Effects of the perceived diagnosticity of presented attribute and brand name information on sensitivity to missing information

摘要

Four experiments demonstrated that as the perceived diagnosticity of the presented information increases, sensitivity to missing diagnostic information decreases. However, experts were sensitive to missing information regardless of the diagnosticity of the presented attribute information. When a well-known brand name was paired with the attribute information, novices were insensitive to missing information regardless of the diagnosticity of the presented attribute information. Implications of the results for understanding information utilization and omission neglect are discussed.
