“…Patients with passivity phenomena, however, were the only group who showed unconstrained duration of imagined movements, suggesting a specific impairment in motor imagery in these patients. Similar findings were also reported with a visually guided pointing task [25] and a mental rotation task [26].…”

“…Second, most studies do not permit an assessment of the deficits in patients with delusions of control compared with patients with hallucinations, as they typically group together patients that manifest either delusions, hallucinations, or both these symptoms [10,17,19,20,23,[33][34][35][36]. In spite of these difficulties, several studies have found SM impairment specifically associated with delusions of influence (passivity delusions, alien control) [9,21,24,37,38] or hallucinations [16,18,26]. Impaired performance on SM tasks has, however, also been observed in patients without FRS [39][40][41][42][43].…”

Many patients suffering from schizophrenia feel dispossessed from some of their actions or thoughts. This dispossession could result from impaired self-monitoring (SM), defined as the ability to monitor self-willed intentions and actions. SM has been widely studied during the past decades with very different paradigms; central error correction, feedback distortion, sense of effort, and motor imagery. The present article first reviews the methods used and results obtained in investigation of SM. Second, we address what we consider to be the critical questions that must be answered in order to fully understand the role of SM deficit in schizophrenia: 1) Is SM deficit only impaired in patients with specific symptoms? 2) Is SM deficit associated with other cognitive processes that are also impaired in patients with schizophrenia? 3) Can SM impairment be characterized as a trait or a state marker? Finally, we discuss the consequences of SM investigation on diagnostic evaluation and therapeutic orientations and we propose future research that we think is essential in order to clarify the role of SM in schizophrenia.

“…Although the authors indicated that people can voluntarily adopt one or the other method, we are inclined to think that motor simulation is more likely to be initiated in certain situations, such as the priming of manual activity. A subsequent study (de Vignemont et al, 2006) provided further evidence for this postulation. In this study, gloves were used as the stimuli to be mentally rotated, and participants were explicitly instructed to place their hands in the gloves.…”

A letter on a hand: Rotating together or separately?

The motor system plays a role in some object mental rotation tasks, and researchers have reported that people may use a strategy of motor simulation to mentally rotate objects. In this study, we used images of a hand with a letter printed on the palm to directly determine whether a hand image can be automatically rotated during the deliberate mental rotation of an object and whether the hand and object are rotated in the same trajectory. A total of 41 participants were shown the stimuli and asked to decide whether the letters, which were upright or tilted at specific degrees, were normal or mirrored. The hand images in the background showed either a left or a right hand in the palm view, with fingers pointing upwards, medial, downwards, or lateral. Reaction times and error rates were measured to determine the speed and accuracy of mental rotation. A complex interaction between the hand posture and letter orientation revealed that the hand image was mentally rotated automatically, together with the deliberate mental rotation of the letter. The biomechanical constraints of the hand also influenced reaction times, suggesting the involvement of the motor system in the concomitant mental rotation of the hand image. Consistent with the motor simulation theory, the participants seemed to imagine the hand carrying the object in its movement. These behavioural data support the motor simulation theory and elucidate specific processes of mental rotation that have not been addressed by neuroimaging studies.

“…This test primarily assesses visuospatial intuition. Schizophrenia patients have also been reported to be impaired in this task [6,11]. Unfortunately, few studies have discussed whether this task satisfies the other criteria for an endophenotype, although some gene polymorphisms have been reported to be associated with performance on this task [4].…”

a b s t r a c tRs9722 and rs1051169 have been reported as affecting the levels of S100B in the serum or the brain, and haplotypes containing these two SNPs have been associated with schizophrenia. The current study investigated the role of the S100B gene in an endophenotype of schizophrenia-spatial disability. 304 schizophrenia patients and 196 healthy controls were given a block design task and a mental rotation task. Results showed that the two aforementioned SNPs and related haplotypes were associated with the spatial disability of schizophrenia patients. Specifically, risk factors for the elevated S100B levels, including the A allele of rs9722, the G allele of rs1051169, and the AG haplotype, were associated with a poorer performance on both tests of spatial ability, especially the mental rotation task. These results implicate a role for S100B gene polymorphisms in the cognitive functions of schizophrenia patients and encourage further investigation into spatial disability as an endophenotype of schizophrenia.
