Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to investigate brightness constancy in schizophrenic patients. Two schizophrenic groups, one chronic and one acute, and three control groups, non-schizophrenic psychiatric patients, hospitalized tuberculous patients, and normal volunteers from the hospital staff were used as subjects. The Brunswik and Thouless ratios were used as the index of constancy and matches were made by the subjects on a differential color mixer. It has been suggested that brightness constancy is really a special case of brightness contrast. This possibility was discussed and it was concluded that most brightness constancy effects can be accounted for by contrast mechanisms. However since it has been demonstrated that constancy can be obtained in situations where contrast is inoperable, it is very likely that there may be additional central mechanisms operating in constancy. It was further concluded that these mechanisms operating in brightness constancy are more primitive than those operating in size, shape, and distance constancies. Since many studies (e. g. Lovinger 1956, Weckowicz 1964) have reported reduced size, shape, and distance constancies in schizophrenic patients it was predicted that brightness constancy would also be reduced in schizophrenic illness. The results provided no confirmation for the prediction. Schizophrenic patients apparently do not differ significantly from control groups in brightness constancy. However the results do suggest responses of schizophrenic patients may be significantly more variable than controls in this situation. It was also found that schizophrenic patients tended to mix significantly more white color when making their matches of the standard and variable discs under the reduction screen condition. Possible causes of this unexpected behavior were considered. In the discussion of the results an attempt was made to explain the possible reason why brightness constancy is not affected in schizophrenic patients while size, shape, and distance constancies are reduced. After reviewing the pertinent evidence, it was suggested that brightness constancy is based on more primitive perceptual mechanisms than those in size, shape and distance constancies and therefore is not disturbed in schizophrenic illness.

Available in PDF, EPUB and Kindle. Book excerpt: Feelings of Being is the first ever account of the nature, role and variety of 'existential feelings' in psychiatric illness and in everyday life. There is a great deal of current philosophical and scientific interest in emotional feelings. However, many of the feelings that people struggle to express in their everyday lives do not appear on standard lists of emotions. For example, there are feelings of unreality, surreality, unfamiliarity, estrangement, heightened existence, isolation, emptiness, belonging, significance, insignificance, and the list goes on. Ratcliffe refers to such feelings as 'existential' because they comprise a changeable sense of being part of a world In this book, Ratcliffe argues that existential feelings form a distinctive group by virtue of three characteristics: they are bodily feelings, they constitute ways of relating to the world as a whole, and they are responsible for our sense of reality. He explains how something can be a bodily feeling and, at the same time, a sense of reality and belonging. He then explores the role of altered feeling in psychiatric illness, showing how an account of existential feeling can help us to understand experiential changes that occur in a range of conditions, including depression, circumscribed delusions, depersonalisation and schizophrenia. The book also addresses the contribution made by existential feelings to religious experience and to philosophical thought.
