Rrepresentations of trauma in infancy: Clinical and theoretical implications for the understanding of early memory

Understanding the nature of the infant's internal experience is a crucial prerequisite for delineating the developmental effects of an early trauma. In addition, to the extent that internal representations of a trauma can be traced over time, traumatic experiences present unique opportunities for the study of early memory. This article will describe case vignettes of children who experienced a trauma in the preverbal period and who evidenced forms of memory of their trauma at subsequent points in time. In conjunction with the clinical material, developmental research bearing on the types of early memories described will be discussed. The clinical data, reinforced by research findings, indicate that preverbal children, even in the first year of life, can establish and retain some form of internal representation of a traumatic event over significant periods of time. The specificity and enduring nature of the internal representations suggest that specific therapeutic interventions over and above general comforting will be required if an infant is to maximally recover from a trauma. The clinical findings have relevance for a number of issues currently under debate in the area of infant memory, including the role of reminders in memory retention, the nature of early memory systems, and the development of autobiographical memory. ©2002 Michigan Association for Infant Mental Health.     

Emergent Individuals

We explain the thesis that human mental states are ontologically emergent aspects of a fundamentally biological organism. We then explore the consequences of this thesis for the identity of a human person over time. As these consequences are not obviously independent of one's general ontology of objects and their properties, we consider four such accounts: transcendent universals, kind-Aristotelianism, immanent universals, and tropes. We suggest there are reasons for emergentists to favour the latter two accounts. We then argue that within such ontologies, emergentism about properties pushes one to the stronger claim that there are emergent individuals, though not individuals which are dual to person's bodies — substance emergentism, but not substance dualism.     

A linear growth curve analysis of inpatient treatment response by conduct‐disordered,ADHD, and comorbid preadolescents

Conduct disorder (CD) comorbid with attention deficit hyperactivity disorder (ADHD) is widely reputed to be treatment refractory, particularly when accompanied by aggression and early‐onset symptoms. Few studies, however, have assessed inpatient treatment response among early onset CD/ADHD children in detail. In the present investigation, behavioral and rating scale data were compared among CD (n=13), ADHD (n=20), and CD/ADHD (n=45) preadolescents during one‐month of multimodal inpatient treatment that included methylphenidate administration. As expected, linear growth curve analyses revealed that CD/ADHD children were the most symptomatic of the three groups. However, all groups benefited from hospitalization, with few differences in treatment responsiveness observed. Analyses of residualized symptoms suggested that methylphenidate administration was effective in curbing impulsive but not aggressive behaviors. Aggr.

Self‐Priming in Production: Evidence for a Hybrid Model of Syntactic Priming

Syntactic priming in language production is the increased likelihood of using a recently encountered syntactic structure. In this paper, we examine two theories of why speakers can be primed: error‐driven learning accounts (Bock, Dell, Chang, & Onishi, 2007; Chang, Dell, & Bock, 2006) and activation‐based accounts (Pickering & Branigan, 1999; Reitter, Keller, & Moore, 2011). Both theories predict that speakers should be primed by the syntactic choices of others, but only activation‐based accounts predict that speakers should be able to prime themselves. Here we test whether speakers can be primed by their own productions in three behavioral experiments and find evidence of structural persistence following both comprehension and speakers’ own productions. We also find that comprehension‐based priming effects are larger for rarer syntactic structures than for more common ones, which is most consistent with error‐driven accounts. Because neither error‐driven accounts nor activation‐based accounts fully explain the data, we propose a hybrid model.
