Clinical data of the sample are summarized in table 1. Comparing with baseline values, 9 patients (53%) showed a decreased PLF in post-session, while 8 patients (47%) presented a higher PLF (p =.759).
These data were recorded during testing and scored in post-session analyses using commercially available software (Activity Monitor 5.1, Med Associates).
Methodological studies of focus groups could include, for example, experimental studies that explore how focus groups influence participants' attitudes; studies where actual behaviour and behaviour as reported in focus groups is compared; or, as Hyde et al. (2005) suggest, studies where individual participants are asked in post-session questionnaires to validate the group discussion.
The individual analysis of CA-evoked improvement of two-point discrimination performance in the target group by means of Dunnett post-hoc tests revealed a significant reduction of thresholds of d1 in the post session (p = 0.007), of d2 in post (p ≤ 0.001) and rec-24 h session (p ≤ 0.001) and of d3, d4, d5 in post (p ≤ 0.001), rec-24 h (p ≤ 0.004), and rec-96 h sessions (p ≤ 0.010).
However, a corresponding congruency effect for familiar natural stimuli was only significant in the PRE fMRI session and just failed to reach significance in the POST session (t(17) = 2.027, P = 0.059).
This aimed at further supporting potential training-induced effects for artificial AV stimulation in the POST session.
Whereas in the post session CD listening period, RR subjects elicited the RR through audio instructions and HE subjects listened to another health education recording.
We were mainly interested in regions exhibiting a stable effect for the comparison of congruent and incongruent natural stimuli in both experimental sessions and, additionally, a novel, that is, training-induced effect of congruency for artificial AV stimuli only in the POST session.
Statistically, this would be most robustly reflected by a transition from a significant interaction of the factors material and congruency in the PRE session (due to congruency or incongruency effects only for the natural material) to a main effect of congruency in the POST session.
The latter was characterized by a significantly stronger response to trained artificial AV stimuli than to each of the unimodal (i.e., auditory and visual) conditions in the POST session (PRE: t(17) = 1.400, P = 0.17; POST: t(17) = 2.551, P < 0.05).
