Chapter 1 Introduction to Psychology, Chapter 1 History and Modern Perspectives, Chapter 1 Research
Psychology
the scientific study of behavior and mental processes
Behavior
Observable; peoples actions and reactions to different situations.
Mental Processes
grouped into 2 categories; cognition and emotion
Cognition
thinking and reasoning
Emotion
feeling
Research Psychologists
discover information about behavior and mental processes (behind the scenes)
Applied Psychologists
use basic information discovered through basic research to help people (apply)
Subfields
interrelated specialty areas; affected by human diversity, especially by age, gender, race and ethnicity
Positive Psychology
the focus on the things that make life most worth living (happiness, optimism, and resilience)
Cognitive Psychologists
study the basic mental processes such as sensation and perception, learning and memory, judgment, decision-making, etc… (thought or cognition)
Biological Psychologists
study topics such as the relationship of genes and brain chemistry to mental disorders, how brain cells communicate with each other when forming memories, etc… ( analyze the biological factors influencing behavior and mental processes)
Personality Psychologists
study individuality ( the unique features of each person); personality traits, fingerprints, etc
Developmental Psychologists
study and describe how mental processes change over the life span in order to understand their cause and effects. (development of thought, friendship patterns, parenting styles); study how behavior and mental processes change over time.
Quantitative Psychologists
Develop and use statistical tools to analyze vast amounts of info generated by research results from all of psychology’s subfields
Clinical, Counseling, and Community Psychologists
seek access, understand, modify, and prevent behavior disorders; help troubled people get over disorders
Educational Psychologists
study methods in which instructors teach and students learn and who applies their results to improve those methods; more learning based
School Psychologists
test cognitive abilities, diagnose students academic problems, and set up programs to improve students’ achievement; more community based
Social Psychologists
study the ways that people influence each other; study how people influence each others behaviors and attitudes (especially in group settings)
Industrial and Organizational Psychologists
examine factors that contribute to peoples performance in the workplace; foster positive organizational behavior
Health Psychologists
study the effects of behavior on health and the impact of illness on behavior and emotion
Forensic Psychologists
involved in many aspects of psychology and law
Engineering Psychologists
study and try to improve the relationship between human beings and computers/ other machines that they use.
Environmental Psychologists
study the relationship between peoples physical environment and their behavior
Philosophy
what is the purpose of things and why we are here
Rene Des Cartes, John Locke
Tabula Rasa
Science
systematic study of the world around us through observation, experimentation, and the testing of theories using evidence
Scientific revolution (1600s)
Galileo Galilei, Issac Newton
Empiricism
idea in which knowledge comes through measurable, observable, and testable information that we can detect with our senses
(show me the evidence)
Structuralism
defining the structure, - the what- of consciousness; what are the basic building blocks that exist first that then allow for all levels of thought; ( consciousness)
Introspection
personal observation of our own thoughts, feelings, and behaviors; ignore what the objective is, instead try to describe your own consciousness experience with it
Functionalism
idea that our conscious thoughts exist to serve a purpose, of helping us take in information from the world around us so that we might adapt to changes in our environment to survive
William James
Psychoanalytic Theory
our behavior is deeply influenced by our unconscious thoughts, impulses and desires
Sigmund Freud (Think of an iceberg)
Gestalt Psychology
the combination of all that we consciously experience is lost if we try to divide it into its component parts
Fill in the blanks
Max Wertheimer
Behaviorism
psychologists should only be concerned with observable behavior, not thoughts
Concrete facts in front of you
John Watson, B.F. Skinner
Theory
an explanation that narrows the focus of an investigation; provides a framework for how to interpret what we observe.
Biological/ Neuroscience Approach
mental processes and behaviors are the result of biological processes
Evolutionary Approach
mental processes and behaviors can be explained by what evolutionary value those ways of being hold or held in our ancestral past.
Psychodynamic Approach
thoughts and behaviors are interpreted by our beliefs and interpretations outside of our conscious awareness until they are addressed on a conscious level.
