-
What goals of psychology are basic research?
description, explanation, prediction
-
What goals of psychology are applied research?
Influence (control)
-
Basic vs. applied research
Basic: research conducted to seek new knowledge and to explore and advance general scientific understanding
Applied: research conducted specifically to solve practical problems and improve the quality of life.
-
Types of descriptive research
- 1. Naturalistic Observation
- 2. Laboratory Observation
- 3. Case Study
- 4. Surveys
-
Naturalistic Observation
- -More natural but problems with wait and observational
- - A research method where the subject(s) is(are) observed without interruption under normal or natural circumstances
-
Laboratory Observation
more control but more expensive, and less like the real world
-
Case Study
- -great detail
- -problems with generalizability
-
Surveys
-fast and cheap but can be affected by wording and context
-
Samples
Portion of the entire population used to estimate what is likely happening within a population
-
Populations
The entire group to which research is hoping to generalize (e.g., males, adults, U.S. citizens)
-
Confounds
Any variable that is not part of a research study but still has an effect on the research result
-
Sources of confounds
- 1. selection bias
- 2. the placebo effect
- 3. experimenter bias
confound: something that affects an experiment
-
Random Assignment
-The process of selecting participants for experimental and control groups by using a chance procedure to guarantee that each participant has an equal probability of being assigned to any of the groups: a control for selection bias
-
Placebos
A treatment condition used to control for the placebo effect where the treatment has no real effect on its own
-
Cause and effect relationships
-
True experiments
Research design that utilizes the most control over subjects and utilizes randomization
-
Correlation coefficients
The statistic or number representing the degree to which two or more variables are related. Often abbreviated 'r
-
The structure of the nueron
- -cell body
- -dendrites
- -axon
-
Communication between nuerons
- -information is carried out of the axon and through the den
- -nuerons differ in myelnation and diameter
- -communication is synaptic
- -sausage type is myelin sheath
- -insulates and speeds information
- -nuerons are not at rest-negative
-
Cerebellum
- -Preforms higher mental functions such as language and special outlines
- -(new brain)
-
Amygdala
-Emotion and aggressive behavior
-
Hippocampus

-
Cerebral Cortex
- Responsible for the higher mental processes such as language, memory and thinking
-
Somatosensory Cortex
- -orientation
- -plasticity means experience changes brain
- -there are gender differences
-
Phineas Gage
Was a railroad worker and had an iron pole put through his head, which caused severe psychological changes in him. The iron rod caused frontal lobe damage and severe personality changes. Was a nice guy but changed to rude and impulsive
-
Frontal Lobe (longest)
- -motor cortex- voluntary body movement
- -broca's area- speech production
- -frontal association area-judgement, personality,attention, abstract thoughts
-
Parietal Lobe (touch)

-
Temporal Lobe (auditory)
- -primary auditory cortex-where we hear
- -wernicke's area-speech reception
-
Plasticity
The ability of the brain, especially in our younger years to compensate for damage
-
Broca's Area vs. Wernicke's Area
- Broca's area: speech production
- Wernicke's area: speech reception
-
The primary visual cortex & what damage to one side does
- -the area at the end of the occipital lobes where vision is registered
- -if damage is done to one side, in both eyes they will have partial vision because each eye sends information to both the left and right occipital lobes

The Yerkes-Dodsen Law
-The principle that performance on tasks is best when the arousal level is appropriate to the difficulty of the task, high arousal for simpler tasks, moderate arousal for moderate tasks, and lower arousal for complex tasks
-
Components of motivation
- -social motives are learned
- -the need for achievement (nAch) is an internalized standard of excellence
- -high nAch choose difficult, attainable goals
- -work motivation can be increased by:

- 2.goal setting, difficult yet attainable
Activation
First steps required to achieve goal
Persistence
- Faithful and continued effort put forth in
- working toward a goal
Plan into action and stick with it
Intensity
- Refers to focused energy and attention applied in
- order to achieve the goal
-
Intrinsic vs. Extrinsic motivation
- Intrinsic: internal desire to preform a certain task
- Extrinsic: external source making a person want to do a task such as praise or money
-
Instincts
A behavior that is genetically programmed into an entire species. Thus, the behavior is not the result of learning, and can be seen across members of a species.
-
Drive-Reduction Theory
- Theory based on homeostasis and that there is an optimal level for everything
- A theory of motivation suggesting that biological
- needs create internal states of tension or arousal, called drives, which
- organisms are motivated to reduce

3 Components of emotion
- - Physical
- -Cognitive
- -Behavioral
-
Physical Emotion

-
Behavioral Emotion

-
Display Rules

- -Ex. faking a surprised face if you knew about a surprise party
-
James-Lange Theory

- that emotional feelings result when an individual becomes aware of a
- physiological response to an emotion-provoking stimulus
- b. Physical
- and behavioral causes of emotion
-
Cannon-Bard Theory
- -Emotion occurs simultaneousness
- a. Emotional-provoking
- stimulus is transmitted simultaneously to the cerebral cortex, providing the conscious mental experience of the sympathetic nervous system, causing the
- physiological arousal
-
Schachter-Singer Theory
- -Must have physiological and cognitive
- A 2 factor theory stating that for an emotion to occur. There must be:
- Physiological arousal
- A cognitive interpretation or explanation of
- arousal, allowing It to be labeled as a specific emotion
- b. Physiological
- and cognitive
-
Lazarus Theory
- -Cognitive comes first then physiological
- Cognitive appraisal is the first step in an emotional response and all other aspects of
- an emotion, including physiologically arousal, depend on it
- Cognitive comes first
-
The Facial Feedback Hypothesis
-Emotion is influenced by facial muscle feedback
-
The Polygraph

-
Measuring Stress ( SRRS )
-
Homes and Rahe’s measure of stress, which ranks
43 life events from most to least stressful and assigns a point value to each
- Score above a 300 – more likely to suffer a major
- health problem within the next 2 years
150-300 50% chance of becoming ill
Appropriate for adults in north America

3 Choice Related Conflicts
- 1. Approach-Approach
- 2. Avoidance-Avoidance
- 3. Approach-Avoidance
-
Approach-Approach

P.T.S.D
- -Post Traumatic Stress Disorder
- -Is a severe reaction to an extreme event
-
3 General Adaption Syndrome
- 1. Alarm Reaction
- 2. Stage of Resistance
- 3. Stage of Exhaustion
-
Alarm Reaction
- -The first stage you enter in a traumatic event
- -Ex. Stung by a bee on the arm, whole body goes into a panic
- -Person experiences a bursts of energy that aids
- in dealing with the stressful situation
-
Stage of Resistance
- -This is the stage where resistance is highest
- -The arm is now swollen from the bee sting, but your whole body is not harmed
- -When there are intense physiological efforts to
- either resist or adapt to the stressor
-
Stage of Exhaustion
- -The stage when your body goes back to a general alarm and the whole body is involved again
- - Which occurs if the organism fails in its efforts
- to the stressor
-
The Cognitive Theory of Stress
-Lazarus came up with the idea that it is not the stressor that causes stress, but how the person deals with it
-
Primary vs. Secondary Appraisal of Stress
- -Primary-Am I ok or in trouble? A cognitive evaluation of deciding if a situation is positive or negative
- -Secondary-Is this in my control? Using available resources and options to deal with stress
-
3 Coping Strategies
- 1. Problem Focused- Go to the source.
- -A direct response aimed at reducing modifying or
- eliminating a source of stress
- 2. Emotion Focused- Manage reaction, do yoga or meditation
