Blocking of goal-location learning based on shape.

Area of Science:

• Cognitive Psychology
• Spatial Cognition
• Learning and Memory

Background:

• Spatial learning involves acquiring knowledge about the environment.
• Blocking is a phenomenon where prior learning hinders new learning.

Purpose of the Study:

• To investigate the blocking effect in spatial learning within virtual environments.
• To determine if preliminary training with one cue (Shape A) blocks learning about another cue (Shape B) for a goal location.

Main Methods:

• Five experiments were conducted using desktop, computer-simulated virtual environments (VEs).
• Participants were trained to locate a goal using Shape A.
• The effect of auxiliary shapes on learning with Shape A and subsequent learning with Shape B was examined.

Main Results:

• Blocking of spatial learning was observed when Shape A was initially trained with irrelevant auxiliary shapes.
• No blocking was apparent when Shape A was trained without auxiliary shapes.
• The presence of irrelevant contextual cues during initial training is crucial for the blocking effect.

Conclusions:

• Spatial learning shares similarities with other forms of contingency learning.
• The results suggest the operation of a specialized geometric module in spatial cognition.
• Discrimination learning can lead to changes in attentional processes affecting spatial learning.
