The aims of this project were (1) to investigate two forms of event perception: perception of movement and perception of sudden appearance, (2) to develop event perception procedures which could be applied to testing clinical populations, and (3) to relate event perception to abnormalities shown by neuroimaging. In addition issues relevant to each of the particular clinical populations involved were addressed. Event perception tasks used stimuli consisting of a background of randomly selected dots of light. In one task a dot was added to the display (appearance), in the other a dot started to move (movement onset). Four laboratory experiments were conducted examining the ability to detect and locate these events under varying conditions in healthy controls. Results indicated that neuronal coding strategies were different for appearances and movement onset. Laboratory tasks were adapted for clinical application and administered to groups of patients with different neurological conditions. Five studies were conducted to assess sensitivity and specificity of the Event Perception tasks in clinical settings. The groups studied were chronic solvent abusers, detoxified alcoholics, patients suffering from optic neuritis, and patients with traumatic brain injury. Event Perception tasks were found to be differentially sensitive to neurological conditions and showed dissociations and double dissociations both within and between neurological conditions. Relationships with Magnetic Resonance Imaging (MRI) and Single Photon Emission Computed Tomography (SPECT) were investigated in patients with head injury. Patterns of brain damage differed significantly for patients with impaired performance on the movement task. It is concluded that Event Perception tasks are of value in the assessment of neurological patients: They allow assessment of functions which are not usually evaluated in neuropsychological examinations, facilitate detection of subtle deficits and deficits which may present at an early stage, and offer greater specificity and sensitivity than many traditional neuropsychological test procedures. Event Perception tasks are easy to administer and do not suffer from training effects on repeated administration to the same degree as many traditional measures. It is also argued that tests with a theoretical basis are better suited to clinical research in neuropsychology than many traditional tasks because they potentially allow a more precise explanation and assessment of the abnormal processes under investigation.

1 ABSTRACT The aim of the thesis is to look on the impact of legislative framework on practice through the eyes of social workers in department of child protection. The point is approach the practice of this profession and impact of legislative to it, which can affect both the client and the worker. The theoretical part of the thesis presents legislative framework, which limits practice of department of social protection. There is summarize The Constitution of the Czech Republic, the Charter of Fundamental Rights and Freedoms, the United Nations Convention on the Rights of the Child, social and legal protection of children's law and Administrative Procedure Code. Than in this chapter are processed gestation responsibilities related to child protection. The second chapter processed discourses in social work by Karen Healy (2005). The third chapter specifies legislative framework in selected parts of child protection. These are, for example, areas of guardianship ad litem, foster care, adoption, institutional care and curator for children and youth. The chapter is conclude by description of standards of quality for the department of child protection. In the fourth chapter is pointed out position of child protection in legal system of the Czech Republic. Thera are rights and obligations for employees, which...
