Martin's Axiom,Omitting Types,and Complete Representations in Algebraic Logic

We give a new characterization of the class of completely representable cylindric algebras of dimension 2 #lt; n w via special neat embeddings. We prove an independence result connecting cylindric algebra to Martin's axiom. Finally we apply our results to finite-variable first order logic showing that Henkin and Orey's omitting types theorem fails for L _n, the first order logic restricted to the first n variables when 2 #lt; n#lt;w. L _n has been recently (and quite extensively) studied as a many-dimensional modal logic.     

When the self represents the other: a new cognitive neuroscience view on psychological identification

There is converging evidence from developmental and cognitive psychology, as well as from neuroscience, to suggest that the self is both special and social, and that self-other interaction is the driving force behind self-development. We review experimental findings which demonstrate that human infants are motivated for social interactions and suggest that the development of an awareness of other minds is rooted in the implicit notion that others are like the self. We then marshall evidence from functional neuroimaging explorations of the neurophysiological substrate of shared representations between the self and others, using various ecological paradigms such as mentally representing one's own actions versus others' actions, watching the actions executed by others, imitating the others' actions versus being imitated by others. We suggest that within this shared neural network the inferior parietal cortex and the prefrontal cortex in the right hemisphere play a special role in the essential ability to distinguish the self from others, and in the way the self represents the other. Interestingly, the right hemisphere develops its functions earlier than the left.     

Development of phonological and orthographic processing in reading aloud,in silent reading,and in spelling: a four-year longitudinal study

The development of phonological and orthographic processing was studied from the middle of Grade 1 to the end of Grade 4 (age 6; 6-10 years) using the effects of regularity and of lexicality in reading aloud and in spelling tasks, and using the effect of pseudohomophony in a silent reading task. In all the tasks, signs of reliance on phonological processing were found even when indicators of reliance on orthographic processing appeared. Multiple regression analyses were conducted to determine which early skills predict later reading achievement. Pseudoword and irregular word scores were used as measures for phonological and orthographic skills, respectively. Only middle of Grade 1 phonological reading skills accounted for independent variance in end of Grade 4 orthographic skills. Conversely, from the middle to the end of Grade 1, and from the end of Grade 1 to the end of Grade 4, both orthographic and phonological skills accounted for independent variance in later orthographic skills. In the prediction of phonological skills, only the unique contribution of earlier phonological skills was significant. Thus, phonological and orthographic processing appear to be reciprocally related, rather than independent components of written word recognition. However, very early reliance on the phonological procedure seems to be the bootstrapping mechanism for reading acquisition.     

Orthographic learning at a glance: on the time course and developmental onset of self-teaching

Experiment 1 examined the time course of orthographic learning among Grade 3 children. A single encounter with a novel orthographic string was sufficient to produce reliable recall of orthographic detail. Moreover, newly acquired orthographic information was retained 1 month later. These data support the logistic learning functions featured in contemporary connectionist models of reading rather than a "threshold" model of orthographic learning. Experiments 2 and 3 examined self-teaching among novice readers. In contrast to the findings from less regular orthographies such as English and Dutch, beginning readers of a highly regular orthography (Hebrew) appear to be relatively insensitive to word-specific orthographic detail, reading in a nonlexical "surface" fashion. These results suggest fundamental differences between shallow and deep orthographies in the development of orthographic sensitivity.     

Hostile/Helpless maternal representations in pregnancy and later child removal: A pilot study

This article presents the results of a small pilot study examining links between Hostile/Helpless (HH) representations of caregiving in pregnancy and later child removal by child protective services. The sample was drawn from a replication study of the Minding the Baby^® attachment‐based home‐visiting intervention conducted in the United Kingdom, serving young first‐time mothers in under resourced communities. The HH classification system (Lyons‐Ruth et al.) was adapted for use with the Pregnancy Interview (PI) (Slade); 26 PIs were assessed (coders blinded) in a sample that included 13 mothers whose infants were removed from custody due to anticipated or documented maltreatment within 2 years of childbirth, and 13 mothers who did not have their infants removed. Mothers whose infants were removed from their custody had significantly higher HH scores than mothers of infants who were not removed from their care (F(1, 24) = 14.500, p < .001), and the relation between overall HH classification and infant removal status was also significant (χ²(1, N = 26) = 12.462, p < .001). Results suggest that prenatal maternal caregiving representations may predict postnatal relationship disruptions, and indicate the need for larger studies further testing this prenatal approach to maltreatment risk assessment in at‐risk populations.     

