Material matters : color, pattern, cognition, and perception in quilts from the Winedale Collection
… nearly fifty years as masterpieces of unschooled and unintentional modernism, and their mostly female makers cast as implicitly innocent and ignorant. Myth and convention hold that patchwork quilts materialized from scraps of cloth and an unconscious or automatic kind of labor. In fact, quilts …

A study of the detrimental impact of rape mythologies and victim stereotypes in the application of character evidence in jury trials in England and Wales
… aims to analyse the presence of rape mythologies and victim stereotypes brought about by the presentation of certain evidence in rape trials and to utilise the psychological research behind cognition and perception to help explain why it is important that the law re-examine how it handles these …

Quad general tree drawing algorithm and general trees characterization: towards an environment for the experimental study on general tree drawing algorithms
… of abstract data to reinforce human cognition and perception; thus enabling the viewer to gain knowledge about the internal structure of the data and causal relationships in it. The visualization of information hierarchies is concerned with the presentation of abstract hierarchical …

Panoptic
Imagine traveling to a destination and, once you are there, hearing only car horns or seeing only a green sky. This project is an augmented reality experience in which you see and hear your current city while you are in another location through an immersive helmet. The multimodal experience …

Activation of the corticolimbic brain by visual food cues; Effect of menstrual cycle phase and mood
… of food intake may be overridden by cortical and limbic brain regions that process reward and the hedonic aspect of food, affecting the ability to discriminate between homeostatic and hedonic feeding. Women, in particular may be affected since cognition and perception of reward change during …

The Role of Specific Attentional Influences in Anxiety and Perception
… between trait anxiety, visual attention and perceptual closure. A neuropsychological model proposed by Pribram and McGuinness (1975) and elaborated by Tucker and Williamson (in press) is used as a basis for the con cepts of attention, arousal, and cognition used in this paper. Specific, …

Cognition in healthy aging and Parkinson's disease : structural and functional integrity of neural circuits
This dissertation documents how healthy aging and Parkinson's disease (PD) affect brain anatomy and physiology and how these neural changes relate to measures of cognition and perception. While healthy aging and PD are both accompanied by a wide-range of cognitive impairments, the neural …

Aging and the Truth Effect in Validity Judgment
… influence of increasing age on the truth effect and recognition of repeated statements. Younger and older adults were asked to rate a series of statements for validity. Two weeks later, the subjects rated a similar list containing some new statements along with statements repeated from the first …

An Investigation of Peripheral Localization Errors in Older Adults
… gap between the offset of a fixation point and the onset of a peripheral stimulus helps to facilitate the disengagement of focal attention. This explanation of peripheral localization difficulties in older adults posited that some older adults have a slowing in the ability to disengage …

The Effects of Practice on Stroop Inhibition: A Process Dissociation Approach
… were performed to investigate the effects of age and practice on Stroop inhibition. The first experiment examined the influence of age on the ability to ignore the meaning of words on Stroop items. Fifteen younger and 15 older adults were asked to name the color of congruent, incongruent, and …

Aging and Attentional Control in the Stroop Priming Task
… from irrelevant information. Sixty young and 60 older adults were asked to name the ink color of a non-black neutral word, which was presented adjacent to a color word or a neutral word (Lowe & Mitterer, 1982). Twelve young and 12 older adults were assigned to 1 of 5 list compositions. The …

Aging and Stereoscopic Shape Perception
Past research on stereoscopic depth perception among the elderly has led to inconsistent findings. Some research on stereopsis and aging has found that younger and older adults are essentially the same in terms of their stereoscopic ability, while other research has found evidence of large …

The Effect of Cognitive Load on Illusory Correlation
… secondary task while stimuli were presented and the level of illusory correlation was examined after low, medium, and high levels of cognitive load. The findings failed to provide support for either the distinctiveness-based or the differentiated meaning view. However, there was some …

The Effect of Age-Related Stereotypes on Memory Self-Efficacy and Memory Task-Performance of Older Adults
… stereotypes of age-related memory decline and memory self-efficacy beliefs. It was also hypothesized that this relationship affects performance on measures of memory performance. A measure of age stereotype vulnerability was assessed along with two measures of memory self-efficacy, four …

Exploration of the Relationship Between Moral Judgment Development and Crystallized Intelligence

The Perception and Recognition of 3-D Shape from Shadows Cast onto Curved Surfaces
… shadow or silhouette boundary contour for the perception of 3-D object shape has been investigated for a long time. Some researchers have focused on the informativeness of static shadows (Attneave, 1954; Koenderink, 1984; Richards, Koenderink, & Hoffman, 1987; Norman, Phillips, & Ross, 2001; …

Zebrafish Retinal Development and the Effects of Abnormal Light Rearing Conditions
<p>Anatomical and physiological studies have shown that the zebrafish is a useful model of vertebrate visual function. Anatomy has shown that the zebrafish possess the traditional three cone types (S-, M-, and L- cones), and a fourth cone type that is sensitive to ultraviolet light (U-cones). …

Iconic Memory and Aging: Effects of Stimulus Duration, Stimulus Contrast, and Inter-Stimulus Interval
… could be accounted for by changes in visual and perceptual ability. Eighteen old adults (M = 70 years) and 18 young adults (M = 22 years) were administered whole and partial report trials with stimulus durations of 150 ms; a second group of 18 young adults was tested with stimulus durations …

Memory for Non-Focal Words
… was used to simultaneously present a focal word and an incidental non-focal word. The participants' task was to process the focal word in one of two conditions: naming aloud or a conceptual decision (concrete or abstract). The focal and non-focal words were either semantically related or not. …
