Examines the perception of components of written and spoken codes of human communication from a broad perspective in an attempt to identify possible similarities. (GT)

We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

Memory for feature binding comprises a key ingredient in coherent object representations. Previous studies have been equivocal about human capacity for objects in the visual working memory. To evaluate memory for feature binding, a type identification paradigm was devised and used with a multiple-object permanence tracking task. Using objects…

Walking without vision results in veering, an inability to maintain a straight path that has important consequences for blind pedestrians. In this study, the authors addressed whether the source of veering in the absence of visual and auditory feedback is better attributed to errors in perceptual encoding or undetected motor error. Three…

A model is described to suggest how the visual system may keep track of perceived objects as their images move on the retina. (Author)

Examined effects of the self-concept, perception of spouse's evaluation, and spouse's actual evaluation on marital quality using interviews with 294 couples. The findings supported the prediction of a relationship between the three components of the reflected self-concept and marital quality and led to a reassessment of the…

Reality monitoring concerns the ability to distinguish knowledge that an individual has produced internally (through reasoning, imagination, etc.) from knowledge that was obtained through experience (or "externally"). A model of reality monitoring is proposed and discussed. (JKS)

The Feature Integration Theory of visual search proposed by A. M. Treisman and others (1980, 1986) is reviewed, and a modified Guided Search theory is presented in which the parallel stage guides the serial stage as it chooses display elements to process. A computer simulation illustrates the theory. (SLD)

Summarizes a theoretical framework and set of hypotheses aimed at accounting for consciousness in neurobiological terms. Discusses the functional neuroanatomy of nuclei in the brainstem reticular formation. Notes that the views presented are compatible with the idea that the reticular formation modulates the electrophysiological activity of the…

Functionalists about consciousness identify consciousness with a role; physicalists identify consciousness with an implementer of that role. The global workspace theory of consciousness fits the functionalist perspective, but the physicalist sees consciousness as a biological phenomenon that implements global accessibility. (Author)

Maintains that theorists are converging on a version of the global neuronal workspace model of consciousness, but that there are residual confusions to be dissolved. Asserts that global accessibility is not the "cause" of consciousness, it "is" consciousness. Argues that like fame, consciousness is not a momentary condition or…

The relative efficacy with which appearance of a new object orients visual attention was investigated. At issue is whether the visual system treats onset as being of particular importance or only 1 of a number of stimulus events equally likely to summon attention. Using the 1-shot change detection paradigm, the authors compared detectability of…

Two experiments with the inductive generalization procedure tested whether 16- and 20-month-old infants understand that animals and not vehicles follow a rational path to reach a goal. Infants were tested with four different events and the model exemplar was either an animal or ambiguous block. Results showed that infants at 20 months of age, but…

Time perception is important for many aspects of human behavior, and a large literature documents that adults represent intervals and that their ability to discriminate temporal intervals is ratio dependent. Here we replicate a recent study by vanMarle and Wynn (2006 ) that used the visual habituation paradigm and demonstrated that temporal…
