“…These trials were considered to be lapse errors and were excluded from analysis. For the 125˚ target positions clearly falling outside normal children's field of view (Cummings et al 1988), often the participants initially searched for a target at the side of the ring opposite to the side where the illuminated target was located. Because no illuminated lamp could be detected, the participants then shifted their gaze to the other side of the ring, where the target lamp was to be found.…”

“…No significant difference (Mann-Whitney U test, p<0.05) in mean percentage of reversal responses was found between the seven children with lesions and their controls (50%, SD 26%; and 42.9%, SD 12.2% respectively). Target positions at 90˚ are located at the border of a child's field of view (Cummings et al 1988). One child with a right-hemisphere lesion and one child with a left-hemisphere lesion as well as three control children, (663) 2373 (574) 3036 (26) RH, right-hemisphere lesion; LH, left-hemisphere lesion.…”

In this preliminary study, visual search for targets within and beyond the initial field of view was investigated in seven school‐aged children (five females, two males; mean age at testing 8 years 10 months, SD1 year 3 months; range 6 to 10 years) with various acquired, postnatal, focal brain injuries (haematoma, haemorrhage, meningioma, neuroblastoma, and cerebral abscess) in anterior or posterior sites of the left or right hemisphere, and seven control children (matched for age and sex) were also studied. All participants attended mainstream primary schools. The children with lesions underwent surgery after diagnosis (mean age at diagnosis 5 years 4 months, SD 2 years 7 months). Group results indicated that for the overall scores on three psychometric tests of visuospatial and fine motor abilities (Southern California Figure Ground Perception Test, Visual Organization Test, and Visual‐Motor Integration Test), no difference between the children with left and right lesions was present. However, children with lesions in the right hemisphere, and not in the left hemisphere, took significantly more time than the controls to locate visual targets presented within and beyond the field of view. Examination of individual data suggested that, in accordance with brain imaging research, right‐sided anterior cerebral lesions sustained in early childhood might have an enduring detrimental effect on voluntary visual search performance during development. This persistent effect of early brain injury might imply that developmental plasticity of the brain does not apply to certain specific functions of particular areas of the right hemisphere.

“…Maturation of peripheral vision has been reported to occur as young as 5 years 2 and as old as 13 years of age, 3 with a range of peripheral vision maturities reported between these ages. [4][5][6][7][8][9][10][11] These vast maturity differences likely result from hugely different perimetric methods.…”

Normative visual field area, feasibility and repeatability using (Octopus) semi-automated kinetic perimetry are reported in 221 healthy volunteers aged 5-22 years. I4e and I2e stimuli assessed the visual field at 5 /second ( /s) or 3 /s. Blind spot was assessed with I2e at 2 /s. Reliable visual fields were plotted in 23% of participants 510 years, 64% of 10-12-year-olds, and 98% aged 13-22 years. Visual field areas were unchanged with age using 5 /s, but increased using 3 /s for I2e (p = 0.028). Blind spot area was unchanged with age. Reaction times reduced with age (p50.004). There was no learning effect. A test speed of 5 /s is recommended.

“…Visual fields are classically measured in terms of shifts in eye gaze to stimulus onsets in the periphery from a fixation at center. The evidence suggests that infants detect onsets in the periphery up to 90° from center and by 16 months up to 170° horizontally and vertically (Cummings et al, 1988; Tabuchi al, 2003). Head-cameras (with fields of view ranging from 60° to 100° diagonally as shown in Figure 2) do not capture the full visual field so defined.…”

Contributions of Head-Mounted Cameras to Studying the Visual Environments of Infants and Young Children

Head-mounted video cameras (with and without an eye camera to track gaze direction) are being increasingly used to study infants’ and young children’s visual environments and provide new and often unexpected insights about the visual world from a child’s point of view. The challenge in using head cameras is principally conceptual and concerns the match between what these cameras measure and the research question. Head cameras record the scene in front of faces and thus answer questions about those head-centered scenes. In this “tools of the trade” article, we consider the unique contributions provided by head-centered video, the limitations and open questions that remain for head-camera methods, and the practical issues of placing head-cameras on infants and analyzing the generated video.
