Caffeine and cycling did not reliably reduce mental fatigue after a Stroop task
A randomized crossover study found people felt more mentally fatigued after sustained cognitive work, regardless of the pre-task intervention. Mental fatigue rose after 30 minutes of Stroop task work, and neither caffeine nor moderate cycling reliably prevented it. Objective vigilance results showed a time-by-treatment interaction, but post-hoc comparisons were not significant. In Differential effects of […]
Dual task walking reduced target fixations and slowed gait in healthy young adults
Adding mental workload narrowed visual exploration, pushed gaze off the path, and made precision stepping less efficient. When healthy young adults walked while doing a cognitive task, they looked less at future stepping targets and more at irrelevant areas. Their gait also slowed, with longer stance times and lower velocity between targets. Cross-stepping appeared more […]
Stereo camera pose tracking beat single camera methods for three dimensional gesture measurement
Two-camera systems produced smaller keypoint errors and better gesture-space overlap than single-camera approaches. A stereo camera approach estimated three-dimensional upper-body gesture keypoints more accurately than single-camera methods. Against optical motion capture, the best stereo method averaged about 50 millimeters of error and showed strong agreement in mapped gesture space. Finger keypoints were more error-prone, with […]
Employee and artificial intelligence collaboration boosts creativity through self-efficacy and performance pressure
Proactive behavior strengthens the confidence pathway and softens the pressure pathway. In this study, collaborating with artificial intelligence at work was linked to higher creativity through two psychological routes: higher self-efficacy and higher performance pressure. Self-efficacy also fed into performance pressure, creating a second, sequential path to creativity. Proactive behavior shifted both routes, amplifying the […]
Depressive symptoms were common in Nigerian pediatric Noma patients, with higher risk in girls
A hospital-based study found heavy mental health burden and clear socioeconomic patterns that should shape care. Depressive symptoms were widespread among children with Noma-related facial disfigurement in Northwestern Nigeria. In this cross-sectional sample, about three in four screened positive for clinically significant depressive symptoms. Risk was higher for girls and linked to parental employment and […]
Higher writing self-efficacy and self-regulated strategies were linked to better English writing in Chinese students
Students who felt more capable and used more writing strategies tended to score higher on essays. A cross-sectional study of Chinese senior high school students learning English found that writing self-efficacy and self-regulated learning strategies were positively related to writing proficiency. Students completed a writing test plus two adapted questionnaires, and their essays were scored […]
People with inflammatory bowel disease intended to seek psychological help, yet most did not
Intent was moderately high, but lack of awareness, self-reliance, and shame kept many from getting support. In Psychological help-seeking behaviours amongst those living with Inflammatory Bowel Disease; A cross-sectional, descriptive, correlational study, people reported moderately high intention to seek professional help for inflammatory bowel disease related negative emotions. Yet 59.8% said they had experienced those […]
Inconsistent condom use among female sex workers in Africa is about 47 percent, tied to violence and harassment
A large synthesis links condom inconsistency to safety, mental health, education, and access. Nearly half of female sex workers in Africa reported inconsistent condom use in a pooled estimate. The review also linked higher odds of inconsistent use to violence, police harassment, depression, and having two or more nonpaying clients. Condom availability and having more […]
Mothers and other caregivers helped infant development, while fathers showed no link in Northern Ghana
More early stimulation activities were tied to better child development scores, but the pattern depended on who did the stimulating. In Northern Ghana, more early stimulation by mothers and other household caregivers was linked with better infant development scores, while fathers’ stimulation was not linked. The journal article Caregivers’ early stimulation behaviors on early child […]
Mental health detention practices silenced Black men’s accounts and increased coercion through racialised risk framing
Professionals described how stigma, racism, and credibility gaps shaped compulsory assessment and treatment decisions. In a UK study of compulsory assessment and treatment, professionals described Black men being treated as inherently risky and less credible during mental health detention decisions. Distress and fear were often reinterpreted as aggression or non-compliance, helping drive rapid escalation to […]
