The scientific study of the biology ofbehavior Also called psychobiology,behavioral biology, behavioralneuroscience Psychology: the scientific study ofbehavior`Copyright 2009 Allyn & BaconBiopsychology and OtherDisciplines of Neuroscience Knowledge from other disciplines ofneuroscience is applied to the study ofbehavior Each discipline studies a differentaspect of the nervous system thatinforms our understanding of whatproduces and controls behaviorCopyright 2009 Allyn & BaconOther Disciplines ofNeuroscience Neuroanatomy Structure of the nervous system Neurochemistry Chemical bases of neural activity Neuroendocrinology Interactions between the nervous systemand the endocrine systemCopyright 2009 Allyn & BaconOther Disciplines ofNeuroscience (continued) Neuropathology Nervous system disorders Neuropharmacology Effects of drugs on neural activity Neurophysiology Functions and activities of the nervoussystemCopyright 2009 Allyn & BaconBiopsychological Research:Three Major Dimensions Human and nonhumansubjects Experiments andnonexperiments Pure and applied researchCopyright 2009 Allyn & BaconHuman and NonhumanSubjects While some questions about behaviorcan only be addressed using humansubjects, much can be learned fromstudying the brains of other species Species differences are morequantitative than qualitativeCopyright 2009 Allyn & BaconHuman and NonhumanSubjects (continued) Why use nonhumans? Simpler brains makes it more likely that brain-behaviorinteractions will be revealed Comparative approach gain insight by makingcomparisons with other species Fewer ethical restrictions than with humans Why use humans? They can follow instructions They can report their introspections Theyre cheaperCopyright 2009 Allyn & BaconExperiments andNonexperiments Experiments involve the manipulation ofvariables In nonexperiments, the researcher doesnot control the variables of interest Quasiexperimental studies Case studiesCopyright 2009 Allyn & BaconPure and Applied Research Pure research conducted for thepurpose of acquiring knowledge Applied research intended to bringabout some direct benefit to humankind Some research projects may haveelements of bothCopyright 2009 Allyn & BaconDivisions of Biopsychology Six major divisions Physiological psychology Psychopharmacology Neuropsychology Psychophysiology Cognitive neuroscience Comparative psychology Each has a different approach, but there ismuch overlapCopyright 2009 Allyn & BaconCopyright 2009 Allyn & Bacon` There is a tendency to think in simpledichotomies when explaining behavior: Is it physiological or psychological? Is it inherited or is it learned? Both questions are common, yetmisguidedFrom Dichotomies toRelations and InteractionsCopyright 2009 Allyn & Bacon Cartesian dualism: Descartes arguedthat the universe consists of twoelements Physical matter Human mind (soul, self, or spirit) Cartesian dualism views the mind andbrain as separate entitiesIs It Physiological orPsychological?Copyright 2009 Allyn & BaconIs It Inherited or Is It Learned? The nature-nurture issue Watson, father of behaviorism, believedthat all behavior was the product oflearning (nurture) Ethology, the study of animal behaviorin the wild, focused on instinctivebehaviors, emphasizing natureCopyright 2009 Allyn & Bacon Problem 1: Brain damagehas an impact on psycho-logical functioningOliverSackss case study of aman with asomatognosia Deficiency in awareness ofparts of ones own body Due to damage to the rightparietal lobeProblems of Traditional Dicho-tomies: Mind-Brain DualismCopyright 2009 Allyn & Bacon Problem 2: Chimps show psycho-logical (i.e., human) abilitiesGallups research on chimp self-awareness Chimps spontaneously groom themselvesin mirror Chimps examine and touch red mark ontheir own face seen in mirrorProblems of Traditional Dichotomies: Mind-Brain DualismCopyright 2009 Allyn & Bacon Many factors have an impact on behavior otherthan genetics (nature) or learning (nurture) Nurture now encompasses learning andenvironment While it is generally accepted that behavior is aproduct of nature and nurture, many still ask howmuch is determined by each, but genetic andexperiential factors do not merely combine in anadditive fashionProblems of TraditionalDichotomies: Nature-or-Nurture
