### Chapter 1: The Foundations of Psychological Science **Key Concepts:** 1. **Commonsense Psychology:** Many "commonsense" beliefs are false due to lack of critical evaluation and biases such as confirmation bias. - Superstition: Unfounded beliefs. - Pseudoscience: Claims that sound scientific but lack evidence. - Science: Objective approach using observations and experiments. 2. **What Psychologists Do:** - Research types: Basic (knowledge-focused) and applied (problem-solving). - Specialties include clinical, developmental, forensic, and more. - Clinical psychologists address mental disorders; counseling psychologists help with mild issues. 3. **Historical Perspectives:** - Structuralism: Analyzing conscious experience via introspection. - Functionalism: Focus on how behaviors help adaptation. - Behaviorism: Study of observable behavior. - Psychoanalytic: Unconscious mind’s influence. - Humanistic: Emphasis on free will and growth. 4. **Biopsychosocial Model:** Explains behavior through biological, psychological, and social perspectives. 5. **Psychological Science Methods:** - Experimental: Establishing cause-effect relationships. - Nonexperimental: Observational and correlational studies. --- ### Chapter 2: Brain and Behavior **Key Concepts:** 1. **Nervous System:** - Central (CNS): Brain and spinal cord. - Peripheral (PNS): Connects CNS to rest of the body. 2. **Brain Research:** - Techniques: EEG, MRI, PET scans.  - Localization of function: Specific areas responsible for tasks. 3. **Cerebral Cortex:** - Divided into lobes (frontal, parietal, occipital, temporal). - Functions: Decision-making, sensory processing, vision, and memory. 4. **Limbic System:** Emotion and memory regulation (includes hippocampus, amygdala). 5. **Endocrine System:** Hormone regulation affecting behavior. --- ### Chapter 3: Human Development **Key Concepts:** 1. **Nature vs. Nurture:** - Nature: Genetic inheritance. - Nurture: Environmental influences. - Epigenetics: Interaction between genes and environment. 2. **Developmental Stages:** - Prenatal: Germinal, embryonic, fetal. - Childhood: Physical and social growth. - Adolescence: Identity and cognitive changes. - Adulthood: Stability and aging. 3. **Key Theories:** - Piaget: Cognitive development (sensorimotor to formal operational stages). - Erikson: Psychosocial stages (e.g., trust vs. mistrust). --- ### Chapter 4: Sensation, Attention, and Perception **Key Concepts:** 1. **Sensation and Perception:** - Sensation: Raw data received by sensory organs. - Perception: Interpretation of sensory data. 2. **Processes:**  - Transduction: Conversion of sensory input to neural signals. - Thresholds: Absolute (minimum detectable) and difference (smallest noticeable change). 3. **Attention:** - Influenced by intensity, novelty, and relevance. - Multitasking often involves task-switching. 4. **Perceptual Processing:** - Bottom-up: Sensory-driven. - Top-down: Experience and expectations-driven. --- ### Chapter 6: Conditioning and Learning **Key Concepts:** 1. **Classical Conditioning (Pavlov):** - Pairing a neutral stimulus (NS) with an unconditioned stimulus (US) to elicit a conditioned response (CR). - Terms: Extinction, spontaneous recovery, generalization, discrimination. 2. **Operant Conditioning (Skinner):** - Behavior influenced by consequences. - Reinforcement: Increases behavior (positive/negative). - Punishment: Decreases behavior. 3. **Observational Learning:** Learning through observing others (Bandura’s Bobo doll study). --- ### Chapter 7: Memory **Key Concepts:** 1. **Memory Systems:** - Sensory: Brief retention of sensory information. - Short-term: Limited capacity (working memory). - Long-term: Unlimited storage. 2. **Processes:** - Encoding: Converting information into a memory.  - Storage: Maintaining information. - Retrieval: Accessing stored information. 3. **Forgetting:** - Causes: Interference, decay, retrieval failure. 4. **Improving Memory:** - Mnemonics, rehearsal, organization, and chunking. --- ### Chapter 8: Cognition, Language, and Creativity **Key Concepts:** 1. **Cognition:** Mental processes like thinking, problem-solving, and decision-making. - Heuristics: Mental shortcuts. - Biases: Confirmation, availability, etc. 2. **Language:** - Structure: Phonemes, morphemes, syntax. - Development: Stages from babbling to full sentences. 3. **Creativity:** - Divergent thinking: Generating multiple solutions. - Convergent thinking: Focusing on a single solution.
