Although the phenomenological diversity of hallucinations has been well documented, experimental investigations into their cognitive underpinnings have not yet reflected this complexity. Our goal in this review is to contrast the restricted set of experimental conditions that have been utilized in source-monitoring studies of hallucinations with their documented phenomenological diversity. In particular, we initially focus on the theoretical distinction between origin and source that has been recognized at the level of phenomenology, and then review the source-monitoring literature within this theoretical framework. In addition, we touch on several other aspects of the phenomenological diversity of hallucinations that have not yet been sufficiently investigated experimentally-namely, intentionality, affect, and motivational factors. Finally, we list other methodological problems that may have led to inconsistencies in the literature. We conclude with concrete recommendations for future source-monitoring investigations of hallucinations. [less ▲]

INTRODUCTION: Studies suggest an important role of disturbances of self in schizophrenia and in schizotypy. Based on findings from a previous study (Bredart & Young, 2004), we developed a questionnaire assessing self-face recognition failures in everyday life (Self-Face Recognition Questionnaire; SFRQ) to investigate the relations between dimensions of schizotypy (cognitive-perceptual, interpersonal, disorganised) and self-face recognition disturbances. METHODS: A sample of nonclinical participants (n = 170) completed the SFRQ and the Schizotypal Personality Questionnaire. RESULTS: Factor analysis of SFRQ items revealed a clear three-factor structure consisting of: (1) self-face recognition difficulties, (2) unusual perception of own or other faces, and (3) other-face recognition difficulties. Correlational analyses between schizotypy dimensions and the SFRQ revealed that only the cognitive-perceptual and disorganised schizotypy dimensions correlated significantly with the SFRQ. By contrast, the interpersonal schizotypy dimension was not associated with the SFRQ. CONCLUSIONS: Findings provide further support that positive (cognitive-perceptual) and negative (interpersonal) schizotypy represent discrete neurobehavioural dimensions. The theoretical implications of these findings are discussed. [less ▲]

Numerous studies suggest a cognitive bias for threat-related material in delusional ideation. However, few studies have examined this bias using a memory task. We investigated the influence of delusion-proneness on identity and expression memory for angry and happy faces. Participants high and low in delusion-proneness were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been. Remember/know/guess judgments were asked for both identity and expression memory. Results showed that delusion-prone participants better recognised the identity of angry faces compared to non-delusional participants. Also, this difference between the two groups was mainly due to a greater number of remember responses in delusion-prone participants. These findings extend previous studies by showing that delusions are associated with a memory bias for threat-related stimuli. [less ▲]

Impulsivity is an important and multifaceted psychological construct. Recently, Whiteside and Lynam (2001) have developed the UPPS Impulsive Behavior Scale that distinguishes four dimensions of impulsivity: Urgency, lack of Premeditation, lack of Perseverance, and Sensation seeking. In the present study, we investigated the psychometric properties of a French adaptation of the UPPS Impulsive Behavior Scale. Two hundred and thirty-four undergraduate students completed the UPPS Scale. Exploratory and confirmatory analyses revealed a four factors solution similar to that found in the original study. Also, the results indicated that there was good to very good internal reliability for the four subscales. [less ▲]

Hallucinatory experiences in nonclinical subjects were examined using a French adaptation of a self-report questionnaire (Launay-Slade Hallucinations Scale; LSHS). The factor structure of this questionnaire was examined. In addition to prevalence, we explored various characteristics of the reported hallucinatory experiences, including frequency, degree of control, emotional reaction, relationship to stressful events, and personal saliency. We also examined the relationship between the presence of hallucinatory experiences and other factors, such as substance use and social desirability. Two hundred and thirty-six nonclinical participants completed a modified version of the LSHS, a social desirability scale, and answered follow up questions. Factor analysis of the present version of the LSHS revealed a five-factor structure. Results regarding participants' hallucination frequency, perceived levels of control, and affective responses are reported. Additional results and implications are discussed. [less ▲]

INTRODUCTION: In the present study we explored the role of cognitive factors in hallucinatory proneness by utilising an incidental source monitoring task consisting of actions. METHOD: A total of 65 normal subjects were administered a source monitoring task and were asked either to: (1) perform the action; (2) watch the experimenter perform the action; (3) imagine him/herself performing the action; (4) imagine the experimenter performing the action; (5) or listen to the experimenter say the action verbally. Following a delay, actions were presented consisting of those already presented in one of the 5 conditions (old), and those never before presented (new). For each action, subjects were required to identify if the action was old or new. If the action was identified as old, subjects were required to identify the source of the word (i.e., one of the 5 conditions). Subjects also completed a questionnaire assessing metacognitive beliefs. 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 = 16), whereas scores within the lower 25% were included in the nonhallucination-prone group (NHP) (n = 16). RESULTS: Within the internal conditions, hallucination-prone subjects confused two internal sources (a specific internal-internal source discrimination error). That is, for imagined actions where the subjects performed the action, HP subjects erroneously attributed these towards an imagined action performed by the experimenter. Results also revealed that hallucination-proneness was associated with metacognitive beliefs. Finally, there was a significant relation between certain metacognitive beliefs and the internal-internal source discrimination error on the source monitoring task. CONCLUSIONS: Findings from the present study suggest that an important cognitive deficit in the genesis of hallucinations may be a perturbation in the control of interna [less ▲]

Few studies have explored the prevalence of hallucinations in the non-clinical, elderly population. Also, the association between personality structure and hallucinations remains poorly investigated. The aims of the present study were twofold. First, to explore the influence of age on the prevalence of hallucination-proneness, and second, to examine the association between personality and hallucination-proneness in young and elderly subjects. A sample of young (n = 230) and elderly adults (n = 183) completed an elaborated and validated version of the Launay-Slade Hallucinations Scale (LSHS; Laroi, Marczewski, & Van der Linden, 2004) and the Five Factor Inventory version of the NEO Personality Inventory (NEO-FFI; Costa, [less ▲]
