Metaphors for grad school

The broad nature of Cognitive Science means that the research in our department is incredibly diverse. (more)



Miller, L.E, Longo, M.R., Saygin, A.P. (2014). Tool morphology constrains the effects of tool use on body representations. Journal of Experimental Psychology: Human Perception and Performance. In press.
What factors constrain whether tool use modulates the user's body representations? To date, studies on representational plasticity following tool use have primarily focused on the act of using the tool. Here, we investigated whether the tool's morphology also serves to constrain plasticity. In 2 experiments, we varied whether the tool was morphologically similar to a target body part (Experiment 1, hand; Experiment 2, arm). Participants judged the tactile distance between pairs of points applied to their tool-using target body surface and forehead (control surface) before and after tool use. We applied touch in 2 orientations, allowing us to quantify how tool use modulates the representation's shape. Significant representational plasticity in hand shape (increase in width, decrease in length) was found when the tool was morphologically similar to a hand (Experiment 1A), but not when the tool was arm-shaped (Experiment 1B). Conversely, significant representational plasticity was found on the arm when the tool was arm-shaped (Experiment 2B), but not when hand-shaped (Experiment 2A). Taken together, our results indicate that morphological similarity between the tool and the effector constrains tool-induced representational plasticity. The embodiment of tools may thus depend on a match-to-template process between tool morphology and representation of the body.

recent technologies have made it cost-effective to collect diverse types of genome-wide data. computational methods are needed to combine these data to create a comprehensive view of a given disease or a biological process. similarity network fusion (snF) solves this problem by constructing networks of samples (e.g., patients) for each available data type and then efficiently fusing these into one network that represents the full spectrum of underlying data. For example, to create a comprehensive view of a disease given a cohort of patients, snF computes and fuses patient similarity networks obtained from each of their data types separately, taking advantage of the complementarity in the data. We used snF to combine mrnA expression, dnA methylation and micrornA (mirnA) expression data for five cancer data sets. snF substantially outperforms single data type analysis and established integrative approaches when identifying cancer subtypes and is effective for predicting survival.

Featured Classes
Fall 2014:
  • COGS9: Introduction to Data Science
    Concepts of data and its role in science will be introduced, as well as the ideas behind data-mining, text-mining, machine learning, and graph theory and how scientists and companies are leveraging those methods to uncover new insights into human cognition.
  • COGS160: Cognitive Ethnomusicology
    Music is ubiquitously present in human culture. As much as it is ubiquitous, music is diverse in both form and usage. From sacred ritual to war, music is a component of many human activities. Free from the semantic necessities of language, music is constrained only by the aesthetics of those making it. Ethnomusicology seeks to understand music in its cultural context--how and why people make the specific types of music they do. Cognitive ethnomusicology takes a broad approach to the study of musical culture, perception, and processing. The course will explore fundamental components of musical behavior, such as synchronized rhythm or the use of visual symbols to enhance recall of musical ideas, while also exploring specific genres or styles of music that have unique characteristics, such as the timbre-melodies of Tuvan vocal music or the complex rhythmic patterns of Carnatic Mrdangam playing.
  • COGS219: Prog. for Behavioral Sci.
    Students learn how to use Matlab and the Psychophysics toolbox for experimental research in cognitive science, neuroscience, psychology, linguistics and related fields… Topics include stimulus presentation, response collection, analyzing and displaying data. Programming is an applied skill; like playing an instrument or a sport, it needs to be practiced. COGS219 provides information, support, motivation, structure, and "coaching”. Students acquire skills they can apply at graduate school and beyond, feel more confident in their programming and research abilities, and develop code that can be adapted for research projects. For cognitive science students, 219 counts as a methods course; with professor approval, it can count as behavioral or computational issues course.
  • COGS160: Interaction Design Research
    Prepares students to conduct original HCI research by reading and discussing seminal and cutting-edge research papers. Topics include design, social software, input techniques, mobile, and ubiquitous computing. Student pairs perform a quarter-long mini research project that leverages campus research efforts. TuTh 3:30pm-4:50pm in CSE 2154. Prerequisites: (Cogs14a or CSE20) and (an A- or higher in Cogs120 or Cogs102C). Please contact Thanh Maxwell at tmaxwell@ucsd.edu for departmental approval.

  • Motion simulation and the subjective direction of time
    It is often suggested that people make predictions about the world by simulating how the world might unfold, but considerably less is known about how people make retrodictions: inferring the past state of the world based on the present. The current research investigates the shared and differing cognitive processes underlying ...

  • 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 ...

A single model explains both visual and auditory precortical coding
Precortical neural systems encode information collected by the senses, but the driving principles of the encoding used have remained a subject of debate. We present a model of retinal coding that is based on three constraints: information preservation, minimization of the neural wiring, and response equalization. The resulting novel version of sparse principal components analysis successfully captures a number of known characteristics of the retinal coding system, such as center-surround ...
