About

Why do some children seem more drawn to media than others, and what shapes those differences?

This question sits at the center of my research. I am a Ph.D. candidate in Human Development at Virginia Tech, where I study children's media use as a window into individual differences in temperament, development, and family environments.

Much of my work focuses on early childhood. I am particularly interested in how child temperament shapes patterns of media engagement and vulnerability to problematic media use. At the same time, I examine environmental influences, especially how parental factors help shape children's media experiences. In my work, I consider multiple dimensions of media use, including media interactivity. Although my work centers primarily on early childhood, I also conduct research on media use during adolescence.

Beyond media, I examine how temperament relates to children’s developmental and learning outcomes, including social competence and learning-related behaviors.

I approach these questions using longitudinal and person-centered methods, structural equation modeling, meta-analytic methods, and machine learning to better capture complexity in developmental processes.

I am currently a Graduate Research Assistant in the Cognitive Developmental Science (CoDeS) Lab at Virginia Tech and expect to complete my Ph.D. in May 2027.

False memories: Subjective and objective responses to an "accented" voice assistant
Walker, A., Quesenberry, E., Morris, K., Gürdal, M. S., Yu, S., Choi, K., Katz, B., & Jeon, M.
Phonetica · Advance online publication · 2026
The default accent of voice assistants tends to be a standard variety of a language, and commentary around creating voice assistants (VAs) suggests that more regionally marked dialects are avoided for their more marked social associations and their (assumed) reduced intelligibility. In our study, participants "user-tested" two VAs, one with a Southern US English accent, and one with a Mainstream US English accent. Northern US participants evaluated the Southern VA more negatively and commented that she was harder to understand. On the other hand, Southern participants had mixed valence affective reactions to the Southern VA and International participants demonstrated no strong social associations with either accent, and both groups rarely mentioned intelligibility of either VA. Additionally, in a listening game (a short version of the DRM false memory paradigm), there were no significant effects of VA accent on real or false memories for any of the three participant groups. Our results add to work suggesting that while linguistic variation can lead to challenges in communication, intelligibility is often invoked too easily as a reason for exclusion. The potential benefits of and problems around expanding variation in the voices of voice assistants are also discussed.
Suppress or reappraise? Differential roles of maternal emotion regulation strategies in mothers' and toddlers' interactive and non-interactive screen media use

Although parental emotional challenges and emotion-based media motivations are linked to screen media use patterns in families of toddlers, little work has examined parental emotion regulation strategies in relation to parents' and toddlers' screen media use. Because these strategies are modifiable components of how parents manage emotional demands, investigating them is an important next step for understanding factors associated with family media use and informing media guidance. The present study examined associations between maternal emotion regulation strategies (expressive suppression and cognitive reappraisal) and both maternal and toddlers' screen media use, distinguishing between non-interactive and interactive forms given their differing implications for toddler development. Mothers of toddlers (18–36 months, N = 296) reported their emotion regulation strategies and both their own and their toddlers' screen media use through an online survey. Data were analyzed using multivariable regression models, with additional analyses testing indirect associations. Results indicated that higher levels of maternal expressive suppression were associated with greater maternal non-interactive screen media use and with both types of toddlers' screen media use. Higher levels of maternal non-interactive screen media use were linked to greater non-interactive and interactive screen media use among toddlers, whereas maternal interactive screen media use was not related to either form of toddlers' screen media use. No significant associations were found between maternal cognitive reappraisal and maternal or toddlers' screen media use. These findings highlight the differential roles of parental emotion regulation strategies in maternal and toddlers' screen media use, particularly the distinct role of expressive suppression relative to cognitive reappraisal, and offer implications for supporting healthy family media practices.
Self-regulation profiles and social competence in early childhood: A person-centered approach
Gürdal, M. S., & Acar, İ. H.
Early Education and Development, 37(2), 371–387 · 2026
Research Findings: Social competence in early childhood serves as a foundation for later developmental and academic outcomes. Although self-regulation is widely recognized as a key contributor to social competence, previous studies have primarily employed variable-centered approaches to examine the relation between self-regulation and social competence. In the current study, we adopted a person-centered approach to construct self-regulation profiles and examined the relation between these profiles and social competence. A total of 607 children (Mage = 56.89 months, 54% male) participated in the study, in which self-regulation was measured using performance-based assessments and social competence was assessed through teacher-reported measures. Latent profile analysis identified three self-regulation profiles: "optimal self-regulators" (71%), "moderate self-regulators" (12%), and "challenged self-regulators" (17%). The results indicated that children in the optimal self-regulators profile exhibited higher levels of social competence compared to those in the moderate and challenged self-regulator profiles. Practice or Policy: Findings highlight the need for tailoring self-regulation interventions to children's distinct self-regulation profiles, as a one-size-fits-all approach may be less effective in promoting social competence.
Foreign language anxiety and language learning beliefs: A comparative study of six language learner groups
Gürdal, M. S., & Acar, İ. H.
The Journal of Quality in Education, 14(23), 44–60 · 2024
The present study investigates the relationship between foreign language anxiety and beliefs towards foreign language learning, considering personal and social-environmental factors that may influence language learners' beliefs. The participants consisted of 431 college students (M = 19.99, SD = 4.57 years) enrolled in language preparatory classes in Türkiye, focusing on Arabic, Chinese, English, German, Russian, and Spanish. The students provided self-reports on their levels of foreign language anxiety, including speech anxiety, failure anxiety, and low self-confidence, as well as their beliefs towards foreign language learning. The results of hierarchical regression analysis revealed that failure anxiety was positively associated with students' beliefs towards foreign language learning, indicating that higher levels of failure anxiety were linked to less favorable beliefs. On the other hand, low self-confidence was negatively associated with beliefs towards foreign language learning, suggesting that lower levels of self-confidence were associated with more negative beliefs. Speech anxiety, however, speech anxiety showed no significant association with students' beliefs towards foreign language learning. Furthermore, it was observed that foreign language anxiety and beliefs towards foreign language learning differed based on the specific foreign language being learned. These findings underscore the importance of examining foreign language anxiety in relation to beliefs towards foreign language learning, particularly within diverse language learner populations.
