Semiotic transformations in psychoanalysis with infants and adults

The author addresses issues that emerge when we compare psychoanalytic experiences with adults and with infants. Two analyses-one with a 35 year-old woman and one with a 2 week-old boy and his mother-illustrate that infant psychoanalytic experiences help us understand and handle adult transference. However, we cannot extrapolate infant experiences to adult work. Truly, witnessing the baby's communication widens our sensitivity to non-verbal layers of the adult's communication. Infant work also offers a direct encounter with the container and the contained personified by a mother with her baby. But we need to conceptualize carefully the links between clinical experiences with babies and adults. When we call an adult transference pattern 'infantile', we imply that primeval experience has been transformed into present behaviour. However, if we view the analytical situation as one in which infantile invariants have transformed into adult symptoms, we face the impossible task of indicating the roots of the present symptoms. The author rather suggests that what is transformed is not an invariant infantile essence but signs denoting the patient's inner reality. He proposes we define transformation as a semiotic process instead of building it on an essentialist grounding. If we view the analytic situation as a map of signs that we translate during our psychoanalytic work, we can proceed into defining containment as a semiotic process. This idea will be linked with a conceptualization of the mother-infant relation in semiotic terms.     

Working memory deficit in children with mathematical difficulties: a general or specific deficit?

This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both mathematical and reading difficulties were compared with 47 age-matched and 50 younger controls (9-year-olds) on a number of working memory tasks. Compared with the age-matched controls, both groups of children with MDs performed worse on tasks tapping the central executive (e.g., visual matrix span) and the phonological loop (e.g., word span). More important, the MD group performed worse than the younger controls on the counting span task, whereas the group with comorbid mathematical and reading difficulties performed worse on the counting span task and the visual matrix span task. These findings provide support for the assumption that children with MDs have a working memory deficit. More specifically, children with MDs have a central executive deficit connected to concurrent processing and storage of numerical and visual information.     

Moral Relativism

Moral relativism comes in many varieties. One is a moral doctrine, according to which we ought to respect other cultures, and allow them to solve moral problems as they see fit. I will say nothing about this kind of moral relativism in the present context. Another kind of moral relativism is semantic moral relativism, according to which, when we pass moral judgements, we make an implicit reference to some system of morality (our own). According to this kind of moral relativism, when I say that a certain action is right, my statement is elliptic. What I am really saying is that, according to the system of morality in my culture, this action is right. I will reject this kind of relativism. According to yet another kind of moral relativism, which we may call epistemic, it is possible that, when one person (belonging to one culture) makes a certain moral judgement, such as that this action is right, and another person (belong to another culture) makes the judgement that the very same action is wrong, they may have just as good reasons for their respective judgements; it is even possible that, were they fully informed about all the facts, equally imaginative, and so forth, they would still hold on to their respective (conflicting) judgements. They are each fully justified in their belief in conflicting judgements. I will comment on this form of moral relativism in passing. Finally, however, there is a kind of moral relativism we could call ontological, according to which, when two persons pass conflicting moral verdicts on a certain action, they may both be right. The explanation is that they make their judgements from the perspective of different, socially constructed, moral universes. So while it is true in the first person's moral universe that a certain action is right, it is true in the second person's moral universe that the very same action is wrong. I explain and defend this version of ontological moral relativism.     

Cognitive conflict and inhibition in primed dichotic listening

In previous behavioral studies, a prime syllable was presented just prior to a dichotic syllable pair, with instructions to ignore the prime and report one syllable from the dichotic pair. When the prime matched one of the syllables in the dichotic pair, response selection was biased towards selecting the unprimed target. The suggested mechanism was that the prime was inhibited to reduce conflict between task-irrelevant prime processing and task-relevant dichotic target processing, and a residual effect of the prime inhibition biased the resolution of the conflict between the two targets. The current experiment repeated the primed dichotic listening task in an event-related fMRI setting. The fMRI data showed that when the task-irrelevant prime matched the task-relevant targets, activations in posterior medial frontal cortex (pMFC) and in right inferior frontal gyrus (IFG) increased, which was considered to represent conflict and inhibition, respectively. Further, matching trials where the unprimed target was selected showed activation in right IFG, while matching trials where the primed target was selected showed activations in pMFC and left IFG, indicating the difference between inhibition-biased selection and unbiased selection.     

Relationship between heart rate variability and cognitive function during threat of shock

The aim of the present study was to investigate the relationship between resting heart rate variability (HRV) and cognitive functions during threat of shock. A Continuous Performance Task and a Working Memory Task were used to measure cognitive functions. Sixty-five male participants from the Royal Norwegian Navy participated. HRV was measured during baseline, test conditions and recovery. Participants were randomly assigned into non-threat and threat groups. Based on the median split of the high frequency (HF) spectral power, groups were divided into two additional groups. Overall, the high HRV participants showed superior performance on cognitive tasks independent of non-threat or threat conditions. During threat condition the low HRV group showed improved performance. Thus, individuals with high HRV were more stress tolerant and resilient in the face of environmental changes. The results from the study might have implications with regard to performance in operational settings, but also for other fields of psychological research such as individual differences, anxiety and coping.     

