Comprehension of humorous and nonhumorous materials by left and right brain-damaged patients

Right hemisphere-damaged (RHD) and left hemisphere-damaged (LHD) aphasic patients were tested on a nonverbal cartoon completion task that included a humorous (Joke) and a nonhumorous (Story) condition. In both conditions, RHD patients performed worse than LHD patients. More importantly, the qualitative difference between the errors produced by the two groups suggests that right and left hemisphere brain damage impairs different components of narrative ability. RHD patients showed a preserved sensitivity to the surprise element of humor, and a diminished ability to establish coherence. Conversely, LHD patients, when they erred, showed an impaired sensitivity to the surprise element of humor, and a preserved ability to establish coherence by integrating content across parts of a narrative. These results suggest that the observed humor comprehension deficits of RHD patients result specifically from right hemisphere disease and not from brain damage irrespective of locus. The performances of the RHD and LHD patients groups together support a separation of narrative ability from the traditional aspects of language ability typically disrupted in aphasia.     

Inference deficits in right brain-damaged patients

The inferential reasoning ability of right hemisphere-damaged (RHD) patients was tested by presenting pairs of sentences which were to be treated as single, integrated units. The two sentences treated together made one interpretation likely (a correct inference); one of the sentences in isolation encouraged a different interpretation (an incorrect inference). The position of the misleading sentence was systematically varied. Results showed that, in contrast to normal controls, RHD patients have more trouble answering inference questions, especially those concerning incorrect inferences, than answering questions about the factual content of the passages. Also, RHD patients made significantly more errors when the misleading information was contained in the first rather than in the second sentence; this finding indicates that these patients have difficulty revising previously acquired knowledge in light of new information. These results suggest the impairment of several components of normal discourse processing subsequent to right hemisphere brain damage.     

Fundamental frequency encoding of linguistic and emotional prosody by right hemisphere-damaged speakers.

To illuminate the nature of the right hemisphere's involvement in expressive prosodic functions, a story completion task was administered to matched groups of right hemisphere-damaged (RHD) and nonneurological control subjects. Utterances which simultaneously specified three prosodic distinctions (emphatic stress, sentence modality, emotional tone) were elicited from each subject group and then subjected to acoustic analysis to examine various fundamental frequency (F(0)) attributes of the stimuli. Results indicated that RHD speakers tended to produce F(0) patterns that resembled normal productions in overall shape, but with significantly less F(0) variation. The RHD patients were also less reliable than normal speakers at transmitting emphasis or emotional contrasts when judged from the listener's perspective. Examination of the results across a wide variety of stimulus types pointed to a deficit in successfully implementing continuous aspects of F(0) patterns following right hemisphere insult.     

Neural substrates of linguistic prosody: evidence from syntactic disambiguation in the productions of brain-damaged patients

The present investigation focussed on the neural substrates underlying linguistic distinctions that are signalled by prosodic cues. A production experiment was conducted to examine the ability of left- (LHD) and right- (RHD) hemisphere-damaged patients and normal controls to use temporal and fundamental frequency cues to disambiguate sentences which include one or more Intonational Phrase level prosodic boundaries. Acoustic analyses of subjects' productions of three sentence types-parentheticals, appositives, and tags-showed that LHD speakers, compared to RHD and normal controls, exhibited impairments in the control of temporal parameters signalling phrase boundaries, including inconsistent patterns of pre-boundary lengthening and longer-than-normal pause durations in non-boundary positions. Somewhat surprisingly, a perception test presented to a group of normal native listeners showed listeners experienced greatest difficulty in identifying the presence or absence of boundaries in the productions of the RHD speakers. The findings support a cue lateralization hypothesis in which prosodic domain plays an important role.     

Memory and encoding of spoken discourse following right hemisphere damage: evidence from the Auditory Moving Window (AMW) technique

We investigated the hypotheses that impaired discourse processing following right hemisphere damage is mediated by task difficulty and is associated with deficits in discourse encoding. Spoken discourse passages differing in contextual predictability were presented to right hemisphere-damaged (RHD) patients and to non-brain-damaged (NBD) controls for subsequent recall using the Auditory Moving Window paradigm. To manipulate processing difficulty, speech segments were of normal or accelerated speech rates. The recall results showed that RHD adults recalled less than NBD controls overall and failed to recall major idea units better than minor idea units for high predictability passages presented at accelerated speech rates. Both RHD patients and NBD controls failed to recall major idea units better than minor idea units for low predictability passages, regardless of speech rate. The encoding results showed that RHD adults were both slower overall and differentially slower than NBD controls when listening to accelerated passage segments. Taken together, the encoding and recall results are consistent with the view that extracting passage gist under difficult listening conditions is especially vulnerable for patients with right hemisphere strokes.     

