Comparing excitatory backward and forward conditioning

Three Pavlovian lick suppression studies with rats were conducted to compare the role of the conditioning context in excitatory backward and forward conditioning. The experiments explored the possibility that excitatory backward conditioning, but not forward conditioning, is mediated by the context. That is, in excitatory backward conditioning, the conditioning context may function as an excitatory mediator, which supports second-order conditioning of the target cue. This possibility contrasts with traditional accounts, which suggests that common processes underlie excitatory backward and forward conditioning. Experiment 1 found that conditioned responding following backward conditioning was attenuated as a result of posttraining extinction of the training context, but the same manipulation elevated responding after forward conditioning. Experiments 2 and 3 found that posttraining and pretraining associative inflation of the context (presenting unsignalled USs) increased conditioned responding to the target of a backward conditioning procedure but either had no effect or reduced responding to the target of a forward conditioning procedure. Thus, excitatory backward and forward conditioning appear to differ in their dependence on the status of the conditioning context.     

THE SPIRIT OF DEMOCRACY AND THE RHETORIC OF EXCESS

If militarism violates the ideals of liberty and justice in one way, and rapidly increasing social stratification violates them in another, then American democracy is in crisis. A culture of democratic accountability will survive only if citizens revive the concerns that animated the great reform movements of the past, from abolitionism to civil rights. It is crucial, when reasoning about practical matters, not only to admit how grave one's situation is, but also to resist despair. Therefore, the fate of democracy depends, to some significant degree, on how we choose to describe the crisis. Saying that we have already entered the new dark ages or a post‐democratic era may prove to be a self‐fulfilling prophecy, because anyone who accepts this message is apt to give up on the hard work of organizing and contestation that is needed to hold political representatives accountable to the people. This paper asks how one might strike the right balance between accuracy and hope in describing the democracy's current troubles. After saying what I mean by democracy and what I think the current threats to it are, I respond to Romand Coles's criticisms of reservations I have expressed before about rhetorical excess in the works of Stanley Hauerwas, Alasdair MacIntyre, and Richard Rorty. This leads to a discussion of several points raised against me by Hauerwas. A digression offers some of my reasons for doubting that John Howard Yoder's biblical scholarship vindicates Hauerwas's version of pacifism. The paper concludes by arguing that Sheldon Wolin's work on the evisceration of democracy, though admirably accurate in its treatment of the dangers posed by empire and capital, abandons the project of democratic accountability too quickly in favor of the romance of the fugitive.     

MOTIVATING STAFF PERFORMANCE IN AN OPERANT LEARNING PROGRAM FOR CHILDREN

Staff performance in a residential child-treatment facility was measured by counting the number of jobs completed and number of new procedures implemented within one week of their assignment. Public notices were posted listing each staff member's duties and new procedures to be implemented during the week. The notices produced an immediate increase in performance levels, which quickly tapered off. Staff members were then given tokens worth $1.00 each for performing jobs and implementing procedures within one week of assignment. The tokens regained and sustained high levels of performance when used in conjunction with the public notices. The use of public notices alone and tokens alone maintained better performance than baseline levels, but neither was as effective in starting and maintaining high-performance levels as was the combined use of the two.     

Sex-role socialization and employment realities: Implications for vocational interest measures

Methods for reporting vocational interests which do and do not reflect sex-role stereotypes are examined. Interest inventory validation procedures based on the prediction of occupational preference and group membership are shown to favor inventories providing scores that reflect past sex-role stereotypes and current employment inequities. Reporting and validation procedures minimizing these shortcomings are suggested. These procedures, which are supported by past practice and recent research, result in similar interest score distributions for men and women. Finally, career counseling problems arising from the confounding of reports of human interests with current employment realities are discussed.
