First formal laboratory in experimental psychology:

First formal laboratory in experimental psychology:

Germany.

Historically - Wundt's "method of introspection" (look into own mind)

Not a major method to study brain

Limitations of introspection:

• Assumes you know the contents of your mind (2-track mind)

Influenced by the person testing you

How can we describe the field of psychology today?

Various levels of explanation: for example, macro (society, culture), micro, individual

Found in theoretical orientations/perspectives

theoretical orientations/perspectives

preferred ways of answering questions about human behavior (how psychologists study something)

eclectic

wide variety

subfield

area of training, can get degree in.

60% of psychologists work in mental health.

Examples: Forensic (legal issues), pediatric (children in health care settings), human factors/engineering (build equipment to reduce human error), industrial/organizational I/O (business settings), clinical (mental health), counseling (problems of routine life adjustment)

variable

anything that varies (height, age, score)

operational definition

define variables in terms of how you actually measure them

correlation

a number that represents a relationship (has a value and direction)

Line up = positive correlation (1.0 correlation = a perfect positive), Line down = negative correlation (-1.0 correlation = a perfect negative), no/zero correlation = random dots

Limitations of correlational research:

"third variable problem" - only tells two things that are related, not why things are related

Who uses correlational research and why?

Medicine, psychology, and other disciplines use correlational research

Correlational Research is cheap and fast, so it is a good first step. Many ideas about relationships spring from correlational observations

Correlations allow you to predict

Sometimes you have look at "naturally occurring" variables because it is unethical or impossible to manipulate variables

experiments

Designed to determine causality

Control everything except one variable that you manipulate

independent variable

experimenter manipulates (free to vary)

dependent variable

outcome variable (dependent on what the researcher manipulates)

possible confound

anything that you can't control, so it influences study

Solution: double-blind studies

Examples of possible confound:

Hawthorne Effect: people tend to work harder and perform better when they know their being watched

General "subject expectation effect" and experiment effects: can alter experiments
