- ( babies and rats)
7 modern perspectives in psychology
- Psychodynamic
- Behavioral
- Humanistic
- Cognitive
- Sociocultural
- Biopsychological
- Evolutionary
Psychodynamic perspective
- focus on unconscious, early development
- less emphasis on sex
- more emphasis on self
Behavioral Perspective
- B.F. Skinner
- operant conditioning
- Behavioral responses that are followed by pleasurable consequences are reinforced (crying child gets mothers attention)
Humanistic Perspective
- people have freedom to choose their own destiny
Cognitive perspective
- memory, intelligence, perception, problem-solving, learning
Cognitive neuroscience
- study of physical changes in brain and nervous system during thinking
Sociocultural perspective
- focus on relationship between social behavior and culture
- thinking and behavior seem as product of learning and shaping within family, social group, culture
Biopsychological Perspective
- Attributes human/Animal behavior to biological events (e.g. genetic influences, hormones, activity of nervous system)
Evolutionary Perspective
- focus on biological bases of universal mental characteristics that all humans share

The Scientific Approach
- Perceiving the question
- Forming a hypothesis
- Testing your hypothesis
- Drawing conclusions
- Report your results
Descriptive Methods
- Naturalistic observation
- watching in natural environment; realistic - Laboratory observation
- controlled situation; artificial behavior
Case studies
- Detailed investigation of one subject
- tremendous amount of info; but cannot be applied to other cases
Surveys
- Ask questions to large groups that represent sample of population of interest
- get large amount of data +
- May not always get truth from respondents
Correlations
A measure of relationships between to variables
- positive: variable related in same direction
- negative: variables relatives in opposite direction
Dependent & independent variable
Dependent:
- exposed or not
Independent:
- manipulated by experimenter
Correlation Coefficient
- number that represents strength and direction of relationship between two variables
Experimenter Effect
- experimenter’s expectations unintentionally influence results
Single-Blind Study
Subjects do not know if they are in experimental or control group
Double-Blind Study
Neither experimenter not subjects know if they’re in control or experimental group
4 Goals of Psychology
- Describe
- Explain
- Predict
- Control
Selection
- random selection of a sample from population of interest
Operationalization
Names steps/procedures used to control/measure variables in experiment
Experimental Group
Gets independent variable/experimental manipulation
Control Group
Receives no treatment/treatment that should not have an effect
Ethical Guidelines for doing research with people
- Protection of rights; well-being of participants
- Informed consent
- Deception must be justified (Debriefing)
- Right to withdraw anytime
- Protection from harm
- Debriefing participants at end of study
- Data must remain confidential
- Correcting any undesirable consequences that may result
Animal Research
- Why? Answers questions we could never answer with human research
- easier to control animals, possibly to dangerous for humans
- shorter lives, easier to study long-term effects
- avoid unnecessary pain/suffering
- only about 7% of psych. studies
Critical Thinking
Making reasoned judgements about claims
- Very few “truths” that do not need to be subjected to testing - everything’s needs evidence
- All evidence is not equal in quality
- Authority does not make somebody’s claims true
- Open mind requires
First psychology lab
Wilhelm Wundt in Leipzig, Deutschland
