Do goal cue and motor activity impact preschoolers’ working memory?

Fitamen, Christophe ; Blaye, Agnès ; Camos, Valérie

In: British Journal of Developmental Psychology, 2021, p. 1-16

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task...

The role of goal cueing in kindergarteners' working memory

Fitamen, Christophe ; Blaye, Agnès ; Camos, Valérie

In: Journal of Experimental Child Psychology, 2019, vol. 187, p. 1-16

Goal neglect has been shown to contribute to kindergarteners’ poor executive control. Hence, presenting goal cues during a task improves children’s performance in inhibition and switching tasks. The current study aimed at extending these findings to working memory (WM) by examining the extent to which kindergarteners’ poor WM performance can result from neglecting the goal to recall...

Biomechanical agreement between different imitation jumps and hill jumps in ski jumping

Ketterer, Jakob ; Gollhofer, Albert ; Lauber, Benedikt

In: Scandinavian Journal of Medicine & Science in Sports, 2020, p. sms.13834

Even though the take‐off in ski jumping is decisive, athletes only have a very limited number of training trials on the actual ski jump to practice under real ski jump conditions. Hence, various imitation jumps aiming to mimic the hill jump are performed during daily training. These imitation jumps should therefore mimic the kinematic pattern of hill jumps appropriately. This study aimed to...

Knowledge of results during vertical jump testing: an effective method to increase the performance but not the consistency of vertical jumps

García-Ramos, Amador ; Janicijevic, Danica ; Cobo-Font, Juande ; Marcos-Frutos, Daniel ; Fernandes, John F. T. ; Taube, Wolfgang ; Pérez-Castilla, Alejandro

In: Sports Biomechanics, 2020, vol. 0, no. 0, p. 1–13

This study aimed to determine whether the provision of jump height feedback (knowledge of result; KR) can increase the performance and the consistency of output variables. In a randomised order, sixteen participants performed six squat or countermovement jumps (three from a 90º knee angle and three from a self-preferred knee angle) with or without KR over four sessions. The provision of KR...

Acute alcohol intoxication and expectations reshape the spatiotemporal functional architecture of executive control

Ribordy Lambert, Farfalla ; Wicht, Corentin A. ; Mouthon, Michael ; Spierer, Lucas

In: NeuroImage, 2020, vol. 215, p. 116811

While the deleterious effects of acute ethyl alcohol intoxication on executive control are well-established, the underlying spatiotemporal brain mechanisms remain largely unresolved. In addition, since the effects of alcohol are noticeable to participants, isolating the effects of the substance from those related to expectations represents a major challenge. We addressed these issues using a...
