Infants as young as 2 months can integrate audio and visual aspects of speech articulation. A shift of attention from the eyes towards the mouth of talking faces occurs around 6 months of age in monolingual infants. However, it is unknown whether this pattern of attention during audiovisual speech processing is influenced by speech and language…

Purpose: The study explored whether visual information improves speech identification in typically developing children with normal hearing when the auditory signal is spectrally degraded. Method: Children (n = 69) and adults (n = 15) were presented with noise-vocoded sentences from the Children's Co-ordinate Response Measure (Rosen, 2011) in…

Purpose: Developmental dyslexia (DD) is commonly thought to arise from phonological impairments. However, an emerging perspective is that a more general procedural learning deficit, not specific to phonological processing, may underlie DD. The current study examined if individuals with DD are capable of extracting statistical regularities across…

Playing the sounds of whales during a class period can initiate the awareness of the role of wonder in education. Students are inspired to avidly collect fascinating facts to pique their interest and open the door to learning science. Indeed, when asked, teachers typically identify their foremost practical challenge as trying to motivate…

The automatic letter-sound integration hypothesis proposes that the decoding difficulties seen in dyslexia arise from a specific deficit in establishing automatic letter-sound associations. We report the findings of 2 studies in which we used a priming task to assess automatic letter-sound integration. In Study 1, children between 5 and 7 years of…

During spatial reorientation, the use of local geometric cues (e.g., corner angles) and global geometric cues (e.g., principal axis) is differentially influenced by enclosure size. Local geometric cues exert more influence in large enclosures compared to small enclosures, whereas the use of global geometric cues is not influenced by changes in…

Infants are thought to be sensitive to frequency in the input as a cue for phonological development. However, linguistic biases such as phonological markedness have been argued to play a role too. Since frequency and markedness are correlated, the two assertions could be different interpretations of data that confound frequency and markedness. In…

Working memory, the system allowing for a simultaneous maintenance and processing of information, is typically conceived as a capacity limited system. A proposed method to transcend its standard maintenance capacity is to maintain multifeature objects, instead of isolated features. Several studies have shown that multifeature memory items are…

Purpose: Previous studies reported that children acquire Cantonese tones before 3 years of age, supporting the assumption in models of phonological development that suprasegmental features are acquired rapidly and early in children. Yet, recent research found a large disparity in the age of Cantonese tone acquisition. This study investigated…

Although many studies have been done on the benefits of parent/teacher-child interactions during shared storybook reading or read'aloud sessions, very few have examined the potential of professional storytellers' oral discourse to support children's vocabulary learning. In those storytelling sessions conducted by professional storytellers, the…

Four experiments were conducted to investigate the interplay between context and tone of voice in the perception of sarcasm. These experiments emphasized the role of contrast effects in sarcasm perception exclusively by means of auditory stimuli whereas most past research has relied on written material. In all experiments, a positive or negative…

Large-scale audiovisual data that measure group learning are time consuming to collect and analyze. As an initial step towards scaling qualitative classroom observation, we qualitatively coded classroom video using an established coding scheme with and without its audio cues. We find that interrater reliability is as high when using visual data…

Purpose: The study investigates whether auditory information affects the nature of intrusion and reduction errors in reiterated speech. These errors are hypothesized to arise as a consequence of autonomous mechanisms to stabilize movement coordination. The specific question addressed is whether this process is affected by auditory information so…

Group work for people who experience voice hearing in the mainstream population has been shown to have various benefits; however, there is little research describing hearing voices groups for people with learning disabilities. This study describes perceptions of a new hearing voices group for people with mild learning disabilities. Semi-structured…

Purpose: This study aims to evaluate the sensitivity of the speech intelligibility index (SII) to the assumed speech dynamic range (DR) in different languages and with different types of stimuli. Method: Intelligibility prediction uses the absolute transfer function (ATF) to map the SII value to the predicted intelligibility for a given stimuli.…
