From residential care to school: peer relationships at school of minors in residential care

In this study, peer relationships of minors in residential care in a school context are analysed, both from the perspective of the peers and the teachers. Using a sociometric test and an evaluation protocol for teachers in 50 classrooms, a sample of 60 minors in care is compared to a normative sample of 843 minors. The results show that minors in residential care have a higher rate of rejection by their classmates in academic activities, but not for leisure ones. Furthermore, in comparison with the normative sample, they are more frequently described with negative adjectives. There is a high level of agreement between the peer evaluation and that of the teachers in the most visible aspects in the classroom. The implications of these results for the improvement of the adjustment of this group are discussed.     

Effects of Tradislexia videogame on phonological awareness and word recognition in dyslexic children

The purpose of this research was to analyze the effects of multimedia training on phonological awareness and word recognition in dyslexic children. We used a control pretest-posttest design, and a sample of 62 children (26 male, 36 female) was selected from Primary Education. Children were selected and classified into two different groups: (1) an experimental group (N=32), and (2) a control group (N=30). The average range age was 9 and 12 years (M=126.7, SD=11.7). We administered phonological awareness tasks, which include different types of syllabic structure from the Sicole-R Multimedia Battery for assessment of cognitive processes in reading. We analyzed whether the Tradislexia videogame affected phonological awareness, considering separately the complexity of syllable structure and type of phonological awareness task. We also analyzed whether the gains in phonological processes were related to training based on type of task or type of syllable structure. The results showed that when we controlled the position of phoneme, the multimedia treatment in segmentation and blending with words that include CV syllables is a better predictor to explain improvement of word decoding processes.     

Evaluation of three sensitivity measures in magnitude estimation tasks

Taking into account the studies about the measure of sensitivity in magnitude estimation tasks, we analyze the three most common measures used in this topic: Pearson's product-moment correlation between the logarithm of the stimulus and the logarithm of the response (R), the exponent of Stevens' power function (K), and the measure "M" proposed by Garriga-Trillo. Using a sample of participants greater than usual in psychophysical studies (180 participants), we designed an experiment with two sets of stimuli with different stimulus ranges. In each of these sets, we used two kinds of stimuli (line segments and squares). Our conclusions were: (1) we rejected the use of K as a sensitivity measure because the results provided by this index were the opposite of those expected when we compared the two stimulus ranges. (2) We also rejected the use of M because this measure is a linear transformation of Kendall's coefficient of concordance. (3) Lastly, we suggest the mathematical transformation proposed by Fisher to achieve a normal distribution, and recommend this transformation as the best sensitivity measure.     

Quality of life in transplant patients, compared to other stressful health situations in pulmonary patients

Transplantation may imply severe biopsychosocial impairments. In order to know the quality of life of patients one year after transplantation, 58 subjects were compared to three different groups of patients (stabilized and acute COPD patients, and lung cancer patients in a surgery unit). Patients filled in two questionnaires: EORTC QLQ-C30 (quality of life) and HAD (anxiety and depression). The quality of life dimensions with inter-group differences were physical, role, emotional and cognitive functioning, global health status, and a number of symptoms (fatigue, dyspnea, insomnia and appetite loss). There were differences in depression, and but not in anxiety. Transplant and surgical patients showed better quality of life and affective status than chronic pulmonary patients. Discriminant analysis showed that the transplant group was the best described group. We conclude that patients, one year after transplantation, show similar quality of life as asymptomatic hospitalised patients, somewhat better than chronic patients in a stabilized stage of the disease, and much better than severe chronic patients.     

Absence of hardly pursued updating in a running memory task

In a running memory span task, the participants are presented with a list of items (e.g. numbers or words) of an unknown length, because this length varies from trial to trial. In one variation of the procedure the participants must report a certain fixed number of items (e.g. four) from the end of the list. According to Morris and Jones (British Journal of Psychology, 81, 111-121, 1990), the recalled items must be updated in memory as the presentation of the list progresses. Ruiz, Elosúa and Lechuga (The Quarterly Journal of Experimental Psychology, 5, 887-905, 2005) noted that an active strategy implies an inhibition in memory of the final discarded items, and did not find results which supported this hypothesis. The aim of this study is to check whether or not participants adopt an active processing strategy in extreme conditions. Experiment 1 uses catch trials, which induce the participants not to discard the first items of the lists, and also short lists (of 4, 7, 8, 9 and 10 items); these could be considered optimal conditions for updating. However, it should also be pointed out that with an upper limit of 10 items per list, participants could try to memorise the whole list in most of the trials. One way to discourage this strategy is including lists well over span (e.g. 14-26 items). The purpose of Experiment 2 was to analyse the 10-item lists in two conditions: within a context of much longer lists (well over span) in most of the trials and within a context of shorter lists (data of Experiment 1). Results in both experiments, from the analysis of location errors, indicate that even in these conditions the participants do not seem to carry out the supposed active updating of the memory set.     

