Contextual information in situations of uncertainty: The value of explicit-information provision depends on expertise level, knowledge acquisition and prior-action congruency

Entscheidungsleistung und selbstgeneriertes Wissen zu Mustern in der Handballverteidigung: ein Fall von „representational redescription“

“…Experiment 1 refers to the data set gathered by (Magnaguagno et al, 2022) in their study on contextual information in situations of different degrees of uncertainty. Elite youth handball players were compared with near-elite youth handball players in a between-participant design.…”

“…Specifically, we present findings on the relationship between handball players' ability to explicitly detect a game-specific pattern and to initiate correct real-world motor responses in a 3:3 immersive defensive task. Previous research in team handball showed, on the one hand, a consensus on the superior decision making of more experienced players compared to less experienced players in adult (Magnaguagno & Hossner, 2020) and youth players (Hinz et al, 2022;Magnaguagno et al, 2022) and, on the other hand, a tendency that experts outperform their counterparts in pattern recall (Raab & Farrow, 2015) as well as pattern detection (Magnaguagno & Hossner, 2020). With respect to the latter, however, recent research on youth handball players revealed no relevant differences (Magnaguagno et al, 2022).…”

“…However, the development of such skills is considerably underresearched (Williams, Fawver, Broadbent, Murphy, & Ward, 2019). So far, investigations have focused on superior performance of skilled players compared to less-skilled counterparts for situational probabilities (Abernethy, Gill, Parks, & Packer, 2001;Farrow & Reid, 2012;Helm, Cañal-Bruland, Mann, Troje, & Munzert, 2020;Magnaguagno, Zahno, Kredel, & Hossner, 2022) and pattern identification-more precisely, pattern detection (Magnaguagno & Hossner, 2020), pattern recognition (North, Williams, Hodges, Ward, & Ericsson, 2009;North, Ward, Ericsson, & Williams, 2011;Roca, Ford, McRobert, & Williams, 2013;Vater, Luginbühl, & Magnaguagno, 2019;Williams, Hodges, North, & Barton, 2006), as well as pattern recall (Gorman, Abernethy, & Farrow, 2012North, Hope, & Williams, 2017;Raab & Farrow, 2015;Sherwood, Smith, & Masters, 2019;Smeeton, Ward, & Williams, 2004;van Maarseveen, Oudejans, & Savelsbergh, 2015). In contrast, the relevance of the intertwining between different perceptual-cognitive skills has received far less attention; even though it has been claimed that it is the interaction of these skills that facilitates decision making (Roca & Williams, 2016;Williams et al, 2017).…”

“…To extend the knowledge about the relationship between the aforementioned factors of decision making and pattern detection, we used data collected in two previously published studies on the impact of contextual priors on performance (Magnaguagno & Hossner, 2020;Magnaguagno et al, 2022). However, as we used the data sets to conduct fundamentally different analyses, the presented empirical results should be regarded as original data of randomized controlled trials.…”

“…Fifty-seven youth male handball players were recruited. This sample size resulted from the original study of (Magnaguagno et al, 2022), in which a statistical power analysis revealed an optimal total sample size of 60 participants. A post hoc analysis for an F-test and analysis of variance (ANOVA) design (i.e., main effects, within-between interaction) that was additionally conducted in G*power 3 (Faul, Erdfelder, Lang, & Buchner, 2007) with the input parameters [averaged f] = 0.42, α err prob = 0.05, N = 57, numerator df = 3, and number of groups = 4, revealed a power [1 -β err prob] of 0.73.…”
