goals of psychology ✔✔To accurately measure and describe, explain, predict, and control/alter
behavior and mental processes
William Wundt ✔✔first person to call himself a psychologist, opened first psych lab in Germany
(Univ of Leipzig), called his approach Structuralism. He looked inward on experiences and how
they related to one another.
William James ✔✔American, influenced by Darwin, FUNCTIONALISM, interested in the
adaptive functions served by behavior and thought, not a question of whether we smell or not,
but what it does for us, more practical, also first classroom teacher of psychology (Darwinism-

John Watson ✔✔Championed psychology as the science of behavior and demonstrated conditioned responses on a baby, behaviorist (science rooted in observation)

B.F. Skinner ✔✔Behaviorist, he rejected introspection and studied how consequences shape behavior.

Sigmund Freud ✔✔emphasized the ways emotional responses to childhood experiences and our unconscious thought processes affect our behavior, thus psychology till the 1920's was defined as the "the science of mental life"

Neuro-biological/Physiological ✔✔behavioral and mental processes are ultimately explained by the activities of the nervous system, especially the brain, and the action of hormones, neurotransmitters and other chemicals

psychodynamic ✔✔how behavior springs from unconscious drives and conflicts

Horney, Erikson, Freud (psychoanalytic) ✔✔*behavior and mental processes are largely determined by unconscious mental and emotional conflicts. Usually put instincts or desires for sex, aggression, security, and power against environmental obstacles to fulfillment of those desires,

Behavioral ✔✔Psychology can be studied scientifically by examining the overt behavior of humans and animals. Behavior is largely shaped by the patterns & punishments that each person has experienced in his/her environment

Cognitive ✔✔Behavior is determined by how information is encoded, stored, retrieved, or otherwise processed by the brain

Humanistic ✔✔historically significant perspective that emphasized the growth potential of healthy people and the individual's potential for personal growth. Humans make choices by thinking, rather than by simple influence from the environment

biopsychosocial model ✔✔the integrated viewpoint that incorporates various levels of analysis and offers a more complete picture of any given behavior or mental process

Hindsight bias ✔✔The feeling that 'I knew it all along' and you feel confident after you hear the results, that you would have been able to foresee it

Overconfidence ✔✔Similar to hindsight bias. Once you find out the answer, hindsight makes it seem obvious and you become overconfident.

Steps in Scientific Method ✔✔Identify a question of interest from experience, the literature, or theory

Pose a testable hypothesis (define hypothesis)

Conduct a study to test hypothesis

Descriptive Methods ✔✔Benefits; lets us observe and describe things in everyday life. Drawbacks; can not change factors and data can be misrepresented. Does not explain behavior but describes it. No control of variables. Can be used to generate hypotheses

Correlational ✔✔Benefits; helps us figure out how closely two things vary together and helps us predict. Drawback; correlation indicates the possibility of a cause-effect relationship, but it does not prove causation.

Experimental ✔✔Benefits: Can draw cause and effect infererences. Manipulate one or more factors in the experiment and control other variables. Must have control group. Drawbacks; Not ethical to manipulate certain variables, and may not generalize to other contexts.

Random Assignment ✔✔By random assignment of participants, the experimenter aims to control other relevant factors. Random assignment is the assigning of participants to experimental and

Operational Definition ✔✔statement of procedures (operations) used to define research variables, select research method, collect and analyze data, interpret and publish results.

Experiment ✔✔an organized way to prove or disprove a hypothesis derived from observations.

Be able to identify the IV and DV if presented a study example.

Function of Nervous system ✔✔To allow rapid, specific communication throughout the body

Neuron ✔✔a nerve cell; the basic building block of the nervous system

Axon ✔✔also known as a nerve fiber; conducts electrical impulses away from the neuron's cell body; "Axon's Announce"--are cell's transmitter

Dendrite ✔✔Multiple, usually shorter fibers which receive signals from the axons of other neurons, are cells "receivers"

Myelin sheath ✔✔a fatty substance that insulates the axon from other neurons, makes nerve conduction- faster

Terminal branches ✔✔form junctions with other cells

Terminal buttons ✔✔area at the end of an axon fiber which holds inside of it small sacks called synaptic vesicles

Cell body/Soma ✔✔The largest part of a cell, the cell body holds all of the general parts of a cell as well as the nucleus and supports the entire neuron.

Vesicle ✔✔sacs of neurotransmitters at the terminal buttons of axons

Neural impulse ✔✔electrical discharge that travels along a nerve fiber

Threshold ✔✔the level of stimulation required to "fire" a neuron.

Action potential ✔✔a neural impulse; a brief electrical charge that travels down an axon.

MRI- "magnetic resonance imaging" ✔✔- technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. Shows brain function

fMRI- "functional magnetic resonance imaging ✔✔technique for revealing blood flow and, therefore, brain activity by comparing successive MRI scans. Shows brain function.

Brainstem ✔✔oldest part of the brain, beginning where the spinal cord swells and enters the skull.

Medulla ✔✔base of the brain stem that controls heartbeat and breathing

Reticular formation ✔✔- a nerve network in the brainstem that plays an important role in controlling arousal.

Thalamus ✔✔the brain's sensory switchboard, directs messages to the sensory areas in the cortex and transmits replies to the cerebellum and medulla.

Cerebellum ✔✔the "little brain" attached to the rear of the brainstem. Helps coordinate voluntary movements and balance

Limbic system ✔✔A doughnut shaped system of neural structures at border of brainstem and cerebrum, associated with emotions such as fear, aggression, and drives for food and sex. Includes the hippocampus, amygdala, and hypothalamus.

Amygdala ✔✔consists of two lima bean-sized neural clusters linked to the emotions of fear/anger.

Hypothalamus ✔✔lies below the thalamus and directs several maintenance activities like eating, drinking, body temperature, and control of the emotions. Helps govern the endocrine system via the pituitary gland. helps keep body in homeostasis.

Hippocampus ✔✔processes conscious memories.

Frontal lobes ✔✔portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgements.

Corpus callosum ✔✔the large band of neural fibers that connects the two brain hemispheres and carries messages between them

Split-brain ✔✔a condition resulting from surgery that isolates the brain's two hemispheres by cutting the fibers (mainly those of the corpus callosum) connecting them.

Neural plasticity ✔✔the brain's ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience

Neurosurgery ✔✔The medical specialty concerned with prevention, diagnosis, treatment and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nerves, and extra-cranial cerebrovascular system.

Central Nervous system ✔✔Consists of the brain and spinal

Peripheral Nervous System ✔✔Consists of all other neurons

Somatic nervous system ✔✔enables voluntary control of our skeletal muscles

Autonomic nervous system ✔✔controls our glands and the muscles of our internal organs

Right hemisphere ✔✔o Regulation of negative emotion

o Responses to simple commands

o Memory for shapes and music

o Recognition of faces

o Interpreting spatial relationships and visual images

Normal waking consciousness: Stage 2 ✔✔During early, light sleep the brain enters a low- amplitude, regular wave form called theta waves (5-8cps).

Normal waking consciousness: Stage 3-4 ✔✔During deepest sleep, brain activity slows down. There are large-amplitude, slow delta waves (1.5-4cps). High and low waves.

Alpha waves ✔✔the relatively slow brain waves of a relaxed, awake state (9-14cps)

Delta waves ✔✔The brain emits large, slow delta waves first, in stage three, then four. brain waves associated with deep sleep (1.5-4cps)
