RESUMEN

In this commentary I provide a review of the microaggression construct within a linguistic-pragmatic framework. From this perspective, microaggressions can be viewed as nonconventional indirect speech acts, that is, utterances that, because of their aggressive meaning, require some type of inferential processing on the part of the hearer. This inferential process requires a consideration of the remark in the context within which it occurs, including the prior discourse, as well as the roles and statuses of the interactants. Because microaggressions are indirect, the speaker always has the option, especially if they are higher in power, of denying any aggressive meaning. Focusing on their linguistic/pragmatic features allows for the development of a more principled framework for specifying what constitutes a microaggression, as well as helping to identify the relevant features of the context and the processes involved in the recognition of microaggressions.

RESUMEN

Successful language use requires accurate intention recognition. However, sometimes this can be undermined because communication occurs within an interpersonal context. In this research, I used a relatively large set of speech acts (n = 32) and explored how variability in their inherent face-threat influences the extent to which they are successfully recognized by a recipient, as well as the confidence of senders and receivers in their communicative success. Participants in two experiments either created text messages (senders) designed to perform a specific speech act (e.g., agree) or interpreted those text messages (receivers) in terms of the specific speech act being performed. The speech acts were scaled in terms of their degree of face threat. In both experiments, speech acts that were more threatening were less likely to be correctly recognized than those that were less threatening. Additionally, the messages of the more threatening speech acts were longer and lower in clout than the less threatening speech acts. Senders displayed greater confidence in communicative success than receivers, but judgments of communicative success (for both senders and receivers) were unrelated to actual communicative success. The implications of these results for our understanding of actual communicative episodes are discussed.

RESUMEN

In face-to-face communication there are multiple paralinguistic and gestural features that facilitate recognition of a speaker's intended meaning, features that are lacking when people communicate digitally (e.g., texting). As a result, substitutes have emerged (expressive punctuation, capitalization, etc.) to facilitate communication in these situations. However, little is known about the comprehension processes involved in digital communication. In this research we examined the role of emoji in the comprehension of face-threatening, indirect replies. Participants in two experiments read question-reply sequences and then judged the accuracy of interpretations of the replies. On critical trials the reply violated the relation maxim and conveyed a negative, face-threatening response. On one-third of the trials the reply contained only text, on one-third of the trials the reply contained text and an emoji, and on one-third of the trials the reply contained only an emoji. When the question requested potentially negative information about one of the interactants (disclosures and opinions), participants were more likely to endorse the indirect meaning of the reply, and did so faster, when the reply contained an emoji than when it did not. This effect did not occur when the question was a request for action, a more conventional type of indirect reply. Overall, then, this research demonstrates that emoji can sometimes facilitate the comprehension of meaning. Future research is needed to examine the boundary conditions for this effect.

RESUMEN

Ambiguity in language derives, in part, from the multiple motivations that underlie the choice to use any particular expression. The use of some lexical items, such as probability expressions and scalar terms, can be motivated by a desire to communicate uncertainty as well as a desire to be polite (i.e., manage face). Research has demonstrated that the interpretation of these items can be influenced by the existence of a potential politeness motive. In general, communications about negative events, relative to positive events, result in higher likelihood estimates whenever politeness can be discerned as a potential motive. With few exceptions, however, this research has focused only on the hearer. In the present research we focused on the dyad and examined whether speakers vary their messages as a function of politeness, and the effect that this has on subsequent judgments made by a recipient. In two experiments we presented participants with situations that varied in terms of face-threat and asked them how they would communicate potentially threatening information. Both experiments included a second set of participants who read these utterances and provided judgments as to the degree of uncertainty conveyed by the utterance. In both experiments, messages in the face-threatening condition conveyed greater uncertainty than messages in the non-face-threatening condition, and the probability estimates made by the second set of participants varied as a function of conveyed uncertainty. This research demonstrates that when examining speakers and hearers together, severe events may be judged less likely (rather than more likely), because speakers tend to hedge the certainty with which they communicate the information.

