This study aimed at: (1) determining whether the Concrete-Pictorial-Abstract (CPA) strategy has a positive effect on students' mathematical conceptual understanding (MCU) and students' mathematical representation (MR) on fractions; (2) describing how CPA strategy can improve students' MCU and students' MR on fractions. This research used a mixed…

Cognitive flexibility refers to various processes which enable behaviors to be modified on the basis of a change in the contingencies between stimuli or responses and their associated outcomes. Reversal learning is a form of cognitive flexibility which measures the ability to adjust responding based on a switch in the stimulus--outcome…

Recent research has documented impaired ability to resist interference from visual distractors in individuals with autism spectrum disorder (ASD) and suggests that this phenomenon may be more pronounced in young versus older children (Christ et al., "Neuropsychology" 25(6):690-701, 2011). The present study extends previous findings by…

This article examines children's comprehension of the "get"-passive relative to the "be"-passive in an attempt to systematically compare the acquisition of both types of passives. It discusses the findings of two experiments (a picture-matching task and an act-out task) with children ages 36. Results from the picture-matching…

I conducted a descriptive study consisting of 30 preschool participants with and without disabilities to examine the relation between the 3 bidirectional operants. The bidirectional operants were speaker-as-own-listener cusps, which included bidirectional verbal operants between people, bidirectional self-talk conversational units, and…

Decades-old research has demonstrated the effects of virtual space on perception mostly with adult samples. Little is known about children's ability to utilize spatial-temporal qualities from computerized settings. Past research with primary school children suggested that the ability to utilize spatial-temporal information is crucial for inferring…

Previous findings have shown that individuals with autism spectrum disorder (ASD) evince greater intra-individual variability (IIV) in their sensory-evoked fMRI responses compared to typical control participants. We explore the robustness of this finding with a new sample of high-functioning adults with autism. Participants were presented with…

Understanding the nature of olfactory abnormalities is crucial for optimal interventions in children with autism spectrum disorders (ASD). However, previous studies that have investigated odor identification in children with ASD have produced inconsistent results. The ability to correctly identify an odor relies heavily on visual inputs in the…

Target onsets in dynamically changing displays can be predicted when contingencies exist between different stimulus states over time. In the present study, we examined predictive monitoring when participants searched dynamically changing displays of numbers and colored squares for a color target, a number target, or both. Stimuli were presented in…

The present study investigated whether and how fast young children can use information encoded in morphological markers during real-time event representation. Using the visual world paradigm, we tested 35 adults, 34 5-year-olds and 33 3-year-olds. The results showed that the adults, the 5-year-olds and the 3-year-olds all exhibited eye gaze…

Purpose: This study evaluates the effects of a novel speech therapy program that uses a verbal cue and gamified augmented visual feedback regarding tongue movements to address articulatory hypokinesia during speech in individuals with Parkinson's disease (PD). Method: Five participants with PD participated in an ABA single-subject design study.…

Research on tact acquisition by children with autism spectrum disorder (ASD) has often focused on teaching participants to tact visual stimuli. It is important to evaluate procedures for teaching tacts of nonvisual stimuli (e.g., olfactory, tactile). The purpose of the current study was to extend the literature on secondary target instruction and…

Background: We used two principles of implicit learning, variability and complexity, to train mental orthographic representations in refugee English learners to improve spelling. Methods: Twenty-eight refugees enrolled in a 10-week English class were trained on classroom words using stimuli designed to encourage implicit learning. We contrasted…

Use the practical suggestions offered here to ease the transition when a newcomer emergent bilingual student comes to your school.

Emotional arousal enhances memory encoding and consolidation leading to better immediate and delayed memory. Although the central noradrenergic system and the amygdala play critical roles in both effects of emotional arousal, we have recently shown that these effects are at least partly independent of each other, suggesting distinct underlying…
