Effects of background noise and extraversion on reading comprehension performance.

Area of Science:

• Cognitive Psychology
• Environmental Psychology

Background:

• Acoustic distractions in the workplace can influence employee cognitive performance.
• Understanding the impact of different noise types on tasks like reading comprehension is crucial for productivity.

Purpose of the Study:

• To investigate the effects of various acoustic distractions (silence, white noise, sirens) on cognitive performance, specifically reading comprehension.
• To examine potential interactions between distraction levels and individual differences in extraversion.

Main Methods:

• A within-subject design was employed with 55 participants completing reading comprehension tasks under three auditory conditions: silence, white noise, and sirens.
• Cognitive performance was measured by task completion efficiency and accuracy.

Main Results:

• A significant main effect of background sound was observed, indicating poorer reading comprehension performance in the presence of noise.
• Sirens demonstrated the most substantial negative impact on performance, followed by white noise, compared to silence.
• No significant interaction was found between the type of acoustic distraction and participants' levels of extraversion.

Conclusions:

• Acoustic distractions, particularly sirens, significantly impair cognitive performance in reading comprehension tasks.
• The findings partially support previous research on distraction effects but do not align with Eysenckian theory regarding introverts and extraverts.
• The study highlights the need to consider the implications of workplace noise pollution on non-targeted individuals.
