Cognitive Games and Assessments

mindLAMP offers a variety of neurocognitive assessments in the form of games, which are native to the app. These will show up on the Assess page of the app, and performance scores can be displayed on the Prevent page.

Jewels​

Jewels replicates the Trail Making Tests, in which participants are asked to sequentially select numbered jewels in the correct ascending order.

The Trail Making Test, with its two subtypes A and B, typically used to screen for dementia and assess cognition. It evaluates visual and motor abilities, executive functioning, and set shifting (1). Evidence suggests that digital and computerized version of the pen-and-paper Trail Making Test reliably assess the same cognitive domains. (2, 3, 4). Trails A requires a patient to make a 'trail' connecting numbered circles, placed randomly on a single page, in ascending order. Trails B requires a patient to make a similar trail, but alternate between numbered and alphabetized circles.

mindLAMP offers its own digitized version of both version of the Trail Making Test, called Jewels. Here, the numbered circles are replaced by numbered jewels in both Jewels A and B. For Jewels B, instead of having alternating numbers and alphabets, the sets alternate between two differently shaped jewels. participants must select jewels starting from 1 in ascending order, within a given time limit. Participants are indicated which jewel shape they must begin at number 1 with. Here is an example of both Jewels A and B.

  1. Variant: Here, clinicians and researchers can define which Variant, A or B, they would like patients to play.
  2. Mode: The game can be played at four different difficulty modes - Beginner, Intermediate, Advanced, or Expert. Clinicians can customize which difficulty mode they would like patients to play, by selecting from the Mode category. a. Each mode varies by the Duration the player has to complete the trail. This can also be changed for each mode, by changing the various Durations, in seconds.
  3. Initial Diamond Count: This can be used to determine the number of jewels that appear at the Level 1, the maximum is 25.
  4. Initial Shape Count: If so desired, the game can present not 1 or 2 different shapes of jewels, as it would for Trails A and B respectively, but any number of shapes.
  5. Bonus points: As an additional gamification strategy, bonus points can be awarded for each level completed.

For more advanced settings, please contact our research team for assistance.

Scoring​

Scoring for both Jewels variants are out of a 100, with each incorrect jewel earning -2 point

Sample Instructions​

Sample Instructions, Jewels A: "Tap the jewels in chronological order, starting with number 1."

Sample Instructions, Jewels B: "Look at the bottom of the screen to see which jewel to collect first. Tap number of 1 of that shape, and then number 1 of the second shape. Continue alternating the jewel pattern in chronological order until all of the jewels have been collected."

Spatial Span​

Spatial Span is a task that assess visuospatial memory, derived from a computerized spatial span test, and iterating upon the commonly used Corsi Block Test and Wechsler Spatial Span tests (1). Spatial span assessments have been used in a variety of populations, including idividuals with autism, psychosis, and depression (2, 3, 4). In this game, white squares are arranged in a grid. Squares will 'light up' or change color to green, and then return to white, one square at a time. Participants are required to recall and reproduce the order in which squares in the grid light up. The task can be customized such that the patterns must be reproduced in the same order as cued, or in reverse of the order cued. At every subsequent level, the number of squares that light up increases.

The recall and reproduce task requires the visuospatial working memory. The backward variation also measures working memory, as some processing must be done before reproducing the pattern. Finally, the increasing number of squares to remember measures memory capacity.

Screen Shot 2021-08-23 at 3 30 50 PM

Sample Instructions​

Forward Spatial Span: "You will see a grid of boxes. The boxes in a grid will light up in a certain order. Remember that order, and then tap the boxes in the same order in which they lit up. Each level will have more boxes light up in the sequence. See how far you can get!"

Backwards Spatial Span: "You will see a grid of boxes. The boxes in a grid will light up in a certain order. Remember that order, and then tap the boxes in the REVERSE order in which they lit up. Each level will have more boxes light up in the sequence. See how far you can get!"

Spin the Wheel​

Spin the Wheel is based on the Iowa Gambling Task that aims to measure decision-making and risk-taking behavior (1). The Iowa Gambling Task has been effectively used in studying clinical conditions such as substance abuse, pathological gambling, and schizophrenia (2). The task has been effectively computerized, with no discernable difference between digital and analogue versions (2, 3). The game presents the user with a wheel that can be spun by selecting one of four buttons at the bottom of the screen. Each spin can result in a win or loss of money, and the total amount remaining is displayed at the top of the screen. Participants start with $2000 and have 20 spins per game by default.

Scoring​

Player score is represented by the amount of money held at the end of a 20 spin game.

Sample Instructions​

"The game presents you with two wheels that can be spun by selecting one of four buttons at the bottom of the screen. The colors of the buttons do not correspond to the colors on the wheel. Each spin can result in a win or loss of money, with the wheel at the top displaying the money you won and the bottom displaying the money lost. The total amount remaining is displayed at the top of the screen. You start with $2000 and have 20 spins per game by default. Points at the end of a session are represented in the amount of money you have."

Cats and Dogs​

Cats and Dogs is a digital task, originally developed for the assessment of early stage Parkinson's disease, which tests multiple domains at once: visual and working memory, attention, response control, and set-shifting (1). Users must remember the location of multiple stimuli, remember which stimuli to respond to and which to ignore, reproduce the location of the response stimuli from memory, and switch between which stimuli to pay attention to.

In this task, participants are first shown a pattern of boxes. The boxes temporarily lift, to reveal the image of a dog or a cat behind some of them. Participants are asked to select the boxes which a cat or dog behind them. At higher levels, participants must switch whether to respond to the the cat or the dog.

