<span>Despite the fact that
China's agriculture output is the biggest on the planet, just around 15% of its
total land zone can be used to cultivate. China's arable land, which makes
about 10% of the total arable land on the planet, supports more than 20% of the
total populace.</span>
<span>Chunking increases the capacity of short-term memory by recoding information into more meaningful units. When large amounts of information are given, short-term memory usually remembers the first set of unrehearsed information (primacy) or the last set of unrehearsed information (recency), but few things from the middle.</span>
Answer to Question 1:
The behaviour of the students who hastily write what they consider a "C" level essay after being repeatedly told they can't make an "A" or "B" is a consequence of Reinforcement.
The answer, therefore, is D.
Explanation:
Reinforcement in behavioural psychology refers to the process of encouraging or entrenching a belief system or pattern of behaviour. It can also be defined as any stimuli which stimulate a thought pattern and engrains the probability of a specific response to a particular stimulus. Reinforcements are usually more effective when it comes from a person of perceived to be in a position of authority.
The high school students were verbally programmed by the instructor, who has the authority to mark their scripts, into thinking they will never be able to make an "A" or a "B". The result is that the students didn't even try to put in efforts that would have led to an A or a B because even if they did, the instructor has the power to ensure that no one score an "A" or a "B".
The challenge here is not that the students couldn't write "A" grade essays. In their mind, there was no point trying given that the ability lay with the instructor to ensure that what he said will happen. In any case, the instructors intended behavioural response was achieved.
2. The correct answer to the question of Acquisition and Extinction as indicated on the graph is B.
The strength of the response increases then decreases over time.
Acquisition happens when a neutral stimulus turns into a conditioned stimulus.
When a behavior begins to diminish or even disappear completely as a result of the gradual removal of a conditioned response, extinction is said to have occurred.
