QCM : Perception and Sensory Processes — 9 questions

Explication

The hippocampus is the key brain structure involved in forming and consolidating new memories. It plays a crucial role in converting short-term memories into long-term ones.

Explication

The hippocampus is essential for encoding and consolidating new explicit memories, including episodic and semantic memories. The amygdala, not the hippocampus, processes emotional memories.

Explication

Recall requires actively retrieving information without any cues, such as answering an essay question. Recognition involves identifying learned information when presented with cues, like multiple-choice questions. Recognition is generally easier than recall.

Explication

Short-term memory typically holds about 7 ± 2 items for approximately 20 seconds, indicating its limited capacity and duration.

Explication

Sensory adaptation is the process where sensory receptors become less responsive to a constant stimulus over time, reducing sensitivity and allowing us to focus on changes in our environment.

Explication

The primacy effect refers to the tendency to better recall the first items in a list, often due to more rehearsal and encoding.

Explication

Recognition is typically easier than recall because it involves identifying previously learned information with the help of cues, reducing the search effort.

Explication

Proactive interference occurs when earlier memories hinder the acquisition of new information, impairing new learning.

Explication

The forgetting curve, proposed by Ebbinghaus, shows that memory retention declines exponentially, with most forgetting occurring shortly after learning.
