Word Order Typology Interacts With Linguistic Complexity: A Cross-Linguistic Corpus Study

Much previous work has suggested that word order preferences across languages can be explained by the dependency distance minimization constraint (Ferrer-i Cancho, 2008, 2015; Hawkins, 1994). Consistent with this claim, corpus studies have shown that the average distance between a head (e.g., verb) and its dependent (e.g., noun) tends to be short cross-linguistically (Ferrer-i Cancho, 2014; Futrell, Mahowald, & Gibson, 2015; Liu, Xu, & Liang, 2017). This implies that on average languages avoid inefficient or complex structures for simpler structures. But a number of studies in psycholinguistics (Konieczny, 2000; Levy & Keller, 2013; Vasishth, Suckow, Lewis, & Kern, 2010) show that the comprehension system can adapt to the typological properties of a language, for example, verb-final order, leading to more complex structures, for example, having longer linear distance between a head and its dependent. In this paper, we conduct a corpus study for a group of 38 languages, which were either Subject–Verb–Object (SVO) or Subject–Object–Verb (SOV), in order to investigate the role of word order typology in determining syntactic complexity. We present results aggregated across all dependency types, as well as for specific verbal (objects, indirect objects, and adjuncts) and nonverbal (nominal, adjectival, and adverbial) dependencies. The results suggest that dependency distance in a language is determined by the default word order of a language, and crucially, the direction of a dependency (whether the head precedes the dependent or follows it; e.g., whether the noun precedes the verb or follows it). Particularly we show that in SOV languages (e.g., Hindi, Korean) as well as SVO languages (e.g., English, Spanish), longer linear distance (measured as number of words) between head and dependent arises in structures when they mirror the default word order of the language. In addition to showing results on linear distance, we also investigate the influence of word order typology on hierarchical distance (HD; measured as number of heads between head and dependent). The results for HD are similar to that of linear distance. At the same time, in comparison to linear distance, the influence of adaptability on HD seems less strong. In particular, the results show that most languages tend to avoid greater structural depth. Together, these results show evidence for “limited adaptability” to the default word order preferences in a language. Our results support a large body of work in the processing literature that highlights the importance of linguistic exposure and its interaction with working memory constraints in determining sentence complexity. Our results also point to the possible role of other factors such as the morphological richness of a language and a multifactor account of sentence complexity remains a promising area for future investigation.     

Epistemic Privilege and Victims’ Duties to Resist their Oppression

Victims of injustice are prominent protagonists in efforts to resist injustice. I argue that they have a duty to do so. Extant accounts of victims’ duties primarily cast these duties as self‐regarding duties (say, of Kantian self‐respect) or duties based on collective identities and commitments. I provide an account of victims’ duties to resist injustice that is grounded in the duty to assist. I argue that victims are epistemically privileged with respect to injustice and are therefore uniquely positioned to assist fellow victims. Primarily, they discharge this duty through testimony: victims alert other actors to the need for assistance and initiate and coordinate resistance efforts. I briefly provide an account of oppression that ranges from persecution to structural injustice. Through the examples of torture and ‘manterrupting’, I illustrate the duty and its limits. I outline shortcomings in victims’ epistemic privilege and explore means by which these can be overcome. I respond to objections from demandingness and fairness, arguing that victims have an essential, albeit circumscribed, role to play in defeating injustice.     

Impact of Caregiver Factors on Youth Service Utilization of Trauma-Focused Cognitive Behavioral Therapy in a Community Setting

Trauma-Focused Cognitive Behavioral Therapy (TF-CBT) is an increasingly available evidence-based therapy that targets the mental health symptoms of youth who have experienced trauma. Limited research has examined how to engage and retain families in TF-CBT services in community settings. Using a mixed-methods approach, the goal of this exploratory study was to identify caregiver factors that impact youth enrollment and completion of community-delivered TF-CBT. The study included 41 caretakers of youth referred to therapy at a local child advocacy center following a forensic assessment substantiating youth trauma exposure. Caregiver factors examined include caregiver demographics, trauma exposure, and mental health symptomology. Results from multivariate logistic regressions indicate that caregivers reporting more children residing in the household were significantly more likely to enroll youth in therapy (OR 2.27; 95 % CI 1.02, 5.03). Qualitative analyses further explicate that parents with personal trauma or therapy experiences expressed positive opinions regarding therapy services for youth, and were more likely to enroll in or complete services. Findings suggest that caregivers with personal traumatic experience and related symptomatology view therapy as important and are more committed to their child receiving therapy. Future research on service utilization is warranted and should explore offering parental psychoeducation or engagement strategies discussing therapy benefits to parents who have not experienced trauma and related mental health symptomatology.     

Functional connectivity abnormalities vary by amygdala subdivision and are associated with psychiatric symptoms in unilateral temporal epilepsy

The amygdala has been described as a structure affected by mesial temporal lobe epilepsy (MTLE). Indeed, it is suggested that amygdala abnormalities are related to the co-morbid depression and anxiety reported in MTLE. In this context, we investigated the relation between functional connectivity (FC) emerging from this structure in fMRI and depression and anxiety levels reported in MTLE patients. We focused on resting-state BOLD activity and evaluated whether FC differences emerge from each of three amygdala subdivisions (laterobasal, centromedial and superficial) in left and right MTLE groups, compared with healthy controls. Results revealed significant differences between patient groups and controls. Specifically, the left MTLE group showed abnormal FC for the left-sided seeds only. Furthermore, regardless of the seed, we observed more reliable differences between the right MTLE group and controls. Further analysis of these results revealed correlations between these impaired connectivities and psychiatric symptoms in both MTLE groups. Opposite relations, however, were highlighted: the more depressed or anxious the right MTLE patients, the closer their FC values approached controls; whereas the less anxious the left MTLE patients, the closer their FC values were normative. These results highlight how MTLE alter FC emerging from the limbic system. Overall, our data demonstrate that right TLE has a more maladaptive impact on emotion-related networks, in ways specific to the amygdala region, and the emotion symptom involved, than left TLE.     

