The Scientific Method • Some key terms to know: • Hypothesis • Theory • Variable • Independent variable • Dependent variable • Operational definition • Placebo and expectancy effects
Statistics! • Statistics is the branch of mathematics involving the collection, description, and interpretation of numerical data • What is a normal distribution? • Be able to differentiate and calculate the: • Mean • Median • mode
What are Some Ways We Measure Behaviour? • Self-report measures • Reports by others • Often used to support self-reports • Physiological measures • Behavioural measures • All these approaches have their advantages and disadvantages
Methods Of Research • Descriptive research • Case studies • Naturalistic observations • surveys • Correlational research • Experimental research
Validity & Threats to Validity • Know the difference between: • Internal validity • External validity • Understand: • placebo effects • Confounding variables • Generalization • replication
Ethics in Research • Ethical guidelines for both: • Human research • Non-human animal research
The Neuron • Terms to know: • Neuron • Glia • Axon • Dendrite • Soma • Axon terminal • Nodes of ranvier • Myelin Sheath
Function of the Neuron • Know: • The primary purpose of the neuron • The stages of depolarization/repolarization • Action potential vs. resting potential • Threshold
Signal Transmission • Three types of neurons: motor, sensory, interneurons • 4 structure types: bipolar, unipolar, multipolar, pyramidal • What two ways can a response be terminated in the synapse? • Common NTs • Serotonin, dopamine, Ach, GABA norepinephrine • Know a small amount about each (in general are they inhibitory or excitatory?)
The Nervous System • Comprised of the central nervous system (CNS) and peripheral nervous system (PNS)
Brain Structures • Know major brain areas and their primary function • Hindbrain (medulla, pons, cerebellum) • Midbrain (reticular formation) • Forebrain (basal ganglia, thalamus, hypothalamus, cerebellum, lymbic system) • Cerebral Cortex (know Wenickes/Brocas areas)
Cortex • Prefrontal cortex • Association cortex • Agnosia • Split brain syndrome • Neural plasticity
Some Key Genetics Concepts • Nature or nurture? Or is it nature AND nurture? • Key genetics terms: • Genotype • Phenotype • Genes • Chromosomes • Allele • DNA
Gene Effects • Genes can be expressed in different ways • Dominant gene • Recessive gene • Polygenic transmission
Gene Technologies • Recombinant DNA procedures • Virus-mediated gene transfer • Transgenic mice
How Much is Genes and How Much is Environment? • Heritability coefficient • Twin studies • Compare concordance • Minnesota Twin Study • Adoption studies • Reaction range • Gene expression • epigenetics
Evolution and Behaviour • Evolution • Natural selection • Adaptation • Domain-specific adaptations • Genetic determinism • Social Darwinism
Evolutionary Psychology • What factors influence mate selection? • Parental investment • Different mating systems • Polygyny • Monogomous mating system • Polyandry • polygynandry
Helping Behaviour • Cooperation • Altruism • Kin-selection theory • Theory of reciprocal altruism • aggression
