The Declarative/Procedural Model of Lexicon and Grammar

Our use of language depends upon two capacities: a mental lexicon of memorized words and a mental grammar of rules that underlie the sequential and hierarchical composition of lexical forms into predictably structured larger words, phrases, and sentences. The declarative/procedural model posits that the lexicon/grammar distinction in language is tied to the distinction between two well-studied brain memory systems. On this view, the memorization and use of at least simple words (those with noncompositional, that is, arbitrary form-meaning pairings) depends upon an associative memory of distributed representations that is subserved by temporal-lobe circuits previously implicated in the learning and use of fact and event knowledge. This declarative memory system appears to be specialized for learning arbitrarily related information (i.e., for associative binding). In contrast, the acquisition and use of grammatical rules that underlie symbol manipulation is subserved by frontal/basal-ganglia circuits previously implicated in the implicit (nonconscious) learning and expression of motor and cognitive skills and habits (e.g., from simple motor acts to skilled game playing). This procedural system may be specialized for computing sequences. This novel view of lexicon and grammar offers an alternative to the two main competing theoretical frameworks. It shares the perspective of traditional dual-mechanism theories in positing that the mental lexicon and a symbol-manipulating mental grammar are subserved by distinct computational components that may be linked to distinct brain structures. However, it diverges from these theories where they assume components dedicated to each of the two language capacities (that is, domain-specific) and in their common assumption that lexical memory is a rote list of items. Conversely, while it shares with single-mechanism theories the perspective that the two capacities are subserved by domain-independent computational mechanisms, it diverges from them where they link both capacities to a single associative memory system with broad anatomic distribution. The declarative/procedural model, but neither traditional dual- nor single-mechanism models, predicts double dissociations between lexicon and grammar, with associations among associative memory properties, memorized words and facts, and temporal-lobe structures, and among symbol-manipulation properties, grammatical rule products, motor skills, and frontal/basal-ganglia structures. In order to contrast lexicon and grammar while holding other factors constant, we have focused our investigations of the declarative/procedural model on morphologically complex word forms. Morphological transformations that are (largely) unproductive (e.g., in go—went, solemn—solemnity) are hypothesized to depend upon declarative memory. These have been contrasted with morphological transformations that are fully productive (e.g., in walk—walked, happy—happiness), whose computation is posited to be solely dependent upon grammatical rules subserved by the procedural system. Here evidence is presented from studies that use a range of psycholinguistic and neurolinguistic approaches with children and adults. It is argued that converging evidence from these studies supports the declarative/procedural model of lexicon and grammar.     

Mathematical Abilities in Elementary School Children with Autism Spectrum Disorder

Although clinical practitioners often express concerns about the mathematical functioning of children with autism spectrum disorder (ASD), the field of mathematics remains a relatively unexplored topic in individuals with ASD. Moreover, research findings are fragmentary and hold inconclusive results. The present study aimed to examine whether grade 1 (aged 6–7 years) to 4 (aged 9–10 years) elementary school children with ASD scored significantly different from age‐adequate norms on mathematics. To this end, a multi‐componential approach of mathematics was used. Four domains of mathematics were assessed in 121 children with ASD: procedural calculation, number fact retrieval, word/language problems, and time‐related competences. All children attended general education classrooms, following the standard curriculum, and were coached by integrated educational services. Children with ASD showed a strength in word/language problems in second and fourth grade. There was evidence of a weakness for procedural calculation in first grade and for time‐related competences in first and third grade. In all other cases, average scores were shown. As such, results revealed a profile of strengths, average abilities, and weaknesses in mathematics and highlighted the importance of focusing on different domains of mathematics. Because a high variability in mathematical performance could be observed, we recommend an individual assessment when considering the mathematical trajectory of children with ASD.

Salesperson knowledge distinctions and sales performance

Although it is conceptually and practically posited that salesperson knowledge has a direct relationship to performance, empirical research concerning this topic has been limited. In a free elicitation study of 150 multi-line insurance agents, the authors demonstrate that higher performing sales personnel have more elaborate, contingent and context-specific procedural knowledge than that of less effective agents. Moreover, higher performing sales personnel's contingent knowledge is shown to be more relevant to the sales call and more adaptive or responsive to the specific contingency than lower performers. In addition, higher performers have more intermediary and indirect goals prior to initially contacting a prospect. These results fuel a call for further research concerning the procedural knowledge roots underlying sales performance, as well as the practical exigencies involved in developing, managing and retaining the knowledge resource of the sales force as a firm-level asset.     

小学儿童程序公平认知及其归因取向的发展

为了探讨小学儿童的程序公平认知以及不同程序信息下程序公平认知归因取向的发展特点,研究采用自编的程序公平认知情境故事材料,对150名小学1、3、5年级儿童进行测查。结果表明：小学儿童的程序公平认知能力随年级增长而提高,在有投票权且同等和有投票权但不等下的程序公平认知得分显著高于在无投票权下,在消极结果信息下的程序公平认知得分显著高于在积极结果信息下,且年级、程序信息、结果信息两两之间和三者之间均存在显著交互作用。随年级增长,小学儿童的程序公平认知归因在结果取向和权威取向上不断减少,在过程取向上不断增多,在能力取向上则是上升到3年级之后又逐渐减少。研究说明小学儿童的程序公平认知能力随年龄增长而发展,并受程序信息和结果信息的影响;小学儿童的程序公平认知归因随年龄增长越来越倾向于过程取向。     

