Enhanced stimulus contrast normalizes visual processing of rapidly presented letters in Alzheimer’s disease
Deficient perception and cognition in Alzheimer's disease (AD) has been attributed to slow information processing and attentional disturbance, but an additional explanation may be reduced signal strength. In 21 individuals with probable AD, 29 healthy older and 54 younger adults, we enhanced the contrast level of rapidly-flashed masked letters. The AD group reached identification criterion (80%...
متن کاملParallel Processing Letters Performance Evaluation of Jpvm
Received (received date) Revised (revised date) Communicated by (Name of Editor) ABSTRACT PVM for Java (JPVM) is a parallel programming environment that provides a set of Parallel Virtual Machine (PVM)-like class libraries developed using Java. JPVM inherits the attributes of Java, especially Java support of heterogeneous system. However, it also has the disadvantage of poor performance when co...
متن کاملProcessing of visually presented clock times.
The encoding and representation of visually presented clock times was investigated in three experiments utilizing a comparative judgment task. Experiment 1 explored the effects of comparing times presented in different formats (clock face, digit, or word), and Experiment 2 examined angular distance effects created by varying positions of the hands on clock faces. In Experiment 3, encoding and p...
متن کاملSpatiotemporal Form Integration: sequentially presented inducers can lead to representations of stationary and rigidly rotating objects.
Objects in the world often are occluded and in motion. The visible fragments of such objects are revealed at different times and locations in space. To form coherent representations of the surfaces of these objects, the visual system must integrate local form information over space and time. We introduce a new illusion in which a rigidly rotating square is perceived on the basis of sequentially...
متن کاملAn attentional blink for sequentially presented targets: evidence in favor of resource depletion accounts.
Several accounts of the attentional blink (AB) have postulated that this dual-target deficit occurs because of limited-capacity attentional resources being devoted to processing the first target at the expense of the second (resource depletion accounts; e.g., Chun & Potter, 1995). Recent accounts have challenged this model (e.g., Di Lollo, Kawahara, Ghorashi, & Enns, 2005; Olivers, van der Stig...
