The type of the task, task difficulty (Appel, 1986), the goal of the task, the number of participants involved, task modality, the performance mode of the task, the amount of concern a participant feels about the consequence of the task, and the cultural experience of the participants are among these (McCafferty, 1992).
We used functional magnetic resonance imaging to investigate the effect of two factors on the neural control of temporal sequence performance: the modality in which the rhythms had been trained, and the modality of the pacing stimuli preceding performance.
To test differences in diagnostic performance between modalities for statistical significance, the relative DOR of one modality compared to another was calculated with its corresponding p value.
One series of 41 patients has been reported by Zemskova et al. but several imaging modalities were used, not in all patients, with intervals of several months, PET being performed as a second-line examination when others were not conclusive; so, performance of modalities cannot be compared [ 141].
Both groups showed consistent performance across modalities, as the executive demands of word and picture trials were broadly matched (Jefferies and Lambon Ralph, 2006).
FDG-PET was not performed due to the estimated low diagnostic performance of this modality for a diagnosis of p-GGN.
For each subtest, F tests were used to assess grey matter associations with performance for each modality (adjusting for the others) and conjointly across modalities.
According to the independent lexica account, final performance in one modality will not be influenced by the level of practice in the other modality.
Here we present the importance maps for animal/tool classification in all three modalities (pictures, spoken and written words), averaged over five subjects that showed highest classification performance in each modality (Figure 5).
