Answer:
Within-Subjects Experiments
Explanation:
Within-Subjects Designs: this is a form of experimental design in which the participants involved is exposed or subjected to all the conditions. 
However, in this case, Alberto, is using Within-Subject Designs (simultaneous) by exposing all the participants to answer arithmetic problems while listening to metal, and then country, and finally classical music simultenously.
The multiple conditions here are: arithmetic problems to solve, listening to different types of music in a sequence that mixed the different types.
 
        
             
        
        
        
 Problem-solving strategies which don't guarantee solutions, but make efficient use of time is Heuristics.
Any problem-solving strategy that employs a practical approach or numerous short cuts in order to provide answers that might not be ideal but are adequate given a constrained timeline or deadline is known as a heuristic, or heuristic technique.
Heuristic methods can be used to expedite the process of obtaining a workable solution in situations when it is impossible or impractical to discover an ideal one. Heuristics are mental efficiencies that reduce the cognitive strain of decision-making. Heuristics are tactics developed from prior experiences with challenges that are comparable.
