Millisecond Forums

This is what I've done:
- Use only 3 sliders (negative activation, positive activation and arousal)
- Use only 3 Groups of Items (negative, positive and neutral)

This is what is giving me trouble:
- Show every slider on a different screen. So, every image should be displayed 3 times (one for each slider). On every repetition, the image should be followed by 1 of the 3 sliders.
- The same slider should not be used in more than 2 consecutive trials.
- The same Group of Items should not be used in more than 2 consecutive trials.

This is my code:

/group = 1
/pictureheight = 50%
/stimulusduration = 3000
/ITI = 0
/emotionprofile_instruction = "¿Cómo crees que se siente esta persona?"

<page intro>
Aquí empieza la segunda parte del experimento.

^^Primero necesitamos tomar algunas medidas de referencia para interpretar adecuadamente los datos. Por favor presiona la Barra Espaciadora para continuar y sigue las instrucciones.
</page>

<page tarea_experimental>
^^A continuación se mostrará una escena de una película seguida de fotos de diferentes personas. Se harán 3 preguntas diferentes acerca de cada foto.
^^Presiona la Barra Espaciadora para empezar
