Comprehension of humor in primary agenesis of the corpus callosum

Brown, Warren S., Paul, Lynn K., Symington, Melissa, Dietrich, Rosalind·2005·Neuropsychologia

Abstract

Individuals with agenesis of the corpus callosum (ACC) can, in some cases, perform normally on standardized intelligence tests. Nevertheless, recent studies suggest that individuals with ACC and normal IQ scores have deficits in domains of fluid and social intelligence. Anecdotal reports from families suggest diminished appreciation of the subtleties of social interactions, and deficits in the comprehension of jokes and stories. In this research, both the cartoon and narrative joke subtests of a humor test (developed by Brownell et al. [Brownell, H., Michel, D., Powelson, J., & Gardner, H. (1983). Surprise but not coherence: sensitivity to verbal humor in right-hemisphere patients. Brain and language, 18(1), 20-27] and Bihrle et al. [Bihrle, A. M., Brownell, H. H., Powelson, J. A., & Gardner, H. (1986). Comprehension of humorous and non-humorous materials by left and right brain-damaged patients. Brain and Cognition, 5(4), 399-411]) were given to 16 adults with complete ACC (all with IQs>80) and 31 controls of similar age and IQ. Individuals with ACC performed worse than controls on the narrative joke subtest (p<.025) when VIQ was controlled. However, on the cartoon subtest the two groups were not significantly different. Covarying age, forms of IQ, narrative memory, set-switching, and literal language comprehension did not substantially alter the group difference. However, covarying comprehension of nonliteral language and proverbs eliminated the difference, suggesting a common origin for the comprehension of jokes, nonliteral language, and proverbs, most likely related to capacity for understanding second-order meanings.

  • Patients with agenesis of corpus callosum show difficulties in language and social communication, and decreased volume of the corpus callosum has been found in ASD.

    “Patients with agenesis of corpus callosum show difficulties in language and social communication [45, 276, 357], and decreased volume of the corpus callosum has been found in ASD (see meta-analysis in [114]).”

  • The results are consistent with evidence from investigations of individuals with agenesis of the corpus callosum.

    “Results reported here are consistent with evidence from investigations examining individuals with agenesis of the CC, pointing to the role that this structure plays in complex brain functions.”

  • Several cognitive and social deficits observed in autism have also been described in individuals with agenesis of the corpus callosum.

    “Several cognitive and social deficits observed in autism have also been described in individuals with agenesis of the CC, although not all individuals with these deficits meet full DSM-IV-TR criteria for autistic disorder.”

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.
