Curvature Contingent Color Aftereffects.
… paper will deal with curvature contingent color aftereffects (AE), a development from the pattern contingent aftereffects reported by Celeste McCollough (1965). After McCollough’s findings are described briefly, the relative importance of spatial frequency characteristics in inducing AE will be …

SIMPLE AND CONTINGENT CHROMATIC AFTEREFFECTS IN PIGEONS
… pigeons acquire simple and contingent chromatic aftereffects, four White Carneaux pigeons were trained to discriminate between colored and achromatic slides: Right and left key-pecks were reinforced following exposure to colored and achromatic slides, respectively. The chromatic set included …

Selectivity of Facial Aftereffects for Changes in Gender and Expression
… face perception is to examine face adaptation aftereffects. For instance, when an observer views a distorted face (e.g. contracted) for a prolonged period of time, a normal face will appear to be distorted in the opposite direction (e.g. expanded). Several studies have utilized these adaptation …

Induced Near-Death Experiences in Healthy Volunteers: Phenomenology and Aftereffects
… with hypnosis and produce some of its typical aftereffects. Using a quasi-experimental mix-method with non-clinical participants in two rounds of data collection, Study I and II, conducted with convenience and purposive samples, respectively, it was possible to conclude that hypnosis was …

Static and dynamic motion aftereffects of first- and second-order motion in central and peripheral fields of vision
After prolonged adaptation to a moving pattern, a subsequently presented static or dynamic test pattern will appear to drift in the opposite direction. This illusory drift is referred to as the motion aftereffect (MAE). It is well accepted that a MAE is not elicited after adaptation to second-order …

The development of norm-based coding and category-specific face prototypes : an examination of 5- and 8-year-olds' face space
… and more attractive (simple attractiveness aftereffects). Recent studies have shown that adults possess category-specific face prototypes (e.g., based on race, sex). After viewing faces from two categories (e.g., Caucasian/Chinese) that are distorted in opposite directions, adults' …

The Role of Spatial Structure in Human Duration Processing
… stimulus size. Adaptation experiments generated aftereffects of perceived duration within stimuli whose durations were defined solely by retinal disparity, providing the first demonstration of duration selectivity within exclusively cortical duration encoding mechanisms. The selectivity of these …

Investigating neuromodulation with theta burst stimulation to primary visual cortex and subsequent effects on resting state networks: A multi-echo fMRI study
… TBS (iTBS) has been shown to yield excitatory aftereffects, whereas continuous TBS (cTBS) may lead to inhibitory aftereffects, both lasting from minutes to hours. The majority of TBS research has targeted motor and non-motor frontal areas of the brain, and to date very few studies have examined …

Wellbeing Impacts and Clinical Implications of Near-Death Experiences
This thesis aims to identify challenging aftereffects of near-death experiences (NDEs), to explore how these are lived by near-death experiences (NDErs), and to study the impacts of these challenging aftereffects on psychological wellbeing. This thesis also aims to identify what aids integration of …

Adaptation to Interocular Differences in Blur
… Adaptation to both types of blur produced strong aftereffects that showed strong transfer across the eyes. Greater transfer was found for the isotropic blur than for the oriented blur, both in a monocular adaptation task and in a contingent adaptation task in which the two eyes were simultaneously …

Response patterning in goldfish: single alternation in a Pavlovian aversive paradigm
… it was determined that neither a sensory aftereffects trace hypothesis nor a memorial representation hypothesis could exclusively account for the present results, the observation of response facilitatory aftereffects of shock presentations within groups receiving random reinforcement …

Exploring the phenomenon of recovery for chemically dependent women survivors of childhood sexual abuse
… where the process is compounded by the aftereffects of childhood sexual abuse trauma. All eight women reported a desire to maintain a drug and alcohol free lifestyle but repeatedly found themselves abusing substances until they understood the connection between their addiction patterns …

A global framework for scene gist
… category. Finally, in Chapter 3, I explore aftereffects to adaptation to global properties, showing that repeated exposure to many global properties produces robust high-level aftereffects, thus providing evidence for the neural coding of these properties. Altogether, these results provide …

The electrophysiological correlates of processing expression intensities along emotion trajectories
… intensity observed in behavioural adaptation/aftereffects experiments. We replicated EPN intensity effects for adaptor stimuli, but not the test stimuli. Furthermore, there were no systematic behavioural effects to assess whether the EPN might reflect perceptual shifts. Further refinement of …

Speculating after the Interregnum: Utopia and Apocalypse in Cape Town

Temporal and spatial contextual modulation of walking direction in biological motion
… direction results in repulsive perceptual aftereffects. The observed tuning profiles are well explained by a population coding model, in which perceived walking direction is coded in terms of the relative activity across a bank of sensory channels with peak tuning distributed across the …

"I'd Rather Be Forgotten Than Dishonored": An Oral and Life History Project with a Vietnam Veteran
