Sensory processing in children with Autism Spectrum Disorder: Relationship with non-verbal IQ, autism severity and Attention Deficit/Hyperactivity Di…
2015
Abstract The main objective of this study was to analyze in a sample of children with ASD the relationship between sensory processing, social participation and praxis impairments and some of the child's characteristics, such as non-verbal IQ, severity of ASD symptoms and the number of ADHD symptoms (inattention and hyperactivity/impulsivity), both in the home and main-classroom environments. Participants were the parents and teachers of 41 children with ASD from 5 to 8 years old ( M = 6.09). They completed the Sensory Processing Measure (SPM) to evaluate sensory processing, social participation and praxis; the Gilliam Autism Rating Scale (GARS-2) to evaluate autism severity; and a set of i…
Childhood adaptation: Perception of the parenting style and the anxious‐depressive symptomatology
2020
Objectives Childhood adaptation is essential for proper social-emotional development. Children growing up in a family context where they feel supported and protected are less vulnerable in the presence of psychopathology. The aim of this study is analysing the impact of parenting styles and the anxious-depressive symptoms on child adaptation. Design and setting A total of 367 children between the ages of 10 and 12, following a similar distribution by sex. The children completed self-reports assessing parenting styles, child adaptation, and depressive-anxiety symptomatology. Methods The data were analysed using two complementary methodologies: linear regressions and fuzzy-set qualitative com…
Food-related sensory experience from birth through weaning: contrasted patterns in two nearby European regions
2007
International audience; This study describes infant feeding practices among mothers from two European regions from the perspective of early sensory experiences. Two groups of mothers, one in Dijon , France (n=139), the other in Aalen , Germany (n=157) with infants aged 4–9 months were interviewed using a structured questionnaire. Clear between- and within-group differences in weaning practices were found, particularly with respect to breastfeeding duration (Aalen>Dijon) and exposure to flavour variety early in weaning (Dijon>Aalen). By 4 months, 65% of infants in Dijon and 20% in Aalen, had received their first non-milk, solid foods. Before beginning to wean, 39% of mothers in Dijon offered…
Agreement in Asthmatics' Perception of Dyspnea During Acute and Chronic Obstruction
2005
Objective Three types of asthmatic patients can be identified during periods of clinical stability: “poor perceivers,” “normal perceivers,” and “over perceivers.” When asthmatics undergo bronchial challenge in the laboratory, the same distinctions in type of perception can be observed. The aim of the present study was to determine the level of agreement between the 2 situations. Patients and methods A total of 93 patients with persistent moderate asthma (36 men and 57 women; mean age 40 years) were studied. We asked them to assess their dyspnea on a modified Borg scale when stable and after each histamine dose in a bronchial provocation test. When a patient's Borg scale assessment in stable…
Persistent antinociception through repeated self-injury in patients with borderline personality disorder.
2012
Abstract Patients with borderline personality disorder, mostly female, exhibit severe autoaggressive behavior, namely an intentionally performed, nonsuicidal self-injury and severe blunting of pain perception, the mechanism of which is hitherto not understood. Because the nociceptive system displays a high degree of plasticity, the aim of this study was to analyze the relationship of pain perception to self-injurious behavior. Pain perception of mechanical and chemical noxious stimuli was studied by quantitative sensory testing in 22 patients (15 female, 7 male) with borderline personality disorder (BPD) according to DSM-IV and 22 age- and gender-matched controls. BPD patients exhibited a s…
Subjective Perception of Cognitive Deficit in Psychotic Patients
2006
The objective of this study is to evaluate the subjective perception of cognitive deficit and how it relates to the perception of patients' relatives. Differences between the subjective perception of cognitive deficits in 107 DSM-IV-diagnosed psychotic patients and that of their relatives or caregivers were evaluated using the GEOPTE Scale. Fair agreement was observed between patient and family perception of cognitive functions, although there were important differences on those items that correspond to social functioning. A high degree of correlation was detected between the scores on this scale and clinical global impression scores, as well as the physicians' global impression of cognitiv…
Self-persuasion on Facebook increases alcohol risk perception
2018
Contains fulltext : 198083.pdf (Publisher’s version ) (Closed access) In this experiment, we examined if participating in a Facebook group by generating antialcohol arguments (self-persuasion) is more effective than reading antialcohol posts of others (direct persuasion) in changing alcohol consumption, risk perception, and attitudes. In addition, it was examined if submitting posts moderated these effects. Participants logged into their Facebook account and joined a group that contained posts with antialcohol arguments. They either generated their own arguments with or without posting them, or read those present in the group with or without posting that they had read them. Next, participan…
Modulation of right motor cortex excitability without awareness following presentation of masked self-images.
2004
The neural substrates of self-awareness have been studied with a variety of neurophysiological and behavioral tools. In the present study, unconscious modulation of corticospinal excitability following presentation of self-images was probed with transcranial magnetic stimulation (TMS). TMS-induced motor evoked potentials (MEP) were collected from the contralateral first dorsal interosseus (FDI) muscle while subjects viewed masked pictures of their own face. MEP amplitudes were compared to those obtained when pictures of strangers were masked. Masked self-images induced a relative increase in corticospinal excitability when TMS was applied to the right primary motor cortex. These results dem…
Linguistic Bias Modulates Interpretation of Speech via Neural Delta-Band Oscillations.
2017
Language comprehension requires that single words be grouped into syntactic phrases, as words in sentences are too many to memorize individually. In speech, acoustic and syntactic grouping patterns mostly align. However, when ambiguous sentences allow for alternative grouping patterns, comprehenders may form phrases that contradict speech prosody. While delta-band oscillations are known to track prosody, we hypothesized that linguistic grouping bias can modulate the interpretational impact of speech prosody in ambiguous situations, which should surface in delta-band oscillations when grouping patterns chosen by comprehenders differ from those indicated by prosody. In our auditory electroenc…
Human walking along a curved path. II. Gait features and EMG patterns
2003
We recorded basic gait features and associated patterns of leg muscle activity, occurring during continuous body progression when humans walked along a curved trajectory, in order to gain insight into the nervous mechanisms underlying the control of the asymmetric movements of the two legs. The same rhythm was propagated to both legs, in spite of inner and outer strides diverging in length (P < 0.001). There was a phase lag in limb displacement between the inner and outer leg of 7% of the total cycle duration (P = 0.0001). Swing velocity was greater for outer than inner foot (P < 0.001). The duration of the stance phase diminished and increased in the outer and inner leg (P < 0.01), respect…
