Little is understood about the origins of atypical scanpath formation in schizophrenia.  This thesis presents a series of novel investigations which aimed to characterise the viewing abnormality and its correlate in schizophrenia and to investigate a range of putative causal mechanisms. Individuals with schizophrenia and non-clinical comparison participants completed smooth pursuit and ocular fixation tasks, mood assessment scales and free-viewing of novel visual stimuli.  Patients also completed detailed clinical and neurophysical assessment. Results replicated findings of a ‘restricted’ style of visual scanning schizophrenia, characterised by reduced fixation and saccade frequency, increased fixation durations and reduced scanpath length.  Patients also demonstrated increases in medial saccade amplitude, duration and peak velocity relative to non-clinical viewers.  Viewing abnormalities were only minimally associated with clinical and demographic variables, occurred irrespective of the nature of the stimulus and conveyed high sensitivity and specificity in distinguishing cases from controls. Two studies manipulated attention to the viewing task in non-clinical viewers and patients respectively and suggested atypical scanning is not entirely attributable to diminished task engagement.   Restricted scanning was associated with both heightened anxiety and increased interference by irrelevant visual features during fixation.  A possible causal role of anxiety on distractibility and thus scanpath formation is tentatively proposed.  Restricted scanpaths were associated with dimensions of neurocognitive functioning including working memory, short term verbal memory and verbal fluency.  These patterns are argued to be consistent with a role of dysfunction of the dorsolateral prefrontal cortex in atypical scanpath formation.  Finally, scanpath dysfunction was found to occur independently of impairments in smooth pursuit performance, suggesting the independence of neuroanatomical bases for these deficits.

Thesis (M.Cur) --University of Limpopo, 2013 / Adherence to antipsychotic medication is very important to patients with schizophrenia. Therefore, if patients with schizophrenia are non-adherent to treatment, they are at risk of relapse and being re-admitted at a mental health care institution in the Limpopo Province. Despite the proven benefits of antipsychotic medications, half of the patients with schizophrenia do not take their prescribed drugs. The researcher has observed the following occurrences during practice: • Lack of adherence to antipsychotic medications of schizophrenic patients results in symptoms not being relieved, poor drug effectiveness and patients developed other serious or costly consequences, such as being violent and damaging property; • High rate of relapse; and • High rate of re-admissions. This research questions has guided the study: • What are the factors affecting adherence of mentally stable schizophrenic patients to antipsychotic medications at a mental health institution in the Limpopo Province? • Do mentally stable schizophrenic patients adhere to prescribed treatment? • Are there any guidelines used to promote adherence to antipsychotic treatment? The aim of the study has been to determine the level of adherence of mentally stable schizophrenic patients to antipsychotic medication at a mental healthcare institution in the Limpopo Province. The objectives of the study have been to describe adherence of mentally stable schizophrenic patients to antipsychotic medication at a mental health institution in the Limpopo Province. It implies that participants have been given the opportunity to describe their experience while on medication. vi Their responses have led to the development of guidelines to promote adherence of mentally stable schizophrenic patients to antipsychotic medication. The study site has been the Thabamoopo Mental Healthcare Institution in the Capricorn District of the Limpopo Province. A descriptive, exploratory and contextual qualitative research design has been used in this study. The population has consisted of all mentally stable schizophrenic patients and all the carers of such patients. Non-probability purposive sampling has been used to select participants in this study. The researcher has used a semi- structured interview with two schedule guides for the patient and carers/relatives, which have specified the issues and questions covered. It has assisted the researcher with gathering information about the problem studied (De Vos et al. 2005).A total of twenty (n = 20) participants, consisting of fourteen (n = 14) mentally stable schizophrenic patients and six (n = 6) carers/relatives has been included voluntarily in the semi-structured interview sessions. The steps of data analysis as described by Tesch (1990) in Cresswell (1994) have been followed in this study. The findings of this study reveal a central storyline which indicates that participants share the same point of view in connection with aspects of adherence to antipsychotic treatment and also knowledge about the causes of mental illness and its prognosis. The following four themes and their sub-themes have emerged during data analysis: Theme 1: Participants share the same point of view related to aspects of adherence to antipsychotic treatment; Theme 2: Knowledge related to mental illness; Theme 3: Health seeking behaviours of mentally ill patients; and Theme 4: Experiences of relatives caring for mentally stable patients on treatment. Guidelines and recommendations based on the findings of this study are described in Chapter 4. The criteria for establishing the trustworthiness of qualitative data maintained in this study have been: Credibility, dependability, confirmability and transferability. The following ethical principles have been adhered to: The principle of beneficence, justice, the principle of human respect and dignity, permission to conduct the study, informed consent and confidentiality, privacy and anonymity.

Concerning the present study, if in the test result of psychotic patients there is some distortion of reality concepts, as is generally expected, then their scores on any personality scale should vary considerably from norms established on the same test by "normal" subjects.

The main question of the research is what orality was found in schizophrenia? In this case, a schizophrenic patient expresses its pathos also through orality, to ingest objects, especially metals. Through research were traced ideas on how the meeting between schizophrenia and orality occurs. From the concept of schizophrenic orality, it is possible to think of the originality of schizophrenia and its implications on their way of being in the world, creatively and destructively. It is thought in a mouth-body, which features a mangling on the body schema, making it without representation. The schizophrenic orality consists initially in the first oral phase where the person was a receptacle of partial objects; being that, it does not become possible to make the necessary path for the total objects and differentiation with each other. So the schizophrenic ends up relating in a disintegrated way with the objects of the world and with others, including the schizophrenic orality. The clinician while attending schizophrenic patients should consider schizophrenic orality because it is a manifestation that says a lot about the pathos, with a possible opening for creativity on clinical activity aiming a lower destructiveness in these patients / Esta dissertação propõe investigar a manifestação da oralidade e suas implicâncias na esquizofrenia. A questão propulsora da pesquisa é: qual oralidade encontra-se na esquizofrenia? No caso em questão, um paciente esquizofrênico manifesta seu pathos também através da oralidade, ao ingerir objetos, sobretudo metálicos. Através da pesquisa traçaram-se ideias sobre como ocorre o encontro entre esquizofrenia e oralidade. A partir do conceito de uma oralidade esquizofrênica, pode-se pensar na originalidade da esquizofrenia e suas implicâncias sobre sua forma de ser no mundo, criativa e destrutivamente. Pensa-se em uma boca-corpo que apresenta uma desconfiguração no esquema corporal, tornando-a sem representação. A oralidade esquizofrênica é constituída inicialmente na primeira fase oral, onde o Eu é um receptáculo de objetos parciais; assim, torna-se impossível fazer o caminho necessário para os objetos totais e a diferenciação com o outro. Portanto, o esquizofrênico acaba por se relacionar de forma desintegrada com os objetos do mundo e com o outro, inclusive pela oralidade esquizofrênica; o clínico, ao atender os pacientes esquizofrênicos, deve considerar essa oralidade, pois trata-se de uma manifestação que diz muito sobre o pathos, sendo uma abertura possível para a criatividade na clínica visando uma menor destrutividade nesses pacientes
