Although many types of scratch cards exist, research on gamblers’ physiological responses to scratch card wins, losses, and near misses has been limited to a single type of game. We created two distinct scratch card types. In a “Match Three” game, we expected arousal to rise with each successive matching symbol—hence arousal would change even before the final outcome was known. In a “Number Matching” game, where players were given a set of lucky numbers and hoped to find a match within a scratch-off play area, we expected arousal to rise only once a match was made. A near miss in a Match Three game involved uncovering two large-prize symbols (but not the third). A near miss in a Number Matching game involved just missing a match (lucky number 18, uncovering a 17). For each game type, participants played four cards (small win, near miss, and two losses) while their physiological arousal was recorded. Participants rated each outcome on a number of subjective measures. For wins, arousal changes occurred as predicted (pre-outcome changes for Match Three vs. only post-outcome changes for Number Matching games). Participants rated near-miss outcomes in both card types as being more subjectively arousing, disappointing, negative, frustrating, and urge inducing than for regular losses, but we found no strong evidence for physiological near-miss effects. We provide evidence that the structure of scratch card games influences the timing of individuals’ physiological responses to various outcomes. Resume Bien qu’il existe de nombreux modeles de cartes a gratter, les recherches menees jusqu’ici sur les reactions physiologiques des joueurs face a un gain, une perte ou un quasi-gain se limitent a un seul type de jeu. Nous avons concu deux jeux de cartes a gratter distincts. Le premier etait un jeu « a trois correspondances »; nous nous attendions a ce que le degre d’excitation monte a chaque apparition d’un symbole identique - et ce, avant meme que le resultat final soit connu. Le second jeu consistait a donner aux joueurs un jeu de chiffres chanceux avec instruction de devoiler un chiffre correspondant dans la partie a gratter de la carte; nous nous attendions a ce que l’excitation monte seulement apres le devoilement d’une correspondance. Dans le premier jeu, un quasi-gain consistait en la decouverte de deux symboles representant un lot important (mais pas du troisieme). Dans le second jeu, un quasi-gain consistait en l’obtention d’un nombre tres proche du chiffre gagnant (obtention d’un 17 alors que le gagnant est le 18). Les participants ont ete invites a gratter quatre cartes par jeu (un petit gain, un quasi-gain et deux pertes) tandis qu’on enregistrait leurs reactions physiologiques, puis a donner une evaluation subjective de chaque resultat. Les reactions anticipees se sont produites dans le cas des gains (soit avant le devoilement du resultat dans le premier jeu et seulement apres dans le second). Peu importe le type de carte, les sujets ont qualifie le quasi-gain, comparativement aux pertes regulieres, d’experience excitante, decevante, negative, frustrante et propre a attiser le desir de jouer, mais nous n’avons recueilli aucune preuve de reaction physiologique dans ce cas precis. Selon nos conclusions, la structure des jeux de cartes a gratter a une incidence sur le moment de la reaction physiologique aux differents resultats de jeu.
