Purpose: Fragile X syndrome (FXS) is a single-gene disorder characterized by moderate to severe cognitive impairment and a high association with autism spectrum disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD). Atypical visual attention is a feature of FXS, ASD, and ADHD. Thus, studying early attentional patterns in young…

The negative effects of concussion on cognitive and physical performance can linger beyond return to sport and may result in reduced sport performance. The effect of concussion history, including time since concussion and number of concussions, on sport performance is not well understood. The purposes of this study were to examine the effects of…

Mental rotation, a crucial aspect of spatial cognition, can be improved through repeated practice. However, the long-term effects of combining training with non-invasive brain stimulation and its neurophysiological correlates are not well understood. This study examined the lasting effects of a 10-day mental rotation training with high-definition…

This study examined the associations between excessive alcohol intake during adolescence and neurocognitive functioning in young adulthood and whether these relations varied by sex. Participants were working-class Chilean adolescents (N = 692; M[subscript age] 16.0 years; 54.5% female) who provided frequency of past 30-day bingeing and past-year…

Prior research has shown that various types of conventional multiword chunks are processed faster than matched novel strings, but it is unclear whether this processing advantage extends to variant multiword chunks that are less formulaic. To determine whether the processing advantage of multiword chunks accommodates variations in the canonical…

Social interaction depends on turn-taking and adapting to one's conversational partner, yet little is known about the typical and atypical development of these abilities. We investigated this in a longitudinal corpus of spontaneous speech in 64 parent-child dyads: 32 typically developing children (20.27 months at start, six girls, 24 White) and 32…

Although the correlation between general cognitive ability ("g") and performance on speeded cognitive tasks is well-established, there is need for a better understanding of how successive stages of processing contribute to this relationship. Previous research suggests that "g" is primarily associated with the rapidity of…

The goal of the present study was to extend earlier work on the estimation of person theta using maximum likelihood estimation in R by accounting for rapid guessing. This paper provides a modified R function that accommodates person thetas using the Rasch or 2PL models and implements corrections for the presence of rapid guessing or informed…

Accuracy on assessments is commonly studied in education research but response time (RT) is relatively less investigated even though decades of research in cognitive sciences indicate that time can be an important dimension for understanding student learning. To better understand RT and the potentially important relations between accuracy and RT…

The study of socio-cognitive abilities emerged from intelligence research, and their specificity remains controversial until today. In recent years, the psychometric structure of face cognition (FC)--a basic facet of socio-cognitive abilities--was extensively studied. In this review, we summarize and discuss the divergent psychometric structures…

Older adults show a progressive cognitive decline, and although language processing appears to resist advancing age, studies in word retrieval report that elders show important difficulties. Previous research reports that such failures increase from age 70 years, which suggests that during the fourth age word retrieval would exhibit even stronger…

The cognitive advantage (CA) hypothesis claims that multilingualism promotes the development of several basic cognitive capacities. A large number of empirical findings support this hypothesis, but recently there have also been numerous contradictory findings and methodological objections. The present paper extends the investigation of possible…

The speed-accuracy trade-off (SAT) suggests that time constraints reduce response accuracy. Its relevance in observational settings--where response time (RT) may not be constrained but respondent speed may still vary--is unclear. Using 29 data sets containing data from cognitive tasks, we use a flexible method for identification of the SAT (which…

Evidence suggests a relationship between literacy and numeracy skills and cognitive abilities, which could be improved by augmented reality (AR) games. This study aimed to investigate to what degree the performance in a literacy and numeracy skills AR game explains associations between total reaction time (TRT) and educational achievement…

Individual differences in cognitive performance depend on age, skill, and type of task. Nonetheless, whether performance is measured with accuracy (ACC) or with the trade-off between responding speed and accuracy (SAT) could render subtle different relationships. Age and skill might associate more strongly with SAT performance in reasoning tasks,…
