    Heuristics and Biases in Mental Arithmetic: Revisiting and Reversing Operational Momentum.Samuel Shaki, Michal Pinhas & Martin H. Fischer - 2018 - Thinking and Reasoning 24 (2):138-156.
    Mental arithmetic is characterised by a tendency to overestimate addition and to underestimate subtraction results: the operational momentum effect. Here, motivated by contentious explanations of this effect, we developed and tested an arithmetic heuristics and biases model that predicts reverse OM due to cognitive anchoring effects. Participants produced bi-directional lines with lengths corresponding to the results of arithmetic problems. In two experiments, we found regular OM with zero problems but reverse OM with non-zero problems. In a third experiment, we tested (...)

  4. The Approximate Number System Represents Rational Numbers: The Special Case of an Empty Set.Michal Pinhas, Rut Zaks-Ohayon & Joseph Tzelgov - 2021 - Behavioral and Brain Sciences 44.
    We agree with Clarke and Beck that the approximate number system represents rational numbers, and we demonstrate our support by highlighting the case of the empty set – the non-symbolic manifestation of zero. It is particularly interesting because of its perceptual and semantic uniqueness, and its exploration reveals fundamental new insights about how numerical information is represented.

    In Search of Non-Abstract Representation of Numbers: Maybe on the Right Track, but Still Not There.Joseph Tzelgov & Michal Pinhas - 2009 - Behavioral and Brain Sciences 32 (3-4):353 - 354.
    We agree that the default numerical representation is best accessed by probing automatic processing. The locus of this representation is apparently at the horizontal intraparietal sulcus (HIPS), the convergence zone of magnitude information. The parietal lobes are the right place to look for non-abstract representation of magnitude, yet the proof for that is still to be found.
