Classifier Learning

Mandarin classifiers are a complex system, but little is known about how Mandarin-speaking children manage to learn the system. Based on the extant literature, we explored potential factors influencing the comprehension and production of Mandarin shape classifiers, including classifier-based semantic categorization and errors pertaining to the semantic strategies, input frequency of classifier-noun combinations, and vocabulary knowledge. In total, 138 typically developing monolingual Mandarin-speaking children between ages 4;1 and 6;5 completed an object categorization task, shape classifier comprehension and production tasks, and a vocabulary test. The results showed that classifier-based categorization did not significantly relate to classifier knowledge, but children’s comprehension errors were mostly selecting an object that is perceptually similar to the target object. Estimated input frequency of classifier-noun combinations was significantly related to classifier comprehension, and there was differential accuracy for different classifier-noun combinations, which may indicate item-by-item learning of individual classifier-noun pairings. Mandarin-speaking children may take a combined approach by sorting semantic features for different classifiers and learning individual classifier-noun combinations. The interplay of the two approaches can be very complex and should be further investigated in future studies. Vocabulary knowledge was significantly related to classifier comprehension and production, indicating common traits between classifier learning and noun learning.

Down syndrome is associated with severe deficits in language and verbal short-term memory, but the causal relationship between these deficits is unclear. The current study therefore investigated the influence of language abilities on verbal short-term memory performance in Down syndrome. Twenty-one individuals with Down syndrome and 29 younger typically developing children were tested on memory for words and nonwords using 2 immediate recognition tasks: an order memory task that was a relatively pure measure of verbal short-term memory and an item memory task that was more sensitive to language ability. Despite having superior vocabulary knowledge to the typically developing children, individuals with Down syndrome were impaired on both order and item tasks. This impairment was particularly marked on the item task, where individuals with Down syndrome showed an atypically large lexicality effect. These results are interpreted in terms of an underlying verbal short-term memory deficit in Down syndrome that is compounded by poor phonological discrimination abilities.

AbstractWe can easily identify a dog merely by the sound of barking or an orange by its citrus scent. In this work, we study the neural underpinnings of how the brain combines bits of information into meaningful object representations. Modern theories of semantics posit that the meaning of words can be decomposed into a unique combination of individual semantic features (e.g., “barks”, “has citrus scent”). Here, participants received clues of individual objects in form of three isolated semantic features, given as verbal descriptions. We used machine-learning-based neural decoding to learn a mapping between individual semantic features and BOLD activation patterns. We discovered that the recorded brain patterns were best decoded using a combination of not only the three semantic features that were presented as clues, but a far richer set of semantic features typically linked to the target object. We conclude that our experimental protocol allowed us to observe how fragmented information is combined into a complete semantic representation of an object and suggest neuroanatomical underpinnings for this process.

We compared scanpath similarity in response to repeated presentations of social and nonsocial images representing natural scenes in a sample of 30 participants with autism spectrum disorder and 32 matched typically developing individuals. We used scanpath similarity (calculated using ScanMatch) as a novel measure of attentional bias or preference, which constrains eye-movement patterns by directing attention to specific visual or semantic features of the image. We found that, compared with the control group, scanpath similarity of participants with autism was significantly higher in response to nonsocial images, and significantly lower in response to social images. Moreover, scanpaths of participants with autism were more similar to scanpaths of other participants with autism in response to nonsocial images, and less similar in response to social images. Finally, we also found that in response to nonsocial images, scanpath similarity of participants with autism did not decline with stimulus repetition to the same extent as in the control group, which suggests more perseverative attention in the autism spectrum disorder group. These results show a preferential fixation on certain elements of social stimuli in typically developing individuals compared with individuals with autism, and on certain elements of nonsocial stimuli in the autism spectrum disorder group, compared with the typically developing group.

The Impact

This paper examines the influential factors of potential adoption of Enterprise Risk Management (ERM) and the impact of ERM adoption on the public listed banking firms’ performances in Indonesia during 2009 to 2017. This research uses logistic regression to test four potential factors as the driving forces behind the potential adoption of ERM and linear regression to test the impact of ERM on firms’ performances. The result suggests that firms with greater size, having more institutional ownership, and being part of Multinational companies are more likely to adopt ERM, while the implementation of ERM has no significant impact on the firms’ performance. Little empirical research has been conducted on the topic, especially in developing economies like Indonesia. This study will broaden the scope of literature by providing novel empirical evidence.

ABSTRACTPrevious studies show that young monolingual children's ability to ‘fast map’ new word forms is closely associated with both their age and existing vocabulary knowledge. In this study we investigate potential relationships between age, fast mapping skills and existing vocabulary knowledge in both languages of developing bilingual preschool children. Participants were twenty-six typically developing children, ages 3 ; 0 to 5 ; 3. All children learned Hmong as their primary home language (L1) and English as a second language (L2). Fast mapping and vocabulary knowledge tasks were administered in L1 and L2. For vocabulary knowledge, scores were comparable in L1 and L2; for fast mapping, scores were somewhat greater in L1 than L2. In contrast to previous findings with monolingual children, fast mapping performance was not related to age or existing vocabulary knowledge in either Hmong or English. There were, however, significant positive and negative cross-language correlations between L1 fast mapping and L2 vocabulary.

