Three of the stages in this model-selective attention/comprehension, encoding and simplification, and storage and retention-describe how specific social information is observed and stored in memory. The fourth and final stage, retrieval and response, involves turning mental representations into real-world judgments and decisions. The information processing model in Figure 7-1 helps us understand how we take in, process, and use information. Using each of the stages of the model, identify specific manager actions that can improve decisions
