AbstractThe present study investigated the association between the taxonomic, thematic and combined (taxonomic-thematic) conditions during the lexical decision task in Kannada-English speaking bilingual children. Further, the study explored the nature of categorization skills in typically developing Kannada-English speaking bilingual children with respect to the taxonomy and thematic aspects across gender.Considered for the study were 20 preschool children including ten boys and ten girls in the age range of 4–5 years. A total of 50 pictures, including ten target, ten taxonomically related, ten thematically related and 20 distracters were taken from an internet source. Three tasks were introduced to examine the association of the pictures based on taxonomic, thematic and combined conditions. For the first and second task (considered as Experiment I), the children were expected to relate pictures based on taxonomic relationship followed by thematic relationship in the second task. For the final task (Experiment II), both relationships (taxonomic and thematic) were given for each target picture, and the children were expected to relate it with either one of them. Responses were scored and statistically analyzed.There was a significant difference in the performances between male and female children for the taxonomic condition but not for the other two tasks (i.e. thematic and combined conditions). The comparison across three conditions revealed that the performance of those children varied between the conditions. Further, on pair-wise comparison, there was a significant difference for both combined-thematic and combined-taxonomic conditions but not for taxonomic and thematic conditions.The study supports the phenomenon of “thematic to taxonomic shift”, which is found to be emerging in pre-school children. This occurs differently among male and female children. The preferences of thematic relation as opposed to taxonomic relation is highlighted in the present study.

Abstract This study investigates the effect of stress change during compound processing in Modern Greek. Twenty-five native speakers were tested in a cross-modal lexical decision task and a naming task in order to test for performance differences across stress-change vs. non-stress-change compounds. No statistically significant difference was found for the lexical decision task. However, the naming task showed a significant effect of stress change in compound processing, with the production of non-stress-change compounds showing facilitation. These results indicate that stress change is reflected in compound processing in Greek and underscore the importance of considering the interplay between specific tasks and the computational role of linguistic features.

Purpose The authors examined the effects of conceptual scoring on the performance of simultaneous and sequential bilinguals on standardized receptive and expressive vocabulary measures in English and Spanish. Method Participants included 40 English-speaking monolingual children, 39 simultaneous Spanish–English bilingual children, and 19 sequential bilingual children, ages 5–7. The children completed standardized receptive and expressive vocabulary measures in English and also in Spanish for those who were bilingual. After the standardized administration, bilingual children were given the opportunity to respond to missed items in their other language to obtain a conceptual score. Results Controlling for group differences in socioeconomic status (SES), both simultaneous and sequential bilingual children scored significantly below monolingual children on single-language measures of English receptive and expressive vocabulary. Conceptual scoring removed the significant difference between monolingual and simultaneous bilingual children in the receptive modality but not in the expressive modality; differences remained between monolingual and sequential bilingual children in both modalities. However, in both bilingual groups, conceptual scoring increased the proportion of children with vocabulary scores within the average range. Conclusion Conceptual scoring does not fully ameliorate the bias inherent in single-language standardized vocabulary measures for bilingual children, but the procedures employed here may assist in ruling out vocabulary deficits, particularly in typically developing simultaneous bilingual children.

The issue of language selectivity regarding lexical access of bilingual adults has been thoroughly reported in the literature. However, studies with bilingual children are still limited, especially in the Brazilian context. To fill this gap, the present study was conducted with the goal of investigating whether the same cognate facilitation effect reported for bilingual adults is also true for bilingual children. To do so, two experiments were carried out. In Experiment 1, 53 Portuguese-English bilingual children from 3rd and 7th grade took part in a lexical decision task which had a Portuguese and an English version. In Experiment 2, 18 English monolinguals performed the English version of the lexical decision task. The results of Experiment 1 showed that the cognate effect was evident for the two groups of bilinguals when the task was performed in the L2- English, even though no statistical difference between the two groups of bilinguals was found. When performing the task in the L1 – Portuguese, the bilingual groups showed no cognate effect, which suggests that these participants had not reached a level of proficiency in which the L2 can influence L1 processing. The results of Experiment 2 showed no cognate facilitation effect for monolinguals, indicating that the results of the bilingual participants, in the English version of the lexical decision task, were indeed due to the cognate status of the words of the bilingual's two languages. In short, the present results favor the nonselective view of lexical access and the effect of proficiency in the perception of cross language similarity.

Purpose: There is a paucity of information detailing the phonological skills of Spanish-English bilingual children and comparing that information to information concerning the phonological skills of predominantly English-speaking (PE) and predominantly Spanish-speaking (PS) children. The purpose of this study was to examine the relationship between amount of output (i.e., percentage of time each language was spoken) in each language and phonological skills in Spanish-English bilingual children and PE and PS children. Method: Fifteen typically developing children, ranging in age from 5;0 (years;months) to 5;5 (mean=5;2), participated in the study. The participants consisted of 5 PE speakers, 5 PS speakers, and 5 bilingual (Spanish-English) speakers. A single-word assessment was used to gather information on phonological skills (consonant accuracy, type and frequency of substitutions, frequency of occurrence of phonological patterns [e.g., cluster reduction], accuracy of syllable types [e.g., CV, CVC, CCV, etc.]), and type and rate of cross-linguistic effects. Results: The results indicated that there was no significant correlation between amount of output in each language and phonological skills either in the Spanish skills of PS children and Spanish-English bilingual speakers or in the English skills of PE children and Spanish-English bilingual speakers. In addition, there was no significant difference in segmental accuracy, syllabic accuracy, or percentage of occurrence of phonological patterns between either the Spanish skills of PS children and Spanish-English bilingual speakers or the English skills of PE children and Spanish-English bilingual speakers. Finally, the children showed a limited number of cross-linguistic effects. Clinical Implications: Results from this study indicate no link between parent estimates of language output and phonological skill and demonstrate that Spanish-English bilingual children will have commensurate, although not identical, phonological skills as compared to age-matched PS and PE children.

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

Abstract. The ability to identify and communicate emotions is essential to psychological well-being. Yet research focusing exclusively on emotion concepts has been limited. This study examined nouns that represent emotions (e.g., pleasure, guilt) in comparison to nouns that represent abstract (e.g., wisdom, failure) and concrete entities (e.g., flower, coffin). Twenty-five healthy participants completed a lexical decision task. Event-related potential (ERP) data showed that emotion nouns elicited less pronounced N400 than both abstract and concrete nouns. Further, N400 amplitude differences between emotion and concrete nouns were evident in both hemispheres, whereas the differences between emotion and abstract nouns had a left-lateralized distribution. These findings suggest representational distinctions, possibly in both verbal and imagery systems, between emotion concepts versus other concepts, implications of which for theories of affect representations and for research on affect disorders merit further investigation.
