Analyzing complexity in foreign language monologic oral production in a CLIL context

The study tested three analytic tools applied in SLA research (T-unit, AS-unit and Idea-unit) against FL learner monologic oral data. The objective was to analyse their effectiveness for the assessment of complexity of learners' academic production in English. The data were learners' individual productions gathered during the implementation of a CLIL teaching sequence on Natural Sciences in a Catalan state secondary school. The analysis showed that only AS-unit was easily applicable and highly effective in segmenting the data and taking complexity measures

Neural activity of the anterior insula in emotional processing depends on the individuals' emotional susceptibility

Differences in personality factors between individuals may manifest themselves with different patterns of neural activity while individuals process stimuli with emotional content. We attempted to verify this hypothesis by investigating emotional susceptibility (ES), a specific emotional trait of the human personality defined as the tendency to "experience feelings of discomfort, helplessness, inadequacy and vulnerability" after exposure to stimuli with emotional valence. By administering a questionnaire evaluating the individuals' ES, we selected two groups of participants with high and low ES respectively. Then, we used functional magnetic resonance imaging to investigate differences between the groups in the neural activity involved while they were processing emotional stimuli in an explicit (focusing on the content of the stimuli) or an incidental (focusing on spatial features of the stimuli, irrespectively of their content) way. The results showed a selective difference in brain activity between groups only in the explicit processing of the emotional stimuli: bilateral activity of the anterior insula was present in subjects with high ES but not in subjects with low ES. This difference in neural activity within the anterior insula proved to be purely functional since no brain morphological differences were found between groups, as assessed by a voxel-based morphometry analysis. Although the role of the anterior insula in the processing of contexts perceived as emotionally salient is well established, the present study provides the first evidence of a modulation of the insular activity depending on the individuals' ES trait of personality.

Creació d’un programari per a l’avaluació de la qualitat dels resultats analítics generats al laboratori

La validació de mètodes és un dels pilars fonamentals de l’assegurament de la qualitat en els laboratoris d’anàlisi, tal i com queda reflectit en la norma ISO/IEC 17025. És, per tant, un aspecte que cal abordar en els plans d’estudis dels presents i dels futurs graus en Química. Existeix molta bibliografia relativa a la validació de mètodes, però molt sovint aquesta s’utilitza poc, degut a la dificultat manifesta de processar tota la informació disponible i aplicar-la al laboratori i als problemes concrets. Una altra de les limitacions en aquest camps és la manca de programaris adaptats a les necessitats del laboratori. Moltes de les rutines estadístiques que es fan servir en la validació de mètodes són adaptacions fetes amb Microsoft Excel o venen incorporades en paquets estadístics gegants, amb un alt grau de complexitat. És per aquest motiu que l’objectiu del projecte ha estat generar un programari per la validació de mètodes i l’assegurament de la qualitat dels resultats analítics, que incorporés únicament les rutines necessàries. Específicament, el programari incorpora les funcions estadístiques necessàries per a verificar l’exactitud i avaluar la precisió d’un mètode analític. El llenguatge de programació triat ha estat el Java en la seva versió 6. La part de creació del programari ha constat de les següents etapes: recollida de requisits, anàlisi dels requisits, disseny del programari en mòduls, programació d les funcions del programa i de la interfície gràfica, creació de tests d’integració i prova amb usuaris reals, i, finalment, la posada en funcionament del programari (creació de l’instal·lador i distribució del programari).

ATiPAP : desenvolupament de materials docents amb suport multimedia pels continguts d'Atenció, Percepció Auditiva i de la Parla adaptats als crédits ECTS i a l'EEES dins l'ensenyament de Psicologia

El projecte ha permès finançar el suport tècnic necessari per a poder desenvolupar materials informatitzats corresponents a activitats teòrico-pràctiques de l’assignatura troncal de la llicenciatura de Psicologia (actualment també en el Grau) “Percepció i Atenció”. Els materials desenvolupats corresponen a diferents punts del programa de l’assignatura i són els següents: demostració de la tècnica d’ombrejat per l’anàlisi de l’atenció focalitzada; parpelleig atencional en sèries de presentacions ràpides d’informació visual (RSVP); canvis encoberts de l’atenció i el mecanisme d’inhibició de retorn; efectes dels filtrats sobre la percepció de la parla i la música; il·lusions auditives i els principis d’organització de la informació sonora complexa; la percepció categòrica dels sons de la parla i la naturalesa continua del processament lèxic (paradigma d’obertura successiva o gating). Per totes aquelles activitats amb continguts de llenguatge, s’han desenvolupat dues versions equivalents, catalana i castellana, per permetre que els estudiants fessin la pràctica en la seva llengua dominant. A la primera fase del projecte, al llarg del curs 2006-07, es van preparar els materials i la programació de les diferents pràctiques i es van poder identificar alguns problemes que es van solucionar posteriorment. En el curs 2007-08 totes les activitats de pràctiques ja es van fer accessibles als estudiants (Plataforma Moodle, Campus Virtual) i la valoració sobre el seu funcionament, feta pels estudiants mitjançant qüestionaris, va ser satisfactòria en més d’un 95% dels casos (els únics problemes detectats estaven relacionats amb les característiques dels ordinadors del usuaris i del navegador utilitzat per accedir als materials). La valoració de les activitats per part dels estudiants va ser globalment positiva i, en el seu ús continuat al llarg dels cursos 2008-09 i 2009-10, s’ha observat una participació creixent (accés voluntari a les activitats) i un aprofitament millor de la informació presentada, que es tradueix en millores en les puntuacions obtingudes en les avaluacions de l'assignatura.

