While an elegant solution in theory, continuations can incur a significant memory load in practice, and may offer more navigation options than business requirements mandate.
Analysis of these data (anova– memory-load2 × training stage2 × entry8 × time-bin5 × S9) revealed a significant memory load × training stage interaction (F1,7=8.6, P=0.02).
A significant memory load × group interaction [ F 2,51) = 5.70, p = 0.006] indicated greater slowing in the 2-back condition relative to the 0-back for BD-I versus BD-II and HC.
Specialist practitioners highlighted that CFS/ME impacts not only on the 'big things' such as employment, but even on basic day-to-day leisure activities such as reading or watching TV, which need concentration and entail a significant memory load.
A significant interaction memory load × group [ F 2,51) = 5.43, p < 0.01] indicated the presence of group differences only during the 2-back condition, where subjects with BD-I showed lower accuracy than HC; no other pairwise comparison result was significant.
The factor run had no significant effect for accuracy and only showed a significant interaction with memory load for reaction time (RT) [ F 2,258) = 9.41, p < 0.001], indicating a decrease in RT for the 2-back condition only as the task progressed, although this effect did not differ across groups.
However, there was no significant effect of group [ F1,20 = 2.037, P = 0.17], and there was no significant interaction between memory load and group [ F1,23 = 0.770, P = 0.391].
In addition to complexity of the acquisition process, 3D face recognition involves significant memory requirements, and computational load while performing a one-to-many searching task as compared to the 2D counterparts.
There was a significant main effect of memory load [ F1,23 = 64.172, P < 0.001], with performance being significantly better on Load 2 trials [ d′ = 1.60] than on Load 4 trials [ d′ = 0.72].
Mean response times were 1-digit: 1686 ms, 2-digit: 1781 ms, 4-digit: 2020 ms. Repeated measures analysis of variance with subject as a random effect indicated a significant linear increase with memory load of 112 ms per digit (F1,13 = 20.99, P < 0.001).
The frequency distribution of significant power changes with memory load observed here fail to support a distinction between the theta and alpha bands as traditionally defined in scalp EEG studies, confirming the impression of the oscillatory peak-detection analysis, namely that task-modulated oscillations tend to occur in a broad range encompassing both of those bands.
