Abstract: | This thesis investigated developmental changes in temporal perception of hearing and touch (audiotactile). Three empirical chapters provide converging evidence on the unique characteristics of this modality pairing. In Chapter 2, a simultaneity judgment task assessed temporal perception. Three groups of children (aged 7-, 9-, and 11-years-old) were compared to a group of adults, examining measures such as the temporal simultaneity window and the point of subjective simultaneity. By age 11, mature temporal perception between hearing and touch was observed. Chapter 3 investigated developmental changes in temporal-based integration using the fission and fusion illusions. The study involved comparing three groups of children to adults (aged 9-, 11-, and 13-years-old). The measure of illusion strength combined with a signal detection analysis demonstrated that children did not exhibit adult-like integration until around age 13. Chapter 4 explored the potential impact of short-term congenital visual deprivation on hearing and touch temporal perception. An audiotactile simultaneity task was used to test a group of adults who received treatment for congenital bilateral cataracts. The results of this final experiment are considered preliminary because of limitations imposed by the COVID-19 pandemic; instead of the planned age- and gender-matched control participants, we utilized the adult data from Chapter 2 for comparison. The General Discussion provides a comprehensive account of how these findings relate to one another and how they situate in the broader literature. Additionally, a novel hypothetical theory is presented, incorporating the established causal inference framework, to offer insights into observed changes in multisensory perception across development. |
