Clumsiness in Adolescence: Educational, Motor, and Social Outcomes of Motor Delay Detected at 5 Years

1994

This paper reports the follow-up at age 15 of a group of children who were diagnosed at age 5 as having delayed motor development. The group of children who were clumsy and the control group still differed in motor performance 10 years later: 46% of the members of the early motor delay group were classified as different from the control group on motor and perceptual tasks. The remainder made up an intermediate group that could not be clearly distinguished from the other groups. Adolescents with stable motor problems had fewer social hobbies and pastimes and had lower academic ambitions for their future than the controls, although the lower academic ambitions also reflect their lower academi…

Consistencies of psychomotor styles in interpersonal tasks

1975

Abstract.— Interpersonal behaviour of individuals in five tasks (individual performance, two dyadic tasks, two small-group tasks) was videotaped and coded on 11 psychomotor categories concerning (a) movements regulating interaction, (b) indications of tension, and (c) temperamental acts. The individual consistencies were examined on the basis of correlational analyses and task similarities. The consistency of individual psychomotor behaviour across all the tasks was highest in the number of selfinitiated acts (psychomotor activeness). Consistency was also found in the total tension score and the utilization of large/narrow space, while the effect of the particular tasks was clearly demonstr…

P 96. Prismatic lenses as a novel tool to directionally manipulate motor cortex excitability: Evidence from paired-pulse TMS

2013

Introduction Prismatic adaptation (PA) is a visuo-motor procedure requiring participants to adapt to prismatic lenses shifting the visual scene horizontally. Such an adaptation produces a phenomenon called “after-effect”, opposite to the side of lenses deviation. The after-effect has been frequently associated with a shift of spatial attention in the same direction and with a restoration of hemispatial neglect symptoms. PA has captured the interest of neuroscientists in the last decades, since it affects high-order spatial cognition even thought consisting of low-level visuo-motor processes. Objectives Despite a huge literature on this procedure, the basic neural processes related to PA and…

Complete locked-in and locked-in patients: Command following assessment and communication with vibro-tactile P300 and motor imagery brain-computer in…

2017

Many patients with locked-in syndrome (LIS) or complete locked-in syndrome (CLIS) also need brain-computer interface (BCI) platforms that do not rely on visual stimuli and are easy to use. We investigate command following and communication functions of mindBEAGLE with 9 LIS, 3 CLIS patients and three healthy controls. This tests were done with vibro-tactile stimulation with 2 or 3 stimulators (VT2 and VT3 mode) and with motor imagery (MI) paradigms. In VT2 the stimulators are fixed on the left and right wrist and the participant has the task to count the stimuli on the target hand in order to elicit a P300 response. In VT3 mode an additional stimulator is placed as a distractor on the shoul…

Psychotropic drugs and driving: prevalence and types

2013

Background Some psychotropic medications (e.g., benzodiazepines, sedative antidepressants, etc.) may impair cognitive and psychomotor functions and, therefore, endanger traffic safety (Ravera, Br J Clin Pharmacol, 72(3):505–513, 2011). They affect detection, registration, and information processing, problem solving, and decision-making processes, and they also affect emotional and social aspects. The objective of this research was to clarify three closely related issues that are significant for traffic safety: the prevalence of psychotropic drugs on driving, the most frequently used psychotropic drugs to treat depression, anxiety, insomnia, or any tranquilizers (whether it is a medical pres…

Extending existential feeling through sensory substitution

2023

AbstractIn current philosophy of mind, there is lively debate over whether emotions, moods, and other affects can extend to comprise elements beyond one’s organismic boundaries. At the same time, there has been growing interest in the nature and significance of so-called existential feelings, which, as the term suggests, are feelings of one’s overall being in the world. In this article, I bring these two strands of investigation together to ask: can the material underpinnings of existential feelings extend beyond one’s skull and skin? To begin, I introduce and adopt a componential-systemic view of extended affectivity. In doing so, I specify the vehicle externalist criteria for extension em…

Dielectric Spectroscopy of Recycled Polylactide

2014

The effects of multiple mechanical recycling on amorphous polylactide (PLA) were simulated by means of five successive injection-grinding cycles. The influence of the induced thermo-mechanical degradation on the dielectric properties of PLA was analysed. The relaxation spectra were studied in terms of the complex dielectric permittivity (ε0 and ε00) and the dielectric loss tangent, tg(d) in the frequency range from 102 to 107 Hz over the temperature interval from 0 C to 140 C. It was possible to distinguish two relaxations zones, one at low temperatures and high frequencies (b relaxation) and another at higher temperatures and lower frequencies (a relaxation). The individual relaxations wer…
