Antipredator defensive behaviors in a visible burrow system

Blanchard, Robert J., Blanchard, D. Caroline·1989·Journal of comparative psychology

Abstract

Analyzed defensive behaviors in a seminatural setting through videorecordings of groups of 4 male and 4 female rats. Before cat exposure dominant males showed more offensive behavior, eating, drinking, and use of the open area than subordinates. Presentation of a cat in the open area produced changes in four subpatterns of defense over a 24-hr period: withdrawal; immobility and movement constraint; risk assessment; and suppression of nondefensive behaviors. All Ss showed pronounced and consistent changes in each of these patterns, but dominant males alone showed increased risk assessment-related corner runs. These results provide an extensive description of rat defensive behaviors in a seminatural and relatively unstructured situation and suggest that the anxiety process is initially associated with withdrawal and movement arrest, giving way to a crucial and long-lasting risk-assessment stage that provides information leading to either further defensiveness or a return to nondefensive behaviors. This analysis suggests new models for the study of anxiety.

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?

  • Male rats confronted with threatening stimuli such as a predator or predator odor exhibit similar orienting responses, described as risk assessment or vigilance behavior.

    “Male rats confronted with threatening stimuli such as a predator or predator odor exhibit similar orienting responses (74), which have been described as risk assessment or vigilance behavior (24).”
  • Play fighting in rats is most common during the early juvenile period and then gradually decreases, while serious fighting is generally rare even in naturalistic settings.

    “Firstly, play fighting is most common during the early juvenile period (and then it gradually decreases 102,117 ), while serious fighting is generally rare even in naturalistic settings. 118”

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.
