Cross-sectional studies can be threatened by cohort effects, which refer to the fact that different age cohorts may have been exposed to different cultural, historical, or social factors that could influence their development, behaviors, and attitudes. This means that if researchers find differences between age groups, they cannot be sure whether these differences reflect true developmental changes or simply reflect cohort differences. Practice effects refer to the fact that participants may become more skilled or experienced with a task simply by performing it multiple times, whereas participant dropout refers to the fact that some individuals may drop out of a study before it is completed, which could bias the results. Sequential timing refers to the fact that different participants may be measured at different time points, which could affect the comparability of the data.
