The radical exemplar model resonates with work on perceptual classification and categorization highlighting the role of exemplars in memory representations. Further development of the model requires acknowledgment of both the fleeting and fragile nature of perceptual representations and the gist-based, good-enough quality of long-term memory…

Westergaard (2021) presents an updated account of the Linguistic Proximity Model and the micro-cue approach to the parser as an acquisition device. The property-by-property view of transfer inherent in this approach contrasts with other influential models that assume that third language (L3) acquisition involves the creation of a full copy of only…

This provocative article raises many important issues that need to be addressed and in so doing will advance the fields of second language (L2) and third language (L3) acquisition in several important ways. Fundamental questions concerning multilingual development persist especially with respect to the role of Universal Grammar in this language…

Purpose: This paper aims to provide an overview of the Organization Learning and Learning Organization concepts obtaining the perspectives of Professor Mary M. Crossan and presents an evolution of her immense contribution to the field over the past two decades. Design/methodology/approach: A conversation with thought-leader, Professor Mary M.…

Exemplar-based learning requires: (1) a segmentation procedure for identifying the units of past experiences that a present experience can be compared to, and (2) a similarity function for comparing these past experiences to the present experience. This article argues that for a learner to learn a language these two mechanisms will require…

In her keynote article advocating the Linguistic Proximity Model for third language (L3) acquisition, Westergaard (2021) presents several arguments against 'copying and restructuring' in nonnative language acquisition, mechanisms central to Schwartz and Sprouse's (1996) Full Transfer/Full Access model of second language (L2) acquisition. In this…

This article reviews two aspects of human learning: (1) people draw inferences that appear to rely on hierarchical conceptual representations; (2) some categories are much easier to learn than others given the same number of exemplars, and some categories remain difficult despite extensive training. Both of these results are difficult to reconcile…

This personal reflective essay explores a group Dissertation in Practice (DiP) model and process used in a localized Doctor of Education program. It describes and recommends this team-based DiP approach as an innovation that prepares practitioners to tackle complex problems of practice by focusing on a process centered around group dynamics that…

Ambridge argues persuasively for the importance in language learning of a rich database of input exemplars. However, a fuller account must also consider the importance of on-line and developmental competition between rote exemplar-based storage and emergent patterns that can optimize retrieval. [For Ben Ambridge's "Against Stored…

Ambridge argues that there is widespread agreement among child language researchers that learners store linguistic abstractions. In this commentary the authors first argue that this assumption is incorrect; anti-representationalist/exemplar views are pervasive in theories of child language. Next, the authors outline what has been learned from this…

In this commentary on this issue's focus article by Baird et al., Pellegrino focuses first on the fundamental nature of educational assessment and its connection to theories, models, and data on learning. He then discusses the contemporary views of learning in the form of learning progressions as they relate to assessment development. In the third…

This commentary begins by summarizing the five contributions to this special issue and briefly recapping the background to the topic of student learning in higher education. Narrative and systematic reviews are compared, and the relative value of different bibliographic databases in the context of systematic reviews is assessed. The importance of…

Massive open online courses (MOOCs) are online courses aimed at global unlimited participation, originally conceptualised to carry no fee and offer no formal accreditation to the students (McAuley et al. 2010). Although their pedagogies vary, the most popular MOOC providers (e.g., Coursera, FutureLearn and EdX) are turning towards what Rodriguez…

Humans are sensitive to the properties of individual items, and exemplar models are useful for capturing this sensitivity. I am a proponent of an extension of exemplar-based architectures that I briefly describe. However, exemplar models are very shallow architectures in which it is necessary to stipulate a set of primitive elements that make up…

Ambridge argues that the existence of exemplar models for individual phenomena (words, inflection rules, etc.) suggests the feasibility of a unified, exemplars-everywhere model that eschews abstraction. The argument would be strengthened by a description of such a model. However, none is provided. I show that any attempt to do so would immediately…
