1. History, Approaches, Methods (Ch 1 & 2)
1.1 History of psychology
- What is Psychology?
- Pysche: mind, spirit, soul
- Ology: study of
- Psychology is the scientific study of human behavior and mental processes
- Structuralism
- Wilhelm Wundt
- First Psychology Lab in Leipzig, Germany in 1879
- Ideas of Structuralism
- Consciousness was made up of basic elements that were combined in different ways to produce perceptions
- Discover the basic elements of mental experiences
- Introspection
- Looking inwards to understand what is involved
- Wilhelm Wundt
- Functionalism
- Lead by William James
- Less interested in what made up mental experiences
- More interested in the processes or the functions of the human condition
- Consciousness helped people and animals to adjust to their environments
1.2. Psychological Approaches
- Biological approach
- Physiological and biochemical explanation of behavior
- Genes, neurotransmitters, neurochemicals
- Behavioral approach
- Ideas
- Learned responses to predictable patterns of external stimuli
- People's behaviour is based on the environment
- Classical conditioning (Ivan Pavlov)
- Operant conditioning (BF Skinner)
- How rewards and punishments affect behaviors
- Ideas
- Psychodynamic approach (Sigmund Freud)
- Ideas
- Unmet needs/unresolved conflicts from childhood determine personality
- Behavior as a result of unconscious, attachment and interpersonal connection
- Parts of psyche
- Id: I want it, and I want it now
- Ego:Moderator between id and superego. Reality Principle
- Superego: Moral
- Defense mechanisms
- Sexual and aggressive urges drive behavior, thoughts and feelings
- Ideas
- Cognitive approach
- In reaction to behaviorism (focused on observable events)
- Behavior as a result of “expectations”, “feelings” and “thoughts”
- Study problem solving, attention, memory and other thought processes
- Humanistic approach
- Ideas
- Developed in reaction to Behaviorist and Psychodynamic models
- People are motivated by desire for growth and development
- We have free will, and we are motivated to grow
- Abraham Maslow
- Self actualization
- Hierarchy of Needs
- Carl Rogers
- People are basically good
- Driven by unconditional positive regard
- Ideas
1.3. Research Methods
- Experimental
- Cause and effect relationship between two or more variables
- Types of variables
- Independent variable
- The variable being manipulated
- The “cause"
- Dependent variable
- The variable being measured for change
- The “effect”
- Independent variable
- Groups
- Experimental group
- Exposed to the “cause”
- Receives the independent variable
- Control group
- Not exposed to the “cause”
- Receives no treatment or some treatment that should have no effect
- Experimental group
- Methods
- Random Assignment
- Randomly choose who goes into each group
- Decrease bias
- Blind and Double Blind Study
- Neither party knows what they are receiving
- Leads to a more pure research study
- Placebo and Placebo Effect
- The sheer belief that I'm taking a medicine will change people's state of mind
- Random Assignment
- Clinical
- Case studies
- Freud used this method to develop psychoanalytic theory
- Hard to apply to a boader population
- Naturalistic observation
- Observe the behaviours of our subjects in a naturalistic environment
- Agreement among observers
- Clinical interviews
- Inter-rater reliability
- Case studies
- Correlational
- Ideas
- How two variables relate to one another
- No manipulation of variables
- Does NOT measure cause and effect
- Correlation Coefficient
- A number from -1 to 1
- Positive Correlation: Correlation Coefficient > 0
- Negative Correlation: Correlation Coefficient < 0
- Ideas
- Surveys
- Self-reporting surveys: Subject to bias
1.4. Ethics in Research
- Participants must be treated morally and respectfully
- Clearly state the purpose, duration and process of study
- Any possible harm or adverse effects should be disclosed
