The relationship between expertise and evaluative extremity: the moderating role of experts' task characteristics.

Past research has yielded contradictory results with regard to the relationship between expertise and evaluative extremity. The authors suggest that this apparent contradiction is due to the task characteristics of the expert activity. The primary task of certain experts is to formulate overall (configural) judgments and to generate clear, unambiguous answers. These experts tend to give relatively extreme evaluations. Other experts generally communicate the implications of the different choice alternatives and explain featural aspects of the stimuli. These experts are characterized by relatively moderate evaluations. The research reported in this article shows that experts whose expert activity involves configural judgments tend to make more extreme evaluations than experts who generally provide others with featural explanations. It also demonstrates that experts' task characteristics affect the way they store stimulus-relevant attributes in memory.

Feeling-of-knowing for proper names.

The main objective of the presented study was to study feeling-of-knowing (FOK) in proper name retrieval. Many studies show that FOK can predict performance on a subsequent criterion test. Although feeling-of-knowing studies involve questions about proper names, none make this distinction between proper names and common names. Nevertheless, the specific character of proper names as a unique label referring to a person should allow participants to target precisely the desired verbal label. Our idea here was that the unique character of proper name information should result in more accurate FOK evaluations. In the experiment, participants evaluated feeling-of-knowing for proper and common name descriptions. The study demonstrates that FOK judgments are more accurate for proper names than for common names. The implications of the findings for proper names are briefly discussed in terms of feeling-of-knowing hypotheses.

Fictitious Academic Expertise and Processing Resources.

A previous study showed that pairs of students interacting in a second language produced more words when they were assigned a fictitious expert position in a specific competence dimension than when they were assigned a nonexpert position. It has also been shown that the usual level of expertise has an impact on the assigned fictitious expertise effect. The present study was designed to determine whether the processing capacity allotted to the current task could partly determine performance. A given position of expertise may demand a large or small attentional capacity. Two experiments were conducted using a dual-task paradigm. As expected, the different expertise positions led to different reaction times on the secondary task. The second experiment showed that the impact of assigning a position of expertise to students depends on their usual academic standing. This study supports the idea that in interactive situations, performance variations as a function of the expertise position can be partially explained by differences in the processing resources allocated to the task. Implications for teaching are discussed. Copyright 2001 Academic Press.
