The Role of Abstract and Specific Knowledge in the Formation of Product Judgments: An Analogical Learning Perspective

Prior research has assumed that existing knowledge exerts its influence on consumer judgments primarily through abstract knowledge structures. Consequently, little attention has been given to the possibility that judgments may, under certain circumstances, be influenced by knowledge associated with more specific knowledge structures. This article examines the factors responsible for determining the impact of abstract versus specific knowledge on consumer judgments. Based on the Consumer Learning by Analogy model (CLA model; Gregan‐Paxton & John, 1997), it is argued that the relative influence of abstract and specific knowledge is a function of (a) the relation between the new product and existing knowledge and (b) the nature of consumer's knowledge. These ideas were tested in a series of experiments in which participants were required to judge a new product that varied in its relation to an existing product or brand. In this context, the influence of specific knowledge was most evident when participants were able to construct an attribute mapping, but not a relational mapping, to link the novel product to a familiar brand exemplar. When it was possible to construct a relational mapping, a more abstract knowledge structure, such as a schema, was retrieved and used as the basis of product judgments.     

Manual dexterity in the gorilla: bimanual and digit role differentiation in a natural task

The manipulative actions of mountain gorillas Gorilla g. beringei were examined in the context of foraging on hard-to-process plant foods in the field, in particular those used in tackling thistle Carduus nyassanus. A repertoire of 72 functionally distinct manipulative actions was recorded. Many of these actions were used in several variants of grip, finger(s) and movement path, both by different individuals and by the same individual at different times. The repertoire appears somewhat greater than that observed in comparable studies of monkeys, but a far more striking difference is found in the use of differentiated actions in concert. Mountain gorillas routinely and frequently deal with problems that involve: (1) bimanual role differentiation, with the two hands taking different roles but synchronized in time and space, and (2) digit role differentiation, with independent control of parts of the same hand used for separate purposes at the same time. The independent control that allows these abilities, so crucial to human manual constructional ability, is apparently general in African great apes. Role differentiation, between and within the hand, is evidently a primitive characteristic in the human arsenal of skills. Accepted after revision: 6 April 2001 Electronic Publication     

Salesperson characteristics affecting consumer complaint responses

The important relationship between consumer complaint behaviour and brand and store loyalty is well established. The range of factors that favourably influence the outcomes of complaining have received relatively less research attention. Therefore, this study tests the effects of two salesperson source characteristics: willingness to listen and product/store knowledge, on consumer complaint‐related perceptions and intentions in a retail setting. Mall shoppers participated in a consumer complaint experiment to test the hypothesised effects. The results indicate that both characteristics affect customer complaint responses, as well as consumer perceptions of the salesperson and the retail store. The findings of the study demonstrate that salesperson characteristics are important influences on positive or negative consumer complaint responses.

THE EFFECTS OF FORM TRAINING ON FOUL‐SHOOTING PERFORMANCE IN MEMBERS OF A WOMEN'S COLLEGE BASKETBALL TEAM

The effects of instruction and feedback in proper form on foul‐shooting performance was evaluated in 3 players of a women's NCAA Division II college basketball team. Players showed an increase in percentage of shots made and in correct form compared to baseline shooting without instruction or feedback. All players reached criterion within seven training sessions. The results suggest that training proper form is an effective strategy for improving foul‐shooting performance.     

Evidence of Impaired Glucose Tolerance and Insulin Resistance in Patients With Alzheimer’s Disease

Alzheimer’s disease (AD) and diabetes rarely occur together, a finding that provides a possible clue as to the development of AD. Abnormal glucose metabolism is not limited to diabetes, but also can include impaired glucose tolerance, insulin resistance, and hyperinsulinemia. AD patients have significantly varying insulin levels after drinking sugared sodas and thus may be classified as insulin resistant. After reviewing the literature on impaired glucose tolerance and insulin production in AD, we present several hypotheses as possible explanations for the relationship between insulin resistance and AD. Finally, we suggest future studies, including studies on use of thiazolidinediones (currently used in the treatment of diabetes) in AD.     

Interviewing Witnesses: Forced Confabulation and Confirmatory Feedback Increase False Memories

In two experiments, adults who witnessed a videotaped event subsequently engaged in face-to-face interviews during which they were forced to confabulate information about the events they had seen. The interviewer selectively reinforced some of the participants' confabulated responses by providing confirmatory feedback (e.g., "Yes, _is the correct answer") and provided neutral (uninformative) feedback for the remaining confabulated responses (e.g., "O.K. _"). One week later, participants developed false memories for the events they had earlier confabulated knowingly. However, confirmatory feedback increased false memory for forcibly confabulated events, increased confidence in those false memories, and increased the likelihood that participants would freely report the confabulated events 1 to 2 months later. The results illustrate the powerful role of social-motivational factors in promoting the development of false memories.     

HAUERWAS AMONG THE VIRTUES

Despite the fact that Stanley Hauerwas has not taken up many of the topics normally associated with virtue ethics, has explicitly distanced himself from the enterprise known as “virtue ethics,” and throughout his career has preferred other categories of analysis, ranging from character and agency to practices and liturgy, it is nevertheless clear that his work has had a deep and transformative impact on the recovery of virtue within Christian ethics, and that this impact has largely to do with the ways in which his thought resists normalization. This essay traces the evolution of Hauerwas's reflections on virtue and the virtues over the course of his career, with special attention to how this has been bound up with an increasingly emphatic theological particularism that has remained ambivalent between what I term “comprehensive” versus “exclusive” particularism. I argue that it is important to distinguish between these, and suggest that grasping the destructive tendencies of “exclusive” particularism should cement our commitment to shouldering the responsibilities associated with comprehensive particularism.     

Identifying Changes in Youth's Subgroup Membership Over Time Based on Their Targeted Communication About Substance Use with Parents and Friends

Using latent class/transition analyses, this study: (a) identified subgroups of youth based on their targeted communication about substance use with parents and friends, (b) examined subgroup differences in substance use, and (c) considered changes in subgroup membership over four years. Among 5,874 youth, five subgroups emerged, with parents‐only communicators having the lowest substance use. Friends‐only and consequence‐focused communicators reported the overall highest use. Subgroup membership was mostly stable across the four years. If, however, youth transitioned, those who began as parents‐only, consequence‐focused, or friends‐only communicators during the first year were most likely to transition to comprehensive communicators by the last year. Youth who started as noncommunicators or comprehensive communicators were most likely to end up as parents‐only communicators.     

The Delay Hypothesis: The Manifestation of Media Effects Over Time

A between‐participants experiment (N = 147) tested for the presence of a delayed effect following exposure to an episode of a legal drama that contained false information. Participants were more likely to endorse false beliefs if they were queried two weeks after watching the program rather than immediately following exposure. The relationship between time and false belief endorsement was found to be moderated by perceived reality of the program. Consistent with the delay hypothesis, those who perceived the legal drama to be unrealistic following exposure had significantly higher false belief scores at Time 2.
