What is the primary function of pheromones in nature, and how do they achieve this?

In nature, pheromones are primarily used to signal readiness to mate or danger nearby, and they achieve this by releasing chemical substances into the environment that trigger a behavioral or physiological response in other members of the same species. Signup and view all the answers

What were the two potential human pheromones investigated in the Zhou et al. (2014) study, and where are they typically found in humans?

The two potential human pheromones investigated were androstenedione (AND) and estratetraenol (EST), typically found in male semen and sweat, and female urine, respectively. Signup and view all the answers

How did the researchers in the Zhou et al. (2014) study expose participants to the potential pheromones, and what task were they asked to perform?

Participants were exposed to the smell of cloves with either AND, EST, or no added pheromone, and they were asked to determine the gender of stick figures walking on a screen. Signup and view all the answers

What is the controversy surrounding the role of pheromones in human behavior, and why is it a topic of ongoing research?

The controversy surrounds the lack of identified human pheromones, and ongoing research aims to investigate their potential role in influencing human behavior. Signup and view all the answers

How do cortisol levels and pheromones relate to human behavior, and what is the potential impact on physiological response to stress?

Cortisol levels can impact cognitive function and performance, while pheromones may influence behavior, particularly in relation to sexual behavior. Chronically elevated cortisol levels can also impact physiological response to stress, leading to potential long-term health consequences. Signup and view all the answers
