Temperamental profiles and language development: a replication and an extension

Individual differences in child temperament are associated with individual differences in language development. The present study examined the relationship between temperament and language ability in 109 twenty-four- to 30-month-old children. Parents and day-care teachers completed two questionnaires: the Primo Vocabolario del Bambino (Caselli & Casadio, 1995) and the Questionari Italiani del Temperamento (Axia, 2002). Researchers administered the First Language Test (Axia, 1993) to assess productive and receptive language in each child. Replicating previous research (Usai, Garello, & Viterbori, 2009), day-care teachers identified three temperamental profiles: most of the children fit into the first profile, typical of the Italian population; another profile was made up of easily distractible and not very persistent children, with a poor capacity to modulate motor activity; and the third profile of children were inhibited in new situations. A relationship was found between temperament assessed by day-care teachers and different levels of linguistic competence. In particular, the groups of "inattentive" and "inhibited" children showed poorer lexical and morphological abilities and a more immature vocabulary, characterised by the presence of more primitive components of the lexical repertory compared to the group of "typical" children. Unlike the results from day-care teachers, temperament questionnaires completed by parents revealed a 4-cluster-solution. Also, for parents, the "typical" profile is characterised by the largest vocabulary (productive and receptive) and the most mature semantic production.     

Føllesdal on the notion of the noema: A critique

Conclusion In this paper, I have demonstrated that Føllesdal's famous interpretation of Husserl's concept of the noema is mistaken due to a fundamental misunderstanding of Husserlian terminology. I have given what I consider to be a correct explanation of the notion of the noema and of Husserlian terminology and have backed my claims with direct references to the text. I have then compared and contrasted these with Føllesdal's interpretation and, thereby, have explained the nature of his mistakes with regards to terminology. I have also shown that two of Føllesdal's faithful followers, Smith and McIntyre, have walked a similarly erroneous path with regards to their interpretation of Husserl's theory of meaning in theIdeas.I do not know where the key to the reconciliation of phenomenology and analytic philosophy lies. But, I do know that it does not lie in the claim that Husserl shared Frege's view on the nature of meaning as an abstract intensionalSinn nor does it lie in the related view that Husserl radically changed his conception of the relation of meanings to intending acts. Hopefully, this paper has shed light on this widely debated issue and has clarified the nature of the mistakes in recent interpretations of Husserl's concept of the noema.     

Spanish-English L2 speakers' use of subcategorization bias information in the resolution of temporary ambiguity during second language reading

Using a self-paced moving window reading paradigm, we examine the degree to which structural commitments made while 60 Spanish-English L2 speakers read syntactically ambiguous sentences in their second language (L2) are constrained by the verb's lexical entry about its preferred structural environment (i.e., subcategorization bias). The ambiguity under investigation arises because a noun phrase immediately following a verb can be parsed as either the direct object of the verb 'The CIA director confirmed the rumor when he testified before Congress', or as the subject of an embedded complement 'The CIA director confirmed the rumor could mean a security leak'. In an experiment with 59 monolingual English participants, we replicate the findings reported in the previous literature demonstrating that native speakers are guided by subcategorization bias information during sentence interpretation. In a bilingual experiment, we then show that L2 subcategorization biases influence L2 sentence interpretation. The results indicate that L2 speakers keep track of the relative frequencies of verb-subcategorization alternatives and use this information when building structure in the L2.     

Phonological sensitivity and memory in children with a foreign language learning difficulty

The phonological processing and memory skills of 12- and 13-year-old Italian children with difficulty in learning English as a foreign language (foreign language learning difficulty, FLLD) were examined and compared with those of a control group matched for age and nonverbal intelligence. Three experiments were conducted. A dissociation between verbal and visuo-spatial working memory was observed when compared to the control group; children with FLLD showed a poorer performance in a phonological working memory task but performed to a comparable level in a visuo-spatial working memory task (Experiment 1). In Experiment 2 the word length and the response modality of an auditory word span task were manipulated in order to examine the efficiency of the phonological loop and the relevance of the spoken output. The FLLD group did not show sensitivity to the word length effect and showed no advantage in the picture pointing recall condition. In Experiment 3 children with FLLD were shown to be sensitive to phonological similarity but again they showed neither a word length effect nor a slower articulation speed. Furthermore, in all three experiments children with FLLD were shown to be less efficient in phonological sensitivity tasks and this deficit appeared to be independent of the phonological memory problem. All three experiments consistently showed that children with FLLD have an impairment in phonological memory and phonological processing, which appear to be independent from one other but both contribute to the children's difficulty in learning a second language.     

Temperamental profiles and linguistic development: Differences in the quality of linguistic production in relation to temperament in children of 28 months

The temperamental constellations that can be found in the infant population may influence the development trajectories of single domains of knowledge, such as that relative to language. The main objective of this study is to identify temperamental profiles to which one associates different levels of linguistic competence and to identify the profile associated with the highest risk for language acquisition. The temperamental characteristics of a sample of 106 children of 28 months attending day-care centres were surveyed and three temperamental profiles were highlighted: a profile typical of the Italian population which grouped most of the children; another made up of easily distractible and not very persistent children, who show a poor capacity to modulate motor activity and finally, the third with children inhibited in new situations. A comparison of the three groups on the basis of the level of linguistic competence revealed important differences regarding certain indices such as the vocabulary size and composition: in particular, the group of “inattentive” children has a more “immature” vocabulary composition, characterised by the presence of more primitive components of the lexical repertory.     

Neurofunctional correlates of personality traits in relapsing-remitting multiple sclerosis: An fMRI study

Extraversion and Neuroticism are two fundamental dimensions of human personality that influence cognitive functioning in healthy subjects. Little is known about personality changes that may occur in patients with multiple sclerosis (MS) nor about, in particular, their neurofunctional basis. The aim of this study is to determine the impact of personality characteristics on brain activity in patients with MS. Eighteen patients with clinically definite relapsing-remitting MS without any evidence of psychiatric or cognitive disorders and thirteen healthy controls matched for age, gender and education were investigated using functional magnetic resonance imaging (fMRI) during the execution of an “n-back” task. No differences were detected on the behavioral tests between the two groups, although the MS patients had lower total IQ and showed a trend towards higher Extraversion and Neuroticism scores than did the controls. fMRI analyses demonstrated that Extraversion scores were positively associated with brain activity in the fronto-parietal network including the superior parietal lobule and dorsolateral prefrontal cortex in both groups during the high load condition of the n-back task. Given the overlapping neural systems found in the two groups, we suggest that the neural activity associated with specific personality dimension is a neurophysiological characteristic preserved in patients with MS at an early stage in the course of their disease.     

Weighting of vowel cues explains patterns of word–object associative learning

Previous research has demonstrated that infants under 17 months have difficulty learning novel words in the laboratory when the words differ by only one consonant sound, irrespective of the magnitude of that difference. The current study explored whether 15‐month‐old infants can learn novel words that differ in only one vowel sound. The rich acoustic/phonetic properties of vowels allow for a detailed analysis of the contribution of acoustic/phonetic cues to infants’ performance with similar‐sounding words. Infants succeeded with the vowel pair /i/–/I/, but failed with vowel pairs /i/–/u/ and /I/–/u/. These results suggest that infants initially use the most salient acoustic cues for vowels and that this staged use of acoustic cues both predicts and explains why infants can learn some words that differ in only a single vowel.
