A study investigated whether smartphone multitasking during a lecture affects students’ recall. The sample consisted of UK college students.
During a lecture, one group listened while being encouraged to use their smartphones for unrelated activities (e.g., scrolling or checking emails). The other group listened with their smartphones kept out of reach. After the lecture, all students completed a 20-question recall test on the lecture content.
Two months later, the procedure was repeated, with students switching conditions. Scores were converted into percentages.
Table 1 shows the mean recall scores and standard deviations for each condition.
Table 1: Mean and standard deviation scores of recall per condition
Condition | Mean recall score | Standard deviation |
Smartphone | 36.5% | 4.6 |
No smartphone | 68.2% | 1.4 |
