OBJECTIVE To demonstrate that the classical calculation of Lempel-Ziv complexity (LZC) has an important limitation when applied to EEGs with rapid rhythms, and to propose a multiscale approach that overcomes this limitation. METHODS We have evaluated, both with simulated and real EEGs, whether LZC calculation neglects functional characteristics of rapid(More)
Retrieving information from long-term memory can lead people to forget previously irrelevant related information. Some researchers have proposed that this retrieval-induced forgetting (RIF) effect is mediated by inhibitory executive-control mechanisms recruited to overcome interference. We assessed whether inhibition in RIF depends on executive processes.(More)
Schizophrenic patients are known to exhibit inhibitory impairments in response suppression and selective attention. However, the impairment of inhibitory control in memory retrieval has not clearly been documented. In two experiments, we investigate inhibition in memory retrieval by using the retrieval practice procedure. In Expt 1, a cued recall final test(More)
Hallucinations have been recently associated with inhibitory deficits in memory. In this study, the authors investigated whether hallucinations were related to difficulties to inhibit irrelevant information from episodic memory (Experiment 1) and working memory (Experiment 2). In Experiment 1, a directed forgetting task was used. This task measures(More)
Formal thought disorder (FTD) has been associated with abnormalities in the semantic memory system. However, it is still unclear whether these abnormalities are related to the organization of the semantic system, or to the automatic spread of activation-inhibition in semantic networks. In this paper these alternative proposals are examined. Schizophrenic(More)
BACKGROUND Whereas deficits in executive functioning have been widely reported in schizophrenia and, somewhat less, in bipolar disorder, few studies have addressed this issue in people diagnosed with borderline personality disorder. Importantly, no studies to date have compared the ability to cope with interfering information in all three groups of(More)
Working Memory (WM) span predicts subjects' performance in control executive tasks and, in addition, it has been related to the capacity to inhibit irrelevant information. In this paper we investigate the role of WM span in two executive tasks focusing our attention on inhibitory components of both tasks. High and low span participants recalled targets(More)
We evaluated phonological and visuospatial working memory (WM) in autism spectrum disorders. Autistic children and typically developing children were compared. We used WM tasks that measured phonological and visuospatial WM up to the capacity limit of each children. Overall measures of WM did not show differences between autistic children and control(More)
seen (sensitivity– seen) and used (sensitivity–used). Participants also completed the spelling section of the Wide Range Achievement Test–3. Spelling scores were not significantly correlated with self-report measures of text messaging frequency, but there was a significant positive correlation between sensitivity–seen from the TAT and spelling scores. The(More)
Extrapyramidal symptoms (EPS) associated with antipsychotic medication can provoke severe discomfort and disability. Some instruments have been proposed to assess EPS, but they are not widely used in clinical settings. This paper aims to provide a translational tool for the detection of EPS: lacunarity of patients’ handwritings. Lacunarity is a measure,(More)
