Test 1 - I/O psych
construct validity
extent to which a test measures the underlying construct it claims to measure **think ACCURACY
concurrent validity
extent to which a test predicts a criterion that is measured at same time that the test was taken
trust
extent to which employees believe that fair and accurate appraisals have and will be made in their organization
inter-rater reliability
extent to which multiple judges/raters agree on ratings of a particular behavior or thing
external validity
extent to which results obtained generalized to/across other people, settings, times
predictive validity
extent to which scores obtained at one point in time predict criteria at some later time
parallel forms
extent to which two independent forms of a test are similar measures of the same construct
Internal validity
extent to which we can draw causal inferences about variables - are results due to IV? - control extraneous variables
social-psychological context
factors like the social, legal, and organizational cultures affect performance appraisal
quasi-experiments
field studies without random assignment or IV is not manipulated (naturally occurs)
D. Bruce V. Moore
first I/O PhD from carnegie tech PSU professor ad built strong I/O psych program
Army alpha and beta tests
group administered tests verbal & numerical ability, ability to follow directions, and knowledge of information does not measure IQ measure acculturation (test scores correlated with number of years living in USA)
what are competencies?
groups of KSA's that allow employees to perform specific functions
control
hold variables constant
most effective approach to job analysis
hybrid approach (combination of task and worker oriented)
Hawthorne studies
important in shaping ideas concerning how managers should treat workers - illumination study (impact of lights on productivity) - relay assembly (only researchers in room - no manager)
internal consistency reliability
indication of interrelatedness of items measuring the same construct
360 degree feedback
involves the use of ratings by subordinates, peers, supervisors, clients, and self
job specification is to people requirements as what is to task requirements
job description
what are the three main outcomes of "products" of job analysis?
job description, job evaluation, job specifications
what do we use to determine how much a particular job should pay
job evaluation
three main products of job analysis
job evaluation, job description, job specifications
Army Alpha and Beta Tests
mental ability tests used to select and classify army personnel during World War 1
principle 2
need better processes, not better people
principle 3
need the scientist-practitioner approach
observational methods
neither random assignment or manipulation
regression
one step beyond computing a correlation; allows us to predict one variable from other variables
job description
outcomes of job analysis
job specs
outcomes of job analysis
science
process for generating a body of knowledge - helps us describe, explain and predict human behavior at work
Job analysis
process of defining a job in terms of its component tasks or duties and the knowledge or skills required to perform them - task or major work behaviors - entry level KSAO's (knowledge, skills, abilities)
Hugo Munsterberg
psychology and industrial efficiency textbook
objective performance criteria involve the measurement of what aspects of job performance. Subjective performance criteria involve what of others.
quantifiable judgements/evaluations
Laboratory experiments
random assignment and manipulation of IV's are used to increase control
graphic rating scales
rate folks on amount/quality of trait or behavior
test-retest
reflects consistency over a test of time - also called stability coefficient
what do feedforward interviews focus on?
replace the traditional PA; focuses on employees strengths and aims to enhance the relationship between rater and ratee
halo error
result from raters tendency to use a global evaluation or a ratee in making dimension-specific ratings
true halo
resulting from accurate intercorrelations among dimensions
relationship between data and theory
science uses both
What is I/O Psychology?
