Research on the impact of auditory information on visual anticipation in tennis suggests that the intensity of racket-ball-contact sounds systematically biases estimates of the ball's speed, thereby influencing anticipatory judgments. Here we examined whether the effect of auditory information on visual anticipation is dependent on the…

Background: To overcome variability in spoken language, listeners utilize various types of context information for disambiguating speech sounds. Context effects have been shown to be affected by cognitive load. However, previous results are mixed regarding the influence of cognitive load on the use of context information in speech perception.…

Listening to speech in a noisy background is difficult for everyone. While such listening has historically been considered mainly in the context of auditory processing, the role of cognition has attracted considerable interest in recent years. This has been particularly true in the context of life-span research and the comparison of younger and…

Listeners perceive speech sounds relative to context. Contextual influences might differ over hemispheres if different types of auditory processing are lateralized. Hemispheric differences in contextual influences on vowel perception were investigated by presenting speech targets and both speech and non-speech contexts to listeners' right or left…

Event Related Potentials (ERPs) were recorded from Spanish-English bilinguals (N = 10) to test pre-attentive speech discrimination in two language contexts. ERPs were recorded while participants silently read magazines in English or Spanish. Two speech contrast conditions were recorded in each language context. In the "phonemic in English"…

The effect of cognitive load (CL) on speech recognition has received little attention despite the prevalence of CL in everyday life, e.g., dual-tasking. To assess the effect of CL on the interaction between lexically-mediated and acoustically-mediated processes, we measured the magnitude of the "Ganong effect" (i.e., lexical bias on phoneme…

Noise is a pervasive and influential source of stress. Whether through the acute effects of impulse noise or the chronic influence of prolonged exposure, the challenge of noise confronts many who must accomplish vital performance duties in its presence. Although noise has diffuse effects, which are shared in common with many other chronic forms of…

Psychophysical studies are reported examining how the context of recent auditory stimulation may modulate the processing of new sounds. The question posed is how recent tone stimulation may affect ongoing performance in a discrimination task. In the task, two complex sounds occurred in successive intervals. A single target component of one complex…

When presented with alternating low and high tones, listeners are more likely to perceive 2 separate streams of tones ("streaming") than a single coherent stream when the frequency separation ([delta]f) between tones is greater and the number of tone presentations is greater ("buildup"). However, the same large-[delta]f sequence reduces streaming…

Harmonic priming studies have shown that a musical context with its tonal center influences target chord processing. In comparison with targets following baseline contexts, which do not establish a specific tonal center, processing is facilitated for a strongly related target functioning as the tonic, but inhibited for unrelated (out-of-key) and…

Visual speech cues presented in synchrony with discrepant auditory speech cues are usually combined to a surprisingly clear unitary percept that corresponds with neither of the two sensory inputs (the McGurk illusion). This audiovisual integration process is commonly believed to be highly autonomous and robust to cognitive intervention, unlike the…
