Eye movements and the perceptual span in older and younger readers.
30 Aug 2009 
The size of the perceptual span (or the span of effective vision) in older readers was examined with the moving window paradigm (G. W. McConkie & K. Rayner, 1975). Two experiments demonstrated that older readers have a smaller and more symmetric ...

Visual field motion effects on the production of manual forces and displacements.
30 Aug 2009 BACKGROUND: We have previously shown that subjects produce exaggerated arm forces when exposed to three times the normal gravitational acceleration (+3 Gz), and that this deficit is not related to direct mechanical effects, faulty proprioception, or ...

On the control of single-prime negative priming: the effects of practice and time course.
30 Aug 2009 Single-prime negative priming refers to the phenomenon wherein repetition of a prime as the probe target results in delayed response. Sometimes this effect has been found to be contingent on participants' unawareness of the primes, and sometimes it ...

27 Aug 2009 The present study investigated the influence of attention on the human sensitivity to valence differences in emotionally negative stimuli. Event-related potentials were recorded for unattended highly negative (EN), moderately negative (MN) and ...

26 Aug 2009 AIM: To construct and validate a mini-battery to discriminate between Alzheimer's disease (AD) and mild cognitive impairment (MCI) in patients seen at a hospital memory clinic. METHODS: In a cohort of 310 subjects (137 with MCI and 173 with AD), the ...

Expectation (and attention) in visual cognition.
25 Aug 2009 Visual cognition is limited by computational capacity, because the brain can process only a fraction of the visual sensorium in detail, and by the inherent ambiguity of the information entering the visual system. Two mechanisms mitigate these ...

Neural generators of sustained activity differ for stimulus-encoding and delay maintenance.
25 Aug 2009 The ability to maintain information online beyond sensory stimulation is regarded as a key contribution of working memory to goal-directed behaviour. It is widely accepted that sustained neural activity is a key mechanism of stimulus maintenance, ...

25 Aug 2009 Psoriasis produces significant psychosocial disability; however, little is understood about the neurocognitive mechanisms that mediate the adverse consequences of the social stigma associated with visible skin lesions, such as disgusted facial ...

Persistence of neuropsychological testing deficits in mild cognitive impairment.
24 Aug 2009 BACKGROUND: The significant variability across studies of mild cognitive impairment (MCI) in rates of progression to Alzheimer's disease (AD) and reversion to normal cognition may be due to differences in specific neuropsychological tests and ...

Center-surround organization of face-space: evidence from contrast-based face-priming.
24 Aug 2009 'Face-space' is an abstract concept of the multidimensional representation of faces. Faces of similar appearance are closer in face-space than dissimilar faces; however, it is not clear how representations interact. Examining contrast thresholds for ...
