This paper, discussing use of electrical stimulation by postlingually deafened adults to supplement speechreading, focuses on: information conveyed by vision, acoustic information needed to resolve visual confusions, basic psychophysical abilities of cochlear implant patients, auditory-alone and audiovisual perception by cochlear-implant patients,…

Research is reviewed on auditory-visual speech perception of hearing-impaired individuals. The review focuses on: the effects of competing noise, filtering, age, stimulus and noise, and hearing loss on perceptual behavior; bisensory communication evaluation procedures; and remediation of bisensory perceptual problems through consonant recognition…

Used a new statistical procedure to examine consensual beliefs about situations common to universities. This approach aims at constructing a joint hierarchical or non-hierarchical classification of situational categories. Results indicate that a psychologically meaningful and methodologically satisfactory representation of the cognitive…

This study of visual and auditory problems in 17 children (ages 7-10) with dyslexia concluded that, although eye tracking and binocular fusion problems should always be considered in the assessment of dyslexics, factors involved in information processing in auditory and visual perception appear to be more highly implicated.

In 2 experiments, the authors tested whether the classical modality effect--that is, the stronger recency effect for auditory items relative to visual items--can be extended to the spatial domain. An order reconstruction task was undertaken with four types of material: visual-spatial, auditory-spatial, visual-verbal, and auditory-verbal.…

This study examines the extent sex and ethnicity play in perceptions that university students have of teacher credibility. Students were sampled at a university with a predominately Hispanic population. A multivariate effect was found for teacher ethnicity on perceptions of competence and caring, with Caucasian instructors rated higher than…

The Wernicke-Lichtheim-Geschwind (WLG) theory of the neurobiological basis of language is of great historical importance, and it continues to exert a substantial influence on most contemporary theories of language in spite of its widely recognized limitations. Here, we suggest that neurobiologically grounded computational models based on the WLG…

As think tanks have become more numerous, visible, and seemingly influential, scholars have begun to pay more attention to them--analyzing their characteristics, their modes of operation, and their roles in policymaking. This "Policy Insight" builds on this work and examines the role of think tanks in civil society, with an emphasis on…

The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5-7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in…

The study of infant communication during mother-infant interactions has largely focused on infants' distal behaviours, while neglecting their more proximal behaviours, such as touch. Yet, touch is an important modality through which infants and mothers communicate; it is also a vital means through which infants self-regulate and explore their…

The Ebbinghaus (Titchener) illusion was examined in a remote culture (Himba) with no words for geometric shapes. The illusion was experienced less strongly by Himba compared with English participants, leading to more accurate size contrast judgments in the Himba. The study included two conditions of inducing stimuli. The illusion was weaker when…

Purpose: The purposes were (a) to compare masking of consonant bursts by adjacent vowels for listeners with and without hearing loss and (b) to determine the extent to which the temporal intraspeech masking can be reduced by a simulated hearing-aid frequency-response shaping. Method: Fourteen adults with sensorineural hearing loss and 10 with…

Do the viewpoint costs incurred when naming rotated familiar objects arise during initial identification or during consolidation? To answer this question we employed an attentional blink (AB) task where two target objects appeared amongst a rapid stream of distractor objects. Our assumption was that while both targets and distractors undergo…

It has been proposed that visual recognition memory and certain attentional mechanisms are impaired early in Alzheimer disease (AD). Little is known about visuospatial recognition memory in AD. The crucial role of the hippocampus on spatial memory and its damage in AD suggest that visuospatial recognition memory may also be impaired early. The aim…

Two experiments with the inductive generalization procedure tested whether 16- and 20-month-old infants understand that animals and not vehicles follow a rational path to reach a goal. Infants were tested with four different events and the model exemplar was either an animal or ambiguous block. Results showed that infants at 20 months of age, but…
