Study Notes

What is Psychology?

Psychology is the scientific study of thought and behavior.
It encompasses a wide range of topics and subfields, each with its own unique insights and perspectives.
Aims to understand the causes of behavior and the differences between people.

Nature vs. Nurture

Forces shaping behavior are categorized as nature and nurture.
Heredity (nature) and experience (nurture) interact to influence thought and behavior.

Monism vs. Dualism

Psychologists generally adopt a monist approach.
This approach assumes thoughts, emotions, and behaviors have underlying physiological components.
It rejects the dualistic view of mind and body as separate entities.

Early Approaches to Psychology

Structuralism: Sought to identify fundamental structures of consciousness.
Functionalism: Emphasized the adaptive purpose of traits and behaviors.
Psychoanalytic Approach: Focused on unconscious influences in understanding the mind.
These early approaches were often subjective, leading to a preference for objective methods in modern psychology.

Research Methods in Psychology

Requires rigorous methods for collecting and analyzing data, considering the complexities of human behavior and individual variability.
Correlational studies, surveys, case studies, and experiments: Psychologists create clear operational definitions and consider potential biases.

Ethical Guidelines in Psychological Research

Informed Consent: Participants are informed about a study beforehand.
Protection from Harm: Participants are kept safe from physical or psychological harm.
Debriefing: Participants are informed about the study's true purpose after data collection.

Data Analysis

Descriptive Statistics: Summarize data (e.g., measures of central tendency).
Inferential Statistics: Interpret and draw conclusions (e.g., hypothesis testing, p-values).
Psychologists need strong statistical skills for proper study design and data analysis.

Biological Approach to Psychology

Focuses on the nervous system's structure to understand information processing.
Neurons: Communicate via electrical action potentials and chemical messages (neurotransmitters).
The nervous system has divisions for voluntary and involuntary responses. Communication involves neurotransmitters and hormones from the endocrine system.
The Brain: Includes subcortical structures (e.g., amygdala, hypothalamus, hippocampus) and the cerebral cortex (divided into two hemispheres connected by the corpus callosum). Each hemisphere has four lobes processing information.
Brain Imaging Techniques: Studying brain structure (CAT scans, MRI) and function (EEG, PET scans, fMRI scans).

Genetics and Behavior

Investigates the influence of genes on behavior.
Molecular Genetics: Studies the role of individual genes.
Behavioral Genetics: Examines the overall genetic influence on traits and behaviors, using heritability calculations to gauge genetic contributions.
Twin Studies: Frequently employed to study genetic influence on behavior.

Sensation and Perception

Examines sensory information collection and processing.
Absolute Thresholds: Minimum stimulation for stimulus detection.
Difference Thresholds: Minimum detectable difference between stimuli.
Transduction: Conveying physical stimuli (e.g., light waves, sound waves) into neural signals.
Perception: Interpreting sensory information, influenced by experience and cultural factors.

States of Consciousness

Investigates different states of awareness.
- Conscious: Current awareness.
- Preconscious: Easily accessible, non-current awareness.
- Subconscious: Below conscious awareness, influencing thoughts.
- Unconscious: Completely inaccessible awareness.
- Non-conscious: Processes outside awareness (e.g., breathing).
Alertness and State of Consciousness: Awareness levels depend on alertness and state of consciousness.
Sleep Research: Studying sleep stages, functions, and disorders like insomnia and narcolepsy.
Meditation and Hypnosis: Practices influencing consciousness.
Psychoactive Drugs: Substances altering consciousness via nervous system effects (e.g., stimulants, depressants, hallucinogens).

Behavioral Approach to Psychology

Emphasizes observable behaviors (early 20th century).
Classical Conditioning: Learning associations between stimuli and responses.
Neutral Stimulus: Doesn't initially elicit a response.
Unconditioned Stimulus: Automatically elicits a response.
Unconditioned Response: Automatic response to unconditioned stimulus.
Conditioned Stimulus: Neutral stimulus becoming linked to response.
Conditioned Response: Learned response to conditioned stimulus.
Operant Conditioning: How reinforcement (positive or negative) or punishment strengthens or weakens behavior.
Schedules of Reinforcement: Patterns of reinforcement shaping behavior.

Cognitive Revolution

Focus shifted to internal mental processes (e.g., memory, language).
Cognitive Processes: Objectively measurable.

