Blackjack is a casino card game in which players attempt to build cards that total as close to 21 as possible without going over. The game is played with one or more decks of 52-cards and each card has a value of either 1 or 11 for face cards, or 10 for aces. Players are dealt two cards and may choose to stand (stop drawing cards), hit, split, or re-double their bets based on a set of rules. The dealer also gets two cards and must follow a set of rules for drawing additional cards.
After all players have placed their bets, the dealer will deal themselves two cards, one facing up and one facing down (the hole card). The dealer will then offer insurance to the players if they have an ace showing. Players may opt to take insurance for a bet equal to their original wager. If the dealer has a blackjack, they will pay the player for their original bet at a 2-1 payoff instead of the usual 3-2 payout on a blackjack.
The researchers also collected data on the blackjack plays of the participants and tracked their emotions during the game. They found that the higher a participant’s self-concept of confidence in their ability to play blackjack, the more they were likely to believe that their knowledge would lead them to positive outcomes in the game. They also found that when participants believed that they had a good understanding of basic strategy, they were less anxious and more likely to search for information on how to improve their hand-playing decisions.
