What outcomes were recorded in the study?

• A. Sleep patterns, feeding schedules, crying frequency
• B. Number of words, quality/type of interaction, growth in words
• C. Reading level, IQ, math skills
• D. Music exposure, screen time, play preferences

Answer: (B)

In language development studies, the focus is on concrete language outcomes that show how a child’s communication grows. The recorded measures—number of words produced, the quality or type of social–linguistic interaction, and growth in words over time—directly track vocabulary size, how the child uses language in interactions, and how their vocabulary expands. These are the outcomes that reveal language progress. The other options mix in areas not central to language development: sleep patterns, feeding schedules, and crying frequency point to physiological or behavioral states; reading level, IQ, and math skills cover broader cognitive abilities; music exposure, screen time, and play preferences are environmental factors or preferences rather than language outcomes.
