Effect of variable-interval punishment on the behavior of humans in variable-interval schedules of monetary reinforcement

One male and three female human subjects pressed a button for monetary reinforcement under a range of variable-interval schedules specifying different frequencies of reinforcement. On alternate days, responding was also punished (by subtraction of money) according to a variable-interval 170-second schedule. In the absence of punishment, the rate of responding was an increasing negatively accelerated function of reinforcement frequency, as predicted by Herrnstein's equation. The effect of the punishment schedule was to suppress responding under lower frequencies of reinforcement; responding under higher reinforcement frequencies was much less affected. This was reflected in an increase in the value of K_H (the constant expressing the reinforcement frequency corresponding to the half-maximal response rate), whereas there was no significant change in the value of R_max (the constant expressing the maximum response rate). Previous results had shown that variable-ratio punishment resulted in a change in the values of both constants (Bradshaw, Szabadi, and Bevan, 1977). The results of the present study were consistent with the concept that the suppressive effects of punishment on responding depend on the nature of the punishment schedule.     

Effect of punishment on human variable-interval performance

Three female human subjects pressed a button for monetary reinforcement in a range of variable-interval schedules specifying different frequencies of reinforcement. On alternate days, responding was also punished (by subtracting money) according to a variable-ratio 34 schedule. In the absence of punishment, rate of responding was an increasing negatively accelerated function of reinforcement frequency; the relationship between response rate and reinforcement frequency conformed to Herrnstein's equation. The effect of the punishment schedule was to suppress responding at all frequencies of reinforcement. This was reflected in a change in the values of both constants in Herrnstein's equation: the value of the theoretical maximum response-rate parameter was reduced, while the parameter describing the reinforcement frequency corresponding to the half-maximal response rate was increased.     

Manipulations in argumentation

In public and political practice, argumentation involves verbal manipulations, which have not been sufficiently studied in modern argumentation theory. This paper proposes to analyse such manipulations as speech acts, by means of the pragmadialectical theory of argumentation.     

The Correspondence between Human Intelligibility and Physical Intelligibility: The View of Jean Ladrière

This article seeks to explain the correspondence between human intelligibility and that of the physical world by synthesizing the contributions of Jean Ladrière. Ladrière shows that the objectification function of formal symbolism in mathematics as an artificial language has operative power acquired through algorithm to represent physical reality. In physical theories, mathematics relates to observations through theoretic and empirical languages mutually interacting in a methodological circle, and nonmathematical anticipatory intention guides mathematical algorithmic exploration. Ladrière reasons that mathematics can make the physical world comprehensible because of the presence of a rational principle in both kinds of intelligibility.     

Audiences,relevance, and cognitive environments

This paper discusses the fundamental sense in which the components of an argument should be relevant to the intended audience. In particular, the evidence advanced should be relevant to the facts and assumptions that are manifest in the cognitive environment of the audience. A version of Sperber and Wilson's concept of the cognitive environment is applied to argumentative concerns, and from this certain features of audience-relevance are explored: that the relevance of a premise can vary with the audience; that irrelevant premises can be made relevant; that evidence can be relevant by degrees; and that this notion of relevance will assist the argumentation analyst in the identification and assessment of hidden premises.     

Differences in attitudes towards inclusion between parents of children with and without disabilities

IntroductionInclusion is among the greatest challenges facing educational systems throughout the world today. Parents’ attitudes play a key role in the successful implementation of inclusion. Therefore, there is a growing interest in comparing the attitudes towards inclusion among parents of children with and without disabilities.ObjectiveThe current study was set out to assess if there are differences in attitudes towards inclusion between parents of children with and without disabilities.MethodThe sample consisted of 332 parents (127 parents of children with disabilities and 205 parents of children without disabilities). All children attended general education primary schools. Participants completed anonymously the Greek version of Attitude Survey Towards Inclusive Education – Parents (de Boer et al., 2012a, b).ResultsThe findings showed no significant differences in attitudes towards inclusion between parents of children with and without disabilities. However, significant differences were found in parents’ attitudes towards inclusion based on their familiarity with a disabled person and the type of disabilities (congenital or acquired).ConclusionThese findings highlight the need to take into consideration parents’ and children's factors during the development of interventions to change attitudes towards inclusion.     

Theistic Dissonance Among Religious Jewish Holocaust Survivors: A Psychodynamic Perspective

Coining the term theistic dissonance to capture conflicted attitudes and feelings toward God, this article examines faith-based reactions to the Holocaust. The theological weltanschauung of religious Jewish Holocaust survivors is analyzed, with a particular focus on their attempts to reconcile the notion of a benevolent and caring God with their harrowing experience. Basic religious sources and contemporary literature are presented to elucidate the realm of resolutions of theistic dissonance. It is suggested that elements of defense mechanisms are adapted from the emotional into the cognitive realm, and are used by survivors to facilitate respective interpretations of God’s role during the Holocaust. Dissonance resolution is seen as being informed theologically and experientially for these victims who confronted stark challenges to their religious integrity.     

‘Naturally More Vehement and Intense’: Vehemence in Calvin's Sermons on the Lord's Supper

This article focuses on the remarks of Conrad Badius – in the preface to his publication of Plusieurs sermons of Calvin's – about the ‘vehemence’ of sermons relating to the Lord's Supper. By comparing two of Badius's prefaces in editions of Calvin's sermons, it becomes clear that he chose his words intentionally. On examining here the rhetorical background of vehementia/véheménce, its use in the final part of Calvin's sermons is clarified. Some contemporary witnesses to Calvin's habit are cited. Moreover, in light of the role of vehemence in Calvin's preaching in general, it is shown that the context of the preparation for the sacrament and its celebration prompted Calvin to preach even more vigorously. The outcome is that Badius's comments on Calvin's preaching underline the vital importance of the Lord's Supper for the Reformer, a sacrament which required intensive and sanctifying preparation.
