Purpose: Cognitive impairment is one of the most debilitating nonmotor symptoms in Parkinson disease (PD), and its presentation is heterogeneous. One proposed model to explain cognitive variability in PD is the dual-syndrome hypothesis. This hypothesis delineates two cognitive profiles, a "fronto-striatal" profile and a "posterior…

People with autism spectrum conditions (ASC) have difficulties mentally simulating events, perhaps due to a difficulty mentally generating and maintaining a coherent spatial scene -- that is, 'scene construction'. The current study compared scene construction ability between autistic adults (N = 55) and age-, gender- and Intelligence…

Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation used for improving cognitive functions via delivering weak electrical stimulation with a certain frequency. This systematic review and meta-analysis investigated the effects of tACS protocols on cognitive functions in healthy young adults. We identified 56…

A bilingual environment is associated with changes in the brain's structure and function. Some suggest that bilingualism also improves higher-cognitive functions in infants as young as 6-months, yet whether this effect is associated with changes in the infant brain remains unknown. In the present study, we measured brain activity using functional…

Understanding language requires readers and listeners to cull meaning from fast-unfolding messages that often contain conflicting cues pointing to incompatible ways of interpreting the input (e.g., "The cat was chased by the mouse"). This article reviews mounting evidence from multiple methods demonstrating that cognitive control plays…

Previous research links resting frontal gamma power to key developmental outcomes in young neurotypical (NT) children and infants at risk for language impairment. However, it remains unclear whether gamma power is specifically associated with language or with more general cognitive abilities among young children diagnosed with autism spectrum…

Cognitive load theory (CLT), a construct of instructional psychologist John Sweller, has long been a mainstay of educational psychology and university educational technology courses, regionally and internationally. Although aspects of this cognitivist theory have been severely criticised, including its insistence on direct instruction in…

The present study examined the effects of decorative pictures (DP) on cognitive load during learning factual knowledge from texts assessed by physiological proxies, namely pupil dilation and the electroencephalogram (EEG) theta (4-6 Hz) and alpha (8-13 Hz) frequency band power at frontal and parietal electrodes, respectively. In a complete…

Teacher stress and burnout has been associated with low job satisfaction, reduced emotional wellbeing, and poor student learning outcomes. Prolonged stress is associated with emotion dysregulation and has thus become a focus of stress interventions. This study examines emotional interference effects in a group of teachers suffering from high…

Home enrichment plays an important role in shaping children's development. In the current study, we inquired whether home enrichment was associated with pre-schoolers' visual working memory (VWM) function, a critical cognitive system necessary for maintaining information for short periods of time. Home enrichment was assessed using an adapted…

Healthy aging often entails a decline in cognitive and motor functions, affecting independence and quality of life in older adults. Brain stimulation shows potential to enhance these functions, but studies show variable effects. Previous studies have tried to identify responders and non-responders through correlations between behavioral change and…

Emerging scientific knowledge such as the role of epigenetics and neuroplasticity--the brain's capability to constantly rewire with every action, experience, and thought--is fundamentally changing our understanding of the potential impact we can have on our brain. Our brain is formed by our habits in interaction with our body, the environment,…

Intra-individual response time variability (IIRTV) during cognitive performance is increasingly recognized as an important indicator of attentional control (AC) and related brain region function. However, what determinants contribute to preschoolers' IIRTV received little attention. The present study explored the interaction of dopaminergic…

Personality has been found to have significant connections to language. Ranging from impacting narrative style, to informing expectations about others based on linguistic factors such as accent, personality affects both language comprehension and production (Oberlander & Gill, 2004; Van den Brink et al., 2012). However, research in this area…

There is increasing evidence that the authoritarian parenting style has a negative effect on children's executive control, but little is known about the neurobiological mechanism behind this effect, especially the evidence of the resting-state EEG related to children's brain function. The current study explored the relations between authoritarian…
