Propositional quantifiers

Summary In discussing propositional quantifiers we have considered two kinds of variables: variables occupying the argument places of connectives, and variables occupying the argument places of predicates.We began with languages which contained the first kind of variable, i.e., variables taking sentences as substituends. Our first point was that there appear to be no sentences in English that serve as adequate readings of formulas containing propositional quantifiers. Then we showed how a certain natural and illuminating extension of English by prosentences did provide perspicuous readings. The point of introducing prosentences was to provide a way of making clear the grammar of propositional variables: propositional variables have a prosentential character — not a pronominal character. Given this information we were able to show, on the assumption that the grammar of propositional variables in philosopher's English should be determined by their grammar in formal languages (unless a separate account of their grammar is provided), that propositional variables can be used in a grammatically and philosophically acceptable way in philosophers' English. According to our criteria of well-formedness Carnap's semantic definition of truth does not lack an essential predicate - despite arguments to the contrary. It also followed from our account of the prosentential character of bound propositional variables that in explaining propositional quantification, sentences should not be construed as names.One matter we have not discussed is whether such quantification should be called propositional, sentential, or something else. As our variables do not range over (they are not terms) either propositions, or sentences, each name is inappropriate, given the usual picture of quantification. But we think the relevant question in this context is, are we obtaining generality with respect to propositions, sentences, or something else?Because people have argued that all bound variables must have a pronominal character, we presented and discussed in the third section languages in which the variables take propositional terms as substituends. In our case we included names of propositions, that-clauses, and names of sentences in the set of propositional terms. We made a few comparisons with the languages discussed in the second section. We showed among other things how a truth predicate could be used to obtain generality. In contrast, the languages of the second section, using propositional variables, obtain generality without the use of a truth predicate.Special thanks are due to Nuel D.

Terminations

Whether the person leaving the group is a group member or a group therapist, the basic dynamics of separation are the same, involving the separation process as well as mourning. Terminations evoke ambivalent feelings of both separation-pain and hope. Group members and the departing person experience a loss, which reminds them of other losses, and the departing person (group member or therapist) may also experience some guilt. Any termination will have an effect on the-group-as-a-whole, as well as on the individual members, and must be dealt with prior to the actual leaving, as well as after the termination.     

Acting out in group psychotherapy

Acting out is a common occurrence in group psychotherapy. After a brief review of relevant psychoanalytic and group psychotherapy literature, this paper presents various kinds of acting out by the individual group members and the handling of such acting out by the therapist, discusses acting out by the group as a whole, and gives a brief overview of acting out by the group therapist. Specific examples are given of acting out and ways of dealing with it.     

AN ANALYSIS OF SOME VARIABLES INFLUENCING THE EFFECTIVENESS OF REPRIMANDS

Although several studies have shown that social reprimands can function as punishers, no study reported to date has isolated any of the factors influencing reprimand efficacy. Three experiments were conducted to investigate several factors. Experiment 1 used an alternating treatments design and was conducted on two elementary school boys, one of whom was in a special education class. Results showed that verbal reprimands delivered with eye contact and firm grasp of the student's shoulders reduced disruptive behavior to a greater extent than did verbal reprimands delivered without eye contact and grasp. Both types of reprimand were more effective than a baseline condition during which disruptive behavior was ignored. Experiment 2 also used an alternating treatments design and was conducted on one elementary school boy. Results demonstrated that reprimands delivered from one meter away were considerably more effective than reprimands delivered from seven meters away. Experiment 3 used a reversal design and was conducted on two pairs of elementary school children, one a pair of boys and the other a pair of girls. Results demonstrated that reprimands delivered to just one member of the pair reduced the disruptive behavior of both members of the pair. Thus, the effects of reprimands “spilled” over to nonreprimanded students.     

Family systems and the attachment dynamic

Using attachment theory as a theoretical framework, the concept of the attachment dynamic is introduced as a model to explain (1) how individual members of a family behave as though they constituted a system (2) the extent to which the complementary activities of attachment and care-giving behaviour (a) govern the movements of family members towards or away from each other; (b) affect the degree to which they each engage in creative exploratory activities; and (c) influence the internal representation each family member builds of him or herself in action with others or acting alone. The attachment dynamic is considered to be played out in many forms which range along a continuum from highly adaptive to grossly maladaptive. The characteristics of effective care-giving behaviour, adaptive attachment behaviour and exploratory behaviour, integrated within adaptive forms of the attachment dynamic, are contrasted with ineffective care-giving, continuing unassuaged attachment behaviour and anxious, frustrated or inhibited exploratory behaviour which are found in maladaptive forms of the dynamic. The implications of this model for family therapy are outlined.     

An analysis of the behaviour of day- and night-wetting children: Towards a model of micturition control

Recent research has suggested that features of daytime bladder control are of importance in predicting the treatment response of nocturnal enuretics to the enuresis alarm. This paper suggests that a detailed analysis of daytime toileting behaviour should be carried out. A study is described where 22 children with day and night wetting and 22 matched normal controls were observed after they had consumed a considerable amount of fluid. The limb movements and postures were reliably rated by two observers and wetting events and visits to the toilet were recorded. Various deficits in bladder control were shown by the enuretic children. A working model of daytime bladder control is described which draws attention to significant components which may be disturbed in abnormal bladder control. The models implies that treatment regimes should be based upon a behavioural analysis of the particular dysfunction shown by the enuretic child.     

Bayesian inference and the classical test theory model: Reliability and true scores

A general one-way analysis of variance components with unequal replication numbers is used to provide unbiased estimates of the true and error score variance of classical test theory. The inadequacy of the ANOVA theory is noted and the foundations for a Bayesian approach are detailed. The choice of prior distribution is discussed and a justification for the Tiao-Tan prior is found in the particular context of the “n-split” technique. The posterior distributions of reliability, error score variance, observed score variance and true score variance are presented with some extensions of the original work of Tiao and Tan. Special attention is given to simple approximations that are available in important cases and also to the problems that arise when the ANOVA estimate of true score variance is negative. Bayesian methods derived by Box and Tiao and by Lindley are studied numerically in relation to the problem of estimating true score. Each is found to be useful and the advantages and disadvantages of each are discussed and related to the classical test-theoretic methods. Finally, some general relationships between Bayesian inference and classical test theory are discussed.