scientific study of human behavior in organizations - psych theory to try to understand methods - to improve employee/org effectiveness, enhance desired workplace behaviors
SIOP
societal industrial organizational psychology - the professional association with which I/O psychologists affiliate
deduction
start with theory and propositions then collect data to test proportions then revise theory based on data
performance appraisals
systematic review and evaluation of the employees job performance and the delivery of performance feedback
field experiments
take advantage of realism for external validity - use random assignment and manipulation
measures of dispersion
tells how closely scores are grouped around the mean
a correlation coefficient of .72 means:
that the two variables have a positive linear relationship
reliability
the consistency or stability of a measure returns the same value under consistent conditions
Relevance
the degree to which the actual criterion relates to the ultimate criterion
KSAO's
the knowledge, skills, abilities, and other characteristics that are required for successful job performance
leniency
the leniency bias describes the situation where the manager tends to be more lenient than his or her peers, when rating employees
job analysis
the process of defining a job in terms of its major work behaviors and KSAO's needed
Halo
the rating error that results form either (1) a raters tendency to use his or her global evaluation of a ratee in making dimension-specific ratings for that ratee or (2) a raters unwillingness to discriminate between independent dimensions of a ratees performance
the concept of reliability refers to
the stability/consistency of measurement
organizational psychology
the subspecialty of I/O psychology that studies relationships among workers, supervisors, and subordinates is
describe the ultimate criterion
theoretical construct encompassing all performance aspects that define success on the job
industrial
topics associated with management of HR ex. job analysis, training, recruitment, selection, performance appraisal
organizational
topics associated with understanding/predicting behavior within org settings ex. socialization, motivation, work attitudes, stress
experimental designs
two critical issues concerning experimental method
dependent variable
variable of interest that we design our studies to asses - criterion/outcome/consequence
rating formats
various forms you can use to conduct appraisals
Founding fathers
walter dill scott hugo munsterberg yerkes
principle 1
workers need incentives to work harder
Primary Takeaway from Hawthorne Studies
- Employees performance is influenced by social factors and norms - organizational psychology emerged from these studies
what makes a good theory?
- Parsimony: does it explain a lot simply? (not too complex) - testability: is it verifiable by experimentation? - usefulness: lead to more research? - generativity: lead to more research?
Walter Dill Scott
- gave talk in Chicago on psychological aspects of advertising - student of Wundt - published the theory of advertising - first professor of applied psychology at carnegie tech (now carnegie mellon university)
hawthorne studies takeaways
-employee performance is influenced by social factors and norms - the O-side emerges as research and work focus on group processes, worker motivation
Criteria for criteria
1. Relevance 2. Reliability 3. Sensitivity 4. Practicality 5. Fairness
Birth of I/O
1901
how many scientific management principles are there
3
multi-source feedback
3 assumptions for 360 to work: 1. using multiple sources overcomes individual rater biases 2. employees have favorable reactions 3. multiple raters bring multiple viewpoints about the ratee which are valuable
given a correlation (r) of .20, what percentage of the criterion score variance (r^2) can be accounted for by the predictor?
4% of the variance in the criterion can be accounted for by the predictor
rater Biases
a common source of criterion contamination
job evaluation
a technique that attempts to determine the value or worth of particular jobs to organizations so that salaries can be set accordingly - an outcome of job analysis
job description
a written statement of what jobholders actually do, how they do it and why they do it - an outcome of job analysis
Scientist-practitioner model
an approach used to train I/O psychologist maintaining that because I/O psychologists are both generators and consumers of knowledge, training must be focused on both theory and application
scientist-practitioner model
an approach used to train I/O psychologists that is focused on both theory and application since I/O's are both generators and consumers of knowledge
job specifications
an outcome of job anaylsis delineating the KSAO's deemed necessary to perform a job
Independent Variable
anything that is systematically manipulated by the researcher - precursor/predictor/antecedent
tradeoff between external/internal validity?
as one goes up the other goes down
BARS
behaviorally anchored rating scale - a PA that uses behavioral descriptions for evaluations
Reactions Criteria
best indicator of viability of the PA system
Induction
collecting data until you have enough to develop a theory
validity coefficient
computed between predictor score and criterion score
performance management
continuous process of individual performance improvement
manipulation
controls IV's
experimental methods
controls the context and order of events = fewer confounds
content validity
degree to which a test covers a representative same of a quality being assessed
criterion-related validity
degree to which a test is a good predictor of attitudes, behavior, or performance has two approaches 1. predictive validity (extent to which scores obtained at one point in time predict criteria at some later time) 2. validity coefficient (computed between predictor score and criterion score
Yerkes
developed mental ability tests (army alpha and beta) used to select and classify army personnel
a comprehensive math achievement test only included questions about one aspect of math (algebra). what is this test lacking?
Content validity
You are an I/O psychologist correlating current IBM employees computer programming performance (as determined by their most recent performance appraisal) with their scores on a computer ability test. Your correlation is .50. You conclude:
High current validity
In an experiment, it is determined that only the independent variable caused changes in the dependent variable. Which type of validity did it have?
Internal Validity
