Registered outcomes 12
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | response inhibition | 8 weeks | Double Trouble (Cambridge Brain Science, n.d., p. 3) - "A variant on the Stroop task (Stroop, 1935). Three coloured words are displayed on the screen: one at the top and two at the bottom. Participants must indicate which of two coloured words at the bottom of the screen (ignoring the colour of those words) correctly describes the colour that the word at the top of the screen is written in" (p. 3). Participants have 90 seconds to solve as many problems as possible. The task is scored on the number of correctly answered problems minus the number of incorrectly answered problems. | ClinicalTrials.gov |
| Primary | attention | 8 weeks | Feature Match (Cambridge Brain Science, n.d., p. 4) - "Based on the classical feature search tasks that have been used to measure attentional processing (Treisman \& Gelade, 1980). Two grids are displayed on the screen, each containing an array of abstract shapes. In half of the trials the grids differ by just one shape. Participants must indicate whether or not the grid's contents are identical. Difficulty is increased or decreased by one shape depending on whether the participant got the previous trial correct" (p. 4). Participants have 90 seconds to solve as many problems as possible. The task is scored on the sum of the difficulties of all correctly answered problems minus the sum of the difficulties of all incorrectly answered problems. | ClinicalTrials.gov |
| Primary | verbal short-term memory | 8 weeks | Digit Span (Cambridge Brain Science, n.d., p. 4) - "A variant on the verbal working memory component of the WAIS-R (Weschler, 1981). A sequence of numbers will appear on the screen one after another. Once the sequence is complete, participants must repeat the sequence. Difficulty is increased or decreased by one number depending on whether the participant got the previous trial correct" (p. 4). After three errors, the task ends. The task is scored on the maximum level (e.g. the problem with the highest number of digits) that the participant successfully completed. | ClinicalTrials.gov |
| Primary | spatial short-term memory | 8 weeks | Spatial Span (Cambridge Brain Science, n.d., p. 6) - "A variant on the Corsi Block Tapping Task (Corsi, 1972). Sixteen squares are displayed in a 4 x 4 grid. A sub-set of the squares flash in a random sequence at a rate of 1 flash every 900 ms. Participants must repeat the sequence by clicking on the squares in the same order in which they flashed. Difficulty is increased or decreased by one square depending on whether the participant got the previous trial correct" (p. 6). After three errors, the task ends. The task is scored on the maximum level (e.g. the problem with the highest number of targets) that the participant successfully completed. | ClinicalTrials.gov |
| Primary | working memory | 8 weeks | Token Search (Cambridge Brain Science, n.d., p. 6) - "Based on a test that is used to measure strategy during search behaviours (Collins et al.,1998). Boxes are displayed in random locations. Participants must find a hidden "token" by clicking on the boxes one at a time. When the token is found, it is hidden within another box. The token will not appear within the same box twice, thus, participants must search the boxes until the token has been found once in each box. If they search the same empty box twice, or search a box in which the token has previously been found, this is an error and the trial ends. Difficulty is increased or decreased by one box depending on whether the participant got the previous trial correct" (p. 6). After three errors, the task will end. The task is scored on the maximum level (e.g. the problem with the most tokens) that the participant successfully completed. | ClinicalTrials.gov |
| Primary | visuospatial working memory | 8 weeks | Monkey Ladder (Cambridge Brain Science, n.d., p. 5) - "A variant on a task from the non-human primate literature (Inoue \& Matsuzawa, 2007). Sets of numbered squares are displayed on the screen at random locations. After a variable interval of time, the numbers disappear leaving just the blank squares and participants must respond by clicking the squares in ascending numerical sequence. Difficulty is increased or decreased by one numbered box depending on whether the participant got the previous trial correct" (p. 5). After three errors, the task ends. The task is scored on the maximum level (e.g. the problem with the highest number of boxes) that the participant successfully completed. | ClinicalTrials.gov |
| Primary | visuospatial rotations | 8 weeks | Rotations (Cambridge Brain Science, n.d., p. 6) - "Used for measuring the ability to manipulate objects spatially in mind (Silverman et al., 2000). Two grids of coloured squared are displayed to either side of the screen with one of the grids rotated by a multiple of 90 degrees. When rotated, the grids are either identical or differ by the position of just one square. Participants must indicate whether or not the grids are identical" (p. 6). Participants have 90 seconds to solve as many problems as possible. The task is scored on the sum of the difficulties of all correctly answered problems minus the sum of the difficulties of all incorrectly answered problems. | ClinicalTrials.gov |
| Primary | visuospatial processing | 8 weeks | Polygons (Cambridge Brain Science, n.d., p. 4) - "Based on the Interlocking Pentagons task (Folstein et al., 1975). A pair of overlapping polygons is displayed on one side of the screen. Participants must indicate whether a polygon displayed on the other side of the screen is identical to one of the interlocking polygons. Difficulty is increased by making the differences between the polygons more subtle or decreased by making the differences between the polygons more pronounced" (p. 4). Participants have 90 seconds to solve as many problems as possible. The task is scored on the sum of the difficulties of all correctly answered problems minus the sum of the difficulties of all incorrectly answered problems. | ClinicalTrials.gov |
| Primary | deductive reasoning | 8 weeks | Odd One Out (Cambridge Brain Science, n.d., p. 3) - "Based on a sub-set of problems from the Cattell Culture Fair Intelligence Task (Cattell, 1949). Nine patterns will appear on the screen. The features that make up the patterns are colour, shape, and number and are related to each other according to a set of rules. Participants must deduce the rules that relate the object features and select the pattern that do not correspond to those rules. Difficulty is increased or decreased depending on whether the participant got the previous trial correct" (p. 3). Participants have 3 minutes to solve as many problems as possible. The task is scored on the number of correctly answered problems minus the number of incorrectly answered problems. | ClinicalTrials.gov |
| Primary | verbal reasoning | 8 weeks | Grammatical (Cambridge Brain Science, n.d., p. 5) - "Based on Baddeley's three minute grammatical reasoning task (Baddeley, 1968). Short sentences describing the relationship of two shapes along with an image of the shapes are displayed on the screen. Participants must indicate whether the sentence correctly describes the pair of objects displayed on the screen" (p. 5). Participants have 90 seconds to solve as many problems as possible. The task is scored on the number of correctly answered problems minus the number of incorrectly answered problems. | ClinicalTrials.gov |
| Primary | planning | 8 weeks | Spatial Planning (Cambridge Brain Science, n.d., p. 7) - "A direct descendant of the 'Tower of London' planning task (Shallice, 1982). When the task begins, numbered beads are positioned on a tree-shaped frame. Participants must reposition the beads so they are configured in ascending numerical order, in as few moves as possible. Problems become progressively harder" (p. 7). Participants have three minutes to solve as many problems as possible. The task is scored by subtracting the total number of moves made from twice the minimum number of moves required. | ClinicalTrials.gov |
| Secondary | engagement | 8 weeks | The participants are given a Game Play Log on which they log daily the (1) minutes played, (2) minutes of study partner assistance provided, and (3) level achieved in the game. | ClinicalTrials.gov |
