Performance Monitoring and Cognitive Inhibition during a Speech-in-Noise Task in Older Listeners.

The goal of this study was to examine the effect of hearing loss on theta and alpha electroencephalography (EEG) frequency power measures of performance monitoring and cognitive inhibition, respectively, during a speech-in-noise task. It was hypothesized that hearing loss would be associated with an increase in the peak power of theta and alpha frequencies toward easier conditions compared to normal hearing adults. The shift would reflect how hearing loss modulates the recruitment of listening effort to easier listening conditions.

Impact of Effortful Word Recognition on Supportive Neural Systems Measured by Alpha and Theta Power.

Objectives: The goal of this study was to use theta and alpha electroencephalography (EEG) frequency power and self-report measures to examine performance monitoring, cognitive inhibition, and perceived effort required for speech understanding in noise. It was hypothesized that with a linear increase in word recognition task difficulty, there would be a linear increase in listening effort and word recognition performance would decrease in the challenging conditions. In addition, theta and alpha power would have an inverted U-shape across easy to challenging listening conditions.

Challenging the Link Between Early Childhood Television Exposure and Later Attention Problems: A Multiverse Approach.

In 2004, Christakis and colleagues published findings that he and others used to argue for a link between early childhood television exposure and later attention problems, a claim that continues to be frequently promoted by the popular media. Using the same National Longitudinal Survey of Youth 1979 data set ( = 2,108), we conducted two multiverse analyses to examine whether the finding reported by Christakis and colleagues was robust to different analytic choices. We evaluated 848 models, including logistic regression models, linear regression models, and two forms of propensity-score analysis.

Registered Replication Report: Dijksterhuis and van Knippenberg (1998).

Dijksterhuis and van Knippenberg (1998) reported that participants primed with a category associated with intelligence ("professor") subsequently performed 13% better on a trivia test than participants primed with a category associated with a lack of intelligence ("soccer hooligans"). In two unpublished replications of this study designed to verify the appropriate testing procedures, Dijksterhuis, van Knippenberg, and Holland observed a smaller difference between conditions (2%-3%) as well as a gender difference: Men showed the effect (9.3% and 7.

Validation of the Pictorial Infant Communication Scale for preschool-aged children with autism spectrum disorder.

Joint attention, or the shared focus of attention between objects or events and a social partner, is a crucial milestone in the development of social communication and a notable area of deficit in children with autism spectrum disorder. While valid parent-report screening measures of social communication are available, the majority of these measures are designed to assess a wide range of behaviors. Targeted assessment of joint attention and related skills is primarily limited to semi-structured, examiner-led interactions, which are time-consuming and laborious to score.

The effects of working memory on brain-computer interface performance.

Objective: The purpose of the present study is to evaluate the relationship between working memory and BCI performance.

Methods: Participants took part in two separate sessions. The first session consisted of three computerized tasks.

Parent report of child's health-related quality of life after a primary-care-based weight management program.

Background: Health-related quality of life (HRQoL) has been recognized as an important target and health outcome in obesity research. The current study aimed to examine HRQoL in overweight or obese children after a 10-week primary-care-based weight management program, Parent-Led Activity and Nutrition for Healthy Living, in southern Appalachia.

Methods: Sixty-seven children (ages 5-12 years) and their caregivers were recruited from four primary care clinics, two of which were randomized to receive the intervention.

Comparative efficacy of LEAP, TEACCH and non-model-specific special education programs for preschoolers with autism spectrum disorders.

LEAP and TEACCH represent two comprehensive treatment models (CTMs) that have been widely used across several decades to educate young children with autism spectrum disorders. The purpose of this quasi-experimental study was to compare high fidelity LEAP (n = 22) and TEACCH (n = 25) classrooms to each other and a control condition (n = 28), in which teachers in high quality special education programs used non-model-specific practices. A total of 198 children were included in data analysis.

Longitudinal comparison of early speech and language milestones in children with cleft palate: a comparison of US and Slovak children.

The purpose of this study was to compare early speech and language development of children with and without cleft lip and/or palate (CLP) in the US and Slovakia from 6 to 24 months of age. Thirty-two children from the US (eight with CLP and eight noncleft) and Slovakia (eight with CLP and eight noncleft) participated in this study. The children were videotaped at four time points for 30 minutes during mother-child interaction with play sets controlled for early-developing sounds in each language.

Seasonal association of thrombotic thrombocytopenic purpura.

Background: Thrombotic thrombocytopenic purpura (TTP), a thrombotic microangiopathy, is a clinical diagnosis, characterized by microangiopathic hemolytic anemia and thrombocytopenia without another likely explanation. Some initiators of the disease are well represented in the literature, such as certain drugs, malignancies, and viral illness; however, there are less objective factors still being investigated, with references to hormonal, stress, and seasonal variations considered anecdotally. A better insight of these factors would aid in understanding the pathophysiology of the disease.
