Visually produced locomotion in an autokinetic setup.
1987
On individual ttials, 15 subjects stood G m before a minicomputer screen displaying a colon in a completely darkened room Subjects were aware that the light source wzs stationary. They were instructed to fixate the colon and to perform nonlocomotive jogging in place for 2 min. and continuously to report their sensations. Room lights were turned on after 30 sec., and subjects' deviations from their starting places were measured. All subjects had moved toward the light source (M = 4.42 m, SD = .43) although they were convinced that they had not moved. Instead, they had reported either the light source approached them or the light source became larger and/or more intense. On a second trial, su…
Remote Photoplethysmography for Evaluation of Cutaneous Sensory Nerve Fiber Function
2021
About 2% of the world’s population suffers from small nerve fiber dysfunction, neuropathy, which can result in severe pain. This condition is caused by damage to the small nerve fibers and its assessment is challenging, due to the lack of simple and objective diagnostic techniques. The present study aimed to develop a contactless photoplethysmography system using simple instrumentation, for objective and non-invasive assessment of small cutaneous sensory nerve fiber function. The approach is based on the use of contactless photoplethysmography for the characterization of skin flowmotions and topical heating evoked vasomotor responses. The feasibility of the technique was evaluated on volunt…
Towards a pragma-linguistic framework for the study of sensationalism in news headlines
2013
This article sets out a framework for a language-oriented analysis of sensationalism in news media. Sensationalism is understood here as a discourse strategy of ‘packaging’ information in news headlines in such a way that news items are presented as more interesting, extraordinary and relevant than might be the case. Unlike previous content analyses of sensational coverage, this study demonstrates how sensationalism is instantiated through specific illocutions, semantic macrostructures, narrative formulas, evaluation parameters, and interpersonal and textual devices. Examples are drawn from a corpus of headlines of the ‘most read’ articles in the online outlet of the British mid-market tab…
Materialisme et linguistique chez Leopardi
1982
SUMMARYIn several of his letters Giacomo Leopardi (1798-1837), much better known as a poet and a man of letters than as a linguist, says that he is writing a book on the theory and history of language. Its title should have been Paralelo delle cinque lingue. As it happens, he did not write the book, but left a considerable number of notes in his intellectual diary, the Zibaldone, which he kept from 1817 to 1832. The paper investigates the relationship between Leopardi's linguistic theory and his materialistic philosophy. Leopardi, who was acquainted with the theories of Locke, Condillac, and Destutt de Tracy, envisaged the formation of words as an inseparable part of the formation of ideas …
Intelligence and Music: Lower Intelligent Quotient Is Associated With Higher Use of Music for Experiencing Strong Sensations
2020
Intelligence is a key psychological feature associated to emotion and perception. Listening to music is often linked to emotional experience and sensation seeking (SS), traits that have been shown overall negatively correlated with intelligence. In a sample of 53 musicians and 54 non-musicians, we assessed the use of music for experiencing strong emotions through the Music in Mood Regulation (MMR) and the intelligence quotient (IQ) by using the Wechsler Adult Intelligence Scale III (WAIS-III). We found a negative correlation between the full IQ score and the use of music for SS in both musician and non-musician groups. Furthermore, the use of music for SS was negatively correlated with Ver…
Altered postural control and stability in cirrhotic patients with minimal hepatic encephalopathy correlate with cognitive deficits
2017
Background & Aims: Cognitive dysfunction in cirrhotic patients with minimal hepatic encephalopathy (MHE) is associated with falls. Alterations in postural control and stability could contribute to increase falls risk in these patients. We aimed to assess whether postural control and direction-specific limits of stability are altered in cirrhotic patients with MHE compared to patients without MHE and controls. We also assessed if alterations in postural control correlate with neurological impairment and/or blood biomarkers. Methods: Posturography analysis, attention Stroop test and bimanual and visuo-motor coordination tests were performed in 18 controls, 19 patients with cirrhosis without M…
Temporal dominance of sensations and sensory profiling: A comparative study
2008
Abstract Temporal dominance of sensations (TDS) is a recent descriptive sensory method consisting in assessing repeatedly, until the sensations end, which sensation is dominant and in scoring its intensity. Compared to time–intensity, this method considers the multidimensionality of the perceptual space over time. The objectives of this study were first to compare description of gels containing different levels of odorants (peach and mint), citric acid, cooling agent and xanthan gum obtained with TDS and with a conventional descriptive method and then to explore the impact of mint and peach odorant on long lasting perception. TDS provided reliable information close to standard sensory profi…
Unwanted effects: Is there a negative side of meditation? A multicentre survey
2017
Objectives Despite the long-term use and evidence-based efficacy of meditation and mindfulness-based interventions, there is still a lack of data about the possible unwanted effects (UEs) of these practices. The aim of this study was to evaluate the occurrence of UEs among meditation practitioners, considering moderating factors such as the type, frequency, and lifetime duration of the meditation practices. Methods An online survey was developed and disseminated through several websites, such as Spanish-, English- and Portuguese-language scientific research portals related to mindfulness and meditation. After excluding people who did not answer the survey correctly or completely and those w…
Food memory and its relation with age and liking: An incidental learning experiment with children, young and elderly people
2008
International audience; The present study compared incidental learning and food memory in children, young adults and elderly people for three sensory modalities (taste, texture and aroma). The relation of gender and liker-status (i.e. how much we like a product) with food memory was also investigated. Participants received a complete meal including a custard dessert used as target under incidental learning conditions. 24 h later, participants were confronted with a series of samples consisting of the target and slightly modified versions of the target (distractors) and were unexpectedly asked to perform an ‘‘absolute memory’’ (‘‘Did you eat this sample yesterday?’’) and a ‘‘relative memory’…
Recollection in adolescents with Autism Spectrum Disorder.
2013
Abstract Introduction Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder primarily affecting social interaction and communication. Recently, there has been interest in whether people with ASD also show memory deficits as a result of abnormal brain development. However, at least in adolescents with ASD, the recollection component of episodic memory has rarely been explored. This paper is an evaluation of recollection in three different experiments in adolescents with ASD, using both objective (source discrimination) and subjective methods (Remember–Know judgments). Methods Three experiments were designed to measure different aspects of contextual information: sensory/perceptual …
