The current study examined cognitive effects of two pathways of second language (L2) acquisition longitudinally in Chinese speakers learning English in an L2-dominant environment. Thirty-nine participants who attended an intensive 10-week English course (L2-instruction group) were compared to 38 participants who attended regular university courses…

Listeners can access information about a speaker such as age, gender identity, socioeconomic status, and their linguistic background upon hearing their speech. However, it is still not clear if listeners use these factors to assess speakers' speech. Here, an audio-visual (matched-guise) test is used to measure whether listeners' accentedness…

Purpose: The aim of the study was to investigate the effects of specific acoustic patterns on word learning and segmentation in 8- to 11-year-old children and in college students. Method: Twenty-two children (ages 8;2-11;4 [years;months]) and 36 college students listened to synthesized "utterances" in artificial languages consisting of…

Smartwatches may provide a natural, portable, and unobtrusive strategy by which to support directive-following for individuals with autism spectrum disorders (ASD). A mentor can send visual supports (e.g., photographs, videos, text) "just-in-time" (JIT) to a learner's smartwatch. This may reduce the need for extraneous face-to-face…

Prediction-based theories posit that interlocutors use prediction to process language efficiently and to coordinate dialogue. The present study evaluated whether listeners can use spatial deixis (i.e., "this," "that," "these," and "those") to predict the plurality and proximity of a speaker's upcoming…

According to prediction-based learning theories, erroneous predictions support learning. However, empirical evidence for a relation between prediction error and children's language learning is currently lacking. Here we investigated whether and how prediction errors influence children's learning of novel words. We hypothesized that word learning…

Although the good behavior game (GBG) has a long empirical record for effectively decreasing inappropriate student behavior, there are fewer studies that have targeted improving appropriate behavior. This article describes why and how the GBG can be used by teachers across grade levels and situations to increase student appropriate behavior and…

We used a contingent acoustical feedback procedure to increase appropriate walking and decrease toe walking exhibited by a young boy with autism. After a pre-treatment screening assessment suggested that toe walking was maintained by automatic reinforcement, we paired an auditory stimulus (i.e., a clicking sound) with access to a preferred item to…

Objectives: Increased listening effort in school-age children with hearing loss (CHL) could compromise learning and academic achievement. Identifying a sensitive behavioral measure of listening effort for this group could have both clinical and research value. This study examined the effects of signal-to-noise ratio (SNR), hearing loss, and…

Introduction: The current work presents a framework of motoric complexity where stimuli differ according to movement elements across a sound sequence (i.e., consonant transitions and vowel direction). This framework was then examined in children with childhood apraxia of speech (CAS), other speech sound disorders (SSDs), and typical development…

Purpose: The pupil dilation response is sensitive not only to auditory task demand but also to cognitive conflict. Conflict is induced by incompatible trials in auditory Stroop tasks in which participants have to identify the presentation location (left or right ear) of the words "left" or "right." Previous studies demonstrated…

Early vocabulary knowledge is vital for later reading comprehension and academic success. Studies have found that augmenting explicit teaching of word meanings with nonverbal visual aids, particularly pictures and gestures, assists young learners in building rich lexical representations. Research has focused on the effects of visual supports in…

Children with autism spectrum disorder (ASD) display differences in multisensory function as quantified by several different measures. This study estimated the stability of variables derived from commonly used measures of multisensory function in school-aged children with ASD. Participants completed: a simultaneity judgment task for audiovisual…

The "bouba-kiki effect" refers to the correspondence between arbitrary visual and auditory stimuli. Previous studies have demonstrated that neurodevelopmental conditions and sensory impairment affect subjects' performance on the bouba-kiki task. This study examined the bouba-kiki effect in participants with severe-to-profound hearing…

Numerous studies suggest that audiovisual speech influences lexical processing. However, it is not clear which stages of lexical processing are modulated by audiovisual speech. In this study, we examined the time course of the access to word representations in long-term memory when they were presented in auditory-only and audiovisual modalities.…
