About

Hello, I’m Katarina Antolovic, and I am a Ph.D. Candidate at the Graduate Center, CUNY in the Department of Speech-Language-Hearing Sciences.

Our mental lexicon is characterized by a complex network of relationships between words. My work focuses on how different types of semantic relationships (i.e., semantic associations, categorically-related words, etc.) affect word retrieval.

My research uses an interdisciplinary framework drawn from psycholinguistics and cognitive psychology to examine sources of interference and facilitation during word retrieval in aging and bilingualism. Specifically, I am interested in how domain-general interference control abilities modulate the degree of semantic and cross-linguistic interference encountered during word retrieval.

Interference control reportedly declines with aging, potentially leaving older adults more susceptible to linguistic interference. My works aim to define the types of linguistic relationships that generate interference in the hopes that we can leverage this knowledge in aphasia treatment and in detecting signs of pathological aging (e.g., mild cognitive impairment).

My previous work has investigated how individual differences in linguistic experiences, such as informal language interpretation, influence language processing and representation. I have also been involved in a collaborative effort to improve methods of quantifying cross-linguistic overlap among cognates. I received my B.A. in Linguistics and B.S. in Communication Sciences & Disorders from the University of Texas at Austin.

Neural indices of semantic network activation in aging

My dissertation work seeks to better understand how cognitive aging impacts the way speakers use input to guide speech production. Cognitive aging introduces changes in how individuals avoid interference during task performance, making the study of aging an interesting vehicle for understanding phenomena such as speech production.

In doing so, I move away from rigid models of the mental lexicon that assume a hierarchical structure to lexical-semantic representation. Alternatively, I adopt the framework of a dynamic lexicon that shifts with speaker and contextual input, drawing from a model known as the Swinging Lexical Network Hypothesis (e.g., Abdel Rahman & Melinger, 2019).

To assess how cognitive aging impacts lexical selection and word production, I use a mixed-methods approach that combines behavioral measures and neural responses (via EEG).

Aging, interference and semantic associations

This study employed a psycholinguistic and cognitive framework to investigate sources of interference during word retrieval for older adults. We used a modified picture-word interference paradigm, adapted for online data collection, to explore the types of semantic relationships that can delay lexical selection. This work also examined whether older adults are indeed more susceptible to linguistic interference than younger adults, as proposed by models from cognitive psychology. Finally, I explored how a person’s ability to manage linguistic interference is linked to their ability to manage non-linguistic forms of interference.
