Bibliography: pages 131-140. / Kinetic Family Drawings (KFDs) are Projective drawings which require the drawer to give 'action' to the depicted figures. A number of studies have been conducted following its inception in 1970. (Burns & Kaufman, 1970; 1972). Upon examination of these studies, however, it is evident that those studies pertaining to aspects of family functioning obtained significant results to a greater degree. It was the contention of the present study, that the KFD may be measuring aspects of family functioning. The present study thus incorporated a measure of family functioning, the McMaster Family Assessment Device (FAD) (Epstein, Baldwin & Bishop, 1983), to assess whether KFD depictions were indices of family functioning. The results were obtained through KFDs of 96 individuals who constituted 24 families. These individuals consisted of (n=48) parents and (n=48) adolescents. Due to constraints of research design, there were unequal numbers of males and females i.e. 38 males and 58 females.

The main purpose of this study was to examine the psychometric characteristics of the Bicycle Drawing Test. The 20-point scoring criterion was evaluated, and the preliminary norms were established. The Bicycle Drawing Test is an easily administered free-style drawing task that has been found to be a useful addition to a neuropsychological test battery. It provides a sample of visuopractic functioning involving the formation of a perceptual construct, a motor response, and a spatial component.

The present thesis explores the link between children's drawings and cognitive development. The aim of this study is to investigate the intellectual abilities of the child draughtsman with good depiction skills and to evaluate the merit of the drawing technique in the assessment of conceptual maturity. The standardised Goodenough-Harris Drawing Test (GHDT) of intellectual maturity was administered to 115 children between 4 to 8 years of age against criterion ability measures (Wechsler scales). Its psychometric properties are examined in respect to its norms and scales, its reliability and validity at different age levels and ranges of intelligence. Early theories in the area of pictorial representation were directed towards identifying features characteristic of different developmental periods (Kerschensteiner, 1905; Luquet, 1927/1977). At the same time Piaget and Inhelder (1948/1967) incorporated these stage theories into their model of spatial intelligence. Yet, the recent experimental study of children's drawings has disclosed a number of variables which interfere during the course of production, challenging the view that drawings can be seen as the royal route to access children's concepts. Stage theories are re-evaluated by means of fourteen experimental drawing tasks with various degree of difficulty. The tasks - administered to the same children tested with the standardised instruments -are spatial in nature and have been sampled from two widely researched areas related to the pictorial representation of partial occlusion and of spatial axes (horizontal/vertical). The acquisition of the pertinent spatial concepts by means of drawings is examined, considering competence-deficiency and competence-utilisation accounts of children's performance at different ages. Finally, overall perfomance on spatial tasks is compared with performance on conventional (Wechsler scales) and non-verbal (GHDT) measures of intellectual functioning, considering the optimum method to assess children's abilities by means of drawings. In general, drawing performance is reasonably sensitive to children's level of intelligence, yet the significance of drawing varies at different ages and ranges of IQ. Finally, the establishment of steadfast developmental trajectories falls short in the field of pictorial representation. The variable performance, particularly from the children at intermediate ages, suggests that the stages of intellectual or visual realism should be seen as relative and not as absolute.

The diploma thesis deals with the topic of limited normative data and its aim is to report the norms of the Clock Drawing Test (CDT) in a large sample of cognitively healthy Czech elderly (N = 501; aged 60 to 99). The CDT is a commonly used tool for screening of cognitive functions. We worked with the following version of test: clock drawing with pre- drawn circle and time setting 13.45 using three different scoring systems (Babins, Slater, Whitehead, & Chertkow, 2008; Cohen, Ricci, Kibby, & Edmonds, 2000; Shulman, Pushkar Gold, Cohen, & Zucchero, 1993). As a result, we found a significant effect of age and education, but non-significant effect of gender on CDT performance in old age. Therefore normative data was calculated considering those two demografical variables; the tables present means, standard deviations and t-scores based on defined subgroups. The results indicate that CDT performance of cognitively healthy elderly is negatively influenced by age, while directly proportional effect of education. Moreover it seems that the range of scores of the test grows with increasing age. Data collected in this thesis may be used for a more effective and standardized interpretation of CDT performance in old age in both clinical context and research. We also confirmed high inter-rater reliability...

