THE LATERALIZATION OF THE WORD FREQUENCY EFFECT
… The first was a small-n experiment varying visual angle of presentation, signal to noise ratios, visual field and word class (noun/verb) while using high frequency word and nonword items. The purpose of this experiment was to document the sensitivity of observers to material presented …

Perceived Size Modulates Cortical Processing of Objects
… there is also disagreement about whether the visual system is guided by holistic or analytical processes. Neuroimaging findings have revealed functional distinctions between low and higher-level visual processes across lateral occipital-temporal cortex (LOC), primary visual cortices (V1/V2) …

Perceptual Precedence in Picture Processing
… exist between the global and local levels in visual stimuli: In one type there is no predictive relationship between the global and local levels (i.e., their identities are independent), while the second type contains mutually predictable (dependent) global and local levels. Real-world viewing …

Optimised Mammogram Displays for Improved Breast Cancer Detection
… correlation, at a region size reflecting the visual angle subtended by the fovea, was much lower. Thus, decorrelation by the visual system was ineffective and performance for the detection of a blob in the paired images was also ineffective. This thesis suggests that, whilst animated displays …

PREDICTING THE USABILITY OF ALPHANUMERIC DISPLAYS
… of items on the display follows a predictable visual scheme. Objective ways of measuring these display characteristics have been developed and implemented in a computer program. In Experiment 1, 520 computer-generated displays that varied on these display measures were studied. Search times to …

The Role of Specific Attentional Influences in Anxiety and Perception
… assess the rela tionships 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 …

Detection of statistical differences between visual textures as a function of mean dot density
… of locally defined element density in visual textural stimuli was investigated. Ten female Ss participated in the experimental study for a total of two half-hour sessions each. The stimuli consisted of six replications of 40 visual displays. Four mean density (M.d.) conditions were …

Performance Assessment Methodology: Task Dependent Evaluation of Display Systems
… evaluating display image quality based on the visual events that occur in a task. The PAM approach identifies the visual events, decisions, and actions for a display system. To support PAM, a theoretical model, the Model of Visual Events (MOVE), is proposed for describing the relationship …

Aspects of hens’ visual behaviour
… conducted to examine different aspects of hens’ visual behaviour, and to assess whether hens respond to slide images in the same way as they respond to real conspecifics that those slides depict. Experiment 1 was a replication of a study by Candland (1969). Six domestic hens were trained to make …

Turning up the variable noise: the quiet eye, functional variability and advancements in perceptual cognitive expertise
… that lasts over 100ms, remaining within 3* of visual angle (Vickers, 2016). In the field of Goalkeeping (GK) the QE has been found to be one of the key mechanisms in understanding skilled performance (Piras and Vickers, 2011). It is widely accepted that expert performance is generally contrived …

Sensory Ecology of Foraging in Bumblebees
… I have examined size-related effects on the visual and olfactory system of Bombus terrestris. Chapter two deals with the effect of scaling on eye architecture and spatial resolving power of workers. Foraging efficiency in bees is strongly affected by proficiency of detecting flowers. Both …
