Differential effects of internal and external factors on the development of vocabulary, tense morphology and morpho-syntax in successive bilingual children
The present study investigates the effects of child internal (age/time) and child external/environmental factors on the development of a wide range of language domains in successive bilingual (L2) Turkish-English children of homogeneously low SES. Forty-three L2 children were tested on standardized assessments examining the acquisition of vocabulary and morpho-syntax. The L2 children exhibited a differential acquisition of the various domains: they were better on the general comprehension of grammar and tense morphology and less accurate on the acquisition of vocabulary and (complex) morpho-syntax. Profile effects were confirmed by the differential effects of internal and external factors on the language domains. The development of vocabulary and complex syntax were affected by internal and external factors, whereas external factors had no contribution to the development of tense morphology. These results are discussed in light of previous studies on the impact of internal and external factors in child L2 acquisition
Providing some more pieces to the puzzle: L2 adults, L2 children and children with Specific Language Impairment
Although the role of parsing for language acquisition has long been recognized (e.g., Fodor, 1998), empirical research on sentence processing in populations whose language abilities are still developing was sparse until about fifteen years ago when Clahsen and colleagues conducted the project âThe development of language processingâ. This led to a series of influential studies on sentence processing in monolingual (L1) children (Felser, Marinis, & Clahsen, 2003a; Roberts, Marinis, & Clahsen, 2007) and adult second language (L2) learners (Felser, Roberts, Marinis, & Gross, 2003b; Felser & Roberts, 2007; Marinis, Roberts, Felser, & Clahsen, 2005) and the formulation of the Shallow Surface Hypothesis (SSH) (Clahsen & Felser, 2006). The SSH sparked controversy in L2 acquisition research and led to the explosion of language processing studies in adult L2 learners, many of which are presented in the keynote paper by Phillips & Ehrenhofer (2015) (henceforth P&E). Compared to adult L2 processing research, research on language processing in L1 children is still limited, and even more limited are studies on processing in L2 children and children with Specific Language Impairment (SLI). Research in these populations is crucial if we want to understand the role of language processing in language acquisition, which is the aim of P&Eâs keynote paper. In this commentary I will add some more pieces to the puzzle P&E address by reporting recent findings on the role of immersion in adult L2 processing and discussing results on language processing in L2 children and children with SLI in relation to reanalysis and predictive parsing. The paper will conclude with a note on the need to compare on-Ââline comprehension with production.publishe

Decision-making capacity in aphasia: SLTâs contribution in England
Background: Individualsâ right to be involved with decisions regarding their health and social care is the cornerstone for modern patient-centred care. Decision-making is a complex process that involves multiple cognitive and linguistic abilities. These are often challenging for people with aphasia (PWA). The Mental Capacity Act (MCA) Code of Practice (2007) recommends that speech and language therapists (SLTs) support capacity assessments for individuals with communication problems, such as PWA. To date, little is known regarding SLTsâ involvement in the UK for supporting decision-making and capacity assessment for PWA.
Aims: This research provides data to document when, how, and the extent to which SLTs are being used in capacity assessment for PWA in England. We also determined SLTsâ training and resource needs in capacity assessments, and their role in inter-professional training.
Methods & Procedures: 56 SLTs working with PWA from a wide range of clinical settings in England were recruited; they completed a secure questionnaire using the online survey tool Survey Monkey. The questionnaire collected information in the following areas: knowledge and awareness of the MCA; current involvement of SLTs in capacity assessments and decision-making; inter-professional understanding of SLTs roles in capacity assessments; and training needs of SLTs.
Outcomes & Results: The SLTs who participated in this survey indicated that they were not regularly involved to support capacity assessment for PWA. Moreover, they also reported that other professionals on the care team did not fully recognise or utilise their skills in supporting capacity assessment for PWA. Moreover, SLTs were not solicited to train professionals regarding communication difficulties in aphasia and its impact on capacity assessments. SLTs wanted profession-specific training to fulfil the role of supporting PWA in capacity assessments more effectively and reliably.
Conclusions: Healthcare professionals have an ethical duty to ensure that judgements of capacity are unbiased and accurate. SLTs have an important contribution to make but their skills and knowledge are not fully recognised or utilised. These findings highlight an important need to raise the profile of SLTsâ skills and expertise amongst professionals through education and/or inter-professional communications. This would enable SLTs to be regularly and effectively utilised in capacity assessments and decision-making for PWA

