Selective attention is a psychological term that refers to the ability to focus on one task and filter out all other irrelevant sensory information.
<u />
<u>Clay displays a greater level of selective attention</u>, because he's easily able to tune out the sound of the crowd and focus only on the game. On the other hand, <u>Bruce has a lower level of selective attention</u>, because he can't discriminate what he should be focusing his attention on, and it's often distracted by his opponents and the crowd.

The hypothetical-deductive method has several essential steps: observation of the phenomenon to be studied, creation of a hypothesis to explain said phenomenon, deduction of consequences or propositions more elementary than the hypothesis itself, and verification or verification of the truth of the deduced statements. .
Explanation:
<u>We could say that this method was very aptly applied in the case of children of children of the peace movement in Colombia, because first The situation or problem was observed and recognized ;</u>more than 140 student leaders formed a special council. They divided into various "commissions" to discuss different aspects of the conflict. There was a commission for the construction of peace, a commission for human rights, another for displaced persons, etc. They met in a large room, with each commission supported by one of the adults. For many of the students, the idea of being asked what they thought about war and how they could help peace was a revelation. An example of this was that of Farlis Calle, who was then fifteen years old and who later became a prominent leader in the National Movement for Children for Peace, asked why they did not teach peace education in Colombian schools. "How can we learn to be peaceful if our teachers don't help us understand what it means? No one here has lived in peace. We have been fighting from the moment we were born. "At the end of the two-day session, the various commissions had come up with many suggestions: for peace education, recreation projects, cultural events, and" a youth movement working for peace.
<u>After taking advantage of Machel's visit, Farlis Calle had been chosen by the students as the first child mayor of Apartad & oacute; and they believed that this gave them the constitutional right to form a local government of children. So here come the proposals and verification of results</u> by means of which notices were sent to the municipal schools, for others to know that they could and should participate in their government , and soon as many as 200 children attended peace meetings three times a week, gathering on soccer fields and parks.
Answer:
Training a model using labeled data and using this model to predict the labels for new data is known as: <u>Supervised Learning.</u>
Explanation:
Supervised learning is a set of techniques that allows future predictions based on behaviors or characteristics analyzed in labeled historical data. A label is nothing more than the output that the data set has returned for historical data, already known. In supervised learning, it assumes that we start from a previously labeled data set, that is, we know the value of the target attribute for the data set that we have.
Answer: Confounded
Explanation: A confounded study simply means an experiment or study in which a confounding or lurking variable has been introduced which will impact or cause a distortion between both the dependent and independent variable resulting in a spurious relationship.
In the scenario above, aggressive children were subjected to aggressive movies and non-aggressive children were subjected to non-aggressive movies. A lurking or confounding variable has been introduced such that a correlation or causal relationship cannot be correctly established.
