Intentionality and interpersonal relations.

The present commentary re-introduces Heider's (1958) common-sense psychology and his treatment of intentionality, comparing and contrasting his theoretical formulations with those of Elstrup (IPBS: Integrative Psychological & Behavioral Science 43:4, 2009). Special emphasis is made in all those aspects of Heider's theory that are related to the perception, interpretation, prediction and control of our behavior and that of another person. Also, different social aspects of interpersonal relations are presented. Finally, some ideas regarding different approaches to the study of attributing are discussed.
