In two experiments, the perceptual similarity between a strong tonal melody and various transpositions was investigated using a paradigm in which listeners compared the perceptual similarity of a melody and its transposition with that of the same melody and another transposition. The paradigm has the advantage that it provides a direct judgment regarding the similarity of transposed melodies. T...

This paper reports a series of analyses of consonant identification data from Cutler, Weber, Smits, & Cooper (2004) and which empirically derive perceptual similarity to determine how it compares with feature-based models of phoneme similarity. A model in which minimal contrast structure is equivalent to perceptual structure provides a baseline 'null hypothesis'. This baseline model is compared...

Perceptual similarity between stimuli is often assessed via generalization, the response to stimuli that are similar to the one which was previously conditioned. Although conditioning procedures are variable, studies on how this variation may affect perceptual similarity remain scarce. Here, we use a combination of behavioural and computational analyses to investigate the influence of olfactory...

Foreign accent has been assumed to be closely related to the degree of articulatory, acoustic and perceptual similarity between L1 and L2 sounds. This study examined cross-language acoustic and perceptual similarities between Korean and English sibilant fricatives: Korean [−tense] /s/ and [+tense] /s*/ vs. English alveolar /s/ and palato-alveolar /ʃ/. To determine acoustic similarity, two param...

In this paper, we demonstrate how texture classification and retrieval could benefit from learning perceptual pairwise distance of different texture classes. Textures as represented by certain image features may not be correctly compared in a way that is consistent with human perception. Learning similarity helps to alleviate this perceptual inconsistency. For textures, psychological experiment...

Visual search for a target among distractors is often speeded when the target-defining feature is repeated from trial to trial, compared to when it changes. It has been proposed that whether this intertrial priming effect is perceptual in nature or not, and how strong it is, depends on the perceptual ambiguity of the display. Using the event-related potential (ERP) method, Experiment 1 assessed...

The process of comparison is fundamental to behaving organisms. Generalization from past to present experience involves a measure of the similarity of present perceptual input to what has been perceived before. The likelihood that we call some object a dog is a function of the perceptual similarity of that candidate object to other objects known to be dogs. But humans do far more than simply ca...

Does perceptual grouping operate early or late in visual processing? One position is that the elements in perceptual layouts are grouped early in vision, by properties of the retinal image, before perceptual constancies have been determined. A second position is that perceptual grouping operates on a postconstancy representation, one that is available only after stereoscopic depth perception, l...
