Biological Level of Analysis
  1. #1 Behavior can be innate because it is genetically based

    Annotations:

    • evolution plays a key role in behavior
    1. mirror neurons
      1. Gallese et al. 1996

        Annotations:

        • isolate neural response in rhesus monkeys reaching for food When another individual reached for food, the neural response was still seen in the monkeys even though they weren't reaching for food
      2. inheritance

        Annotations:

        • Genes and DNA are passed from parents to offspring
        1. twin studies
          1. Minnesota Twin Study - Bouchard et al. 1990

            Annotations:

            • Compared MZA's (monozygotic raised apart) and MZT's (monozygotic raised together) Cross-cultural validity - global study determines heritability estimate of 70% for intelligence
          2. intelligence
            1. Bouchard and McGue 1981

              Annotations:

              • Found that closer the kinship, the higher the correlation for IQ --- individuals 100% genetic relationship but different nurture = any IQ similarity will be genetics
          3. Darwin & natural selection
            1. hormones
              1. oxytocin

                Annotations:

                • creates bonding within families and society -- evolutionary strength in community
                1. adrenaline

                  Annotations:

                  • causes flight/fight response  -- evolutionary survival
                2. disgust
              2. #2 Animal research can provide insight into human behavior
                1. Martinez and Kesner 1991
                  1. humans share 93% of genes with rhesus monkeys
                    1. Gallese et al. 1996
                    2. #3 There are biological correlates of behavior
                      1. neurotransmission

                        Annotations:

                        • method by which messages are sent throughout the body --- cause body to respond to stimuli
                        • neuron - nerve cell axon - body of neuron neurotransmitters - cross synapses, stored in terminal buttons synapse - gab between neurons dendrites - receive information
                        1. acetylcholine

                          Annotations:

                          • muscle contraction

                            • Aim: determine role of acetylcholine in memory rats were trained to go through a maze, some given shots to block acetylcholine Findings: acetylcholine important role in creating memory of maze
                          2. dopamine

                            Annotations:

                            • voluntary movement, learning, and feelings of pleasure --- excess = schizophrenia
