Children’s sociocultural experiences in their day-to-day lives markedly play a key role in learning about the world. This study investigated parent–child teaching during early childhood as it naturally occurs in the home setting. Thirty-nine families’ naturalistic interactions in the home setting were observed; 1033 teaching sequences were identified based on detailed transcriptions of verbal and non-verbal behavior. Within these sequences, three domains of learning (knowledge, skills, and dispositions) and subtopics were identified and analyzed in relation to gender, child birth order, (...) context, teaching strategies, and learner response. Findings show knowledge, skills, and dispositions were taught equally, marked by the most prominent subtopics taught within each domain, including cognitive (skill), game rule (knowledge), and social rule (disposition). Further, mothers and fathers were found to teach their children equally, however, fathers taught knowledge more than mothers, whereas mothers taught dispositions more than fathers. Differences between domains of learning and subtopics also existed between mother’s and father’s teaching based on child birth order and gender. This study also assessed the contrast between teaching knowledge, skills, and dispositions by context, parent teaching strategies, and child learner response. Results support the notion that family interactions in the home setting set a stage for children’s rich informal learning experiences. Vygotskian sociocultural conceptions underpin this research and findings are discussed using this central theoretical lens. (shrink)

This paper reports a study of planning processes in the five-disc Tower of London (TOL) task in 20 younger and 20 older adult participants. A concurrent direct ''think-aloud'' method was used to obtain data on planning processes prior to moving discs in the TOL. A check was made of the effects of verbalising by comparing performance data from the experimental groups with data from control groups who did not verbalise during planning or moving. Verbalising slowed down planning and moving but (...) did not appear to distort the participants' approaches to the task. Older and younger participants did not differ in average moves taken to solve the tasks. However, older participants' planning was less complete and more error-prone than that of younger participants. The planning processes were characterised as showing a means-ends ''goal selection'' strategy. In this strategy participants (1) identify a single active goal disc at the start, (2) select moves and move sequences to enable the placing of the current goal disc in its target position, and (3) continue in this way until all discs are in their target positions. Age differences were found in the planning stage, during which there was no stimulus support and hence a substantial working memory load. During the move phase there was stimulus support and hence little loading of working memory. Age differences in moves required were not found in the move phase. As older participants tend to have depleted working memory capacity the present results suggest that working memory is heavily loaded in TOL planning but less so in the move phase of TOL. (shrink)

Cette étude se propose de vérifier l’efficacité des collocations en tant qu’indice pour distinguer les genres textuels. De plus, elle a le double objectif d’aborder l’exploration de la variabilité de l’italien en utilisant des méthodologies computationnelles, et de vérifier l’efficacité d’une nouvelle mesure d’association dans l’étude des collocations.Quatre typologies de collocations ont été analysées (verbe-nom, nom-adjectif, nom-nom et nom-préposition-nom) dans six genres textuels différents, dont trois sont écrits (textes littéraires, textes académiques et compositions scolaires) et trois sont oraux (conversations, discours (...) et dialogues filmiques).La fréquence des collocations dans les différents genres montre que chaque typologie de texte a des préférences spécifiques pour des typologies de collocations spécifiques; la seule fréquence et la seule distinction entre textes écrits et oraux, toutefois, ne réussit pas à interpréter cette différente distribution selon un modèle cohérent. A cet effet, la mesure statistique de la gravité lexicale semble posséder une efficacité majeure, comme nous essayerons de démontrer. (shrink)

This paper reports a study of the roles of visuo-spatial and verbal working memory capacities in solving a planning task - the five-disc Tower of London (TOL) task. An individual differences approach was taken. Sixty adult participants were tested on 20 TOL tasks of varying difficulty. Total moves over the 20 TOL tasks was taken as a measure of performance. Participants were also assessed on measures of fluid intelligence (Raven's matrices), verbal short-term storage (Digit span), verbal working memory span (Silly (...) Sentence span), visuo-spatial short-term storage (Visual Pattern span and Corsi Block span), visuo-spatial working memory (Corsi Distance Estimation), visuo-spatial processing speed (Manikin test), and verbal speed (Rehearsal speed). Exploratory factor analysis using an oblique rotation method revealed three factors which were interpreted as (1) a visuo-spatial working memory factor, (2) an age-speed factor, and (3) a verbal working memory factor. The visuo-spatial and verbal factors were only moderately correlated. Performance on the TOL task loaded on the visuo-spatial factor but did not load on the other factors. It is concluded that the predominant goal-selection strategy adopted in solving the TOL relies on visuo-spatial working memory capacity and particularly involves the active ''inner scribe'' spatial rehearsal mechanism. These correlational analyses confirm and extend results previously obtained by use of dual task methods, (Phillips, Wynn, Gilhooly, Della Sala, & Logie, 1999). (shrink)

Questo contributo teorico propone una prospettiva innovativa nel dibattito sul concetto di “bullshit”. L’ipotesi principale è che la vaghezza sia un elemento fondamentale delle bullshit, che si focalizza sull’attività. In questo modo si supera il dibattito in letteratura che mette al centro o l’intenzionalità dell’enunciatore o la struttura e il contenuto degli enunciati. Si sostiene inoltre che la vaghezza non debba essere considerata come un limite, ma come un’opportunità per comprendere situazioni comunicative complesse. Questo differente approccio, basato sulla tradizione pragmatista, (...) supera alcuni limiti evidenziati in letteratura, aprendo la strada a una comprensione più approfondita del fenomeno delle bullshit. Offre inoltre una risposta esaustiva ad alcuni quesiti di Frankfurt e riconosce il lato “produttivo” delle bullshit, adattandosi meglio a molteplici circostanze quotidiane. Un approccio pragmatista al fenomeno-bullshit basato sulla vaghezza offre una maggiore comprensione di fenomeni complessi di comunicazione senza cadere nel “paradigma della sincerità” evidenziato da Frankfurt.