RESUMEN

Correlations between the relative speeds of left-to-right and right-to-left interhemispheric transfer times and resting quantitative electroencephalography activity were examined in order to determine if variability in interhemispheric transfer was related to individual variability in resting neural firing patterns. Resting electroencephalograph frequencies for 32 participants were regressed for 4 frequency bands at 8 different locations calculated for asymmetrical activation through subtracting the left from right average spectral power of each. Participants also completed a series of behavioural tasks that are typically localized to the right hemisphere (RH). Results indicate that the frontal medial average spectral power of the beta band is correlated with the speed of transfer such that larger resting beta values in the right as compared to left location are associated with faster right-to-left interhemispheric transfer times and that larger resting beta values in the left as compared to right location are associated with faster left-to-right interhemispheric transfer times. Furthermore, enhanced performance on tasks typically localized to the RH is correlated with slower right-to-left interhemispheric transfer times, suggesting that the dominance of one hemisphere may come at a cost to interhemispheric communication.

RESUMEN

Four experiments were conducted to examine the effect of responding to self-report items framed with either a cognitive verb (think) or an affective verb (feel). Participants' open-ended self-descriptions were significantly more negative when they responded to a feel prompt than when they responded to a think prompt (Experiments 1 and 2). This effect persisted and influenced scores on a subsequent measure of self-esteem (Experiment 2). Substituting the verb think for feel in the Rosenberg self-esteem scale resulted in significantly higher reported self-esteem for female participants but not for male participants (Experiments 3 and 4). The research contributes to the literature demonstrating the subtle effects of word choice on responses to self-report items.

RESUMEN

Uncertainty terms (e.g., some, possible, good, etc.) are words that do not have a fixed referent and hence are relatively ambiguous. A model is proposed that specifies how, from the hearer's perspective, recognition of facework as a potential motive for the use of an uncertainty term results in a calibration of the intended meaning of that term. Four experiments are reported that examine the impact of face threat, and the variables that affect it (e.g., power), on the manner in which a variety of uncertainty terms (probability terms, quantifiers, frequency terms, etc.) are interpreted. Overall, the results demonstrate that increased face threat in a situation will result in a more negative interpretation of an utterance containing an uncertainty term. That the interpretation of so many different types of uncertainty terms is affected in the same way suggests the operation of a fundamental principle of language use, one with important implications for the communication of risk, subjective experience, and so on.

RESUMEN

Prior research has demonstrated that semantic organization in the right hemisphere (RH) is more diffuse and specialized for distant semantic associates than is semantic organization in the left hemisphere (LH). The present research explored individual differences in this regard. If the RH is more specialized for distant semantic associates, then individuals with a more active RH should display greater activation of distant semantic associations. Two experiments were conducted to examine this issue. In both studies a line bisection task was used to assess arousal asymmetry. In Experiment 1, greater RH activation was associated with the ability to generate remote associates to three word stimuli. In Experiment 2, relatively greater RH activation was associated with enhanced priming of distant semantic associates. Taken together, these experiments demonstrate that arousal asymmetry is an individual difference variable that is related to variability in semantic organization and retrieval.

RESUMEN

We conducted an exploratory study to examine the resting electroencephalography (EEG) correlates of pseudoneglect, a phenomenon wherein neurologically intact individuals show greater attentional bias toward the left side compared with the right side of space. We took the resting EEG of 21 college students for 5 min and then had them complete a computerized line perception task, during which we asked them to judge the midpoint of horizontal lines on the screen. We computed EEG asymmetry measures for theta, alpha, beta, and gamma frequency bands for each of eight locations (right electrode activity-left electrode activity in the analogous location) and separately regressed these onto the degree of pseudoneglect using stepwise multiple regression analyses. We found significant effects for gamma, theta, and beta bands at location F3/4, indicating greater tonic right midfrontal activation in this location. These findings show that individuals with generally greater right midfrontal resting activation across theta, beta, and gamma bands also demonstrate pseudoneglect during a line perception task. These results lend a novel finding to the pseudoneglect literature, namely an individual differences corollary to current active task observations in the field.

