On the irreducibility of the will

This paper criticizes the thesis that intending to do something is reducible to some combination of beliefs and desires. Against Audi's recent formulation of such a view I offer as counterexample a case wherein an agent who wants and expects to V has not yet decided whether to V and hence does not yet intend to. I try to show that whereas belief that one will V is not necessary for intending to V, as illustrated in cases of desperate attempts to V, one cannot intend to V without preferring to V (rather than not V) and thus one cannot intend to V without, in some sense, wanting to V (at least wanting it in preference to not V-ing). The connection of one's intentions with one's objectives, attempts, plans, and hopes is briefly treated, and some influential work by Davidson is criticized.     

Some remarks on “ambiguity” and “perceptual processes”

A paper by Bever, Garrett, and Hurtig on the perception of ambiguous sentences is analyzed in terms of (1) the explanation offered for the experimental findings, (2) the linguistic theory underlying the experiment, and (3) the characteristics of the stimuli utilized. It is concluded that Bever, Garrett, and Hurtig's findings are open to serious question, particularly because of multiple deficiencies in the design of the experiment.     

Improving Delivery Behaviors During Exposure for Pediatric OCD: A Multiple Baseline Training Trial With Community Therapists

This study tested whether a new training tool, the Exposure Guide (EG), improved in-session therapist behaviors (i.e., indicators of quality) that have been associated with youth outcomes in prior clinical trials of exposure therapy. Six therapists at a community mental health agency (CMHA) provided exposure therapy for 8 youth with obsessive–compulsive disorder (OCD). Using a nonconcurrent multiple baseline design with random assignment to baseline lengths of 6 to 16 weeks, therapists received gold-standard exposure therapy training with weekly consultation (baseline phase) followed by addition of EG training and feedback (intervention phase). The primary outcome was therapist behavior during in-session exposures, observed weekly using a validated coding system. Therapist behavior was evaluated in relation to a priori benchmarks derived from clinical trials. Additional outcomes included training feasibility/acceptability, therapist response to case vignettes and beliefs about exposure, and independent evaluator-rated clinical outcomes. Three therapists reached behavior benchmarks only during the EG (intervention) phase. Two therapists met benchmarks during the baseline phase; one of these subsequently moved away from benchmarks but met them again after starting the EG phase. Across all therapists, the percentage of weeks meeting benchmarks was significantly higher during the EG phase (86.4%) vs. the baseline phase (53.2%). Youth participants experienced significant improvement in OCD symptoms and global illness severity from pre- to posttreatment. Results provide initial evidence that adding the EG to gold-standard training can change in-session therapist behaviors in a CMHA setting.     

Réflexions critiques sur les notions d’abolition et d’altération de la faculté à discerner

Inasmuch as the constitution of the mens rea of any offence remains suspended to its integrity, the capacity for discernment represents a condition of accountability whose definition responds to issues that are as much technical – with respect to psychiatric and psychological penal expertise – as they are theoretical – with respect to our conception of criminal responsibility and the psychological prerequisites that underlie it. Now, the fact is that since its introduction in 1992 with article 122–1 of the Penal Code, this notion of discernment is characterized by a certain conceptual inconsistency, giving rise to a damaging plurality of meanings making the verb discern the condensed version of a heterogeneous network of distinct psychological functions. The polysemic term of discernment thus gives rise to a fundamental indetermination as to the nature of the faculty that must be examined in order to decide on its abolition or its preservation at the moment of the act. This is not without favouring the appearance and persistence of arbitrary interpretations, and consequently discordant expert conclusions. Even more problematic, however, is the idea of an alteration of discernment, given the irreducible discrepancy between the continuous nature of an alteration and the discontinuous nature of the conclusion to which the agent is subject, in that the legal demand requires a decision – in a discretization of what is continuous – between the presence and absence of something that is lacking. We will in fact show in what way this concept of alteration as it applies to discernment tends to be either meaningless, or redundant – and therefore useless – in relation to that of abolition. So much so that the only conceivable solution to maintain a certain gradation of degrees of non-accountability seems to consist in having to specify the different types of abolition of discernment potentially observed, and then to propose a hierarchization according to their greater or lesser compatibility with the conservation of a criminal responsibility. .     

Resolution of dilemmas: A mathematical theory

A mathematical formulation for a dilemma (i.e. a situation in which a very difficult choice between two alternatives must be made) is given. Multiple-objective programming is assumed as the model for a single decision maker. It is shown that, in principle, any dilemma is resolvable. Furthermore, there is always more than one way in which to resolve a dilemma. Illustrative examples from non-convex optimization are presented.     

Regression II. Development through regression

As shown in our previous paper (‘Regression I. Experimental approaches to regression’, JAP, 65, 2, 345-65), the common mechanism of regression can be described as reversible dedifferentiation, which is understood as a relative increase of the proportion of low-differentiated (older) systems in actualized experience. Experimental data show that regression following disease (chronic tension headache) is followed by adaptation and an increase in system differentiation in that experience domain which contains systems responsible for that adaptation. The results of mathematical modelling support the idea that reversible dedifferentiation can be one of the mechanisms for increasing the effectiveness of adaptation through learning. Reversible dedifferentiation, which is phenomenologically described as regression, is a general mechanism for restructuring the organism-environment interactions in situations where behaviours that were effective in the past become ineffective. Reversible dedifferentiation has evolved as a component of adaptation when new behaviours are formed and large-scale modifications in the existing behaviours are required in the face of changes in the external and/or internal environment. Thus, the authors believe that this article provides evidence for Jung’s view that regression is not only a ‘return’ to past forms of thinking, affects and behaviour, but that regressive processes provide a significant impetus for psychological growth and development.     

Age-Specific Effects of Lexical–Semantic Networks on Word Production

The lexical–semantic organization of the mental lexicon is bound to change across the lifespan. Nevertheless, the effects of lexical–semantic factors on word processing are usually based on studies enrolling young adult cohorts. The current study aims to investigate to what extent age-specific semantic organization predicts performance in referential word production over the lifespan, from school-age children to older adults. In Study 1, we conducted a free semantic association task with participants from six age-groups (ranging from 10 to 80 years old) to compute measures that capture age-specific properties of the mental lexicon across the lifespan. These measures relate to lifespan changes in the Available Richness of the mental lexicon and in the lexical–semantic Network Prototypicality of concrete words. In Study 2, we used the collected data to predict performance in a picture-naming task on a new group of participants within the same age-groups as for Study 1. The results show that age-specific semantic Available Richness and Network Prototypicality affect word production speed while the semantic variables collected only in young adults do not. A richer and more prototypical semantic network across subjects from a given age-group is associated with faster word production speed. The current results indicate that age-specific semantic organization is crucial to predict lexical–semantic behaviors across the lifespan. Similarly, these results also provide cues to the understanding of the lexical–semantic properties of the mental lexicon and to lexical selection in referential tasks.
