Study Notes

What is Psychology?

Psychology studies behavior and mental processes, integrating various approaches for a comprehensive understanding.

Psychological Perspectives

Psychoanalysis: Focuses on unconscious drives influencing behavior; led to modern psychodynamic theories.
Behaviorism: Emphasizes observable behavior regulated by rewards and punishments; forms the basis of today's behavioral psychology.
Cognitive Psychology: Highlights the role of cognition in understanding behavior; foundational to the current cognitive perspective.
Humanism: Centers on individual potential and self-actualization, contrasting with deterministic views of previous theories.

Research Methodology

Theory: Hypothesizes that people are more attracted to those who are different (opposites attract).
Hypothesis: Experiments will show a preference for those different rather than similar.
Independent Variable: The similarity or difference among individuals.
Dependent Variable: The level of preference or likability.
Method: Correlational approach will be employed to analyze relationships.

Research Methods Pros and Cons

Descriptive Method:
- Pros: Provides specific details about a theory.
- Cons: Limited generalizability; may lack robustness.
Correlation Method:
- Pros: Identifies systematic relationships between variables.
- Cons: Cannot establish causation; correlation does not imply causation.
Experimental Method:
- Pros: Allows for causal conclusions through controlled experimentation.
- Cons: May lack ecological validity; results may not be generalizable.

Statistics in Psychology

Descriptive Statistics: Summarizes data to describe observed sets.
Inferential Statistics: Draws conclusions from data samples to infer about populations.
Mean Usage: Avoid using the mean in non-normally distributed datasets or with high skewness.

Ethics in Research

Safeguards for Participants:
- Risk assessment during study design to minimize potential harm.
- Availability of support or counseling post-participation.
- Ensuring confidentiality and anonymity in data reporting.
Deception: Ethical considerations vary; contextual harm vs. research value affects acceptability.

Nervous System vs. Endocrine System

Nervous System: Comprised of the CNS (brain, spinal cord) and PNS (peripheral nerves) for rapid signaling; uses neurotransmitters for communication.
Endocrine System: Involves hormone secretion into the bloodstream for prolonged effects; essential for slow, sustained responses.

Functions of the Nervous System

Main role is processing and interpreting information for body function coordination.
CNS: Processes information and formulates responses.
PNS: Transports signals to/from the CNS, regulating movement, sensation, and organ functionality.

Brain Functionality and Damage Effects

Broca’s Area: Damage leads to aphasia, affecting speech production.
Wernicke’s Area: Damage leads to nonsensical speech despite fluency.

Sensation vs. Perception

Sensation: The reception of stimuli through sensory organs.
Perception: The brain’s organization and interpretation of sensations, forming a coherent understanding of the environment.
