Biomechanical analysis of anticipation of elite and inexperienced goalkeepers to distance shots in handball
2012
AbstractThe objective of this study was to evaluate the anticipation time and kinematic factors in the movement ofgoalkeepers’ center of mass when making a long-distance throw in handball. The sample group was composed of 14goalkeepers and field players. A force platform was used to measure the force of the goalkeepers’ reaction movements, whilethe throwers’ movements were recorded with high-speed cameras. The expert goalkeepers began to move 193 ± 67 ms beforethe ball was released, with a 67% success rate of interception. The inexperienced goalkeepers began their movement 209 ±127 ms with a 24% success rate. The time taken by expert goalkeepers to begin a vertical movement of their CM, rel…
No 'Honeymoon Phase' - Whose Health Benefits from Retirement and When
2017
I use a fixed effects instrumental variable approach to determine the effect retirement has on health. The exogenous variation in the probability to retire at the normal and early retirement age thresholds is exploited to instrument for the otherwise endogenous retirement decision. Six health aspects are considered: self-assessed health, depression, limitations in (instrumental) activities of daily living, mobility limitations, grip strength and number of words recalled. Using data for 10 countries from the Survey of Health, Retirement and Ageing in Europe (SHARE), I find that retiring both at the normal and early retirement eligibility ages significantly improves all health aspects, includ…
A Modern-Day Diary : Notes for Future Humans
2021
Abstract Time and being can be seen as a space. A modern-day diary is a way of exploring that space or state of being. Outlining and shaping it requires word, image and imagination. The question is framed cultural-philosophically, and the mode of writing is poetic essayism. Otherwise, the creative untangling and differentiation of the poetics of lived space is not possible. After all, the goal is to combine science and art and weave them into the same reflective fabric. The essential aspects include thoughts about the fullness and filling of something, about its fulfilment. Then the present moment is not seen as marking a boundary in just one direction: it is not just an endpoint of the pas…
An Architecture for Observational Learning
2014
In this thesis I present an architecture that learns new skills through observation and adapts to the environment through situated experience in the world. Such an architectural growth is bootstrapped from a minimal initial knowledge and the architecture itself is built around the biologically-inspired notion of internal models. The key idea, supported by findings in cognitive neuroscience, is that the same internal models used in overt goal-directed action execution can be covertly re-enacted in simulation to observe and understand the actions of others. The system applies these concepts to learning higher order cognitive functions like learning problem solving skills and social interactio…
Gender differences in French undergraduates' academic plans and wage expectations
2016
International audience; Gender differences in wage expectations may affect investment in human capital and increase inequalities in the labour market. Our research based on a survey of first-year students at a French university aims to focus on expectations at the beginning of the career. Our results show that anticipated earnings differ significantly between men and women. One year after graduation, we find a gender gap in pay of 16 percent. A wage decomposition method indicates that most of this effect is due to anticipation of discrimination. Ten years after graduation, anticipated discrimination is still almost as dominant in explaining the gender gap in pay. Finally, using a survey of …
Text type attribution modulates pre-stimulus alpha power in sentence reading
2021
Prior knowledge and context-specific expectations influence the perception of sensory events, e.g., speech, as well as complex higher-order cognitive operations like text reading. Here, we focused on pre-stimulus neural activity during sentence reading to examine text type-dependent attentional bias in anticipation of written stimuli, capitalizing on the functional relevance of brain oscillations in the alpha (8–12 Hz) frequency range. Two sex- and age-matched groups of participants (n = 24 each) read identical sentences on a screen at a fixed per-constituent presentation rate while their electroencephalogram was recorded; the groups were differentially instructed to read “sentences” (genre…
CSCL – a tool to motivate foreign language learners: The Finnish application
2003
This article discusses the applications of the theory of Computer Supported Collaborative Learning (CSCL) to teaching and learning a foreign language, in this case, one of the ‘Less Commonly Taught Languages’, Finnish. The ‘Virtually Finnish’ project was based on the idea of creating a larger, virtual Finnish learning community among the second-year Finnish language students in five US universities during the fall semester, 2001. CSCL was chosen as a base, as its principal goal is to aid the learners in sharing and distributing their knowledge to the whole learning community. In addition to discussing the set up and the content of the project, the students’ feedback about their language lea…
Orofacial reactivity to the sight and smell of food stimuli. Evidence for anticipatory liking related to food reward cues in overweight children.
2012
International audience; Whether food liking may be a risk factor of overconsumption and overweight/obesity remains a controversial issue. So far, most studies used subjective reports to assess consummatory behavior, approaches that might overlook subtle or implicit hedonic changes to sensory properties of foods. Therefore, we used a cue-exposure approach by recording different measures of hedonic processes (orofacial reactivity, self-rated pleasantness, food preference) in 6-11 years old overweight (n=20) and normal-weight (n=20) children. Children were exposed to the smell and sight of high and low-energy density food stimuli and to non-food stimuli during pre- and post-prandial states. Th…
Pattern analyses reveal separate experience-based fear memories in the human right Amygdala
2017
Learning fear via the experience of contingencies between a conditioned stimulus (CS) and an aversive unconditioned stimulus (US) is often assumed to be fundamentally different from learning fear via instructions. An open question is whether fear-related brain areas respond differently to experienced CS–US contingencies than to merely instructed CS–US contingencies. Here, we contrasted two experimental conditions where subjects were instructed to expect the same CS–US contingencies while only one condition was characterized by prior experience with the CS–US contingency. Using multivoxel pattern analysis of fMRI data, we found CS-related neural activation patterns in the right amygdala (but…
Auditory cortex reflects goal-directed movement but is not necessary for behavioral adaptation in sound-cued reward tracking
2020
Mounting evidence suggests that the role of sensory cortices in perceptual decision making goes beyond the mere representation of the discriminative stimuli and additionally involves the representation of nonsensory variables such as reward expectation. However, the relevance of these representations for behavior is not clear. To address this issue, we trained rats to discriminate sounds in a single-interval forced-choice task and then confronted the animals with unsignaled blockwise changes of reward probabilities. We found that unequal reward probabilities for the two choice options led to substantial shifts in response bias without concomitant reduction in stimulus discrimination. Althou…
