    Summary: Research conducted at the center Can Rubió of Esparraguera (NCB). OBJECTIVE assess the changes that produces an Institutional Care Program in organizing personality, in the relational functioning, coping problems and cognitive resources, and the possible relationship of these changes to certain circumstances of the subjects (in adolescents situation reamparo and with serious mental disorders). PROCEDURE are practiced three evaluations: outset, short-term (8 months) and the medium term 15 (months). Test scores at the outset compared with the rates of the respective tests (yardstick for adolescents Italians in the case of Rorschach). Test scores in the short and medium term are compared with those obtained from the outset, calculating the statistical significance of the different (T Wilcoxon) and the clinical significance based on the standard deviation (Cohen). We calculated trends (linear regression, least squares) to a selection of 17 indexes and the relationship (Spearman) with some of these trends circumstances of the subject. INSTRUMENTS Rorschach test, YSR, CRI and the subtests Vocabulary, Similarities and cubes of WISC-R. SUBJECT 31 at the beginning, 25 and 19 in the short and medium term, respectively (both sexes), with various types of mental pathology. RESULTS At the outset, many of emotional problems, behavior, dominance of avoidance strategies, the tendency to dissociation and / or performance failures in the internal and external perception, scarce resources ideacionales and emotional disorders numerous course and contents of thought, lack of interest in others, passivity and dependence on the environment and difficulties in perceiving the convencionalidad and norms of the group. In the short term, little change seen. In the medium term, improve the control and stress tolerance, self-perception, social identification, internalization, externalization and approach to conflict, diminish disruption of thought. It increases the tendency to passivity ideational, the unit's environment and avoidance as a coping strategy. The trend of improvement has a significant negative relationship with the number of psychiatric revenues and its duration. The trend towards improvement presents a significant negative correlation with the number of psychiatric revenues and its duration. The trend towards stagnation psychic presents a significant negative relationship with the family support. DISCUSSION The discrepción the results may be due to the presence of many factors related abandonismo, lack of genetic and family situation subjects and the absence of suffering psíquico-razones to change, introspection and confidence in others. CONCLUSIONS The introduction of a multi-modal model is feasible and provides good information for the analysis of the clinical development individually, to exchange with other professionals, as an indicator of the quality of service and generates a standardized database that allows research. This program is not intended for individuals who have made a lot of i / o lengthy psychiatric income. Age, psychopathology, family status, comorbidity and future prospects, make up some organizations pathologically crystallized personality and very difficult to change. Increased passivity ideational, the dependence of environment and the avoidance as a coping strategy required to identify which elements of the program itself, of the everyday and the rules of the center could contribute to an increase in these factors to make changes relevant in each of the three areas.

    Summary: Depression is one of the major mental health problems of today's society. In recent years there has been a growing interest in the assessment of depression infanto - juvenil. Depression in children and adolescents is an insidious disorder, in many occasions little recognized confused with other disorders, or understood as a normal variation of mood. The reasons for this are many and include, among others, the type of symptoms and often covert nature of the symptoms vision of the end of childhood and the beginning of adolescence as a time of change and emotional disorders, poor relationship and insufficient communication between some teenagers and parents or adult reference, as teachers, and lack of self-referral to professionals by adolescents. If we want the psychological assessment provides a portrait as close as possible to the functioning of the child or adolescent, we must avoid, at the outset, to grant a diagnostic label, seeking to evaluate different areas of operation and to collect information from various informants. It is also necessary to use various instruments including, if possible, categorical and dimensional approaches. Besides these instruments must be tailored to the population and the cultural context in which they apply and have appropriate standards for the age and sex of the evaluated. The aim of the thesis was to study the usefulness of an evaluation of depressive symptoms in children and adolescents, and people adapt to various Catalan self-report measures and heteroinforme assessing symptomatology psicopatológica in general, and depressive symptoms in particular. We have assessed two points of participants aged between 10 and 16 years: a community group (1706 participants) and a clinical (285 participants). Starting with the community group has selected a control group, with 46 participants, and one of risk, with 102 participants, and from clinical group, a sub-clinical, with 40 participants. The instruments were administered the Reynols Adolescent Depressión Scale (SADR), the Reynolds Child Depressión Scale (RCDS) and the Children's Depression Inventory (CDI) in the community group and clinical. In the control groups, and clinical risk have been administered, in addition, the Youth Self Report (YSR), the Child Behavior Checklist (CBCL), the Teacher Report Form (TRF), Deverex Scales of Mental disroders (DSMD) and diagnostic interview. Have been translated, Catalan and Spanish and adapted for this study the SADR, RCDS, IDC and DSMD. The process of translation has been done through a direct translation of the questionnaire from English to Spanish and from Spanish to Catalan by two translators and experts with knowledge of psychological assessment and psicopatológica and back translation of the Catalan and Spanish to English, translators by other experts.

