Preventing distraction by probabilistic cueing.
Involuntary attention switches triggered by infrequent, unpredictably occurring sensory events (distraction) can be prevented when participants are made aware of the forthcoming distractor. Previous studies exploring this phenomenon presented visual cues before each stimulus in an auditory oddball sequence. In one condition, cues were completely reliable in predicting the forthcoming distractor...
متن کاملSadness increases distraction by auditory deviant stimuli.
Research shows that attention is ineluctably captured away from a focal visual task by rare and unexpected changes (deviants) in an otherwise repeated stream of task-irrelevant auditory distractors (standards). The fundamental cognitive mechanisms underlying this effect have been the object of an increasing number of studies but their sensitivity to mood and emotions remains relatively unexplor...
متن کاملDistraction lengthening by callotasis in the hand.
The clinical results of 26 digits (18 patients) lengthened by distraction callotasis were evaluated and the factors which influenced healing were analysed. There were 14 men and four women, with a mean age of 39 years. All digits had suffered traumatic amputation. There were eight thumbs and 18 fingers. The level of the site of the osteotomy was at the proximal metaphysis in ten, the middle dia...
متن کاملModulation of competing memory systems by distraction.
Different forms of learning and memory depend on functionally and anatomically separable neural circuits [Squire, L. R. (1992) Psychol. Rev. 99, 195-231]. Declarative memory relies on a medial temporal lobe system, whereas habit learning relies on the striatum [Cohen, N. J. & Eichenbaum, H. (1993) Memory, Amnesia, and the Hippocampal System (MIT Press, Cambridge, MA)]. How these systems are eng...
متن کاملDistraction Osteogenesis
Distraction osteogenesis is increasingly used for bone lengthening of facial skeleton. Distractors may be intraoral and extraoral. The authors present development of distractors and their use for treatment of facial bones. Procedure may be used for treatment of malformations, syndroms, posttraumatic bone defects and deformities. The advantage of a distractor are a simple and fast procedure, sho...
