ADAPT: a developmental, asemantic, and procedural model for transcoding from verbal to arabic numerals

This article presents a new model of transcoding numbers from verbal to arabic form. This model, called ADAPT, is developmental, asemantic, and procedural. The authors' main proposal is that the transcoding process shifts from an algorithmic strategy to the direct retrieval from memory of digital forms. Thus, the model is evolutive, adaptive, and particularly suited to account for learning and development. ADAPT, which has been implemented in a computer program, accounts for existing and new developmental data, for new data in adolescents with mild retardation, and for the neuropsychological cases described in the literature.     

Behavioral performances in participants with phonological dyslexia and different patterns on the N170 component

Adults with phonological dyslexia and controls performed a lexical decision task while ERPs were recorded in the occipitotemporal pathway. Based on N170 durations, two subgroups were formed: dysl1 showing longer N170 durations and dysl2 showing normal N170 durations. While the dysl1 subgroup had poorer accuracy for infrequent words and pseudo-words, the dysl2 group responded more slowly than controls to pseudo-words. N170 amplitudes were larger in the left hemisphere for controls irrespective of items. In the dysl1 subgroup, N170 amplitudes were larger in the left hemisphere than the right for words but not for pseudo-words, a sign of hemispheric compensation, while in the dysl2 subgroup signs of bilateralization were observed. Moreover, in the dysl1 subgroup, P100 amplitudes were smaller than controls. These results indicate different behavioral profiles of dyslexics with different patterns of P100 and N170 components. The ERP changes may be due to different behavioral strategies employed by each subgroup, logographic in dysl2 and phonological in dysl1.     

Development of Exploration and Investigation in the Norway Rat (Rattus norvegicus)

A cross-sectional study of the development of spontaneous exploratory behavior in the laboratory rat was conducted. Long-Evans hooded rat pups aged 11 to 28 days (n = 158, from 25 litters) were placed into a dimly illuminated arena for 10 min on 2 consecutive days. Analysis of videotaped records from the second session for each rat pup showed a relatively sudden emergence of locomotor exploration between 12 and 16 days of age. The behavioral topography of interactions with objects developed less uniformly, with some features (e.g., bout length) relatively unchanging and other features (e.g., number of bouts, number of different behaviors displayed) increasing with age. The data for locomotor exploration are consistent with an explanation that depends on maturation-driven emergence of species-typical behavior, but that explanation cannot account for the pattern of development for object investigation. These results provide further evidence that some important aspects of the character of exploratory behavior depend, at least partially, on experience, and that exploration is not in fact a single behavior system. In addition, they provide important baseline information for further studies of the structure and function of exploratory behavior.     

A test of the quasi-circumplex structure of human values

Schwartz’s value system (SVS) has been widely used in different disciplines (e.g., psychology, management, and marketing). Although the value structure seems to be validated when data are analyzed through multidimensional scaling, we show that the quasi-circumplex structure of human values is not supported when confirmatory analysis approaches (e.g., CIRCUM and constrained confirmatory factor analysis) are used. Based on two samples of French and Swiss respondents, confirmatory tests of SVS provide little support for its quasi-circumplex structure, mainly due to problems of construct and discriminant validity resulting from multicollinearity between value types.     

Gender congruence and body satisfaction in nonbinary transgender people: A case control study

Abstract

Background: Binary transgender people access gender affirming medical interventions to alleviate gender incongruence and increase body satisfaction. Despite the increase in nonbinary transgender people, this population are less likely to access transgender health services compared to binary transgender people. No research has yet understood why by exploring levels of gender congruence and body satisfaction in nonbinary transgender people.

Objective: The aim of this study was to compare levels of gender congruence and body satisfaction in nonbinary transgender people to controls [binary transgender people and cisgender (nontrans) people].

Method: In total, 526 people from a community sample in the UK took part in the study (97 nonbinary, 91 binary, and 338 cisgender identifying people). Participants were asked to complete an online survey about gender congruence and body satisfaction.

Results: There were differences in gender congruence and body satisfaction between nonbinary and binary transgender people. On sex-specific parts of the body (i.e., chest, genitalia, and secondary sex characteristics), nonbinary transgender people reported significantly higher levels of gender and body satisfaction compared to binary transgender people. However, there was no difference in congruence and satisfaction with social gender role between the two transgender groups (nonbinary and binary). Cisgender people reported significantly higher levels of gender congruence and body satisfaction compared to transgender people (nonbinary and binary).

Conclusions: There are differences in gender congruence and body satisfaction between nonbinary and binary transgender people. Nonbinary individuals may be less likely to access transgender health services due to experiencing less gender incongruence and more body satisfaction compared to binary transgender people. Transgender health services need to be more inclusive of nonbinary transgender people and their support and treatment needs, which may differ from those who identify within the binary gender system.

Introspective forgetting

We model the forgetting of propositional variables in a modal logical context where agents become ignorant and are aware of each others’ or their own resulting ignorance. The resulting logic is sound and complete. It can be compared to variable-forgetting as abstraction from information, wherein agents become unaware of certain variables: by employing elementary results for bisimulation, it follows that beliefs not involving the forgotten atom(s) remain true. The work for this publication was mainly carried out while Hans van Ditmarsch was associated to: Institut de Recherche en Informatique, Université Paul Sabatier, France.
