What are the true functional underpinnings of perception, emotion, consciousness, and subconscious processes remains an unsolved question (Alivisatos et al., 2012). For example, it seems somewhat mysterious how one and the same structure of neural circuits—the human brain—sometimes allows conscious experience and sometimes does not allow it.

The Heritability of All-or-None Traits: Viability of Poultry.

N E of the fundamental steps in any analysis of the inheritance of quan0 titative characters is the partitioning of the total phenotypic variance of the trait under study into it; genetic and environmental portions. The various techniques for this purpose for characters showing continuous or graded types of variation are well known (see WHATLEY 1942). They are based on methods of variance and c...

All-or-None Subprocesses in the Learning of Complex Sequence+

This paper reports a study designed to investigate whether the all-or-none conception of the learning process can be extended to a learning task more complex than conditioning or simple verbal association. The experimental task is to learn numerical sequences by anticipating each new member of the sequences. Although the obtained sequence learning appears very complex, it proves to be analyzabl...
