     Animal studies of cannabinoids reveal widely varying behavioral effects, but several appear consistently. One is a hyperreflexive response to specific stimuli accompanying the overall sedative effects.

   • 2013 -, Curtis W. Dewey, A Practical Guide to Canine and Feline Neurology, →ISBN, page 389:

     The patellar reflex is typically normal or may appear hyperreflexive.

   • 2015, Thomas P. Colville, Joanna M. Bassert, Clinical Anatomy and Physiology for Veterinary Technicians, →ISBN, page 250:

     Not only are the reflex arcs functioning in the hind limbs despite the damage to the spinal cord at L1 to L2, but the reflex responses are hyperreflexive.

2. Tending toward abnormally high levels of introspection.
   • 2000, Dan Zahavi, Exploring the Self, →ISBN, page 171:

     But Artaud describes certain strange transformations of facial awareness that one might imagine occurring under conditions of prolonged withdrawal and hyperreflexive contemplation — conditions in which the normally implicit and inner is extruded into a state of quasi-externality.

   • 2003, Tilo Kircher, Anthony David, The Self in Neuroscience and Psychiatry, →ISBN, page 350:

     Secondly, however, as Sass (1998, 2000) suggests, metarepresentation and a certain degree of overmonitoring of experience can be generated in hyperreflexive experience, when processes that are ordinarily tacit (processes that I normally do not have to monitor explicitly or consciously) come to the subject's attention.

   • 2004, Shaun Gallagher, Stephen Watson, Philippe Brun, Ipseity and alterity: Interdisciplinary Approaches to Intersubjectivity, →ISBN, page 87:

     The passage describes a lived face that, under conditions of hyperreflexive awareness and diminished self-affection, seems to be turned inside out, flattened and extruded until it becomes a kind of fluid mask — a fragile lived membrane of squirming sensitivity and kaleidoscopic pattern that seems to lift off from his head to float independently in the air.

   • 2013, KWM Fulford, Martin Davies, Richard Gipps, The Oxford Handbook of Philosophy and Psychiatry, →ISBN, page v:

     This hyperreflexive “turning backward” toward the self is incompatible with more spontaneous, world-directed forms of activity.

3. (mathematics) Having a bounded local distance of operators in a nested algebra or reflexive subspace
   • 2016, Chafiq Benhida, Kamila Kliś-Garlicka, Marek Ptak, “Skew-symmetric operators and reflexivity”, in arXiv‎^[1]:

     In contrast to the subspaces of all $C$-symmetric operators, we show that the subspaces of all skew-C symmetric operators are reflexive and even hyperreflexive with the constant $\kappa (\mathbb {C} ^{s})\leqslant 3$..
