Description: The current study aims to systematically assess the impact of sequential losing and winning streaks on behavioural markers of within-session chasing (persistence, change in stake amount and speed of play) in a large-scale dataset of >4000 players (with ~71 million bets) in a popular dice gamble called Mystery Arena. Chen et al. (2022) assessed within-session chasing across these facets in the same gambling product, albeit in a smaller dataset (>2500 players with ~10 million bets). They found that players overall were more likely to stop playing and decreased their stake amount after losses than wins, but played more quickly following losses than wins. However, this study assessed within-session chasing as a function of prior losses/wins, without taking streaks into account. The current project aims to investigate if the findings from Chen et al. (2022) can be replicated in a larger dataset, and extend it by examining how these behavioural makers may change as a function of winning and losing streaks. We split the entire dataset into an exploratory dataset (consisting of ~25% of the total dataset) and confirmatory dataset (~75% of the total dataset). In the current pre-registration, we are pre-registering the analysis plan and the expected results for the confirmatory study based on the exploratory dataset analyses.
