Brief Summary

Hormonal fluctuations occur during the menstrual cycle and can affect cognition. For example, an increase in estrogen levels has been reported to temporarily enhance auditory perception of newly formed stimuli. It has been suggested that fluctuations in hormone levels can alter cognitive performance throughout the menstrual cycle because these fluctuations impact the neurobiology of the brain regions involved in cognition and emotion processing. Mental imagery (MI) refers to the mental process in which an individual imagines performing a movement without actually executing the movement. The effects of hormonal fluctuations on cognitive-perceptual skills have been mentioned above. In light of the above information, this study was planned to examine the relationship between menstrual symptom characteristics and mental imagery ability and to compare women s mental imagery abilities according to the phases of the menstrual cycle.

Conditions

Menstruation; Mental Imagery; Menstrual Cycles

Outcome Measures

Primary Outcomes (1)

• Motor Imagery Skill

  The Vividness of Movement Imagery Questionnaire-2 will be used to assess the vividness of participants' movement imagery ability. In the questionnaire, a total of 12 different actions are imagined, and the questionnaire has three subscales (Internal Visual Imagery, External Visual Imagery, and Kinesthetic Imagery). A 5-point Likert scale (1: Perfectly clear and vivid as a normal vision - 5: No image at all: Only know you are thinking of the movement) is used to score each action, and the total score for each subscale ranges from 1 to 60.

  In 1 month period

Secondary Outcomes (2)

• Menstrual Symptoms

  at baseline

• Menstrual Pain

Study Arms (1)

menstrual cycle monitoring group

Female students between 18-25 with regular menstrual cycles

Other: Since this was an observational study, no intervention was performed.

Interventions

Since this was an observational study, no intervention was performed. OTHER

Since it is an observational study, only evaluation will be made. Each participant s mental imagery ability will be evaluated with the Movement Imagery Vividness Questionnaire-2 four times, follicular phase, ovulation, luteal phase and menstrual phase. In addition, the pain intensity experienced during menstruation will be evaluated with the Numerical Classification Scale-11, and the symptoms experienced due to menstruation will be evaluated with the Menstruation Symptom Scale.
