Recent years has seen an increasing interest in the hallucinatory experience, including investigations of its phenomenological prevalence and character both in pathological and normal (predisposed) populations. We investigated the multi-dimensionality of hallucinatory experiences in 265 subjects from the normal population, who completed a modified version of the Launay-Slade Hallucinations Scale. Principal components analysis was performed on the data. Four factors were obtained loading on items reflecting (1) sleep-related hallucinatory experiences (2) vivid daydreams (3) intrusive thoughts or realness of thought and (4) auditory hallucinations. The results offer further evidence of the multi-dimensionality of hallucinatory disposition in the normal population. Directions for future research in hallucinatory predisposition are discussed. <LF>(C) 2003 Elsevier SAS. All rights reserved. [less ▲]

Symptoms of psychosis have been proposed to form part of a continuous distribution of experiences in the general population rather than being an all-or-nothing phenomenon. Indeed, schizotypal signs have been reported in subjects from nonclinical samples. Emotional processing has been documented to be deficient in schizophrenia. In the present study, we tested the hypothesis whether putatively psychosis-prone subjects would show abnormalities in emotion processing. Based on the extremes of Launay-Slade Hallucination Scale (LSHS) ratings of 200 undergraduate students, two groups of subjects (total N= 40) were selected. All 40 participants filled in the Schizotypal Personality Questionnaire (SPQ). We compared both groups on an alexithymia questionnaire and on four behavioral emotional information processing tasks. Hallucination-proneness was associated with an increased subjective emotional arousal and fantasy-proneness. Although no differences between the high and low group were observed on three behavioral emotion processing tasks, on the affective word-priming task presentation of emotional stimuli was associated with longer reactions times to neutral words in high schizotypal subjects. Also, SPQ scores correlated with several emotion processing tasks. We conclude that these findings lend partial support to the hypothesis of continuity between symptoms characteristic of schizophrenia and psychosis-related phenomena in the normal population.

Objectives. A tendency to externalize internal information on reality monitoring tasks has been documented in psychiatric patients with hallucinations. Furthermore, previous studies suggest that factors such as the emotional salience of the material, cognitive effort and meta-cognitive beliefs are important contributory factors in this tendency to externalize internal information on reality monitoring tasks. However, few studies have investigated these aspects in hallucination-prone subjects. Also, these factors have never been examined simultaneously. In the following study we wished to examine the effects of emotional salience, cognitive effort and meta-cognitive beliefs on reality monitoring functioning in hallucination-prone subjects. Design. Between-participants group design. Method. One hundred normal subjects were administered a reality monitoring task. Words were presented by the experimenter. After each word, subjects were asked to say the first word that came to their mind. Words varied in terms of emotional valence and cognitive effort (high cognitive effort for words requiring longer latency times to associate a word and vice versa). Following a delay, words were presented consisting of those already presented by the experimenter or the subject (old) and those never presented before (new). For each word, subjects were required to identify whether the word was old or new. If the word was identified as old, subjects were required to identify the source of the word (subject or experimenter). Subjects also completed a questionnaire assessing meta-cognitive beliefs. Results. Subjects were grouped according to their scores on a revised and elaborated version of the Launay-Slade Hallucinations Scale (LSHS). Those with scores within the top 25% were included in the hallucination-prone group (HP) (N = 25), whereas scores within the lower 25% were included in the non-hallucination-prone group (NHP) (N = 25). Results showed that the HP subjects had significantly more source discrimination errors than NHP subjects for self-generated items. In other words, HP subjects tended to misattribute to the experimenter items that they had produced themselves. This pattern was especially marked with emotionally charged material and with words that required more cognitive effort. In addition, HP subjects scored significantly higher on a scale assessing meta-cognitive beliefs compared with NHP subjects. Finally, scores on a scale assessing meta-cognitive beliefs were positively associated with source discrimination errors. Conclusions. These results suggest that cognitive effort, emotional salience and meta-cognitive beliefs all play a prominent role in the externalizing bias in hallucination-prone subjects. The results also provide evidence for the validity of the idea of a continuity between hallucination-prone subjects and psychotic patients with hallucinations on reality monitoring tasks, including a number of contributing factors in the occurrence of hallucinations.

Although brain injury may have a great impact on the family as a whole, family reactions are not adequately addressed in rehabilitative programmes. When they are, treatment tends to be approached from a family education and support perspective and not from a family therapy perspective. The aim of the following paper is to illustrate the important role that a family systems approach can play in treating families of individuals with brain injury. In particular, clinical examples taken from the literature will be presented that illustrate how family roles can be modified as a consequence of a brain injury, and the importance of re-establishing or re-distributing these roles. It will be argued that an intimate collaboration between family therapist and brain injury professional is essential, and that the ideal professional make-up of clinicians working with families of persons with brain injury are those well-versed in both brain injury rehabilitation and family therapy.

Investigated supervisory attentional system (SAS) functions in schizophrenic patients. 15 schizophrenic outpatients (mean age 29.93 yrs) and 15 normal controls matched for age, gender, and educational level were compared. Three tasks (Tower of London, Hayling, and Brixton tests) were used to examine 3 executive processes (planning, inhibition, and rule detection). Schizophrenic patients performed significantly worse than normal controls on all 3 tasks. In addition, patients' performances on selected measures of the three tests were correlated, even when age and medication were partialled out. It is concluded that patients are impaired on all SAS functions. The possible role of a general impairment (processing speed or cognitive resources) is discussed [less ▲]

In recent years an increasing interest in attributional style in both normal and pathological populations has developed. In that context, the Internal, Personal and Situational Attributions Questionnaire (IPSAQ) was constructed. We investigated the psychometric properties of a French translation of the IPSAQ in a normal population.The results offer evidence that the present french translation has similarly adequate psychometric porperties as the original english version [less ▲]

A traumatic brain injury may have a great impact on the family as a whole and may include changes in the family's organizational structure, communication patterns, or balance of family needs. In spite of this, treatment strategies for these problems are only slowly being recognized, resulting in either family reactions being inadequately addressed in rehabilitative programs, or treatment being approached from a family support perspective and not from a family therapy perspective. The aim of the following paper is to illustrate how family therapeutical approaches can be used in treating families of individuals with brain injury, in particular, structural interventions. Clinical examples will be presented where structural interventions were utilized with brain injury patients and their families. Other inverventional approaches from family therapy will also be mentioned. [less ▲]