    Summary: The present study was developed with the objective of exploring the relationship of school violence with variables such as ethnicity, gender (female profile, male and men and women), and abuse in the pupil-teacher interaction, variables that have been poorly explored in the study of school violence. The study involved 757 students at 1Â º to 4Â fifth of the SCS, public schools in Madrid. The results of the investigation that resulted in the identification: A - The most common situations of aggression are peer exclusion, rejection and verbal abuse. B-Students who are at the stage of early adolescence, second and third in the SCS are students who reported receiving more abuse on the part of teachers and exert more abuse towards them. C-Teenagers belonging to minority groups while less feel for their ethnicity and their quest for greater identity will be at higher risk of becoming involved in situations of school violence. D-Students victims of school violence are identified with feminine values, while students who are not involved in school violence integrated into their repertoire behavioral values female and male. This research work provides empirical evidence of the phenomenon of school violence from a broader context, not just confined to explore peer violence.

    Summary: This work has been aimed at analyzing the informal knowledge of the children of Early Childhood Education on numeracy. Participants included 36 children from Early Childhood Education divided into two age groups (ie, Group I: 4-5 years and Group II: 5-6 years) and longitudinal follow-up was conducted of children's Group I when they were 5-6 years. They resolved a protocol of 20 problems verbal addition, subtraction, multiplication, division partitiva and measurement division structure with action and no action, through individual interviews, which were taped for later analysis. In terms of results, the cross-sectional study carried out an ANOVA mixed 2 (Group: I and II) x 5 (Operation: vs. addendum. Vs. Abduction. Multiplication vs.división partitiva vs. Division average) x 2 (Type Problem ) with repeated measures over the last two factors and executed with SPSS. That analysis showed that the main effects were significant group (F 1.34 = 6,940. P less 0.05), Operation (R 4136 = 3,860, p less 0.01) and Problem type structure or semantics (F 1.34 = 183,165, p less 0.01). In addition, the longitudinal study conducted a second ANOVA 2 (Moment of Measurement: Measurement I vs. Measurement II) x 5 (Operation: adding theft vs. vs. vs. multiplication division partitiva vs. division measure) x 2 (Type Problem: vs. action no action) with repeated measures and carried out with SPSS. This analysis showed again that the main effects were significant factors of Measurement (F1, 14 = 6,000, p less 0.05), Operation (F4, 46 = 4,482, p less 0.01) and type Problem (F1, 14 = 101,083, p minor 0.01). These data, along with the quantitative analysis of the correct and incorrect procedures, we are led to conclude, among other things, that: - The operation was easier to resolve the division of measurement together with the addition in both groups and both studies (ietransversal and longitudinal). B-While 4-year-olds already had complex strategies such as memory, the frequency of use of more advanced strategies was higher in the group of 5 years, and the lower frequency of errors, such as procedural and enforcement. Overall, the largest group scored a better performance in solving problems resulting from the increased number of experiences "mathematics". Finally proof Wilconxon threw cough gives very interesting on the intraindividual variability, reaching up to ten children who improved their performance when they met 5 years.

    Summary: This thesis is an analysis about the perception of individual differences over history, segregation of persons with particular patterns of development and their relationship with the knowledge of the brain and neurodevelopmental processes. It shows that although you can see a step forward in the respect and attention to the diversity of styles perception, learning and mental states or behavioral and deepening the knowledge of the structure and functioning of the nervous system, there are few moments that an area has been nourished by the other. This research deals with the neurodevelopmental, diversity and segregation from the perspective of integrating knowledge of multiple disciplines, covering topics of genetic and epigenetic, neurodevelopmental, gestation, basic neuroscience, brain plasticity, epigenesis, perception, memory, learning, and neuropsychological functions higher cognitive, language, communication and resilience. We present evidence that supports that diversity is a trait common to all human beings, and that there is no scientific justification for the exclusion of those whose patterns of development are inconsistent with the expectations of society. It raises the development process as coevolutivo, ie not merely as a substrate product of genetic or environmental stimuli. It builds on the theory that segregation, understood as any factor or action that limits the relationship between the body and its environment, basic processes affect neurodevelopment and neuroevolución, both individually and collectively. The thesis is part of one of the overall objectives of the Neuropsicología: the study of the influence of experience on the substrate neurofuncional. It contributes to the analysis and understanding of the risk of segregation for neurodevelopmental processes, as well as the understanding of various factors that can potentially limit or promote it.

