Definitions

  • This invention relates to a method and apparatus for improving mental focus, visceral perception and bilateral psychomotor skills.

  • heartbeat sensations are commonly assessed using tasks that require individuals to judge simultaneity of heartbeat and tones. This has resulted in several major studies in recent years. However, interest in this area dates back many decades, though in the realm of psychology, few are the investigators whom have examined empirically the relationship between perception of autonomic arousal and emotional state.
  • a method of investigating visceral perception in a subject which comprises detecting a visceral physiological event, for example heartbeat, detecting psychomotor activity of the subject, and analysing the occurrence of psychomotor activity relative to that of the visceral physiological event.

  • the apparatus is physically configured to detect psychomotor events from a plurality of sources, especially from parallel sources from each side of the (bilateral) subject.
  • the invention is based on the realisation that by the provision of appropriate hardware and software, it is possible to monitor, quantify and entrain visceral perception skills through the synchronize performance of a simple psychomotor task which promotes bilateral brain activity.

This is conveniently done by calculating the beat-to-beat phase shift between the visceral physiological event, (heartbeat), and the psychomotor task event (bilateral hand pressing of a switch). Brain laterality is indirectly monitored and quantified from differences in visceral perception performance while each side of the brain 5 is activated.

  • the PC serial port interface may be configured to carry out the first signal processing step described below within an integrated circuit in the interface, and the resulting signal can then be fed into the PC.
  • the PC is programmed to calculate the relative times for R, L, and H, preferably using a low level language software application that enables very precise cycle clock measurements.
  • Another software-based module uses an algorithm to calculate the absolute shift in time between the hand press events (L or R) and the actual heartbeat (H).
  • the application detects the closest H event before or after the hand press event. It then establishes the shortest shift period in absolute value from the two.
  • HL or HR calculated periods are recorded in a database facility that holds all the values of HL, HR and HH of a working session (as explained further below).
  • the application quantifies MEAN & SD, (standard deviation), for HL and HR values to provide parametric measurements of the "Accuracy", (A), of heart beat detection for L and R and their relative degrees of "Dispersion” (D).
  • the apparatus When using the apparatus, a user may not guess all the heartbeats during the session and miss some of them. However, the total number of H with guessed response, (L or R), can be measured by an off-line processing module, which calculates the percentage of the total number of actual physiological heartbeats, (No. (H)), that the user attempted to guess during the whole session. This enables a marker of the "Effort" (E) of heartbeat detection skills to be calculated, which can then be taken into account for a final evaluation of performance.