Cognitive and linguistic skills in Swedish children with cochlear implants - measures of accuracy and latency as indicators of development

The purpose of the present study was to examine working memory (WM) capacity, lexical access and phonological skills in 19 children with cochlear implants (CI) (5;7-13;4 years of age) attending grades 0-2, 4, 5 and 6 and to compare their performance with 56 children with normal hearing. Their performance was also studied in relation to demographic factors. The findings indicate that children with CI had visuospatial WM capacities equivalent to the comparison group. They had lower performance levels on most of the other cognitive tests. Significant differences between the groups were not found in all grades and a number of children with CI performed within 1 SD of the mean of their respective grade-matched comparison group on most of the cognitive measures. The differences between the groups were particularly prominent in tasks of phonological WM. The results are discussed with respect to the effects of cochlear implants on cognitive development.     

Methodological naturalism and epistemic internalism

Epistemic naturalism holds that the results or methodologies from the cognitive sciences are relevant to epistemology, and some have maintained that scientific methods are more compatible with externalist theories of justification than with internalist theories. But practically all discussions about naturalized epistemology are framed exclusively in terms of cognitive psychology, which is only one of the cognitive sciences. The question addressed in this essay is whether a commitment to naturalism really does favor externalism over internalism, and we offer reasons for thinking that naturalism in epistemology is compatible with both internalist and externalist conceptions of justification. We also argue that there are some distinctively internalist aims that are currently being studied scientifically and these notions, and others, should be studied by scientific methods. This essay is dedicated to Deborah Mayo, who has long advocated using error statistical techniques to analyze and resolve epistemological puzzles in the philosophy of science. This essay follows the same spirit by advocating that computational concepts and techniques be applied within the heart of traditional, analytic epistemology.     

The over-generalization problem: predicates rigidly signifying the “unnatural”

According to the simple proposal, a predicate is rigid iff it signifies the same property across the different possible worlds. The simple proposal has been claimed to suffer from an over-generalization problem. Assume that one can make sense of predicates signifying properties, and assume that trivialization concerns, to the effect that the notion would cover any predicate whatsoever, can be overcome. Still, the proposal would over-generalize, the worry has it, by covering predicates for artifactual, social, or evaluative properties, such as ‘is a knife,’ ‘is a bachelor,’ or ‘is funny.’ In defense, it is argued that rigidity for predicates as characterized plays the appropriate theoretical role, and that the contention that “unnatural” properties are not to be rigidly signified is ungrounded.     

Processing modifier-head agreement in reading: Evidence for a delayed effect of agreement

The present study examined whether type of inflectional case (semantic or grammatical) and phonological and morphological transparency affect the processing of Finnish modifier-head agreement in reading. Readers' eye movement patterns were registered. In Experiment 1, an agreeing modifier condition (agreement was transparent) was compared with a no-modifier condition, and in Experiment 2, similar constructions with opaque agreement were used. In both experiments, agreement was found to affect the processing of the target noun with some delay. In Experiment 3, unmarked and case-marked modifiers were used. The results again demonstrated a delayed agreement effect, ruling out the possibility that the agreement effects observed in Experiments 1 and 2 reflect a mere modifier-presence effect. We concluded that agreement exerts its effect at the level of syntactic integration but not at the level of lexical access.     

Higher-Order Unification: A structural relation between Huet's method and the one based on explicit substitutions

We compare two different styles of Higher-Order Unification (HOU): the classical HOU algorithm of Huet for the simply typed λ-calculus and HOU based on the λσ-calculus of explicit substitutions. For doing so, first, the original Huet algorithm for the simply typed λ-calculus with names is adapted to the language of the λ-calculus in de Bruijn's notation, since this is the notation used by the λσ-calculus. Afterwards, we introduce a new structural notation called unification tree, which eases the presentation of the subgoals generated by Huet's algorithm and its behaviour. The unification tree notation will be important for the comparison between Huet's algorithm and unification in the λσ-calculus whose derivations are presented into a structure called derivation tree. We prove that there exists an important structural correspondence between Huet's HOU and the λσ-HOU method: for each (sub-)problem in the unification tree there exists a counterpart in the derivation tree. This allows us to conclude that the λσ-HOU is a generalization of Huet's algorithm and that solutions computed by the latter are always computed by the former method.
