A Comparative Study of Memory Recall Across Different Sensory Inputs on Short-Term and Long-Term Memory

Overview

With increasing use of technology, many students struggle with remembering information after learning a lesson. Studies have shown that memory is also tied to the types of sensory input. This project looks at how different sensory inputs affect short term and long term memory recall across four different groups: sight-only, hearing-only, multisensory (smell, hearing, touch, and sight ), and VR interaction. Ten objects were selected and made in Blender to create 3D models of each object. 24 Middle school students were assigned into 4 groups equally and each object was presented for 5 seconds. Each group interacted with the object based on the group’s assigned sensory input. Each participant then had 90 seconds to write down as many objects as they could remember. To determine long-term memory scores, after 5 days, the students were tested again and given 90 seconds to write down as many objects as they could recall. My hypothesis was that VR interaction would have the best short term and long term memory recall. The results showed that my hypothesis was half-true. The VR had the best memory recall rate for long term memory with an average of 6.3 objects out of 10 and Multi sensory had the best short term memory recall with an average of 9 objects out of 10. This project can help classrooms, training programs, or educational software educators to make learning more effective. This project may also help therapists aid those suffering from memory-loss.
