Temporal metacognition: Direct readout or mental construct? The case of introspective reaction time.
J Exp Psychol Gen

Deciphering whether and which mental processes are accessible for metacognitive judgments is a key question to understand higher cognitive functions. Paralleling the crucial role of reaction times (RT) for unraveling the temporal sequence of mental processes, a comparable chronometric approach can be employed at the second-order level through introspective reaction times (iRT) measures. Although mean iRT correlate with mean RT, suggesting good metacognitive abilities, this would not necessarily imply a direct readout of the duration of the underlying processes as participants may instead rely on inferences based on other salient, nontemporal, cues.

Myoelectric control has emerged as a promising approach for a wide range of applications, including controlling limb prosthetics, teleoperating robots and enabling immersive interactions in the Metaverse. However, the accuracy and robustness of myoelectric control systems are often affected by various factors, including muscle fatigue, perspiration, drifts in electrode positions and changes in arm position. The latter has received less attention despite its significant impact on signal quality and decoding accuracy.

The forearm muscles coordinately control wrist motion, and their activity is affected by forearm rotation. Although forearm rotation has been implicated in the development of lateral and medial epicondylitis, its biomechanical background remains unknown. Therefore, the present study investigated the activity of wrist muscles in various forearm positions.

The purpose of this investigation was to examine muscle excitation at maximal running capacity without blood flow restriction (BFR) relative to submaximal running bouts with BFR. Fourteen college-aged males randomly completed four, three-minute running bouts at 70, 80, and 90% of peak speed with BFR (70%, 80%, and 90%) and without BFR at 100% of their peak speed (100%). The surface electromyographic amplitudes of the vastus lateralis, rectus femoris, and vastus medialis muscles were assessed.

Walking patterns can differ between children and adults, both kinematically and kinetically. However, the detailed nature of the ankle pattern has not been clarified. We investigated musculature, biomechanics, and muscle activation strategies and their relevance to walking performance in preschool (PS) and school children (SC), with adults (AD) as reference.
