Summary
The deviation effect, caused by irrelevant sounds capturing attention, was found in both serial-recall and mental-arithmetic tasks. This suggests the deviation effect is not specific to certain task requirements.
Area of Science:
- Cognitive Psychology
- Auditory Perception
Background:
- Irrelevant sound can disrupt visual tasks through changing-state and deviation effects.
- The deviation effect is thought to arise from attentional capture and be independent of task type.
Purpose of the Study:
- To investigate if the deviation effect is observed in both serial-recall and mental-arithmetic tasks.
- To address procedural factors that may have prevented the deviation effect in previous studies.
Main Methods:
- Modified procedural factors (e.g., in-person testing, blockwise sound presentation) from prior research.
- Compared the deviation effect in serial-recall and mental-arithmetic tasks under controlled conditions.
Main Results:
- Strong evidence for the deviation effect was found in both serial-recall and mental-arithmetic tasks.
- Results were consistent with studies demonstrating the deviation effect with specific procedural alignments.
Conclusions:
- The deviation effect is not task-specific.
- Procedural factors significantly influence the observation of the deviation effect in cognitive tasks.

The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
