Synchronous information presented in 40-Hz flicker enhances visual feature binding
(Blackwell, 1998-01)Recent neurophysiological studies have encouraged speculation that the synchronization of spatially distributed neural assemblies (at around 40 Hz in the neocortex) is responsible for the binding of discrete stimulus ... -
Can we explain cross-modal representation with neural algorithms alone?: Commentary on Paillard
(North-Holland, 1999)Recent research in both psychophysics and electrophysiology has revealed a number of examples in which behaviour is guided by (i.e. Spence & Driver, 1996), and brain activity has been argued to correlate with, the formation ... -
The Politics of Housing; Social Change and Collective Action in Derry in the 1960s

Evidence for 40-Hz oscillatory short-term visual memory revealed by human reaction-time measurements
(American Psychological Association, 2000-05)Four experiments show that presentation of a synchronous premask frame within a 40-Hz, flickering premask matrix primes subsequent detection of a Kanizsa-type square by generation of a 40-Hz prime. Reaction time (RT) priming ... -
Enhanced GABA-A inhibition enhances synchrony coding in human perception
(Lippincott Williams & Wilkins, 2000-10-20)The benzodiazepine, lorazepam enhances the efficiency of local, inhibitory GABAA synapses in the cortex, which stabilize postsynaptic, excitatory activity by synchronizing their own discharges at around 40 Hz. Treatment ... -
The loci of oscillatory visual-object priming: a combined electroencephalographic and reaction-time study
(Elsevier, 2000-12)The detection of reaction-times (RTs) to a target Kanizsa-type square (an illusory square defined by the collinear arrangement of 90° corner junctions) within a matrix of distractor junctions are expedited when the target ... -
Dynamics of perceptual grouping: similarities between the organization of visual and auditory groups
(Taylor & Francis, 2001-06)In vision, the Gestalt principles of perceptual organization are generally well understood and remain a subject of detailed analysis. However, the possibility for a unified theory of grouping across visual and auditory ... -
Effects of stimulus synchrony on mechanisms of perceptual organization
(Taylor & Francis, 2001-06-05)When neurons adopt a synchronized, oscillatory response to stimulus Gestalten, the phase of those oscillations almost always varies relative to stimulus activity. This has been taken to indicate that form-coding mechanisms ... -
Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003)In this commentary, the formation of ¿pre-iconic¿ visual-prime persistence is described in the context of prime-specific, independent-component activation at prefrontal and posterior EEG-recording sites. Although this ... -
Divided attention in older but not younger adults is impaired by anxiety
(Taylor and Francis, 2003)It has been hypothesized that the disruptive effects of negative emotional states, such as anxiety and depression, may contribute to poorer performance in older age. Some studies have reported that higher levels of anxiety ... -
Prefrontal cortex and the generation of oscillatory visual persistence
(Cambridge University Press, 2003-12-01)In this commentary, the formation of "pre-iconic" visual-prime persistence is described in the context of prime-specific, independent-component activation at prefrontal and posterior EEG-recording sites. Although this ... -
Synchronization and stimulus timing: Implications for temporal models of visual information processing.
(Lawrence Erlbaum and Associates / Psychology Press (Taylor & Francis), 2004)In the visual system, objects and object groupings may be initially coded in terms of physically separable attributes or features, representing differential spatial frequencies, orientations, colors, directions of motion, ... -
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 ... -
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 ...