Behavioral Approach
Behavior is primarily influenced by learning from observable outcomes
Cognitive Approach
behavior is shaped by the ways we take in, perceive, interpret, categorize, and retrieve information using our brain.
Humanistic Approach
behavior is determined by what choices we perceive to be available to us and our respected, individualized ideas.
Sociocultural/ Ecological Approach
behavior is shaped by factors related to our socio-cultural demographic factors such as race, gender, ethnicity, class, etc…
Eclecticism - Contemporary Approach
most psychologists take ideas from multiple perspectives to answer questions about behavior and mental processes.
Critical Thinking
process of assessing claims and making judgements based on well-supported evidence.
The Scientific Method
observe/ identify the problem → ask a question → predict/ hypothesize → collect and analyze data → draw conclusions
Theory
set of related ideas or information that is organized in such a way that we can use it to explain or predict behavior (ideas that guide predictions).
Hypothesis
a prediction based on a theory that can be tested in measurable terms.
Descriptive Research
looking to report on what is naturally occurring without my influence.
Experimental Research
looking to see what happens under different conditions that I can influence.
Naturalistic Observation
Key Idea: observing in a natural environment
Advantages: see behavior as it really is: is useful for stressful situations
Disadvantages: no control; no data on reasons of behavior, only can describe
Systematic Observation
Key Idea: structure an environment in which you will observe patients
Advantage: more control over context; can narrow down potential casual variables
Disadvantages: not a natural environment → affects behavior
Case Studies
Key Idea: study one or few individuals intensively
Advantage: rich data; opportunity to study rare conditions or situations
Disadvantage: no ability to generalize findings to others
Surveys
Key Idea: asking the same questions of many participants via paper-and-pencil or online
Advantage: can get lots of data relatively quickly
Disadvantage: cannot follow up; no explanation for answers
Interviews
Key Idea: asking the same questions of many participants via conversation and systematic questions
Advantages: can get detailed information; cam ask follow up questions
Disadvantages: time-consuming; other logistical challenges
Correlational Research
Key Idea: examines the relationship between two or more variables
Variable: anything that you can observe or measures
Important: correlations do not imply that one variable causes the other
Sign
Positive: variables move in the same direction
(i.e. height and shoe size)
Negative: variables move in opposite directions
(i.e. class skipping and GPA)
Magnitude
Size of number
Zero: no relation'
1 or -1: perfect relation
closer to either end: stronger
closer to middle: weaker
The Third Variable Problem
the simultaneous influence of a third (unmeasured) factor on the two variables under study
Correlational Research:
Key Idea: determining if two or more things seem to be related to each other
Advantage: can collect data from large number of patients
Disadvantage: cannot prove that one variable causes a change in the other
Experimental Research
Goal: to establish the causes and effects of behavior
experimental methods
conditions
controls
compare outcomes
Experimentation (cause-effect)
Key Idea: manipulate one variable and observe on outcome variables
hold other variables constant as much as possible; control and random assignment
Independent Variable
what you manipulate, what conditions you set (treatment vs not)
Dependent Variable
what you measure (outcome variable)
Experimenter Bias
when a researcher unintentionally influences participants to respond in a particular way
unintentionally communicating expectations) [also called the observer expectancy effect]
Confirmation Bias
tendency to interpret evidence as supporting ones prior beliefs; also the tendency to look only for evidence that supports ones beliefs (and ignore the other evidence)
Sampling Bias
choosing people to participate in a study in ways that might influence the result
(i.e. only choosing from one social group)
Placebo Effect
participants expectations influence their performance in a study
Self-Fulfilling Prophecy
if we believe something about ourselves ( or perceive that others believe things about us), then we will act to fulfill that expectation
Double Blind Research Design
make the experimenter and participants unaware of who is getting the treatment or control condition
Placebo
giving a “fake treatment” in order that participants (and experimenter) dont know who gets the actual treatment
(i.e. drug being tested vs sugar pill)
Random Sampling
choosing people for a study in ways that minimize sampling bias; random selection ensure that people (and their characteristics) are more evenly distribute across experimental and control groups
