Games description

The aim of the game is to practice (assess?) the player’s cognitive functions. It will consist of several games. We will try to implement the games as a single project developed by all of us in a git repository.

Game 1

The game is aimed at assessing visual and spatial short-term memory. It shows a board made of regular distributions of a even number of cards. Cards have different drawings. For each drawing, there are two identical cards. At the beginning the cards are flipped so you can’t see them. Users are allowed to flip 2 cards. If they match (have the same drawing), they disappear. Otherwise they are flipped. The game finishes when the player has found all the pairs, and therefore there are no cards left on the board. There is a limit of time to play the game. If the player finds the pair within the allotted time, the next level is shown, with more cards until the maximum level is reached and the game goes back to the screen menu.

Game 2

This will be a free version of the “One Card Learning Task”, a task of the Cogstate self-administered computerized neuropsychological battery. It aims at measuring visual learning and short-term memory. A series of cards is flipped over on the screen one at a time. For each card, the participant answers yes or not (pressing the corresponding buttons) to indicate if that card has been previously shown at any time during the task. Each correct answer gives 1 point. There is a maximum number of errors allowed. When the number of errors is reached, a new level starts with less allowed errors. When the maximum level is reached, the game returns to the main menu.

Game 3

This will be a free version of the “One Back Task” also from Cogstate and aimed at assessing and measuring attention and working memory. A series of playing cards is flipped over on the screen one at a time. For each card (starting from the second one), participants answer yes or not (pressing the corresponding buttons) to indicate if that card is the same as the previous one. Each correct answer gives 1 point. There is a maximum number of errors allowed. When the number of errors is reached, a new level starts with less allowed errors. When the maximum level is reached, the game returns to the main menu.

Game 4

Free test of categorization. A series of cards is flipped on the screen one at a time. Names of categories are shown below. For each card, the participant clicks on the corresponding category. Each correct answer gives 1 point. There is a maximum number of errors allowed. When the number of errors is reached, a new level starts with less allowed errors. When the maximum level is reached, the game returns to the main menu.

Game 5

Free test of executive functions. A series of cards showing a sequence of actions is shown. Participants must click on them in the proper order. If they succeed, the level is updated and a new sequence with more cards is shown until the last level is reached and the game returns to the screen level.

Game 6

Free test of attention. A series of pairs of cards are shown one after the other. For each pair, the user must say if they are the same or different. Each level is composed of a number of pairs, with approximatively the same level of difficulty. At each level the cards are more similar, and the time to answer is shorter.

Game 7

Free test of attention. A board made of tiny images (icons or similar is shown). The user must find the ones that are repeated a number of times (2, 3, 4 for instance). At each level, the number of stimuli (cards) increases. The stimuli themselves can have different levels of difficulty depending on their similarity.

Game 8

Free test of attention. A board made of tiny images (icons or similar is shown). The user must find the card that is similar to the one given in the shortest time as possible. For each game, there is a fixed number of stimuli to identify. At each level, the number of stimuli (cards) in the board increases. The stimuli themselves can have different levels of difficulty depending on their similarity.