The cat and dog cues assess response control and set-shifting as go/no-go stimuli: participants must respond to one, but not the other, and then change which to respond to and which to ignore when instructed.

The animal stimuli and the box together assess visual memory, working memory, and attention: each cue is only briefly visible 'behind' the boxes, so participants must attend to the cues, remember the position of each stimulus, and then recall the position to select the correct boxes. They must also remember increasingly more cues at each subsequent trial within a level.

Sample Instructions​

"In this game, you will see a screen with many boxes. These boxes will 'lift', revealing either a dog, cat, or nothing behind them. Your task is to tap the correct boxes, based on what is behind each box. The instructions for which boxes are correct will change depending on the level, so pay attention to the animals!"

Pop the Bubbles​

Pop the Bubbles is a go/no-go task that can measure sustained attention and response control. Go/no-go tasks typically require a response to one stimulus, and response inhibition to another stimulus.

mindLAMP offers a task with multiple stimuli in the form of bubbles, which participants must 'pop' or ignore. Participants must pay attention the rules for each level to know which bubbles to pop and which to ignore. In addition to color-based responses, higher levels also demand pattern-based responses.

Customization​

The task can be customized by the clinician or researcher in the Activity settings, to adjust the speed at which each bubble is presented, the number of bubbles shown for a given level, and the duration between bubbles.

Screen Shot 2021-08-23 at 3 23 36 PM

Scoring​

Final scores on based on the percentage of bubbles successfully popped, the percentage of incorrectly missed bubbles, the percentage of correctly-ignored bubbles and the percentage of incorrectly popped bubbles, as shown below:

Pop Score (1)

Sample Instructions​

"In this game, you will see lots of different colored bubbles, one at a time. Your task is to "pop" the correctly colored bubbles, while ignoring the incorrect ones. Pay attention to the instructions for each level to know which colored bubbles you should tap, and which ones you should ignore. Your score is based on the percentage of balloons shown that you correctly tapped, minus the percentage of balloons shown that you incorrectly tapped, with a perfect score being 100%."

Balloon Risk​

Balloon Risk, or the Balloon Analog Risk Task (BART) is a computerized risk-reward assessment task (1). The BART has shown to be significantly correlated to self report scores on risk related constructs such as sensation seeking, impulsivity and behavioral constraint, as well as real world risk behaviors such as drug use, gambling, and sexually risky behavior (1, 2, 3). The Users must tap to inflate a balloon to the largest possible size without it bursting. The task has been successfully used as a computerized assessment for risk-taking behavior. Every time the participant taps the balloon their potential points will increase. Every time they hit β€˜collect points’, those points are added to the total. However, if the balloon is pumped too much, the balloon will pop. The number of points at which the balloon pops will change with each game.

Customizations​

Balloon Count: This will change the number of balloon trials required to complete the task.

Breakpoint Mean and Standard Deviation: The task can be customized to alter the mean number of taps required to burst the balloon, as well as the standard deviation for the number of taps required. These can be used to adjust the level of risk.

Screen Shot 2021-08-23 at 3 24 53 PM

Scoring​

Participants are given points based on the number of taps they made before they stopped inflating the balloon, or no points if the balloon burst.

Sample Instructions​

Tap the button to 'Pump Up Balloon' to inflate it as large as you can, before the balloon bursts. When you feel like you can't inflate it anymore without it bursting, tap the button to 'Collect Points'. The number of times you pumped up the balloon will be equal to the number of points you get. If the balloon bursts, you get no points!

Maze Task​

The Maze task can be used to measure motor control, and spatial problem solving. Though there is not a gold standard model, digital maze games have been utilized in the assessment of visual cognition and problem solving in individuals with neurodegenerative disorders, brain injury, and schizophrenia (1, 2, 3). Participants can tilt their phone to move the ball and exit the maze. The first level starts with one ball and two rings, and the difficulty increases with each level (more balls, more intricate puzzle designs).

Sample Instructions​

In this game, you can tilt your phone to control a small ball seen on your screen. Try to navigate the ball out of the center of the maze and into the open space. The faster you escape, the more points you will accrue.

Digit Symbol Substitution Test​

The symbol-digit substitution task has been used to evaluate motor speed, attention, associative thinking (1). Initially developed as part of the Wechsler Adult Intelligence Scale and later digitized, the task is one of the most frequently used assessment in neuropsychological testing (1, 2, 3). The measure has shown to be valid and sensitive to change in major depressive disorder, age related cognitive decline, alcoholism and a variety of other conditions (3). Participants are shown a series of symbols (greek letter). They are also shown a grid which maps various symbols to digits (digits shown are 1-9). For each successive symbol, participants are required to press the button containing the corresponding digit. Example: Participant is shown greek letter Ξ±. According to the map, Ξ± corresponds to "4". The participant then selects the "4" button.

Duration: The number of seconds the task will last

Scoring​

Participants are scored according to the total number of correct symbols pressed given the timeframe.

Sample Instructions​

In this game, you will be shown a symbol in the center of the screen. This symbol will correspond to a number. Check the symbol-mapping shown at the top of the screen and look for your symbol. Identify the symbol which corresponds to your symbol. Once you find the corresponding symbol, select the corresponding number at the bottom of the screen. After you make the correct selection, you will move on to a new symbol, and the process will repeat until time runs out. The faster you move, the more points you will accrue.
