Abstract Objectives: The study’s aim was threefold: examine 1) the relation between executive functions and coach-rated evaluation of game intelligence; 2) the predictive value of cognitive and athletic performance parameters concerning playing time, and 3) injuries to analyze fundamental associations of soccer expertise across all ages.Design/Methods: A sample of 172 elite soccer players (12-34 years of age) performed tests assessing multiple-object tracking, working memory capacity, cognitive flexibility, and inhibition. Endurance-performance at the individual anaerobic threshold (IAT), ability to repeatedly perform intense exercises (RIEA) and maximal anaerobic performance parameters (squat jump, countermovement jump, drop jump, sprint) were also measured. Game intelligence game time and injury incidence were tracked.Results: Working memory capacity, cognitive flexibility, and a total cognition score showed correlations with game intelligence, and the same parameter, along with selective attention and game intelligence, were also correlated with game time. Sprint and RIEA were connected with game time, whereas contact injuries only correlated with sprint, and noncontact injuries with sprint and performance-IAT.Conclusion: Especially executive functions represent fundamental associations with game intelligence and game time across all age groups but not with injury incidences, whereas certain physiological abilities may contribute to more game time and less non-contact injuries depending on age.

Functional Near Infrared Spectroscopy

This study explored the differentiated neural correlates of mental rotation (MR) in preschoolers with high and low working memory capacity using functional near-infrared spectroscopy (fNIRS). Altogether 38 Chinese preschoolers (M = 5.0 years, SD = 0.69 years) completed the Working Memory Capacity (WMC) test, the Mental Rotation (MR), and its Control tasks (without MR). They were divided into High-WMC (N1 = 9) and Low-WMC (N2 = 18) groups based on the WMC scores. The behavioral and fNIRS results indicated that: (1) there were no significant differences in MR task performance between the High-WMC (Mmr = 23.44, SD = 0.88) and Low-WMC group (Mmr = 23.67, SD = 0.59); (2) the Low-WMC group activated BA6, BA8, BA 9, and BA 44, whereas the High-WMC group activated BA8, BA10 and BA 44 during mental rotation; (3) significant differences were found in the activation of BA44 and BA9 between the High-WMC and Low-WMC groups during mental rotation; and (4) the High-WMC and Low-WMC groups differed significantly in the activation of BA 9 and BA10 during the control tasks, indicating that both areas might be responsible for the group differences in working memory.

Abstract. Although attention control accounts for a unique portion of the variance in working memory capacity (WMC), the way in which attention control contributes to WMC has not been thoroughly specified. The current work focused on fractionating attention control into distinctly different executive processes and examined to what extent key processes of attention control including updating, shifting, and prepotent response inhibition were related to WMC and whether these relations were different. A number of 216 university students completed experimental tasks of attention control and two measures of WMC. Latent variable analyses were employed for separating and modeling each process and their effects on WMC. The results showed that both the accuracy of updating and shifting were substantially related to WMC while the link from the accuracy of inhibition to WMC was insignificant; on the other hand, only the speed of shifting had a moderate effect on WMC while neither the speed of updating nor the speed of inhibition showed significant effect on WMC. The results suggest that these key processes of attention control exhibit differential effects on individual differences in WMC. The approach that combined experimental manipulations and statistical modeling constitutes a promising way of investigating cognitive processes.

Abstract. The Monty Hall Dilemma (MHD) is an intriguing example of the discrepancy between people’s intuitions and normative reasoning. This study examines whether the notorious difficulty of the MHD is associated with limitations in working memory resources. Experiment 1 and 2 examined the link between MHD reasoning and working memory capacity. Experiment 3 tested the role of working memory experimentally by burdening the executive resources with a secondary task. Results showed that participants who solved the MHD correctly had a significantly higher working memory capacity than erroneous responders. Correct responding also decreased under secondary task load. Findings indicate that working memory capacity plays a key role in overcoming salient intuitions and selecting the correct switching response during MHD reasoning.