Memory Research

How we encode, store, and retrieve information.
Models of Memory: Three-Box, Working Memory Model.
Types of Memory: Explicit (conscious recall), Implicit (unconscious skills).
Flawed Memories: Forgetting, suggestibility, false memories.
Reconstruction of Memories: Memories are constantly reassembled, leading to distortion.
Schema: Cognitive frameworks organizing knowledge.
Biological Factors in Memory: Hippocampus's role in memory formation, Long-Term Potentiation.
Emotion and Memory: Emotional events can enhance or impair recall.
Educational Applications: Strategies for improving learning.

Language Development

How we develop complex language skills.
Influences on Language Development: Biological, cognitive, social factors.
Language and Cognition: Language influences our perception and thinking.

Problem-Solving and Decision-Making

Can occur with varying levels of awareness.
Dual Process Model: Automatic (System 1) and deliberate (System 2) processing.
Cognitive Biases: Errors in judgments arising from heuristics (e.g., availability, representativeness, framing).

Intelligence

Cognitive abilities, information processing, problem-solving.
Definitions of Intelligence: Multiple Intelligences, Triarchic Theory, Emotional Intelligence.
"g" Factor: General cognitive ability.
Fluid and Crystallized Intelligence: Fluid (new problems) and crystallized (accumulated knowledge).
Intelligence Assessments: Wechsler Scales, Raven's Matrices.
Distribution of Intelligence: Normal distribution (mean 100, standard deviation 15).
Intellectual Disability, Giftedness: Ranges of scores.
Heritability of Intelligence: Complex interaction between genes and environment.
Flynn Effect: Gradual increase in intelligence scores over time.

Personality

Patterns of thinking and behaviors across individuals.
Early Approaches to Personality: Freud's Psychoanalytic Theory, stages of development, defense mechanisms.
Trait-Based Approaches: Big Five personality traits (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism).
Projective Techniques: Psychological assessments with ambiguous stimuli (e.g., Rorschach).

Causes of Personality Differences

Biological Factors: Genes, hormones, neurotransmitters.
Cognitive Factors: Self-perception, self-belief, self-efficacy, self-perception theory, locus of control.
Social Comparison: Comparing oneself to others.
Existential Psychology: Coping with mortality and finding meaning.
Humanistic Psychology: Striving for personal growth.

Emotions

Impact of emotions on thoughts and behaviors, communication, and motivation.
Theories of Emotion: James-Lange, Cannon-Bard, Schachter-Singer.
Universal Expressions of Emotion: Six basic emotions (Ekman).
Motivation: Emotions drive behavior, including drives (basic biological needs) and drive reduction theory.
Types of Motivation: Intrinsic, extrinsic, and overjustification effect.

Developmental Psychology

Individual changes across the lifespan.
Early Life Development: Biological, perceptual, and physiological maturation.
Cognitive Development: Piaget's stages.
Social Development: Theory of mind, moral reasoning, attachment, parenting styles.
Later Life Development: Changes in adulthood (e.g., intelligence, identity, goals).

Health Psychology

Biological, cognitive, and environmental factors influencing health.
Stress and Health: Acute and chronic stressors, impact on physical systems, hardiness, coping strategies.

Individual behaviors and thoughts within social contexts.
Social Influence: Conformity, persuasion, compliance, obedience.
Attributing Causes to Behavior: Individual vs. situational factors.
Social Influences on Relationships and Groups: Factors influencing relationships, groups, and societal interactions.
Group Dynamics and Consequences: Group memberships, outcomes, and dynamics (groupthink).

Psychological Disorders

Investigating negative thoughts and behaviors (deviant, dysfunctional, distressing).
Biological, behavioral, cognitive, and social considerations.
Challenges in defining and classifying disorders.

The Diathesis-Stress Model

Genetic risk factors and environmental influences.
Clinical psychologists/psychiatrists aim to understand causes/consequences.

Diagnosing and Classifying Disorders

DSM-5 categorizes disorders (e.g., anxiety, depression, schizophrenia, personality).
Challenges in accurate diagnosis due to variance.

Interventions and Treatment Effectiveness

Treatments: Biological, psychotherapeutic, and other interventions.
Evaluating effectiveness is complex (individual variability, placebo effect, bias).

Lifestyle Factors and Psychological Well-being

Lifestyle factors (diet, exercise, meditation, faith, social support) impacting mental health.
Benefits for reducing risks and severity of psychological disorders.
