What's Inside: Foundations of Psychology: 4 Definitions of Psychology (Science of Mind & Behavior, Experimental Epistemology, Knowing & Experiencing, Things that Move) Wilhelm Wundt (1879 Leipzig – first psychology lab, separated psychology from philosophy) John Broadus Watson (1913 – behaviorism, only observable science) Ulric Neisser (1967 – Cognitive Psychology textbook) James Gibson ( – locomotion as basic problem for psychology) Philosophical Roots: Rationalism/Nativism – born with innate ideas Empiricism/Associationism – born as clean slate, experience as knowledge source Mind-Body Problem – Dualism vs. Materialism Descartes & the Reflex Concept – every action is direct response to external event Biological Psychology & Neuroanatomy: Central Nervous System (brain & spinal cord) vs. Peripheral Nervous System (efferent/afferent nerves, somatic division, autonomic nervous system) Sympathetic (revs up) vs. Parasympathetic (restores) branches Hindbrain (medulla – breathing/circulation; pons – attentiveness/sleep; cerebellum – coordination) Midbrain (eye movement, sensory relay) Forebrain (cortex – 80% of human brain, 3mm thick) Thalamus (sensory relay station), Hypothalamus (motivated behaviors: eating, drinking, sex) Limbic System (hippocampus – memory; amygdala – emotion) Corpus Callosum (connects hemispheres) Brain Damage Syndromes (Exam Focus): Apraxia – lesions in frontal lobe, voluntary action disturbance Agnosia – cannot identify objects via affected sensory modality (prosopagnosia – face blindness) Aphasias – Broca's area (non-fluent) vs. Wernicke's area (fluent) Neglect Syndrome – right parietal lobe damage, left side neglect Split-Brain Patients – left hemisphere (language, inferences) vs. right hemisphere (facial recognition, spatial relations) Phineas Gage – prefrontal area damage, response inhibition deficiency The Neuron: Dendrites, cell body (soma), axon Motoneurons, sensory neurons, glia (10:1 glia-to-neuron ratio) Nodes of Ranvier – speed nerve impulses White Matter (myelinated axons) vs. Gray Matter (cell bodies, dendrites) Resting Potential (-70 mV), Excitation Threshold (-55 mV), Action Potential All-or-None Law – same amplitude regardless of stimulus Temporal Summation vs. Spatial Summation Neurotransmitters – Acetylcholine (ACh), GABA, Norepinephrine (NE), Dopamine (DA) Agonists (enhance) vs. Antagonists (impede) Learning & Conditioning: Classical Conditioning – UCS, UCR, CS, CR Pavlov – equipotentiality principle, inhibition vs. excitation, spontaneous recovery Experimental extinction – repeated CS without UCS Stimulus generalization gradient Partial reinforcement – harder to extinguish Schedules of Reinforcement – fixed interval, variable interval, fixed ratio, variable ratio (highest response rates) Instrumental Conditioning – reinforcement depends on organism making proper response Shaping by successive approximations – novel behaviors, complex chains Garcia Effect (learned taste aversion) – CS and UCS separated by hours, built-in readiness Second-order conditioning Contingency – evident in 2-month-old infants Memory: Short-Term Memory – acoustic/speech coding, ~7 items, displacement forgetting Long-Term Memory – unlimited capacity, semantic coding, permanent, misplacement forgetting Implicit Memory (no awareness of remembering) vs. Explicit Memory Procedural Memories – can be established in Korsakoff's patients Semantic Memory – permastore (little change over decades) Proactive Interference – old phone number interferes with new Maintenance rehearsal – possible in anterograde amnesiac H.M. Chunking – recoding items into larger chunks Recency effect – abolished if recall delayed 30 seconds with rehearsal prevented Encoding-specificity hypothesis – similarity between learning and recall conditions Hippocampus damage – similar to Korsakoff's syndrome Retrograde amnesia – young traces more vulnerable than old traces Spreading activation hypothesis – similar concepts near each other in semantic network Alzheimer's disease – degeneration of front part of brain and hippocampus Sensation & Perception: Psychophysics – laws relating sensation changes to energy variables Weber fraction – smaller for vision than taste (vision more sensitive) Just-Noticeable Difference (JND) Distal stimulus (the actual object) vs. Proximal stimulus Doctrine of Specific Nerve Energies – ear connected to optic nerve = visual experience Empiricism – all knowledge comes through senses Gestalt Theory – whole is different from sum of parts (closure, subjective contours) Trichromatic Theory (Young & Helmholtz) – difficulty explaining yellow and opponent pairs Opponent-Process Theory – red-green and blue-yellow opposing pairs Rods & Cones – rods (cylindrical, scotopic), cones (conical, photopic, fovea concentration) Color blindness – most common in males, red-green confusion most frequent Gibson's Ecological Approach – direct perception, higher-order patterns, texture gradients, optic flow field, time-to-contact (tau) Helmholtz – unconscious inference, best inference, monocular depth cues Monocular Cues – interposition, linear perspective, texture gradients Brightness contrast – adjacent visual cells mutually inhibitory Physiology & Temperature Regulation: Endotherms (stable body temperature) vs. Ectotherms (variable) Vasodilation vs. Vasoconstriction Key Experiments & Phenomena: Amygdala vs. Hippocampus damage – fear response without recall vs. recall without fear Phrenology (Franz Joseph Gall) – brain as material instrument, mental faculties localized Lashley – memory preserved with minimal cortex remaining Sechenov – all behavior understood as reflex actions Updated for Spring 2026, this guide mirrors Professor Lundquist's PSYC 1100 Exam 1 format with 100% correct solutions.
