Putting the elephant back in the herd: elephant relative quantity judgments match those of other species

Perdue, Bonnie M., Talbot, Catherine F., Stone, Adam M., Beran, Michael J.·2012·Animal Cognition

Abstract

The ability to discriminate between quantities has been observed in many species. Typically, when an animal is given a choice between two sets of food, accurate performance (i.e., choosing the larger amount) decreases as the ratio between two quantities increases. A recent study reported that elephants did not exhibit ratio effects, suggesting that elephants may process quantitative information in a qualitatively different way from all other nonhuman species that have been tested (Irie-Sugimoto et al. in Anim Cogn 12:193-199, 2009). However, the results of this study were confounded by several methodological issues. We tested two African elephants (Loxodonta africana) to more thoroughly investigate relative quantity judgment in this species. In contrast to the previous study, we found evidence of ratio effects for visible and nonvisible sequentially presented sets of food. Thus, elephants appear to represent and compare quantities in much the same way as other species, including humans when they are prevented from counting. Performance supports an accumulator model in which quantities are represented as analog magnitudes. Furthermore, we found no effect of absolute magnitude on performance, providing support against an object-file model explanation of quantity judgment.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Both Asian and African savanna elephants can discriminate between different quantities of food using both or either visual and/or auditory cues.

    “both Asian and African savanna elephants can discriminate between different quantities of food using both or either visual and/or auditory cues (when baits were dropped into a container; Irie-Sugimoto et al., 2009; Perdue et al., 2012; Snyder et al., 2021).”
  • Other studies on elephant quantity discrimination have found different results, which were consistent with the accumulator model.

    “However, other studies on elephant quantity discrimination have found different results, which were consistent with the accumulator model (Perdue et al., 2012; Plotnik et al., 2019; Snyder et al., 2021).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
