Social psychology can contribute to a study of tourist- guide interaction through its emphasis on the dynamics, behavior and cognitions of social situations. A conceptual contribution to the study of tourist- guide encounters can structure inquiry on the topic, thereby correcting the piecemeal nature of current research. The conceptual overview adopted follows that of Argyle et al. (1981) and emphasizes eight features of social situations: goals, rules, roles, element, sequences, cognitive structures, environmental setting, and language. A diagrammatic synthesis of this material is outlined. In reviewing previous research the generative question-asking power of this overview is demonstrated. Two of the situation features proposed are discussed at greater length for six tourist- guide interactions.
