Hippocampal function in the rat: cognitive mapping or vicarious trial and error?

A Amsel1

Summary

This study challenges the cognitive map hypothesis of hippocampal function. It proposes that the hippocampus may instead support vicarious trial and error in spatial learning.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Behavioral Neuroscience

Background:

  • The hippocampus is widely hypothesized to function as a "cognitive map" for spatial learning.
  • This hypothesis is primarily supported by studies using tasks like the radial-arm maze and Morris water maze.
  • Recent discussions have debated the evidence for the cognitive map hypothesis.

Purpose of the Study:

  • To propose an alternative hypothesis for hippocampal function in spatial learning.
  • To re-examine E. C. Tolman's theories in the context of hippocampal research.
  • To challenge the prevailing cognitive map theory of the hippocampus.

Main Methods:

  • Speculative commentary and theoretical review.
  • Analysis of existing literature on hippocampal function and spatial learning.
  • Reinterpretation of E. C. Tolman's concepts of "cognitive map" and "vicarious trial and error."

Main Results:

  • The study presents an alternative to the cognitive map hypothesis.
  • It suggests the hippocampus may be involved in "vicarious trial and error" during simple discrimination learning.
  • This alternative function is based on conflicting approach-avoid dispositions.

Conclusions:

  • The hippocampus's role in spatial learning may not be solely as a cognitive map.
  • An alternative function, vicarious trial and error, is proposed based on Tolman's work.
  • This perspective offers a new framework for understanding hippocampal contributions to learning and behavior.
