Combined factors effect of menstrual cycle and background noise on visual inspection task performance: a...

Area of Science:

• Cognitive Psychology
• Human Factors Engineering
• Women's Health

Background:

• The menstrual cycle and background noise are known to influence cognitive task performance.
• Previous research shows conflicting results regarding their individual effects.
• No studies have examined the combined impact of the menstrual cycle and background noise on task performance.

Purpose of the Study:

• To investigate the combined effects of menstrual cycle phase and background noise on visual inspection task performance.
• To analyze performance using Signal Detection Theory (SDT) metrics: sensitivity index (d') and response criteria index (beta).

Main Methods:

• Ten healthy female students with regular cycles participated.
• A VDT-based visual inspection task was employed.
• A 3x2 factorial design examined three menstrual phases (pre-menstruation, menstruation, post-menstruation) and two noise conditions (80 dB(A) noise, no noise).

Main Results:

• The sensitivity index (d') was significantly affected by both the menstrual cycle phase and the presence of background noise.
• No significant interaction (combinational effect) was found between the menstrual cycle and background noise on sensitivity (d').
• The response criteria index (beta) showed no significant effect across menstrual phases or noise conditions, although noise impacted individual decision-making tendencies.

Conclusions:

• Both menstrual cycle and background noise independently impact visual task sensitivity.
• The combined effect of menstrual cycle and background noise on visual inspection performance was not significant in this study.
• Background noise can influence individual response criteria in visual tasks, affecting decision-making tendencies.
