Griggs psychology chapter 1

Our observable behavior, such as speech and physical movement, and our internal mental processes, such as remembering.

The subset of a population that actually participates in a research study.

A description of the operations or procedures that a researcher uses to manipulate or measure a variable

The average extent that the scores vary from the mean for a distribution of scores

A depiction, in a table or figure, of the number of participants

The major explanatory focus is on how our mental processes, such as perception, memory and problem solving.

Our physical hardware is viewed as the major determiner of behavior and mental processing. Ex:genetics and evolution

The researcher studies an individual in depth over an extended period of time

A research perspective whose major explanatory focus is how external environmental event’s condition observable behavior

A statistical technique that results in a large number of studies on one experimental question into an overall conclusio

The sign of the coefficient indicates the type of correlation, positive or negative.

A control measure in which participants are randomly assigned to groups in order to equalize characteristics in an exp

Specifically focuses on the impact of other people and our cultures as the major determines of our behavior

A sampling technique that obtains a representative sample of population ensuring that each individual has a = oportunity

An explanation of a correlation between two variables in terms of another variable

A negative placebo effect due to the expectation of adverse consequences from receiving treatment

A control measure which participants know which participants are in the experimental and the control groups

Using questionnaires and interviews to collect information about the behavior belief and attitudes of certain groups

A direct relationship between two variables

The entire group of people that a researcher is studying

An inverse relationship between two variables

Average of All numbers

After learning about an outcome, to be overconfident in one’s ability to have predicted it.

The percentage of scores below a specific score in distribution of scores

Descriptive,correlational and experimental

Statistics that describe the results of a research study in a concise fashion

Naturalistic observation; where behavior is observed in its natural setting, without the researcher intervening

The biological perspective and the cognitive perspective focus on causes that stem from within us

An asymmetric frequency distribution in which are some unusual high score that distort the mean to be higher than median

Most frequent occurring number

A research study in which two variables are measured to determine if they are related

The difference between the highest and lowest scores in a distribution of scores

The group not exposed to the independent variable

In an experiment, the variable that is hypothesized to be affected by the independent variable and is measured by the ex

Any factor that can take on more than one value. Ex:age,height and grade point average

Used the most often because it allows the researcher to explore cause-effect relationships

In an experiment, the group exposed to the independent variable

In an experiment, the variable that is hypothesized cause and thus is manipulated by the experimenter

Visual depictions of correlational data in each data point represents the scores on the two variables for each participa

Middle number

An asymmetric frequency distribution in which there are some unusually low scores that distort the mean tobe less median

-the observer becomes part of the group being observed

Biological, cognitive, behavioral and sociocultural

A research method where the researcher manipulates one and more independent variables and measures

Statistical analyses that allow researchers to find the results of a study by determining the probability due to chance

The behavioral perspective and the sociocultural perspective focus on causes stem from outside us
