Similarity plays a critical role in many judgments and choices. Traditional models of similarity posit that increasing the number of differences between objects cannot increase judged similarity between them. In contrast to these previous models, the present research shows that introducing a small difference in an attribute that previously was identical across objects can increase perceived similarity between those objects. We propose an explanation based on the idea that small differences draw… 
The Difference of User Perception between Similarity and Dissimilarity Judgments
The main purpose of this paper is to study the user perception by using similarity judgments and MDS analysis was used to explore the difference of user perception between similarity and dissimilarity judgments.
The processing of perceptual similarity with different features or spatial relations as revealed by P2/P300 amplitude.

Users in the loop: a psychologically-informed approach to similar item retrieval
A framework for evaluating users' judgments of similarity that is informed by best practices in psychological research methods is developed, and it is demonstrated that a psychologically-informed similarity function (i.e., Tversky contrast model) outperforms an psychologically-naive similarity function in predicting users' similarity judgments.
Salience and Consumer Choice
We present a theory of context-dependent choice in which a consumer’s attention is drawn to salient attributes of goods, such as quality or price. An attribute is salient for a good when it stands
Unraveling the Information Role of Online Reviews: Distinguishing between the Competing Effect, Local and Global Peer Effects on Consumer Choice
The valence, volume and dispersion of valences of reviews posted by local peers are found to have influences on purchase decisions, and local peer effects exert more significant influences on consumer choices as compared to global peer effects.
Naloxone modulates visual judgments of similarity but not dissimilarity
It is suggested that naloxone decreased the “similarity criterion” in comparative judgments, indicating its potentially modulatory effect on visual cognition.
Information overload, choice deferral, and moderating role of need for cognition: Empirical evidence
Choice deferral due to information overload is an undesirable result of competitive environments. The neoclassical maximization models predict that choice avoidance will not increase as more
Recommendation Agent Acceptance: The Impact of Decision Difficulty in RA Sets of Multidimensional Products
Recommendation Agents aim at reducing decision effort and improving quality through recommending a set of alternatives which fits users’ preferences. The list of the alternatives is typically
Selling to Consumers with Intransitive Indi ff erence *
We are indifferent between two cups of coffee when one differs from the other in having only one more grain of sugar. But such an indifference is not transitive, because eventually, after many enough
Too Much Choice: End-User Privacy Decisions in the Context of Choice Proliferation
It is found that participants who are confronted with a larger amount of privacy options subsequently report more negative feelings, experience more regret, and are less satisfied with the choices made if the number of options remains constant.


Similarity Involving Attributes and Relations: Judgments of Similarity and Difference Are Not Inverses
Conventional wisdom and previous research suggest that similarity judgments and difference judgments are inverses of one another. An exception to this rule arises when both relational similarity and
Respects for similarity
This article reviews the status of similarity as an explanatory construct with a focus on similarity judgments. For similarity to be a useful construct, one must be able to specify the ways or
Features of Similarity
The metric and dimensional assumptions that underlie the geometric representation of similarity are questioned on both theoretical and empirical grounds and a set of qualitative assumptions are shown to imply the contrast model, which expresses the similarity between objects as a linear combination of the measures of their common and distinctive features.
Processes of Similarity Judgment
An experiment is presented that differentiates among extant structural accounts of similarity in their ability to account for patterns of similarity ratings, a challenge for transformation-based models and all but one mapping-based model, the Similarity as Interactive Activation and Mapping model of similarity.
Splitting the Differences: A Structural Alignment View of Similarity
The similarity of a pair increases with its commonalities and decreases with its differences (Tversky, 1977, Psychological Review, 79(4), 281-299). This research addresses how the commonalities and
Consumer Preference for a No-Choice Option
The traditional focus in the decision-making literature has been on understanding how consumers choose among a given set of alternatives. The notion that preference uncertainty may lead to choice
The Effect of Common and Unique Features in Consumer Choice
Consumer choice often involves a comparison among the available alternatives. Recent research finds that features shared by alternatives are canceled and greater weight is placed on the unique
When choice is demotivating: can one desire too much of a good thing?
Experimental studies show that people are more likely to purchase gourmet jams or chocolates or to undertake optional class essay assignments when offered a limited array of 6 choices rather than a more extensive array of 24 or 30 choices.
The cost of richness: the effect of the size and diversity of decision sets on post-decision regret.
The larger number of alternatives from which one can choose and the more diverse those alternatives are, the stronger the regret that an unsatisfactory choice would cause, according to 2 hypotheses.
The Effect of Forced Choice on Choice
Whereas most academic and industry studies of consumer preferences and decision making involve forced choice (i.e., participants are told to choose one of the presented product or service