    Summary: The phenomenon of informal tutoring is evaluated through a system based on the unit of analysis of socio-mediated action and sensitive to the issues we disagree models of interpretation of the tutoring: diádica the definition of the task and the role of guardian and Trained in the process. When applied to the analysis of the interaction of 66 díadas adulta-niño / a (ages of the children range from 3 to 5 years and adults differ in the level of education and in the vicinity socioafectiva you have with your ninterlocutor child), a task multiple classification, makes it possible to identify key effectiveness tutorial microgenética to promote partner him less able to master the task as the voice adult. The evolutionary analysis of the interactions stimulants to distinguish variations associated with the age of some of the tutoring invariant evolutionary where its value lies stimulating. Moreover, data reveal that all the changes introduced by the proximity socioafectiva tutorial in the process promote its value inspiring, and that, which introduces him educated tutor, some are not relevant to the success tutorial and other optimize the effectiveness of process, exceeding the minimum rates required for interaction is stimulating and are guaranteed with low educational levels, which leads to the conclusion that lso cognitive resources with which interacts guardian, regardless of their level of development, are also the service of sociogénesis at least subject to compliance with conditions favorable intersubjectivity, aided by the proximity socioafectiva between partners.

    Summary: The dependencia-independencia field was the theme chosen for this work. This cognitive style, developed and promoted by Witkin is the dimension stylistic more extensive and long tradition of inquiry. Being in Portugal few studies on the cognitive styles, we intend to diversify the cognitive information used in the diagnosis of learning problems and the intervention of practical ways to promote cognitive skills and learning of students with the greatest difficulties. The study analyzed differences in cognitive performance associated with the DEC, considering three subgroups of students in terms of cognitive style: independent subjects in the field, depending on field and intermediate. Tests were applied atencionales and memory processes, as well as skills visuoperceptivas and visuoconstructivas. In analyzing the resutlados was controlled variability due to the intelligence. They confirmed that the subjects in a style dependent on cognitive difficulties in the field show cognitive functioning likely to be at the root of their problems in school performance. The next step in research would be to identify variables that are associated with school performance, thus allowing direct efforts toward intervention areas especially critical.

    Summary: INTRODUCTION The neuropsychological and neuroimaging studies provide data that subjects with a history of prematurity have a lower cognitive performance as well as a variety of structural brain abnormalities respect to those born at term. Objectives The objectives were to explore the memory deficits and their possible relation to IQ teen preterm low birth weight; studying abnormalities of the corpus callosum and cognitive performance in adolescents born preterm; explore the influence of gestational age at birth on the anomalies of the corpus callosum and the overall cognitive performance in the subjects mentioned above. We performed a neuropsychological and neuroimaging studies in a total sample of 83 teenagers premature. RESULTS Teenagers premature presented significant differences in memory daily, which disappears when taking into account the overall intelligence quotient (ILC). The gestational age is the variable clinical best predicts the ILC. Teenagers premature shows a reduction in the total size of the corpus callosum, and the genu, later midbody and splnium and performed worse in several cognitive functions. The gestational age correlated with the total corpus callosum and the ILC. Teenagers born before Week 27 presents a thinning of the corpus callosum total, as well as genu, earlier midbody, later midbody, isthmus and splenium and a low Cl. Subjects born between week 28 and 30, show a reduction in the splenium and low Cl. The infants born with EG between 31 and 33 weeks, only show a low Cl. The EG correlates with the corpus callosum and the Cl. CONCLUSIONS * Adolescents with a history of prematurity cognitive difficulties and structural abnormalities in the long term, most related to gestational ale dad with the birth weight. * Adolescents who were born prematurely have memory deficits that may explicares partially by their failures in cognitive performance. * Intelligence memory of everyday life, learning and verbal fluency verbal semantics, cognitive functions more sensitive to premturidad. * Even if observed statistically significant differences between the study groups, the extent of scores of subjects premature lies in the normal range. * The reduction in size of the corpus callosum, observed earlier in preterm infants, it remains as a minimum after 16 years of brain reorganization. * The genu later midbody and splenium, the subregions are most affected by prematurity. * The gestational age at birth presents a clear relationship with abnormalities of the corpus callosum and low cognitive performance.
