the scientific study of behavior and mental processes

Behavior

everything we do that can be directly observed

Mental processes

the thoughts, feelings, and motives that each of us experience privately

Critical thinking

the process of thinking deeply and actively, asking questions, and evaluating the evidence

Skeptical

Structuralism

focus on identifying the elemental parts or structures of the human mind (Wilhelm Wandt)

Functionalism

approach to mental processes, emphasizing the functions and purposes of the mind and behavior in the individual's adaption to the environment (William James)

Biological

focus on the body especially the brain and nervous system ex: when your heart races when you are afraid

Neuroscience

the scientific study of the structure, function, development, genetics, and biochemistry of the nervous system, emphasizing that the brain and the nervous system are central to understanding behavior, thought, and emotions.

Behavioral

emphasizes the scientific study of observable behavioral responses and their environmental determinants

B.F. Skinner

emphasized that psychology should be about what people do-- their actions and behavior-- and not the things that cannot be seen, such as feelings, thoughts, and goals.
believed that rewards and punishments determine our behavior

Psychodynamic

Humanistic

emphasizes a person's positive qualities, the capacity for positive growth, and the freedom to choose one's destiny

Cognitive

emphasizes the mental processes involved in knowing: how we direct our attention, perceive, remember, think, and solve problems

Evolutionary

approach that uses evolutionary ideas such as adaptation, reproduction, and natural selection as the basis for explaining specific human behaviors

Sociocultural

examines the influences of social and cultural environments on behavior

Descriptive Research

describing some phenomenon determining its basic dimensions and defining what this thing is, how often it occurs, and so on. Reveal important information about people's behavior and attitudes

Observation

one or more others to observe for accurate information

Case studies

an in-depth look at a single individual provide dramatic, detailed protrayais of people's lives

Correlational Research

tells us about the relationships between variables, and its purpose is to examine whether and how two variables change together

Longitudinal Designs

involves observing and measuring the same variables periodically over time

Random assignment

researchers assign participants to groups by chance.

Confederate

a person who is given a role to play in a study so it can be manipulated

Within-participant designs

the participants serve as their own control group

Quasi-Experimental designs

does not include random assignment of participants to a condition, either impossible or unethical

Validity

the soundness of the conclusions that a researcher draws from an experiment

External validity

the degree to which an experimental design actually reflects the real-world issues it is supposed to address

Internal validity

the degree to which changes in the dependent variable are due to the manipulation of the independent variable

Experimenter Bias

the influence of the experimenter's expectations on the outcome of research

Demend Characteristics

any aspects of a study that communicate to the participants how the experimenter wants them to behave

Systematic biases

called confounds

Research Participant Bias

in an experiment, the influence of participants' expectations, and of their thoughts on how they should behave

Placebo Effect

the situation where participants' expectations, rather than the experimental treatment, produce an experimental outcome

Placebo

a harmless substance that has no physiological effect

Naturalistic observation

the observation of behavior in a real-world setting ex: sporting events, work, shopping malls

Informed Consent

all participants must know what their participation will involve and what risk might develop

Confidentiality

researchers are responsible for keeping all of the date they gather anaonymous

Debriefing

after the study is completed, the researchers should inform the participants of its purpose and the methods they used

Deception

telling the participants beforehand can alter the participants' behavior and invalidate the data
