The aim of this article is to reinterpret the results obtained from the research analyzing the role played by spatial frequencies in face perception. Two main working lines have been explored in this body of research: (a) the critical bandwidth of spatial frequencies that allows face recognition to take place (the masking approach) and (b) the role played by different spatial frequencies while ...

In this paper I compare the performance of a standard genetic algorithm versus a microgenetic algorithm for matching a randomly-generated seismic trace to a reference trace with the same frequency spectrum. A micro genetic algorithm evolves a very small population that must be restarted whenever the population loses its genetic diversity. I show that the micro-genetic algorithm is more efficien...

Nurmoja, Eamets, Härma, and Bachmann (2012) revealed that strongly pixelated pictures of faces still provide relevant cues for reliably assessing the apparent (i.e., subjectively perceived) traits of the portrayed. The present article responds to the paper by developing the outline of a framework for future research to reveal certain steps in processing complex visual stimuli. This framework co...

A polynomial function supervising fuzzy sliding mode control (PSFaSMC), which embedded with skyhook surface method, is proposed for the ride comfort of a vehicle semiactive suspension. The multi-objective microgenetic algorithm (MOlGA) has been utilized to determine the PSFaSMC controller’s parameter alignment in a training process with three ride comfort objectives for the vehicle semi-active ...

Genetic algorithms (GAs) are considered very useful tools for the optimal allocation of capacitor banks in distribution systems. Nonetheless a high computational effort can be requested mainly in large scale systems. In the paper three GA-based methods for the optimal sizing and siting of capacitors in unbalanced multiconverter distribution networks are applied and compared to obtain a good sol...

A critical aspect of perception-action coupling is the ability to modify ongoing actions in accordance with variations in the environment. Infants' ability to modify their gait patterns to walk down shallow and steep slopes was examined at three nested time scales. Across sessions, a microgenetic training design showed rapid improvements after the first session in infants receiving concentrated...

Explaining new ideas to oneself can promote transfer, but how and when such self-explanation is effective is unclear. This study evaluated whether self-explanation leads to lasting improvements in transfer success and whether it is more effective in combination with direct instruction or invention. Third- through fifth-grade children (ages 8-11; n=85) learned about mathematical equivalence unde...

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...
