Objective: Information foraging is atypical in both autism spectrum disorders (ASDs) and ADHD; however, while ASD is associated with restricted exploration and preference for sameness, ADHD is characterized by hyperactivity and increased novelty seeking. Here, we ask whether similar biases are present in visual foraging in younger siblings of children with a diagnosis of ASD with or without additional high levels of hyperactivity and inattention. Method: Fifty-four low-risk controls (LR) and 50 high-risk siblings (HR) took part in an eye-tracking study at 8 and 14 months and at 3 years of age. Results: At 8 months, siblings of children with ASD and low levels of hyperactivity/inattention (HR/ASD-HI) were more likely to return to previously visited areas in the visual scene than were LR and siblings of children with ASD and high levels of hyperactivity/inattention (HR/ASD+HI). Conclusion: We show that visual foraging is atypical in infants at-risk for ASD. We also reveal a paradoxical effect, in that additional family risk for ADHD core symptoms mitigates the effect of ASD risk on visual information foraging.

Purpose – The purpose of this paper was to study users’ behaviour when using different search engine results pages (SERPs) to identify what types of scents (cues) were the most useful to find relevant information to complete tasks on the Web based on information foraging theory. Design/methodology/approach – This study has designed three interface prototypes and conducted a qualitative study using the protocol analysis methodology. The subjects were recorded and videotaped to identify patterns of searching behaviours on visualization interfaces of SERPs. Findings – The study found that users found titles of categories or websites, keywords of categories, orientation of results and animation are strong scents that users follow to help find information on SERPs. If certain scents are not used followed on an interface, then their strength will diminish. Furthermore, the study showed that simple scent trails are more important to users than complicated trails. Originality/value – This study uses a qualitative approach to explore how users behave with different SERP formats, particularity a visualization format, and identify which scents on the interface are important for users to follow to successfully complete tasks on the Web.