Characterizing sentence intonation in a right hemisphere-damaged population

Current production studies present a mixed view of right hemisphere-damaged (RHD) patients' ability to produce normal sentence intonation. The present study characterized the sentence intonation of RHD patients, focusing on a greater number of acoustic parameters than past works, and relying on more naturally elicited speech samples through use of a story completion task. Eight RHD speakers and seven nonneurological control subjects produced declarative and imperative sentences as well as yes-no and wh-questions. Slope of F0 change, linearity of pitch contour, and variance of F0 points were calculated for each utterance as a whole, as well as for the preterminal and the terminal contour separately. RHD contours were less linear and flatter in F0 decline than normal controls for the declarative sentences. The patients' yes-no questions also differed from normal productions, displaying smaller F0 dispersion around a mean F0. Preterminal range values were more restricted for patients' utterances of yes-no questions, while terminal properties between groups differed for three of the four sentence types examined. The present results suggest some disturbance in the patients' ability to manipulate fundamental frequency across sentential domains. These data are discussed in terms of current theories of a general dysprosody in RHD patients.     

Associations and dissociations of transitive and intransitive gestures in left and right hemisphere stroke patients

The study investigated performance on pantomime and imitation of transitive and intransitive gestures in 80 stroke patients, 42 with left (LHD) and 38 with right (RHD) hemisphere damage. Patients were also categorized in two groups based on the time that has elapsed between their stroke and the apraxia assessment: acute–subacute (n = 42) and chronic (n = 38). In addition, patterns of performance in apraxia were examined. We expected that acute–subacute patients would be more impaired than chronic patients and that LHD patients would be more impaired than RHD patients, relative to controls. The hemisphere prediction was confirmed, replicating previous findings. The frequency of apraxia was also higher in all LHD time post-stroke groups. The most common impairment after LHD was impairment in both pantomime and imitation in both transitive and intransitive gestures. Selective deficits in imitation were more frequent after RHD for transitive gestures but for intransitive gestures they were more frequent after LHD. Patients were more impaired on imitation than pantomime, relative to controls. In addition, after looking at both gesture types concurrently, we have described cases of patients who suffered deficits in pantomime of intransitive gestures with preserved performance on transitive gestures. Such cases show that the right hemisphere may be in some cases critical for the successful pantomime of intransitive gestures and the neural networks subserving them may be distinct. Chronic patients were also less impaired than acute–subacute patients, even though the difference did not reach significance. A longitudinal study is needed to examine the recovery patterns in both LHD and RHD patients.     

Leader Humor Extends beyond Work: how and when Followers Have Better Family Lives

Although the consequences of leader humor on subordinates have been well documented, the important issues of how and when leader humor affects employees’ attitudes or behaviors beyond the workplace have received limited attention. We integrate the humor literature with spillover-crossover theory to address the gap regarding the implications of leader humor in the nonwork domain. By performing an experiment and two field studies involving employee-spouse dyads, we consistently find 1) a positive association between leader humor and followers’ job satisfaction, 2) a spillover effect of followers’ job satisfaction on subordinates’ work-to-family enrichment (WFE) and a crossover effect of subordinates’ WFE on their spouses’ marital satisfaction, 3) serial mediating effects of followers’ job satisfaction and WFE on the leader humor-spouses’ marital satisfaction link, and 4) a stronger positive indirect effect of leader humor on spouse’ marital satisfaction via followers’ job satisfaction and WFE when followers’ perceived organizational interpersonal harmony is low. We discuss the theoretical implications of these findings and suggest practical implications for developing leader humor to enhance employee well-being.

     

Expressed emotion in depressed patients and their partners.

