Two aspects of the reliability of the hole-board apparatus were investigated—the similarity between scores of different samples of the same population on their first exposure to the apparatus, and the test-retest reliability. Rats and mice were given a 5-min exposure to the hole-board and then retested for 5 min after 1, 2 or 8 days.

Male rats and mice showed good initial exposure reliability, whereas the female mouse groups differed significantly. All animals showed a positive test-retest correlation (range 0.31–0.78), but a homogeneous group (e.g. all animals habituating) produced higher correlations (range 0.60–0.99).

Comparison of scores on the two 5-min exposures showed that not all groups showed significant habituation, but the animals exposed to the hole-board for two 10-min periods showed both significant habituation and test-retest reliability.

This work was conducted whilst in receipt of a Roche Research Fellowship, and on leave of absence from the City of London Polytechnic.
