Abstract
Research on orthographic consistency in English words has selectively identified different sub-syllabic units in isolation (grapheme, onset, vowel, coda, rime), yet there is no comprehensive assessment of how these measures affect word identification when taken together. To study which aspects of consistency are more psychologically relevant, we investigated their independent and composite effects on human reading behavior using large-scale databases. Study 1 found effects on adults' naming responses of both feedforward consistency (orthography to phonology) and feedback consistency (phonology to orthography). Study 2 found feedback but no feedforward consistency effects on visual and auditory lexical decision tasks, with the best predictor being a composite measure of consistency across grapheme, rime, OVC, and word-initial letter-phoneme. In Study 3, we explicitly modeled the reading process with forward and backward flow in a bidirectionally connected neural network. The model captured latent dimensions of quasi-regular mapping that explain additional variance in human reading and spelling behavior, compared to the established measures. Together, the results suggest interactive activation between phonological and orthographic word representations. They also validate the role of computational analyses of language to better understand how print maps to sound, and what properties of natural language affect reading complexity.

Abstract
Bilinguals are widely reported to have certain kinds of cognitive advantages, including language learning advantages. One possible pathway is a language-specific transfer effect, whereby sensitivity to structural regularities in known languages can be brought to to-be-acquired languages that share particular features. Here we tested for transfer of a specific linguistic property, sensitivity to retroflexion as contrastive phonemic feature. We designed a task for bilinguals with homogeneous language exposure (i.e., bilingual in the same languages) and heterogeneous feature representation (i.e., differing levels of proficiency). Hindi and Mandarin Chinese both have retroflexion in phoneme contrasts (Hindi: stop consonants, Mandarin: sibilants). In a preregistered study, we conducted a statistical learning task for the Hindi dental-retroflex stop contrast with a group of early parallel English-Mandarin bilinguals, who varied in their Mandarin understanding levels. We based the target sample size on power analysis of a pilot study with a Bayesian stop-rule after minimum threshold. Contrary to the pilot study (N = 15), the main study (N = 50) did not find evidence for a learning effect, nor language-experience variance within the group. This finding suggests that statistical effects for the feature in question may be more fragile than commonly assumed, and may be evident in only a small subsample of the general population (as in our pilot). These stimuli have previously shown learning effects in children, so an additional possibility is that neural commitment to adults' languages prevents learning of the fine-grained stimulus contrast in question for this adult population.

Abstract
Prediction is one characteristic of the human mind. But what does it mean to say the mind is a "prediction machine" and inherently forward looking as is frequently claimed? In natural languages, many contexts are not easily predictable in a forward fashion. In English, for example, many frequent verbs do not carry unique meaning on their own but instead, rely on another word or words that follow them to become meaningful. Upon reading take a the processor often cannot easily predict walk as the next word. But the system can "look back" and integrate walk more easily when it follows take a (e.g., as opposed to *make|get|have a walk). In the present paper, we provide further evidence for the importance of both forward and backward-looking in language processing. In two self-paced reading tasks and an eye-tracking reading task, we found evidence that adult English native speakers' sensitivity to word forward and backward conditional probability significantly predicted reading times over and above psycholinguistic predictors of reading latencies. We conclude that both forward and backward-looking (prediction and integration) appear to be important characteristics of language processing. Our results thus suggest that it makes just as much sense to call the mind an "integration machine" which is inherently backward 'looking.'

Abstract
An important debate on the architecture of the language faculty has been the extent to which it relies on a compositional system that constructs larger units from morphemes to words to phrases to utterances on the fly and in real time using grammatical rules; or a system that chunks large preassembled, stored units of language from memory; or some combination of both approaches. Good empirical evidence exists for both 'computed' and 'large stored' forms in language, but little is known about what shapes multi-word storage/ access or compositional processing. Here we explored whether predictive and retrodictive processes are a likely determinant of multi-word storage/ processing. Our results suggest that forward and backward predictability are independently informative in determining the lexical cohesiveness of multi-word phrases. In addition, our results call for a reevaluation of the role of retrodiction in contemporary language processing accounts (cf. Ferreira and Chantavarin, 2018).

