A survey was sent to doctoral school psychologists to determine their research productivity and topical interests. Approximately two thirds of 147 respondents indicated doing some research during ...1974–1975. Studies dealing with topics of assessment and program evaluation were most prevalent. Only about one in five studies was actually published and most of these were in nonprestigious periodicals. Academic school psychologists were more likely to do research and publish than were applied school psychologists. Academic and applied psychologists did not differ in terms of numbers of unpublished written or oral research reports. The correspondence of these results with prior data on school psychology research was noted and suggestions to increase the circulation of research findings are presented.
The effects of temperature on the firing patterns of the excitatory motor supply to the bender muscle were examined in autotomized walking limbs of the crab Pachygrapsus crassipes. A brief electrical ...shock applied to the limb nerve evoked an action potential in one or both of the excitor axons and an excitatory junctional potential (ejp) in the bender muscle fibers. However, at high temperatures a single shock to one of the excitor axons (E2) resulted in a short train of nerve spikes and a concomitant burst of ejps. Extracellular recordings made from two sites along the E2 axon demonstrated that the additional action potentials are generated peripherally. Furthermore, myogram recordings from bender muscles in untethered animals indicate that peripheral generation of spikes does take place in intact crabs exposed to high temperatures. The peripheral generation of action potentials exhibited a critical temperature threshold which could be altered by acclimation and by low levels of ethanol in the saline bathing the autotomized limb preparation. This phenomenon may, therefore, be closely associated with membrane fluidity.
