The aim of this paper is to provide perceptual scientists with a quantitative framework for modeling a variety of common perceptual behaviors, and to unify various perceptual inference tasks by exposing their common computational underpinnings. This paper derives a model Bayesian observer for perceptual contexts with linear Gaussian generative processes. I demonstrate the relationship between f...

Two commonly accepted functions of the mammalian hippocampus are the processing of spatial information and behavioral inhibition. Although there is clear evidence that the avian hippocampus is also critical for the processing of spatial information, there is a dearth of evidence that it plays a role in behavioral inhibition. In Experiment 1, the effect of hippocampal lesions on behavioral inhib...

Persistent genital arousal disorder is a newly recognized condition that is poorly understood. There is a paucity of research in this area and there are concerns as to the validity of the results of what little research there has been. This article aims to draw together current literature on this topic and provide readers with guidance on the management of this condition. This includes a workin...

Two experiments compared 7- and 8-year-olds' and 9- and 10-year-olds' ability to use semantic analysis and inference from context to understand idioms. We used a multiple-choice task and manipulated whether the idioms were transparent or opaque, familiar or novel, and presented with or without a supportive story context. Performance was compared with that of adults (Experiment 1) and 11- and 12...

This article discusses a perception experiment to investigate the relation between auditory and visual cues for marking prosodic prominence. The methodology makes use of a reaction-time experiment. For this experiment, recordings of a sentence with 3 accents were systematically manipulated in such a way that auditory and visual markers of prominence were either congruent (occurring on the same ...

American Journal of Speech-Language Pathology • Vol. 5 • 1058-0360/96/0503-0007 © American Speech-Language-Hearing Association The ear is the essential tool of the speech-language pathologist. Auditory-perceptual judgments are typically the final arbiter in clinical decisionmaking and often provide the standards against which instrumental (so-called “objective”) measures are evaluated. Although...

In this study, the authors explore a newly constructed dynamic assessment (DA) intended to tap inference-making skills that they hypothesize will be predictive of future comprehension performance. The authors administered the test to 100 second-grade children using a dynamic format to consider the concurrent validity of the measure. The dynamic portion of the assessment comprised teaching child...

The effects of sensory signal characteristics on the duration discrimination of intermodal intervals was investigated in three experiments. Temporal intervals were marked by either the successive presentation of a visual then auditory signal (VA), or by the successive presentation of an auditory then visual signal (AV). The results indicated that (1) VA intervals are generally easier to discrim...
