Background: The cognitive bases of language impairment in specific language impairment (SLI) and autism spectrum disorders (ASD) were investigated in a novel non-word comparison task which manipulated phonological short-term memory (PSTM) and speech perception, both implicated in poor non-word repetition. Aims: This study aimed to investigate the…

Studies indicate thoughtfully planned chants integrated with shared book reading help young children remember concepts and vocabulary they hear in literature, capture children's imagination, develop their rhyming acuity, and background knowledge, and increase their sense of story structure, understanding of story sequence, phonological awareness,…

Mediated priming refers to the activation of a target (e.g., "stripes") by a prime (e.g., "lion") that is related indirectly via a connecting mediator (e.g., tiger). In previous mediated priming studies (e.g., McNamara & Altarriba, 1988), the mediator was associatively related to the prime. In contrast, pure mediated…

Neurophysiological studies yield contrary results whether attentional problems of patients with attention-deficit/hyperactivity disorder (ADHD) are related to early visual processing deficits or not. Evoked gamma-band responses (GBRs), being among the first cortical responses occurring as early as 90 ms after visual stimulation in human EEG, have…

This study investigated problems that children with visual impairments experience with sexual health education. The participants identified themes that affected their knowledge of sexual health and the need for sexual health education. Strategies that address sexual health issues for individuals with visual impairments are described.

A visual semantic categorization task in English was performed by native English speakers (Experiment 1) and late bilinguals whose first language was Japanese (Experiment 2) or Spanish (Experiment 3). In the critical conditions, the target word was a homophone of a correct category exemplar (e.g., A BODY OF WATER-SEE; cf. SEA) or a word that…

One child with developmental disabilities was taught to mand for attention by saying "excuse me." Treatment effects were extended to multiple training contexts by teaching the participant to attend to naturally occurring discriminative stimuli through differential reinforcement of communication during periods of the experimenter's nonbusy…

In this article the four pedagogical components outlined by the New London Group (1996)--situated practice, overt instruction, critical framing, and transformed practice--were used to focus attention on the case studies of three beginning teachers and their use of digital media (particularly the creation of a digital literacy autobiography) in an…

Merlin C. Wittrock was a friend and colleague who influenced me and many other contemporary mathematics educators on how students learn. In this article I summarize my interactions with Merl beginning in 1965, and how over the following half-century he influenced my thinking on student learning for understanding and, in turn, on how to design…

We compared the primacy of affective versus semantic categorization by using forced-choice saccadic and manual response tasks. Participants viewed paired emotional and neutral scenes involving humans or animals flashed rapidly in extrafoveal vision. Participants were instructed to categorize the targets by saccading toward the location occupied by…

For infants and toddlers demonstrating feeding problems, it is critical to find the basis for the problems to create more pleasurable mealtimes for the child, his or her family members, and caregivers. Feeding difficulties can affect general health, developmental gains, and emotional well-being. Understanding the cause of feeding problems and…

This study used a choice reaction-time paradigm to test the perceived impairment of facial affect recognition in Asperger's disorder. Twenty teenagers with Asperger's disorder and 20 controls were compared with respect to the latency and accuracy of response to happy or disgusted facial expressions, presented in cartoon or real images and in…

The ability to process simultaneously presented auditory and visual information is a necessary component underlying many cognitive tasks. While this ability is often taken for granted, there is evidence that under many conditions auditory input attenuates processing of corresponding visual input. The current study investigated infants' processing…

Learning names for parts of objects can be challenging for children, as it requires overcoming their tendency to name whole objects. We test whether comparing items can facilitate learning names for their parts. Applying the structure-mapping theory of comparison leads to two predictions: (a) young children will find it easier to identify a common…

The purpose of this primarily quantitative study was to compare how young adults with and without intellectual disabilities examine different types of images. Two experiments were conducted. The first, a replication and extension of a classic eye-tracking study (Yarbus, 1967), generated eye gaze patterns and data in response to questions related…