ABSTRACTThe effect of phonotactic probability (PP) and neighbourhood density (ND) on triggering word learning was examined in children with Language Impairment (3;04–6;09) and compared to Typically Developing children. Nonwords, varying PP and ND orthogonally, were presented in a story context and their learning tested using a referent identification task. Group comparisons with receptive vocabulary as a covariate found no group differences in overall scores or in the influence of PP or ND. Therefore, there was no evidence of atypical lexical or phonological processing. ‘Convergent’ PP/ND (High PP/High ND; Low PP/Low ND) was optimal for word learning in both groups. This bias interacted with vocabulary knowledge. ‘Divergent’ PP/ND word scores (High PP/Low ND; Low PP/High ND) were positively correlated with vocabulary so the ‘divergence disadvantage’ reduced as vocabulary knowledge grew; an interaction hypothesized to represent developmental changes in lexical–phonological processing linked to the emergence of phonological representations.

Purpose This study examined the unique and shared variance that nonword repetition and vocabulary knowledge contribute to children's ability to learn new words. Multiple measures of word learning were used to assess recall and recognition of phonological and semantic information. Method Fifty children, with a mean age of 8 years (range 5–12 years), completed experimental assessments of word learning and norm-referenced assessments of receptive and expressive vocabulary knowledge and nonword repetition skills. Hierarchical multiple regression analyses examined the variance in word learning that was explained by vocabulary knowledge and nonword repetition after controlling for chronological age. Results Together with chronological age, nonword repetition and vocabulary knowledge explained up to 44% of the variance in children's word learning. Nonword repetition was the stronger predictor of phonological recall, phonological recognition, and semantic recognition, whereas vocabulary knowledge was the stronger predictor of verbal semantic recall. Conclusions These findings extend the results of past studies indicating that both nonword repetition skill and existing vocabulary knowledge are important for new word learning, but the relative influence of each predictor depends on the way word learning is measured. Suggestions for further research involving typically developing children and children with language or reading impairments are discussed.

Word Characteristics

Definitions exhibit aspects of mental lexicon organization. Learners with Developmental Language Disorder (DLD) have limited vocabulary knowledge (in breadth and depth) and, thus, less mature definitional skills. Word characteristics affect the definitional skills. This study investigated the definitional skills of learners with and without DLD considering different word characteristics. Moreover, issues like deviant vs. delayed abilities and the link between breadth and depth of vocabulary knowledge are addressed. Thirty-six learners were divided into three groups (a DLD and two control groups [CG] of typically developing learners matched on either age or vocabulary). They were asked to define 16 words. Answers were scored for content and form. Findings revealed that the DLD group scored lower than both CGs in content, while no differences were found in form. Definitions of abstract and compound words were more demanding for all. Correlations between vocabulary and definitional skills were detected only in the age-matched CG. From the above, we deduce that DLD learners’ definitional skills are deviant. In addition, clinical practice should not look at effects of isolated variables, but rather investigate the interrelation of different parameters. Finally, the link between breadth and depth of vocabulary knowledge may require more time to emerge in DLD learners.

The Gaze

Children with autism spectrum disorder (ASD) display difficulties with response to joint attention in natural settings but often perform comparably to typically developing (TD) children in experimental studies of gaze following. Previous work comparing infants at elevated likelihood for ASD versus TD infants has manipulated aspects of the gaze cueing stimulus (e.g. eyes only versus head and eyes together), but the role the peripheral object being attended to is not known. In this study of infants at elevated likelihood of ASD ( N = 97) and TD infants ( N = 29), we manipulated whether or not a target object was present in the cued area. Performance was assessed at 10, 14, and 18 months, and diagnostic assessment was conducted at age 3 years. The results showed that although infants with later ASD followed gaze to the same extent as TD infants in all conditions, they displayed faster latencies back to the model’s face when (and only when) a peripheral object was absent. These subtle atypicalities in the gaze behaviors directly after gaze following may implicate a different appreciation of the communicative situation in infants with later ASD, despite their ostensively typical gaze following ability. Lay abstract During the first year of life, infants start to align their attention with that of other people. This ability is called joint attention and facilitates social learning and language development. Although children with autism spectrum disorder (ASD) are known to engage less in joint attention compared to other children, several experimental studies have shown that they follow other’s gaze (a requirement for visual joint attention) to the same extent as other children. In this study, infants’ eye movements were measured at age 10, 14, and 18 months while watching another person look in a certain direction. A target object was either present or absent in the direction of the other person’s gaze. Some of the infants were at elevated likelihood of ASD, due to having an older autistic sibling. At age 3 years, infants were assessed for a diagnosis of ASD. Results showed that infants who met diagnostic criteria at 3 years followed gaze to the same extent as other infants. However, they then looked back at the model faster than typically developing infants when no target object was present. When a target object was present, there was no difference between groups. These results may be in line with the view that directly after gaze following, infants with later ASD are less influenced by other people’s gaze when processing the common attentional focus. The study adds to our understanding of both the similarities and differences in looking behaviors between infants who later receive an ASD diagnosis and other infants.
