Rutgers General Psychology Exam 1

Biological Neuroscientific - ✔How the body and brain enable emotions, memories, and sensory experiences. Example) Biological; cognitive, clinical Evolutionary - ✔Natural Science of Traits. How the natural selection of trains has promoted the survival of genes Example) Biological; developmental; social Behavior Genetics - ✔How our genes and our environment influence our individual differences Example) Personality; developmental; legal/forensic Psychoanalytic - ✔How behavior springs from unconscious drives and conflicts Example) Clinical; counseling; personality Behavioral - ✔How we learn observable responses Example) Clinical; Counseling; industrial-organizational Cognitive - ✔How we encode, process, store, and retrieve information Example) Cognitive neuroscience; clinical; counseling; industrial organization Social-Cultural - ✔How behavior and thinking vary across situations and cultures What contributions did Wundt, Titchener, and James make to psychology? -

✔Wilhelm Wundt- First Psychological Laboratory(1879) E.B Titchener- structuralism- the analysis of mental structures William James-Functionalism- the study of how the mind works What is introspection? - ✔Introspection: is the examination of one's conscious thoughts and feelings. What is structuralism? - ✔Structuralism: early school of thought promoted by Wundt and Titchener; used introspection to reveal the structure of the human mind. What is functionalism? - ✔Functionalism: early 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 What is hindsight bias? - ✔The tendency to believe, after learning an outcome, that one would have foreseen it. What is the scientific method? - ✔A design to study to test the hypothesis What is a hypothesis? - ✔A testable prediction, often implied by a theory What is an operational definition? - ✔Statement about the procedure the researcher used to measure a variable What is a case study? How is it limited? - ✔Descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles What is naturalistic observation? How is it limited? -

✔A descriptive technique of observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation What is the survey method? - ✔Survey Method: asking people questions about their thoughts, feelings, desires, and actions and recording their answers. What are wording effects? - ✔How the phrasing of question might affect people's expressed opinions. What is response bias? - ✔influence the response of participants away from an accurate or truthful response. What is random sampling? - ✔Everyone in the population has an equal chance of being studied What is the correlational method? - ✔a measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. What are positive and negative correlations? - ✔a statistical index of the relationship between two things from (-1.00 to +1.00) Does correlation indicate causation? What are the other alternatives? - ✔Positive Correlation: indicates a direct relationship, meaning that two things increase together or decrease together. For example) height and weight Negative Correlation: indicates an inverse relationship. As on thing increases, the other decreases. Example) hours of tv watched. Correlation does not indicate causation because correlations do not come with built in cause-effect arrows.

What is experimentation? What are IVs and DVs? What are experimental and control conditions? What is random assignment? What is the placebo effect? What is the expectancy effect? What are double-blind procedures? What is a confound? What is experimental control? - ✔Experimentation: researcher changes one variable in a controlled situation and observes the effects of that change on other aspects of the situation. Independent Variable: Manipulated by experimenter. Effect is being studied. Dependent Variable: Outcome Variable. Outcome that is measures Random Assignment- participants have an equal chance of being in every experiment group. Placebo Effect:caused by expectations alone; any effect on behavior caused by the administration of an inert substance or condition; which the recipient assumes is in active agent Expectancy Effect: a form of reactivity that occurs in scientific experiments or medical treatments when a research subject or patient expects a given result.

Double Blind Procedures: an experimental procedures in which both research participants and the research staff are ignorant about whether the research participants have received the treatment or a placebo. Cofound: A factor other than the factor being studied that might produce an effect Experimental Control: group not exposed to the treatment. What is generalizability? - ✔Of an outcome to other groups and settings What is replication? - ✔Repetition of a study. Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic findings can be reproduced. What are the mean, median, and mode? - ✔Mean-Average of all Scores Median-The middle Score Mode- Most frequently Occurring Score What is statistical significance? - ✔Probability that results are due to chance What are neurons? - ✔A nerve cell; the basic building block of the nervous system What are dendrites, the cell body, and axons? - ✔Dendrites: a neuron's often bushy, branching extensions that receive messages and conduct impulses toward the cell body

Cell Body: the spherical part of the neuron that contains the nucleus. It connects to the dendrites. Axons: the neuron extension that passes messages through its branches to other neurons or to muscles or glands What are glial cells? - ✔Cells in the nervous system that support, nourish, and protect neurons; they may also play a role in learning, thinking and memory. What is myelin sheath? - ✔A fatty tissue layer segmentally encasing the axons of some neurons; enable vastly greater transmission speed as neural impulses hop from one node to the next. What is the action potential - ✔Electrochemical impulse that travels from the cell body down to the end of the axon What is threshold? - ✔level of electric charge needed to stimulate action potential What is the all-or-none response? - ✔once the electric charge of the neuron reaches a certain threshold, it fires an action potential. What is a synapse? - ✔Junction between 2 neurons Impulses are transmitted across synapse via neurotransmitters. What are neurotransmitters? - ✔Chemical messengers that travel across synapse from one neuron to receptors on the next cell What is reuptake? -

✔Sending neuron reabsorbs excess neurotransmitters. What are inhibitory and excitatory signals? - ✔Inhibitory Signals: decrease likelihood that neuron will fire Excitatory Signals:increases likelihood that neuron will fire What are acetylcholine, endorphins, dopamine, serotonin, GABA, and epinephrine and norepinephrine? - ✔Acetylcholine: affects neurons involved in muscle action, learning, memory Endorphins: reduce pain and promote pleasure Dopamine: affects neurons involved in voluntary movement, reward, learning, memory Serotonin: affects neurons involved in sleep, appetite, mood GABA: inhibitory- calms Epinephrine: involved in stress response Norepinephrine: involved in stress response What are agonists and antagonists? - ✔Agonists: bind to receptors Antagonists: block to receptor What are motor neurons, sensory neurons, and interneurons? -

✔Motor Neurons: carry signals from brain or spinal cord to muscles, skin, and glands Sensory Neurons: carry messages from receptors to spinal cord and brain Interneurons: receives signals from sensory neurons and other interneurons and send impulses to other interneurons or motor neurons What is the central nervous system? - ✔the brain and spinal cord. Responds to sensory information. Sends messages to muscles, glands, organs What are reflexes? - ✔automatic responses that occur without any brain involvement. What is the peripheral nervous system? - ✔the sensory and motor neurons that connect the central nervous system to the rest of the body Somatic Nervous System - ✔the division of the peripheral nervous system that controls the body skeletal muscles. Autonomic Nervous System - ✔the part of the peripheral nervous system that controls the glands and the muscles of the internal organs. Sympathetic Nervous System - ✔The division of the autonomic nervous system that arouses the body, mobilizing its energy Parasympathetic Nervous System: - ✔The division of the autonomic nervous system that calms the body, conserving its energy