Abstract
Technology plays an increasingly important role in educational practice, including interventions for struggling learners (Torgesen et al., 2010; de Souza et al., 2018). This study focuses on the efficacy of tablet-based applications (see Word Reading, Grapholearn, and an experimental word-level program) for the purpose of supplementing early English literacy intervention with primary grades 1 and 2 children. The children were identified for learning support programs within Singaporean schools, which follow a bilingual policy, meaning children were learning reading in English plus an additional language. One hundred forty-seven children across seven schools participated (Mean age = 6.66). Within learning support classrooms, triplets of students matched on basic reading skills were randomly assigned to one of three groups: (1) phoneme-level, (2) rime-level, or (3) word-level focused interventions. All groups performed reading skills activities on iPads, across two phases over a 14-week period. Assessments for word reading accuracy and fluency, pseudoword decoding accuracy and fluency, and spelling were administered at four time points, pre- and post-intervention. Additional baseline measures were taken to assess individual differences in phonological awareness, orthographic awareness, general cognitive ability, statistical learning, and bilingual vocabulary knowledge. Mixed model analysis was conducted on the pre- to post-test measures across the two phases of the intervention (focused on accuracy then fluency). All groups made gains across the different literacy measures, while the phoneme-level intervention showed an advantage over the rime-level intervention, but not the word-level intervention, for decoding. There were also moderating effects of individual differences on outcomes. The general pattern of results showed an advantage of the word-level intervention for those with poorer phonological awareness for reading fluency; and a phoneme-level intervention advantage for those with poorer statistical learning ability. Children's bilingual group (English plus Mandarin, English plus Malay, or English plus Tamil) also showed differential effects of the type of intervention (e.g., phoneme- or word-level) on different outcome measures. These results, along with data collected from the tablets during the intervention, suggest the need to examine the interplay between different types of technology-based interventions and individual differences in learning profiles.

Abstract
Language development requires both basic cognitive mechanisms for learning language and a rich social context from which learning takes off. Disruptions in learning mechanisms, processing abilities, and/or social interactions increase the risks associated with social exclusion or developmental delays. Given the complexity of language processes, a multilevel approach is proposed where both cognitive mechanisms, genetic and environmental factors need to be probed together with their possible interactions. Here we review and discuss such interplay between environment and genetic predispositions in understanding language disorders, with a particular focus on a possible endophenotype, the ability for statistical sequential learning.

Abstract
Human language appears to be unique among natural communication systems, and such uniqueness impinges on both nature and nurture. Human babies are endowed with cognitive abilities that predispose them to learn language, and this process cannot operate in an impoverished environment. To be effectively complete the acquisition of human language in human children requires highly socialised forms of learning, scaffolded over years of prolonged and intense caretaker-child interactions. How genes and environment operate in shaping language is unknown. These two components have traditionally been considered as independent, and often pitted against each other in terms of the nature versus nurture debate. This perspective article considers how innate abilities and experience might instead work together. In particular, it envisages potential scenarios for research, in which early caregiver verbal and non-verbal attachment practices may mediate or moderate the expression of human genetic systems for language.

Abstract
Language acquisition may be one of the most difficult tasks that children face during development. They have to segment words from fluent speech, figure out the meanings of these words, and discover the syntactic constraints for joining them together into meaningful sentences. Over the past couple of decades, computational modeling has emerged as a new paradigm for gaining insights into the mechanisms by which children may accomplish these feats. Unfortunately, many of these models assume a computational complexity and linguistic knowledge likely to be beyond the abilities of developing young children. This article shows that, using simple statistical procedures, significant correlations exist between the beginnings and endings of a word and its lexical category in English, Dutch, French, and Japanese. Therefore, phonetic information can contribute to individuating higher level structural properties of these languages. This article also presents a simple 2-layer connectionist model that, once trained with an initial small sample of words labeled for lexical category, can infer the lexical category of a large proportion of novel words using only word-edge phonological information, namely the first and last phoneme of a word. The results suggest that simple procedures combined with phonetic information perceptually available to children provide solid scaffolding for emerging lexical categories in language development.

