Study Notes
Key Figures in Psychology
- Socrates emphasized introspection and self-knowledge.
- Plato believed in the concept of innate knowledge and the realm of forms.
- Aristotle focused on empirical observation and the relationship between mind and body.
- Descartes introduced dualism, separating mind and body.
Historical Contributions
- Familiarity with contributions from figures like Wundt (father of psychology), Freud (psychoanalysis), and Skinner (behaviorism) is essential.
Monism vs. Dualism
- Monism posits that mind and body are one entity, whereas dualism argues they are distinct.
Types of Psychologists
- Contemporary psychologists specialize in areas such as clinical, cognitive, developmental, and social psychology.
Scientific Method Steps
- Involves observation, hypothesis formulation, experimentation, and conclusion.
- Example: Testing the effect of caffeine on response times.
Evidence Types
- Anecdotal evidence is subjective, based on personal accounts.
- Empirical evidence is objective, derived from systematic observation or experimentation.
Psychological Methods of Investigation
- Methods include experiments, surveys, case studies, and naturalistic observation, each with unique advantages and drawbacks.
Correlation Coefficient
- Positive correlation indicates that as one variable increases, so does the other; negative correlation indicates an inverse relationship.
- Values range from -1 to +1; close to 0 indicates weak correlation.
Correlation and Causation
- Correlation does not imply causation due to:
- Coincidental relationships.
- The possibility of a third variable influencing both.
Illusory Correlation
- Occurs when a perceived relationship between two variables is mistakenly believed to exist.
Experiments and Variables
- An experiment establishes causation; independent variables are manipulated, while dependent variables are measured.
- Random selection ensures a representative sample; random assignment allocates participants to conditions.
Statistical Measures
- Mean, median, and mode are measures of central tendency calculated as follows:
- Mean: average of all scores.
- Median: middle score when sorted.
- Mode: most frequently occurring score.
Neuroanatomy and Function
- Neurons are unique for their ability to transmit electrochemical signals.
- Key parts of a neuron include dendrites (receive signals), axon (sends signals), and terminal buttons (release neurotransmitters).
Action Potential and Synapses
- Action potential is the process of firing a neuron.
- Synapses are junctions where neurotransmitters are released; transmission across synapses is slower than within neurons.
Nervous System Structure
- Hierarchal structure: Nervous system divides into the central nervous system (CNS) and peripheral nervous system (PNS).
Brain Structures and Functions
- Understand functions of major brain structures (e.g., cerebellum: motor control, amygdala: emotion processing).
- Contralateral functioning means one hemisphere controls the opposite side of the body.
Phantom Limbs
- Phantom limb sensation occurs when amputees feel pain or sensation in a missing limb, often due to brain reorganization.
Visual System Processing
- Visual information is processed through the retina, optic nerve, and visual cortex.
- Damage to specific brain areas can lead to deficits in visual perception.
Sensation vs. Perception
- Sensation is the detection of stimuli; perception is the interpretation of those stimuli.
Color Vision Theories
- Two theories include the trichromatic theory (three types of color receptors) and opponent-process theory (color perception through opposing pairs).
Motion and Perception
- Motion sickness is caused by conflicting signals between the vestibular system and visual input.
- Depth and size cues help us perceive three-dimensional space; examples include linear perspective and size constancy.
Auditory and Cutaneous Systems
- Parts of the auditory system include the cochlea (hearing) and semicircular canals (balance).
- The cutaneous system processes touch, pain, and temperature.
Chemical Systems
- Chemical sense organs include taste buds and olfactory receptors, crucial for taste and smell perception.
