Computer-based Attention Training in Patients With Acquired Brain Injury

Investigates computer based cognitive rehabilitation and training using the N-back task with a Visual Search task as an active control. The overall purpose is to provide (further) evidence about the efficacy (or lack of efficacy) of the N-back task and to find points of convergence and divergence between patients with acquired brain injury and non-impaired subjects.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • subjects should be able to do both task at level at the time of recruitment
  • Informed consent
  • (for brain injured patients) training must not interfere with treatment as usual.
  • (for brain injured patients) no symptoms which hinder testing and training. I.e. aphasia, deafness, tetraplegia etc.

Treatment and study plan

N-back

Behavioral

The N-back task required patients to monitor a continuous sequence of stimuli (in this experiment audio and visual stimuli). Press a button if the current stimulus is the same as that shown N back in the sequence. N increases if performance is good and decreases if performance is poor.

Subjects train for 20 days, 12 blocks a day, 20+N trials per block. That is 240 blocks in total. A minimum of 10 blocks per day counts as a successfully trained day.

Visual Search

Behavioral

The Visual Search task consists of a NxN array of shapes. Press the button if a certain target stimulus is present in this array. N increases if performance is good and decreases if performance is poor.

Subjects train for 20 days, 12 blocks a day, 20+N trials per block. That is 240 blocks in total. A minimum of 10 blocks per day counts as a successfully trained day.

Primary outcomes

  1. Change from baseline Raven's advanced progressive matrices at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.

Secondary outcomes

  1. Change from baseline WAIS-III Working Memory Index at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.

  2. Change from baseline WAIS-III Processing Speed Index at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.

  3. Change from baseline Operation Span at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.

  4. Change from baseline Stroop color-text interference at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.

  5. Change from baseline AMPS at the end of training

    Time frame: within five days after 20 full training days has been completed. Expected 3-6 weeks after baseline.