Visual and Affective Multimodal Models of Word Meaning in Language and Mind

One of the main limitations of natural language-based approaches to meaning is that they do not incorporate multimodal representations the way humans do. In this study, we evaluate how well different kinds of models account for people's representations of both concrete and abstract concepts. The models we compare include unimodal distributional linguistic models as well as multimodal models which combine linguistic with perceptual or affective information. There are two types of linguistic models: those based on text corpora and those derived from word association data. We present two new studies and a reanalysis of a series of previous studies. The studies demonstrate that both visual and affective multimodal models better capture behavior that reflects human representations than unimodal linguistic models. The size of the multimodal advantage depends on the nature of semantic representations involved, and it is especially pronounced for basic-level concepts that belong to the same superordinate category. Additional visual and affective features improve the accuracy of linguistic models based on text corpora more than those based on word associations; this suggests systematic qualitative differences between what information is encoded in natural language versus what information is reflected in word associations. Altogether, our work presents new evidence that multimodal information is important for capturing both abstract and concrete words and that fully representing word meaning requires more than purely linguistic information. Implications for both embodied and distributional views of semantic representation are discussed.     

The Formal Structure of Kind Representations

Kind representations, concepts like table, triangle, dog, and planet, underlie generic language. Here, we investigate the formal structure of kind representations—the structure that distinguishes kind representations from other types of representations. The present studies confirm that participants distinguish generic-supporting properties of individuals (e.g., this watch is made of steel) and accidental properties (e.g., this watch is on the nightstand). Furthermore, work dating back to Aristotle establishes that only some generic-supporting properties bear a principled connection to the kind, that is, are true of an individual by virtue of its being a member of a specific kind (e.g., telling time for a watch). The present studies tested the hypothesis that principled connections are part of the formal structure of kind representations. Specifically, they tested whether they structure a newly learned kind representation. Experiment 1 found that introducing a property of a newly encountered novel kind in any one of four linguistic frames that provide evidence that a property has a principled connection to a kind (e.g., “It has fur because it is a blick”) led participants to infer a different conceptual consequence of principled connections (i.e., “There is something wrong with this blick, which does not have fur”) for which they had no direct evidence. Two introduction frames that provided no evidence for principled connections (e.g., “Almost all blicks have fur”) did not generate the same consequence. Experiment 2 found that all of the targeted properties were generic licensing, irrespective of the introduction frame. That the distinction between properties that bear principled connections to their kinds, and merely generic-supporting properties structures novel kind representations, provides strong evidence that this distinction is part of the formal structure of kind representations.     

Externalizing behaviors and attachment disorganization in children of different‐sex separated parents: The protective role of joint physical custody

The aim of this study was to examine the relationship between externalizing behaviors and the quality of attachment representations in preschool children, and to determine if family type and custody arrangement had a moderating effect on this relationship. The participants were 33 girls and 31 boys (n = 64) aged between three and six years (M = 4.75; SD = 0.87 years) and their mothers. Among them, 36 came from “intact” families, 13 were living mainly with their mothers and 15 were in joint physical custody. Children’s attachment representations were assessed with the Attachment Story Completion Task (Bretherton, Ridgeway & Cassidy, 1990). Mothers reported on their child’s behavior problems using the Child Behavior Checklist (Achenbach & Rescorla, 2001) and on their alliance with the father using the Parenting Alliance Inventory (Abidin & Brunner, 1995). Although children’s externalizing behaviors were found to be associated with the disorganization of their attachment representations, this relationship was significantly weaker and was non‐significant for children in joint physical custody. Thus, the results of this pilot study suggest that joint custody may protect children of separated parents from the effects of attachment disorganization on externalizing behaviors.     

Minority Identity Strategies Bound by Prejudice: Restricted Perspectives of People Categorized as Gypsies in Hungary

In this study, we explored the identity strategies of Hungarian Gypsies with different socialization backgrounds, including the degree of majority and minority identifications, the contents of Gypsy identity as well as coping with threatening social situations. Sampling was based on external social categorization: majority members were asked for contacts to Gypsy acquaintances. Questionnaire data were used to assess socialization background, group identification and preferred coping strategies at different levels, while contents of Gypsy identity were explored in an associative network. Results suggest that subjects make an exclusive choice between national and ethnic identities. While all subjects prefer ethnic identity, subjects with different socialization backgrounds follow different identity strategies. In sum, large‐family subjects are emotionally attached to their ethnic group, avoid interaction with the majority and prefer the idea of a multicultural society. Small‐family subjects are emotionally detached from their ethnic group and vote for a homogeneous society. Results are interpreted in terms of integration‐related social policies. While these are aimed at the foundation of a recognized active minority, members of these new generations find the way of recognition in individual assimilation due to the threat of prejudice.
