______________ and ______________ are bottom-up factors that can influence multisensory integration, whilst ______________ and ______________ are top-down factors that can influence multisensory integration.

Question

BlackTom AI · Accepted Answer

In multisensory integration, bottom-up factors are typically driven by the sensory inputs themselves, while top-down factors are guided by higher-level cognitive processes.
Option 1: 'Context; spatial coincidence; expectation; temporal coincidence' places context and expectation in the bottom-up half and swaps temporal/spatial cues, which misclassifies context and expectation as bottom-up factors. This misalignment goes against the general idea that context and expectation are influenced by higher-level processing.
Option 2: 'Temporal coincidence; expectation; context; spatial coincidence;' assigns temporal coincidence correctly as bottom-up, but labels expectation as bottom-up and context as bottom-up as well, which is incorrect because expectation and context are typically viewed as top-down influences. The pairing here mixes the hierarchy and misattributes top-down roles.
Option 3: 'Temporal coincidence; spatial coincidence; context; expectation' correctly identifies the two bottom-up factors as temporal coincidence (the alignment in time between signals) and spatial coincidence (the alignment in space), while the two top-down factors are context (the surrounding information or situation) and expectation (predicted or anticipated input), aligning with established distinctions between bottom-up versus top-down influences.
Option 4: 'Context; expectation; temporal coincidence; spatial coincidence' places context and expectation in the bottom-up position and temporal/spatial coincidence in the top-down position, which reverses the conventional roles and leads to a conceptual mismatch about how sensory-driven vs. cognitive-guided influences operate in multisensory integration.
Thus, analyzing each option shows that only Option 3 preserves the correct separation between bottom-up and top-down factors, with the appropriate items assigned to each category.
