REPLACING MALADAPTIVE SPEECH WITH VERBAL LABELING RESPONSES: AN ANALYSIS OF GENERALIZED RESPONDING

We taught three mentally handicapped students to answer questions with verbal labels and evaluated the generalized effects of this training on their maladaptive speech (e.g., echolalia) and correct responding to untrained questions. The students received cues-pause-point training on an initial question set followed by generalization assessments on a different set in another setting. Probes were conducted on novel questions in three other settings to determine the strength and spread of the generalization effect. A multiple baseline across subjects design revealed that maladaptive speech was replaced with correct labels (answers) to questions in the training and all generalization settings. These results replicate and extend previous research that suggested that cues-pause-point procedures may be useful in replacing maladaptive speech patterns by teaching students to use their verbal labeling repertoires.     

The evolution of policy arguments in teachers' negotiations

Argument is a critical component in policy deliberations. In this study, negotiation is viewed as a type of policy deliberation, one characterized by attack and defense of proposals, interdependence between disputants, and mixed motives of cooperation and competition. Argument in negotiation, then, functions as a reason-giving activity to enact policy. Employing a category system based on rhetorical stasis, the researchers examine whether bargainers specialize in their use of argument types and whether this specialization remains consistent throughout a teacher-school board negotiation and whether it differs for the type of settlement of agenda items. Results of the study suggest that bargainers specialize in argument types at different times during the bargaining. In the early stages of negotiation, teachers center on harm and workability arguments to prepare their case and justify the merits of their proposals, but in the latter phases of bargaining they switch to arguments on implementation to reaffirm their demands and to prioritize issues. Board members, in the early stages, rely on disadvantage, workability, and implementation arguments to establish resistance points and to refute appeals for change, but in the latter stages of negotiation they employ harm-inherency and disadvantage arguments to weigh the costs of concessions and to rationalize the settlement. This study, then, supports the existence of phase variation in bargaining and argues for a developmental approach in deciphering how negotiators who hold antithetical positions reach mutually satisfactory settlements.     

Animal models of source memory

Source memory is the aspect of episodic memory that encodes the origin (i.e., source) of information acquired in the past. Episodic memory (i.e., our memories for unique personal past events) typically involves source memory because those memories focus on the origin of previous events. Source memory is at work when, for example, someone tells a favorite joke to a person while avoiding retelling the joke to the friend who originally shared the joke. Importantly, source memory permits differentiation of one episodic memory from another because source memory includes features that were present when the different memories were formed. This article reviews recent efforts to develop an animal model of source memory using rats. Experiments are reviewed which suggest that source memory is dissociated from other forms of memory. The review highlights strengths and weaknesses of a number of animal models of episodic memory. Animal models of source memory may be used to probe the biological bases of memory. Moreover, these models can be combined with genetic models of Alzheimer's disease to evaluate pharmacotherapies that ultimately have the potential to improve memory.     

CONFESSIONS OF A LATE‐BLOOMING, “MISEDUCATED” PHILOSOPHER OF SCIENCE

This article provides a survey of Walker Percy's criticism of what Pope Benedict XVI calls “scientificity,” which entails a constriction of the dynamic interaction of faith and reason. The process can result in the diminishment of ethical considerations raised by science's impact on public policy. Beginning in the 1950s, Percy begins speculating about the negative influence of scientificity. The threat of a political regime using weapons of mass destruction is only one of several menacing developments. The desacrilization of human life from cradle to grave leads Percy to assert that modern science's impact is often radically incoherent. In The Moviegoer, Percy finds his existential and theistic voice that would enable him to advance his critique of science.     

