Concept of an extracellular regulation of muscular metabolic rate during heavy exercise in humans by psychophysiological feedback.
1996
Efferent motor signals to skeletal muscles concern not only the space/ time pattern of motion, but also the setting of muscular performance and through this the control of the current metabolic rate. For an optimal adjustment of metabolic rate during heavy exercise-e.g. in athletic competitions-a feedback control system must exist, including a programmer that takes into consideration a finishing point (teleoanticipation). The presented experiments, using Borg's scale, indicate the existence and functioning of a system for optimal adjustment of performance during heavy exercise and the relevance of teleoanticipatory effects. Thus motor learning includes not only somatosensory control, but al…
Effects of assisted training with neurofeedback on EEG measures, executive function and mood in a healthy sample
2015
The training in neurofeedback (NF) consists of teaching individuals to modify, adjust and enhance their brain activity pattern. The aim of our research was to evaluate the effect of training on cognitive processes, specifically executive function, and mood in a non-clinical sample. A sample of 30 female college students were assigned to three groups: RH: right hemisphere (n = 10), LH: left hemisphere (n = 10) and control (n = 10). The dominance pattern of beta and the inhibition of the theta pattern were trained in a single session. Measures of executive function (Iowa Gambling Test) and questionnaires of mood were taken pre and post training. We found that NF training produced significant …
Communicating through ancillary gestures: Exploring effects on coperformers and audiences
2020
Musicians make elaborate movements while performing, often using gestures that might seem extraneous. To explore these movements, we motion-captured and audio-recorded different pairings of clarinetists and pianists performing Brahms’ Clarinet Sonata No. 1 with two manipulations: (a) allowing the performers full vs. no visual feedback, and (b) allowing the performers full vs. partial auditory feedback (i.e., the clarinetist could not hear the pianist). We found that observer ratings of audio–visual point-light renditions discriminated between manipulations and refined this insight through subsequent audio-alone and visual-alone experiments, providing an understanding of each modality’s cont…
Mental fatigue induced by prolonged self-regulation does not exacerbate central fatigue during subsequent whole-body endurance exercise
2015
International audience; It has been shown that the mental fatigue induced by prolonged self-regulation increases perception of effort and reduces performance during subsequent endurance exercise. However, the physiological mechanisms underlying these negative effects of mental fatigue are unclear. The primary aim of this study was to test the hypothesis that mental fatigue exacerbates central fatigue induced by whole-body endurance exercise. Twelve subjects performed 30 min of either an incongruent Stroop task to induce a condition of mental fatigue or a congruent Stroop task (control condition) in a random and counterbalanced order. Both cognitive tasks (CTs) were followed by a whole-body …

Thermal noise limit for ultra-high vacuum noncontact atomic force microscopy
2013
The noise of the frequency-shift signal Δf in noncontact atomic force microscopy (NC-AFM) consists of cantilever thermal noise, tip–surface-interaction noise and instrumental noise from the detection and signal processing systems. We investigate how the displacement-noise spectral density dz at the input of the frequency demodulator propagates to the frequency-shift-noise spectral density dΔf at the demodulator output in dependence of cantilever properties and settings of the signal processing electronics in the limit of a negligible tip–surface interaction and a measurement under ultrahigh-vacuum conditions. For a quantification of the noise figures, we calibrate the cantilever displacemen…
#How Can We Help You?: An Instagram-Based Online Self-Help for Eating Disorders
2023
In recent years, there has been a noticeable increase in online self-help treatments and peer-support programs for eating disorders. The possibility of easily accessing them anytime makes these programs an important support tool and an influencing source for increasing motivation to change. The aim of this work is to describe the #How can we help you? project, its initial feedback received from users, and its future directions. Researchers and clinicians developed an Instagram profile (Dicci Come Aiutarti) based on psychoeducation, aimed at orienting those suffering from a self-reported eating disorder towards clinical care, providing information about eating concerns and related constructs…
(Dis)empowering assessment? : assessment as experienced by students in their upper secondary school EFL studies
2017
Assessment has a great deal of power over students. However, there is little research on how students experience assessment and its power in the school context. The purpose of this mixed-methods study is therefore to examine how students in one Finnish upper secondary school experienced assessment and (dis)empowerment in their EFL studies. The present study, which situates itself within the realm of teacher research, also aims to experiment with alternative assessment methods in order to investigate whether they could foster empowerment in upper secondary EFL studies. The study comprises five articles and a monograph, and is divided into two parts, each with its own research aims. Part 1 an…
Analysing students’rating of the SLP Digitally Competent Educators
2021
This article uses student feedback to examine the perspective of participants in the short learning programme (SLP) pilot Digitally Competent Educators (DCE). This SLP was targeted at the continuous professional development and lifelong learning for educators at various levels and several education areas. Student feedback was collected in 2020 using anonymous surveys at the end of each course. This implies that respondents were those participants who completed the course. Feedback, used on further development of the SLP, focused on the content and implementation of the course modules. The SLP followed the design guidelines produced inside the E-SLP project and was based on the Digital Compe…
Good job! - giving positive feedback in EFL lessons : comparison of primary and secondary school
2013
Tämän tutkimuksen tarkoituksena on selvittää, miten positiivista palautetta annetaan ala- ja yläkoulussa ja vertailla näitä kahta kouluastetta. Tutkimuksen lähtökohtana on, että alakoululaiset saavat positiivista palautetta enemmän kuin yläkoululaiset. Yksi keskeisistä kohteista on vertailla, kuinka opettajien ja oppilaiden näkemykset positiivisesta palautteesta kohtaavat. Lisäksi tarkoituksena on selvittää, mistä asioista oppilaat saavat palautetta. Kiinnostuksen kohteena ovat myös palautteenantotavat sekä positiivisen palautteen määrä. Tutkimus on luonteeltaan laadullinen. Tutkimukseen osallistui yksi englanninopettaja ja neljä hänen oppilastaan alakoulusta sekä yksi englanninopettaja ja …
