Hi,

I am currently using INQUISIT 4 Dot Probe Script, as per the online version provided by MacLeod et al (2007) paper. I am in the process of having to change the time parameters and affective word stimuli so that each participant is exposed to 3 different time durations (100ms, 500ms, 1250ms) of 3 x 64 pairs of differentially valanced words (i.e. 64 positive-neutral, 64 neutral-threat, 64 positive-threat), ideally in a randomized manner.

Thus, each participant would be presented with 192 trials of 3 different pairs of words, which are presented in 3 different time durations - would I be able to ask for your assistance regarding this matter please?

Would greatly appreciate your response. Thank you.
