To investigate the transient evoked otoacoustic emissions (TEOAE) contralateral suppression in neonates at risk for hearing loss, 55 neonates at risk for hearing loss (risk group) and 72 full-term neonates not at such risk (control group) were bilaterally tested. In all neonates, the TEOAE were recorded in two stimulation modes (linear and…

Unexpected stimuli are often able to distract us away from a task at hand. The present study seeks to explore some of the mechanisms underpinning this phenomenon. Studies of involuntary attention capture using the oddball task have repeatedly shown that infrequent auditory changes in a series of otherwise repeating sounds trigger an automatic…

This event-related potential study investigated (i) to what extent incongruence between attention-directing cue and cued target modality affects attentional control processes that bias the system in advance to favor a particular stimulus modality and (ii) to what extent top-down attentional control mechanisms are generalized for the type of…

The seeking of discontinuity in enumeration was recently renewed because Cowan [Cowan, N. (2001). "The magical number 4 in short-term memory: A reconsideration of mental storage capacity." "Behavioral and Brain Sciences," 24, 87-185; Cowan, N. (2005). "Working memory capacity." Hove: Psychology Press] suggested that it allows evaluating the limit…

Three experiments addressed the hypothesis that production factors constrain phonotactic learning in adult English speakers, and that this constraint gives rise to a markedness effect on learning. In Experiment 1, an acoustic measure was used to assess consonant-consonant coarticulation in naturally produced nonwords, which were then used as…

The ill-effect of noise on human performance has been studied by researchers in the fields of cognitive psychology and education for almost a decade. The learning theory Cognitive Information Processing was applied to a new empirical study that builds upon past relevant research on (a) working memory and individuals with learning disabilities, and…

Purpose: This investigation addressed two main questions: (a) How do toddlers' spoken utterances change during the first year of cochlear implant (CI) use? and (b) How do the time-courses for reaching spoken word milestones after implant activation compare with those reported for typically developing children? These questions were explored to…

Purpose: To examine the kinds of explicit and implicit statements generated by school-age children with and without language impairments during comprehension of expository texts and to determine the relationship of these statements to comprehension performance. Method: Forty 4th-grade children with and without language impairments participated in…

Recent spatial cuing studies have shown that detection sensitivity can be increased by the allocation of attention. This increase has been attributed to one of two mechanisms: signal enhancement or uncertainty reduction. Signal enhancement is an increase in the signal-to-noise ratio at the cued location; uncertainty reduction is a reduction in the…

Behavioral reactivity to novel stimuli in the first half-year of life has been identified as a key aspect of early temperament and a significant precursor of approach and withdrawal tendencies to novelty in later infancy and early childhood. The current study examines the neural signatures of reactivity to novel auditory stimuli in 9-month-old…

The work presented here aims to account for the structure of intrasentential code switching between English and Afrikaans within the framework of feature checking theory, a theory associated with minimalist syntax. Six constructions in which verb position differs between English and Afrikaans were analysed in terms of differences in the strength…

Children with primary or "specific" language impairment (PLI) demonstrate subtle deficits in non-linguistic cognitive processing skills that may play a causal or contributing role in PLI. The purpose of this study was to investigate the possibility that short-term treatment of non-linguistic cognitive processing skills improves language abilities…

Abstract Does native language phonology influence visual word processing in a second language? This question was investigated in two experiments with two groups of Russian-English bilinguals, differing in their English experience, and a monolingual English control group. Experiment 1 tested visual word recognition following semantic…

Purpose: This study investigates the ability to understand degraded speech signals and explores the correlation between this capacity and the functional characteristics of the peripheral auditory system. Method: The authors evaluated the capability of 50 normal-hearing native French speakers to restore time-reversed speech. The task required them…

This study examined the developmental course of infants' attentional preferences for 3 types of infant-directed affective intent, which have been shown to be commonly used at particular ages in the first year of life. Specifically, Kitamura and Burnham (2003) found mothers' tone of voice in infant-directed speech is most comforting between birth…
