Additional Psychology Flashcards

 


 

Cards

Term
Motivation
Definition

the process of starting, directing, and maintaining physical and psychological activities.

Term
Preference, Intensity, and Persistance
Definition

preference- one activity chosen over another

Intensity- vigor of the response

Persistance- persistance of organized patterns of actions towards a goal

Term
Types of Motives
Definition

Primary- simple, serves biological needs, common to all animals

Complex- learned behaviors, typically involve social interaction

Term

Hunger as a motive

- Blood Glucose Levels

- Hypothealamic involvement

- External Cues

 

 

Definition

Blood Glucose levels- hunger motivates you to supply enough glucose

Hypothalamic involvement

1. Lateral portion- tells us what to eat

2. Ventromedial portion- tells us when to stop

External Cues- Diet and social factors                                                       

 

 

 

 

 

Term
Obesity and Anorexia
Definition

Obesity- lower metabolic rate, genetics (twin studies tested), externality hyporthesis

Anorexia- three stages

1. Concern of physical appearance

2. increased fear of eating and becoming fat

3. Admission of problem, increased food intake


Term
Arousal as a motive
Definition

Humans are motivated to maintain an optimal level of arousal.

Easy tasks- high optimal level of arousal

Moderately difficult tasks- medium level of arousal

Difficult tasks- low level of arousal

Term
2 types of Conditioning
Definition

Conditioning is learning.

1. Classical- learning assocation between 2 stimuli (learner acted on by environment)

2. Operant- learning assocation between behavior and consequences (learner operates on environment)

Term
Unconditioned Stimuls and Unconditioned Response
Definition

US: stimulus elicits reflexive response (smell food)

UR: automatic response (salivating)

Term
Conditioned stimulus and Conditioned Response
Definition

cs: initially neutral stimulus paired with unconditioned stimulus (Bell)

cr: learned response (salivating to bell)

Term
Extinction
Definition
Conditioned response disappears
Term
Stimulus generalization
Definition
Conditioned response appears with similar stimuli (different bells)
Term
Law of effect
Definition

Response followed by a reward > stregnethens 

Response followed by punishment> weakens

Term
Reinforcement 
Definition
increase of behavior (Skinner)
Term
Positive reinforcement
Definition
when a response produces something
Term
Negative Reinforcement
Definition
response removes something
Term
Punishment
Definition
Decrease of a behavior
Term
Positive punishment
Definition
addition of something decreases behavior
Term
Negative Punishment
Definition
taking away something decreases behavior
Term
Psychophysics
Definition
relationship between sensory experience and physical properties of stimuli
Term
2 Types of thresholds
Definition

Absolute- smallest amount of energy a person can detect

Difference- smallest difference in stimulation that can be detected when two things are compared

Term
Weber's Law
Definition
the concept that a just-noticeable difference in stimulus is proportional to the magnitude of the original stimulus
Term
Vestibular Sense
Definition
Bodily orientation with respect to gravity
Term
Kinesthetic
Definition
Bodily orientation with respect to rest of body
Term
Cutaneous
Definition
Touch, pressure, cold, warmth, pain
Term
Taste
Definition
chemical substance of food interacts with receptors on tongue
Term
Smell
Definition
Chemical substances in air interact with receptors of the olfactory epithelium
Term
Hearing
Definition
Sound waves moving through air or other substance that stimulate audiotry receptors in ears
Term
Characteristics of Sound waves
Definition

Amplitude- loudness (Db)

Frequency- pitch (Hz)

Complexity- timbre (difference of sound)

Term
Vision
Definition
dominant sense in humans
Term
Cornea
Definition
clear covering of eye
Term
Pupil
Definition
opening of eye
Term
Iris
Definition
Colored portion of eye, muscles change size of pupils
Term
Lens
Definition
focuses light
Term
Retina
Definition
light sensitive region of eye where photorecepors dwell
Term
Cones
Definition
day vision and color, concentrated in fovea
Term
Rods
Definition
night vision and achromatic vision
Term
Myopia
Definition
near sightedness, image is only what is right in front of you
Term
Hyperopia
Definition
far sightedness,short eyeball, lens not powerful enough, focus better on things far away
Term
Fovea
Definition
where the light is directed towards. If light is not focused on fovea but on blind spot you become blind
Term
Characteristics of Light
Definition

Hue- color we perceive (wavelength)

Brightness- intensity or amount of light you see

Saturation- vividnss or purity of color

 

Term
Binocular Disparity
Definition
both eyes see a slightly different view of the same object
Term
Sensation
Definition
physical characteristics/stimulus
Term
Perception
Definition
Interpretation inside of our head
Term
Depth cues
Definition
features of stimuli indicate how far an object is from the observer or another object
Term
Binocular cues
Definition
require both eyes to see cue, used for CLOSE objects
Term
Monocular Cues
Definition
only requires one eye, used for FAR objects
Term
Gestalt's laws of grouping
Definition

1. proximity- objects close together are perceived to be in the same group

2. Similarity- similar objects grouped together

3. Continuation- fill gaps when lines are interrupted (hot dog)

4. Closure- when a familiar object is partially covered up, we imagine the rest (Abe)

Term
2 types of Memory
Definition

Episodic- detailed memories from personal experience

Semantic- memories of general knowledge (facts and concepts)

Term
Memory: Encoding
Definition
converting external info into code that brain can understand
Term
Memory: Storage
Definition
encoded data is stored until we need it again
Term
Memory: Retrieval
Definition
getting stored info out of memory
Term
Declarative memory
