The Correct Answer and Explanation is:
The correct answer is “Semantic”.
Explanation:
Semantic networks and connectionist networks are two models that explain how information is organized and processed in memory. Each model offers a different perspective on how the brain stores and retrieves knowledge.
- Semantic Networks
Semantic networks propose that information in memory is organized in a web-like structure. In this model, nodes represent concepts or ideas, and connections (or links) between nodes represent relationships between these concepts. For example, the concept “bird” might be connected to “can fly,” “has wings,” and “animal.” When one concept is activated (e.g., “bird”), related concepts are also activated through a process called spreading activation, making retrieval more efficient. This model explains phenomena like why recalling one memory can trigger associated ideas and why we recognize patterns or categories quickly. - Connectionist Networks (Neural Networks)
Connectionist networks, inspired by neural structures in the brain, are based on the idea of distributed processing. Here, information is stored as patterns of activation across many interconnected nodes (similar to neurons). These networks rely on the principles of parallel distributed processing (PDP), meaning multiple pieces of information are processed simultaneously. Each “neuron” contributes to the overall pattern, allowing for robust storage and the ability to recover information even when some nodes are disrupted. Learning in connectionist networks involves adjusting the strength of connections (synaptic weights), simulating how the human brain learns through experiences.
Comparison and Integration
While semantic networks focus on how concepts are explicitly structured, connectionist networks explain the underlying mechanisms of learning and memory. Together, these models provide a comprehensive understanding of cognitive processes. The semantic network highlights the relationships among stored knowledge, and the connectionist approach emphasizes how this knowledge is encoded and processed biologically.
By understanding both models, researchers can better explore memory-related processes, like learning, retrieval, and forgetting, which have applications in fields such as education, artificial intelligence, and therapy.
