Quizplus · Accepted Answer

Attrition refers to the loss of participants in a study over time, which can lead to a smaller sample size and potentially biased results. This is different from developmental effects, which refer to changes in behavior or abilities that occur naturally over time. Cohort effects refer to differences between groups of participants based on the time period in which they were born or experienced significant life events. Infant determinism is not a recognized concept in psychology.
