Figure 4.

Infants born preterm showed differences from infants born full-term (FT) in the ability to match their behavioral performances to the properties of objects. Infants born preterm had delays in or the absence of this ability across multiple behaviors. Differences were most pronounced for infants born preterm with significant brain injury (PTBI). Cells shaded in gray represent visits during which increased behavioral performance was observed for objects with properties expected to elicit more of a behavior; dark gray cells represent significant differences (P≤.006), and light gray cells represent trends for differences (P≤.01). White cells represent visits during which infants exhibited the behavior similarly with all objects regardless of their properties. See Table 2 for details on the properties expected to elicit each behavior and eTable 3 for supporting statistical data. PT no BI=preterm without significant brain injury.
