Fitted model specifications (Study 2).

Model	Fixed effects	Random effects	AIC	BIC	LR test
A	beep-track accuracy	participant (intercept)	5877.3	5897.2	NA
B	same as A	A + track (slope with accuracy)	5657.7	5697.7	χ2(3) = 225.51, $p<0.001$
C	B + displacement direction	same as B	5633.1	5679.6	${\chi }^2\mathrm{(1)}=\mathrm{26.67,}p<0.001$

Note. Likelihood-ratio (LR) tests are each carried with respect to the model in the immediately preceding row, and characterise the extent to which the new model better accounts for the data than the previous model.
