The document discusses Harry Stack Sullivan's interpersonal theory and the three levels of cognition: prototaxic, parataxic, and syntactic. Prototaxic experiences are preverbal and impossible to communicate. Parataxic experiences are personal and prelogical and can only be communicated in a distorted form. Syntactic cognition involves meaningful interpersonal communication through logical thinking and shared language. The document provides examples of each level of cognition.
