Searching in the sand: Protracted video deficit in U.S. preschoolers' spatial recall using a continuous search space

Abstract

AbstractYoung children exhibit a video deficit for spatial recall, learning less from on‐screen than in‐person demonstrations. Some theoretical accounts emphasize memory constraints (e.g., insufficient retrieval cues, competition between memory representations). Such accounts imply memory representations are graded, yet video deficit studies measuring spatial recall operationalize memory retrieval as dichotomous (success or failure). The current study tested a graded‐representation account using a spatial recall task with a continuous search space (i.e., sandbox) rather than discrete locations. With this more sensitive task, a protracted video deficit for spatial recall was found in children 4–5 years old (n = 51). This may be due to weaker memory representations in the screen condition, evidenced by higher variability and greater perseverative bias. In general, perseverative bias decreased with repeated trials. The discussion considers how the results support a graded‐representation account, potentially explaining why children might exhibit a video deficit in some tasks but not others.Research Highlights The task used a continuous search space (sandbox), making it more difficult and sensitive than spatial recall tasks used in prior video deficit research. Spatial recall among 4‐ and 5‐year‐old children was more variable after watching hiding events on screen via live video feed than through a window. Children's spatial recall from screens was more susceptible to proactive interference, evidenced by more perseverative bias in an A‐not‐B design. The results demonstrate memory representations blend experiences that accumulate over time and explain why the video deficit may be protracted for more difficult tasks.
