Definition:
consists of similar subjects who do not receive the special treatment given to the experimental group
Definition:
Occurs when participants’ expectations lead them to experience some change even though they receive empty, fake, or ineffectual treatment
Definition:
are the persons or animals whose behavior is systematically observed in a study
What is scientific, reducing bias and error in measurement.
Name the goals and characteristics of a research method.
What is control; the placebo effect
Definition:
consists of the subjects who receive some special treatment in regard to the independent variable
Definition:
is a research strategy in which subjects do not know whether they are in the experimental or control groups
Definition:
are any measurable conditions, events, characteristics, or behaviors that are controlled or observed in a study
What is variables?
Correlational method is used for describing relations between two or more variables. Relations could be expressed as positive/negative strong/ weak. Hence coefficient of correlation could be +1, 0, -1 and all values between 0 and 1.
Describe correlational method briefly. When do we use it?
Definition:
is the variable that is thought to be affected by manipulation of the independent variable
Definition:
which occurs when someone’s overall evaluation of a person, object, or institution spills over to influence more specific ratings
experiment, correlational method, naturalistic observation, case study, survey.
Name at least 3 different research methods psychology employs to study psychological phenomena.
1. formulate a testable hypothesis, 2. select the method and design the study, 3. collect the data, 4. analyze the data and draw conclusions, 5. report the findings
Name the steps of scientific method. and describe them briefly.
Definition:
is a condition or event that an experimenter varies in order to see its impact on another variable
Definition:
occurs when a researcher’s expectations or preferences about the outcome of a study influence the results obtained
Definition:
is a research method in which the investigator manipulates a variable under carefully controlled conditions and observes whether any changes occur in a second variable as a result
+1 is more than 0.
+ means positive relation (variables go the same way)
- means negative relation (variables go the opposite way)
-.20; +.40, -.60, +.80
How do we measure the strength of the relationship? What does the sign (plus, minus) tell us?
Rank the strength of these correlation coefficients: -.60; + -40, +.80, -.20-
Definition:
are any variables other than the independent variable that seem likely to influence the dependent variable in a specific study
Definition:
is a research strategy in which neither subjects nor experimenters know which subjects are in the experimental or control groups
Independent and dependent variable, random assignment, experimental and control groups.
Name the characteristics of experiment.
which is a tendency to give socially approved answers to questions about oneself
courtesy bias or social desirability bias
