We propose that similarity is determined by the transformation distance between representations: entities which are perceived to be similar have representations which are readily transformed into one another, whereas transforming between dissimilar entities requires many transformations. We present three experiments that indicate that similarity is strongly influenced by transformation distance. These data present a challenge for featural or spatial accounts of similarity. Finally, we introduce…

Determining transformation distance in similarity: Considerations for assessing representational changes a priori
TLDR
The difficulties inherent in determining what transformations are psychologically salient and the importance of considering the directionality of transformations are demonstrated.
Similarity as tractable transformation
According to the transformational approach to similarity, two objects are judged to be more similar the simpler the transformation of one of the object representations into the other. This approach
Transformations and asymmetry
The transformational approach to similarity views similarity as a function of the complexity of the transformations required to ‘distort’ the representation of one object into another. These
Transformation and representation in similarity
Similarity, being a psychological notion, involves the comparison of finite object representations. The specific nature and complexity of these representations is a matter of fierce theoretical
Transformation and alignment in similarity
TLDR
It is argued that perceptual theory suggests that transformations and alignment processes should generally be viewed as complementary, in contrast to the current distinction in the literature.
When do learned transformations influence similarity and categorization?
TLDR
Overall, this work suggests that newly learned transformations can impact similarity judgments but the salience of the transformation has a large impact on transfer.
Transformation Direction Influences Shape-Similarity Judgments
TLDR
Across three experiments, similarity ratings for identical comparisons were higher when the reference object, B, had appeared before the comparison object, A, in the preceding morph sequence.
Transformation Direction Influences Shape-Similarity
Three experiments provide evidence that the perceived similarity between two images is systematically affected by the inherent direction of a transformation that links the two. Participants were
Applications of classification based on similarities and dissimilarities
In this paper, we first review some definitions and propositions regarding similarities between two objects (2-similarity), or among three or more objects (3-similarity/n-similarity). Then the notion
Processes of Similarity Judgment
TLDR
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.

TLDR
It is concluded that the transformational structure between the given pair of configurations should be the very important and effective determinant for their similarity and suggested that similarity cognition is a dynamic cognitive process involving cognitive transformations of given configurations.

Relational similarity and the nonindependence of features in similarity judgments
TLDR
The MAX hypothesis is introduced, in which attributional and relational similarities are separately pooled, and shared features affect similarity more if the pool they are in is already relatively large.

TLDR
A reassessment of evidence indicates that similarity can be sufficiently constrained and sophisticated to provide at least a partial account of many categories.

Hitherto, theories of similarity have restricted themselves to judgments of what might be called literal similarity. A central thesis of this article is that a complete account of similarity needs

TLDR
This paper identifies a number of possibly desirable properties of a shape similarity method, and determines the extent to which these properties can be captured by approaches that compare local properties of the contours of the shapes, through elastic matching.
Mechanisms of Analogical Learning.
TLDR
This paper decomposes similarity-based transfer into separate subprocesses and compares how different kinds of similarity affect each of these processes.
