Study Notes
Biological Bases of Behaviour
- The cerebral cortex consists of four lobes: frontal, parietal, occipital, and temporal, each with distinct functions.
- The primary motor cortex, located in the frontal lobe, controls voluntary movements and correlates nerve density with motor control over body areas.
- Symptoms from brain-damaged patients provide insights into affected brain areas.
- Key brain components include:
- Cerebrum: Most visible part responsible for higher functions.
- Cerebral cortex: Outer layer for conscious thought.
- Corpus callosum: Connects left and right hemispheres.
- Cerebellum: Coordinates balance and movement.
- Brain stem: Regulates vital functions (heartbeat, breathing).
- Thalamus: Routes sensory information to cortex.
- Hypothalamus: Regulates temperature, appetite, thirst.
- Pineal gland: Controls sleep-wake cycles via melatonin.
- Hippocampus: Involved in memory formation and navigation.
- Amygdala: Processes emotions such as fear and anger.
- The left hemisphere is linked to verbal and analytical tasks; the right hemisphere is connected to creativity, artistic abilities, and emotional recognition.
- Brain damage symptoms can indicate specific area impairment (e.g., loss of sight = occipital lobe damage).
Sleep
- Average individuals dream five times a night but often forget 95% of dreams.
- Dream recall varies; low dream recallers wake slower and exhibit more electrical shifts upon waking.
- Dreams occur throughout the night, predominantly in REM (90% of dreaming).
- Sleep cycles alternate between REM and NREM every 90 minutes, with increased REM duration as the night progresses.
- REM sleep features high brain activity, fluctuating heart rates, relaxed muscles, and vivid dreams, often more memorable.
- NREM sleep has regular brainwaves and less intense, brief dreams resembling waking thoughts, with increased likelihood in anxious individuals.
- Dream content is influenced by cultural background and recent experiences.
Research Methods of Psychology
- Scientific methods involve systematic observations, experiments, and analyses to study phenomena.
- Research methods aim to obtain accurate and reliable data.
- The scientific method encompasses structured research planning, conducting, and reporting.
- Hypotheses serve as testable predictions regarding variable relationships.
- Various data collection methods include:
- Direct Observation: Monitoring participant behavior with tools like stopwatches.
- Surveys: Distributing written questionnaires to gauge attitudes and behaviors.
- Interviews: Conducting face-to-face discussions for deeper insights.
- Psychological Tests: Administering standardized assessments, like IQ tests.
- Physiological Recordings: Using instruments to measure biological responses.
- Examination of Archival Records: Analyzing pre-existing data from institutions.
- Psychological research follows theories that inform hypotheses about variable relationships.
- Variables can be continuous (measure of degrees) or categorical (distinct categories).
- Standardized procedures ensure consistency for participants.
- Validity in studies must cover internal (design) and external (real-world applicability) aspects.
Key Research Concepts
- Independent variables are manipulated to observe effects on dependent variables.
- Extraneous variables may interfere with results and must be controlled.
- Participant variables relate to individual traits that may bias findings.
- Sampling methods include:
- Probability Sampling: Uses random selection, enhancing representativeness.
- Non-Probability Sampling: Includes convenience and purposive sampling, often less generalized.
- Sampling errors occur when smaller groups fail to represent the broader population accurately.
