Deficits in temporal resolution and/or the precedence effect may underlie part of the speech understanding difficulties experienced by older listeners in degraded acoustic environments. In a previous investigation, R. Roberts and J. Lister (2004) identified a positive correlation between measures of temporal resolution and the precedence effect,…

The murine vibrissae sensorimotor system has been scrutinized as a target of motor learning through trace classical conditioning. Conditioned eyelid responses were acquired by using weak electrical whisker-pad stimulation as conditioned stimulus (CS) and strong electrical periorbital stimulation as unconditioned stimulus (US). In addition,…

Negative priming refers to slowed down reactions when the distractor on one trial becomes the target on the next. Following two popular accounts, the effect might be due either to inhibitory processes associated with the frontal cortex, or to an ambiguity in the retrieval of episodic information. We used event-related brain potentials (ERPs) to…

Many children with autism display reactions to auditory stimuli that seem as if the stimuli were painful or otherwise extremely aversive. This article describes, within the contexts of three experimental designs, how procedures of systematic desensitization can be used to treat hypersensitivity to auditory stimuli in three young children with…

Evoked potential studies have demonstrated that musicians have the ability to distinguish musical sounds preattentively and automatically at the temporal, spectral, and spatial levels in more detail. It is however not known whether there is a difference in the early processes of auditory data processing of musicians. The most emphasized and…

A number of interaction researchers have claimed that recasts might be ambiguous to learners; that is, instead of perceiving recasts as containing corrective feedback, learners might see them simply as literal or semantic repetitions without any corrective element (Long, in press; Lyster & Ranta, 1997). This study investigates learners'…

This article describes the use of touch as a strategy to teach children with multiple handicaps. Touch cues help children to anticipate events and to interpret information from the environment. Caregivers should first observe the child's existing repertoire of movements, and then create touch cues that build upon the child's preferred…

Thirty introductory psychology students were randomly divided into two groups. The control group took a standard in-class printed examination. The treatment group was provided with both exam booklets and individual sets of audio equipment on which exam questions were recorded. The treatment group scored significantly higher. (NHM)

This paper extended the investigation of the concept of negation into actual classroom environments by ascertaining the frequency with which pupils at three different elementary school academic levels are expected to process teacher-initiated oral statements (the pupils' aural school environment) which contain selected negation elements.…

The high school version of the Watson-Barker Listening Test was developed in response to the need for a listening test appropriate for high school students. The test was comprised of conversations that would normally occur in either the high school setting or in the home and was developed in two different versions. The test consists of five…

Eight 2-month-old Japanese infants and their 25- to 30-year-old mothers participated in an investigation of the characteristics of pleasure vocalization, correlations in pitch and duration between motherese and pleasure vocalizations, and similarities in the melody types of motherese and pleasure vocalizations. Motherese, infant vocalizations…

A model and a technique developed by Wing and Kristofferson (1973) decomposes variance of timing into that putatively due to a central timekeeper (a clock) and that due to implementation of movement through the motor system. A patient with unilateral cerebellar damage, when attempting to tap out a regular series of intervals, showed a large…

Educable mental retardates and normal grade school students were presented seven classes of materials in both visual and auditory modalities for the determination of immediate memory span thresholds. Major conclusions included auditory presentation produces higher thresholds than visual, and retarded children may employ different processing…
