TITLE: Infant learning from multi-sensory sources: a blessing or curse?
Chia-huei Tseng （The University of Hong Kong）
Abstract
One of the most fascinating abilities in human beings is our ability to learn from examples, and then generalize the principle to new contexts. This ability is seemingly ready at early infancy, although its limitation, development, and the exact mechanism are still poorly understood.
In this seminar, I will center around these questions: for infants, is multi-sensory learning always better? How is the high-level learning generality modulated by low-level perceptual information? I will also discuss our results and their implications in our understanding of infants’ language acquisition and abstract concept formation.

TITLE: The structure of object recognition from shape processing: the
comparison of perceptual decisions between detection and
categorization
Kohsuke Taniguchi（Research Center for Psychological Science, Doshisha University）
Abstract
Object recognition is involved in perceptual decisions: detection and
categorization at various levels. According to traditional theory,
object recognition involves hierarchal structure: first, detection can
be decided, and then categorization is processed. However,
Grill-Spector and Kanwisher (2005) suggested that the processing of
basic-level categorization is almost the same as in that of detection
and subordinate-level categorization needs further processing. This
suggestion shows that the structure of object recognition remains open
question. In the current research, focusing on the shape information
in object, we investigate relationships between perceptual decisions:
detection, basic-level categorization and superordinate-level
categorization, to specify the structure of object recognition. In
study 1, the correlations between the perceptual decisions and shape
features of line-drawing objects, such as the number of edge, degree
of circularity, curvature singularities and subjective estimation,
were investigated. In study 2, the difference of temporal dynamics in
reaction time was compared between perceptual decisions. These study
showed that each perceptual decision involves different processing.
Therefore, we suggest the original model involving clustering
structure. The processing of object recognition applies to cluster of
perceptual decisions involving the component of process, such as shape
information, concept of objects and so on. We consider that this model
can explain the processing of object recognition more comprehensively
and specifically than previous models.
同志社大学赤ちゃん学研究センターは、今まで様々な研究領域で行われてきたものを融合させ、ヒトの起点である胎児期から乳児期にかけての行動、認知、身体の発達に関する基礎的な原理を明らかにすることによって「ヒト」から「人」へとかわる発達のメカニズムを解明することを目的として設立されました。
2016年度から文部科学省により共同利用・共同研究拠点として認可され、その事業の一つとして定期的にセミナーを開催することにいたしました。このセミナーは、①人の発達にかかわる様々な研究者を結びつけ、②子育てをする養育者の方々、保育・幼稚園の関係者、看護・療育の関係者などに最新の赤ちゃん学の知見を得ていただき現場で利活用いただくことを目指しています。上記関係者の他、ご興味をお持ちの方を含め、多くの方のご参加をお待ちしています。
