Adult age differences in a visual search, luminance contrast discrimination task
(2003)This thesis examined the ability of younger and older adults to use peripherally presented word cues in a luminance contrast discrimination task. Observers were ten older adults (aged 55 to 69) and ten younger adults ... -
Adult Attention-Deficit Hyperactivity Disorder (ADHD) and the isolation of low and high end component operations in temporal processing and time perception
(2009)Evidence has shown that Attention-Deficit Hyperactivity Disorder (ADHD) is associated with deficits in temporal processing and time perception (Toplak & Tannock, 2004). Current literature, however, focuses on time perception ... -
Aesthetic ratings of northern forest scenes : the effects of spatiochromatic stimulus attributes in silvicultural landscape images
(1996)The Environmental Impact Assessment Act, through the use of The Social Impact Assessment (SIA) established public participation in environmental decision-making. The concern for landscape aesthetics has been one among ... -
Assessment of magno-, parvo-, and koniocellular visual streams in migraine / by James Brazeau.
(2008)Although visual abnormalities have been noted in migraine, no studies have specifically sought to assess all three visual processing streams. We are the first to psychophysically assess visual functionality of the magnocellular ... -
Bimodal discrimination tasks involving different hierarchical processing levels reveal a late stage interaction between multisensory integration and attention
(2014-12-19)Multisensory integration and attention have been studied independently and a vast amount of literature exists for both phenomena. Researchers have recently raised questions, however, as to how these two processes interact. ... -
Colour appearance of perceived illuminants and surfaces
(1994)The colour appearance of a patch of light is only partly determined by the light itself. A patch's perceived colour can also be influenced by cognitive processes. Cognitive effects on colour appearance were examined ... -
The effect of cycling female estradiol levels on retinal-based smooth pursuit eye movements (SPEM) and post-target offset persistence
(2015-06-15)Estradiol has primarily been associated with the female reproductive system; however, estradiol receptors have been located in the retinas of male and female humans, as well as throughout the central nervous system (CNS) ... -
Impact of depression and antidepressant pharmacotherapy on early stage visual functioning in the magno-, parvo-, and koniocellular pathways / by Joy J. Harrison.
(2010)Examines the fundamental processes of photopic visual functioning associated with the use of selective serotonin reuptake inhibitors (SSRIs), the most commonly prescribed type of antidepressant medication. Measures ... -
Individual differences in timing sensitivity : implications for interval timing models / Jeannette H. Prenger. --
(2005)Time discrimination performances were examined using either a steadily presented or a heterochromatic luminance flickering visual standard-time-interval stimulus to address certain questions : 1. Are individual differences ... -
Seeing without rods or cones: contributions of intrinsically-photosensitive retinal ganglion cells to the image-forming visual system
(2014-01-22)It was long thought that rods and cones were the only components of the mammalian retina capable of conveying light information to the brain. Recently, a novel class of transduction-capable retinal ganglion cells containing ... -
Spatial and attentional influences on nonverbal magnitude discrimination in depressed and non-depressed individuals / by Stewart A. Madon.
(2008)Numbers have been called the universal language. Yet the psychophysical properties of numerosity remain elusive, particularly as they relate to clinical disorders such as depression. It is known that the estimation and ... -
Visuo-perceptual task performance across the menstrual cycle in women with and without premenstrual symptoms: potential influences of estradiol and estradiol sensitivity on retinogeniculostriate, extrastriate, and elementary retinal-based smooth pursuit pathways
(2012-11-10)The present study examined whether women with premenstrual symptoms (PMS) exhibit a different pattern of performance on psychophysical tasks across the menstrual cycle in comparison to control women. Research has shown ...
