Study Notes
Biological Psychology
- Focuses on the physiological, evolutionary, and developmental mechanisms of behavior and experience
- Emphasizes the study of brain areas and sub-areas
- Brain function depends on communication among neurons
- Neuron activity produces behavior and experience
Biological Explanations of Behavior
- Physiological: Links behavior to brain and organ activity (e.g., area of brain enabling bird song)
- Ontogenetic: Describes behavior development (e.g., the combined role of genes and environment in bird song)
- Evolutionary: Examines a behavior's evolutionary history (e.g., similar songs in bird species with a common ancestor)
- Functional: Explains why a behavior or structure evolved (e.g., singing improves mating success)
Mind-Body Problem
- Dualism: Mind and body are distinct substances that interact (Descartes proposed mind and brain interact in the pineal gland)
- Monism: One kind of existence
- Materialism: Everything is physical/material
- Mentalism: Only the mind exists
- Identity: Mental processes are the same as certain brain processes
Mind-Body Problem (continued)
- Hard problem: Explaining why brain activity creates experience
- Easy problems: Identifying brain mechanisms enabling specific mental states (e.g., wakefulness, focus)
Mind-Body Problem (continued)
- Research difficulty: Consciousness is not directly observable. Solipsism is the belief that only one's own existence is certain.
- Questions remain regarding where consciousness occurs, if all animals/plants/rocks experience it, when in human development it begins to emerge and if artificial consciousness could theoretically be produced.
Genetics of Behavior
- Mendel (19th century): Inheritance is through genes located on chromosomes.
- Genotype: Gene pair expression (e.g., BB, Bb, bb)
- DNA: Deoxyribonucleic acid forms chromosomes, serves as a template for RNA synthesis
- Double-strand helix structure in chromosomes:
- Single-strand for RNA synthesis template
Genetics of Behavior (continued)
- Genotype Expression:
- Homozygous: Identical genes in the pair (BB or bb)
- Heterozygous: Different genes in the pair (Bb)
- Dominant Gene: Expressed regardless of the other gene in the pair;
- Recessive Gene: Only expressed if both genes in the pair are recessive
Genetics of Behavior (continued)
- Heritability: Estimate of how much variation in a trait is due to genetics. (ranges from 0 to 1)
- 0 means no heritability contribution
- 1 means all the variation in the trait is due to genes
- 0.5 means equal contributions from genes and environment.
- Determining Heritability: Comparing monozygotic and dizygotic twins, adopted children to their biological and adoptive parents
Genetics of behavior (continued)
- Modifiability of heritability -Phenotype/genetic abilities/traits can be modified (e.g. PKU via diet)
Evolution of Behavior
- Changes in gene frequencies over generations
- Changes driven by mutations, recombinations, and new genes.
- Artificial selection limits reproduction, promoting desired traits
Evolution of Behavior (Misunderstandings)
- Lamarckian Evolution: Characteristics acquired during a lifetime are inheritable. (Misconception)
- Survival of the Fittest: Evolution is about reproduction, not survival.
- Improvement: Evolution doesn't necessarily lead to improvement, but to adaptation.
- Individual vs. Species: Evolution benefits genes, not individuals or species
Sociobiology/Evolutionary Psychology
- Evolutionary perspective of behavior: why behavior is adaptive through natural selection.
- Examples: animal vision, sleep patterns, eating habits, sex differences
Sociobiology/Evolutionary Psychology (continued)
- Altruism: how genes potentially encourage altruistic behavior
- Criticisms: assumptions about a behavior being adaptive without proper testing.
Reasons for Animal Research
- Similarities in underlying behavior mechanisms across species
- Easier study of specific mechanisms in non-human animals
- Understanding of human evolution through animal studies
- Restrictions in conducting research with human participants.
Ethical Debate on Animal Research
- Techniques like brain damage, electrode implantation and hormone injections.
- Minimalist stance: Acceptable animal research with restrictions.
- Abolitionist stance: Opposing all animal research
- Current US legal and ethical standards regarding animal research involve moderation and compromise.
Careers in Biological Psychology
- Psychologists (PhDs):
- Behavioral neuroscientists: Studying brain-behavior relationships
- Neuroscientists: Neuroanatomy, biochemistry, and neurophysiology.
- Neuropsychologists: Evaluating/treating behavior in brain-damaged individuals
- Psychophysiologists: Measuring bodily changes related to activity and mental states
- Physicians (MDs):
- Neurologists: Treat brain disorders
- Neurosurgeons: Perform brain surgery
- Psychiatrists: Treat mental health conditions