ABSTRACT The discriminative ability and interrater reliability of one quantitative method of scoring Kinetic Family Drawings, (KFDJs), was explored, focusing on a little researched population - that of sexually abused versus non-referred Zulu speaking females between 7 and 11 years of age. An additional 20 indicators, suggested by various research to be frequent in the human figure drawings of (Western) sexually abused children, were also evaluated. The KFD's of 28 subjects were obtained. The 14 experimental group subjects were drawn from an organisation which deals extensively with the child survivors and perpetrators of sexual abuse. The 14 control group subjects were drawn from alocal primary school and had no known history of sexual abuse. Results were interpreted empirically. Results suggested that although the scoring system may be reliable, it is sensitive to the training, theoretical stance, etc. of the user. It was also suggested that the indicators used were not, as used by the scorers, able to distinguish between the KFDJs of the control and experimental groups. The relevance of certain of the indicators to South African populations was questioned since they were not scored at all by the scorers. In view of the researcher's perception of shortcomings with this approach, she attempted to describe more fully that which was depicted in the KFD's collected. Finally, several comments on the utility of viewing drawings from social constructivist, deconstructionist and social constructionist understandings as a complement to qualitative and quantitative approaches to the KFD were made. Suggestions as to how the KFD could be fruitfully used were proffered. It was contended that the KFD technique is not suitable for the use of lower level health care workers, that KFD's may have value in therapeutic settings, and that quantitative methods are simply one set of meanings which could be used to (partly) understand KFD's - attending to the child's context and the meanings he/she attributes to the various aspects of the KFD was contended to be important. / Thesis (M.Ed.) - University of Natal, Pietermaritzburg, 1999.

This thesis project examined the generalizabilty of the simplified scoring system for the Clock Drawing Test developed by Lessig and her colleagues in 2008 using a population-based sample. Clock-drawings from 356 participants (80 with dementia, 276 healthy controls) from the Canadian Study on Health and Aging were analyzed using logistic regression and Receiver Operating Characteristic curves. The new scoring system reduced the Lessig system down even further to include five critical errors: missing numbers, repeated numbers, number orientation, extra marks, and number distance, and produced a sensitivity of 81% and a specificity of 68%. The results from this study improve our current state of knowledge concerning the Clock Drawing Task by validating the simplified scoring system proposed by Lessig and her colleagues among a more representative sample and provides further evidence in support of a simple and reliable dementia-screening tool.

