“…The design of Experiment 1 used comparisons both between and within groups of subjects to show whether earthworms could "learn" to go to a particular side of a T maze. Earthworm T-maze studies by other investigators (Aranda et al, 1968;Arbit, 1957Arbit, , 1964Bharucha-Reid, 1956;Datta, 1962;Heck, 1920;James & Woodruff, 1965;Krivanek, 1956;Robinson, 1953;Schmidt, 1955;Swartz, 1929;Zellner, 1966) that showed "learning" included no control groups to show which variables are important to that learning. Although the presence or absence of chemical cues is probably the most important confounding variable, it is not the only one that must be considered.…”

Lumbricus terrestris and Diplocardia riparia appeared to learn to turn either right or left in a T maze containing coelomic fluid deposited during previous trials. When these chemical cues were not present, no evidence of learning was found. The coelomic fluid of L. terrestris was found to be an attractant to conspecifics; that of D. riparia was found to be a repellent. The mucus of both species did not appear to have pheromonal properties.x This study is excerpted from a master's thesis done by the first author under the direction of the second. We thank Paula J. Rosenkoetter and G. E. Gates for their generous advice.2 Requests for reprints should be sent to J.

“…There is now a long tradition of research in comparative psychology indicating that earthworms learn a left or right turn response in T mazes (Aranda, Fernandez, Celume, & Luco, 1968;Arbit, 1957Arbit, , 1964Bharucha-Reid, 1956;Datta, 1962;Heck, 1920;James & Woodruff, 1965;Krivanek, 1956;Robinson, 1953;Schmidt, 1955;Swartz, 1929;Zellner, 1966).…”

“…In addition, these studies have met with indifferent successes (Bharucha-Reid, 1956, andJames andWoodruff, 1965). No reports of approach learning by species of leeches have been found.…”