Abstract
This article presents the results of a broader clinical research into the effectiveness of integrated treatments in teenage eating disorders, carried out at the Complex Operative Unit of Psychotherapy (Unità Operativa Complessa or U.O.C.) of the Department of Psychiatric Sciences and Psychological Medicine in collaboration with the Department of Neuropsychiatric Science for Child Development (Dipartimento di Scienze Neuropsichiatriche dell'Età Evolutiva), both at the "La Sapienza" University of Rome. The hypothesis of this research project is that in diagnosticable situations such as anorexia or bulimia, an integrated and multidisciplinary treatment, which combines medical-nutritional interventions and family psychotherapy, allows better results than a single kind of treatment, which is the usual medical- nutritional intervention supported by psychiatric counselling. Twenty-eight cases (16 of bulimia and 12 of anorexia) were selected and then subdivided, with a randomized distribution, into two (experimental and control) homogeneous groups of 14 patients. The grouping variables were the diagnosis, the disorder's seriousness and duration, BMI, gender, age, family composition and social status. The variables which have been examined in this article are the clinical parameters, which were valuated in accordance with the DSM IV-TR criteria, and relational parameters which were explored through the use of the W.F.T. Test (Wiltwyck Family Tasks). These parameters were tested at beginning as well as at the end of the therapies, in both the experimental group and the control group. Statistical analysis has shown that the experimental group, which was followed with the integrated treatment, experienced a significant improvement of the parameters as related to dysfunctional family interaction modalities, and that this improvement was correlated to the positive evolution of the clinical parameters. This improvement was not present or not of the same degree in the control group. The results, moreover, demonstrate the effectiveness of an integrated systemic treatment based on a complex approach compared to a reductionist approach.

Abstract
We used event-related potentials (ERPs) to investigate the time course and distribution of brain activity while adults performed (a) a sequential learning task involving complex structured sequences, and (b) a language processing task. The same positive ERP deflection, the P600 effect, typically linked to difficult or ungrammatical syntactic processing, was found for structural incongruencies in both sequential learning as well as natural language, and with similar topographical distributions. Additionally, a left anterior negativity (LAN) was observed for language but not for sequential learning. These results are interpreted as an indication that the P600 provides an index of violations and the cost of integration of expectations for upcoming material when processing complex sequential structure. We conclude that the same neural mechanisms may be recruited for both syntactic processing of linguistic stimuli and sequential learning of structured sequence patterns more generally.

Abstract
This paper reports progress in developing a computer model of language acquisition in the form of (1) a generative grammar that is (2) algorithmically learnable from realistic corpus data, (3) viable in its large-scale quantitative performance and (4) psychologically real. First, we describe new algorithmic methods for unsupervised learning of generative grammars from raw CHILDES data and give an account of the generative performance of the acquired grammars. Next, we summarize findings from recent longitudinal and experimental work that suggests how certain statistically prominent structural properties of child-directed speech may facilitate language acquisition. We then present a series of new analyses of CHILDES data indicating that the desired properties are indeed present in realistic child-directed speech corpora. Finally, we suggest how our computational results, behavioral findings, and corpus-based insights can be integrated into a next-generation model aimed at meeting the four requirements of our modeling framework.

Abstract
When learning language, young children are faced with many seemingly formidable challenges, including discovering words embedded in a continuous stream of sounds and determining what role these words play in syntactic constructions. We suggest that knowledge of phoneme distributions may play a crucial part in helping children segment words and determine their lexical category, and we propose an integrated model of how children might go from unsegmented speech to lexical categories. We corroborated this theoretical model using a two-stage computational analysis of a large corpus of English child-directed speech. First, we used transition probabilities between phonemes to find words in unsegmented speech. Second, we used distributional information about word edges--the beginning and ending phonemes of words--to predict whether the segmented words from the first stage were nouns, verbs, or something else. The results indicate that discovering lexical units and their associated syntactic category in child-directed speech is possible by attending to the statistics of single phoneme transitions and word-initial and final phonemes. Thus, we suggest that a core computational principle in language acquisition is that the same source of information is used to learn about different aspects of linguistic structure.

Abstract
Variation set structure--partial overlap of successive utterances in child-directed speech--has been shown to correlate with progress in children's acquisition of syntax. We demonstrate the benefits of variation set structure directly: in miniature artificial languages, arranging a certain proportion of utterances in a training corpus in variation sets facilitated word and phrase constituent learning in adults. Our findings have implications for understanding the mechanisms of L1 acquisition by children, and for the development of more efficient algorithms for automatic language acquisition, as well as better methods for L2 instruction.

