Focuses on observable behavior.
Examines how people understand and think about the world.
Brain is like a computher; information processing.
Contends that people can control their behavior and that they naturally try to reach their full potential.
Rogers;Maslow;free will
Believes behavior is motivated by inner, unconscious forces over which the person has little control.
Scientific Method
The approach used by psychologits to systematically acquire knowledge and understanding about behavior and other phenomena of interest.
Investigator simply observes some naturally occuring behavior and does not make a change in the behavior
Survey Research
A sample of people chosen to represent a larger group of interest are asked a series of questions about their behavior, thoughts, or attitudes.
Case Study
in-depth, intensive investigation of an individual or a small group of people.
Correlational research
Positive correlation: one increases, the other increases
Negative correlation: one increases, the other decreases
Informed Consent
Participants must sign document affirming that have been told the basic outlines and are aware of waht their participation will involve, what risks the experiment may hold, and the fact that their participation is purely voluntary and they may terminate at any time.
Experimental bias
Factors that distort the way the independent variable affects the dependent variable in an experiment.
False treatment. The decaf.
Double-blind procedure
No one knows who drank the real coffee.
Nerve cells, the basic elements of the nervous system.
A cluster of fibers at one end of a neuron that receive messages from other neurons
The part of the neuron that carries messages destined for other neurons.
Terminal Buttons
Small bulges at the end of axons that send messages to other neurons.
Myelin Sheath
A protective coat of fat and protein that wraps around the axon.
Chemicals that carry messages across the synapse to the dendrite of a receiver neuron.
In brain.
In brain, spinal cord.
muscle movement.
In brain.
Muscle and mental disorders;Parkinson's disease.
In brain, spinal cord.
Pain suppresion, pleasureable feelings, appetities.
In Brain, spinal cord.
The part of the brain that controls bodily balance.
The part of the brain located in the middle of the central core that acts primarilly as a busy relaty station, mostly for information concerning the senses.
Tiny part of the brain, located below the thalamus, that maintains homostasis and produces and regulates vital, basic behavior such as eating, drinking, and sexual behavior.
Reticular Formation
The part of the brain from the medulla through the pons made up of groups of nerve cells that can immediately activate other parts of the brain to produce general bodily arousal.
Cerebral Cortex
The "new brain," responsible for the most sophisticated information processing in the brain; contains the lobes.
Initial storage of memory.
Pituitary Gland
Growth, hormones.
Regulates Breathing and Circulation.
Temporal Lobe
Sound, understanding language.

Speaking. Produce speech verbally
Can't recognize faces.
Form of energy in the environment ithat sense organs can detect
Sense organs detect; Causes a chemical rxn
The interpretation and integration of the senses
Absolute threshold
Smallest intensity of a stimulus that must be present for the stimulus to be detected by the human receptor cells
Just Noticeable Difference
Smallest difference in stimulation required to discriminate 50% of the time
Sensory adaptation
An adjustment in sensory capacity of sensory responsivness
Weber's Law
Two stimuli must differ by a constant minimum percentage to be perceived as different.
VISION: Stimuli
Light waves
VISION: Sensation
Visual Receptors Rods & Cones transmit light wave energy into electrical impulses
VISION: Perception
Impulses sent to occipital lobe & Primary visual cortex and then are interpreted.
Black/White/Gray. 120 million. FXN well under low illumination. Receptors in the retina that are sensitive to light
6 million. Color perception. Require large amount of light. In fovea.
Opponent-process Theory of Color Vision
The theory that receptor cells for color are linked in pairs, working in opposition to each other.
Ex: Yellow, Green, Black Flag
HEARING: Stimuli
Sound Waves
HEARING: Sensation
Movement of Hair cells
HEARING: Perception
When it hits the Temperal Lobe
A series of principles that describe how we organize bits and pieces of information into meaningful wholes
A need to fill in the blanks.
Grouping things according to proximity
Elements similar in appearance we perceive as grouped together.
Looking for the simplest shape first
Top-Down Processing
Perception that is guided by higher-level knowledge, experience, expectations, and motivations
Bottom-Up Processing
Perception that consists of recognizing and processing information about the individual components of stimuli
Perceptual Constancy
Physical objects are perceived as unvarying and consistent despite changes in their appearance or in the physical environment.
Awareness of one's surroundings, of one's self, of one's thoughts and feelings
