A case of 'pure' word blindness.
The concept of 'pure' word blindness is still a matter of controversy. Some authors maintain that it is a selective asymbolia (Holmes, 1950; Symonds, 1953; Brain, 1955) while others (Critchley, 1953) consider it to be an aphasic disorder. Beringer and Stein (1930) attribute its mechanism to some pathological functional lability of the visual system. Martin (1954) assumes that it is due to visua...
متن کاملOBSERVATION Blinded by Irrelevance: Pure Irrelevance Induced “Blindness”
To what degree does our representation of the immediate world depend solely on its relevance to what we are currently doing? We examined whether relevance per se can cause “blindness,” even when there is no resource limitation. In a novel paradigm, people looked at a colored circle surrounded by a differently colored ring—the task relevance of which was previously manipulated—and were subsequen...
متن کاملBlindness and Verification of Quantum Computation with One Pure Qubit
While building a universal quantum computer remains challenging, devices of restricted power such as the so-called one pure qubit model have attracted considerable attention. An important step in the construction of these limited quantum computational devices is the understanding of whether the verification of the computation within these models could be also performed in the restricted scheme....
متن کاملPure somaesthetic alexia: somaesthetic-verbal disconnection for letters.
We studied a patient who manifested a bilateral reading disorder through the somaesthetic modality, without deficit of elementary tactile sensation or tactile object naming, due to a left parietal infarct. Detailed investigation established the following points. (i) The patient showed normal function on elementary somaesthetic examination, normal function on high level tactile perception, excep...
متن کاملBlindness in Randomized Controlled Trials
In combination with randomization, blinding or masking is an important factor in randomized controlled trials (RCTs), particularly in trials that assess therapeutic effects. Here an attempt is made to explain blindness and why it is important. In clinical trials, blinding is defined as the condition imposed on a study in which study participants, health care providers and assessors collecting o...
