Relational frame theory and stimulus equivalence: Conceptual and procedural issues
(2004)The article begins with a brief outline of the phenomenon of stimulus equivalence and its relationship to human verbal behavior. Relational Frame Theory is then outlined as a behavior-analytic account of both stimulus ... -
The dynamics of operations in visual memory: A review and new evidence for oscillatory priming
(Hogrefe & Huber, 2004-10)Evidence from neurophysiological studies indicates that the synchronization of distributed neuronal assemblies in the gamma frequency range is responsible for the integration of discrete stimulus components into coherent ... -
Expectancy, not memory determines identical search rates in static and dynamic displays.
(International Society for Psychophysics, 2005)Search rates are often used as a measure of search efficiency. Horowitz & Wolfe employed this measure to compare static and dynamic visual search (Horowitz & Wolfe, 1998). Based on identical search rates, they argued that ... -
Temporal tolerance circumscribed
(Taylor & Francis, 2005-05)Chen's topological theory of perceptual organization includes the idea that equivalences in spatial organization and the organization of subjective experiences of time may be derived by means of common expression in terms ... -
Evidence for impaired visuo-perceptual organization in developmental dyslexics and its relation to temporal processes.
(Taylor & Francis, 2005-07)An analysis of normal and dyslexic readers' reaction-time (RT) performance in a standard visualdetection task (Experiment A) and in temporally primed visual detection (Experiment B) reveals a tendency for significantly ... -
Some facilitatory effects of lorazepam on dynamic visual binding
(Springer, 2006)Rationale: The benzodiazepine lorazepam enhances the potential for inhibitory (GABAA) synapses in the cortex to stabilize postsynaptic, excitatory activity by synchronizing discharge rates at frequencies of around 40 Hz. ... -
An investigation of cognitive dysmetria in developmental dyslexia
(Pion Ltd, 2006)An alternative to theories positing visual or phonological deficits, the 'cognitive dysmetria' hypothesis proposes the aetiology of dyslexia to take the form of a general functional coordination deficit or cognitive ... -
Consciousness of brain
(Psychological Society of Ireland, 2006)Evolved consciousness makes possible a rich variety of experience, transmissible from mind to mind via poetical and logical symbolism. Scientific experience involves mapping the energy of the system onto a correspondent ... -
Flicker-induced color and form: Interdependencies and relation to stimulation frequency and phase
(Elsevier, 2006-03)Our understanding of human visual perception generally rests on the assumption that conscious visual states represent the interaction of spatial structures in the environment and our nervous system. This assumption is ... -
Visual perception in a snapshot
(Springer, 2006-04-14)To study visual perception in its sub-second scale of time continues to be timely: we have more unsolved puzzles than bits of a firm undisputable knowledge about how our perceptions are created in a snapshot of time. ... -
Cultivating thought-full and creative thinkers: A comment on quality merging Costa with Claxton et al.
(Elsevier, 2006-05-15)The two keynote papers in the first issue of Thinking Skills and Creativity provide significant food for thought. Working to teach thinking skills and creativity is a real challenge. Many university professors shadow this ... -
Electrophysiological correlates of similarity-based interference during detection of visual forms
(MIT Press, 2006-06)Illusory figure completion demonstrates the ability of the visual system to integrate information across gaps. Mechanisms that underlie figural emergence support the interpolation of contours and the filling-in of form ... -
Grappling with gene-culture co-evolution
(The Irish Psychologist, 2006-06)Human beings strive to understand. Understanding helps us to survive, adapt, and flourish. A central theme in the history of philosophical and religious thought has been the call to "know thyself" and to "understand thy ... -
A moment to reflect upon perceptual synchrony
(MIT Press, 2006-10)How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons ... -
Against didacticism
(2006-10)Quality thinking and quality teaching are desirable but difficult to achieve. Although lectures are necessary to teach information, one cannot rely on them to promote critical and constructive thinking skills. Nevertheless, ... -
Defining perceptual synchrony
(Kijima Printing Co., 2007)How does neuronal activity bring about the interpretation of visual space in terms of objects or complex perceptual events? If they group, simple visual features can bring about the integration of spikes from neurons ... -
The effects of subthreshold synchrony on the perception of simultaneity
(Springer, 2007)We aimed to examine the effects of subthreshold synchrony and asynchrony on the perception of simultaneity. We rendered simultaneous or asynchronous luminance changes below detection thresholds by embedding them in a ... -
The effects of subthreshold synchrony on the perception of simultaneity.
(Springer, 2007)We aimed to examine the effects of subthreshold synchrony and asynchrony on the perception of simultaneity. We rendered simultaneous or asynchronous luminance changes below detection thresholds by embedding them in a ... -
Closure of salient regions determines search for a collinear target configuration
(Psychonomic Society, 2007-01)Grouping operations offer an effective mechanism by which to structure complex visual scenes. Among the various principles that support element integration, closure may be regarded as a main factor in shape extraction. In ... -
Oscillatory priming and form complexity
(Psychonomic Society, 2007-02)Detection of a target grouping is expedited when the target display is preceded by presentation of an oscillating premask that includes priming elements presented intraphasically and below detection threshold at the display ...