Argumentative Text as Rhetorical Structure: An Application of Rhetorical Structure Theory

Rhetorical Structure Theory (RST), as a tool for analyzing written texts, is particularly appropriate for analyzing argumentative texts. The distinction that RST makes between the part of a text that realizes the primary goal of the writer, termed nucleus, and the part that provides supplementary material, termed satellite, is crucial for the analysis of argumentative texts.The paper commences by determining the concept of argument relation (argument + conclusion) and by briefly presenting RST. It continues by identifying five of RST's rhetorical relations of the satellite/nucleus schema (Evidence, Motivation, Justify, Antithesis, Concession) as five argument relations, each being, logically or pragmatically, a special kind of argument: Evidence being a supportive argument, Motivation an incentive argument, Justify a justifier argument, and Antithesis and Concession persuader arguments. To illustrate, an analysis of three short texts concludes the paper.     

Sequences of spaced responses: Behavioral units and the role of contiguity

Sequences of temporally spaced responses were reinforced to investigate the effects of delay of reinforcement on the formation of functional behavioral units. In Experiment 1, rats' two- and three-response demarcated sequences of left and right lever presses were reinforced such that different response distributions would occur depending on whether the sequences themselves or individual responses were functional units. The matching law could thus be obeyed either by individual responses or by sequences, but not by both; intermediate results were possible. Both regular (nonretractable) and retractable levers were used; the retractable levers precluded the occurrence of insufficiently spaced responses. At a minimum interresponse time of 5 s for regular levers and 7 s for retractable ones, matching results were intermediate, with greater evidence of sequence conditionability in the two-response sequences than in the three-response sequences. In Experiment 2, the required minimum interresponse spacing for two-response retractable-lever sequences was varied in an attempt to locate the sequence matching threshold. This attempt was unsuccessful, but the sequences (instead of individual responses) more closely obeyed the matching law. In the shortest spaced condition, conditional probability data on Lag 1 sequence emission order showed marked, highly similar patterning for all rats, indicating sequential control of the sequences. Post hoc definition of the behavioral unit in these studies is ambiguous. Although reinforcement contiguity was important, aspects of the results could support both molar- and molecular-level interpretations.     

Begging what is at issue in the argument

This paper objects to treating begging the question as circular reasoning. It argues that what is at issue in the argument is not to be confused with the claim or position that the arguer is adopting, and that logicians from Aristotle on give the wrong definition and have difficulty making sense of the fallacy because they try to define it in terms of how an argument is defined by logical theory - as a sequence consisting of premises followed by a conclusion. That the problematic about begging the question depends on treating an argument as a context-less sequence of statements seems to be anticipated by the pragma-dialectical approach. The paper offers a critique of this dialogical approach, as exemplified by Douglas Walton in his recent book on begging the question, on the grounds that it raises more problems than it solves. It concludes with the suggestion that what is really at issue in discussions of begging the question is the need for a theory of fallacy.     

Contexts of Begging the Question

In this paper a dialogical account of begging the question is applied to various contexts which are not obviously dialogues: - reading prose, working through a deductive system, presenting a legal case, and thinking to oneself. The account is then compared with that in chapter eight of D. Walton'sBegging the Question (New York; Greenwood, 1991).     

Reductionism in Fallacy Theory

(1) The aim of the paper is to develop a reduction of fallacy theory, i.e. to 'deduce' fallacy theory from a positive theory of argumentation which provides exact criteria for valid and adequate argumentation. Such reductionism has several advantages compared to an unsystematic action, which is quite usual in current fallacy but which at least in part is due to the poor state of positive argumentation theory itself. (2) After defining 'fallacy' (3) some principle ideas and (4) the exact criteria for (argumentatively) valid and adequate arguments of the 'practical theory of argumentation' of the author are expounded. These criteria will be used as the positive basis for the following reduction. (5) In the main part of the paper a systematization, definition and explanation of the main types and many subforms of fallacies of argumentative validity and (6) adequacy is developed, following the list of positive conditions of validity and adequacy. In addition to many new types of fallacies, this systematization contains the most important of the traditionally known and named fallacies; these are explained and the criteria for some of them are corrected or put more precisely.
