    Sammanfattning : In recent years, the growing scientific interest in design has led to great advances in our knowledge of authentic design processes. However, as these findings go counter to the existing theories in both design research and cognitive science, they pose a serious challenge for both disciplines: there is a wide gap between what the existing theories predict and what designers actually do.

  4. 3. Noise improves cognitive performance in children with dysfunctional neurotransmission

    Detta är en avhandling från Stockholm : Psykologiska institutionen

    Författare :Göran Söderlund; Stockholms universitet.; [2007]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; noise; stochastic resonance; dopamine; episodic memory; model; brain arousal; SPT; cognitive performance; children; Psychology; psykologi;

    Sammanfattning : Research on children with Attention Deficit Hyperactivity Disorder (ADHD) has shown that they are extremely sensitive to distraction from external stimuli that lead to poor cognitive performance. This thesis shows that cognitive performance can be improved if this external stimulus is smooth and continuous (e.g. auditory white noise). LÄS MER
