„Movement reactions” in the Hermann Rorschach Test. Part 2 Testing parents of a child suffering from schizophrenia and parents of healthy children

Abstract

Introduction: The specific character of Rorschach test responses of parents who had a child with schizophrenia has been reported many times. The analysis presented in this paper is focused on responses commenting on movement seen in the inkblots. According to Zygmunt Piotrowski, these responses reflect the prototypal role – self-concepts and a certain pattern of responding that can be understood as phenomena related to the concept of self.

Material and method: I used the Rorschach test to examine 32 couples of parents who had a child suffering from paranoid schizophrenia (as defined in DSM-IV) and 21 couples of parents who had only healthy children.

Results: Parents of schizophrenic children gave significantly fewer human movement responses than parents of healthy children, and some features of these responses give them a specific character. The groups of fathers differed from each other to a greater degree than the groups of mothers. The analysis of relationships between movement responses and shading (chiaroscuro) responses, which are regarded as a measure of anxiety, revealed significant associations in the case of some movement qualities. The exception was that movement quality which is referred to as blocked movement and blocked-posture movement in Piotrowski’s interpretive scheme. All movement qualities globally considered were significantly correlated with anxiety, the exceptions being the group of parents of healthy children and the group of all fathers.

Discussion: The smaller number of human movement responses found in the group of parents of schizophrenic children may attest to these people’s lower psychological maturity, which is associated with a less distinctly formed prototypal role. Moreover, certain specific features of these responses can be interpreted as a sign of difficulties in expressing this role. The cooccurrence of movement responses with shading responses, which are treated as a sign of anxiety, was not always consistent with expectations; this should be considered a reason to reflect on the psychological meaning of these responses and on the possible return to Rorschach’s original views.

Conclusions: The results of the study suggest lower maturity in the case of parents of schizophrenic children, manifesting itself in a less strongly developed prototypal role and certain difficulties in expressing this role. Based on the analysis of the cooccurrence of movement responses and responses commenting on the shading present in the inkblots, it is possible to conclude that there is a need for a new psychological interpretation of these responses.

Analysis of independent components of cognitive event related potentials in a group of ADHD adults

Abstract

In the last decade, many studies have tried to define the neural correlates of attention deficit hyperactivity disorder (ADHD). The main aim of this study is the comparison of the ERPs independent components in the four QEEG subtypes in a group of ADHD adults as a basis for defining the corresponding endophenotypes among ADHD population.

Sixty-seven adults diagnosed as ADHD according to the DSM-IV criteria and 50 age-matched control subjects participated in the study. The brain activity of the subjects was recorded by 19 channel quantitative electroencephalography (QEEG) system in two neuropsychological tasks (visual and emotional continuous performance tests). The ICA method was applied for separation of the independent ERPs components. The components were associated with distinct psychological operations, such as engagement operations (P3bP component), comparison (vcomTL and vcom TR), motor inhibition (P3supF) and monitoring (P4monCC) operations.

The ERPs results point out that there is disturbance in executive functioning in investigated ADHD group obtained by the significantly lower amplitude and longer latency for the engagement (P3bP), motor inhibition (P3supF) and monitoring (P4monCC) components. Particularly, the QEEG subtype IV was with the most significant ERPs differences comparing to the other subtypes.

In particular, the most prominent difference in the ERPs independent components for the QEEG subtype IV in comparison to other three subtypes, rise many questions and becomes the subject for future research.

This study aims to advance and facilitate the use of neurophysiological procedures (QEEG and ERPs) in clinical practice as objective measures of ADHD for better assessment, subtyping and treatment of ADHD.
