Answer:
Replication
Explanation:
The 3 main principles of experimental deisgn
1. Randomisation
2. Replication
3. Blocking
Replication
This has different definition. It is when a researcher repeats that is replicate research findings through correct use of operational definitions, procedures, etc.
A good research mut be replicated and it must result in the same or similar in terms of findings each time the experiment is performed.
It also implies that the treatment used in an experiment was used more than once in an experiment. It because allows us to estimate the inherent variability in the data. This allows us to know and judge if an observed difference in treatment was as a result that is it could be due to chance variation.
Replication is very important because when we have one experiment or treatments once, we would not know if the observed difference is due to the treatments or just random variability. But replication helps you to know the reason for the observed differences.

Answer:
Cognitive maps
Explanation:
n E. C. Tolman's experiment, some rats were trained to run through mazes for standard food goals, while other rats were allowed to explore the mazes for 10 days without food goals or other rewards. Later, when food rewards were placed in a box at the far end of the maze, the previously unrewarded rats reached the food box as quickly as the rewarded rats after only one or two trials. This experiment demonstrated that the rats had the ability to form cognitive maps of their surroundings.
Cognitive map is any visual representation of a person's mental model for a given process or concept i.e the mental image of the attributes of our environment. This maps help an individual to acquire, code, store, recall and decode information about the relative locations and attributes in their spatial environment.
Cognitive maps help us lay out ideas, processes, and recognize the pattern and relationship.
In E. C. Tolman's experiment, the rat use cognitive maps to find where rewards in the box are located because the rats are able to create and use cognitive maps to help them navigate their environment
