What is Psychology?
|
Scientific study of behavior and mental processes.
|
|
Difference between Scientific Psychology and Everyday Psychology.
|
Scientific: Laws of Behavior, Deterministic, Tentative Explinations,controlled studies, Explination refer to people in general.
Everyday: Bizarre unusual behavior, free will, nonfalsifiable, no studies, explations focus on specific examples. |
|
What are the three major philosophical influences on Psychology.
|
Mechanism, Empiricism, and Positivism
|
|
What is Mechanism
|
Belief that all behavior follows all natural processes
|
|
What is Empiricism
|
persuit of knowledge through observing nature and experimentations ( All Learning, All Knowledge is based on experience)
|
|
What is Positivism
|
Belief only things objectivly observable should be studied, and excepted as turth
|
|
Who was Wilhelm Wundt
|
(1843-1920) credited as founder of psychology; introspection.
|
|
Edward Titchener & Margaret Floy Washburn
|
(1867-1927) Structralisim-study of conciousness by introspection
|
|
Who was Clever Hans
|
German horse; Experimental approach to animal behavior (Early 1900'S).
|
|
Who was Ivan Pavlov
|
Co-Discoverer of classical conditioning (1849-1936)
|
|
Who was William James
|
(1842-1910) functionalism; first American psychologist.
|
|
Who was Sigmund Freud
|
(1856-1939) Psychoanalysis; sexual analysis - unconcious drives (sex drives)
|
|
Who was John Watson
|
(1878-1958) founder of behaviorism, classical conditioning,
|
|
Who was B.F. Skinner
|
1904-1990 radical behaviorism operant conditioning-visionary
|
|
World War 11
|
needed to treat war victims
|
|
Who was Carl Rogers
|
1902-1987 humanistic psychology feelings
|
|
What is Cognative Revolution
|
(Neisser 1967) Study of thoughts
|
|
What is a True Experiment
|
manipulate certain events and observe the effects on the other events while controlling for confounds.
|
|
What is Random Selection
|
Draw randomly from population of intrest for inclusion in study
|
|
What is Random Assignment
|
make groups equal by dispersing confounds
|
|
Pros of Experimental Studies
|
Allows strongest casual conclusion due to good internal and external validity
|
|
Cons of Experimental Studies
|
External Validity problems due to artificiality; reactivity may also be a problem.
|
|
What are the measures of central tendency used in Psychology
|
Mean-Average
Median-Half Point Mode- Most frequent |
|
What are the measures of variablity used in Psychology
|
Range- Diff. highest & lowest
Standard Deviation- Measures of spread or scores |
|
What are the methods of studying the brain structure and function
|
Lesion Studies, X-rays, Computerized Axial Tomography (CAT), Positron Emission Tomography (PET),
Electroencephalogram (EEG) |
|
Lesion Studies
|
Patients who have suffered damage to a brain a brain structure (PHINEAS GAGE 1848)
|
|
X-rays
|
only reveal major structural damage
|
|
CAT
|
series of X-rays to reveal 3 dimentional brain structure
|
|
PET
|
providies functional info; able to observe which part of the barain are active during certain activities
|
|
EEG
|
provides electrical functioning information; non invasive
|
|
Magnetic Resomance Imaging (MRT)
|
provides structural and functional infomation less exposure for patients.
|
|
What are the Function of a Neuron Axonal Transmission
|
Microelectrodes,Resting Potential, Threshold, Action Potential, The All or non principal
|
|
Microroelectrodes
|
measures of electrical impluses
|
|
Resting Potential
|
neuron "at rest" inside is negatively charged (-70mv) Relative to the outside.
|
|
Threshold
|
Vaue at which an action potential will occur (-55mv)
|
|
Action Potential
|
lasts one millsecond; electrical impluses travels down axon and reaches terminal ending
|
|
"All or None" Principal
|
only applies to axonal transmission
1.Once threshold is reached axonal flip 2. Very intensive stimulus may trigger more neurons to fire. |
|
What are the function of a neuron; Synaptic Transmission
|
Presynaptic mambrane, Synapse, Postsynaptic membrane, Re-Uptake and enzyme breakdown of neurotransmitters.
|
|
Presynaptic Membrane
|
(terminal ending) contains vessicles with neutransmitters (chemicals that influence other neurons).
|
|
Synapse
|
gap between terminal ending and dendrite of next neuron
|
|
Postsynaptic Membrane
|
receptor cells for neutrotransmitters
|
|
Lock and key theory
|
NT only affects postsynaptic membrane if shape fit into certain receptor molecules
|
|
Re-Uptake & Enzyme breakdown
|
jhdkhs
|
|
What are the two types of Medications that Work
|
Agonists and Antagonists
|
|
What is Agonists
|
increase effectiveness of a NT (e.g. block re-uptake, mimic NT at receptor cells block enzyme breakdown,
|
|
What Antagonists
|
decrease effectiveness of NT
|
|
What are the two parts of the Nervous System
|
Central Nervous System (CNS; brain and spinal cord)
Peripheral Nervous system |
|
What are the functions of the Peripheral Nervous System
|
Somatic (controls skeletal, voluntary muscles and sense organs)
Autonomic(controls heart, Lungs, Digestive System, etc) |
|
What are the two functions associated with Autonomic PNS
|
Sympathetic (produces Arousal)
Parasympathetic(decreases Arousal) |
|
What are the three main Brain Structures
|
Hindbrain, Midbrain, and Forebrain
|
|
Hindbrain
|
Medulla(controls heartbeat, blood circulation, breathing, Vomiting, Caughing,etc)
Cerebellum (controls Balance and muscle coordination) Pons (relay station linking Hindbrain to the rest of the brain; involved with sleeping and walking) |
|
Midbrain
|
Reticular Activating system (relay station and filtering device; involved with arousal and waking
|
|
Forebrain
|
Limbic System (involved with emotions and memory)
A. Amygdala (turns on aggression when stimulated) B. Spectum (turns off aggression with stimulated) C. Hippocampus (memory) D.Cingulate Gyrus (pleasure after eating or sex) Hypothalamus (homeostasis; controls pituitary; sex sleep; hunger; thirst) Thalamus (Relay Station) located above the hypothalamus;organization center) Cerebral Cortex (right and left hemispheres ; corpus callosum) A. Frontal lobe (personality; and advanced thinking) B. Temporal lobe (auditory cortex) C. Parietal lobe (sensory cortex) D. Occipital lobe (vision) |
|
Endocrine System
|
A. Hormones (chemicals that travel in bloodstream; serve similar function as NT)
B. Key Glands and Hormones 1.Adrenal gland (on top of kidneys; release hormone adrenalin; control body's response to stress and danger) 2.Pituitary Glands(at base of brain; controlled by hypothalamus; controls release of hormones from many other important glands, such as the thyroid, overies, and testes) 3.Pheromones (hormones that mark territories and singal desire to mate in many species; unclear if they contribute to human behavior) |
