Chapter 13 Flashcards
(18 cards)
a developmental design where a single sample of participants is followed over time and tested at different ages
Longitudinal design
each participant experiences all lvls of variable
w/in subjects variable
occurs when participants choose not to complete a study
attrition/mortality
occur when participants are tested more than once in a study w/early testing affecting later testing
testing effect
each participant experiences only one lvl of the IV
Between-subjects variable
a developmental design where multiple samples of participants of different ages are tested at once
cross-sectional design
a confound that can occur in cross. designs due to different experiences that different generations have
generation/cohort effects
a hybrid of cross. and long.
cohort-sequential design
a developmental design where multiple samples of participants of different ages are followed over time and tested at different ages
cohort-sequential design
Long. sources of bias
testing effect, mortality/attrition
Advantages of Long.
they’re their own control group, no group differences, run fewer kids.
cross-sectional sources of bias
cohort/generation effects
are experiments conducted w/one or fe participants to better understand the behavior of those individuals
small n designs
2 types of small n design
discrete trials design
baseline design
w/in subject experiment w/ a few individuals; designed to study basic “laws” of behavior
discrete trials
historical significant- Ebbinghaus tested himself, over memory and forgetting= classic ebbinghaus forgetting curve
discrete trials
experimental or quasi-experiment done on an individual or small group of similar individuals to examine effects of treatment or undesirable behavior
baseline designs
measure baseline behavior, given treatment, measure baseline again
A-B-A/ Reversal Design
