Dear fellow researchers,

I am currently designing cognitive tasks for non-human animals, and would like to hear your opinion on the randomization of stimuli.

In a first approach, the animals will receive two distinct visual cues to execute a certain behavior. I would like to already shuffle these visual cues, even though this is only' a pre-training condition.

In the final experiment, the animals will receive 2 different auditory cues to execute this behavior, these cues will also be randomized.

I have worked with randomized stimuli before, and used the traditional Gellermann (1933) series, as well as semi-randomized orders of stimuli.

What are, in your opinion, the pro's and con's of these attempts? Do you have suggestions, maybe even other than these approaches?

Thanks in advance,

all the best,

Diandra