Making conscious the unconscious in order to modify unconscious processing: Some mechanisms of therapeutic change1

This paper examines some of the mechanisms through which interpretation aimed primarily at increasing conscious awareness can nonetheless produce unconscious changes, the latter being deemed the basic aim of psychoanalysis. The concept of valency or motivational weight of the interpretation is proposed to assess which forces of the various motivational systems the interpretation mobilizes (hetero/self‐preservation, sensual/sexual, attachment, narcissistic, psychobiological regulation etc.), on which of the above‐mentioned systems interpretation relies, and which would oppose therapeutic intervention and why. Certain conditions are also analyzed that could explain the so‐called ‘change through the analytic relationship’, pointing out that, despite the major differences between this form of change and change through interpretation, both of them would share certain mechanisms. This conclusion leads to the need to qualify the idea that interpretation would be exclusively aimed at declarative memory, with no effects upon procedural memory. The paper examines the potential consequences for therapeutic techniques derived from recent fi ndings in neuroscience on so‐called labile state memory, and proposes the coupling of experiences as one of the analytical instruments used for therapeutic change. A clinical vignette is included to illustrate some of the theoretical and technical aspects considered.     

Longitudinal study of declarative and procedural memory in primary school‐aged children

This study examined the development of declarative and procedural memory longitudinally in primary school‐aged children. At present, although there is a general consensus that age‐related improvements during this period can be found for declarative memory, there are conflicting data on the developmental trajectory of the procedural memory system. At Time 1 children aged around 5½ years were presented with measures of declarative and procedural memory. The tasks were then administered 12 months later. Performance on the declarative memory task was found to improve at a faster rate in comparison to the procedural memory task. The findings of the study support the view that multiple memory systems reach functional maturity at different points in development.     

Dimensions of Pediatric Procedural Distress: Children's Anxiety and Pain During Immunizations

The purpose of this study was to isolate and compare children's procedural anxiety and pain. The study was conducted in a school-based pediatric health clinic with 39 fourth graders receiving 3 injection vaccinations over a 6-month period. Child and nurse ratings and an observational scale assessed anxiety and pain. Results suggest that anxiety and pain are highly correlated, however self-report and an observational measure discriminate between these constructs. Self-report and observational measurement indicated more pediatric pain than anxiety, whereas nurse reports did not indicate differences between children's pain and anxiety.     

Explaining the procedural justice–perceived legitimacy relationship: Relying on relational concern or instrumental concern?

People can extract relational information (i.e., relational concern) as well as instrumental information (i.e., instrumental concern) from decision‐making procedures. Thus, both instrumental and relational concerns are assumed to influence the procedural justice–perceived legitimacy relationship. Drawing from social exchange theory, the different kinds of concerns may lead to form different exchange relationships (social exchange relationship vs. economic relationship), which can be indicated by two forms of trust (affect‐based trust vs. cognition‐based trust). We built a model of trust mediation in which procedural justice predicted affect‐based and cognition‐based trust. Further, we also tested the hypothesis that high (compared with low) group identification individuals are more likely to rely on relational concern to construct procedural justice and judge legitimacy of authority, because they use procedural fairness information to infer the quality of their relationships with the authority. The results of an experiment (Study 1) demonstrated that both affect‐based trust and cognition‐based trust mediated the procedural justice–perceived legitimacy relationship. Moreover, a field study (Study 2) showed that affect‐based trust mediated the relationship between procedural justice and perceived legitimacy primarily among individuals with high group identification whereas cognition‐based trust mediated this relationship primarily among those with low group identification.     

The relationship between phonological processing and arithmetic in children with learning disabilities

Phonological processing skills have not only been shown to be important for reading skills, but also for arithmetic skills. Specifically, previous research in typically developing children has suggested that phonological processing skills may be more closely related to arithmetic problems that are solved through fact retrieval (e.g., remembering the solution from memory) than procedural computation (e.g., counting). However, the relationship between phonological processing and arithmetic in children with learning disabilities (LDs) has not been investigated. Yet, understanding these relationships in children with LDs is especially important because it can help elucidate the cognitive underpinnings of math difficulties, explain why reading and math disabilities frequently co-occur, and provide information on which cognitive skills to target for interventions. In 63 children with LDs, we examined the relationship between different phonological processing skills (phonemic awareness, phonological memory, and rapid serial naming) and arithmetic. We distinguished between arithmetic problems that tend to be solved with fact retrieval versus procedural computation to determine whether phonological processing skills are differentially related to these two arithmetic processes. We found that phonemic awareness, but not phonological memory or rapid serial naming, was related to arithmetic fact retrieval. We also found no association between any phonological processing skills and procedural computation. These results converge with prior research in typically developing children and suggest that phonemic awareness is also related to arithmetic fact retrieval in children with LD. These results raise the possibility that phonemic awareness training might improve both reading and arithmetic fact retrieval skills.

Research Highlights

• Relationships between phonological processing and various arithmetic skills were investigated in children with learning disabilities (LDs) for the first time.
• We found phonemic awareness was related to arithmetic involving fact retrieval, but not to arithmetic involving procedural computation in LDs.
• The results suggest that phonemic awareness is not only important to skilled reading, but also to some aspects of arithmetic.
• These results raise the question of whether intervention in phonemic awareness might improve arithmetic fact retrieval skills.
