Psychology’s Big Issues

&Approaches

Philosophical Developments

• THE Question: Nature vs. Nurture

• Inherited vs. Environment• Are our physical and mental abilities determined

by our genes or our experiences?• What has the biggest effect on behavior?• What are the interactions between genetics and

environment?• NURTURE WORKS ON WHAT NATURE

Bio-Psycho-Social ModelAnalysis

PsychologicalApproaches

Psychological Perspectives• Each view behavior from a particular

perspective• Method of classifying a collection of ideas• Also called “schools of thought”• Also called “psychological approaches”

Cognitive Perspective

• Focus: On how people think and process information• Behavior is explained by how a person interprets the

situation• How is knowledge acquired, organized, remembered,

and used to guide behavior?• Influences include

– Piaget – studied intellectual development– Chomsky – studied language– Cybernetics – science of information processing

Biological Perspective

• Focus: How our biological structures and substances underlie a given behavior, thought, or emotion

• Behavior is explained by brain chemistry, genetics, glands, etc.

• Focus may be at various levels– individual neurons– areas of the brain– specific functions like eating, emotion, or learning

• Interest in behavior distinguishes biological psychology from many other biological sciences

Social-Cultural Perspective• Focus: How thinking and behavior change

depending on the setting, situation or culture

• Behavior is explained by the influence of other people present

BehavioralPerspective

• Focus: How we learn through rewards, punishments, and observation

• View of behavior based on experience or learning– Classical conditioning - Pavlov– Operant conditioning – Skinner– Founded by James Watson

Humanistic Perspective

• Focus: How healthy people strive to reach their full potential

• Behavior is explained as being motivated by satisfying needs (safety, hunger, thirst, etc.), with the goal of reaching one’s full potential once basic needs are met.

• Developed by Abraham Maslow and Carl Rogers– behavior reflects innate ‘actualization’ – focus on conscious forces and self perception– more positive view of basic forces than Freud’s

Positive Psychology

• Modern “Humanistic Psychology”• Focus: To study and promote optimal human

functioning– Help people discover their human potential and fullfillment

• Martin E.P. Seligman is a major advocate• Should promote building positive qualities of

people rather than focus on what’s wrong with people

PsychodynamicPerspective

• Focus: How behavior is affected by unconscious drives and conflicts

• Behavior is explained through unconscious motivation and unresolved inner conflicts from one’s childhood.

• Modern version of psychoanalytic perspective (Sigmund Freud)

Evolution

• Darwin’s Theory of Evolution with the process of Natural Selection influenced Psychology.• The most adaptive traits will

survive due to natural selection

• Focused on how one’s environment might cause one to adapt physically, behaviorally & psychologically to insure the success of future generations.

Evolutionary Psychology

• Influenced by Darwin and the emphasis on innate, adaptive behavior patterns

• Combines aspects of biological, psychological, and social perspectives

• Behavior is explained by how the behavior may have helped our ancestors survive long enough to reproduce successfully.

Biological Psychology= the scientific study of the links between

biological (genetic, neural, hormonal) and psychological processes.

• Some biological psychologists call themselves– behavioral neuroscientists, – neuropsychologists, – behavior geneticists, – physiological psychologists, or – biopsychologists.

Cognitive Psychology

= the scientific study of all the mental activities associated with thinking, knowing, remembering, and communicating.

Evolutionary Psychology

= the study of the evolution of behavior and mind, using principles of natural selection.

Psychodynamic Psychology

= a branch of psychology that studies how unconscious drives and conflicts influence behavior, and uses that information to treat people with psychological disorders.

= the scientific study of how we think about, influence, and relate to one another.

Industrial-Organizational (I/O) Psychologists

= the application of psychological concepts and methods to optimizing human behavior in workplaces.

Human Factors Psychologists

= an I/O subfield that explores how people and machines interact and how machines and physical environments can be made safe and easy to use.

Counseling Psychology

= a branch of psychology that assists people with problems in living (often related to school, work, and marriage) and in achieving greater well-being.
