A cognitive approach to the representation of managerial competitive intelligence knowledge.

Johnson, Richard James. January 1994 (has links)
With today's rapidly changing business environment, more and more businesses are using competitive intelligence to improve planning efforts, identify threats and opportunities and help avoid unpleasant surprises. However, to be effective, this intelligence must be gathered and communicated between managers. Two research questions will address these issues: (1) can a representation of competitive knowledge be developed that reflects managerial thought and (2) will a graphical computer tool based on this representation elicit a more complete representation of competitive intelligence knowledge in a more efficient manner relative to traditional methods? Various studies have shown managerial thought to be represented in several ways, e.g., conceptual groupings, hierarchically, and causally. However, by proposing that managers represent information about competitors in a story structure and integrating this proposal with the literature from competitive intelligence and strategic planning, a more complete conceptual model results. To validate the proposed conceptual model, an archival case study of three competitors in the computer workstation market was conducted. Following that, interviews were conducted with six MBA students with experience in competitive intelligence and with six managers. The transcripts from these interviews have been analyzed and the conceptual model has been modified based on input from this content analysis. A prototype was developed using the ConceptBase platform, an X-windows tool that provides both graphical and textual access to concepts and their relationships. The prototype will allow managers to create a graphical representation of their competitive knowledge. This representation will allow managers to locate gaps in their knowledge and to communicate their information to others. The prototype was validated by two different groups of MBA students by asking them to represent a given competitive situation. One group used pencil and paper while the second group used the prototype. Both the number of uncategorized concepts and the number of relationships differed significantly. This indicates that a more complete representation was created using the prototype. The two main contributions of this research are: (1) a model of competitive intelligence knowledge based on managerial cognition, and (2) a prototype that will facilitate the elicitation of competitive intelligence knowledge in a graphical and understandable manner.

Fuzzy trace theory and the development of interference in recognition and recall.

Kneer, Ryan Taylor. January 1994 (has links)
This study addressed the free recall and recognition memory processes of elementary school children. It has been discovered that when children recall items from episodically related collections, a non-monotonic relationship is found between the memory strengths of those items and the order in which they are recalled. This relationship is known as cognitive triage, and it is not understood if the same phenomena would occur with recall involving semantic memory. Regarding recognition memory, experiments have tapped children's tendency to falsely remember words whose gist is the same as the gist of newly learned items. These past studies have focused primarily on a reversal of the standard false-recognition effect, where related distractors were easier to reject than unrelated distractors under some conditions. No research to date has ignored reversals and clearly examined the false-recognition effect itself. This study examined kindergarten, third, and sixth grade children's free recall organization and false-recognition of related distractors. The cognitive triage experiment examined semantic memory through having children recall exemplars from categories in Battig and Montague's (1969) lists. The recognition experiment examined developmentally the differential rate of false-recognition for related and unrelated distractors. Fuzzy Trace Theory (FTT) contends that the ability to inhibit interference increases with age. Hence, younger children were hypothesized to show a weaker cognitive triage effect and more false-recognition than older children. The latter result was found, whereas the former result was not. False-recognition did decrease with age but although a triage effect was observed for category exemplar production, the effect did not vary developmentally. The principle difference between this triage study and previous research is that lists offering preexperimental measures of memory strength were employed. These lists were normed on adults and therefore cognitive triage may have been different for children. Thus, this study indicates that developmental effects are found for false-recognition of related distractors but not for category exemplar production when using Battig and Montague's (1969) lists.
