These models may partly explain why we found higher right hemisphere activation for pictures than words (Table 1) even when concept and task were held constant.
Remarkably, we could accurately predict the position of an individual within this environment solely from the pattern of activity in his hippocampus even when visual input and task were held constant.
In different conditions of each experiment, different allocation instructions were used while the number of memoranda in each task was held constant.
The task was held constant and involved deciding if a visually presented stimulus referred to the same object as a simultaneously presented auditory stimulus.
Such mental activity requires that information about the topic or task is held as an active mental representation even if it is not currently conscious (see box labelled 'benign or task-related representation' in Fig. 1).
The EZ-diffusion model revealed that the drift rate increased (and, consequently, the decision boundary decreased) with MT. When the experimental task was held constant in our participants, MT corresponded to salutary changes in model parameters from NEMo representing the quality of memory items but not forgetting.
Third, we found that English normal readers had low LIFS activation relative to all other groups during perceptual as well as semantic tasks, even when the task and stimuli were held constant (i.e. perceptual decisions on non-objects) (Fig. 3).
It is for this reason that the OECD Survey of Adult Skills used frequencies for the response frames to task questions, since these were held to be less susceptible to cultural/cross-national bias than an "importance" scale.
"A task force was set up, meetings were held.
The first term on the right-hand-side equation is the extensive margin, i.e. the task importance is held constant (and represents the average task importance across the 2 years), and time variation relies on changes across occupations.
