Differential fan effect and attentional focus

As people study more facts about a concept, it takes longer to retrieve a particular fact about that concept. This fan effect (Anderson, 1974) has been attributed to competition among associations to a concept. Alternatively, the mental-model theory (Radvansky & Zacks, 1991) suggests that the fan effect disappears when the related concepts are organized into a single mental model. In the present study, attentional focus was manipulated to affect the mental model to be constructed. One group of participants focused on the person dimension of personlocation pairs, whereas the other group focused on the location dimension. The result showed that the fan effect with the focused dimension was greater than the fan effect with the nonfocused dimension, which is contrary to the mental-model theory. The number of associations with a concept is indeed crucial during retrieval, and the importance of the information seems to be accentuated with attentional focus.     

Predicting consumer satisfaction from CD players

This paper explores the relationship between expectations and product satisfaction evaluations in a high‐involvement product category. While doing so, the paper attempts to develop a regression model to predict the overall level of consumer satisfaction derived from CD players, using a number of explanatory variables within an ordinary least squares framework. This regression model links overall satisfaction to confidence in other people's opinions, expectations of product quality, experience with product quality, replacement rate and the importance of price. The model predicts fairly well for cross‐sectional data, with an adjusted R² of 57 per cent, and appears to be robust. Finally, the implications of these results for marketers are discussed.

Comments on Richard Jeffrey

In this commentary, after first summarizing the three major theses of Jeffrey's paper ‘Probability and Falsification: Critique of the Popper Program’, and sketching out what I take to be his central argument, I criticize Jeffrey on two grounds. The first is that he has failed to explain why his version of Bayesianism provides us with better theories upon which to make decisions; the second is that he has offered a theory about decision-making that by-passes the important question: How can we make more rational decisions?     

Distinct Activity Patterns of the Human Bed Nucleus of the Stria Terminalis and Amygdala during Fear Learning

Neuropsychology Review - The amygdala and, more recently, also the bed nucleus of the stria terminalis, have been widely implicated in fear and anxiety. Much of our current knowledge is derived...     

Contrasting rule-based and similarity-based category learning: The effects of mood and prior knowledge on ambiguous categorization

This study adopts a dual-system view of category learning. The findings suggest that consumers who learn a dominant feature as a verbal rule for a product category will classify a new ambiguous product according to that feature even if it more closely resembles a different product category. The findings also demonstrate that dominant features can bias categorization toward a less prototypical category in the event that the new product breaks the rule. We refer to this phenomenon as criterial inferencing. Lastly, we offer unique empirical evidence to suggest that mood influences category learning and thus attenuates the criterial inferencing bias.     

On understanding without words: Communication between a deaf-blind child and her parents

This paper is an empirical inquiry into the nature of human communication and understanding. It is organized into three sections. First, there is an overview of the ethnomethodological critique of mainstream social scientific research methodology and the relevance of this critique to clinical behavioral research. Second, the details of an ethnomethodological study of communication practices in a family with an alingual, deaf-blind child are provided. Third, implications of the case study are presented.The author's participation in this research was supported by PSH grant HD04612 NICHD and HD-05540-02, Patterns of Care and the Development of the Retarded, Mental Retardation Study Center, U.C.L.A. Medical Center. I wish to acknowledge the efforts of various persons during different phases of this writing. The general perspective taken in this article was based upon a course of study with Harold Garfinkel and Melvin Pollner. They, Robert Emerson, Warren TenHouten, and Michael McGuire, reviewed a chapter of my dissertation containing this data. Robert Edgerton, Sylvia Bercovici and Donald Sutherland of U.C.L.A.'s Mental Retardation Study Center also helped with suggestions about initial drafts.
