Verbal Learning And Memory In Adults With Mild, Moderate And Severe Closed Head Injury, Paula J. Bergloff

Theses and Dissertations

One of the most prevalent of cognitive dysfunctions associated with closed head injury is impaired_memory function. The current study examined qualitative and quantitative aspects of learning and memory to define the effects of mild head injury in comparison to moderate and severe head injury and a sample of normal controls.

Forty five survivors of severe (n=15), moderate (n=15) and mild (n=15) closed head injury were compared with age and education matched controls (n=15) on the California Verbal Learning Test (CVLT) and the Wechsler Memory Scale (WMS). On CVLT learning trials, head injured groups recalled less than controls, with the severely …

The Interactive Effects Of Caffeine And Phase Of Menstrual Cycle On The Recall Of Prose Passages, Jacqueline Marie Mcpherson

Theses and Dissertations

Previous research has yielded inconsistent results regarding the effects of caffeine on memory. Such inconsistency is likely to a large extent a function of the complex interaction effects of caffeine and other variables such as estrogen. The purpose of the present study was to discern possible variation in the effects of caffeine on the recall of prose for females tested during days 1-5 or 9-13 of their menstrual cycle. One hundred and seven subjects received either O mg/kg, 2 mg/kg, or 4 mg/kg of caffeine. Following an absorption period, subjects read six passages from a computer terminal and immediately afterwards, …

Noun Classification Or Spatial Categorization: Damana Orientation Verbs, Larry P. Williams

Theses and Dissertations

This thesis argues against a nominal classification analysis of orientation verbs in Damana, A Chibchan language of northern Colombia. As shown through a careful analysis of eleven verbs, the verbal system of Damana primarily encodes spatial relations and does not classify objects by shape.

Secondly, I show that the same object can be freely associated with various verb stems depending on the object's orientation. Thirdly, in metaphorical extensions involving these 'noun class' verbs, it is a …
