Mobile Switching Centers (MSCs) in wireless telecommunication networks must implement signaling overload controls to maintain acceptable performance during periods of high load especially due to fast changing hot spots resulting from user mobility. An MSC’s signaling load comprises a variety of service requests, some more important than the others, and it must treat them differentially under ov...

One account of the early versus late selection debate in attention proposes that perceptual load determines the locus of selection. Attention selects stimuli at a late processing level under low-load conditions but selects stimuli at an early level under high-load conditions. Despite the successes of perceptual load theory, a noncircular definition of perceptual load remains elusive. We investi...
