The aim of the present study was to compare the types of exploratory procedures employed by children when exploring bidimensional tactile patterns and correlate the use of these procedures with the children's shape drawing performance. 18 early blind children, 20 children with low vision and 24 age-matched blindfolded sighted children aged…

In early childhood and primary (PreK-2) grades, subitizing is a critical skill that helps children meet early mathematics standards. Discover ways teachers can infuse this critical skill into their math curriculum.

Evidence that learning rule-based (RB) and information-integration (II) category structures can be dissociated across different experimental variables has been used to support the view that such learning is supported by multiple learning systems. Across 4 experiments, we examined the effects of 2 variables, the delay between response and feedback…

Judgments of learning (JOLs) are sometimes influenced by factors that do not impact actual memory performance. One recent proposal is that perceptual fluency during encoding affects metamemory and is a basis of metacognitive illusions. In the present experiments, participants identified aurally presented words that contained inter-spliced silences…

Visual tracking of multiple objects in a complex scene is a critical survival skill. When we attempt to safely cross a busy street, follow a ball's position during a sporting event, or monitor children in a busy playground, we rely on our brain's capacity to selectively attend to and track the position of specific objects in a dynamic scene. This…

The international Education for All initiative to bring about universal primary education has resulted in large enrollment increases in lower income countries but with limited outcomes. Due to scarcity in material and human resources, all but the better off often fail to learn basic skills. To improve performance within the very limited capacities…

Background: The ability to think analogically is central to the process of learning and understanding reality and there is a broad consensus among researchers that we can improve this ability. Immigrants who have emigrated from developing to developed countries tend to experience tremendous challenges in their early years as immigrants. Their…

A perturbation paradigm was employed to assess 3- and 6-month-old infants' and their mothers' sensitivity to a 3-s temporal delay implemented in an ongoing televised interaction. At both ages, the temporal delay affected infant but not maternal behavior and only when implementing the temporal delay in maternal (Experiment 1, N = 64) but not infant…

Distinct sensory processing (SP) subtypes in autism have been reported previously. This study sought to replicate the previous findings in an independent sample of thirty children diagnosed with an Autism Spectrum Disorder. Model-based cluster analysis of parent-reported sensory functioning (measured using the Short Sensory Profile) confirmed the…

The primary focus of this research study was to examine the benefit of a using a multimodal approach to speech sound correction with preschool children. The approach uses the auditory, tactile, and kinesthetic modalities and includes a unique, interactive visual focus that attempts to provide a visual representation of a phonemic category. The…

Audiovisual speech consists of overlapping and invariant patterns of dynamic acoustic and optic articulatory information. Research has shown that infants can perceive a variety of basic auditory-visual (A-V) relations but no studies have investigated whether and when infants begin to perceive higher order A-V relations inherent in speech. Here, we…

The current study investigated early temperament in 54 infants at familial high-risk of ASD and 50 controls. Parental report of temperament was assessed around 7, 14 and 24 months of age and diagnostic assessment was conducted at 3 years. The high-risk group showed reduced "Surgency" at 7 and 14 months and reduced "Effortful Control" at 14 and 24…

The goals of our study were to (a) compare agreement between autism spectrum disorder diagnosis and outcome of the Modified Checklist for Autism in Toddlers and Parents Evaluation of Developmental Status in a sample of toddlers and (b) examine specific concerns noted for toddlers who screened negative on the Modified Checklist for Autism in…

Infant brain development is a dynamic process dependent upon endogenous and exogenous stimulation and a supportive environment. A critical period of brain and neurosensory development occurs during the third trimester and into the "fourth" trimester (first three months of life). Disruption, damage, or deprivation in the infant's social and…

While much developmental research has focused on the strategies that children employ to recognize faces, less is known about the principles governing the organization of face exemplars in perceptual memory. In this study, we tested a novel, child-friendly paradigm for investigating the organization of face, bird and car exemplars. Children ages…
