In first- and second-year algebra classrooms, the all-too-familiar whine of "when are we ever going to use this in real life?" challenges mathematics teachers to find new, engaging ways to present mathematical concepts. The introduction of quadratic equations is typically modeled by describing the motion of a moving object with respect…

The Deaf have often been overlooked when designing informal STEM education and public outreach activities. Astronomers at UC Riverside and teachers at the California School for the Deaf, Riverside (CSDR), have designed an astronomy workshop aimed specifically for the Deaf using the school's on-site sound lab. We have used astronomy for this…

Interactive models of language production predict that it should be possible to observe long-distance interactions; effects that arise at one level of processing influence multiple subsequent stages of representation and processing. We examine the hypothesis that disruptions arising in nonform-based levels of planning--specifically, lexical…

Purpose: A group of 10 prelingually deafened children with cochlear implants (CIs) formed a choir and received 21 months of formal music training. The purpose of this study was to evaluate the singing proficiency of these children. Method: The participants included all choir members (7 girls and 3 boys, mean age of 9.5 years old) who were…

Purpose: The goal of this study was to investigate vowel detection and identification in noise and provide baseline data regarding how vowel perception changed with signal-to-noise ratios. Psychometric functions of vowel detection and identification for 12 American English isolated vowels in long-term speech-shaped noise were examined for young…

Subjective impressions of speech delivery in Autism Spectrum Disorder (ASD) as monotonic or over-precise are widespread but still lack robust acoustic evidence. This study provides a detailed acoustic characterization of the specificities of speech in individuals with ASD using an extensive sample of speech data, from the production of narratives…

Learning always happens from input that contains multiple structures and multiple sources of variability. Though infants possess learning mechanisms to locate structure in the world, lab-based experiments have rarely probed how infants contend with input that contains many different structures and cues. Two experiments explored infants' use of two…

In this study, we propose a hypothesis that domain-general auditory processing, a perceptual anchor of L1 acquisition, can serve as the foundation of successful post-pubertal L2 learning. This hypothesis was tested with 139 post-pubertal L2 immersion learners by linking individual differences in auditory discrimination across multiple acoustic…

The purpose of this study was to investigate the effect of wearing earplugs on classical musicians' pitch perception across three experimental conditions: no earplugs, foam earplugs, and Etymotic earplugs. Participants were graduate and undergraduate music majors attending a large school of music in the southeastern United States (N = 72).…

Purpose: The purpose of this study is to characterize the local (utterance-level) temporal regularities of child-directed speech (CDS) that might facilitate phonological development in Spanish, classically termed a syllable-timed language. Method: Eighteen female adults addressed their 4-year-old children versus other adults spontaneously and also…

Purpose: The aim of this study was to examine the influence of caregivers' reports of family-related environmental confusion--which refers to the level of overstimulation in the family home environment due to auditory and nonauditory (i.e., visual and cognitive) noise--on the relation between child temperament and spoken language outcomes in…

As the majority of people in the world now live in cities, it makes sense to question the state of urban environmental education and how it could be developed going forward. In this article, we suggest a way forward based on the essays written by Finnish university students. The students reflected on their relationship with an environment that is…

In this study, pictures drawn by primary school students about noise were analyzed semiotically. The study was carried out with 20 primary school student volunteers. Research data are the pictures drawn by the children and semi-structured interview records. From the analysis of the students' drawings, three main themes, namely "visual…

Tender Shoots is a randomized controlled trial (RCT) for parents aimed at improving preschool children's oral language skills relevant for later reading. Parents of 72 preschool children (M = 50 months) were randomly assigned to either a Rich Reading and Reminiscing (RRR) condition, a Strengthening Sound Sensitivity (SSS) condition, or an…

Purpose: This study aims to investigate the effects of dysphonic voice on speech intelligibility in Cantonese-speaking adults. Method: Speech recordings from three speakers with dysphonia secondary to phonotrauma and three speakers with healthy voices were presented to 30 healthy listeners (15 men and 15 women; M[subscript age] = 22.7 years) under…
