Este experimento consta de dos tipos de ensayos:

Los ensayos del primer tipo consisten en una serie de números del 1 al 20 rodeados cada uno por un círculo.
Su objetivo será unir con un trazo continuo los puntos en orden creciente,
tratando de evitar que los trazos se toquen.
Tendrá un límite de tiempo fijo para resolver cada ensayo.
AL COMENZAR CADA ENSAYO VERÁ UNA CRUZ EN EL CENTRO DE LA PANTALLA,
CUANDO ESTA DESAPAREZCA Y VEA LOS CIRCULOS DEBERÁ PRESIONAR EL BOTON IZQUIERDO DEL MOUSE (O SU PAD DE NOTEBOOK)
Y MANTENERLO PRESIONADO HASTA TERMINARLO.
No levante el dedo del botón al menos que hayas terminado el ensayo, o que este haya terminado por superar el tiempo límite.
El otro tipo de ensayo consiste en una serie de números del 1 al 10 y letras de la A a la J.
Su objetivo será unir con un trazo continuo los puntos de manera alternada (ejemplo 1-A-2-B-3-C, etc).


Su objetivo será realizar la tarea SIN PASAR POR ENCIMA DE SU PROPIO TRAZO y lo más rápido posible.
Los ensayos van a aparecer siempre alternadamente.

¡Suerte y muchas gracias por participar!
