Gaze fixation takes place at which age ?
**Core Concept**
Gaze fixation is a crucial developmental milestone in infants, indicating the maturation of the visual system and the ability to focus on a specific object or point. This cognitive skill is closely linked to the development of the brain's visual processing centers, particularly the occipital lobe.
**Why the Correct Answer is Right**
Gaze fixation typically occurs around 6-8 weeks of age, when the infant begins to show a preference for looking at faces and objects. This is an essential step in social and cognitive development, as it enables infants to explore their environment and interact with their caregivers. The ability to fixate gaze is thought to be mediated by the maturation of the visual cortex, particularly the area V1, which is responsible for processing basic visual information.
**Why Each Wrong Option is Incorrect**
**Option A:** 1-2 weeks of age - Gaze fixation is not established at this age, as the visual system is still immature.
**Option B:** 3-4 months of age - While infants have improved visual acuity at this age, gaze fixation is typically established earlier.
**Option C:** 9-10 months of age - This is beyond the typical age range for gaze fixation, which is usually established by 6-8 weeks.
**Clinical Pearl / High-Yield Fact**
Infants with visual impairments or neurological disorders may exhibit delayed or absent gaze fixation, which can be an important clinical indicator of developmental delays or underlying pathology.
**Correct Answer:** B. 3-4 months of age
