AP Psych Chapters 1 and 2

Psychology

Scientific study of behavior and metal processes

Critical thinking

Process of reflecting deeply and actively, asking questions, and evaluating the evidence

Skepticism

Challenge supported facts; distinction between science and pseudoscience

Empirical method

Gaining knowledge through the observation of events, the collection of data, and logical reasoning; seeing things as they are and not what we want them to be

Curiosity

Want to know what and why; big questions

Sigmund freud

Believed human behavior is caused by dark, unpleasant, unconscious impulses clamoring for expression

Positive psychology

Branch of psychology that focuses on human strengths

Philosophy

Rational investigation of the underlying principles of being and knowledge

Wilhelm Wundt

Integrated philosophy and science to create psychology

Structuralism (Wundt)

Discovering basic elements of mental processes

Introspection

Looking inside our own minds, by focusing on our own thoughts

William James

Brought psychology to America; what is the mind for

Functionalism (James)

Functions and purposes of the mind and behavior in ones adaption to the environment

Charles Darwin

On the origin of species

Natural selection

Evolutionary process in which organisms that are better adapted to their environment will survive and produce offspring

The biological approach

Examining behavior and mental processes by focusing on the body, primarily the brain and nervous system

The behavioral approach

Scientific study of observable behavioral responses and their environmental determinants (not feelings but actions)

The Psychodynamic approach

Unconscious thought; conflict between biological drives, society's demand, and childhood family experiences

Psychoanalysis

Unlocking a persons unconscious by talking about childhood memories, thoughts, dreams, and feelings

The humanistic approach

Emphasizes a persons positive qualities, capacity for positive growth, and the freedom to choose ones destiny

Altruism

Unselfish concern for other people's well being

The cognitive approach

The mental processes involved in knowing; how we direct our attention, perceive, remember, and solve problems

The Evolutionary approach

Uses idea like adaption, reproduction, and natural selection to explain specific human behaviors

The sociocultural approach

Examines the ways in which social and cultural environments influence behavior

Theory

Broad idea or set of closely related ideas that attempts to explain observations

Hypothesis

Educated guess that derives logically from a theory

Prediction

Specific expectation for the outcome of a study

Empirical method

Gaining knowledge by observing objective evidence

Variable

Anything that can change (what scientists study)

Operational definition

Provides an objective description of how a variable is going to be measured and observed in a particular study

Direct replication

Doing the study precisely as it was done originally

Conceptual replication

Doing the study with different methods or samples

Meta- analysis

Statistical procedure that summarizes a large body of evidence from the research literature on a particular topic

Descriptive research

Describing some phenomenon, determining its basic dimensions, and defining what it is, how often it occurs, and so on

Survey

Questionnaire that presents a standard set of questions to obtain ones beliefs on a topic

Case study or history

In depth look at an individual

Correlational research

Tells us about the relationship between two variable (change together)

Correlational coefficient

Numerical value that shows the degree of relation between 2 variable (r)

Third variable pattern

Another variable that hasn't been measured for accounts for the relationship between 2 others (confound)

Cross sectional design

Type of correlation study in which variable are measured at a single point in time

Quasi experimental

Tested comes with the independent variable

Experience sampling method

Using daily reports to track experiences in ones natural settings

Event contingent responding

Report after each time one engages in a particular activity

Longitudal design

Obtaining measures of the variable of interest in waves over time

Experiment

Carefully regulated procedure in which the researcher manipulates one of more variable that are believed to influence some other variable

Independent variable

Manipulated experimental factor (cause)

Dependent variable

The variable that may change due to the manipulations of the independent variable (effect)

Confederate

A person who is given a role to play in a study so that the social context can be manipulated

Experimental group

Participants in an experiment who are exposed to the change

Control group

As much like the experimental group when treated except not exposed to the change

Validity

Soundness of conclusions that a researcher draws from an experiment

External validity

The degree to which an experimental design actually reflects the real world issue it addresses

Internal validity

The degree to which the dependent variable changes due to the independent variable

Experimenter bias

The experimenters expectations influence the outcome of the research

Demand characteristics

Any aspect of a study that communicates to participants how the experimenter wants them to behave

Research participant bias

The behavior of research participants during the experiment is influenced by how they think they are supposed to behave

Placebo effect

When participants expectations produce a particular outcome

Placebo

Harmless substance that has no physiological effect

Double blind experiment

The experimenter and the participants aren't aware of who is in the experimental or control group until the results are calculated

Population

The entire group about which the investigator wants to draw conclusion

Sample

The sunset of the population chosen by the investigator for study

Random sample

Gives every member of the population an equal chance of being selected

Naturalistic observation

Viewing behavior in a real world setting

Statistics

Mathematical methods for reporting data

Descriptive statistics

Mathematical procedures researchers have developed to describe and summarize sets of data in a meaningful way

Measure of central tendency

Single number that indicates the overall characteristics of a set of data

Mean

Average

Median

The middle score when ranked highest to lowest

Mode

Occurs most often in a data set

Range

The distance between the highest and lowest scores

Standard deviation

Measures how much scores vary, on avg, around the mean of a sample

Inferential sample

The mathematical methods used to indicate whether the data sufficiently supports a research hypothesis

Informed consent

All participants must know what their participation involves and what risks are possible

Confidentiality

Researchers are responsible for keeping all the data about someone secret or anonymous

Debriefing

After the research is completed the participants must be told it's purpose and methods

Deception

Can lie about purpose of study beforehand but cannot use a lie that will harm the participants
