Working memory is believed to play a central role in almost all domains of higher cognition, yet the specific mechanisms involved in working memory are still fiercely debated. We describe a neuroimaging experiment with functional magnetic resonance imaging (fMRI) and a companion behavioral experiment, and in both we seek to adjudicate between…

This paper describes My Science Tutor (MyST), an intelligent tutoring system designed to improve science learning by students in 3rd, 4th and 5th grades (7 to 11 years old) through conversational dialogs with a virtual science tutor. In our study, individual students engage in spoken dialogs with the virtual tutor Marni during 15 to 20 minute…

A persistent problem for teachers in English as a Second Language (ESL) situations concerns students who speak their shared common language instead of English in the classroom. Considering the inherent difficulty of the speaking skill, this is understandable. Learners often prefer to interact socially in their native language, allowing them to…

This study assessed, in a sample of 98 adult native speakers of Dutch, how their lexical skills and their speaking proficiency varied as a function of their age and level of education and profession (EP). Participants, categorized in terms of their age (18-35, 36-50, and 51-76 years old) and the level of their EP (low versus high), were tested on…

This article reports the findings of a study investigating factors contributing to the speaking-in-class anxiety of a group of 313 Chinese ESL first-year university students in Hong Kong. Results using the Foreign Language Classroom Anxiety Scale (FLCAS) of Horwitz et al. reveal five factors leading to the group's speaking-in-class anxiety. The…

The number of children receiving cochlear implants (CIs) with significant disabilities in addition to their deafness has increased substantially. Unfortunately, children with additional disabilities receiving CIs have largely been excluded from studies on cochlear implant outcomes. Thus limited data exists on outcomes in this population to guide…

This study examined two types of classroom assessment events, the more closed convergent assessments (CA) versus the more open-ended divergent assessments (DA), to see if they influence learners differently in terms of motivation and learning strategies. Participants were 105 college freshmen in Taiwan with the same instructor placed under one…

Learning about foreign language (FL) cultures is becoming an important objective in the FL curricula and national standards of different countries throughout the world. The purposes of the study were to examine the effects of the cultural portfolio project on (1) students' specific aspects of development of cultural knowledge and change in…

This article introduces The RULER Approach ("RULER") to social and emotional learning, with a particular focus on its Feeling Words Curriculum. Through this curriculum, RULER contributes to the ultimate goals of an English language arts education--preparing students to achieve personal, social, and academic goals and to be engaged and contributing…

Background: Mechanical ventilation is commonly used during the acute management of cervical spinal cord injury, and is required on an ongoing basis in the majority of patients with injuries at or above C3. However, to date there have been limited systematic investigations of the options available to improve speech while ventilator-assisted…

Background: Stuttering is prone to strike during speech initiation more so than at any other point in an utterance. The use of auditory feedback (AAF) has been found to produce robust decreases in the stuttering frequency by creating an electronic rendition of choral speech (i.e., speaking in unison). However, AAF requires users to self-initiate…

Research evidence shows that a career dialogue is a central part of any powerful learning environment for career learning. In vocational education and training, there are three important parties in this dialogue: the student, the teacher and the mentor from practice. In this paper the communication between these parties is investigated in…

This article presents an inquiry into conversations that academic teachers have about teaching. The authors investigated to whom they talk and the forms that these conversations take. The findings indicate that most teachers rely on a small number of significant others for conversations that are characterised by their privacy, by mutual trust and…

Perceptual integration of the sound directly emanating from the source with reflections needs both temporal storage and correlation computation of acoustic details. We examined whether the temporal storage is frequency dependent and associated with speech unmasking. In Experiment 1, a break in correlation (BIC) between interaurally correlated…

Disfluencies can affect language comprehension, but to date, most studies have focused on disfluent pauses such as "er". We investigated whether disfluent repetitions in speech have discernible effects on listeners during language comprehension, and whether repetitions affect the linguistic processing of subsequent words in speech in ways which…
