Change blindness in profoundly deaf individuals and cochlear implant recipients.

We used a change blindness paradigm to examine visual abilities in the profoundly deaf when exogenous capture of attention is prevented and only endogenous attention shifts are possible. Nineteen profoundly deaf participants, 22 cochlear implant recipients and 18 hearing controls were asked to detect a change occurring between two consecutive visual scenes separated by a blank. Changes occurred on half of the trials, either at central or peripheral locations, and the task was performed under focused attention (at the centre or at the periphery) or under distributed attention.

Semantic descriptors of pain.

Eighty-five patients suffering from advanced cancer pain were asked to attribute a 'definite value' to 5 key words describing pain by rating them on a visual analogue scale (VAS). The score which the patient attributed to each key word was then correlated with 9 variables obtained through patient monitoring files (sex, age, educational background, financial situation, integrated pain score, number of concomitant symptoms, hours of sleep and standing, performance status). The visual analogue rating of pain description was not related to the variables examined.
