I would like to hear from fellow behavior analysts on massed trials and interspersed trials. Maybe I did not understand the concept well, so I will post here what I understand by each type of technique.

Massed trials: These are successive trials of the same task, usually presented in 3 blocks with 10 trials.

Interspersed trials: These are trials that are interspersed across multiple tasks, and multiple blocks are made between tasks to achieve 10 trials. That is, one of three trials of touch, then one or three of mand, then one or three of eye contact, and so on.

I usually use massed trials. From what I read in the last articles it is not clear which system gets the best results.

What is your opinion?
