The results of my study were very interesting. The results showed that Sign Language leads to verbal language acquisition faster than the Picture Exchange Communication System. However, I don't find these results to be 100% valid as I only had two participants assigned to Sign Language and one participant assigned to the Picture Exchange Communication System. Therefore, having only three participants leaned the results in favor of the two participants using Sign Language.
Overall, I enjoyed the research process and learned a lot from executing the interventions and data collection. I learned that having more than three participants is crucial in order to obtain accurate and valid data. I also learned that when doing research with children under the age of three, you need to account for the many uncontrollable factors such as nap times, illness, family vacations, and families forgetting appointment times. If I were to do another study in the future, I would take this lessons into account and create a study with more participants, extend the studies duration, and get more professionals to assist with execution of interventions with the participants in order to obtain more reliable and valid results.
