A Correct answer
Explanation

Declarative memory involves the ability to remember facts, concepts, and events.

Multiple choice

Which of the following is a mathematical model of memory that assumes that memory is a series of interconnected nodes?

  1. The Atkinson-Shiffrin Model

  2. The Multi-Store Model

  3. The Spreading Activation Model

  4. The Decay Theory of Forgetting
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Spreading Activation Model assumes that memory is a network of interconnected nodes, and that the strength of the connections between nodes determines the likelihood that one node will activate another.

Multiple choice

According to the Atkinson-Shiffrin Model, what are the three main components of memory?

  1. Sensory Memory, Short-Term Memory, and Long-Term Memory

  2. Working Memory, Episodic Memory, and Semantic Memory

  3. Declarative Memory, Non-Declarative Memory, and Procedural Memory

  4. Explicit Memory, Implicit Memory, and Prospective Memory
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Atkinson-Shiffrin Model divides memory into three main components: Sensory Memory, which stores information for a very brief period of time; Short-Term Memory, which stores information for a few seconds or minutes; and Long-Term Memory, which stores information for an indefinite period of time.

Multiple choice

According to the Multi-Store Model, what are the two main types of memory?

  1. Sensory Memory and Short-Term Memory

  2. Short-Term Memory and Long-Term Memory

  3. Working Memory and Long-Term Memory

  4. Episodic Memory and Semantic Memory
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Multi-Store Model divides memory into two main types: Short-Term Memory, which stores information for a few seconds or minutes; and Long-Term Memory, which stores information for an indefinite period of time.

Multiple choice
