Dynamic decision-making is a complex process that relies on our ability to generate, evaluate and implement a variety of strategies. Understanding how people navigate this process is a difficult problem that requires a wide range of methodologies. This study details a combination of behavioral experiments, computational modeling, and neuroimaging that...
Humans are prodigious learners. One of our most powerful learning tools is the ability to detect and transfer relational similarities between items and events, despite their perceptual differences. Previous research has found that the roots of this ability extend into infancy. As early as three months of age, infants can...
Language is a hallmark of human cognition—a rich and flexible method of representing the world around us. As such, language provides an invaluable resource to human infants: a way of gaining insight into the representations that guide adult cognition. In this dissertation, I explore how language influences infants’ cognition as...
Many theories of categorization have included an intuitive role for our ability to detect and judge similarity. Yet, this important role of similarity processing has been disputed. This research adopts a model of similarity processing through structure mapping (Gentner, 1983) to explore its role in similarity processing and categorization. Relational...
Episodic memory provides a means by which we are able to reflect on the past, make decisions about the future, and form a learned identity. Even subtle changes to our memory can have a detrimental impact on our daily lives. Memory declines as we age, and clinically salient impairment is...
Emotion perception is multisensory and involves decoding and integrating input from both visual and auditory modalities. This dissertation investigates the influence of cultural and linguistic experience on multisensory perception of emotion. Experiment 1 examines the effect of cultural background on modality bias (i.e., the amount of influence a modality exerts...
People evidence behaviors that engender hope for future behavior change, but also evidence this hope when there is no reason to believe that any behavior change will occur. For example, prior research suggests that temporal factors make people susceptible to change their minds over time, and a confluence of cognitive...
Young children can sometimes acquire new vocabulary words—even property terms—through indirect learning (e.g. Carey & Bartlett, 1978). We explore two factors that contribute to this ability—perceptual alignment and linguistic contrast. We propose that spontaneous comparison processes lead children to notice key commonalities and differences that facilitate indirect property word learning....
Rhythmic fluctuations of electrical activity in the brain provide insights into the proposed mechanism by which we encode experiences and then maintain, forget, modify, and retrieve them. Yet there is still much to learn about how neural oscillations relate to memory function. The purpose of this research is to discover...
