Fritz Heider's paper explores the principles of organizational processes in the perceptual field and their application to social perception. Heider argues that one of the key features of social perception is the attribution of changes to a perceptual unit, such as attributing movement to an object or an individual. This attribution is influenced by causal reasoning, where the origin and change are perceived as causally dependent. Heider discusses the role of causal attribution in social perception, including the tendency to attribute changes to personal origins and the influence of these attributions on social behavior. Heider examines the concept of "phenomenal causality," where the origin and change are perceived as causally linked, and the role of causal integration in shaping the perception of social behavior. He also explores the dynamics of causal units, where the act and the person are perceived as parts of a causal unit, and how these units influence each other. Heider highlights the importance of similarity and proximity in causal attribution, as well as the influence of past experiences and environmental factors on these perceptions. The paper further discusses the impact of causal attribution on emotional states and attitudes, showing how attributions can affect feelings of success or failure, aggression, and self-esteem. Heider also examines the influence of needs and attitudes on attribution, suggesting that these factors can lead to cognitive restructuring and the formation of causal units that align with personal goals and values. Overall, Heider's work provides a comprehensive analysis of how causal attribution influences social perception and behavior, emphasizing the role of personal origins and the dynamic interplay between the origin and the effect in shaping our perceptions and reactions.Fritz Heider's paper explores the principles of organizational processes in the perceptual field and their application to social perception.
