NATURALISTIC METHODOLOGY IN AN EMERGING SCIENTIFIC PSYCHOLOGY: LOTZE AND FECHNER IN THE BALANCE

The development of a methodologically naturalistic approach to physiological and experimental psychology in the nineteenth century was not primarily driven by a naturalistic agenda. The work of R. Hermann Lotze and G. T. Fechner help to illustrate this claim. I examine a selected set of central commitments in each thinkers philosophical outlook, particularly regarding the human soul and the nature of God, that departed strongly from a reductionist materialism. Yet, each contributed significantly to the formation of experimental and physiological psychology. Their work was influenced substantively by their respective philosophical commitments. Nevertheless, the evaluation of the merits of their specific proposals, Fechner's psychophysics and Lotze's local sign hypothesis respectively, did not depend upon sharing their metaphysical views regarding the human soul or the nature of God. A moderate, but significant, distinction between the contexts of discovery and of justification aids in understanding this balancing act.     

Rigidity in social and emotional memory in the R6/2 mouse model of Huntington's disease

Four experiments were conducted to examine social and emotional memory in the R6/2 transgenic mouse model of Huntington’s disease. First, R6/2 mice were tested in a social transmission of food preference task where they had to acquire a preference for a flavoured food (acquisition) and subsequently to learn a preference for a different flavour (shifted reinforcement). R6/2 mice performed well in the acquisition trial. However, they were impaired in the shifted reinforcement trial and perseverated on the first preference learned. Second, mice were trained in an inhibitory avoidance paradigm, with either one or two footshocks delivered during the training. WT mice given one footshock showed retention levels lower than those of mice trained with two footshocks. By contrast, there was no difference in retention levels of R6/2 mice given either one or two footshocks. Third, mice were tested in an active avoidance task that paired a mild footshock with a warning light. R6/2 mice had a strong age-dependent deficit in this task. Finally, mice were tested in a conditioned taste aversion task that paired a saccharine solution with a nausea-inducing agent (LiCl). R6/2 mice displayed normal aversion, however this was not extinguished following repeated exposure to saccharine solution alone. Our data show that while R6/2 mice have functional hippocampus-based memory, they have deficits in striatum-based memory skills. Further, social and emotional memories appear to be encoded in a rigid way that is not influenced by subsequent learning or by arousal levels.     

La répression émotionnelle et son rôle en psychopathologie

In the context of studies on mechanisms of emotional treatment and regulation in affective blunting, this paper focalizes on those whose objective is to disminish awareness of subjective emotional experience. The cognitive mechanism of repression is first presented, defined as a coping strategy which, used in a habitual way, is conceptualised as a personality dimension. Its role on the whole panel of emotional components and the researches on its underlying cognitive mechanisms, in particular those which may explain the observed memory deficits for negative emotional events, are developed. The paper also presents models of maturation of emotional awareness, differentiating several hypothetic ways of emotional treatment which determine specific emotional subjective experiences. In regard of studies which have explored these modes of emotional treatment in alexithymia, hypotheses on their role in the blunting of affect process and on the quality of subjective experience are proposed.     

EDUCATION SECTION: Infant observation in Britain:The Tavistock approach

The author draws attention to something distinctive in the psychoanalytic 'air' from the early 1960s onwards: the strong emphasis upon the very early psychological, emotional and cognitive view of infants and young children. She focuses on the work of two analysts in particular, Esther Bick and Wilfred Bion, and the comparable, though differently expressed, centrality of the observational method in their work. Each explored not only the pathological picture but also the nature and integrative function of psychic containment in earliest mental life. Each also shared a preoccupation with what constituted a psychoanalytic attitude and with the process of becoming a psychoanalyst and, in Bick's case, a child analyst or psychotherapist. The author provides an historical background to the idea of observation, followed by an account, with detailed examples, of the nature of infant observation and the observational method as taught and practised at the Tavistock Clinic, London since the late 1940s, and subsequently in many other training institutions. Here the themes of Bick and Bion are constantly interrelated such that the prototype or model for the creation of emotional meaning and thought can be appreciated and learning from experience can take place.     

Augustine’s <Emphasis Type="Italic">Confessions</Emphasis>: The Story of a Divided Self and the Process of Its Unification

This article takes up William James’ observation that Saint Augustine is “a classic example” of the discordant personality or divided self, and employs E. R. Dodd’s equally classic (1927–28) article on Augustine’s “spiritual maladjustment” to explore the psychological bases, especially parental, for Augustine’s discordant personality, and to evaluate the effectiveness of Augustine’s efforts to overcome the discordancy through a personal religious conversion.     

Creating the Best Possible World: Some Problems from Parfit

It is sometimes argued that if God were to exist, then the actual world would be the best possible world. However, given that the actual world is clearly not the best possible world, then God doesn’t exist. In response, some have argued that the world could always be improved with the creation of new people and that there is thus no best possible world. I argue that this reasoning gives rise to an instance of Parfit’s mere addition paradox and should thus be rejected. Others (Robert Adams, in particular) have argued that the actual world may, in fact, be the best possible world, at least for all actual people. I argue that this reasoning gives rise to Parfit’s non-identity problem and should thus be rejected.

Rate changes in the speech of stutterers after therapy

The fluent speaking rate of nine adult male stutterers was compared before and after stuttering intervention. The subjects, ranging in age from 18 to 37 yr (mean, 25 yr, 3 mo), exhibited mild to severe stuttering prior to treatment. The only rate reduction strategy taught to subjects during intervention was to slow the first phoneme or syllable of sentences spoken. In addition, however, subjects significantly reduced their overall rate as determined by measurements made of their fluent speech at the middle of sentences, as well as overall sentence durations (excepting the first word of utterances). The data from this investigation are interpreted relative to the facilitation/simplification hypothesis.     

Developmental changes in predicting one's own span of short-term memory

Developmental changes in the accuracy of predicting one's own recall were studied, using preschool, third grade, and college subjects in Experiment 1 and third grade and college subjects in Experiment 2. Experiment 1 showed that prediction accuracy increased from the preschool to the college years, subjects were not influenced by a potential “expectancy” bias in the procedure, and only third grade subjects were influenced by the presence of norms about peer performance. Experiment 2 showed that third graders and college subjects lower their predictions in the face of “false” norm information, with college subjects being the only group to under predict actual recall in both experiments. Thus, although adults are significantly more accurate than elementary shool children in estimating short-term recall, their susceptibility to norm information suggests that even they have uncertainty about their exact capabilities.
