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 ... -
Electrophysiological correlates of flicker-induced color hallucinations
(Elsevier, 2009-03)In a recent study, Becker and Elliott [Becker, C., & Elliott, M. A. (2006). Flicker induced color and form: Interdependencies and relation to stimulation frequency and phase. Consciousness & Cognition, 15(1), 175-196] ... -
Electrophysiological correlates of flicker-induced form hallucinations
(The International Society for Psychophysics, 2010-10)Form hallucinations can be reliably induced using temporally modulated light within a specific frequency range (15-30Hz). The neural substrates of such states have yet to be established with certainty. Brain activity of 5 ... -
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 ... -
Emotional eating: feeding and fearing feelings - what psychologists need to know
(The Psychological Society of Ireland, 2017-06)This article reviews the psychological theories of emotional eating and introduces to a little known model, Affect Phobia, which combines both learning and psychodynamic theory -
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 ... -
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 ... -
Evidence for impaired integration-segmentation processes and slowed synchrony coding in dyslexics
(Pabst Science Publishers, 2001)Using a primed figure-detection task we were able to reveal the existence of two distinct groups of dyslexics. One group is characterized by a significant impairment of visual integration-segmentation processes, resulting ... -
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 ... -
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 ... -
Extended visual simultaneity thresholds in patients with schizophrenia
(Oxford University Press, 2009-07)Clinical observations suggest that the experience of time phenomenology is disturbed in schizophrenia, possibly originating disorders in dynamic cognitive functions such as language or motor planning. We examined the ... -
Fechner's colors are induced by flickering monochromatic light
(Pabst Science Publishers, 2001)Fechner described the phenomenon of inducing illusory colors by means of rotating blackand- white disks. The induced spectral illusions were later termed "Fechner's colors". Similar color perceptions can be induced by ... -
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 ... -
General practitioner views about discussing sexual issues with patients with coronary heart disease: a national survey in Ireland
(2010)Background: Sexual problems are common among people with coronary heart disease and can adversely affect patients' quality of life. GPs are ideally placed to deal with these problems. Research suggests that GPs are reluctant ... -
Improving medication management in multimorbidity: development of the MultimorbiditY COllaborative Medication Review And DEcision Making (MY COMRADE) intervention using the Behaviour Change Wheel
(2015-09-24)Background: Multimorbidity, the presence of two or more chronic conditions, affects over 60 % of patients in primary care. Due to its association with polypharmacy, the development of interventions to optimise medication ... -
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 ... -
Is a therapist's attachment style predictive of stress and burnout in a sample of Irish therapists?
(IACP Irish Association for Counselling and Psychotherapy, 2017)The current study investigated whether attachment style, as measured by levels of attachment anxiety and avoidance, in a sample of (N = 137) therapists predicted stress and burnout. A series of hierarchical multiple ... -
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 ... -
Low time resolution in schizophrenia: Lengthened windows of simultaneity for visual, auditory and bimodal stimuli
(Elsevier, 2007-12)The guarantee of perceptual coherence for events through everyday life situations depends upon the capacity to correctly integrate series of multi-sensory experiences. Patients with schizophrenia have been shown to reveal ...
