Mid-Term study guide Flashcards
Industrial-organizational (I-O) psychology
The application of psychological principles, theory, and research to the work setting.
Society for Industrial and Organizational Psychology (SIOP)
An association to which many I-O psychologists, both practitioners and researchers, belong. Designated as Division 14 of the American Psychological Association (APA)
Personnel psychology
field of psychology that addresses issues such as recruitment, selection, training, preformance appraisal, promotion, transfer, and termination
Human Resources Management (HRM)
Practices such as recruitment, selection, retention, training, and development of people (human resources) in order to achieve individual and organizational goals.
Organizational psychology
Field of psychology that combines research from social psychology and organizational behavior and addresses the emotional and motivational side of work.
Human engineering or human factors psychology
the study of the capacities and limitations of humans with respect to a particular environment
Scientist-practitioner model
A model that uses scientific tools and research in the practice of I-O psychology
TIP (The Industrial-Organizational Psychologist)
Quarterly newsletter published by the Society for Industrial and Organizational Psychology: provides I-O psychologists and those interested in I-O psychology with the latest relevant information about the field
Telecommuting
Accomplishing work tasks from a distant location using electronic communication media
Virtual team
Team that has widely dispersed members working together towards a common goal and linked through computers and other technology
Title VII of Civil Rights Act of 1964
Federal legislation that prohibits employment discrimination on the basis of race, color, religion, sex, or national, origin, which define what are know as protective groups. Prohibits not only intentional discrimination but also practices that have the unintentional effect of discrimination against individuals because of their race, color, national origin, religion, or sex
American Psychological Association (APA)
The major professional organization for psychologists of all kinds in the United States.
Experimental design
Participants are randomly assigned to different conditions
Quasi-experimental design
Participants are assigned to different conditions, but random assignment to conditions is not possible
Nonexperimental design
Does not include any “treatment” or assignment to different conditions.
Observation design
The researcher observes employee behavior and systematically records what is observed
Survey design
Research strategy in which participants are asked to complete a questionnaire or survey
Quantitative methods
Rely on tests, rating scales, questionnaires, and physiological measures and yield numerical results
Qualitative methods
Rely on observations, interviews, case studies, and analysis of diaries or written documents and produce flow diagrams and narrative descriptions of events or processes
Triangulation
Approach in which researchers seek converging information from different sources
Experimental control
Characteristic of research in which possible confounding influences that might make results less reliable or harder to interpret are eliminated: often easier to establish in laboratory studies that in field studies
Statistical control
Using statistical techniques to control for the influence of certain variables. Such control allows researchers to concentrate exclusively on the primary relationships of interest.
Descriptive statistics
Statistics that summarize, organize, and describe a sample of data
Measure of Central Tendency
Statistics that indicates where the center of a distribution is located. Mean, median, and mode are measures of central tendency
Variability
The extent to which scores in a distribution vary
Skew
The extent to which scores in a distribution are lopsided or tend to fall on the left or right side of the distribution
mean
The arithmetic average of the scores in a distribution: obtained by summing all of the scores in a distribution and dividing by the sample size
Mode
The most common or frequently occurring score in a distribution
Median
The middle score in the distribution
Inferential statistics
Statistics used to aid the researcher in testing hypotheses and making inferences from sample data to a larger sample or population
Statistical Significance
Indicates that the probability of the observed statistic is less than the stated significance level adopted by the researcher (commonly p<.05). A statistically significant finding indicates that the results found are unlikely to have occurred by chance, and thus the null hypothesis (hypothesis of no effect) is rejected
Statistical power
the likelihood of finding a statistically significant difference when a true difference exists
Correlation coefficient
Statistic assessing the bivariate, linear association between two variables. Provides information about both the magnitude (numerical value) and the direction (+ or -) of the relationship between two variables
Regression line
Straight line that best “fits” the scatter plot and describes the relationship between the variables in the graph; can also be presented as an equation that specifies where the line intersects the vertical axis and what the angle or slope of the line is.
Linear
Relationship between two variables that can be depicted by a straight line
Nonlinear
Relationship between two variables that cannot be depicted by a straight line; sometimes called “curvilinear” and most easily identified by examining a scatter plot
Meta-analysis
statistical method for combining and analyzing the results from many studies to draw a general conclusion about relationships among variables.
Reliability
consistency or stability of a measure
Validity
The accuracy of inferences made based on test or performance data; also addresses whether a measure accurately and completely represents what was intended to be measured.
Test-retest reliability
A type of reliability calculated by correlating measurements taken at the time 1 with measurements taken at time 2
Equivalent forms reliability
a type of reliability calculated by correlating measurements from a sample of individuals who complete two different forms of the same test
Internal consistency
form of reliability that assesses how consistently the items of a test measure a single construct; affected by the number of items in the test and the correlations among the test items
Generalizability Theory
A sophisticated approach to the question of reliability that simultaneously considers all types of error in reliability estimates (e.g., test-retest, equivalent forms, and internal consistency).
Predictor
The test chosen to assess attributes identified as important for successful job performance
Criterion
An outcome variable that describes important aspects or demands of the job; the variable that we predict when evaluating the validity of a predictor
Criterion-related validity
Validity approached that is demonstrated by correlating a test score with a performance measure; improves researcher’s confidence in the inference that people with higher test scores have higher performance
Validity coefficient
correlation coefficient between a test score (predictor) and a performance measure (criterion)
Predictive validity design
Criterion-related validity design in which there is a time lag between collection of the test data and the criterion data
Concurrent validity design
Criterion-related validity design in which there is a time lag between collection of the test data and the criterion data
Content-related validation design
A design that demonstrates that the content of the selection produce represents an adequate sample of important work behaviors and activities and/or worker KSAOs defined by the job analysis
