Star Math (SM) is a popular computer adaptive test (CAT) schools use to screen students for academic risk. Despite its popularity, few independent investigations of its diagnostic accuracy have been conducted. We evaluated the diagnostic accuracy of SM based upon vendor provided cut-scores (25th and 40th percentiles nationally) in predicting…

In educational assessment, low engagement is problematic when tests are low stakes for students but have significant consequences for teachers or schools. In the current study, we sought to establish the electroencephalographic (EEG) correlates of engagement and to distinguish engagement from mental effort. Forty university students participated…

Schools across Pennsylvania and around the country are beginning the 2020-2021 school year while COVID-19 remains a threat in widely varying degrees, in different communities, and at different times. Every school that is opening its building to students--part-time or full-time, starting now or later in the school year--needs to contemplate the…

We assessed potential factors associated with "current" or "ever" self-injurious behaviors, reported in the Autism Diagnostic Interview-Revised, among children with autism spectrum disorder (n = 692) from the Study to Explore Early Development. Data on factors examined were obtained from questionnaires, standardized clinical…

As federal mandates continue to emphasize the use of standardized tests, academic research is needed to determine if reading intervention programs are helping to close the achievement gap between struggling readers and their grade level peers. Although previous research indicated that reading intervention can be an effective tool for increasing…

This study investigated the accuracy of brief anxiety scales for non-treatment-seeking youth with autism spectrum disorder. In all, 54 youth (7-17?years; IQ: 67-158) with autism spectrum disorder and their parents completed (a) an expanded version of the Anxiety Disorders Interview Schedule--Child/Parent designed to capture typical and atypical…

The purpose of this non-experimental quantitative study was to investigate the relationship between Pennsylvania's Classroom Diagnostic Tools (CDT) interim assessments and the state-mandated Pennsylvania System of School Assessment (PSSA) and to create linear regression equations that could be used as models to predict student performance on the…

Infant siblings of children with an autism spectrum disorder are at heightened genetic risk to develop autism spectrum disorder. We observed high risk (n?=?35) and low risk (n?=?27) infants at 11?months during free play with a parent. Children were assessed for autism spectrum disorder in toddlerhood. High-risk infants with a later diagnosis…

Studies are needed that examine neurobiological characteristics in high-risk individuals prior to substance use disorder (SUD) development. In this pilot study, 4 adolescent subjects at high risk for SUD (having at least 1 parent with an SUD) were compared with 4 adolescent reference subjects on a cortico-limbic reactivity paradigm, where they…

Maternal immune activity has been linked to children with autism spectrum disorder (ASD). We examined maternal occupational exposure to asthma-causing agents during pregnancy in relation to ASD risk. Our sample included 463 ASD cases and 710 general population controls from the Study to Explore Early Development whose mothers reported at least one…

More than 20?years ago, Minshew and colleagues proposed the Complex Information Processing model of autism in which the impairment is characterized as a generalized deficit involving multiple modalities and cognitive domains that depend on distributed cortical systems responsible for higher order abilities. Subsequent behavioral work revealed a…

Learning-related behaviors are important for school success. Socioeconomic disadvantage confers risk for less adaptive learning-related behaviors at school entry, yet substantial variability in school readiness exists within socioeconomically disadvantaged populations. Investigation of neurophysiological systems associated with learning-related…

With the use of X-ray images, performance in the simultaneous search for two target categories was compared with performance in two independent searches, one for each category. In all cases, displays contained one target at most. Dual-target search, for both categories simultaneously, produced a cost in accuracy, although the magnitude of this…

This study evaluates the utility of perioperative spectral and cepstral acoustic analyses to monitor voice change after thyroidectomy. Perceptual and acoustic analyses were conducted on speech samples (sustained vowel /[alpha]/ and CAPE-V sentences) provided by 70 participants (36 women and 34 men) at four study time points: prior to thyroid…

Universal Institute Charter School, a Title I school in South Philadelphia, uses instructional software for reading that offers diagnostic features so that teachers can quickly identify individual students' needs and respond to them. Because of the success students experienced in the learning support and summer school environments, the program was…
