Cue combination occurs when two independent noisy perceptual estimates are merged together as a weighted average, creating a unified estimate that is more precise than either single estimate alone. Surprisingly, this effect has not been demonstrated compellingly in children under the age of 10 years, in contrast with the array of other multisensory skills that children show even in infancy. Instead, across a wide variety of studies, precision with both cues is no better than the best single cue – and sometimes worse. Here we provide the first consistent evidence of cue combination in children from 7–10 years old. Across three experiments, participants showed evidence of a bimodal precision advantage (Experiments 1a and 1b) and the majority were best-fit by a combining model (Experiment 2). The task was to localize a target horizontally with a binaural audio cue and a noisy visual cue in immersive virtual reality. Feedback was given as well, which could both (a) help participants judge how reliable each cue is and (b) help correct between-cue biases that might prevent cue combination. A feedback effect was found in Experiment 2, with children who were given single-cue feedback showing the highest rate of cue combination. Given this, we suggest that children at 7–10 years old are capable of cue combination in principle, but must have sufficient representations of reliabilities and biases in their own perceptual estimates as relevant to the task, which can be facilitated through task-specific feedback.

“…In terms of sensory augmentation, two studies have been done that stand in stark contrast. One found that adults can integrate augmented sensory skills with their typical repertoire (Negen et al, 2017), but the other found that they did not (Goeke et al, 2016). The study with feedback showed integration, but not the study without feedback.…”

“…First, it is not clear that audiovisual localization is something that children can practice more frequently than visual depth (Dekker et al, 2015), and it fails to explain why the other audio-visual study (Gori et al, 2012) did not find a bimodal precision advantage. Second, modelling the acquisition of cue combination as purely a function of cue exposure runs aground of a recent finding in adults (Negen, Wen, Thaler, & Nardini, 2017). In a 5-hour task, adults were able to combine a new audio cue to depth with a familiar but noisy visual cue to depth.…”

“…Integration of different visual features such as stereo and motion or texture, which has been found to occur in adults (Johnston, Cumming, & Landy, 1994;Knill & Saunders, 2003), may be slower to develop, as depth processing is calibrated to account for the changing position of the eyes in a growing head, in a manner similar to how integration of visuohaptic information relies on the calibration of the developing haptic system (Ernst, 2008;Gori et al, 2008). Adults can learn novel cue combination within a few hours (Negen, Wen, Thaler, & Nardini, 2018), suggesting that the slow development of multisensory cue combination may be limited by biological development (Negen et al, 2019).…”

Stronger saccadic suppression of displacement and blanking effect in children

Humans do not notice small displacements to objects that occur during saccades, termed saccadic suppression of displacement (SSD), and this effect is reduced when a blank is introduced between the pre-and postsaccadic stimulus (Bridgeman, Hendry, & Stark, 1975; Deubel, Schneider, & Bridgeman, 1996). While these effects have been studied extensively in adults, it is unclear how these phenomena are characterized in children. A potentially related mechanism, saccadic suppression of contrast sensitivity-a prerequisite to achieve a stable percept-is stronger for children (Bruno, Brambati, Perani, & Morrone, 2006). However, the evidence for how transsaccadic stimulus displacements may be suppressed or integrated is mixed. While they can integrate basic visual feature information from an early age, they cannot integrate multisensory information (Gori, Viva, Sandini, & Burr, 2008; Nardini, Jones, Bedford, & Braddick, 2008), suggesting a failure in the ability to integrate more complex sensory information. We tested children 7 to 12 years old and adults 19 to 23 years old on their ability to perceive intrasaccadic stimulus displacements, with and without a postsaccadic blank. Results showed that children had stronger SSD than adults and a larger blanking effect. Children also had larger undershoots and more variability in their initial saccade endpoints, indicating greater intrinsic uncertainty, and they were faster in executing corrective saccades to account for these errors. Together, these results suggest that children may have a greater internal expectation or prediction of saccade error than adults; thus, the stronger SSD in children may be due to higher intrinsic uncertainty in target localization or saccade execution.
