Comprehensive Study Guide: Learning, Memory, and Developmental Psychology

Learning and Behavioural Psychology

Behaviourism Theorists

Behaviourism is a foundational approach in psychology that emphasizes the study of observable behaviours and the processes by which they are learned. Key theorists include:

• Pavlov: Known for classical conditioning research.

• Watson: Extended classical conditioning to humans.

• Thorndike: Developed the law of effect and connectionism.

• Skinner: Pioneered operant conditioning.

Classical Conditioning

Classical conditioning is a learning process in which a neutral stimulus becomes associated with a meaningful stimulus, eliciting a similar response.

• Pavlov's Research:

  • Unconditioned Stimulus (US): Naturally elicits a response.

  • Unconditioned Response (UR): Natural reaction to the US.

  • Neutral Stimulus (NS): Initially does not elicit the UR.

  • Conditioned Stimulus (CS): Previously NS, now elicits response after association.

  • Conditioned Response (CR): Learned response to the CS.

  • Factors in Classical Conditioning: Timing, frequency, and predictability of pairings.

  • Stimulus Generalisation and Discrimination: Generalisation is responding similarly to similar stimuli; discrimination is distinguishing between different stimuli.

  • Extinction: Weakening of the CR when the CS is presented without the US.

  • Spontaneous Recovery: Reappearance of the CR after a rest period.

• Watson's Research:

  • Demonstrated conditioned emotional responses (e.g., Little Albert experiment).

• Applications:

  • Taste aversion, chemotherapy, fear responses, drug use, advertising.

Operant Conditioning

Operant conditioning involves learning through consequences, where behaviours are strengthened or weakened by reinforcement or punishment.

• Differences Between Classical and Operant Conditioning: Classical conditioning pairs stimuli, while operant conditioning pairs behaviour and consequence.

• Skinner's Research:

  • Shaping: Gradually guiding behaviour toward a desired outcome.

  • Reinforcement:

    • Positive: Adding a desirable stimulus.

    • Negative: Removing an aversive stimulus.

    • Primary: Naturally reinforcing (e.g., food).

    • Conditioned: Learned reinforcers (e.g., money).

  • Punishment:

    • Positive: Adding an aversive stimulus.

    • Negative: Removing a desirable stimulus.

  • Schedules of Reinforcement:

    • Continuous: Every response is reinforced.

    • Partial: Only some responses are reinforced.

    • Fixed Ratio, Variable Ratio, Fixed Interval, Variable Interval.

• Other Concepts:

  • Chaining, discrimination, generalization, delayed reinforcement, habituation, Premack principle, extinction.

Cognitive Perspectives on Learning

• Cognitive Learning:

  • Cognitive map, latent learning, insight learning, discovery learning.

• Latent Learning: Learning that occurs without immediate reinforcement and is not demonstrated until there is motivation.

• Observational Learning (Bandura):

  • Social learning theory: Learning by observing others.

  • Four processes: Attention, retention, reproduction, motivation.

  • Imitation, mirror neurons, media violence effects.

Memory and Cognitive Neuroscience

Cognitive Neuroscience of Memory

Memory involves complex neural processes and structures in the brain.

• Synaptic changes: Long-term potentiation (LTP).

• Hippocampus and amygdala: Key roles in memory formation and emotional memory.

• Hormones and memory: Stress hormones can enhance or impair memory.

• Biology of memory deterioration: Neurodegenerative diseases (e.g., Alzheimer's).

• Stored memories and the brain: Distributed across neural networks.

Atkinson-Shiffrin Multistore Model

This model describes three types of memory stores:

• Sensory Memory: Brief storage of sensory information (iconic and echoic memory).

• Short-Term Memory (STM): Limited capacity and duration; subject to decay and interference.

• Long-Term Memory (LTM):

  • Declarative (explicit) memory: Episodic (events) and semantic (facts).

  • Non-declarative (implicit) memory: Procedural (skills, habits), priming, classical conditioning.

Working Memory

• Components: Phonological loop, visuospatial sketchpad, episodic buffer, central executive.

Processes of Memory

• Encoding: Transforming information into a storable form.

• Storage: Maintaining information over time (shallow, deep, consolidation).

• Retrieval: Accessing stored information (recall, recognition, encoding specificity, state-dependent and mood-dependent memory).

Other Memory Topics

• Emotional memories, flashbulb memories, autobiographical memory.

• Ebbinghaus's research: Curve of forgetting.

• Causes of forgetting: Decay, interference, retrieval failure.

• Age-related memory loss: Changes in brain structure and function.

Developmental Psychology

Principles of Growth and Development

• Physical growth trends: Cephalocaudal and proximodistal patterns.

• Continuous vs. discontinuous development: Gradual vs. stage-like changes.

• Research designs: Cross-sectional and longitudinal studies.

• Nature vs. nurture influences: Genetic and environmental factors.

Attachment

• Key aspects: Theories of attachment, neurobiology, attachment styles.

• Problems with Ainsworth's work: Cultural and contextual limitations.

Developmental Domains

• Physical, language, cognitive, and social-emotional development.

Stages of Development

• Prenatal Development: Stages from conception to birth, including prenatal brain development and factors affecting development.

• Infancy: Birth to 1 year; myelination, synaptogenesis, sensory and motor development, reflexes, emotional development.

• Toddlerhood: 1 to 2.5 years; brain, motor, and emotional development.

• Early Childhood: 2.5 to 6 years; brain, motor, social, and emotional development.

• Middle Childhood: 6 to 12 years; continued development in all domains.

• Adolescence: 12 to 18 years; brain, physical, cognitive, and social-emotional changes.

• Emerging Adulthood: 18 to mid/late twenties; transition to adult roles.

Cognitive Development

• Piaget's Theory: Stages of cognitive development, including sensorimotor, preoperational, and concrete operational stages.

• Key Concepts: Schema, assimilation, accommodation, object permanence, egocentrism, conservation.

• Evaluation: Contributions and challenges of Piaget's work.

Vygotsky's Sociocultural Theory

• More knowledgeable other, zone of proximal development, scaffolding, importance of language.

• Contributions of Vygotsky's work.

Comparing Piaget and Vygotsky

• Both theories address cognitive development but differ in emphasis on social context and stages.

Theory	Main Focus	Key Concepts
Piaget	Stages of cognitive development	Schema, assimilation, accommodation, object permanence
Vygotsky	Social and cultural influences	Zone of proximal development, scaffolding, language
