    In cognitive psychology, classification and categorization are essential processes that help individuals make sense of the world by organizing information and making decisions based on past experiences. These processes are closely related to how the brain perceives, interprets, and responds to patterns in the environment.

    • 12.1: Approaches to Pattern Recognition
      The page discusses different theories of object recognition: template matching, prototype matching, and feature analysis. Template matching involves comparing objects to stored templates, but it struggles with recognizing objects from different perspectives. Prototype matching uses an average of patterns for recognition, allowing for some variance in perception. Feature analysis focuses on identifying critical features of objects.
    • 12.2: Face Recognition Systems
      Prosopagnosia, or face blindness, is a cognitive disorder that impairs the ability to recognize faces. It can be either acquired or developmental, with the latter potentially affecting up to 4% of children and 2.5% of adults. The disorder is not associated with neurological damage or socio-emotional issues. Diagnosis often involves tests like the Cambridge Face Memory Test.
    • 12.3: Concepts and Categories
      The text examines the concept of categories and concepts, highlighting how individuals learn, categorize, and apply this understanding in daily life. It discusses how categories, although diverse, share commonalities making them informative. Concepts, which are mental representations of categories, guide behavior and learning. The text also explores the complexities of category definition, revealing issues like fuzzy boundaries and typicality.
