Snarc Effect, A Negative Number Processing

The Mechanism of Digital Processing and Representation of Space is a hot-discussed cognitive psychology research in recent years. In the domain of spatial representation of the positive number, the researchers are revolving the mental number line supposition, make good use of the distance effect, the size effect as well as the SNARC effect experiment foundation of Representation of Space, for several dozens years have obtained the massive consistent research results. But in domain of the negative number space representation, The Ontogenetic Hypothesis thinks in mental number line the representation both include the positive number part and negative number part, the digital space mental representation similar to number axis, the negative number representation in left, positive number representation in right; But Phylogenetic Hypothesis thought that the mental number line only includes the positive number mental representation, do not include negative mental representation, to the negative number, only does not carry on the spatial representation. To the negative number numerical part, the negative number according to its absolute value size from left from the right representation in the psychological number word and line. Because basic theory's mutual argument as well as the system research lack, the research model not unified and so on questions, creates is not comprehensive to the negative number processing spatial representation understanding. In view of these questions, this research plans to use in the SNARC effect research the fast size classification, as well as the positive number, the negative number present alternately the model studies the negative number the spatial attribute and the attribute direction.This research basis existing rationale, mainly designed two experiments to confirm or to attest to falsity of Ontogenetic Hypothesis with Phylogenetic Hypothesis.As soon as the experiment uses the classics fast size classification the research model, the use material is two negative integers, discusses the pure negative number section by the representation direction. Tests two uses the experiment model which the classics the fast size classification and the negative number positive number present alternately unify, integrates the entire digital section the negative number, overall discusses the negative number in the entire digital section representation.The main conclusions of this research are as follows:The negative number spatial representation conforms to the forecast of Ontogenetic Hypothesis. The number representation already includes the positive number in mental number line but also the negative number, take 0 as the center, the mental digit wire gauge resembles the mental number spool thread, the digit according to its actual size representation in the mental number line, negative number representation in mental number line left side, positive number in representation in mental number line right side.
