Sentence examples for during the sampling trial from inspiring English sources

When the costs to obtain food in the baited arm in the radial-arm maze were increased (i.e., more effort needed to reach the reinforcer, by placing a rope in the way) during the sampling trial in the win-stay task, the number of errors made during choice trials significantly decreased, possibly because pigs paid more attention to the baited arm.

Importantly, exploration during the sample trial was not significantly different between the genotypes [time spent exploring objects (mean ± SEM): WT 56.7 ± 5.03 s, GluN1hypo 69.7 ± 6.80 s; F1,51 = 2.581, P = 0.114] and was not affected by sex (effect of sex F1,51 = 0.645, P = 0.426; genotype × sex interaction F1,51 = 1.421, P = 0.239).

After another delay, the subjects received a test trial identical to the second sample trial, except that two copies of the object from sample trial 1 ("old familiar" objects) and two copies of the object known from sample trial 2 ("recent familiar" objects) were present and one of the "old familiar" objects was shifted to a location in which it was not encountered during the sample trial 1.

An investigation ratio was calculated as: (exploration during the 5 min test trial)/(exploration during the 5 min test trial + exploration during the last 5 min of the sample trial).

First, the general experimental environment may have been less familiar to the rats during the first sample trial in x than during the second sample phase in y.

In subsequent test trials, both cylinders were present but the cylinder not present during the preceding sample trial was suspended over the platform and served as a cue for the location of the goal.

We may assume that the switched objects may have entered into association with the two adjacent, un-switched objects during the single sample trial or with extra-arena cues in the laboratory.

Finally, we recorded exploration during the two sample trials, to explicitly evaluate the possibility that this could have differentially biased exploration of the objects during the preexposure phase.

One aim of this experiment was to examine whether there was less total exploration during the first than the second sample trial; accordingly exploration during the two sample trials from each of the two test cycles was computed.

This measure yields ratios ranging between +1 and −1, with +1 representing exclusive exploration of the object that had not been presented in that context during its sample trial (the expected OIC result) and 0 representing equivalent exploration of the two objects.

The time that the mouse spent exploring the objects was recorded during both the sample and test trials.
