The contextual cueing effect disappears during joint search in preschool children

Abstract

During preschool years, children's interacting with others increases. One of the involved developmental skills is task co -representation, through which children aged 5 years and older rep-resent a partner's task in a similar way to their own task. In adults, task co-representation makes participants attend to and form memories of objects relevant to both their own task and their part-ner's task; however, it is unclear whether children can also form such memories. In Experiment 1, we examined the memory facili-tation of joint search using a contextual cueing effect paradigm. Children were presented with search displays repeatedly with the same or random layouts and searched and responded to the target either alone (the single group; n = 32; M[age] = 73.6 months, range = 61-80) or with their parent (the joint group; n = 32; M[age] = 74.3 months, range = 64-81). Results showed that the search with the same layouts was faster than that with the random lay-outs for the single group, indicating that children form associative memories of target and distractors relevant to their own task. For the joint group, this effect was not statistically different from that of the single group, with exploratory analysis suggesting that it was disrupted. In Experiment 2, children performed the search with a peer (n = 32; M[age] = 72.7 months, range = 67-79) and the effect was also not found. Our findings suggest that the self's and partner's tasks are represented but might not be incorporated into associative memory in 5-and 6-year-old children.(c) 2022 Elsevier Inc. All rights reserved.