Abstract
BACKGROUND The authors try to define the framework of this approach, what should be acquired by "well-informed" dermatologists and what is required to be a pyschodermatologist. OBJECTIVE To better define the necessary knowledge to practice psychodermatology. RESULTS 1) The first level is dermatology psychology: there is a psychotherapeutical implicit effect of the dermatological consultation with a goal that is not psychological change. This effect can be improved by acquiring better communication skills and information. The second level needs a possibility to change the emotional individual process and the relational context in a continuum between counselling and psychotherapy. To practice this level a complete psychotherapeutic education with some specificity is needed. This can be reached by a dermatologist also being a psychotherapist or by a team consisting of both dermatologist-psychotherapist. 2) The psychodermatological patient is characterized by alexithymia. He/she needs to be understood through the body language he/she presents. This kind of patient is coming from families where the theme of loss seems to dominate the histories and be associated with deep emotional experiences of separation anxiety. These characteristics must be known together with the different psychodermatological disorders and the mind-body interaction to handle these patients. 3) Taking all of this complexity into account, the psychodermatologist or the psychodermatological team should be able to integrate the different points and adapt attitudes to the patient's difficulty during the whole therapeutic process. 4) The evaluation of the problem should be done using psychological tools here described. CONCLUSION The European Academy of Dermatology and Venereology (EADV) together with the European Society for Dermatology and Psychiatry (ESDaP) are able to provide the specific education for dermatologist and psychotherapist. In the future, they could be responsible for the recognition of these special abilities and treatments on a governmental and European political level.

Abstract
This research project tries to test a therapeutic strategy that could improve the prognosis of anorexic and bulimic syndrome, by reducing their tendency to chronicity. The hypothesis is that, whenever we deal with complex, multifactoral syndromes, such as anorexia and bulimia, a therapy based upon the association of different kinds of treatments (medical-biological-nutritional treatments plus family therapy) helps to obtain better results than one type of treatment only (medical-biological-nutritional alone). The selection of the samples (experimental and control samples), the materials and methods of the research project, and the follow-up series are described.

Abstract
We present a therapeutic intervention model for use with psychosomatic families. This method, the result of our extensive research on various psychosomatic disorders, uses family sculptures of the "present" and "future": each family member is requested to represent the family as it now "is," and how it "will be" in the future. We discuss the theoretical reasons for our choice of this method: (a) the opportunity to use a therapeutic language that is similar to the nonverbal language of the psychosomatic symptom, and (b) the usefulness of reinserting temporal dimensions into family systems that seem to have lost their evolutionary potential and to be in a sort of "time lock." Two clinical cases are discussed (a child with chronic asthma and an anorexic adolescent); the use of sculptures in both cases revealed the underlying problems and made positive therapeutic interventions possible. Finally, we point out how the use of sculpture as a therapeutic technique enables therapists to deal with multiple systemic levels.

Abstract
A 50-year-old white woman with an 8-month history of Parkinson's syndrome which did not respond to levodopa therapy was found on pathological examination to have the topographical lesions of striato-nigral degeneration. In addition to those characteristic lesions, an associated degeneration of the optic pathways, from the level of the optic nerve to the geniculo-collicular fibers, of the corticospinal tract and of the olivo-dentate axis, were found. While offering further evidence for the concept of "multiple system degeneration", no pathogenetic relationship either to previous cases of striato-nigral degeneration or to other multiple system degenerations is implied.

