Job Performance and Individual Differences Flashcards
What is the schema of a data-driven approach
- Obtain existing measures of job performance
- Attempt to correlate several test results with job performance, or design a new test altogether
- Use statistical results to judge the best test
The data-driven approach is designed to answer the following questions:
- Which test best predicts job performance?
- Are cognitive or personality tests better predictors of job performance?
- Is my newly developed test better than the last?
Limitation of data-driven approach
It focuses purely on the tests’ statistical characteristics and lacks theoretical insight
Data-driven approach cannot answer questions like….
- Why does one test work better than another?
- What construct were the tests measuring?
- Could I expect the same result if a different test was used?
- What can I practically do to improve performance?
What are constructs (simple definition)?
Concepts
Definition of constructs
Hypothetical attributes or mechanisms that help explain and predict behavior in a theory
Characteristics of constructs
- They cannot be seen; only assumed to exist
- They must be grounded in theory
- There must be a valid evidence of their existence
Explain multidimensional constructs
- The higher-order factor (second-order factor) is defined by another layer of factors
- First order factor (subfactor/facet) is defined by observable variables
- The number of items deployed to measure a construct may vary.
What is the schema of a construct-oriented approach
- Use job analysis to define the nature of the job
- Hypothesize what are the constructs needed for an accurate prediction
- Choose or design a measure for the construct
- Different researchers may use different measures, but if they measure the same construct, the conclusion will be same
What are the benefits of a construct-oriented approach?
- Develops research that tests theories of human functioning
- It makes better tests due to higher construct validity
- Enables test-generic research
- Can detect and remove confounds
Definition of Personality
An individual’s stable and characteristic way of thinking, feeling, and behaving
Or chronic patterns of behavior
4 reasons why MBTI lacks validity
- Reliability
- Validity
- Mis-specified theory
- Incomplete theory of personality
2 ways how factorizing the complex human world into key concepts helps
- Provides standardized labels and definition
- Predict how certain factors typically affect each other
Definition of factor analysis
It tries to extract parts of all the measured variables that are commonly correlated
A good personality theory tries to…
Factorize as much of human characteristics as possible
Each factor in a personality theory is referred to as…
Personality trait
The existence of personality implies that…
Everyone is different to different extents, in similar ways
What does the lexical hypothesis in the Big 5 model of personality assume?
Important ways to describe people will eventually be captured in language
What are the five factors of general personality in Big 5 model of personality?
- Extraversion
- Agreeableness
- Conscientiousness
- Emotional stability (Opposit of neuroticism)
- Openness to experience
What is the HEXACO model?
The original factors of Big 5 personality model plus honesty/humility
Is the big 5 Model a data-driven model?
Yes
Definition of conscientiousness
A tendency for dedicated and disciplined pursuit of goal-directed accomplishments
What are the 2 subfactors under Conscientiousness?
- Industriousness
- Orderliness
Observable variables under industriousness
- Achievement striving
- Competence
- Self-discipline
Observable variables under orderliness
- Deliberation
- Dutifulness
- Order
