摘要：This paper describes a newly developed online perceptual testing and training tool called the Perceptual Chronograph. This tool was initially developed to test the reaction of salespeople to customer verbal and nonverbal cues in an experimentally designed ‘sales transaction’. The Chronograph records the correct or incorrect identification of target or manipulated information, (signal detection theory), records the sensor’s evaluation of the information, and also records reactions that a sensor would have in response to the identified information. The Chronograph has virtually unlimited potential for media richness: verbal, nonverbal, visual, contextual or even temporal information can be included. It also has the potential to be used as a training device, whereby exemplary sensors are tested and their response patterns analyzed to create a ‘fuzzy gold’ standard of behavior. Novice or less perceptually astute sensors (the ‘novice’) can be tested and their results analyzed. The differences between the exemplar and the novice can then be compared, either at the time of testing, or in a later training session. After feedback is given, the novice can be re-tested to ensure learning. Although the Chronograph was developed and tested in the sales context, it has learning and testing applications in many areas of research where a sensor (person or system) must perceive, evaluate, and respond to uncertain or conflicting information: (e.g., social perception, forecasting, and medical diagnosis).
