This research study is an experimental study focusing on auditory perception. The objectives of this research are (1) to evaluate acoustical characteristics of the classroom (2) to assess acoustical perceptions of students with different educational backgrounds. The subjects of this study consisted of 54 science students and 53 art students. The…

Purpose: For listeners with single-sided deafness, a cochlear implant (CI) can improve speech understanding by giving the listener access to the ear with the better target-to-masker ratio (TMR; head shadow) or by providing interaural difference cues to facilitate the perceptual separation of concurrent talkers (squelch). CI simulations presented…

Purpose: In situations with a competing talker, lexical properties of words in both streams affect the recognition of words in the to-be-attended target stream. In this study, we tested whether these lexical properties also influence the type of errors made by listeners across the adult life span. Method: Errors from a corpus collected by Helfer…

Prior studies have emphasized the contribution of aberrant amygdala structure and function in social aspects of autism. However, it remains largely unknown whether amygdala dysfunction directly impairs visual attention and exploration as has been observed in people with autism spectrum disorders (ASD). Here, gaze patterns were directly compared…

Listeners are known to track statistical regularities in speech. Yet, which temporal cues are encoded is unclear. This study tested effects of talker-specific habitual speech rate and talker-independent average speech rate (heard over a longer period of time) on the perception of the temporal Dutch vowel contrast /?/-/a:/. First, Experiment 1…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

Background: To date, the immediate effects of a semi-occluded vocal tract (SOVT) configuration have been thoroughly demonstrated. However, it is not yet sufficiently confirmed whether a therapy programme (i.e. longer than one session) using SOVT exercises leads to an enhanced phonation and improved vocal quality. Aims: The aim of this study was to…

Department chairs serve a vital function at community colleges. They are middle managers, mid-level leaders, and faculty members. They serve a unique position within the organization because they interact with nearly every unit: academics affairs, student affairs, senior administrators and students. At a time when professional organizations are…

Purpose: Pitch reception poses challenges for individuals with cochlear implants (CIs), and adding a hearing aid (HA) in the nonimplanted ear is potentially beneficial. The current study used fine-scale synthetic speech stimuli to investigate the bimodal benefit for lexical tone categorization in Mandarin-speaking kindergarteners using a CI and an…

As school districts, major cities, and entire states in the United States adopt personalized learning as a reform strategy focused on the co-construction of learning opportunities between teachers and students, educators face shifting roles. This study examined the roles of teachers in personalized learning environments within a policy context of…

Typically developing (TD) infants adapt to the social world in part by shifting the focus of their processing resources to the relevant aspects of a visual scene. Any impairment in visual orienting may therefore constrain learning and development in domains such as language. However, although something is known about visual orienting in infants at…

As spatial languages, sign languages rely on spatial cognitive processes that are not involved for spoken languages. Interlocutors have different visual perspectives of the signer's hands requiring a mental transformation for successful communication about spatial scenes. It is unknown whether visual-spatial perspective-taking (VSPT) or mental…

In this study, we examined the efficacy of gestures for the acquisition of L2 segmental phonology. Despite teachers' frequent use of gestures in the classroom to teach pronunciation, the field lacks empirical support for this practice. We attempted to fill this gap by investigating the effects of handclapping on the development of L2 Japanese…

This study emanates from behaviorism theory and cooperative paradigm, which evaluates the effects of parents' daily household activities regarding littering on children through participatory action research approach. Litter is a socio-cultural environmental issue that degrade environment. Additionally, pre-packed foods and other disposable items…

Working memory (WM) is a significant predictor of academic performance. Emerging empirical evidence has shown that WM can be improved via computerized cognitive training (CCT). Though studies have shown that CCT can improve WM in typical and atypical populations, little is known regarding the efficacy of implementing CCT within a school setting.…
