Children diagnosed with an Attention Deficit Hyperactivity Disorder (ADHD) often exhibit impulsivity and timing difficulties. Here, we investigated whether children (mean age = 9.9 years) with combined type ADHD, comprising both hyperactive-impulsive and inattentive symptoms, could use the temporal predictability of an event to help inhibit impulsive behaviour.

Whole lung lavage (WLL) involves the instillation of fluid into the lungs to wash out silica particles and disease-causing inflammatory cells. This study aimed to determine the feasibility, safety, and possible benefit of WLL in patients with artificial stone silicosis.

- Phenomenology highlights that individuals with schizophrenia experience a disrupted sense of time and self, leading to fragmented temporal experiences.
- The study involved 41 patients with schizophrenia and 43 neurotypical participants, who were tasked with responding to visual targets following an initial warning signal and varying waiting periods.
- Findings showed that while neurotypicals improved response times with longer waiting periods, this benefit diminished for patients, suggesting that their impaired temporal processing is linked to their disordered sense of self.
Timing and motor function share neural circuits and dynamics, which underpin their close and synergistic relationship. For instance, the temporal predictability of a sensory event optimizes motor responses to that event. Knowing when an event is likely to occur lowers response thresholds, leading to faster and more efficient motor behavior though in situations of response conflict can induce impulsive and inappropriate responding.