This study was designed to assess the expressed emotion (EE) status in the spouses of depressed patients and the patients themselves, to relate the EE status to the severity of depression as measured by the Beck Depression Inventory (BDI), and to compare the prevalence of high EE between the target and control group. Seventeen depressed patients and their spouses, and 20 control couples participated in the study. The Five-Minute Speech Sample was used to assess the EE status. High EE was significantly more common in spouses of depressed patients and the patients themselves than in controls. There was a significant relationship between the EE status of the patients and their spouses. High EE in the patient and in the spouse corresponded significantly with a high BDI score of the patient. These findings underline the importance that in EE research the patients' EE status as well as their present mental health state must also be taken into account.     

Sexual Attitudes of Males and Females as Predictors of Interpersonal Attraction and Marital Compatibility1

Two investigations examine the effect of similarity of sexual attitudes on (a) attraction to a stranger and (b) marital sexual satisfaction. In an experiment using undergraduates, manipulation of subject-stranger similarity in general affective orientation to sexuality affected attraction and other evaluative dependent variables. In the second investigation, married couples revealed sexual attitudes and sexual satisfaction. Husbands and wives were similar (r= 0.58, p < 0.001) in their affective orientations to sexuality. Discrepancy between the partners’ scores predicted sexual dissatisfaction in both partners. In addition, the wife's affective orientation to sexuality predicted more indices of sexual satisfaction and adjustment in both the wife and the husband than did the husband's affective orientation to sexuality. Finally, spouses with a positive affective orientation to sexuality were more accurate when judging their partner's sexual enjoyment, compared to spouses with a negative orientation. The findings have implications for the effects of similarity of attitudes on interpersonal attraction and on relationship quality.     

Autobiographical memory: influence of right hemisphere damage on emotionality and specificity

This study investigated the ability of right hemisphere damaged (RHD) patients to recall autobiographical material in response to emotional versus nonemotional cues. A modified Crovitz paradigm was used in which patients were asked to recall a specific episode from their own life that related to a cue word. These episodes were rated for emotionality and specificity by independent raters. Patients also rated the emotionality of their own episodes. Independent raters judged the reports of the RHD patients as less specific and less emotional than those of matched nonneurologic control subjects. This was true for episodes in response to emotional as well as nonemotional cue words. RHD patients' own ratings of these episodes, however, did not differ from those of controls. These findings are discussed in terms of RHD patients' overall difficulties in processing emotional material and in terms of the nature of autobiographical memory.     

Recognition and discrimination of emotional faces and pictures

In order to learn whether patients with right-hemisphere disease (RHD) had a deficit in their ability to discriminate and comprehend emotional faces and pictures, we studied nine patients with RHD, nine patients with left-hemisphere disease (LHD), and nine controls. The subjects were presented with six picture tests that comprised either emotional faces or emotional scenes. Their task was either to denote (name or choose) an emotion or to discriminate (same, different) between two faces or emotions. Patients with RHD performed significantly worse than subjects with LHD when asked to discriminate between faces, to discriminate between emotional faces, and to name emotional scenes. There was also a trend for the RHD group to be more impaired than the LHD group when asked to name the emotional face or choose the emotional face. Except for the facial and emotional discrimination tests, the LHD patients also performed worse than controls.     

Interactional patterns of bipolar patients and their spouses

This study examined the interactional patterns of eight bipolar patients (when manic and in remission) and their spouses by videotaping the couples' interactions and then quantifying those interactions using the Marital Interaction Coding system. These couples' interactions were compared to the interactions of eight happily and eight unhappily married nonbipolar psychiatric control patients and their spouses. The purposes were to determine (a) whether the interactional pattern between bipolar patients and their spouses changes or remains the same when the patient is in a manic vs. a nonmanic state and (b) how the interaction patterns of bipolar patients when manic and nonmanic compare to happily and unhappily married nonbipolar psychiatriccontrol patients. Significant differences in interactions were found between manic and nonmanic states, in addition to significant differences between these patients and the control groups. There were also expected differences between happily and unhappily married psychiatric control groups. Implications are discussed for marital therapy for manies that involves problemsolving and communication training.     

The use of pronoun anaphora and speaker mood in the interpretation of conversational utterances by right hemisphere brain-damaged patients.

