Social Cognition, Biological Psychology, Developmental Psychology, Culture and psychology, and Indigenous psychology
Social Cognition and Influence
Social psychology studies how individuals' thoughts, feelings, and behaviors are influenced by others. Key topics include the need to belong, attitudes, persuasion, prejudice, and attribution.
The Need to Belong
Humans have a biological need for interpersonal bonds, which is evolutionarily adaptive. Social exclusion can lead to mood and anxiety problems, unhealthy behaviors, and increased aggression.
Attitudes
Attitudes are psychological tendencies expressed by evaluating entities with favor or disfavor. They consist of:
- Cognition (thoughts)
- Affect (feelings)
- Behavior (actions)
Attitude strength, importance, and accessibility influence our thinking. Attitudes can be implicit (unconscious) or explicit (deliberately formed).
Attitudes and Behavior
Attitudes don't always predict behavior. Factors such as accessibility, shared attitudes, and attitude strength increase predictability. The theory of planned behavior links specific attitudes, subjective norms, and perceived behavioral control to behavior.
Attitude Change / Persuasion
The Yale Attitude Change Approach focuses on the source, context, message, and audience. The Elaboration Likelihood Model describes two routes to persuasion:
- Central Route: careful consideration of information.
- Peripheral Route: relies on superficial cues.
Cognitive Dissonance Theory
People seek consistency among their attitudes and beliefs. Inconsistencies lead to dissonance, which individuals try to reduce through rationalization.
Self-Perception Theory
People infer their feelings by observing their own behavior, especially when initial feelings are unclear.
Culture & Cognitive Dissonance
Cognitive dissonance varies across cultures. Individualistic cultures focus on self-esteem, while collectivist cultures emphasize social expectations.
Social Cognition
Social cognition involves how people think about themselves and the world. Schemas are organized patterns of thought. Identity is shaped by self-perceptions, values, beliefs, and the environment.
Prejudice
Prejudice includes stereotypes (overgeneralized beliefs), negative attitudes, in-group bias, and out-group homogeneity. Types include racism, sexism, religious prejudice, and homophobia.
Reducing Prejudice
Contact Hypothesis: Contact between groups can reduce prejudice under specific conditions like equal status and cooperation.
Racism
Racism can be subtle (political correctness), implicit (unknowing discrimination), or explicit (intentional harmful attitudes).
Ostracism
Ostracism (being ignored or rejected) affects belonging, self-esteem, control, and meaning.
Attribution
Attributions are explanations for behavior, influenced by internal (personal factors) and external (situational factors) causes.
Fundamental Attribution Error
The fundamental attribution error is the tendency to overemphasize internal factors and underestimate situational factors when explaining others' behavior.
Actor-Observer Effect
The actor-observer effect involves attributing others' behavior to internal causes while attributing our own actions to external causes.
Self-Serving Bias
Self-serving bias is the tendency to take credit for success and attribute failure to external causes.
Biological Psychology
Biological psychology studies the biological basis of behavior, crucial for understanding the heterogeneity of etiologies (genes, proteins, cells, circuits, environment) and holistic guidance involving lifestyle factors.
Learning Outcomes
- Understand the nervous system and its components.
- Understand the central and peripheral nervous systems.
- Understand the endocrine system.
- Understand the roles of genetics and environment.
Central Nervous System (CNS)
The nervous system is the body’s communication network involving the brain and spinal cord. It controls movement, sensation, and automatic functions.
Basic Units of the Nervous System
- Neurons: process and transmit information.
- Glial Cells: immune cells, protect from infection and damage.
- Extracellular Matrix (ECM): environment surrounding brain cells.
Neuron Structure
Dendrites: receive signals.
Cell Body (Soma): integrates signals.
Axon: transmits signals.
Myelin Sheath: insulates axon.
Nodes of Ranvier: facilitate rapid conduction.
Axon Terminal: transmits signals to other cells.
Glia
Oligodendrocytes: wrap myelin around axons.
Microglia: immune cells.
Astrocytes: ensheath synapses and wrap around blood vessels.
Spinal Cord
- Afferent Fibers: carry sensory information to the brain.
- Efferent Fibers: carry motor commands from the brain.
- White Matter: myelinated axons.
- Gray Matter: cell bodies and synapses.
- Posterior (Dorsal) Horn: sensory processing.
- Lateral Horn: autonomic functions.
- Anterior (Ventral) Horn: motor control.
Brain Structure
- Cerebrum: largest part, divided into hemispheres, gyri (ridges) and sulci (grooves).
