Abstract:
Four studies examined processing of in-group and out-group information with stimuli that are more complex than those used in previous crossed categorization studies. A diverse set of predictions is generated by previous theoretical work to account for how participants will integrate information stemming from multiple group memberships. Heuristic, threshold-based processing of information was supported over algebraic processing. Participants appeared to divide stimuli into "in-grouplike" and "out-grouplike" metacategories. However, the threshold at which this distinction was made, and whether it was based on in-group favoritism or out-group derogation, was influenced by the nature of the situation and the task participants performed. Advantages of crossed categorization research that moves beyond the traditional two-group model are discussed.

Two-Way ANOVA
The two-way ANOVA analysis initially begins by stating the null hypothesis that there is an interaction effect between the two factors of a dataset. This effect can be visualized using line segments formed by joining the means for...
Crossover Experiments
Crossover designs are performed even with smaller sample sizes since the samples can act as their controls. These are better than simple randomized trials since patients are exposed to all the treatments.
How Data are Classified: Categorical Data
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...
