Using Visual Media Technologies To Investigate Cognitive Representation of Technical Diagrams.
This paper describes how visual media technologies have been used to support research into the way technical diagrams are represented in people's minds. Two groups of subjects participated in this research, individuals with either a high or a low level of expertise in meteorology, specifically professional meteorologists and non-meteorologists. Two general types of visual media technologies--computers and video--were used to investigate the mental representation of diagrams. Two main types of data were collected by the computer and video methodologies: (1) process data, the actions subjects perform as they work through a task; and (2) product data, the outcomes (drawings) of copying, recalling, or completing a weather map. Examples of the way process and product data were handled during analysis are presented. The strength of video technology is that it provides for the capture of highly detailed visual data. However, it also presents problems with the time-consuming nature of transcribing the data into a form suitable for statistical analysis. In contrast, computer technology can directly monitor some aspects of a subject's performance and save the generated data in files that are suitable for statistical analysis, although it is not currently capable of directly providing (for reasonable cost and effort) the type of facilities for dealing with visual data that are available with video. Recent merging of the two technologies with the advent of digital video is opening up new possibilities for research. (Contains 15 references.) (AEF)
