In neuropsychology literature (cases of right-hemisphere-damaged patients):

"Investigators have described significant impairments in the abilities to express emotions (Ross & Mesulam, 1979) and to detect the emotional aspects of other individuals' expressions and communication (Cicone, Wapner, & Gardner, 1980; Tucker, Watson, & Heilman, 1977); the right hemisphere also seems to be dominant for emotional appropriateness (Gardner, 1975; Geschwind, 1976). In addition, atypical senses of humor have been reported for these patients (Gardner, Ling, Flamm, & Silverman, 1975). There is also considerable documentation of anasagnosia following right hemisphere injury: Patients with such injury are far more likely than left-hemisphere-injured patients to deny their illness, to ignore paralyzed limbs, to claim that they are fine, or to confabulate a spurious cause of their illness, as did Justice Douglas (Weinstein & Kahn, 1955)." (Gardner et al. 1983)[1]

Patients have difficulty in summarizing stories, extracting morals (tend to use exact phrases instead of creating more abstract descriptions), comprehending jokes, detecting abnormalities (invent to normalize incongruent details without noticing bizarre sentences or notice them but quick to normalize them) (Gardner et al. 1983)[1].
