Clinical Trials

Tapping Test

The Speed Test REST-HECOOR exercise was inspired by the classic test of Fingertip tapping from the assessment battery NEPSY (Korkman et al., 1998). The test-taker is required to keep on clicking for 10 seconds and as rapidly as possible with the mouse, or finger if using a touch-screen device, in a defined area on the screen. Data is collected as the number of clicks during the allocated time, number of clicks inside the defined area and number of clicks outside it.

Psychomotor Vigilance Test

The Resolution Test REST-SPER was inspired by the classic paradigms Go/No Go Task (Gordon & Caramazza, 1982), Continuous Performance Test (Conners, 1989; Epstein et al., 2001), and the Psychomotor Vigilance Task (Dinges & Powell, 1985). The test-taker is required to rapidly press on circles which appear on the screen and to ignore hexagons should they also appear. Embedded in the task are 16 circles-only items and 8 circles-and-hexagons items. For each item data is collected on response time, response accuracy and cursor distance from target center.

Number-Size Congruency Test

The Processing Test REST-INH was inspired by the classic Stroop test (Stroop, 1935). The test-taker is required to press on the larger of two circles, regardless of the number inscribed in each circle, while ignoring the text that could appear on the top-middle part of the screen. They are then required to press on the higher number regardless of the size of the circle in which the number is inscribed.

Time Estimation Test

The Estimation Test EST-II is based on the Duration Pattern Test (DPT) (Frota & Pereira, 2003). The test-taker is asked to interrupt an ongoing auditory stimulus so as to reproduce the exact length of time of the previously presented one. In the first part of the task an animated drawing accompanies the stimulus. During the second part of the task, the drawing remains still.

Eye-Hand Coordination Test Fixed Trajectory and Predictable Direction

The Synchronization Test UPDA-SHIF is based on the Vienna Test System (VST) (Whiteside, 2002). In this task the test-taker is required to carefully and precisely track a ball which moves along a path. The distance in pixels between the center of the ball and the cursor moved by the user is considered to calculate the accuracy score.

Maze Test

The Programming Test VIPER-PLAN took as a reference the classic Porteus Maze Test (Porteus, 1950), and the Route finding (NEPSY) (Korkman et al., 1998). The test-taker is presented with several mazes with dead-ends and is required to successfully go through it, from start to end, in the smallest possible number of steps, and as fast as possible.

Stroop Test

The Equivalencies Test INH-REST was based on the classic Stroop test (Stroop, 1935). The test-taker is asked to press on the spacebar (go action) only if the color names on the screen are printed in the matching color and to refrain from pressing (no-go) if the color of the letters does not match the printed color name.

Eye-Hand Coordination Test Multidirectional and Unpredictable Direction

The Coordination Test HECOOR was inspired by the classic Trail Making Test (Reitan, 1955), and by the Vienna Test System (Whiteside, 2002). The test-taker is required to track, with the mouse (or on-screen digital joystick, if using a mobile device), a ball moving in an undetermined itinerary.

Visual Working Memory Span Test

The Concentration Test VISMEM-PLAN took as a reference the Corsi block-tapping test (Corsi, 1972; Kessels et al., 2000; Wechsler, 1945). In the first part of the task, some circles, within a fixed array of circles, light up. The test-taker is required to memorize which circles, within the array, have lit up and then try to reproduce the sequence in the right order. In the second part of the task, a delay of 4 secs is added between the first screen and the playback screen, in order to increase the time the user must retain the information.

Multimodal Lexical Memory Test

The Identification Test COM-NAM is based on the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). For each object shown, the test-taker must choose from three possibilities: 1) the item is presented for the first time in the task or 2) the last time it appeared the item was spoken or 3) the last time it appeared the item was presented as a picture.

Lexical Memory Test

The Inquiry Test REST-COM took as a reference the classic Boston Naming Test (Kaplan et al., 1983), the vocabulary test from WAIS-III (Wechsler, 1997), the Test of Variables of Attention (Greenberg et al., 1996), and the Rey Auditory Verbal Learning Test (Schmidt, 1994). A series of objects are shown. In a new series of objects, the test-taker must then recognize only those objects that were previously displayed. This new series could be presented as images or as spoken words.

Speed Estimation Test

The Estimation Test EST-I was inspired by the Biber Cognitive Estimation Test (Goldstein et al., 1996). In the first part, the test-taker is required to determine which of two balls moves faster. In the second part, another ball is added. In the third part, a fourth ball is added and it should be indicated which ball moves twice as fast as a designated ball (the red one). In the fourth part, while watching four balls moving in four separate itineraries, the test- -taker must determine as quickly as possible which ball will arrive at a given point first.

Divided Attention Test

The Simultaneity Test DIAT-SHIF stems from the classic Stroop test (Stroop, 1935), the Vienna Test System (Whiteside, 2002), and the Test of Variables of Attention (Greenberg et al., 1996). The test-taker is required to accurately follow a ball moving and turning in all directions on the screen while, at the same time, performing a variant of the Stroop test.
