This study explores possible links between ontogenetic and microgenetic change (Werner, 1948, 1957) in the perception of stimuli with multiple levels of structure. Visual search for targets defined by local versus global structure was examined in observers aged 6, 8, 10, and 22 years. Perceptual access to each level of structure was varied by using pattern elements of same (easy) or opposite co...

An approach in modeling collaborative and metacognitive data is presented in this paper. The proposed scheme, namely Collaboration/ Metacognition–Adaptive Network-based Fuzzy Inference System (C/M-ANFIS), uses neurofuzzy structure to adaptively infer on the relation between the above data in a meaningful way. More specifically, the collaborative and metacognitive data refer to the participant’s...

This essay traces the history of an activity designed to promote the intellectual and social development of elementary-age schoolchildren during the afterschool hours. Following in the footsteps of Urie Bronfenbrenner, I highlight his argument that just as all human development occurs in contexts of varying levels of inclusiveness and mutual interchange, human development occurs at intersecting...

In this article I discuss an excerpt from a group discussion between five 15year-old boys who, in the presence of an adult moderator, engaged in the act of ‘slut bashing’ while telling a minimal story about an incident of female promiscuity. The analysis proceeds microanalytically in a three-step procedure that details the positions taken by the young participants during the interaction. First,...

The developmental trajectory of perceptual organization in humans is unclear. This study investigated perceptual grouping abilities across a wide age range (8-30 years) using a classic compound letter global/local (GL) task and a more fine-grained microgenetic prime paradigm (MPP) with both few- and many-element hierarchical displays. In the GL task, contrary to adults, both children and adoles...

The marked contrast between the scientific consensus on global warming and public beliefs indicates a need to research how high schoolers, as future citizens, engage with make meaning from news articles such topics. In case of socioscientific issues (SSIs) warming, students’ acquisition knowledge is mediated by their epistemic understandings nature science (NOS) use informal reasoning in evalua...

Abstract The objective of this case study was to identify the role finger gestures in learning mathematics informally during play, especially sociocultural settings. A mathematical activity involving addition qualitatively analyzed at a Japanese preschool. We explored how process subjectification and objectification contributed preschool preschoolers’ changed mathematics. utilized Radford’s the...

In this article, we present the blueprint for a new class of methods—inter-modal pre-constructive methods—uniting value moving across modalities understanding (poetry, drawing, music, etc.) in scheme microgenetic construction affective fields. For purpose, historical roots methods were reviewed, and two empirical demonstrations are provided. demonstration, possibility exploring hyper-generalize...
