[Solved] Describe the different methods employed by developmental researchers to measure behavioral changes across different ages. Internal Biological Factors: Intrinsic physical or physiological elements within the body that influence behavior, health, and development. Pornographic Movies: Films that display explicit sexual content with the intention of arousing the viewer, often subject to age restrictions and legal regulations. Sexual Coerced: Actions compelling someone into sexual acts without their consent through the use of force, manipulation, or threats, considered a form of sexual abuse. Habituation: Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulus, their interest wanes and they look away sooner.
