TL;DR: A 2026 medRxiv preprint found that nonverbal Theory of Mind (ToM), the ability to infer another person’s beliefs or perspective, varied in 44 adults with post-stroke aphasia and was more closely tied to vascular brain-health markers than to aphasia severity. Key Findings Study group: 44 adults with aphasia after mostly left-hemisphere stroke completed 2 …
TL;DR: A 2026 iScience study found that after 1 hour of training, adults could use a new audio cue for depth judgments, but only about half combined it with a familiar visual cue well enough to improve perceptual precision. Key Findings A total of 78 adults completed the depth task after training on an artificial …
TL;DR: A 2026 Scientific Reports study found that natural images and white noise images produced similar amounts of pareidolia, but they shifted what people thought they saw. Key Findings Healthy adult sample: The study included 81 participants who viewed ambiguous images and drew every illusory object, face, figure, or pattern they perceived. Equal quantity: The …
TL;DR: A 2026 study in Psychological Medicine found that cognitive reserve in non-affective first-episode psychosis was higher with greater genetic predisposition to educational attainment and lower with earlier psychosis onset or family history of psychosis. Key Findings 174 first-episode patients: Researchers analyzed people with non-affective first-episode psychosis, with a mean age of 25.5 years. Educational-attainment …
TL;DR: A 2026 preprint in medRxiv found that 26 autistic children and 25 typically developing peers performed similarly on iPad-based navigation tasks, but the autistic group rated its own sense of direction lower. Key Findings Objective navigation performance did not differ between autistic and typically developing children across path integration, egocentric pointing, mapping, or perspective …
TL;DR: A 2026 medRxiv preprint found that specific AD8 dementia-screening items, especially judgment, repetition, finances, tool use, and daily memory problems, tracked functional and psychosocial vulnerability in 144 Chinese-speaking older adults. Key Findings Small community sample: The cross-sectional study included 144 Chinese-speaking adults with a mean age of 73.1 years. Three AD8 domains: Exploratory factor …
TL;DR: A 2025 study in Computers in Human Behavior linked at-risk problematic gaming to weaker basic working memory, while recreational gaming was linked to better target detection on an attention-control task. Key Findings Three gaming groups: Researchers compared 114 adults who were non-gamers, recreational gamers, or gamers at risk for gaming disorder. Working memory was …
TL;DR: A 2026 study in Neuropsychopharmacology found that decision-making measures from a stop-signal task, especially evidence accumulation, predicted cigarette and cannabis use better than stop-signal reaction time (SSRT), a common estimate of response inhibition. Key Findings More than 1,000 young adults: The analysis used IMAGEN cohort stop-signal task data from 1,256 participants at age 19 …
TL;DR: A 2026 study in Neuropsychiatric Disease and Treatment followed 55 adults after mild-to-moderate COVID-19 and found that neurocognitive test performance improved over time after both Alpha/Delta-era and Omicron-era infections. Key Findings 55-person longitudinal sample: Researchers compared 28 Alpha/Delta-era participants with 27 Omicron-era participants after mild-to-moderate COVID-19. Initial cognitive findings: About half of each group …
TL;DR: A 2026 eNeuro study of 163 people ages 3-25 found that sleep history and age shaped waking electroencephalography (EEG) oscillations, while children with ADHD showed distinct sleep-wake EEG patterns. Key Findings Sleep and development interact to shape wake EEG oscillations: The amount of recent sleep or wakefulness produces age-dependent effects on EEG oscillation amplitude …
