Answer :
Final answer:
The IQ of an average 18-year-old today is likely higher than her counterpart 60 years ago due to the Flynn effect. However, socioeconomic conditions and modern societal pressures can influence these scores.
Explanation:
The comparison of the IQ of an average 18-year-old today to their counterpart 60 years ago may likely reveal a significant increase. This increase can be attributed to the Flynn Effect, which postulates that there has been a consistent increase in IQ scores over the years, potentially due to improvements in nutrition, education, health, and a more stimulating environment.
However, this comparison must be made with care as numerous factors can influence IQ scores, including social structures and socioeconomic status. Children exposed to poverty and extreme stress, for instance, have been shown to experience reduced prefrontal brain functioning, potentially influencing their IQ scores negatively.
Also, modern pressures such as the increased prevalence of technology and social media may affect both cognitive development and IQ testing and interpretation, making comparisons more complex.
