During probe trials the signal was presented as in regular trials but the responses of the animals were never reinforced, providing a partial reinforcement schedule for the mice.
This approach has been shown to be sensitive to variations and dynamics in conflict effects that are otherwise lost in regular trial-average scores (Ridderinkhof, 2002; van den Wildenberg et al., 2010).
First, it was possible that rats had learnt to react to the object views presented in generalization trials in a different way than in regular trials, given that, following a response, they had never received neither reward nor punishment.
To this aim, rat recognition of the transformed prototypes (i.e., those same object views that had been used as primes in the priming experiment) was explicitly tested, by presenting these conditions in regular trials and providing feedback to the animals about the correctness of their responses.
"In a regular trial in the civilian world," she said, "I have regular access to my client.
Although the statement is hearsay that might not be admissible in a regular trial, everyone knows, unless he shuts his eyes to the realities of life, that this is a relevant fact which, together with other circumstances, might indicate a factual probability that gambling is taking place.

While two of them did not finish the experiment, data of three participants were excluded because for them there was at least one of the experimental conditions in which no regular trial was left after screening (see Data Analysis for a description of the screening procedure).

"In fact, if Abu Omar had not been kidnapped, he would now be in prison, subject to a regular trial, and we would have probably identified his other accomplices". Spataro declined to comment on any specifics of the investigation because the case is pending in the Italian courts.
