Purpose: Speech shadowing experiments were conducted to test whether alignment (inadvertent imitation) to voice onset time (VOT) can be influenced by visual speech information. Method: Experiment 1 examined whether alignment would occur to auditory /pa/ syllables manipulated to have 3 different VOTs. Nineteen female participants were asked to…

In 3 experiments, we examined Perruchet, Cleeremans, and Destrebecqz's (2006) double dissociation of cued reaction time (RT) and target expectancy. In this design, participants receive a tone on every trial and are required to respond as quickly as possible to a square presented on 50% of those trials (a partial reinforcement schedule).…

This study aimed to isolate the conditions under which aversive stimulation is experienced as more or less discomforting/unpleasant. Discomfort was induced by playing loud noises through headphones while participants performed computer tasks. We employed 4 main conditions. Condition 1: the acceptance-based protocol (ACT), intended to integrate…

This research examined the effects of bimodal audiovisual and unimodal visual stimulation on infants' memory for the visual orientation of a moving toy hammer following a 5-min, 2-week, or 1-month retention interval. According to the intersensory redundancy hypothesis (L. E. Bahrick & R. Lickliter, 2000; L. E. Bahrick, R. Lickliter, & R. Flom,…

The processes of infant word segmentation and infant word learning have largely been studied separately. However, the ease with which potential word forms are segmented from fluent speech seems likely to influence subsequent mappings between words and their referents. To explore this process, we tested the link between the statistical coherence of…

Children between the ages of 5 and 12 years were tested with dichotic listening tests utilizing single syllable words and random presentations of digits. They produced a higher prevalence of left ear dominance than expected, especially among right-handed children when tested with words. Whether more children demonstrate the LEA because of right…

Reciprocal peer tutoring can be an effective supplement to teacher-led instruction, but students need to have the tutoring skills necessary to teach their peers successfully. Previous studies have addressed the challenge of providing essential information to a naive tutor, allowing for correct modeling and feedback. The present study compared…

This paper explores the convergence of technology and the arts within the context of aurality in the twenty-first century. Jenkins argued this is taking place within a cultural convergence, whereby a vernacular culture focused upon participation, creation, performance, and migratory behaviour of media audiences has emerged. The developing changes…

We investigate non-verbal communication through expressive body movement and musical sound, to reveal higher cognitive processes involved in the integration of emotion from multiple sensory modalities. Participants heard, saw, or both heard and saw recordings of a Stravinsky solo clarinet piece, performed with three distinct expressive styles:…

We report a series of experiments designed to demonstrate that the presentation of a sound can facilitate the identification of a concomitantly presented visual target letter in the backward masking paradigm. Two visual letters, serving as the target and its mask, were presented successively at various interstimulus intervals (ISIs). The results…

The time-course of representing others' perspectives is inconclusive across the currently available models of ToM processing. We report two visual-world studies investigating how knowledge about a character's basic preferences (e.g. "Tom's favourite colour is pink") and higher-order desires (his wish to keep this preference secret) compete to…

Two experiments were conducted to examine (a) the relationship between the structural characteristics (i.e., bout duration, inter-response time [IRT], pitch, and energy) and overall duration of vocal stereotypy, and (b) the effects of auditory stimulation on the duration and temporal structure of the behavior. In the first experiment, we measured…

Pervasive developmental disorder not otherwise specified (PDD-NOS) represents up to two-thirds of autism spectrum disorders; however, it is usually described in terms of the symptoms not shared by autism. The study explores processing of neutral and emotional human stimuli (by auditory, visual and multimodal channels) in children with PDD-NOS (n =…

This within-subjects experiment tested the relationship between the premotor (cognitive) component of reaction time (RT) to a missing stimulus and parameters of the omitted stimulus potential (OSP) brain wave. Healthy young men (N = 28) completed trials with an auditory stimulus that recurred at 2 s intervals and ceased unpredictably. Premotor RT…

Purpose: To determine the aerodynamic and acoustic effects due to a sudden change from chest to falsetto register or vice versa. It was hypothesized that the continuous change in subglottal pressure and flow rate alone (pressure-flow sweep [PFS]) can trigger a mode change in the canine larynx. Method: Ten canine larynges were each mounted over a…
