex
|
|
secondary drive
|
a drive learned through conditioning and other learning mechanisms such as modeling.
|
|
selt actualization
|
needs to express oneself, grow, and attain one's potential
|
|
opponent process theory
|
extreme emotions followed by their opposites (rebound effect). repeated stimulation results in habituation of original emotions. drug addiction, thrill seeking, puritanical values.
|
|
moods
|
relatively extended emotional states that do not shift attention or disrupt ongoing activities
|
|
schacter-singer theory
|
emotion involves 2 factors: physiological arousal and cognitive interpretation
|
|
alexithymia
|
the inability to recognize one's own feelings
|
|
james-lange theory
|
emotions originate in peripheral nervous system responses that the central nervous system then interprets
|

|
What is the difference between an operational definition of a variable and a theorectical definition?
|
theoretical definitions are clear descriptions of the variable and operational definitions are specific procedures used to measure the variable
|
|
Can science bring us certainty? why or why not?
|
No, sometimes there is bad data which means it isn't reliable or something bad valid measurements like led zepplin
|
|
what does it mean when 2 variables are positively correlate? negatively correlated?
|
positive correlation means that the higher individuals measure on one variable, the hgither they are likely to measure on the other and negative correlation means that the hgiher participants measure on one variable, the lower they will measure on the other.
|
|
what does it mean when a correlation coefficient for 2 variables is 0?
|
it means the two variables are not related. strong correlation is a positive or negative 1.0

|
what is the difference between a graded potential and an action potential?
|
graded potential is spreading voltage changes, which occur when the neural membrane receives a signal from another cell, strength diminishes and action potential is the firing of the neuron it has all or non quality.
|

what is a synapse?
|
connections between neurons occur here
|
|
central vs. peripheral
|
Central - brian & soubak cord
Peripheral- Neurons that convey messages to and from the cnetral nervous system |
|
Somatic vs. Automatic
|
Somatic - transmits sensory information to the central nervous system and carries out its motor commands
Automatic - conveys info to and from internal bodily structures that carry out basic life porcesses such as digestion and respiration. |
|
Sympathetic vs. Parasympathetic
|
Sympathetic - typically activated in response to threats
Parasympathetic - Supports more mundane, or routine, activities that maintain the body's store of enery |
|
What kind of situations cause the sympathetic nervous system to be come active?
|
fight or flight. responds to emergencies. it stops digestion, diverting blood away from the stomach and redirecting it to the muslcles, increases hearts rate and so on...
|
|
what kinds of situations cause the parasympathetic nervous system to become active?
|
emergencies, but the parasympathetic nervous system resumes control, reversing sympathetic effects and returning to the normal business of storing and maintaining resources.
|
|
What is the difference between association areas and primary areas of the cerebral cortex?
|
the primary areas process raw sensory information or initiate movement
the association ares are involved in complex mental processes such as forming perceptions, ideas, and plans |
|
what does the left hemisphere of the cortex specialize in? the right hemisphere?
|
the left functions the right and the right functions the left
|
|
What are the differences between Freud's 3 levels of consciousness (unconscious, preconscious, conscious)?
|
Conscious - involve subjective awareness of simuli, feelings, or ideas.
Preconscious - are not presnetly conscious but could be readily brought to consciousness, ex, smell of bacon cooking in the backgroung. unconscioius - inaccessible to consciousness because they would be too anxiety porvoking and thus have been repressed. |
