BIOLOGICAL APPROACH

UNDERSTAND BEHAVIOUR LOOK BIOLOGICAL STRUCTURE PROCESSES WITHIN BODY E.G. NEUROCHEMISTRY

UNDERSTANDING BRAIN FUNCTION EXPLAIN THOUGHTS AND BEHAVIOUR

MIND LIVES BRAIN - THOUGHTS FEELINGS HAVE PHYSICAL BASIS

CONTRAST COGNITIVE APPROACH

STUDY CHARACTERISTICS - INTELLIGENCE SAME WAY PHYSICAL CHARACTERISTICS - HEIGHT

TWIN STUDIES DETERMINE LIKELYHOOD TRAITS GENETIC BASIS COMPARING CONCORDANCE RATES

IDENTICAL (MONOZYGOTIC) HIGER CONCORDANCE NON IDENTICAL (DIZYGOTIC) SCHIZOPHRENIA - GENETIC BASIS

MZ TWINS SHARE 100% GENES

GENOTYPE GENETIC MAKEUP

PHENOTYPE WAY GENES EXPRESSED CHARACTERISTICS 

GENOTYPE INEVITABLY INFLUENCED ENVIORMENTAL FACTORS

SAME PHENOTYPES EXPRESSED DIFFERNTLY

ILLUSTRATES BEHAVIOUR DEPENDS INTERACTION INHERITED FACTORS & ENVIORNMENT

CHARLES DARWIN - NATURAL SELECTION

GENETICALLY DETERMINED BEHAVIOUR ENHANCE SURVIVAL CONTINUE FUTURE GENERATIONS

OCCURS NATURALLY

INDIVIDUAL SURVIVES NOT REPRODUCE TRAITS EXIT GENE POOL

PRECISE HIGHLY SCIENTIFIC METHODS

TWIN STUDIES - DRUG TRIALS

ADVANCE TECHNOLOGY ACCURATE MEASURE BIO AND NERUAL PROCESSES

BASED RELIABLE DATA

INCREASED UNDERSTANDING DEVELOPMENT PSYCHOACTIVE DRUGS - TREAT MENTAL ILLNESS

NOT EFFECTIVE ALL PATIENTS

STRENGTH: SUFFER MANAGE CONDITION NORMAL LIFE

EXPLAIN MENTAL ILLNESS - NEUROTRANSMITTERS

EVIDENCE - PARTICULAR DRUG REDUCES SYMPTOMS ASSUME NEUROCHEMICAL IN DRUG CAUSES DISORDER

ASSOCIATION BETWEEN 2 FACTORS DOESNT MEAN ONE IS CAUSE

BIO APPROACH CLAIMING DISCOVERED CAUSES ONLY ASSOCIATED
