Merely thinking about a proposition can increase its subjective truth, even when it is initially denied. Propositions may trigger inferences that depend not on evidence for truth but only on the semantic match with relevant knowledge. In a series of experiments, participants were presented with questions implying positive or negative judgments of(More)
To assess dysphagia, the authors examined 12 patients with Kearns-Sayre syndrome (KSS) or chronic progressive external ophthalmoplegia (CPEO) due to mitochondrial DNA (mtDNA) deletion by videofluoroscopy and manometry. Cricopharyngeal achalasia was documented in nine of 12 patients (75%), whereas deglutitive coordination problems were found in one patient.(More)
We compared the sensitivity of single and triple dose Gd-DTPA magnetic resonance imaging (MRI) in detecting enhancing lesions in the spinal cord of 13 patients with multiple sclerosis (MS). We detected two enhancing lesions in two of 13 (15%) patients when the single dose of Gd-DTPA was used and 12 lesions in five of 13 (38%) patients when the triple dose(More)
A 49-year-old man reported several periods of acute paresis of different nerves after exposure to pressure. All palsies showed a good recovery over a period of days to months. The suspected diagnosis of a hereditary neuropathy with liability to pressure palsies was confirmed by the histology of a suralis nerve biopsy, which showed a distinct tomaculous(More)

What do memory data tell us about the role of contingency awareness in evaluative conditioning? (2011). Why do we like the iPhone? The role of evaluative conditioning in attitude formation.
In the present study we assessed the prevalence and nature of hearing loss in patients with chronic progressive external ophthalmoplegia (CPEO) or Kearns-Sayre syndrome (KSS) due to single large-scale mitochondrial DNA (mtDNA) deletion or mtDNA tRNA (Leu (UUR)) A3243G point mutation (A3243G PM). 14 patients with mtDNA deletion and three patients with A3243G(More)
An experimental study investigated the influence of priming on helping behavior. A scrambled sentence test was used to prime groups with the concepts of altruism or egoism. In a third group a neutral concept was activated. The results indicated that there is no difference in helping behavior between the altruism and the neutral group. However, in the egoism(More)
An experimental study investigated the joint influence of priming and situational cues on the perceived neediness of a target. A scrambled sentence test was used to prime two groups with the concepts of neediness and safety. In a third group a neutral concept was activated. A free description of the target and a subsequent adjective rating were applied as(More)
Automation of the control of complex systems has been achieved through the application of computers using such tools as closed-loop control, finite-state machines, etc. However, a number of tasks in the control of such processes must still be performed by human operators, resisting conventional automation efforts. These tasks usually involve unforeseen(More)
