Developmental aspects of consciousness: how much theory of mind do you need to be consciously aware?

Summary
Children likely become consciously aware of events in the world between 12 and 15 months of age, with a possible range of plus or minus 3 months. This conclusion emerges from evaluating five strategies: three look for signs of verbal communication, executive control, or explicit memory—activities that require conscious awareness in adults; two consider when children can engage in the minimal higher-order thought needed for access consciousness and phenomenal consciousness. The answer is tentative, based on converging evidence from these different approaches.

Abstract
When do children become consciously aware of events in the world? Five possible strategies are considered for their usefulness in determining the age in question. Three of these strategies ask when children show signs of engaging in activities for which conscious awareness seems necessary in adults (verbal communication, executive control, explicit memory), and two of the strategies consider when children have the ability to have the minimal form of higher-order thought necessary for access consciousness and phenomenal consciousness, respectively. The tentative answer to the guiding question is that children become consciously aware between 12 and 15 months (+/-3 months).