- Cerebellum: motor coordination and balance.
- Brainstem: connects brain to spinal cord (midbrain, pons, medulla oblongata).
Lobes of the Brain
- Frontal Lobe: executive functions, planning.
- Parietal Lobe: sensory processing and spatial awareness.
- Temporal Lobe: auditory processing and memory.
- Occipital Lobe: visual processing.
Benefits of a Central Nervous System
- Processing external environment information.
- Monitoring internal states.
- Regulating internal states.
Homeostasis and Allostasis
- Homeostasis: maintaining a stable internal environment.
- Allostasis: achieving stability through change.
- Allostatic Load: cumulative burden of chronic stress.
- Allostatic Overload: stress response becomes damaging.
Peripheral Nervous System
- Central Nervous System: brain and spinal cord
- Peripheral Nervous System: cranial nerves and spinal nerves
- Autonomic Nervous System: controls heart muscle, smooth muscle, and glands.
- Parasympathetic Division: "Rest and digest"
- Sympathetic Division: "Active and alert"
- Somatic Nervous System: Controls voluntary skeletal muscles.
- Autonomic Nervous System: controls heart muscle, smooth muscle, and glands.
Somatic Nervous System
Involves upper motor neurons in the brain and lower motor neurons in the brain stem and spinal cord that connect to skeletal muscles.
Autonomic Nervous System
- Parasympathetic Nerves: promote "rest and digest" functions.
- Sympathetic Nerves: prepare body for "fight or flight."
Sympathetic Response
Fight, Flight, Freeze, and Fawn responses are characterized by increased heart rate, blood moving away from digestive organs, shaking, pupil dilation, and sweating.
Endocrine System
Includes the hypothalamus, pineal gland, pituitary gland, thyroid gland, thymus gland, adrenal glands, pancreas, ovary glands (female), testis (male).
Hypothalamic-Pituitary-Adrenal (HPA) Axis
Regulates stress and emotion. The hypothalamus releases CRF (corticotropin- releasing factor) and AVP (arginine vasopressin), which stimulate the pituitary gland to release ACTH (adrenocorticotropic hormone). ACTH then causes the adrenal glands to release cortisol and adrenaline.
Hypothalamic-Pituitary-Gonadal (HPG) Axis
Controls reproductive behaviors through the release of GnRH (gonadotropin-releasing hormone) from the hypothalamus. This stimulates the anterior pituitary to release LH (luteinizing hormone) and FSH (follicle-stimulating hormone), which affect the testes (testosterone) or ovaries (estrogen and progesterone).
Hypothalamic-Pituitary-Thyroid (HPT) Axis
Regulates metabolism and mood. The hypothalamus releases TRH (thyrotropin- releasing hormone), which stimulates the pituitary to release TSH (thyroid-stimulating hormone). TSH then stimulates the thyroid to release T4 and T3, which affect TH- sensitive cells.
Pineal Gland
Produces melatonin, which regulates sleep and circadian rhythms. The suprachiasmatic nucleus (SCN) inhibits melatonin production in response to light.
Genetics and Psychological Functioning
Genes are segments of DNA located on chromosomes. An allele is a variant form of a gene. Individuals can be homozygous (two identical alleles, e.g., SS, BB, bb) or heterozygous (two different alleles, e.g., Bb).
Genes in Brain Development
Genes orchestrate brain development (neurogenesis, migration, axon outgrowth, etc.).
Key developmental processes:
- Neurulation.
- Neurogenesis.
- Migration from the ventricular zone.
- Synaptogenesis.
- Competitive elimination.
- Programmed cell death.
- Myelination.
- Dendritic and axonal arborization.
Genes Across the Lifespan
Genes influence brain function throughout life by maintaining networks, regulating apoptosis and neurotransmitter activity, and facilitating waste clearance.
Epigenetics
Epigenetics involves DNA modifications that alter gene expression without changing the DNA sequence. Environmental factors influence these modifications.
Environment and the Brain
Various environmental factors influence the brain, including social interaction, stress, emotion, cognition, sleep, discrimination, socioeconomic disparities, pollutants, food, and exercise.
Biopsychosocial Model of Mental Health
Mental health is influenced by biological, psychological, and social factors.
Developmental Psychology
Developmental psychology studies how the brain, body, and behavior change over the lifespan, including personality, behavior, cognition, and social, emotional, and biological domains.

- Stress (Cortisol).
- Folate deficiency.
