Flashcards in Research Design, Stats, Tests, And Measurements Deck (27):
What did Kulpe believe?
Believed, unlike Wundt, that there could be image less thoughts.
What was the purpose of the Binet-Simon test?
To determine which French children were not intelligent enough to benefit from regular schooling. The concept of mental age as also developed.
What is the more recent form of the IQ test?
Stanford-Binet intelligence test.
Who founded the first psych lab?
What is a noon equivalent group design?
When the control group is not necessarily similar to the experimental group (think studies in education).
What is the Hawthorne effect?
Effect that being observed has on behaviour.
What would happen if you converted every score into a z score?
The mean will be zero and the SD 1.
What is the mean and SD of T scores?
What is a correlation coefficient?
Measures to what extent your can predict the value of one variable with a second variable. Graphically represented by scatter plots.
What are Type I and Type II errors?
Type I - Rejecting a true null hypothesis (chances are same as criterion of significance)
Type II - Accepting a false null hypothesis (chances are Beta)
What information can you ascertain from an ANOVA?
F-ratio which tells us how much groups differ from each other by between and within group estimates (close to one if there is no significance), interaction effects (effect of an IV is not consistent across all levels of other IV).
When would you use a chi square test?
With nominal/categorical data.
What is the difference between norm- and domain-referenced testing?
Norm: assessing performance in relation to peers/standardized scores (problem - the population often changes rendering standardization invalid).
Domain: assessing mastery if a specific subject (driving test)
What is reliability?
Extent to which a test is dependable, reproducible, and consistent.
In what three ways can we measure a test's reliability?
Test-retest method, alternate form method, split-half reliability.
What are the different types of validity (7)?
Content (coverage of desired skill), face (does it seem to measure what it should), criterion (can it predict scores on similar tests), construct (fit in theoretical framework), predictive (predict future performance), convergent/divergent (correlations with other studies).
Is validity a precondition for reliability?
Not necessarily - without reliability there is no validity, but there can be validity without reliability.
What is the difference between an aptitude and an achievement test?
Aptitude: predict what one can accomplish with training
Achievement: assess current skills dan knowledge.
What does an IQ of 100 signify?
That a person's mental age is equivalent to their chronological age.
What is the difference between a ratio and deviation IQ?
Deviation: performance as it relates to others of your age group
What kinds of tests did Weschler create?
Tests for preschoolers, school aged children (5-16), and adults (16+) consisting mainly of verbal and performance scales.
What did Hathaway and McKinley use to develop the MMPI?
The empirical criterion keying approach - they retained all questions that differentiated between patient and non patient populations. Then they formed categories based on how differently diagnosed patients answered.
Which other personality inventory was based on the MMPI?
The California Psychological Inventory - this is especially for high school and college students.
What is the Thematic Apperception Test?
20 pictures of images that the test taker has to tell a story about, developed by Morgan and Murray.
What are the Blacky pictures supposed to represent?
12 pictures supposed to correspond with different stages of psychosexual development.
What is the Barnum effect?
Tendency to approve of the interpretation one gives of our personality (horoscopes).
