The following study was conducted to evaluate the effect of a game-based intervention in
the form of a card game, Blink, on selective attention for a sample of street youth in
Zambia, Africa. Based on previous research suggesting that selective attention and
executive functioning may be modified by game-based interventions in various
populations and contexts, this study sought to employ a card game intervention for
selective attention. The study was conducted with a repeated measures design, with a
paired sample within-groups t-test adapted from the TEA-Ch Sky Search measure of
selective attention, and the card game Blink as a selective attention intervention. The
participants (n = 8) showed a significant increase in selective attention skills after playing
Blink for a duration of roughly two weeks t(7) = -3.135, p = 0.016, d = 1.11, supporting
the research hypothesis that a game-based intervention can be a useful tool for improving
selective attention. The implication of the study was that it may be feasible to implement
further educational and cognitive interventions for the target population through costeffective
game-based interventions.