Abstract
A case of Seitelberger's infantile neuroaxonal dystrophy (a rare familial neurologic disease of childhood) is described. The clinical picture is characterized by a progressive deterioration of psychomotor functions leading to flaccid paraplegia with hypotonia of axial muscles, complete involution of language, and total loss of communication with the external world; death due to recurrent unassociated disease occurred at the age of 4 years. Histology showed numerous axonal spheroids mainly in the gray matter of the C.N.S. and plurisystemic degenerations of the motor and sensory systems, of the cerebellum, of the basal ganglia, and of specific sensory system such as the optic and (reported here for the first time) of the olfactory and acoustic systems. In particular, the main histopathological findings included: 1) a characteristic distribution of axonal swellings prevailing in the posterior horn of the spinal cord and in the dorsolateral portions of the medulla oblongata, mainly at the level of the sensory nuclei; 2) demyelinization of the pyramidal tracts and of the ascendings pathways of the sensory system with fibrillar gliosis and myelin breakdown products in some areas (internal capsule, pes pedunculi, VPL thalamic nuclei); 3) severe cerebellar atrophy with almost complete loss of granule and Purkinje cells and marked fibrillary gliosis; 4) presence of enormous amount of sudanophilic lipids in the striatum and pallidum; 5) optic, acoustic and olfactory system degeneration with demyelinization and gliosis at all levels examined and, in particular, sudanophilic lipid deposition in the optic radiations, trigone, and olfactory striae. The discussion emphasized the dying-back type of evolution of the degenerative process insofar as a) the spheroids represent a peculiar alteration of presynaptic endings (as demonstrated by electron microscopy) prevailing at the first sensory neuron, and b) in all systems involved, the degeneration is most marked at distal levels. The striato-pallidal lipophanerosis suggests that the sudanophilic lipids are, here as in other systems, parenchymal degeneration products. On the other hand, there are still many unresolved problems in this rare and complex disease, such as a) the predilection of the lesions for the sensory systems which in our case involved all three special senses; b) the extreme cerebellar atrophy; and c) the etiopathogenetic substrate of the process. All biochemical and histochemical studies have not yielded any results up to the present.

Abstract
A case of meningeal carcinomatosis associated with cerebral metastases from an adrenal neuroblastoma is described. The clinical picture was ushered-in by bilateral sciatic pain in a 50 years old female and was followed by rapidly progressive sensory-motor deficits of the arms and legs, leading to flaccid quadriplegia associated with paralysis of cranial nerves and episodes of mental confusion. Death occurred 4 months alter, in cardiac failure. At autopsy, a bilateral tumor of the adrenal glands was found. No metastases were detected anywhere except in the central nervous system. Histology identified the tumor as a neuroblastoma; meningeal carcinomatosis, radicular infiltration by tumor cells and parenchimal metastases were found in the central nervous system. Neuroblastoma is typically a tumor of childhood, only 13% of them being found in adult's according to Russell and Rubinstein. Meningeal metastases from adrenal neuroblastoma have not hitherto been reported in the literature. In our opinion, the most likely mode of spread of tumor cells to the central nervous system was hematogenous because of the presence of small multiple intraparenchimal metastases; however, possible spread through the perineural lymphatics, as proposed by others, cannot be excluded, due to the prominent localization of tumor cells at spinal roots level. The main differential diagnostic problems (paraneoplastic neuropathy (Wyburn-Mason) and infectious subacute or chronic meningitis) are discussed. The authors stress the emportance of complete cerebro-spinal fluid examination including a careful search for tumor cells.

Abstract
A case of progressive myoclonic epilepsy (P.M.E.) is described. The clinical picture consisted of epileptic seizures, myoclonus and slight mental deterioration associated with a severe progressive cerebellar syndrome. The disease had a course of almost 20 years. Histological studies of the C.N.S. showed severe loss of Purkinje cells, sligth regressive changes in both dentate and olivary nuclei, nerve cells atrophy of anterior horn motoneurons, degeneration of Goll's and Burdach's spino-olivary and anterior spino-cerebellar tracts. Features of cellular lipidosis and/or neuronal amiloid inclusions were not seen. The case was therefore classified in the group of degenerative P.M.E. Its peculiar pathologic aspects consisted of slight but diffuse brain stem regressive changes associated with systemic degeneration involving the spino-cerebellar pathways. The clinical features of our patient emphasize the problem of differential diagnosis between. P.M.E. and D.C.M. thought of by French authors to be an autonomous entity both clinically )severe cerebellar syndrome, intentional myoclonus, absence or late appearance of epilepsy, slight or absent mental deterioration) and anatomically (primary atrophy of the dentate system). However there are many cases, similar to the one reported, which have a clinical course suggesting a diagnosis of D.C.M., but which differ neuropathologically from Hunt's syndrome because of the absence of primary atrophy of the dentate system. These borderline cases give supporting evidence to the concept of continuity between classical P.M.E. and D.C.M., as well as to the authors' opinion that 1unt's syndrome must be classified as a varient of degenerative P.M.E.
