Newborns modulate their crawling in response to their native language but not another language

Human newborns can propel themselves to their mother's breast when positioned skin to skin on her abdomen just after birth. For decades, researchers have considered this primitive crawling behavior a spinal reflex, immune to supra spinal control. However, recent research suggests that neonatal crawling is already responsive to visual and olfactory stimuli processed at a supra spinal level. Here we report that a few hours post birth, French newborns can also modulate their crawling in response to their native language – a source of information that is processed supra-spinally. The crawling patterns of 23 French-born newborns were recorded on video and via an infrared motion capture system during two randomly ordered 2-min trials. The newborns were secured on a mini skateboard to facilitate arm and leg movements during their crawling propulsion. They heard a repetitive sequence of the same sentences either in French, their native language, or in English, a rhythmically different and hence discriminable unfamiliar language, on each trial. In French, compared to English, crawling was enhanced, with significantly more arm and leg steps and significantly more and larger trunk rotations in the cephalo-caudal axis. Moreover, newborns rotated their heads and trunk toward the appropriate loud speaker when hearing French but not English. These preliminary findings suggest that newborn crawling is not a simple stereotyped reflex under spinal control, but a complex pattern that can be modulated in response to higher-order, supra-spinally processed stimuli. The findings open fascinating questions about the range of stimuli to which newborn crawling is responsive.

Teleonics of health and healthcare: Focus on health promotion

Teleonics is an approach to the study of living systems. The latter can be regarded as synergistic collections of processes through which the systems interact with their internal and external environments. Teleonics can serve as a framework for positioning issues of health into the wider context of the fabric of life. There are essentially three webs of processes that are of relevance for a discussion of healthcare, viz, the normal web of the living fabric (Biomatrix), the “web of disease” (Pathomatrix) and the web of Healthcare. The latter interacts with the first two through the processes of Health Promotion, Disease Prevention and Disease Management. The end result of these interactions is an entirely new web of great complexity that incorporates the processes of all three webs intertwined with each other. This complexity presents a considerable challenge to all those involved in healthcare and can only be untangled with the aid of a process‐based methodology, such as teleonics.     

Building Blocks Toward Contemporary Trauma Theory: Ferenczi 's Paradigm Shift

In laying down the building blocks of contemporary trauma theory, Ferenczi asserted that trauma is founded on real events and that it occurs in the interpersonal and intersubjective dynamics of object relations. He stressed the significance of the presence or lack of a trusted person in the post-traumatic situation. After the trauma, the loneliness and later the isolation of the victim represent a serious pathogenic source. In the traumatic situation, the victim and the persecutor/aggressor operate differing ego defense mechanisms. Ferenczi was the first to describe the ego defense mechanism of identification with the aggressor. Ferenczi pointed out the characteristic features of the role of analyst/therapist with which (s)he may assist the patient in working through the trauma, among them being the development of a therapeutic atmosphere based on trust, so that the traumatic experiences can be relived, without which effective therapeutic change cannot be achieved. For the analyst, countertransference, as part of authentic communication, is incorporated into the therapeutic process. These are the key building blocks that are laid down by Ferenczi in his writings and appear in later works on trauma theory.     

Scientific representation: against similarity and isomorphism

I argue against theories that attempt to reduce scientific representation to similarity or isomorphism. These reductive theories aim to radically naturalize the notion of representation, since they treat scientist's purposes and intentions as non-essential to representation. I distinguish between the means and the constituents of representation, and I argue that similarity and isomorphism are common but not universal means of representation. I then present four other arguments to show that similarity and isomorphism are not the constituents of scientific representation. I finish by looking at the prospects for weakened versions of these theories, and I argue that only those that abandon the aim to radically naturalize scientific representation are likely to be successful.     

Theorema: Towards computer-aided mathematical theory exploration

Theorema is a project that aims at supporting the entire process of mathematical theory exploration within one coherent logic and software system. This survey paper illustrates the style of Theorema-supported mathematical theory exploration by a case study (the automated synthesis of an algorithm for the construction of Gröbner Bases) and gives an overview on some reasoners and organizational tools for theory exploration developed in the Theorema project.     

