how people behave
Psychology describes
Philosophy
Psychology has its roots in...
behavior and mental processes
Psychology is defined as the study of?
how people will behave under certain circumstances
Psychology predicts
causes of behaviors
Psychology understands (explains)
Psychology
The science of behavior and mental processes
hypothesis
a statement that describes relationship between two or more things
statistics
an analysis of data
case study
an intensive examination of behavior/mental processing in a particular individual, group, or situation; in depth focus on all aspects of a single subject; subject may possess unusual or unique characteristics. no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions
Biological Psychologists
analyze biological factors involved in behavior and mental processes
evaluate
analyze data and draw conclusions
Behavior
any activity that can be observed, recorded, and measured (school psychologists are making use of PDAs to record observations of students in classrooms)
mean
average
Evolutionary Approach
behavior and mental processes of animals and humans is largely the result of natural selection (ex: mate selection-male and female)
Behavioral Approach
behavior is determined by learned habits that are a by-product of rewards and punishments
Empiricism
believe we were born as a blank slate; believe knowledge is ONLY gained through observance and EXPERIENCE
watson
believed learning is the most important cause of behavior
ethics
cannot be forced on participants, can't be forced to finish after you start, can be deception, cannot risk harmful things
measures of central tendency
central or middle point in data set
stronger the relationship
closer r gets to -1.0 or +1.0
Educational Psychologists
conduct research and develop theories about teaching and learning
operationalize
define in measurable terms the variables in the hypothesis
measure
design study and collect data; determine who are the "subjects"; determine procedures to be used in collecting the data
inferential statistics
determining whether results of research are due to luck or chance/represent truly significant findings
inferential statistics
draw conclusions about data (saying "this causes that")
Experimental Group
experiencing treatment condition (variable is present in this group)
descriptive statistics
frequency distribution, measures of central tendency, measures of variation
Biological Approach
genetics, electrical and chemical activity, and hormones are most important
reliability
getting similar results every time during experiments
frequency distribution
groups data into intervals
correlational method
helps us to predict, shows a relationship, used to determine whether two variables or measures are related (ex: ACT scores and college GPA; winter and depression) no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions, looks ONLY at TWO variables
high variability
high S.D.
Cognitive Approach
humans are info. processors and problem-solvers; actions are governed by thought and planning
eliminate it
if the # is not between -1 and +1 then...
Personality Psychologists
interested in what makes people unique/how behavior is affected by "personality traits"
Introspection
inward look; describing in detail the experience of feeling and seeing something
"psyche" and "logos" logos = "the study of" psyche = "soul"
literal meaning of psychology
low variability
low S.D.
Control Group
matched to be similar to experimental group except they don't receive experimental treatment
validity
measuring what you are intending to measure
median
middle most
mode
most often
Humanistic Approach
people strive to grow, develop, and reach their full potentials as humans
Scientific Method
procedures used to develop questions, accumulate evidence, and draw conclusions
1) naturalistic observation 2) survey method 3) case study 4) correlational method 5) experimental method
research methods in psychology
Experimental Method
researcher makes a change in one variable and then observes the effect of that change on another variable while holding other variables constant; random assignment; if differences between groups are found, variables other than independent variables cannot account for those differences; ONLY method that can identify cause and effect relationships; results cannot be generalized too broadly
report findings
scientific journals, newspapers, targeted groups (ex: National Education Association, Chamber of Commerce)
increases in one variable accompanied by increases in another variable
scores nearing +1.0
increases in one variable accompanied by decreases in another variable
scores nearing -1.0
variable
something that can occur with different values (ex: height, weight, ratings on a questionnaire)
School Psychologists
specialize in testing and diagnosing learning disabilities
measures of variation
spread or distribution of scores around the mean
hypothesis
statement about what you expect to happen if certain conditions are true (if/then format)
theory
statements that are designed to explain a phenomenon
inferential statistics
statistical analysis, correlation coefficient
skinner
studied operant conditioning, a learning process through which rewards and punishments shape, maintain, and change behavior
Clinical Psychologists
study and correct abnormal behavior and mental processes ***(MOST psychologists are this)***
Developmental Psychologists
study changes in behavior and mental processes that occur over a lifetime
I/O (Industrial/Organizational Psychologists)
study factors that affect workers and the organizations that employ them
Social Psychologists
study the ways people influence one another
descriptive statistics
summarizing and describing data
correlation coefficient
tells us direction and degree of relationship between two variables
Critical Thinking
the process of assessing claims and making judgments based on well-supported evidence
Philosophy
the rational investigation of the truths and principles of being, knowledge, or conduct
Culture
the sum of all the values, rules of behavior, forms of expression, religious beliefs, occupational choices, and the like among a group of people who share a common language and environment
Dependent Variable
the variable that concerns the responses the participants make ("then" part of hypothesis)
Independent Variable
the variable that the experimenter manipulates or changes ("if" part of a hypothesis)
variables
things that can "vary" or change in ways that are measurable
Cognitive Psychologists
thinking, learning, memory, problem-solving
Mental Processes
thoughts, feelings, memories, perceptions, beliefs
Community Psychologists
try to help stressful conditions (counseling) that lead to disorders
statistical analysis
used to compare two groups to see if they are truly different
survey method
using questionnaires/interviews to obtain info about attitudes, beliefs, opinions, and personality characteristics, give us descriptive info, no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions
Confounding Variable
variables that will interfere with data and affect the dependent variable if not controlled
naturalistic obersvation
watching, used to study how people or animals behave in their natural environments, no random assignment, no experimental treatments/conditions, cannot make cause and effect conclusions
the processes themselves
we observe the manifestation of mental processes, but NOT.....
ensures groups are the same from the start
what does random assignment to experimental or control groups do?
Eclectic
when you use more than 1 perspective to explain behavior and mental processing
Counseling Psychologists
work as mental health counselors and study causes and how to treat disorders
developmental psychology
Andrea is interested in the kinds of mental changes that take place in people between the ages of 45 and 65. Into which area of specialization in psychology does the research fall?
standard deviation
"average difference" between each score and the mean of the data set (score-mean=standard deviation)
James
"functionalism" - how and why the mind "functions" the way it does to allow us to live and adapt
Wundt and Titchener
"structuralism" - study the mind by breaking it down into its basic components or "structures"
Psychodynamic Approach
(Freud) unconscious processes and unresolved conflicts from past influence behavior and mental processes (ALWAYS deals with unconscious)
Collectivist Culture
(Japan and other parts of Asia) people tend to think of themselves as part of family or work groups; cooperative efforts aimed at advancing welfare of these groups is highly valued; fear of rejection by the group is common
Individualistic Culture
(North America and Western Europe) people tend to focus on and value personal rather than group goals and achievement; competitiveness, isolation
1) Individualistic 2) Collectivist
2 types of cultures
1. Descriptive Statistics 2. Inferential Statistics
2 types of statistics
1. Describe 2. Explain 3. Predict 4. Control
4 Goals of Psychology
5% level of probability
5 chances out of 100 that results occurred by luck/chance