Acquiring possessives
The concepts of possession and ownership are among the first to be expressed by children when they start acquiring language. This chapter starts with an overview of the properties of possession cross-linguistically followed by a review of the literature on the acquisition of possession in five languagesâEnglish, German, Greek, Hebrew, and Japanese. The studies on the acquisition of possession are discussed in relation to learnability issues and avenues are identified for future research on the acquisition of possession.</p
Syntactic complexity in the comprehension of wh-questions and relative clauses in typical language development and autism
This study investigates effects of syntactic complexity operationalised in terms of movement, intervention and (NP) feature similarity in the development of Aâ dependencies in 4-, 6-, and 8-year old typically developing (TD) French children and children with Autism Spectrum Disorders (ASD). Children completed an off-line comprehension task testing eight syntactic structures classified in four levels of complexity: Level 0: No Movement; Level 1: Movement without (configurational) Intervention; Level 2: Movement with Intervention from an element which is maximally different or featurally âdisjointâ (mismatched in both lexical NP restriction and number); Level 3: Movement with Intervention from an element similar in one feature or featurally âintersectingâ (matched in lexical NP restriction, mismatched in number). The results show that syntactic complexity affects TD children across the three age groups, but also indicate developmental differences between these groups. Movement affected all three groups in a similar way, but intervention effects in intersection cases were stronger in younger than older children, with NP feature similarity affecting only 4-year olds. Complexity effects created by the similarity in lexical restriction of an intervener thus appear to be overcome early in development, arguably thanks to other differences of this intervener (which was mismatched in number). Children with ASD performed less well than the TD children although they were matched on non-verbal reasoning. Overall, syntactic complexity affected their performance in a similar way as in their TD controls, but their performance correlated with non-verbal abilities rather than age, suggesting that their grammatical development does not follow the smooth relation to age that is found in TD children

Syntax and its interfaces at the low and high ends of the autistic spectrum
Studies on the language abilities in autism spectrum disorders (ASD) have tended to include individuals across the spectrum, with the consequence that the ensuing picture is rarely clear. Most recent studies setting apart individuals at the lower end of the autism spectrum have discovered severe problems in certain areas of grammar.
Investigation of grammatical abilities at the higher end of the spectrum has not identified severe problems so far, in an interesting contrast with the lower end. Here we report on current research on pronominal object clitics and their counterpart DPs, which demonstrates that, in some syntactic environments, high-functioning children with ASD fall behind typically developing children. We claim that this behavior does not reflect problems with syntax proper, but is a consequence of pragmatic shortcomings with consequences for the syntax-pragmatics interface. Errors of substitution of clitics with their corresponding DPs are likely to be caused by difficulties in detecting prominence in the discourse. Difficulties with Focused DPs are likely to be caused by problems in distinguishing old from new information and its mapping to prosody. Future research needs to investigate pragmatics, syntax and prosody independently, in order to reach solid conclusions regarding their interaction with respect to specific phenomena in autism, which, in turn, provides an ideal condition to test the contribution of each domain to these phenomena
Lexical and cognitive underpinnings of verbal fluency: evidence from Bengali-English bilingual aphasia
Research in bilingual healthy controls (BHC) has illustrated that detailed characterization of verbal fluency along with separate measures of executive control stand to inform our understanding of the lexical and cognitive underpinnings of the task. Such data are currently lacking in bilinguals with aphasia (BWA). We aimed to compare the characteristics of verbal fluency performance (semantic, letter) in BengaliâEnglish BWA and BHC, in terms of cross-linguistic differences, variation on the parameters of bilingualism, and cognitive underpinnings. BWA showed significant differences on verbal fluency variables where executive control demands were higher (fluency difference score, number of switches, between-cluster pauses); whilst performed similarly on variables where executive control demands were lower (cluster size, within-cluster pauses). Despite clear cross-linguistic advantage in Bengali for BHC, no cross-linguistic differences were noted in BWA. BWA who were most affected in the independent executive control measures also showed greater impairment in letter fluency condition. Correlation analyses revealed a significant relationship for BWA between inhibitory control and number of correct responses, initial retrieval time, and number of switches. This research contributes to the debate of underlying mechanisms of word retrieval deficits in aphasia, and adds to the nascent literature of BWA in South Asian languages
