Connecting neurosis and psychosis: the direct influence of emotion on delusions and hallucinations

Diagnostic classification systems contain a core divide between neurosis and psychosis, leading to their separate study and treatment. The basis for the separation of the disorders is outlined and reassessed. It is argued that the empirical evidence does not support such a sharp distinction between neurosis and psychosis. The frequent occurrence of emotional disorder prior to and accompanying psychosis indicates that neurosis contributes to the development of the positive symptoms of psychosis. Psychological theories and experimental evidence concerning the influence of emotion on the content and form of delusions and hallucinations are therefore reviewed. It is argued that in many cases delusions are a direct representation of emotional concerns, and that emotion contributes to delusion formation and maintenance. The content of hallucinations less often directly expresses the emotional concerns of the individual, but emotion can trigger and contribute to the maintenance of hallucinatory phenomena, although how this occurs is not well understood. It is concluded that study needs to be made of the interaction between psychotic and neurotic processes in the development of delusions and hallucinations, and that neurotic and psychotic disorders may have common maintenance processes.     

Reflections on trauma,symbolization and psychic pain in a case of neurosis and a case of psychosis

This paper seeks to advance some considerations on trauma, historical reality, its symbolization and the psychic pain generated by the investigation of unconscious processes in psychoanalytic treatment. These themes will be explored by demonstrating the differences arising between traumatic experiences and their expression in phantasy, as they occurred in a case of neurosis and another of psychosis. In each case, the differences in the features of the symbolization and the processes of working through shall also be taken into consideration. Particular attention shall be paid to the specific difficulties encountered by the analyst in the interpretative treatment of the trauma resulting from the amount of psychic pain induced in the patient, which at times proves to be an insurmountable barrier and a destructive distortion of the process.     

Premorbid personality indicators of schizophrenia-related psychosis in a hypothetically psychosis-prone college sample

Bolinskey, P. K. & Gottesman, I. I. (2010). Premorbid personality indicators of schizophrenia-related psychosis in a hypothetically psychosis-prone college sample. Scandinavian Journal of Psychology, 51, 68–74.
Research into psychosis proneness has established the Chapman Psychosis Proneness Scales (CPPS), certain personality disorders, certain response patterns on the MMPI-2, and social withdrawal as being valid indicators of liability. The current study extends our understanding of premorbid indicators of schizophrenia-related psychosis (SRP) by examining whether individuals identified as hypothetically psychosis prone (HPP) by virtue of their CPPS scores also show differences on other premorbid indicators of SRP. Results indicate that HPP individuals evidence more deviancy in the schizophrenic direction. By providing additional construct validity for the CPPS and other endophenotypic indicators of premorbid processes, strategies for understanding the development of SRP are enhanced.     

Association of Rorschach and MMPI psychosis indicators and schizophrenia spectrum diagnoses in a Russian clinical sample

In this study, I investigated the relationships among psychological test variables and schizophrenia spectrum diagnoses in a Russian sample of 180 psychiatric patients. Schizophrenia is understood somewhat differently in Russia than in the West. Analyses compared Rorschach (SCZI, PTI; Exner, 2001) and MMPI (Berezin, Mitroshinkov, & Sokolova, 1994) psychosis indicators (Sc, Sc3, Sc6, and BIZ) and 3 diagnostic systems: (a) Russian traditional, (b) the Russian-modified International Classification of Diseases (9th ed. [ICD-9]; Ministerstvo Zdravokhraneniya SSSR, 1982), and (c) the nonmodified ICD-10 (World Health Organization, 1992; comparable to the Diagnostic and Statistical Manual of Mental Disorders [4th ed.], American Psychiatric Association, 1994). Results showed modest support for the SCZI and PTI but not the MMPI indicators. While the field awaits further evidence, psychologists should proceed with caution when using the Rorschach and MMPI to assess for psychosis among Russians.     

A comparison of Rorschach developmental level and form-level systems as indicators of psychosis.

Psychotic and nonpsychotic psychiatric inpatients were tested on the Rorschach. "Reality-testing" was measured by four form-level scoring systems designed by Beck, Mayman, Becker, and Wilensky. The psychotic subjects were dichotomized on three diagnostic dimensions: schizophrenia, paranoia, and premorbid social adjustment. No significant differences were found for the Beck system. With the other systems, psychotics showed significantly poorer reality testing than nonpsychotics. No differences were found for the schizophrenic and paranoid dimensions. The Phillips premorbid adjustment score was negatively correlated with all four measures of "reality-testing." The conclusion drawn was that Rorschach measures of "reality testing" are associated with psychotic and poor premorbid functioning, but do not differentiate schizophrenic from nonschizophrenic psychotics or paranoid schizophrenics from nonparanoid schizophrenics.     

Prognostic indicators for stuttering: the value of computer-based speech analysis

There are currently no known acoustic parameters by which stuttering children can be appraised in order to predict the further course of their speech disfluency. The present study investigates the usefulness of a computer-based speech analysis of fluent utterances. Correlations between acoustic variables, severity, and course of stuttering were sought in a prospective longitudinal study. This analyzed 57 preschool children at 6-month intervals over a period of 4.6 years. The acoustic analyses yielded no clearly distinguishing characteristics. There was, however, one subgroup consisting of children who were still disfluent at study end which showed more variable values at various measurement points for different parameters. Speech control seems to be different in children exhibiting chronic stuttering.
