4 Goals of Psychology |
Description, Explanation, Prediction, Influence (Control) |
|
2 Types of Research that you must define before testing |
Basic/pure: answers a questions Applied Research: looking to change or fix a problem |
|
Critical thinking |
Independent thinking, suspension of judgement, willing to modify or abandon previous judgements |
|
Experimental method |
Research designed to test a hypothesis |
|
Correlation method |
Used to determine the relationship between characteristics, behavior, or events |
|
Descriptive Research Methods |
Naturalistic/Laboratory Observation Case Study Method Survey Research |
|
Naturalistic Observation |
Researchers record behavior that they observe in the subjects natural setting without influencing behavior |
|
Laboratory Observation |
Study behavior in a lab setting |
|
Case Study Method |
One person or a small group is closely studied over a long period over a long period of time |
|
Survey research |
Interviews or questions about attidutes, experiences, or behavior |
|
Representative sample |
Random, includes all diversities, also called a mini-population |
|
Biased sample |
handpicked sample to prove your point or hypothesis |
|
Experimental Method |
Research designed to test a hypothesis |
|
Hypothesis |
Testable prediction about when a behavior or mental process will occur |
|
Variable |
Element, feature, or factor that is liable to vary or change |
|
Independent Variable |
The factor that is manipulated; the variable whose effect is being studied |
|
Dependent Variable |
the outcome that is measured; the variable that may change when the independent variable is manipulated |
|
Experimental group |
in an experiment, the group exposed to the treatment; or to one version of the independent variable |
|
Control group |
The group not exposed to the treatments; contrasts with the experimental group and serves as a comparison for evaluating the effect of the treatment |
|
Confounding variables |
Something you didn't take into account when starting experiment |
|
Selection bias |
Choose the people instead of random individuals |
|
The placebo effect |
the belief that their placebo will work is so strong that they get better |
|
Experimenter bias |
The experimenter sees what they want to see because they want it to work |
|
Double blind technique |
Neither the researcher nor the clients know which group is receiving the placebo |
|
the correlation method |
determines the relationship between characteristics, behavior, or events |
|
Reliable |
the extent to which a test yields consistent results, as assessed by the consistency of scores on two halves of the test, on alternative forms of the test, or on retesting |
|
Valid |
the extent to which a test measures what it is supposed to measure |
|
Structuralism |
early school of thought promoted by Wundt and Titchener; used introspection to reveal the structure of the human mind; pure sensations combine to form perceptions |
|
Functionalism |
How humans use mental processes to adapt to their environment; school of thought promoted by James and influenced by Darwin; explored how mental and behavioral processes function- how they enable the organism to adapt, survive, and flourish |
|
Behaviorism |
Something in your environment is influencing your behavior; evaluate your actions; immediate environment |
|
Psychoanalysis |
Idea that our driving forces are our subconscious sexual and aggressive urges by Freud; mind is like an iceberg |
|
Humanistic psychology |
We have free will and the ability to change; we will always try to better ourselves and problems arise when we cannot; i.e. problems= mental illness |
|
Cognitive psychology |
The study of mental processes such as attention, language use, memory, perception, problem solving, creativity, and thinking |

5 phenomena |
|
Neuron |
Specialized cells that conduct impulses through the nervous system |
|
Cell body |
Nucleus-containing central part of a neuron excluding axons and dendrites |
|
Axon |
long threadlike part of a nerve cell along which impluses are conducted from cell to cell |
|
Myelin sheath |
insulating covering on an axon between the the nodes of ranvier |
|
Dendrites |
where impulses are received from other cells at synapses are transmitted to the cell body |
|
Synapse |
From an axon terminal to synaptic vesicles; into neurotransmitters that cross the synaptic cleft into receptor sites on opposite neuron, take in the best fitting neurotransmitter |
|
Neurotransmitters |
Chemicals that transmit messages across synapses; stored in synaptic vesicles in the axon terminal; are replaced by manufacturing, recycling, and reuptake |
|
Nodes of Ranvier |
Gap in myelin sheath on an axon |
|
Receptor |
Responds specifically to a particular neurotransmitter, hormone, antigen, or other substance |
|
Nervous system |
CNS and Peripheral Peripheral splits into Somatic and Autonomic Autonomic splits into Sympathetic and Parasympathetic |
|
Central Nervous System |
Brain and the Spinal Cord |
|
Peripheral Nervous System |
Nervous system outside CNS; consists of somatic and autonomic |
|
Somatic |
Part of the peripheral associated with skeletal muscle and voluntary control of body movements |
|
Autonomic |
Part of peripheral responsible for unconsciously directed function (breathing, heartbeat, and digestive processes) |
|
Sympathetic |
Fight or flight; part of autonomic system that increases heartbeat, dilates pupils; the 'arousing system' |
|
Parasympathetic |
Part of autonomic system that slows heartbeat, contracts pupils, the 'calming system' |
|
Spinal Cord |
Cylindrical bundle of nerve fibers and associated tissues that is enclosed in the spine and connects are nearly all parts of the body to the brain, forming the CNS |
|
Endocrine system |
Ductless glands that produce and secrete hormones |
|
Hormones |
Chemicals manufactured in one part of the body that affect another part |
|

