Answer:
The correct answer is: The participants' abilities to solve geometry problems.
Explanation:
Researches contain both dependent and independent variables.
In a research the dependent variable is the variable that the researcher wants to identify if it changes by modifying the independent variables.
Independent variables are multiple factors that if modified they may or may not change the dependent variable.
In this particular case, Dr Martinez wants to prove the effects of diet on mental alertness. He proceeds to instruct the participants to eat breakfast that's either high in carbohydrates or high in protein (Independent variables) and then Dr. Martinez then measures the participants abilities to solve geometry problems (Dependent variable).
In conclusion, the dependent variable in this study is: Participants' abilities to solve geometry problems.
Answer:
They might have been written down and codified because they wanted to keep it more of a secret but idk i hope this helps
Explanation:
Answer:
Forgetting curve
Explanation:
Ebbinghaus invented the forgetting curve by using different ways of savings at various time intervals. Ebbinghaus modern memory research began by using meaningless strings of letters to study the capacity of our memory system. The amount of previously saved letters decreases rapidly, but then reaches a plateau after which a decrease in percentage savings is minimal. We start by forgetting rapidly without practice and then at a certain point forgetting occurs a much lesser rate. With practice, the forgetting curve would look different.
