Recent studies have established that even preverbal infants can monitor and regulate their mental states, raising the question of the variables involved in this early metacognitive development. Here, the metacognition of fifty-five 18-month-old (27 females; mostly White; data collection: 2023) was assessed using an eye-tracking paradigm designed…

Sleep is instrumental in the formation of long-lasting memories, including social evaluations and social knowledge. The modification of social evaluations holds profound significance for understanding and shaping societal dynamics. Here, we investigated how sleep could contribute to updating the social evaluation of a person generally perceived as…

Mandarin is a tone language that is spoken by billions of people in the world. Despite huge demand, there is a lack of assessment and treatment tools targeting Mandarin speakers with communication disorders. To better understand the speech profile of Mandarin speakers with communication disorders, this dissertation first examined contrastive…

There is growing consensus that selection history strongly guides spatial attention and is distinct from current goals and physical salience. Here, we focused on target-location probability cueing: when the target is more likely to appear in one region, search performance gradually improves for targets appearing in that region. Probability cueing…

When memories are reactivated during sleep, they are potentially transformed and strengthened. However, disturbed sleep may make this process ineffective. In a prior study, memories formed shortly before sleep were weakened by auditory stimulation when that stimulation provoked memory reactivation while also disrupting sleep -- a procedure known…

Social learning is a fundamental mechanism for efficiently transferring and coordinating norms, skills, and sophisticated cultural information to individuals. However, the psychological mechanisms underlying social learning remain unclear. To investigate this, we recruited adult participants (N = 103), who observed a model's performance in a…

The improvements in attention by mindfulness training have been proved. However, the effects of mindfulness training on attention to emotional stimuli were mixed. We employed a randomized, controlled design to investigate the effects of mindfulness training on attention to emotional expressions, and investigated whether baseline levels of…

Attention allows us to focus on relevant information while ignoring distractions. Effective suppression of distracting information is crucial for efficient visual search. Recent studies have developed two paradigms to investigate attentional suppression: cued-suppression which is based on top-down control, and learned-suppression which is based on…

Motivational (i.e., appetitive or aversive) cues can bias value-based decisions by affecting either direction and intensity of instrumental actions. Despite several findings describing important interindividual differences in these biases, whether biological sex can also play a role is still up to debate. By comparing females and males in both…

This dissertation examines the associations between pragmatic meaning categories in English and specific realizations of prosodic prominence. It has been well-established that in Mainstream American English (MAE), prominence is often used to convey contrast. A more limited set of studies suggests that prosodic prominence may also be capable of…

This paper undertakes a thorough evaluation of ChatGPT's code generation capabilities, contrasting them with those of human programmers from both educational and software engineering standpoints. The emphasis is placed on elucidating its importance in these intertwined domains. To facilitate a robust analysis, we curated a novel dataset comprising…

This research comprises two studies investigating the impact of mood and cognitive stimulation on creativity, with a focus on the role of task type. The first study focused on idea generation, whereas the second explored slogan generation, revealing differing outcomes for distinct tasks. Positive and negative moods were induced through memory…

Background: While highlighting is one of the most common strategies to enhance reading comprehension, little is known about how highlighting behavior and its relationship with performance varies across cultures. Our purpose was to examine whether the use and the success of highlighting prevalence, quantity, and task relevance vary internationally.…

Metacognitive reasoning is central to decision-making. For every decision, we can also judge our trust in that decision, or our level of "confidence." The mechanisms and representations underlying reasoning about confidence remain debated. We test whether children rely on "processing fluency" to infer their own confidence: do…

In healthcare, effective communication in complex situations such as end of life conversations is critical for delivering high quality care. Whether residents learn from communication training with actors depends on whether they are able to select appropriate information or 'predictive cues' from that learning situation that accurately reflect…
