A simple circuit for a digital millisecond timer and event counter is described. The total cost of the unit including all components, a power supply, and an enclosure is less than $30. Daily use in simple reaction time experiments has demonstrated the reliability of the design. 相似文献

An inexpensive (less than $35) solid food reinforcement dispenser was developed using commercially available parts for commonly found vending machines. This device proved to be reliable and efficient in repeated use with laboratory primates in a video task testing situation. 相似文献

An electric retraction mechanism, which is adaptable to a wide range of operant manipulanda, was developed. Miniaturized, inexpensive toy railroad equipment was used to simplify construction. The mechanism, utilized as a retractable rat lever, has operated reliably and uniformly over a range of independent retraction and extension times. 相似文献

A low-cost sound pattern generator that is remotely programmable has been developed to produce pure-tone auditory patterns. The device, which is compatible with relay programming equipment, can generate either of two auditory patterns in the sequence ABA or BAB. The generator features an independently settable range of ON and OFF durations (0.1 to 1.0 sec) for pure-tone bursts and a selectable range (0.2 to 2.0 sec) of intercycle intervals. The inexpensive construction cost coupled with the flexibility of the timing characteristics of the generator should make it of interest to a wide variety of auditory researchers. 相似文献

An inexpensive (under $600) microcomputer-controlled image analysis system that uses commercially available components is described. Both programming and construction details are provided, as well as a discussion of the utility of the apparatus in studies of animal behavior. The system has been used to record position preferences and activity in animal groupings of various size. Simply by changing the distance between the target and the camera, animals and/or arenas of differing size can be monitored. 相似文献

This article, using a counter as an example, explores a novel approach in constructing a cognitive system. The system is a paired memory system of “left and right brain” consisting of a number of memory units. The “left brain” is dedicated to the cognitive process of symbols, and the “right brain” to the representation of the symbols. The left and right subsystems are connected by bundles of internal communication signals. The paired memory system can learn facts and generalize concepts. Its cognitive capability is realized through the communication among these memory units at different cognitive levels within the system. The key claims in this paper are supported by empirical findings and theoretical principles. An AI counter is built and demonstrated in terms of concept learning and responding. 相似文献
