They live under difficulty conditions …….. do not help them to develop their human potential.
This task, containing difficulty conditions for the Nogo stimuli, enabled the acquisition of aware errors (mainly in the easy and intermediate conditions) and unaware errors (in the difficult condition), in addition to hits (i.e. correct responses on Go trials).
Participants underwent adaptive training in the n-back working memory task over 12 sessions under increasing difficulty conditions.
As such, when fitting the DDM to the data, we allowed the boundary separation and nondecision time to fluctuate across the speed and accuracy conditions, whereas drift rate was allowed to vary across difficulty conditions.
One-sample t tests using the D2 Index revealed that both groups of rats had a consistent preference for the novel objects during the sample phases for all three recency difficulty levels (i.e., a total of six standard recognition phases, two for each of the three difficulty conditions for the Sham and the ATNx groups; all ps <.001).
In the high-difficulty condition, the items were masked by visual noise (high encoding load), while in the low-difficulty condition, the items were presented without visual noise.
Auditory deviants produced the typical impairment to performance in the low-difficulty condition, but when the visually presented items were difficult to perceive, a sound with deviating elements produced no more disruption than a sound without deviating elements (Fig. 2).
For the N-back, we first conducted a repeated-measures analysis of variance (ANOVA), with difficulty (back condition) as the within-subjects factor and drug and genotype as the between-subjects factors.
