BlackTom AI · Accepted Answer

The question concerns findings from Tamis-LeMonda and colleagues about multi-modal interactions across three cultural groups: Dominican, Mexican-American, and African-American mother–infant dyads. We will evaluate each option in turn to understand which statement aligns with the reported results.

Option 1: 'none of the mothers in these three cultures used multi-modal interactions with their infants.' This claim asserts a complete absence of multi-modal interactions across all three cultures. The original research specifically highlights the presence and variety of multi-modal cues in mother–infant exchanges rather than an absence, so this option is inconsistent with the documented findings and is therefore incorrect.

Option 2: 'although mothers in some cultures used mult-modal interactions with their infant, in some cultures mother relied only on speech in their interactions.' This option suggests that certain cultures used solely speech while others used multi-modal cues, implying a strict exclusivity by culture. The study’s conclusion emphasizes that multi-modal interactions are used across cultures, not that some cultures abandon them entirely in favor of speech alone. Hence, this statement mischaracterizes the cross-cultural pattern and is not supported by the findings.

Option 3: 'mothers used multi-modal interactions at home, but not when they were observed in the lab.' This option differentiates home and laboratory contexts. The comparison in the study concerns cultural differences in the use of multi-modal interactions broadly, not a context-specific discrepancy between home and lab. Without evidence of a lab-related drop across all groups, this claim is speculative and not aligned with the reported results.

Option 4: 'across all cultures, mothers used more multi-modal interactions than just speech or just touch.' This option captures the essence of the reported pattern: across Dominican, Mexican-American, and African-American mother–infant dyads, mothers employed a variety of cues (e.g., touch in addition to language) rather than relying solely on speech or solely on touch. This aligns with the concept of multi-modal interactions as a composite use of cues beyond a single channel, consistent with the study’s conclusions.

In summary, the incorrect options misstate the presence, exclusivity, or contextual conditions of multi-modal interactions, while the fourth option accurately reflects the cross-cultural finding that mothers integrate multiple cues rather than relying on a single modality in their interactions with infants.
