Creel, S. C. (2014). Tipping the scales: Auditory cue weighting changes over development. Journal of Experimental Psychology: Human Perception and Performance, 40(3), 1146–1160. doi:10.1037/a0036057
How does auditory processing change over development? This study assessed preschoolers’ and adults’ sensitivity to pitch contour, pitch height, and timbre in an association-memory paradigm, with both explicit (overt recognition) and implicit measures (visual fixations to melody-linked objects). In the first 2 experiments, child and adult participants associated each of 2 melodies with a cartoon picture, and recognition was tested. Experiment 1 pitted pitch contour cues against pitch height cues, and Experiment 2 pitted contour cues against timbre cues. Although adults were sensitive to multiple cues, children responded predominantly based on pitch height and timbre, with little sensitivity to pitch contour. In Experiment 3, however, children detected changes to all 3 cues well above chance levels. Results overall suggest that contour differences, although readily perceptible, are less memorable to children than to adults. Gradual perceptual learning over development may increase the memorability of pitch contour.
Borovsky, A., & Creel, S. C. (2014). Children and adults integrate talker and verb information in online processing. Developmental Psychology, 50(5), 1600–13. doi:10.1037/a0035591
Children seem able to efficiently interpret a variety of linguistic cues during speech comprehension, yet have difficulty interpreting sources of nonlinguistic and paralinguistic information that accompany speech. The current study asked whether (paralinguistic) voice-activated role knowledge is rapidly interpreted in coordination with a linguistic cue (a sentential action) during speech comprehension in an eye-tracked sentence comprehension task with children (ages 3–10 years) and college-aged adults. Participants were initially familiarized with 2 talkers who identified their respective roles (e.g., PRINCESS and PIRATE) before hearing a previously introduced talker name an action and object (“I want to hold the sword,” in the pirate’s voice). As the sentence was spoken, eye movements were recorded to 4 objects that varied in relationship to the sentential talker and action (target: SWORD, talker-related: SHIP, action-related: WAND, and unrelated: CARRIAGE). The task was to select the named image. Even young child listeners rapidly combined inferences about talker identity with the action, allowing them to fixate on the target before it was mentioned, although there were developmental and vocabulary differences on this task. Results suggest that children, like adults, store real-world knowledge of a talker’s role and actively use this information to interpret speech.

  • Language Development and Remediation in Children
    We are evaluating two interventions for dyslexia that involve training the temporal dynamics of the visual system (magnocellular pathway) and the auditory system, and whether the two interventions together have super-additive effects. As a Research Assistant, you would be traveling to one or two of five participating local elementary schools ...

  • Brain Mechanisms Meditating Attentional Sets and Navigational Decisions
    Movement through the environment demands constant change in how we take in information (our attentional set) and how we use that information to make decisions. The Nitz laboratory studies this dynamic process at its core, by directly examining the neural substrates of attention and spatial cognition through multiple single neuron ...

  • Brain Development and Cognitive Function in Children
    The Center for Human Development (CHD) at UCSD conducts research projects focusing on factors that influence developing minds and personalities. For example, researchers at the CHD ask questions like how and why do we become individuals? What role is played by our experiences? By our genes? How does developing behavior ...

  • Space, Time, and Gesture
    While it is clear that people around the world talk and think about time in terms of spatial concepts, many questions remain regarding the link between spatial and temporal concepts. The Embodied Cognition lab is interested in understanding cognition from the perspective of the embodied mind, investigating how the peculiarities ...

  • Body Movements: Dots, Humans, Robots
    The perception and comprehension of others’ actions and body movements is ubiquitous and important. Our lab carries out a range of behavioral, neuroimaging, and neuropsychological experiments on how people perceive others' body movements. In many experiments, we use body movements depicted by point-lights (like this: We are also exploring ...
