Expertise-based differences in search and option-generation strategies.

Abstract

The current work builds on option-generation research using experts of various skill levels in a realistic task. We extend previous findings that relate an athlete's performance strategy to generated options and subsequent choices in handball. In a 2-year longitudinal study, we present eye-tracking data to independently verify decision strategies previously inferred from patterns of generated options. A verbal protocol identified the option-generation process for each individual prior to an allocation decision. Although athletes of varying expertise generated the same number of options on average, these options differed in quality between expert, near-expert, and nonexpert athletes for both their initial and final choices. These and other key results are formalized to elaborate a model of option generation, deliberation, and selection.

Apathy in schizophrenia as a deficit in the generation of options for action.

“…A second line of research has been motivated by expert decision-making, such as in chess or sport situations (Klein, Wolf, Militello, & Zsambok, 1995;Raab & Johnson, 2007). However, only very few studies have used ill-structured everyday scenarios to study option generation (e.g., Hausser, Schlemmer, Kaiser, Kalis, & Mojzisch, 2014;Kaiser et al, 2013).…”

The effect of time constraint on anticipation, decision making, and option generation in complex and dynamic environments

“…Furthermore, the total number of response options generated was negatively related to final decision quality. These results were extended by Raab and Johnson (2007) when comparing the performance of 69 expert, near-expert, and non-expert handball players. Using the same optiongeneration procedure, higher-skilled handball players generated fewer options and selected final options that were of higher quality than did the less-skilled players.…”

“…They found a significant effect of time on quality of move, such that those moves deliberated for longer were better than those generated first (cf. Johnson & Raab, 2007). Furthermore, both skill groups benefitted from taking extra time to deliberate over a move (cf.…”

Does training with 3D videos improve decision-making in team invasion sports?

“…In a meta-analysis of 42 56 studies, Mann et al (2007) quantified the effect of experts having better decision-making 57 skills (e.g., picking up perceptual cues, visual search behaviours) compared to their lesser 58 skilled counterparts due to general training effects as a point-biserial correlation coefficient 59 (r pb ) of .31. Further, with a group of experts of various skill levels in handball, Raab and 60 Johnson (2007) provided longitudinal evidence that the first-option quality and choice time 61 of experts were better than those of their lesser skilled counterparts due to training effects. 62 The authors also showed that the visual search behaviour and therefore the acquisition of …”
