Three-Level Hypothesis of IM Effect
| Level | Processes | Narrative |
|---|---|---|
| Level I Primary* | Brain Clock & Temporal Processing | Increased temporal resolution (faster internal clock speed-faster rate of oscillation (faster processing speed) of the brain clock(s) improve neural efficiency of the brain (temporal g) |
| Level II Secondary* | Brain Network Communication & Synchronization This occurs because white matter tracts connected to • Prefrontal cortex • Right Parietal cortex • Supplementary motor area • Cerebellum • Basal ganglia (striatum) • Anterior insular • Cingulate cortices o Are strengthen through brain training exercises | Improved brain network(s) communication via increased speed and efficiency of through increasing the density of white matter tract processing, i.e., thicken glial cells particularly between bilateral parietal-frontal regions—P-FIT Model of Intelligence |
| Level III Tertiary* | Attentional Control System Comprise of following three subsystems: • Focus of Attention, • Working Memory & • Executive Functional Control | Improvement in efficiency of executive functions and working memory results in better complex cognitive processing and learning. |
