Stability in cognition across early childhood. A developmental cascade

Children confront the formidable task of assimilating information in the environment and accommodating their cognitive structures to that information. Developmental science is concerned equally with two distinctive features of these processes: children's group mean level of performance through time and the standing of individual children through time. Prevailing opinion since the inception of the mental-measurement movement has been that individual development is unstable-that individual children change unpredictably in their abilities. We report results of a large-scale controlled, multivariate, prospective, microgenetic, 4-year longitudinal study that reveals a statistically significant cascade of species-typical cognitive abilities from infancy to childhood. Infancy is a recognizable starting point of life; we find that to a small but significant degree, infancy also represents a setting point in the life of the individual.     

QUAL and the dynamics of evolution

The emergence of the first structures that are capable of “replication” is a mysterious problem of evolution. The majority of the scientists dealing with evolution agree on the point that this is the very property that differenciate animate and inanimate beings. The main purpose of the present paper is to prove that the phenomenon of replication cannot be forced into frames of the Bios, but is an inherent attribute of the material, and the biological replication is a more advanced and perfect manifestation of this attribute.

The cohesion and resistance, in a general sense, is the attribute of any material system, i.e. it is an attribute of coexistence that makes possible its life. This may be the property that was identified as Jacob Böhme's mystic concept “Qual”. The self‐preservation, the cohesion in a general sense is manifested against the different destructive effects by scattering the “attacked” system into successor systems. This process makes possible for the different successive systems to get among other, differing circumstances than they were before the destructive forces began to exercise their impact. These other circumstances however include the possibility of the emergence of other systems of interrelatedness, and the successive system may become different from the parent system. The multiplication and scattering, due to the impact of destruction, at the same time increase the system's surface of interaction, and this leads to an organization of higher level.     

Neutron and X-ray diffraction studies and cohesive interface model of the fatigue crack deformation behavior

The crack-tip deformation behavior during a single overload, fatigue test of ferritic stainless steel, and Ni-based HAYNES 230 superalloy is studied at different structural levels using (1) neutron-diffraction, from which both the elastic-lattice strain and volume-averaged total dislocation densities are obtained, (2) polychromatic X-ray microdiffraction to probe the geometrically necessary dislocations and boundaries distribution, and (3) an irreversible and hysteretic cohesive interface model which has been implemented into a finite element framework to simulate the stress/strain evolution near the fatigue crack tip. Neutron strain measurements and finite element simulations are in qualitative agreement on the macroscopic length scale. Large plastic deformation induced by the overload and the resulting compressive residual strains are observed in front of the crack tip after the overload, and are the principal reason for the fatigue-crack-growth retardation. Strong strain gradients surrounding the crack propagation result in the formation of a high density of geometrically necessary dislocations near the fractured surface and cause local lattice rotations on the submicron level.     

Similarity chains in the transformational paradigm

Rips’ (1989) results with the transformational paradigm have often been cited as supporting accounts of categorisation not based on similarity, such as involving necessary or sufficient features (or a belief in such features), which guarantee a categorisation outcome once their presence has been established. We discuss a similarity account of the transformational paradigm based on similarity chains, which predicts that when the transformation is more gradual the identity of the transformed object is less likely to change. Conversely, we suggest that an essentialist approach to categorisation predicts that essences are more likely to change in gradual transformations, across generations, as is the case with evolutionary change of species. In two experiments we examined the scope of the similarity versus the essentialist account in the transformational paradigm. With space aliens, the similarity account was superior to the essentialist one, but the converse was true with earth creatures. We suggest that an essentialist mode of categorisation is more likely than a similarity one for stimuli that are in better correspondence with our naïve understanding of the world.

Smoking reduces language lateralization: a dichotic listening study with control participants and schizophrenia patients

Schizophrenia has been associated with deficits in functional brain lateralization. According to some authors, the reduction of asymmetry could even promote this psychosis. At the same time, schizophrenia is accompanied by a high prevalence of nicotine dependency compared to any other population. This association is very interesting, because sex-dependent effects of smoking in auditory language asymmetries have been reported recently, and the verbal domain is also one major focus in cognitive deficit studies of schizophrenia. Thus, the altered laterality pattern in schizophrenia could, at least in part, result from secondary artefacts due to smoking rather than being a pure cause of the disease itself. To test this hypothesis, the present study examined auditory language lateralization in 67 schizophrenia patients and in 72 healthy controls in a phonemic and an emotional dichotic listening task. Our findings replicate previous research, in that smoking reduces language lateralization in men in phonemic dichotic listening. In addition, we show that smoking also reduces laterality in women in the emotional dichotic listening task. Thus, smoking alters phonemic and emotional language asymmetries differentially for men and women, with a stronger effect for men in the left hemisphere phonemic task, and a stronger effect for women in the right hemisphere emotional task. Together, these findings point towards an effect of smoking which is possibly independent of sex and hemisphere. Importantly, by testing equal numbers of smoking and non-smoking patients and controls, we found no schizophrenia-associated asymmetry effect. Possible neurobiological mechanisms with which smoking may alter auditory microcircuits and thereby diminish left-right differences are discussed.     

Entropy,semantic relatedness and proximity

Although word co-occurrences within a document have been demonstrated to be semantically useful, word interactions over a local range have been largely neglected by psychologists due to practical challenges. Shannon’s (Bell Systems Technical Journal, 27, 379–423, 623–665, 1948) conceptualization of information theory suggests that these interactions should be useful for understanding communication. Computational advances make an examination of local word–word interactions possible for a large text corpus. We used Brants and Franz’s (2006) dataset to generate conditional probabilities for 62,474 word pairs and entropy calculations for 9,917 words in Nelson, McEvoy, and Schreiber’s (Behavior Research Methods, Instruments, & Computers, 36, 402–407, 2004) free association norms. Semantic associativity correlated moderately with the probabilities and was stronger when the two words were not adjacent. The number of semantic associates for a word and the entropy of a word were also correlated. Finally, language entropy decreases from 11 bits for single words to 6 bits per word for four-word sequences. The probabilities and entropies discussed here are included in the supplemental materials for the article.     

Maternal responsiveness to young children at three ages: longitudinal analysis of a multidimensional, modular, and specific parenting construct

Responsiveness defines the prompt, contingent, and appropriate reactions parents display to their children in the context of everyday exchanges. Maternal responsiveness occupies a theoretically central position in developmental science and possesses meaningful predictive validity over diverse domains of children's development, yet basic psychometric features of maternal responsiveness are still poorly understood. In this prospective longitudinal study, the authors examined structure, individual variation, and continuity of multiple dimensions of responsiveness in 40 mothers to their infants' activities at 10, 14, and 21 months during natural home-based play interactions. Both age-general and age-specific patterns emerged in maternal responding. The study's developmental results support the multidimensionality, modularity, and specificity of this central parenting construct.