Alzheimer’s disease (AD) is a rapidly growing public health concern causing severe challenges to the health care system. Affecting the lives of more than 5 million Americans, it is characterized by brain-related morphological changes coupled with decrements in performance on tasks involving cognitive function such as those assessing memory and problem-solving abilities. Fortunately, current scientific research provides evidence that this trend towards rapid cognitive decline in older adults is not immutable, but rather can be attenuated through a simple adjustment to regular engagement in aerobic exercise. To date, numerous studies have associated regular cardiovascular exercise to changes in brain function and structure. In particular, aerobic exercise has been shown to have a direct effect on the hippocampus (HC), one of the earliest regions of the brain to be affected in AD, which plays an important role in learning and memory. Scientific research on animal models has demonstrated increased adult hippocampal neurogenesis (AHN), or the birth of new neurons, in the dentate gyrus (DG) subregion of the hippocampus as a response to increases in aerobic exercise. Such findings have led to the hypothesis that aerobic exercise can improve cognitive performance, more specifically hippocampal-dependent learning and memory, through the formation of new hippocampal neurons. Similarly, in human studies, previous research has shown that significant improvements in cardiovascular fitness are positively correlated with increased hippocampal volume. Structural increases in hippocampal volume are thought to be mediated by increased angiogenesis, or the generation of new blood vessels, which in turn are correlated with significant improvements in spatial memory, a task determined by memory function. The benefits of aerobic exercise, nonetheless, are not limited to the hippocampus. As people age, atrophy of the brain is also inclusive of the prefrontal cortex, a region implicated in planning and decision making. Scientific literature has shown, that similar to the hippocampus, increases in aerobic exercise, directly result to increases in grey matter volume in the prefrontal lobe and increases in white matter volume in the genu of the corpus callosum. Such structural changes in the prefrontal lobe are correlated with enhanced decision making on cognitive tasks, an essential component of executive function. For the purposes of this study, an effective method of evaluating whether changes in brain structure due to higher cardiorespiratory fitness have an association with cognitive function was through the administration of the Digital Clock Drawing Test (dCDT). The dCDT is a recently developed cognitive test based on the traditional Clock Drawing Test (CDT) that uses a digital pen and allows for the measurement of several parameters such as “Ink time” and “Think time.” Recent scientific studies report that such parameters may have a potential enhanced sensitivity to detecting cognitive change as compared to the traditional CDT. Therefore, the dCDT has come forward as an advantageous approach for testing cognitive skills in aging individuals such as those assessing executive and motor function, and semantic memory, as it happens in real time. DCDT parameters such as total time to complete the clock drawing, total ink time, total think time, total ink length, and clock size have been shown to differ significantly among subjects of varying degrees of cognitive impairment such as AD, mild cognitive impairment (MCI), and healthy, non-demented controls. Patients who were clinically diagnosed as cognitively impaired spent a greater amount of time thinking and drawing on both the command and copy clocks conditions as compared to healthy, non-demented individuals. Similarly, patients affected by greater cognitive impairments, such as AD, tended to draw smaller clocks in terms of height and width of the clock face that required less total ink length to complete the clock drawing, when compared to healthy controls and MCI participants. Findings showed that AD patients appeared to be working longer (greater time of completion) though producing less output (smaller clock and shorted ink length) as compared to non-impaired individuals. Variations of graphomotor latencies in the dCDT performance, therefore, are associated with individual’s cognitive capacities. The goal of this study is to investigate the associations between cardiorespiratory fitness based on VO2 max testing and cognitive constructs such as memory, executive function, and gross motor processing speeds as measured by graphomotor latencies and drawing patterns using the dCDT in healthy, non-demented older adults. I hypothesize that greater cardiorespiratory fitness will be negatively associated with graphomotor timed latencies in various parameters of the dCDT, given that exercise has known effects on the brain regions responsible for executive function and memory. To test these hypotheses, cardiorespiratory fitness and dCDT data from 12 sedentary older adults between the ages of 55 and 85 years from a larger study in the Brain Plasticity and Neuroimaging Laboratory at Boston University were collected and analyzed. A multiple regression analysis was used to predict the dCDT measures from individual’s cardiorespiratory fitness using estimated VO2 max levels. Results showed that cardiorespiratory fitness in older adults is inversely associated with graphomotor times in both the command and copy test conditions as predicted by our hypothesis. In particular, greater cardiorespiratory fitness was associated with shorter total ink time for both clock drawing testing conditions. These results held when controlled for age, sex, and education; higher cardiorespiratory fit older adults performed better (a shorter time is needed to achieve the same outcome) on tasks requiring greater cognitive constructs such as memory, executive function, and motor processing speeds. Therefore, it can be concluded that cardiorespiratory fitness may be a neurodegenerative protector in aging adults supporting its beneficial role as a therapeutic agent for cognitive decline in older adults.

The present study explored the possibility of applying Koppitz's developmental scoring techniques of mental maturity to retarded adults. The following hypotheses were tested: 1) that there is a significant correlation between the Koppitz HFD Test scores and the WAIS Full Scale scores; 2) that the correlation between the Koppitz HFD Test scores and the WAIS Performance Scale scores is also significant. Statistical computations did confirm the latter hypothesis but not the former one.
