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.

The correct answer is: "semantic encoding".

In general, encoding techniques are applied in order to elaborate on the information perceived by our senses, seeking to appropiately store it in our longer lasting memory units and to optimize subsequent retrieval.

Semantic encoding consists on relating certain concepts to a context in order to remember them better afterwards, using mechanisms such as chunking or mnemonics. This is the case in the research described where, in order to remember a list of objects, participants connect them to a house context.

Answer:

"industry vs. inferiority" stage

Explanation:

Erik Erikson proposed a theory about social and emotional development along people's lifespan. According to him, people go through different stages in life that are manifested as "crisis" where two different options present to the people and they create anxiety. Eventually, the person is inclined towards one of the two options available and solves the crisis and moves on to the next stage.

Erikson's fourth psychosocial crisis, is called "industry vs. inferiority" occurs between the ages of five and twelve.

During this stage, the child feels the need to win approval by demonstrating specific competencies that are valued by society and begin to develop a sense of pride in their accomplishments. When they are reinforced for their initiative they will feel industrious (competent) and confident in their ability to achieve goals. If they are not reinforced, they might feel inferior, doubting their own abilities and not reaching their full potential and can develop a feeling of inferiority.

Sammy is in third grade, so he must be around <u>9 years old,</u> he won the spelling bee and felt proud about it since <u>he demonstrated a specific competency </u>in his school (thus he felt competent), however, <u>when he couldn't complete his arithmetic assignment he felt incompetent </u>(this could case him feelings of inferiority or doubt of his own abilities).

We can see how Sammy is in the "industry vs. inferiority" stage where he's looking to be competent and developing a sense of pride in his accomplishments.