Genes |
Provide all info about cells' purpose; determine the transmission of inherited traits |
|
Dominant Gene |

|
Recessive Gene |
Need both to show through and be present |
|
Polygenic |
Traits involving several genes; usually not recessive or dominant |
|

|
Encoding |
Transforming information so it can be stored |
|
Storage |
Putting the information in the memory |
|
Consolidation |
the transfer of information from short-term into long-term memory |
|
Retrieval |
Act of getting the information out of our memory |
|
The three memory systems |
Sensory, Short-term, Long-term |
|
Sensory Memory |
Everything we see, hear, feel, sense Visual lasts a fraction of a second (iconic memory) Auditory lasts about 2 seconds (echoic memory) |
|
Short-Term Memory |
Also called working memory Can hold about 7 items Lost in 30 seconds without rehearsal |
|
Long-Term Memory |
Where data can be stored for long periods of time, indefinitely Two Types: Declarative and Non-declarative |
|
Declarative Memory |
(Explicit) Refers to memories that can be consciously recalled (facts & verbal knowledge) Falls into episodic and semantic memory |
|
Episodic Memory |
Memory of autobiographical events; contextual who, what, when, where, why knowledge; collection of past experiences from a particular time and place |
|
Semantic Memory |
Memory of general world knowledge that has accumulated throughout life |
|
Non-declarative Memory |
(Implicit memory) Doesn't require conscious thought; like riding a bike or reading |
|
Displacement |
Getting rid of or moving to long term memory |
|
Chunking |
Organizing items into familiar, manageable units; often occurs automatically |
|
Rehearsal |
Repeating something over and over again |
|
Elaborative rehearsal |
Repeating it over and over again and relating it to something in your life |
|
Levels of processing mode |
by Craig and Lockhart; describes memory recall of stimuli as a function of the depth of mental processing. Deeper levels on analysis produce more elaborate, longer lasting, and stronger memory traces that shallow levels of analysis; 1. Shallow 2. Intermediate 3. Deep |
|
Three kinds of memory tasks |
Recall, Recognition, Relearning |
|
Recall |
Recalling without retrieval cues; serial- the 50 state; free- items from a picture |
|
Recognition |
A sense of familiarity when encountering people, events, or objects that have been previously encountered |
|
Relearning |
Regaining knowledge of material previously learned and forgotten |
|
Serial position effect |
Phenomenon in which faster learning and recall of items occur at the beginning and end in comparison to items at the middle of a list |
|
Primacy effect |
Remember what was first, now in long term memory |
|
Recency effect |
Remember what was last, still in short term memory |
|
State-dependent memory effect |
Easier to remember when you are in the same mood or emotional state |
|
Causes of forgetting |
Encoding, Decay theory, Interference |
|
Encoding failure |
Don't make an effort to remember |
|
Decay theory |
Proposes that memory fades due to the passage of time; as time passes memory retrieval and memory strength wear away |
|
Retroactive interference |
Most recent occurrence interferes with long term memory |
|
Proactive interference |
Tendency of previously learned material to hinder recent learning |
|
Retrograde amnesia |
Loss of memory-access to events or information from before the amnesia-causing event |
|
Ways to improve memory (6) |
Over learning, massed practice, rhyme, method of loci, first letter technique, peg word |
|
Overlearning |
to continue studying or practicing after initial proficiency as to reinforce or ingrain the material or skill |
|
Massed practice |
Practice that occurs without rest between trials (cramming) |
|
Rhyme |
Creating a rhyme to remember something |
|
Method of loci |
Also called the memory palace, assigning things to different objects, and 'walking' through your 'palace' allows you to remember this information |
|
First letter technique |
ex: ROY G BIV using first letters to create an acronym |
|
