Meditation practices with a wider attentional focus, such as Shoonya meditation, are associated with longer intrinsic neural timescales (INTs) in the brain, measured as the autocorrelation window (ACW) of EEG signals, compared to practices with a narrower focus like Mantra or Vipassana meditation. The study compared three groups of highly proficient practitioners from different traditions and a meditation-naïve control group. The results indicate a correspondence between the width of attentional scope and the duration of neural temporal windows, suggesting that subjective attentional width relates to objective neural activity patterns.
Altered experiences of time and space are linked to general symptoms and basic self-disorders in people with schizophrenia spectrum disorder. Self-disturbance acts as a key mediator through which fundamental time-space disruptions influence perceptual changes as well as negative, positive, and general symptoms. Data were collected at three medical expert centers using semi-structured phenomenological interviews and analyzed with network and mediation methods.
