You can do two things at once. Whether you will remember either of them is a different question.
Encoding versus retrieval
Dual-task research has found an asymmetry worth knowing: dividing attention during encoding severely impairs later memory, while dividing attention during retrieval has a much smaller effect on accuracy. Encoding appears to require attentional resources in a way retrieval does not to the same degree. Practically, this means listening to a lecture while messaging costs you the lecture content, and the cost is incurred at the moment rather than later.
Why it is switching, not parallelism
For tasks requiring central cognitive processing, apparent multitasking is generally rapid alternation with switch costs at each transition. The psychological refractory period - the delay in responding to a second stimulus presented shortly after a first - demonstrates a central bottleneck. Studies of people who self-identify as strong multitaskers have generally found them to perform worse on relevant measures, not better.

See Cognizil PricingWhere automaticity changes it
Highly practised tasks become automatic and require little central capacity, which is why you can walk and converse. The limits appear when both tasks require the same resources or when one becomes non-routine - which is why a conversation is fine while driving a familiar road and becomes a problem in unexpected traffic. The relevant question is never whether you can do both but whether either is demanding central processing at that moment.
Key takeaways
- Divided attention at encoding is far more damaging than at retrieval
- The psychological refractory period demonstrates a central processing bottleneck
- Self-identified strong multitaskers generally perform worse, not better
- Automaticity frees capacity, but only while the task stays routine
