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...

Area of Science:
- Cognitive Science
- Developmental Psychology
- Infant Cognition
Background:
- Decades of research have explored infant categorization using behavioral methods.
- Key findings illuminate the 'what' and 'when' of infant categorization abilities.
Purpose of the Study:
- To review principal findings in infant categorization over the past 30 years.
- To identify limitations in understanding the mechanisms and conceptual development of infant categorization.
- To propose future research directions for the field.
Main Methods:
- Review of behaviorally based experiments.
- Analysis of visual preference, habituation, object examining, sequential touching, and inductive generalization procedures.
- Critique of existing methodologies and interpretation of data.
Main Results:
- Significant progress in describing infant categorization behaviors.
- Persistent challenges in elucidating underlying mechanisms and concept development.
- Context-specific nature of infant categorization and lack of interpretive ground rules identified as key limitations.
Conclusions:
- Current research has not fully clarified the mechanisms of infant categorization or concept development.
- Interdisciplinary approaches integrating imaging and computational methods are recommended.
- Adopting new methodologies can enhance understanding of infant cognitive processes.
