Attention deficits • Deficits of the attention achievements are (apart from disturbances of the memory) the most frequent impairments after brain-damage or -illness (approx. 80%). • By their basis character disturbed attention achievements can entail restrictions in all areas of life. • Other cognitive and motor achievements depend much on the momentary attention achievement (e.g. fatigue). • An intact attention represents an important potential for the compensation of deficit achievements within other ranges.

Sub forms of attention The definition and organization of the sub forms of the attention achievements are not always uniform within the neuropsychology. Five attention components are essentially differentiated: 1. 2. 3. 4. 5.

Alertness, Vigilance (continuous attention), selective attention, visuo spatial attention, divided attention.

Diagnosis • The diagnosis of attention deficits in possible by the computerassisted procedures • According to the quality of the disturbance, attention disturbances must be trained highly specifically • Especially on disturbances of elementary aspects of attention (Alertness, Vigilanz), • if you use too complex, unsuitable therapy procedures, • a further degradation of the function may come (Prof. W. Sturm)

• Attention training is the only one training, which is possible without strategy learning (stimulation therapy)

Alertness Term of the Alertness (activatingness or awakeness) describes • on the one hand the general awakeness / activatingness of an individual (tonic component) as well as • on the other hand the ability to increase the activation level on a warning attraction (phasic component). • The Phasic Alertness can be defined thus as increase in attention on an event, taking place in near future, if this event is announced before. As measure usually serves the difference between the response time to simple visual stimuli with and without warning stimulus/tone.

• In RehaCom are 3 procedures for training of alertness (reaction training)

Reaction abilities (REA1) An endless number of stimulus-reactioncombinations can be provided.

Vigilance (continuous attention) • The ability, to uphold attention over longer, nonstop time periods, (Vigilance) • It is also subsumed by some authors under the concept of Alertness (Säring, 1987) • With tests, that determine the vigilance-performance, stimuli are presented normally over a longer times period. The relevant stimuli appear very rarely and in irregular sequence. Between the relevant stimuli numerous irrelevant stimuli appears (monotonous stimuli-situation). • If the relevant stimuli are coming more often, the term “duration attention” is used. For this type of the longer-time attention also the term "sustained attention" can be used.

Selective attention • Selective attention is marked through a filter-process, that promotes or suppresses the reception of information. • Under selective attention (also named as focused or pointed attention) we understand the focusing to a behavior relevant stimulus, if this stimulus is surrounded by non behavior relevant stumuli. • Typical diagnostic tasks are “multi reaction tasks”, where the patient has to react quick to relevant stimuli, while irrelevant stimuli has to fade off. • The concept of the selective attention is synonymously used with concentration-ability.

Divided attention • Divided attention means the focusing to more than one types of stimuli, while integrating this stimuli spatial or temporal into behavioral-irrelevant stimuli. • Patients with a disturbance of the divided attention frequently complain over difficulties to concentrate on several tasks simultaneously • They have difficulties with tasks, in which they have to observe simultaneously two stimuli-sources (e.g. an acoustic one and a visual one)

Disturbances of visuo-spatial attention • Frequent after brain damage (30-50% after left hemispheric damage, 50-70% after right hemispheric damage) • Subdivision in 4 main categories
