Language production and memory researchers both study the long term effects of semantic retrieval. Both fields have routinely observed the same semantic interference phenomenon, in which generation from memory impairs subsequent access to semantically related representations. However, to date there has been very little communication across these literatures and our understanding of conceptual-lexical retrieval is fragmented across fields. In this dissertation I propose that the language production and memory literatures are ostensibly studying different aspects of the same semantic interference phenomenon and that an integration of the separate but complementary accounts of conceptual-lexical retrieval is long overdue. Thus the goal of this dissertation was to lay the groundwork for further integrative efforts. I developed a verbal integrated incremental learning account of conceptual-lexical access to serve as a blueprint for future model development and tested a subset of the resulting hypotheses across three empirical components. In Component 1, Retrieval-Induced Semantic Interference, I developed a modified version of the retrieval practice paradigm, which would serve as the primary methodology for the dissertation. I shed light on how interference unfolds over time by implementing an internally structured continuous naming design in each phase, and the effect of past generative activity was assessed in the final phase by comparing related picture naming latencies to unrelated experimental controls. The results confirmed that cumulative interference occurs during a standard memory manipulation (category-stem cued retrieval) and that this interference carries forward to a subsequent phase of continuous picture naming. These findings thus use a fine-grained temporal analysis to highlight the common basis of adaptive learning processes and show that related retrieval affects subsequent lexical access, regardless of the specific task. Component 2, Adaptive Learning After Semantic Interference: Does Interference Promote Enhanced Relearning?, explored the memory claim of enhanced relearning (Storm et al., 2008; Hulbert & Anderson, 2015; Ritvo et al., 2019) in which relearning after semantic interference results in heightened accessibility compared to both initial levels and unpunished controls. I examined the unfolding of learning and relearning over generation, relearning, and assessment phases and found evidence for restoration but not enhancement of accessibility for past competitors. This finding calls into question the generality of enhanced relearning and suggests that it may chiefly apply to novel learning contexts rather than acting on preexisting conceptual-lexical networks. Component 3, Durability and Locus of Retrieval-Induced Semantic Interference, sought to investigate the durability of retrieval-induced semantic interference and the respective contributions of conceptual versus conceptual-lexical adaptive learning. Experiments 3A and 3B used a continuous picture naming procedure in two phases separated by a short or overnight retention interval to assess the durability of semantic interference as well as the possible role of sleep-based consolidation. In contrast to the prior two components, I only found retrieval-induced semantic interference after nocturnal sleep, and this interference was only manifest as increased production errors. Experiments 3C and 3D explored the origin and locus of retrieval-induced semantic interference. These experiments introduced a novel variation of a pre-lexical picture matching task to elicit conceptual-level as distinct from conceptual-lexical adaptive learning. To assess the impact of this learning, the final assessment phase involved either generative picture naming or a continuation of picture matching. In both experiments, the initial picture matching phase produced cumulative facilitation over each related generation. In Experiment 3C, the following picture naming phase produced cumulative interference, but there was no effect of the previous phase. Experiment 3D did not find significant cumulative processes nor cross-phase facilitation in the final matching assessment phase. The results of this component indicate that more work is needed to ascertain the durability of interference and that interference may only manifest when lexical retrieval is a required stage of processing. The dissertation concludes with an update of the blueprint for an integrated memory and language production account of conceptual-lexical retrieval. Together, the present work shows that assuming a combined memory-language approach to the study of retrieval-induced semantic interference is not only illuminating, but necessary to fully characterize the dynamics of the conceptual-lexical interface.
