- Behavioral: filter trainingBehavioral: memory trainingOther: no training (control)
- Registration Number
- NCT03228446
- Lead Sponsor
- German Center for Neurodegenerative Diseases (DZNE)
- Brief Summary
The investigators are interested in how attentional filter training/ distractor inhibition training could influence cognitive functions like working memory, executive control, problem solving, decision making and attentional control.
- Detailed Description
Two different computer based trainings were applied: an attentional filter training and a working memory training.

- Primary Outcome Measures
Name Time Method Improvements in test performance 45min pre / post Working memory and filtering performance (in %), effects of distractor interference and reaction times for trials with and without distractors with 4, 5 \& 6 targets
- Secondary Outcome Measures
Name Time Method Reaction times 45min pre / post Reaction times in each condition
Memory from TAP (Test battery of Attentional Performance) 45min pre / post Working Memory (n-back)
Attention from TAP (Test battery of Attentional Performance) 45min pre / post divided attention, Go-NoGo, Flexibility, Incompatibility, Visual scanning
Performance in repeating numbers 10min pre / post Repeating numbers in forward \& backward conditions
Rey Complex Figure Test 30min pre / post Copying complex figures and reproduce it from memory
Subtest from CANTAB (Cambridge Neuropsychological Test Automated Battery) 10min pre / post Spatial Span Test
Iowa Gambling Task 5min on each training day (1-5) Decision making
Daily Questionnaires 2min on each training day (1-5) Assessing external circumstances of daily influences
Memory performance with distractors among different setsizes 45min pre / post Working memory performance (in %) for trials with 4, 5 \& 6 targets and distractors and averaged performance for all conditions with distractors
Filtering performance with distractors among different setsizes 45min pre / post Filtering performance (in %) for trials with 4, 5 \& 6 targets and distractors and averaged performance for all conditions with distractors
Memory performance without distractors among different setsizes 45min pre / post Working memory performance (in %) for trials with 4, 5 \& 6 targets and averaged performance for all conditions without distractors
Filtering performance without distractors among different setsizes 45min pre / post Filtering performance (in %) for trials with 4, 5 \& 6 targets and averaged performance for all conditions without distractors
Values of distractor inhibition 45min pre / post Distractor inhibition (DIIN) = Mean of conditions without distractors - Mean of conditions with distractors
