Digital SATReading and Writing: Information and IdeasMedium
A research article discusses the phenomenon of 'cognitive load' in learning. It states that when individuals are presented with too much new information simultaneously, their working memory becomes overloaded, hindering the transfer of information to long-term memory. The article then describes an experiment where two groups learned a complex task: Group A received all instructions at once, while Group B received the same instructions broken down into smaller, sequential steps. Group B significantly outperformed Group A in both immediate recall and long-term retention of the task. Which of the following statements is a logical inference based on the information presented?
- AThe complexity of a task is the sole determinant of cognitive load experienced by learners.
- BPresenting all information at once is beneficial for learners with high working memory capacity.
- CLong-term memory capacity is inherently limited, regardless of presentation method.
- DReducing cognitive load by chunking information improves learning outcomes.
Show answer & explanationAnswer & explanation
Correct answer: D. Reducing cognitive load by chunking information improves learning outcomes.
The article defines cognitive load and how it hinders learning when information is 'too much.' The experiment shows that 'broken down into smaller, sequential steps' (chunking) led to 'significantly outperformed' results. This directly supports the inference that reducing cognitive load through chunking improves learning.
Why the other options are wrong
- A. The article implies that the *presentation method* (how info is given) also impacts cognitive load, not just task complexity.
- B. The experiment showed Group A (all at once) performed poorly, and the article states 'too much new information' is problematic, contradicting this idea.
- C. The article focuses on working memory and transfer, not the inherent limits of long-term memory itself.
Logical Inference
A conclusion that necessarily follows from the premises or evidence provided, even if not explicitly stated.
- Must be directly derivable from the given text.
- Avoids introducing new information or assumptions.
- Represents the most probable conclusion based on the facts.
