What is the demographic profile of Andrade's participants in the study?

• A. Ages 18-55, mostly males
• B. 40 people, mostly females
• C. Ages 18 and 30, equal male and female
• D. Senior adults over 55

Answer: (B)

The demographic profile of Andrade's participants is characterized by a specific focus on a sample size and gender composition that is relevant to the study's aims. In option B, the mention of "40 people, mostly females" encompasses a manageable participant size often used in psychological research, allowing for a detailed analysis of the effects of doodling on various cognitive processes. Focusing on "mostly females" could suggest a targeted inquiry into responses or behaviors that might differ by gender, providing insights into how doodling may function in the context of demographic influences. The balance of sample size and gender highlights the importance of understanding how these factors might play a role in the outcomes observed in the study, which is central to the broader implications of the research findings regarding doodling and cognition.