RESUMEN

In this research the role of the RH in the comprehension of speech acts (or illocutionary force) was examined. Two split-screen experiments were conducted in which participants made lexical decisions for lateralized targets after reading a brief conversation remark. On one-half of the trials the target word named the speech act performed with the preceding conversation remark; on the remaining trials the target did not name the speech act that the remark performed. In both experiments, lexical decisions were facilitated for targets representing the speech act performed with the prior utterance, but only when the target was presented to the left visual field (and hence initially processed by the RH) and not when presented to the right visual field. This effect occurred at both short (Experiment 1: 250 ms) and long (Experiment 2: 1000 ms) delays. The results demonstrate the critical role played by the RH in conversation processing.

RESUMEN

Research on the lateralisation of brain functions for emotion has yielded different results as a function of whether it is the experience, expression, or perceptual processing of emotion that is examined. Further, for the perception of emotion there appear to be differences between the processing of verbal and nonverbal stimuli. The present research examined the hemispheric asymmetry in the processing of verbal stimuli varying in emotional valence. Participants performed a lexical decision task for words varying in affective valence (but equated in terms of arousal) that were presented briefly to the right or left visual field. Participants were significantly faster at recognising positive words presented to the right visual field/left hemisphere. This pattern did not occur for negative words (and was reversed for high arousal negative words). These results suggest that the processing of verbal stimuli varying in emotional valence tends to parallel hemispheric asymmetry in the experience of emotion.

RESUMEN

Prior research suggests that people with Parkinson's disease (PD) display certain deficiencies in their use of language. In this research, the authors used a role-playing technique to examine their ability to say things politely and to vary their level of politeness as a function of the social context. PD participants, relative to control participants, produced less polite strategies and failed to vary their politeness as a function of the size of the request. In addition, PD participants who were on high-dosage levels, relative to control and low-dosage PD participants, did not vary their politeness as a function of the recipient's power. Overall, this research demonstrates a deficit in politeness for people with PD, a deficit that most likely plays a role in some of the social deficits that have been demonstrated to occur for people with PD. Potential neurobiological mechanisms of this deficit are discussed.

RESUMEN

We examined potential neurocognitive mechanisms of indirect speech in support of face management in 28 patients with Parkinson's disease (PD) and 32 elderly controls with chronic disease. In experiment 1, we demonstrated automatic activation of indirect meanings of particularized implicatures in controls but not in PD patients. Failure to automatically engage comprehension of indirect meanings of indirect speech acts in PD patients was correlated with a measure of prefrontal dysfunction. In experiment 2, we showed that while PD patients and controls offered similar interpretations of indirect speech acts, PD participants were overly confident in their interpretations and unaware of errors of interpretation. Efficient reputational adjustment mechanisms apparently require intact striatal-prefrontal networks.

RESUMEN

Recognizing the specific speech act (Searle, 1969) that a speaker performs with an utterance is a fundamental feature of pragmatic competence. However, little is known about neurocognitive mediation of speech act comprehension. The present research examined the extent to which people with Parkinson's disease (PD) comprehend specific speech acts. In the first experiment, participants read conversational utterances and then performed a lexical decision task (decide whether a target string of letters was a word). Consistent with past research, nonimpaired participants performed this task more quickly when the target string was the speech act associated with the preceding utterance. In contrast, people with PD did not demonstrate this effect, suggesting that speech act activation is slowed or is not an automatic component of comprehension for people with PD. In a second study, participants were given unlimited time to indicate their recognition of the speech act performed with an utterance. PD participants were significantly poorer at this task than were control participants. We conclude that a previously undocumented language disorder exists in PD and that this disorder involves a selective deficit in speech act comprehension. Frontostriatal systems (the systems impaired in PD) likely contribute to normal speech act comprehension.