Perceptions of traffic risk in an industrialised and a developing country

This study aimed to investigate differences in traffic risk perception among a Norwegian and Ghanaian public. This was carried out while controlling for relevant background variables such as gender, age, and levels of educational achievement. In order to obtain the core aim of the study, a self-completion questionnaire was devised and distributed to a representative sample of the Norwegian population (n = 247) and to a stratified sample in Accra and Cape-Coast in Ghana (n = 299). The results showed that the Ghanaian sample perceived higher traffic risk than the Norwegian sample. Gender, age, and levels of educational achievement exerted minimal influences on risk perception. The results were discussed in context of industrialisation, cultural differences, and health beliefs.     

Effects of attentional-focus instructions on movement kinematics

BackgroundRecent research has shown that internal (body-related) attention-focus instructions disrupt motor learning and performance, whereas paying attention to the environmental effects of movements (external focus) leads to better performance than an internal focus [see, for reviews, Wulf, G. (2007). Attentional focus and motor learning: a review of 10 years of research. E-Journal Bewegung und Training, 1, 4–14.; Wulf, G., &; Prinz, W. (2001). Directing attention to movement effects enhances learning: a review. Psychonomic Bulletin &; Review, 8, 648–660.]. However, Beilock's studies [Beilock, S. L., Bertenthal, B. I., McCoy, A. M., &; Carr, T. H. (2004). Haste does not always make waste: expertise, direction of attention, and speed versus accuracy in performing sensorimotor skills. Psychonomic Bulletin &; Review, 11, 373–379.] suggest that an internal focus is detrimental in experts but not in novices. Because detrimental effects of consciously attending to movements have generally been measured by performance scores such as accuracy scores or reaction times, it remains unclear how internal and external attentional-focus instructions influence movement kinematics when learning a new skill. To fill this gap, the present study investigated attentional-focus effects on a biomechanical level.MethodsA video of an expert juggler demonstrating a two-ball juggling task was presented to juggling novices. Experimental groups were given either body-related (internal group) or ball-related (external group) verbal instructions or no attention-guiding instructions (control group). In the retention phase without attention-guiding instructions, the body-movement and ball-flight aspects of performance focused on in the verbal instruction were subjected to biomechanical analyses.Results and ConclusionsJuggling performance improved equally in all three groups. However, internally vs. externally instructed acquisition phases had differential effects on the kinematics of the upper body as well as ball trajectories when performing the juggling task. Remarkably, ball trajectories in the control group who received no specific attentional cueing were similar to those in the externally instructed group. This suggests that task-relevant information is picked up independently of instructions, and that external instructions provide redundant information. Internal instructions for object-related tasks, however, may confront novice learners with the need to process additional information. As a result, task difficulty might be unnecessarily enhanced in an observational learning setting.     

Signaling in large-scale neural networks

We examine the recent finding that neurons in spinal motor circuits enter a high conductance state during functional network activity. The underlying concomitant increase in random inhibitory and excitatory synaptic activity leads to stochastic signal processing. The possible advantages of this metabolically costly organization are analyzed by comparing with synaptically less intense networks driven by the intrinsic response properties of the network neurons.     

That’s Not Science! The Role of Moral Philosophy in the Science/Non-science Divide

The science/non-science distinction has become increasingly blurred. This paper investigates whether recent cases of fraud in science can shed light on the distinction. First, it investigates whether there is an absolute distinction between science and non-science with respect to fraud, and in particular with regards to manipulation and fabrication of data. Finding that it is very hard to make such a distinction leads to the second step: scrutinizing whether there is a normative distinction between science and non-science. This is done by investigating one of the recent internationally famous frauds in science, the Sudbø case. This case demonstrates that moral norms are not only needed to regulate science because of its special characteristics, such as its potential for harm, but moral norms give science its special characteristics. Hence, moral norms are crucial in differentiating science from non-science. Although this does not mean that ethics can save the life of science, it can play a significant role in its resuscitation.     

Computer-based automatic finger- and speech-tracking system

This article presents the first technology ever for online registration and interactive and automatic analysis of finger movements during tactile reading (Braille and tactile pictures). Interactive software has been developed for registration (with two cameras and a microphone), MPEG-2 video compression and storage on disk or DVD as well as an interactive analysis program to aid human analysis. An automatic finger-tracking system has been implemented which also semiautomatically tracks the reading aloud speech on the syllable level. This set of tools opens the way for large scale studies of blind people reading Braille or tactile images. It has been tested in a pilot project involving congenitally blind subjects reading texts and pictures.