Formation of Al3Ni2-type nanocrystalline τ 3 phases in the Al–Cu–Ni system by mechanical alloying

An elemental powder mixture of Al (70 at.%), Ni (15 at.%) and Cu (15 at.%) was milled in a high-energy ball mill for various times ranging from 10 to 100?h to form ternary intermetallic alloys. X-ray diffraction and transmission electron microscopy techniques were employed for characterization of the samples. The dissolution of the individual elements into an alloy led to the formation of a τ₃ vacancy-ordered phase after 100?h of milling. This phase was found to be quite stable against milling, and no other crystalline and amorphous phases could be detected. The powder after 100?h of milling was found to contain mostly τ₃ nanophases with partial ordering, and with crystallite sizes in the range 10–20?nm along with a lattice strain of ～0.675%. The milled powder, after annealing at 700°C for 20, 40 and 60?h, revealed the formation of a strain-free and ordered τ₃ phase with a crystallite size of 80?nm, indicating grain coarsening. It is interesting to note that the mechanical energy imparted during milling could not completely destroy the vacancy ordering in the τ₃ phase, unlike other stoichiometric Al–Cu–transition metal (TM) systems, where the disordered B2 (bcc) phase is commonly observed instead of any vacancy-ordered phases.     

Feasibility of Biological Sample Collection among a High-Risk Maternal Population for Child Maltreatment-Qualitative Pilot Findings

Little is known on the feasibility of biological sample collection among at-risk parents for child maltreatment participating in evidence-based parenting intervention studies evaluating behavioral outcomes. This study explored acceptability and feasibility of collecting biospecimen samples among 12 high-risk mothers. Data were taken from semi-structured baseline interviews among participants who provided salivary, hair and buccal swab samples for a pilot study examining biobehavioral stress responses to an evidence-based parenting program. Content analysis results suggest that while uncomfortable, biospecimen collection will not impede research participation. Providers should highlight connections between biology and behaviors to motivate parents and increase engagement in parenting programs.     

FUTURE ORIENTATION: A MEDIATOR IN TEMPORAL CODING

Influence of future orientation on temporal coding was investigated in two experimental studies. A three by two paradigm involving three conditions of list discrimination and two groups of subjects of high and low future orientation, was used. Story writing technique and list discrimination tasks were employed to assess future orientation and efficiency in using temporal codes, respectively. Results show that in experiment 1, when subjects had been forewarned about an impending memory test and hence there was a competition between these future demands and present demands of an orienting task, performance of high as compared to low future oriented subjects was better on list discrimination tasks; they utilized temporal codes more efficiently. This difference in performance between high and low future oriented groups of subjects was not evident in experiment 2 when there was no forewarning about an impending memory test. Temporal coding was better for different concept rather than same concept lists. It is argued that type of material, as well as perception of future utility of material, influence the amount of temporal coding for both groups of subjects, but dispositional future orientation also mediates the perception of the utility of a material in the future to affect its temporal coding.     

Early adversity in rural India impacts the brain networks underlying visual working memory

There is a growing need to understand the global impact of poverty on early brain and behavioural development, particularly with regard to key cognitive processes that emerge in early development. Although the impact of adversity on brain development can trap children in an intergenerational cycle of poverty, the massive potential for brain plasticity is also a source of hope: reliable, accessible, culturally agnostic methods to assess early brain development in low resource settings might be used to measure the impact of early adversity, identify infants for timely intervention and guide the development and monitor the effectiveness of early interventions. Visual working memory (VWM) is an early marker of cognitive capacity that has been assessed reliably in early infancy and is predictive of later academic achievement in Western countries. Here, we localized the functional brain networks that underlie VWM in early development in rural India using a portable neuroimaging system, and we assessed the impact of adversity on these brain networks. We recorded functional brain activity as young children aged 4–48 months performed a VWM task. Brain imaging results revealed localized activation in the frontal cortex, replicating findings from a Midwestern US sample. Critically, children from families with low maternal education and income showed weaker brain activity and poorer distractor suppression in canonical working memory areas in the left frontal cortex. Implications of this work are far‐reaching: it is now cost‐effective to localize functional brain networks in early development in low‐resource settings, paving the way for novel intervention and assessment methods.     

Perceived justice of available opportunities and self-esteem,collective esteem and social exclusion: A study of three religious groups in India

Groups have their own social realities which determine their perceptions of justice having impact on their well- being and consequent integration with the mainstream society. The objective of the present study was to understand variations in perceived justice in terms of opportunities existing in five different domains, i.e. social prestige, economic, educational, employment and political by the Hindu Majority (N = 100) and Muslim (N = 100) and Christian (N = 76) minorities in India. In addition, the study also aimed to understand the relationship of perceived justice with self-esteem, collective esteem and social exclusion. Male and female participants (N = 276) of the study were either of high or low caste, and were of employed or unemployed status from a north Indian city. The results indicate that justice perception is determined by religion and caste not by gender and employment status. The majority Hindus perceived significantly higher perceptions of justice than Christians and Muslims minorities on all four domains except education. For education the minority Muslim group had lower justice perceptions than Hindus and Christians who did not differ significantly. The three groups differed significantly in their ratings of social exclusion with maximum exclusion perceived by Christians and minimum by Hindus. Results have implications for development initiatives.
