What defines infradian rhythms in biological psychology?

• A. Rhythms that last less than 24 hours
• B. Bodily rhythms that last for more than 24 hours
• C. Rhythms that repeat every 24 hours
• D. Irregular bodily rhythms

Answer: (B)

In biological psychology, infradian rhythms are defined as bodily rhythms that have a cycle lasting more than 24 hours. These rhythms can encompass various physiological and behavioral processes, such as the menstrual cycle in humans or certain seasonal behaviors in animals. Since they extend beyond the typical daily cycle, they challenge our understanding of internal biological clocks, which typically align with circadian rhythms, those that repeat approximately every 24 hours. While other rhythms, like ultradian rhythms, are characterized by cycles shorter than 24 hours, the classification of infradian rhythms specifically emphasizes that these processes occur over an extended timeframe, making them an important aspect of biological rhythms and their influence on behavior and physiology.
