The Salience of Lower-Order, Localized Features in Highly Self-Similar Wallpaper Groups

Rick O. Gilmore & Anthony M. Norcia
There exists an abundance of visual symmetry within our environment. Yet research on human perception has almost exclusively been limited to studies of a single type of symmetry— two-fold reflection—leaving uncertainty about human perceptual sensitivity to the other types of symmetry as derived from the mathematics of Group Theory. Clarke et al. (2011) found that five of the seventeen wallpaper groups—P1, P3M1, P31M, P6, and P6M—have a high degree of self-similarity, as determined by the...

Understanding the development of motion processing by characterizing optic flow experienced by infants and their mothers

Rick O. Gilmore, Florian Raudies, John Franchak & Karen Adolph
Understanding the development of mature motion processing may require knowledge about the statistics of the visual input that infants are exposed to, how these change across development, and how they influence the maturation of motion-sensitive brain networks. Here we develop a set of techniques to study the optic flow experienced by infants and mothers during locomotion as a first step toward a broader analysis of the statistics of the natural visual environment during development.

Amnesia for object attributes: Failure to report attended information that had just reached conscious awareness

Brad Wyble
We intuitively believe that when we become consciously aware of a visual stimulus, we will be able to remember it for immediate report. The present study provides a series of striking demonstrations that are inconsistent with such an intuition. Four experiments showed that in certain conditions, participants cannot report an attribute (e.g. letter identity) of a stimulus, even when that attribute had been attended and reached a full state of conscious awareness just prior to...

Visual, manual, and postural coordination in the development of prehension

Karen Adolph
Using a dynamic reaching paradigm and recording technologies, the aim of this study is to describe the real-time cascade of postural, exploratory, and performatory movements that comprise typical manual actions, and to understand how these sequential and simultaneous components unfold over development. The study uses computerized video analysis, head-mounted eye tracking, high resolution motion tracking, and a motorized chair apparatus to study how infants coordinate body posture, eye movements and performatory reach-to-grasp movements under various...

Classroom discourse in elementary school engineering lessons

William Carlsen
We are studying discourse among elementary school teachers and children who are engaged in engineering lessons. Over 3000 videos are being filmed as part of an NSF-funded DRK12 efficacy study of Engineering is Elementary. The PI is Christine Cunningham, Museum of Science Boston.

Preschoolers' extension and export of information from realistic and fantastical stories (Study 2)

Deena Skolnick Weisberg
These studies investigate how children extend information within the context of fictional stories, how they export information from stories to reality, and whether these processes are affected by the story’s degree of realism. Preschool-aged children heard a story and judged whether events that happened at one point in that story could happen later in the story and could happen in real life.

Databrary sponsored workshops and events

Karen Adolph, Rick O. Gilmore, & Databrary Admin
Our mission is to promote sharing and reuse of video data. Most developmental scientists rely on video recordings to capture the complexity and richness of behavior. However, researchers rarely share video data, and this has impeded scientific progress. Enabling reuse of video data is essential to increasing openness, maximizing the efficiency of limited resources, and accelerating the pace of discovery in the developmental and learning sciences. We aim to provide tools that encourage good data...

Excerpt volume: Human quadrupeds, primate quadrupedalism, and Uner Tan Syndrome

Karen Adolph & Liza Shapiro
Since 2005, an extensive literature documents individuals from several families afflicted with “Uner Tan Syndrome (UTS),” a condition that in its most extreme form is characterized by cerebellar hypoplasia, loss of balance and coordination, impaired cognitive abilities, and habitual quadrupedal gait on hands and feet. Some researchers have interpreted habitual use of quadrupedalism by these individuals from an evolutionary perspective, suggesting that it represents an atavistic expression of our quadrupedal primate ancestry or “devolution.” In...

Biological Motions

Bennett I. Bertenthal
The structure of the human form is quickly and unequivocably recognized from 10 to 13 points of light moving as if attached to the major joints and head of a person walking Recent psychophysical and computational models of this process suggest that these displays are organized by low-level processing constraints that delimit the pair-wise connections of the point lights In the current research, these low-level constraints were rendered uninformative by a masking paradigm The results...

Magnet imitation task demonstration

Rachel Barr
This is an excerpt of children doing the magnet imitation task on both a touchscreen and on a magnet board. The task allows researchers to probe how children learn to transfer information between 2D and 3D surfaces to examine memory representations. In practice the task has implications for puzzle play and also for learning from touchscreens and television during early childhood.

Teach to reach: The effects of active vs. passive reaching experiences on action and perception

Amy Needham
Reaching is an important and early emerging motor skill that allows infants to interact with the physical and social world. However, few studies have considered how reaching experiences shape infants’ own motor development and their perception of actions performed by others. In the current study, two groups of infants received daily parent guided play sessions over a 2-weeks training period. Using ‘‘Sticky Mittens”, one group was enabled to independently pick up objects whereas the other...
