The role of anticipatory postural adjustments during whole body forward reaching movements
1998
THE purpose of this study was to examine the role of anticipatory postural adjustments (APAs) in the execution of forward oriented whole body reaching movements. From the standing position, eight healthy subjects were asked to reach an object placed at 45 cm from the feet, at both naturally paced and fast speeds. Electromyographic signals of six antagonistic muscles were analysed in conjunction with centre of mass (CM) displacements, centre of foot pressure displacements and resultant ground reaction forces. Results revealed that APAs created necessary angular momentum of body segments for effective task execution. These results suggest that APAs can initiate movements conducted from a fixe…
Effects of Training-Induced Fatigue on Pacing Patterns in 40-km Cycling Time Trials
2014
In some endurance sports, athletes complete several competitions within a short period, resulting in accumulated fatigue. It is unclear whether fatigued athletes choose the same pacing pattern (PP) as when they have recovered.This study aimed to analyze effects of fatigue on PP of cyclists during a 40-km time trial (TT).Twenty-three male cyclists (28.8 ± 7.6 yr) completed three 40-km TT on a cycle ergometer. TT were conducted before (TT1) and after (TT2) a 6-d training period. A third TT was carried out after 72 h of recovery (TT3). Training days consisted of two cycling sessions: mornings, 1 h at 95% of lactate threshold or 3 × 5 × 30 s all-out sprint; afternoons, 3 h at 80% individual ana…
Influence of Delay Period Duration on Inhibitory Processes for Response Preparation.
2015
In this study, we examined the dynamics of inhibitory preparatory processes, using a delayed response task in which a cue signaled a left or right index finger (Experiment 1) or hand (Experiment 2) movement in advance of an imperative signal. In Experiment 1, we varied the duration of the delay period (200, 500, and 900 ms). When transcranial magnetic stimulation (TMS) was applied 100 ms before the imperative, motor evoked potentials (MEPs) elicited in the first dorsal interosseous were strongly inhibited. For delays of 500 ms or longer, this inhibition was greater when the targeted muscle was selected compared with when it was not selected. In contrast, the magnitude of inhibition just aft…
FUNCTIONAL EFFECT OF SHORT-TERM IMMOBILIZATION: KINEMATIC CHANGES AND RECOVERY ON REACHING-TO-GRASP
2012
Abstract Although previous investigations agree in showing significant cortical modifications related to short-term limb immobilization, little is known about the functional changes induced by non-use. To address this issue, we studied the kinematic effect of 10 h of hand immobilization. In order to prevent any movement, right handed healthy participants wore on their dominant hand a soft bandage. They were requested to perform the same reaching-to-grasping task immediately after immobilization, 1 day before (baseline 1) and in other two following days without non-use (baseline 2 and baseline 3). While no differences were found among baseline conditions, an increase of the total duration of…
Elderly adults delay proprioceptive reweighting during the anticipation of collision avoidance when standing.
2012
The ability to reweight visual and proprioceptive information is critical for maintaining postural stability in a dynamic environment. In this study, we examined whether visual anticipation of collision avoidance (AV) while standing could facilitate the down-weighting of altered proprioception in young and elderly adults. Twelve young (24.91 ± 6.44 years) and 12 elderly (74.8 ± 6.42 years) participants stood upright for 180 s under two task conditions: (a) quiet stance (QS) and (b) standing while anticipating virtual objects to be avoided. In order to disrupt the accuracy of proprioceptive input participants were exposed to bilateral Achilles tendon vibration during the middle 60 s of stand…
Personalized Goal for Dyspnea and Clinical Response in Advanced Cancer Patients
2018
Abstract Background The clinical response after comprehensive symptom management is difficult to determine in terms of a clinically important difference. Moreover, therapies should try to reach the threshold perceived by the individual patient for the determination of a favorable response to a treatment. Measures The Edmonton Symptom Assessment Score (ESAS) was measured at admission (T0), and seven days after starting palliative care (T7). Patient Global Impression and Goal Response after one week of palliative care and its relation with the Personalized Dyspnea Goal were measured at T7. Intervention Patients admitted to palliative care units underwent a comprehensive symptom assessment by …
Prophecy and Apocalypse among the Oromo-Borana: The Power of Chiasmus
2018
This chapter bridges the rhetoric culture and anticipation theoretical domains for reinterpreting the prophetic and apocalyptic texts on the Oromo-Borana (Ethiopia). The analysis qualifies prophecy as a practice of anticipation, a rational and collective exercise of criticism to current social trends, facilitated by creative individuals that make full use of the cognitive potential of chiasmus and other rhetorical devises.
Hands-on or Video-based Learning with ANTicipation? A Comparative Approach to Identifying Student Motivation and Learning Enjoyment During a Lesson a…
2015
The observation of living animals in school laboratories provides authentic views of biological research. Various studies stress the importance of primary experiences in biology classes. However, educational films may serve as an alternative in some cases. The aim of this study was to investigate student motivation before and after treatments, including (1) an educational film, (2) a hands-on activity with living animals accompanied by an educational film and (3) a hands-on activity with living animals. We investigated the influence of teaching method, gender and class level on student motivation and learning enjoyment. In all treatments, Temnothorax ants were addressed, which can be easily…
The Case of Gabriel: A Linguistic Therapy of Evaluation Perspective
2010
This article describes the treatment of Gabriel, 24, an undergraduate student suffering from performance anxiety. His main symptoms were heart palpitations, aching muscles, inability to relax, nervousness, worry, and negative anticipation about performance in various classes. The treatment applied was 13 sessions of linguistic therapy of evaluation (LTE), a variety of cognitive therapy based on the theory of general semantics. The main therapeutic techniques involved emphasizing the difference between words and “facts” (the “map” and the “territory”), general semantics debate, and the focusing on orders of abstraction. Across treatment Gabriel showed a clear shift from an intensional orient…
Whatever next? Predictive brains, situated agents, and the future of cognitive science
2012
In the target article, Andy Clark addresses the question of how a probabilistic predictive coding model of the mind relates to our personal level mental lives. This question, he suggests, is “potentially the most important” (MS46). The question is important indeed, but Clark’s answer fails to capitalize on another possible advantage of this approach. Clark suggests that there is a disconnect between the way the world appears to us, on one hand, and the way that it is represented in the brain, on the other. He deals with this disconnect by limiting the scope of the theory, by pointing out that he is discussing a theory of how brains encode and process information, not a theory about how thin…