Understanding utterances in conversations requires a listener to weigh the disparate pieces of information present in a discourse. In this study, we examined how right hemisphere brain-damaged (RHD) patients and non-brain-damaged control subjects interpreted responses to questions concerning the location of a person (e.g., "Where's Dad?"). Stimulus vignettes included variation on three factors relevant to discourse comprehension: the mood of a speaker, the plausibility of the answer to a question, and whether the answer contained an anaphoric pronoun linking the response to the preceding question. Relative to the control subjects, the RHD patients made greater than normal use of the presence/absence of an anaphoric pronoun in their utterance interpretations, less than normal use of the speaker's mood, and marginally less than normal use of a response's plausibility. These data show how RHD patients rely on their largely intact linguistic abilities when understanding discourse and how their comprehension goes awry due to their reduced appreciation of other essential aspects of natural communication. The discussion focuses on the variable roles of speaker mood, plausibility, and pronoun anaphora in supporting inferences about a speaker's intended meaning and on the selective nature of RHD patients' impairment in this domain.     

Appreciation of indirect requests by left- and right-brain-damaged patients: the effects of verbal context and conventionality of wording

Unilaterally right (RHD)- and left (LHD)-hemisphere-damaged patients were tested on their ability to discern the correct, nonliteral interpretation of indirect requests (e.g., "Can you open the door?") embedded in short vignettes and presented without any pictorial support. Each stimulus vignette incorporated two verbal cues--context and conventionality of form--designed to influence interpretations of a critical utterance located at the end of each vignette. Contexts were biased to encourage either the direct, literal reading of critical utterances as a question, or the indirect meaning of the utterance as a request for action. The critical utterances themselves were either high in conventionality (e.g., "Can you ...?") which encouraged an indirect interpretation, or low in conventionality (e.g., "Is it possible for you to ...?") which encouraged a direct interpretation. Results indicated that RHD patients were significantly impaired, relative to controls, in their ability to make judgments based on contextual information. RHD patients performed comparably to the aphasic, LHD group in the use of both context and conventionality. These results replicate earlier findings of disrupted indirect request comprehension by RHD patients tested in pictorially supported paradigms.     

Spousal understanding and marital satisfaction in pain patients and their spouses

The current study tested the hypotheses that knee osteoarthritis (OA) patients and spouses who report more spousal understanding of patient's pain would report greater marital satisfaction. A total of 124 couples completed interviews at three time points across 18 months. Results from dyadic analyses showed that patients who felt more understood by their spouse report, and have spouses who report, higher marital satisfaction concurrently. In addition, patients who felt more understood by their spouse reported higher marital satisfaction over time. Spouses' reports of understanding also had a significant influence on the patients' and their own marital satisfaction concurrently. Results highlight the importance of spouses understanding knee OA patients' pain for both dyad members' marital satisfaction.     

Patterns of apraxia associated with the production of intransitive limb gestures following left and right hemisphere stroke

The model of apraxia proposed by Roy (1996) states that three patterns of apraxia should be observed across pantomime and imitation conditions. In the present analysis the frequency and severity of each pattern of apraxia were examined in a consecutive sample of left-(LHD) and right-hemisphere-damaged (RHD) patients during the production of intransitive limb gestures. The results indicated that a significant proportion of LHD and RHD patients were selectively impaired in formulating the ideational component of intransitive limb gestures.     

Queens and Jesters of YouTube: Communicating Gay/Lesbian Identities Through Humor in YouTube Channel <Emphasis Type="Italic">Spanish Queens</Emphasis>

Considering the transformative potential humor has for minorities who experience exclusion and marginalization, I seek to explore how Spanish gay and lesbian youth construct and communicate gay/lesbian identities using humor as a rhetorical tool. Furthermore, I explore the potential implications of their use of humor for social relations, both within gay and lesbian communities and with the broader society. I approach this discussion though a critical discourse analysis of videos from Spanish Queens—a collaborative YouTube channel, in which LGBTQ youth from diverse parts of the country share their experiences, thoughts, and opinions about being LGBTQ in Spain. Stereotypical humor was the primary form of humor used by SQ vloggers when addressing gay and lesbian issues related to both identification and social relations. Looking at how SQ vloggers most frequently use stereotypical humor, three common functions emerged in all ten videos: (a) affirming identity and separating gay and lesbian experiences from those of other groups, including making a distinction between sexual orientation and gender identity; (b) challenging the conflation of sexual and gender identities (i.e., contesting the notion of gay men and lesbians identifying as members of the opposite sex); and (c) disarming discourses that construct gay and lesbian individuals as threats at both interpersonal and societal levels.
