Table 1.

Assumptions underlying the path integration mechanism that would result in each of hypothetical foraging/homing paths illustrated inFig. 2 

Hypothetical pathDirection informationIntegration of self-translation during disk rotation?Integration of imposed translation resulting from disk rotation?Integration of compensatory turns?
Black Allothetic No No No; direction from e.g. sky 
Blue Allothetic Yes; measured against e.g. sky No No; direction from e.g. sky 
Violet Allothetic Yes; measured against e.g. sky Yes; measured against e.g. sky No; direction from e.g. sky 
Red Idiothetic No No No 
Orange Idiothetic No No Yes 
Green Idiothetic Yes; measured against body axis No Yes 
Gray Idiothetic Yes; measured against body axis No No