RESUMEN

Asymmetric motor severity is common in Parkinson's Disease (PD) and provides a method for examining the neurobiologic mechanisms underlying cognitive and linguistic deficits associated with the disorder. In the present research, PD participants (N=31) were assessed in terms of the asymmetry of their motor symptoms. Interviews with the participants were analyzed with the Linguistic Inquiry and Word Count (LIWC) program. Three measures of linguistic complexity - the proportion of verbs, proportion of function words, and sentence length - were found to be affected by symptom asymmetry. Greater left-side motor severity (and hence greater right-hemisphere dysfunction) was associated with the production of significantly fewer verbs, function words, and shorter sentences. Hence, the production of linguistic complexity in a natural language context was associated with relatively greater right hemisphere involvement. The potential neurobiological mechanisms underlying this effect are discussed.

RESUMEN

This research examined similarities and differences between gambling activities, with a particular focus on differences in gambling frequency and rates of problem gambling. The data were from population-based surveys conducted in Canada between 2001 and 2005. Adult respondents completed various versions of the Canadian Problem Gambling Index (CPGI), including the Problem Gambling Severity Index (PGSI). A factor analysis of the frequency with which different gambling activities were played documented the existence of two clear underlying factors. One factor was comprised of Internet gambling and betting on sports and horse races, and the other factor was comprised of lotteries, raffles, slots/Video Lottery Terminals (VLTs), and bingo. Factor one respondents were largely men; factor two respondents were more likely to be women and scored significantly lower on a measure of problem gambling. Additional analyses indicated that (1) frequency of play was significantly and positively related to problem gambling scores for all activities except raffles, (2) the relationship between problem gambling scores and frequency of play was particularly pronounced for slots/VLTs, (3) problem gambling scores were associated with playing a larger number of games, and (4) Internet and sports gambling had the highest conversion rates (proportion who have tried an activity who frequently play that activity).

RESUMEN

A large, integrated survey data set provided by the Ontario Problem Gambling Centre was used to investigate psychometric properties of the Problem Gambling Severity Index (PGSI). This nine-item self-report instrument was designed to measure a single, problem gambling construct. Unlike its nearest competitor--the South Oaks Gambling Screen (SOGS)--the PGSI was designed specifically for use with a general population rather than in a clinical context. The present analyses demonstrated that the PGSI does assess a single, underlying, factor, but that this is complicated by different, multiple factor structures for respondents with differing levels of problem gambling severity. The PGSI also demonstrated small to moderate correlations with measures of gambling frequency and faulty cognitions. Overall, the PGSI presents a viable alternative to the SOGS for assessing degrees of problem gambling severity in a non-clinical context.

RESUMEN

Social cognition is meant to examine the process of meaningful social interaction. Despite the central involvement of language in this process, language has not received the focal attention that it deserves. Conceptualizing meaningful social interaction as the process of construction and exchange of meaning, the authors argue that language can be productively construed as a semiotic tool, a tool for meaning making and exchange, and that language use can produce unintended consequences in its users. First, the article shows a particular instance of language use to be a collaborative process that influences the representation of meaning in the speaker, the listener, and the collective that includes both the speaker and listener. It then argues that language use and social cognition may have reciprocal effects in the long run and may have significant implications for generating and maintaining cultural differences in social cognition.

RESUMEN

Speakers frequently have specific intentions that they want others to recognize (Grice, 1957). These specific intentions can be viewed as speech acts (Searle, 1969), and I argue that they play a role in long-term memory for conversation utterances. Five experiments were conducted to examine this idea. Participants in all experiments read scenarios ending with either a target utterance that performed a specific speech act (brag, beg, etc.) or a carefully matched control. Participants were more likely to falsely recall and recognize speech act verbs after having read the speech act version than after having read the control version, and the speech act verbs served as better recall cues for the speech act utterances than for the controls. Experiment 5 documented individual differences in the encoding of speech act verbs. The results suggest that people recognize and retain the actions that people perform with their utterances and that this is one of the organizing principles of conversation memory.
