As If

Three experiments are reported which aim to distinguish between mechanisms that might serve joint visual attention between human infants and adults. Between 6 and 18 months of age, the infant will adjust his (or her) line of gaze contingent on a change in the adult's focus of attention but behaves as if the adult is referring to loci within the infants' visual space. Thus, if the adult looks behind the infant, the infant scans the space in front of him. Various explanations of this phenomenon and of the capacity for joint visual attention are discussed.

AbstractReduced retinal illuminance affects colour perception in older adults, and studies show that they exhibit deficiencies in yellow-blue (YB) discrimination. However, the influence of colour cues on the visual attention in older individuals remains unclarified. Visual attention refers to the cognitive model by which we prioritise regions within the visual space and selectively process information. The present study aimed to explore the effect of colour on visual search performance in older observers. In our experiment, younger observers wearing glasses with a filter that simulated the spectral transmittance of the aging human lens and older observers performed two types of search tasks, feature search (FS) and conjunction search (CS), under three colour conditions: red-green, YB, and luminance. Targets and distractors were designed on the basis of the Derrington–Krauskopf–Lennie colour representation. In FS tasks, reaction times changed according to colour in all groups, especially under the YB condition, regardless of the presence or absence of distractors. In CS tasks with distractors, older participants and younger participants wearing glasses showed slower responses under chromatic conditions than under the achromatic condition. These results provide preliminary evidence that, for older observers, visual search performance may be affected by impairments in chromatic colour discrimination.