Inadequate and infrequent are not alike : ERPs to deviant prosodic patterns in spoken sentence comprehension

The current study on German investigates Event-Related brain Potentials (ERPs) for the perception of sentences with intonations which are infrequent (i.e. vocatives) or inadequate in daily conversation. These ERPs are compared to the processing correlates for sentences in which the syntax-to-prosody relations are congruent and used frequently during communication. Results show that perceiving an adequate but infrequent prosodic structure does not result in the same brain responses as encountering an inadequate prosodic pattern. While an early negative-going ERP followed by an N400 were observed for both the infrequent and the inadequate syntax-to-prosody association, only the inadequate intonation also elicits a P600.

How multiple repetitions influence the processing of self-, famous and unknown names and faces: an ERP study.

Because we live in an extremely complex social environment, people require the ability to memorize hundreds or thousands of social stimuli. The aim of this study was to investigate the effect of multiple repetitions on the processing of names and faces varying in terms of pre-experimental familiarity. We measured both behavioral and electrophysiological responses to self-, famous and unknown names and faces in three phases of the experiment (in every phase, each type of stimuli was repeated a pre-determined number of times). We found that the negative brain potential in posterior scalp sites observed approximately 170 ms after the stimulus onset (N170) was insensitive to pre-experimental familiarity but showed slight enhancement with each repetition. The negative wave in the inferior-temporal regions observed at approximately 250 ms (N250) was affected by both pre-experimental (famous>unknown) and intra-experimental familiarity (the more repetitions, the larger N250). In addition, N170 and N250 for names were larger in the left inferior-temporal region, whereas right-hemispheric or bilateral patterns of activity for faces were observed. The subsequent presentations of famous and unknown names and faces were also associated with higher amplitudes of the positive waveform in the central-parietal sites analyzed in the 320-900 ms time-window (P300). In contrast, P300 remained unchanged after the subsequent presentations of self-name and self-face. Moreover, the P300 for unknown faces grew more quickly than for unknown names. The latter suggests that the process of learning faces is more effective than learning names, possibly because faces carry more semantic information.

Fingermark Detection on Thermal Papers: Proposition of an Updated Processing Sequence

The detection of latent fingermarks on thermal papers proves to be particularly challenging because the application of conventional detection techniques may turn the sample dark grey or black, thus preventing the observation of fingermarks. Various approaches aiming at avoiding or solving this problem have been suggested. However, in view of the many propositions available in the literature, it gets difficult to choose the most advantageous method and to decide which processing sequence should be followed when dealing with a thermal paper. In this study, 19 detection techniques adapted to the processing of thermal papers were assessed individually and then were compared to each other. An updated processing sequence, assessed through a pseudo-operational test, is suggested.

Hemispheric processing of differently valenced and self-relevant attachment words in middle-aged married and separated individuals

The reliance in experimental psychology on testing undergraduate populations with relatively little life experience, and/or ambiguously valenced stimuli with varying degrees of self-relevance, may have contributed to inconsistent findings in the literature on the valence hypothesis. To control for these potential limitations, the current study assessed lateralised lexical decisions for positive and negative attachment words in 40 middle-aged male and female participants. Self-relevance was manipulated in two ways: by testing currently married compared with previously married individuals and by assessing self-relevance ratings individually for each word. Results replicated a left hemisphere advantage for lexical decisions and a processing advantage of emotional over neutral words but did not support the valence hypothesis. Positive attachment words yielded a processing advantage over neutral words in the right hemisphere, while emotional words (irrespective of valence) yielded a processing advantage over neutral words in the left hemisphere. Both self-relevance manipulations were unrelated to lateralised performance. The role of participant sex and age in emotion processing are discussed as potential modulators of the present findings.
