Zebrafish Retinal Development And The Effects Of Abnormal Light Rearing Conditions, Shannon Saszik Aug 1998

Zebrafish Retinal Development And The Effects Of Abnormal Light Rearing Conditions, Shannon Saszik

Masters Theses & Specialist Projects

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). Physiologically, the adult zebrafish appears to have a complex visual system with color opponent mechanisms. Anatomical results suggest that the zebrafish may be a good model of retinal development as well. The zebrafish retina develops in a sequential manner and is immature at hatch. Bilotta et al. (1996) also found that the retina was …


Iconic Memory And Aging: Effects Of Stimulus Duration, Stimulus Contrast, And Inter-Stimulus Interval, Andrew Lajoie May 1998

Iconic Memory And Aging: Effects Of Stimulus Duration, Stimulus Contrast, And Inter-Stimulus Interval, Andrew Lajoie

Masters Theses & Specialist Projects

Previous studies have shown that old adults perform more poorly on the classic Sperling partial report task than do young adults. In this study, the researcher examined whether age differences in performance 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 of 30 ms. Stimuli were presented at two levels of contrast (98 and 44 percent) and the …

Cognitive And Psychophysiological Investigation Of Chronic Pain, Amy D. Clegg Mar 1998

Cognitive And Psychophysiological Investigation Of Chronic Pain, Amy D. Clegg

Loma Linda University Electronic Theses, Dissertations & Projects

Using Bower’s (1981) associative network model of mood and memory, and Klinger’s theory of current concerns, it was hypothesized that the experience of chronic pain may be functionally similar to a mood state and that the chronicity of the condition may maintain it as a current concern. Specifically, it was hypothesized that chronic pain patients would not show any differences in reaction time and accuracy when making lexical decisions about pain-related, neutral, and nonwords. However, it was anticipated that chronic pain patients would show differences in physiological responding (particularly, increased skin conductance responses) when compared to controls. Results confirmed that …


Images Of Mary: Effects Of Style And Content On Reactions To Marian Art, Donald J. Polzella, Johann G. Roten S.M., Christopher W. Parker Jan 1998

Images Of Mary: Effects Of Style And Content On Reactions To Marian Art, Donald J. Polzella, Johann G. Roten S.M., Christopher W. Parker

Psychology Faculty Publications

105 college students rated digitized facsimiles of works of art depicting the Virgin Mary, which varied in style (Pre-Renaissance versus Renaissance and Post-Renaissance) and content (depictions of events versus devotional images). Viewer reactions were affected strongly by style, content, and their interaction. For example, the newer style was perceived to have greater power and clarity than the older style, and this effect was greater for event depictions than for devotional images. Other findings included differences in reactions between men and women.


The Effect Of Pre-Interview Training And Warnings On Children's Eyewitness Testimonies, Julie A. Jost Jan 1998

The Effect Of Pre-Interview Training And Warnings On Children's Eyewitness Testimonies, Julie A. Jost

Theses : Honours

The present study examined two important issues regarding children's eyewitness testimonies -compliance which is the tendency to agree with misleading questions and the misinformation effect whereby participants incorporate misleading postevent information into their memory recall of the original event. Eighty six primary school children (6-8 years) watched a video, listened to a misleading narrative and were then interviewed individually. To reduce compliance half the children received a pre-interview training package composed of instructions and practice questions with 'neither' and 'don't know' response options. To reduce the misinformation effect children were given a warning that they may have heard some misleading …


Sequential Testing Effects Re-Visited : Is The Effect Of Test Presentation Contingent Upon Slide Linearity?, John D. Jones Jan 1998

Sequential Testing Effects Re-Visited : Is The Effect Of Test Presentation Contingent Upon Slide Linearity?, John D. Jones

Theses : Honours

Evidence regarding the potential mediating effects sequential test presentation has upon eyewitness suggestibility is divided. Bekerian and Bowers' (1983) research suggested that sequential test presentation reduced misinformation effects, whilst McCloskey and Zaragoza's (1985) results failed to indicate any effect of this presentation method. A possible reason for these conflicting results is that the respective research groups have used different sets of slides. Bekerian and Bowers' (1983) slides appeared to contain more thematic content (i.e., linear content), which in turn increased participants' resistance to misleading postevent information. Conversely, McCloskey and Zaragoza's (1985) slides appeared to lack this feature (i.e., they are …


A Voice For Our Future: High-Risk Adolescents' Perceptions And Experiences About Help And Healing Interventions, Cameron Dale Norman Jan 1998

A Voice For Our Future: High-Risk Adolescents' Perceptions And Experiences About Help And Healing Interventions, Cameron Dale Norman

Theses and Dissertations (Comprehensive)

This critical ethnography examines the perceptions of adolescents at-risk with respect to their experiences of help, both formal and informal. Ten (10) adolescents who had been involved with the Bridges psychoeducational program, an interagency partnership intervention for high-risk youth in the Waterloo region, were interviewed about their experience with the programs and people who attempt to support them. Placing great importance on using the adolescent’s words to speak to their own needs and experiences, this study's main findings suggest that adolescents are not given voice by many helpers; most help agents fail to truly help these adolescents in a meaningful …
