What is a limitation of focusing on attention in cognitive psychology?

Focusing on attention in cognitive psychology has the limitation of an inability to multitask effectively. This limitation arises because when attention is concentrated on a specific task or stimulus, it can be challenging to allocate cognitive resources to multiple tasks simultaneously. Human cognitive processing has constraints, and when individuals attempt to focus on more than one task at a time, their performance on those tasks typically suffers. This phenomenon is known as task interference, where the demands of different tasks compete for limited attentional resources, leading to decreased efficiency and effectiveness in multitasking scenarios.

In this context, the other options highlight benefits rather than limitations. For instance, enhancement of memory recall, increased processing of information, and improved selective attention generally result from effectively harnessing attention. While attention plays a crucial role in these cognitive functions, the challenge of multitasking exemplifies a significant limitation when attention is overly focused.
