Study Notes

Brain Lobes and Areas

The brain is divided into four lobes: frontal, parietal, occipital, and temporal.
Broca's area, located in the left frontal lobe, is responsible for speech production.
Wernicke's area, situated in the left temporal lobe, is crucial for language comprehension.

Functions of Brain Lobes

Frontal lobe: Involved in decision-making, problem-solving, control of behaviors, emotions, and language.
Parietal lobe: Processes sensory information like touch, temperature, and pain.
Occipital lobe: Responsible for visual processing.
Temporal lobe: Processes auditory information and is involved in memory and emotions.

Aphasia

Broca's aphasia: Difficulty producing speech, but patients generally understand language.
Wernicke's aphasia: Fluent speech production, but often lacking meaning and comprehension.

Phineas Gage

Phineas Gage suffered a traumatic brain injury to his frontal lobe.
The case highlighted the role of the frontal lobe in personality, decision-making, and social behaviour.

Neuron Structure

Parts of a neuron: soma (cell body), dendrites, axon, myelin sheath, and axon terminals.

Functions of Neuron Components

Soma: Processes information and contains the nucleus.
Dendrites: Receive signals from other neurons.
Axon: Carries signals away from the soma.
Myelin sheath: Insulates the axon and speeds up signal transmission.
Axon terminals: Release neurotransmitters for communication with other neurons.

Significance of P-Values

P-values indicate the statistical significance of results.
A p-value of 0.01 or less is generally considered significant.
A p-value above 0.05 typically indicates results are not statistically significant.

Classical Conditioning

A learning process where a neutral stimulus is associated with an unconditioned stimulus to produce a conditioned response.
Key terms: Neutral stimulus, Unconditioned Response, Unconditioned Stimulus, Conditioned Stimulus, Conditioned Response.

Piaget's Stages of Cognitive Development

Sensorimotor (0-2 years): Learning through sensory experiences.
Preoperational (2-7 years): Symbolic thinking, egocentrism, and imagination.
Concrete Operational (7-11 years): Logical thinking about concrete events.
Formal Operational (12+ years): Abstract and moral reasoning.

Erikson's Stages of Psychosocial Development

A theory describing eight stages of development across the lifespan, each with a unique psychosocial conflict.

DSM

Diagnostic and Statistical Manual of Mental Disorders, used for diagnosis of mental disorders.

Anxiety Disorders

The DSM outlines various anxiety disorders (Generalized Anxiety Disorder, Panic Disorder, Social Anxiety Disorder, specific phobias).
Key symptoms commonly include excessive worry, avoidance, and physical symptoms.

Depressive Disorders

The DSM categorizes depressive disorders (Major Depressive Disorder, Persistent Depressive Disorder, Disruptive Mood Dysregulation Disorder).
Key symptoms comprise depressed mood, diminished interest, and potentially suicidal thoughts.

DSM-5 New Additions

Disruptive Mood Dysregulation Disorder (DMDD): temper outbursts in children
Premenstrual Dysphoric Disorder (PMDD): severe mood disturbances linked to the menstrual cycle

Obsessive-Compulsive Disorder (OCD)

Obsessions: Recurrent unwanted thoughts
Compulsions: Repetitive behaviours to reduce distress from obsessions.

Schizophrenia

Hallucinations: Sensory experiences without external stimuli (e.g., hearing voices).
Delusions: False beliefs despite evidence to the contrary.

Dissociative Disorders

Dissociative Identity Disorder (DID): Presence of multiple distinct personalities.
Dissociative disorders typically arise from trauma or extreme stress.

Critical and Sensitive Periods

Periods during development that are optimal for certain developmental skills to be learnt.

Attachment

Ainsworth's Strange Situation experiment: Observed attachment styles (secure, anxious, avoidant) of babies separated from their mothers.
Harlow's monkey experiment: Demonstrated that comfort is more important than feeding for attachment.

John Bowlby's Attachment Theory

Attachment theory suggests early relationships with caregivers establish later emotional and social development.

Language Development

Genie's case: Limited language development due to lack of early exposure.

Classical Conditioning Example

Jeremy: Loud noise (UCS) is associated with PlayStation (CS) causing fear (CR).