The Jónsson-Kiefer Property

The least element 0 of a finite meet semi-distributive lattice is a meet of meet-prime elements. We investigate conditions under which the least element of an algebraic, meet semi-distributive lattice is a (complete) meet of meet-prime elements. For example, this is true if the lattice has only countably many compact elements, or if |L| < 2^ℵ0, or if L is in the variety generated by a finite meet semi-distributive lattice. We give an example of an algebraic, meet semi-distributive lattice that has no meet-prime element or join-prime element. This lattice L has |L| = |LC| = 2^ℵ0 where L_c is the set of compact elements of L.

Is action naming better preserved (than object naming) in Alzheimer's disease and why should we ask?

The present study compared object and action naming in patients with Alzheimer's dementia. We tested the hypothesis put forward in (some) previous studies that in Alzheimer's dementia the production of verbs, that is required in action naming, is better preserved than the production of nouns, that is required in object naming. The possible reason for the dissociation is that verbs are supported predominantly by frontal brain structures that may remain relatively better preserved in early Alzheimer's disease. Objects, on the other hand, are supported by temporal lobe structures that are affected early in the disease. An alternative hypothesis, which is supported by other studies, is that action naming is more impaired than object naming due to verbs being semantically more complex than nouns. In order to test these contrasting hypotheses, the present study used more stringent methodology than previous studies. We used a larger set of stimuli with carefully matched object and action items and we collected not only accuracy data but also naming latencies, a measure that is sensitive to even mild lexical retrieval problems. We compared the performance of 19 patients with mild to moderate Alzheimer's disease with that of 19 healthy age matched participants. We found that both the patients and the comparison group responded faster and made fewer errors on the object pictures than the action pictures. A qualitative analysis of the naming errors indicated that object and action naming pose different demands for the language system. The results overall suggest that the patients' performance is an exaggeration of the pattern present in the comparison participants.     

Interpolation and Amalgamation; Pushing the Limits. Part I

Continuing work initiated by Jónsson, Daigneault, Pigozzi and others; Maksimova proved that a normal modal logic (with a single unary modality) has the Craig interpolation property iff the corresponding class of algebras has the superamalgamation property (cf. [Mak 91], [Mak 79]). The aim of this paper is to extend the latter result to a large class of logics. We will prove that the characterization can be extended to all algebraizable logics containing Boolean fragment and having a certain kind of local deduction property. We also extend this characterization of the interpolation property to arbitrary logics under the condition that their algebraic counterparts are discriminator varieties. We also extend Maksimova's result to normal multi-modal logics with arbitrarily many, not necessarily unary modalities, and to not necessarily normal multi-modal logics with modalities of ranks smaller than 2, too.The problem of extending the above characterization result to no n-normal non-unary modal logics remains open.Related issues of universal algebra and of algebraic logic are discussed, too. In particular we investigate the possibility of extending the characterization of interpolability to arbitrary algebraizable logics.     

Personality profile for adolescents at risk for internalizing and externalizing problems

To estimate the personality profile for adolescents at psychopathological risk, a community sample of 762 adolescents, ages 12 to 16 years (M = 13.8, SD = 1.3), 53% boys and 47% girls, from the city of Barcelona, Spain, were tested with the Youth Self-Report and the High School Personality Questionnaire. Among this group, 140 adolescents were identified as showing symptoms of psychopathological risk for internalizing or externalizing syndromes as defined by Achenbach's theory. Analysis indicated that adolescents who scored high for internalizing and externalizing symptoms showed differing personality profiles, which also differed by sex. Boys scoring high on internalizing tended to adopt an inhibited, shy, and apprehensive behavior, while girls showed a tendency to display a more distant and cold affect and changeable emotionality. The personality pattern of boys and girls who scored high on externalizing symptoms showed both similar and different aspects. Both sexes displayed characteristics such as dominance, poor rule conformity, and low self-discipline. However, girls who scored high on externalizing symptoms also tended to show impulsiveness, social boldness, and low sensitivity.
