Blocking spatial navigation across environments that have a different shape.

Area of Science:

• Cognitive Psychology
• Neuroscience
• Spatial Cognition

Background:

• The geometric module hypothesis suggests a global spatial representation is immune to interference.
• However, research indicates animals and humans use local geometric cues for navigation.
• The Miller-Shettleworth model proposes geometric cues compete for associative strength like other cues.

Purpose of the Study:

• To investigate if human learning of local geometric cues aligns with the Miller-Shettleworth associative model.
• To test the interaction between learning local geometric cues and non-geometric cues.

Main Methods:

• Experiment 1 replicated findings on navigational behavior transfer between rectangular and kite-shaped environments.
• Experiments 2 and 3 used blocking paradigms to assess cue interactions.
• Participants learned navigational tasks involving geometric and non-geometric environmental features.

Main Results:

• Navigational behavior successfully transferred between different geometric shapes (rectangle and kite).
• Learning of non-geometric cues was blocked by learning local geometric cues.
• Learning of local geometric cues was also blocked by learning non-geometric cues (reciprocal blocking).

Conclusions:

• The observed reciprocal blocking is consistent with associative theories of spatial learning.
• Current global-shape encoding theories struggle to explain these findings.
• Human spatial learning appears to involve associative competition between geometric and non-geometric cues.
