Study Notes
Nature vs. Nurture
- Gene: A hereditary unit that dictates an organism's traits and functions.
- DNA: Stores and transmits genetic information, essential for growth, development, and reproduction.
- Chromosomes: Responsible for genetic replication and distribution.
- Shared Environment: Refers to familial and home upbringing impacting behavior and traits.
- Behavioral Genetics: Studies the influence of heredity on behavior, addressing the role of genes in personality traits, abilities, and disorders.
- Sir Francis Galton: Pioneered twin studies for heritability of traits, suggested that nature plays a significant role in producing "men of genius."
Genome-Wide Association Study
- Conducted in 2010, involves DNA sampling to identify genetic variants linked to traits or disorders.
Research Types in Biopsychology
- Pure Research: Driven by curiosity to acquire knowledge without immediate benefits.
- Applied Research: Aims to provide direct benefits to humanity.
Major Divisions of Biopsychology
- Physiological Psychology: Investigates neural mechanisms behind behavior.
- Neuropsychology: Examines psychological consequences of brain damage.
- Comparative Psychology: Studies behavior across different species.
- Psychophysiology: Explores the relationship between physiological processes and psychological phenomena.
- Neuropharmacology: Studies drug effects on neural activity.
- Cognitive Neuroscience: Examines higher intellectual processes and their biological basis.
Animal Research Ethics
- Animal Welfare Committee: Ensures humane treatment of animals in research.
- 3Rs Principle: Reduction (minimizing animal use), Refinement (improving care), Replacement (substituting with alternative methods).
Memory Conditions
- Korsakoff's Syndrome: Results in anterograde amnesia (inability to form new memories) often due to thiamine deficiency.
- Anterograde Amnesia: Retention of past memories, but inability to make new ones.
- Retrograde Amnesia: Loss of past memories but capacity to form new ones.
Lobotomy
- Walter Jackson Freeman: Medical pioneer who developed lobotomy as psychosurgery.
- Dr. Egas Moniz: Nobel Prize recipient who advanced prefrontal lobotomy.
Genetics and Personality
- Mendelian Genetics: Gregor Mendel's work on inheritance is fundamental to understanding genetic influence.
- Dominant Trait: Dominates over recessive traits; expressed in offspring if present.
- Temperament Studies: Emphasize genetic contributions (20-60%) to personality; children exhibit traits early on.
Feral Children
- Feral children are isolated from human contact, lacking language skills, social norms, and exhibiting developmental delays as a result of insufficient interaction and learning opportunities.
Key Characteristics of Feral Children
- Lack of Language Skills: Limited to sounds or gestures due to absent exposure to human speech.
- Social Isolation: Difficulty in normal human interactions and comprehension of social behaviors.
- Physical Behavior: May mimic animal-like behaviors due to their upbringing.
- Developmental Delays: Cognitive and emotional milestones may be significantly delayed.
