A recent study at Yale University’s Infant Cognition Center, published in the journal Nature, investigated whether babies develop social preferences at an early age. As part of the study, 16 six month- old infants were each shown a sequence of videos. One video focused on a figure whose actions toward others were helpful, while the other focused on a figure whose actions were hurtful. After viewing the videos, each infant was presented with the two figures and allowed to choose one to play with. Of the 16 infants in the study, 14 chose to play with the helper object. The researchers concluded that six-month-old infants have both the ability to recognize and the preference to align themselves with the helpful figure. Identify
