Faster presentation rate most likely increases processing load, and these data suggest that WM performance in ADHD-IA males may be more influenced by processing speed demands than the ADHD-CT group.
Furthermore, we hypothesize that the genetic 'effect size' will increase with processing load reaching a peak or to asymptote around the capacity limit.
The distractor-related activation increases in the bilateral caudate heads, right IFG and left middle frontal gyrus (MFG) at low load probably reflect increased processing of sensory inputs and are consistent with the prediction of load theory that distractor interference is resolved at later stages of central processing at low load [8], [43].
This research demonstrated that WM tasks that selectively draw on resources involved in either the target (but not distractor) processing or vice versa led to increased processing of the stimulus that was not loaded (e.g., increased distractor processing when WM selectively loaded on target processing; Kim, Kim, & Chun, 2005; Park, Kim, & Chun, 2007).
It has been observed that there is a significant influence of mental load on micrographia 24 and increased processing demands within the writing task contribute to reduction in writing size.
Load theory asserts that task performance under these conditions results in increased processing of irrelevant distractors because of the reduced ability to actively maintain the stimulus-processing priorities of the main task while working memory is loaded in another task.
The defective Ca2+ load is caused by fragmentation of the mitochondrial network, due to increased processing of OPA1, which reduces the volume of individual organellar particles and disrupt the matrix continuity of the mitochondrial network.
Conditions of high WM load that reduce its availability to exert priority-based control over the task result in increased processing of irrelevant distractors (due to the reduced distinction between relevant and irrelevant information).
Thus, loading WM cognitive control functions with the requirement to actively maintain other stimuli (e.g., rehearse a random set of digits) impairs the ability to control attention in accordance with stimulus-processing priorities, leading to increased processing of irrelevant distractors (e.g., De Fockert, Rees, Frith, & Lavie, 2001; Lavie, 2000; Lavie & De Fockert, 2005; Lavie et al., 2004).
