Twenty 10- to 18-year-old children and adolescents with varying degrees of hearing impairment (HI) and hearing aids (HA), ranging from mild-moderate to severe, produced picture-elicited narratives in a spoken and written version. Their performance was compared to that of 63 normally hearing (NH) peers within the same age span. The participants…

Mathematics is rich in visual representations. Such visual representations are the means by which mathematical patterns "are recorded and analyzed." With respect to "vocabulary" and "symbols," numerous educators have focused on issues inherent in the language of mathematics that influence students' success with mathematics communication.…

The aim of this research was to test whether there is an inherent difficulty in understanding prohibition signs rather than obligation signs. In the experiment conducted, participants decided whether simple car movements presented on a computer screen were allowed or not according to either obligation or prohibition traffic signs. The information…

This study examined attention and memory processes assumed by the social information-processing model to be biased in aggressive children. We also explored whether similar biases were associated with overt and relational aggression. A total of 96 fourth through sixth graders saw videos of overtly and relationally aggressive child actors and…

This study aimed to better understand how metacognitive skills develop in young children aged 5 to 7 years. In particular, we addressed whether developmental changes reflect quantitative or qualitative improvements, and how metacognitive skills change with age and task-specific ability. Previous research into the development of metacognitive…

Young children notice and make use of illustrations in picture books as they read independently as evidenced by statements such as this one from Sarah's retelling of "The Wolf's Chicken Stew": "He couldn't catch him; so he did like this (child folds arms across chest) against the tree". Scholars in the field of children's literature have long…

The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

Instructors of the visually impaired need efficient braille-training methods. This study conducted a preliminary evaluation of a computer-based program intended to teach the relation between braille characters and English letters using a matching-to-sample format with 4 sighted college students. Each participant mastered matching visual depictions…

The goal of this study was to examine the effect of physical modifications on the academic engagement and disruptive behavior of Deaf or Hard-of-Hearing students in self-contained classrooms. Three classrooms at a school for the Deaf were modified after consultation with the classroom teachers. The modifications of the classroom environment…

The purpose of this study was to examine group classroom instruction and the need for in vivo feedback when teaching 11 behavioral therapists how to conduct a brief paired-stimulus preference assessment, when to conduct preference assessments, and how to interpret the data during regular therapy sessions. Group classroom instruction, consisting of…

Many communicative situations present interlocutors with the opportunity to use multiple modalities to establish shared perspectives on conversational referents, a process known as grounding. In the current study, we use a card-matching task to examine how conversational grounding in younger and older adults is influenced both by direct visual…

This study was a systematic extension of Karmali, Greer, Nuzzulo-Gomez, Ross, and Rivera-Valdes (2005) and Ahearn, Clark, MacDonald, and Chung (2007). We investigated the effects of a tact correction procedure on stereotypic vocalizations in 4 children diagnosed with autism who ranged in age from 6 to 16 years. Participants had limited vocal…

Motor involvement in speech perception has been recently studied using a variety of techniques. In the current study, EEG measurements from Cz, C3 and C4 electrodes were used to examine the relative power of the mu rhythm (i.e., 8-13 Hz) in response to various audio-visual speech and non-speech stimuli, as suppression of these rhythms is…

To meet an increasing need to examine the neurophysiological underpinnings of behavior in rats, we developed a behavioral system for studying sensory processing, attention and discrimination learning in rats while recording firing patterns of neurons in one or more brain areas of interest. Because neuronal activity is sensitive to variations in…

The purpose of this experiment is to test whether shift flexibility in kindergarten children is a joint function of rule-usage and inhibition of attention. Sixty-six children were given either a distraction or facilitation condition in a computerized version of the dimensional change card sort task. In the distraction condition, the background of…
