Answer:
It is the experimental condition.
Step-by-step explanation:
In the experiment given in the question, the amount of sleep is the independent variable and the number of photographs they remember is the dependent variable because it depends on the amount of sleep.

The experimental condition is the variable that is changed to let the researcher observe the effects on the dependent variable.