The Neonatal Environment
Apgar Test: Evaluates newborns based on heart rate, respiratory effort, muscle tone, color, and reflex irritability.
Newborn Development
Newborns come with preloaded reflexes (Moro, Palmar, Swimming, Rooting).
Infant and Childhood Cognition: Piaget's Theory
- Cognitive development happens in discontinuous, sequential, and universal stages.
- Children are active explorers who construct knowledge through their own activity.
- Exploration leads to the creation of schemas (mental categories).
- Equilibrium is the effort by the organism to exist in harmony with its environment, reducing cognitive conflict (disequilibrium).
Schema Development
- Assimilation: Fitting new experiences into existing schemes.
- Accommodation: Modifying schemes as a result of new experiences.
Periods of Cognitive Development
- Sensorimotor Period (0-2 years): Object permanence
- Preoperational Period (2-7 years): Egocentrism, Animism, symbolic thinking.
- Concrete Operational Period (7-12 years): understanding basic concepts such as number, classification, and conservation.
- Formal Operational Period (12 years & up): abstract and hypothetical thinking.
Vygotsky’s Theory
- Social constructivist. Children are more like apprentices than tiny scientists. Scaffolding.
Attachment and Emotional Development
- Crying is a baby's only way to communicate needs.
- Attachment Theory (Bowlby): Emotional problems in orphans resulted from a lack of a strong affectional tie.
- Four stages of attachment:
- Pre-attachment stage (birth to 6-8 weeks)
- Attachment in the making (6-8 weeks to 6-8 months)
- True attachment (6-8 months to 18 months)
- Reciprocal relationships (18 months on)
Attachment Styles

Emerging Adulthood (18-25 years) is a period of development between adolescence and adulthood.
Cognitive Development in Early Adulthood
Neural connections peak cognitive abilities improve. Fluid and crystallised intelligence
Social Development in Early Adulthood
Becoming parents: enter Erikson's intimacy versus isolation stage.
Cognitive and Social Development in Middle and Late Adulthood. In late adulthood there may be noticeable declines in fluid intelligence, attention, and memory. Retirement is a major life event. Integrity vs. despair struggle occurs (Erikson).
Culture and Psychology
Culture and psychology discusses definitions dimensions, and frameworks.
What is Culture?
Culture is shared values, beliefs, attitudes, and behaviors that distinguish members of one group from members of others. Not nationality, race, or ethnicity. Cultural shift
Cultural and Cross-Cultural Psychology
Enculturation: Process by which values and norms of a culture are passed on to its members.
Cultural Psychologists: Study culture-specific ways.
Cross-Cultural Psychologists: Compare similarities and differences across cultures.
Cross-Cultural Psychology: Definition
Comparative study of behavior in different cultures. Look at both unique behaviors and universal actions.
Research Methods in Cultural and Cross-Cultural Psychology
Emic Perspective (culture-specific) and Etic Perspective (universal).
Challenges in Research
Research methods, equivalent samples, interpreting results, researcher bias, and sensitive issues.
Dimensions of Culture: Individualism-Collectivism
Individualism prioritizes individuals versus Collectivism prioritizes groups
Dimensions of Culture
Monochronic/Polychronic (Time). Cultural Display Rules (Emotion) Conversational distance (space) High/Low Context cultures. Tight/Loose Cultures
Vertical versus Horizontal
Vertical Individualistic vs. Vertical Collectivist. Horizontal Individualistic vs. Horizontal Collectivist.
Colonization and Diversification
Colonization: Invasion by a new group involving control and assertion of sovereignty that involves violence and exploits existing natural and human resources. Multiculturalism and Culture Shock.
Acculturation and Assimilation
Acculturation: Changes groups and individuals undergo when they encounter another culture.
Berry’s four orientations: Assimilation, integration, separation, marginalization.
Refugees and Asylum Seekers
A person whose claim has not yet been finally decided upon. Post-migration aspects of resettlement and acculturation can be very difficult and have increased rates of mental health.
Ethnic Identity
Ethnic identity is the culture, religion, geography, language, and practices shared by individuals connected by loyalty and kinship.
Culturally Responsive Psychologists

Contradictory to the UN Declaration on the Rights of Indigenous People
States Indigenous people have the right to determine their own identity. Reframing 'cultural load' places the load where it belongs; with the colonial project.
Colonial Load
The load placed knowingly and unknowingly on First Nations people. Biases, assumptions, expectations and entitlement
Cultural Responsibility
Cultural Responsibility is how community would like us to show up, and how we've been taught to show up for family, community and Country.
