The relationship between reward context and inhibitory control, does it depend on BMI, maladaptive eating, and negative affect?

Background Recent studies suggest that higher Body Mass Index (BMI) is associated with reduced inhibitory control in contexts of palatable food. However, due to limitations of previous studies, it remained the question whether this reduction is specific to food contexts, and whether it generalizes to other contexts of reward, such as money. This main question was addressed in the current study. In addition, we explored the effect of maladaptive eating and stress regarding inhibitory control across the contexts that differed in terms of reward. Methods In total, 46 participants between 19 and 50 years old (39% males and 61% females) with an average BMI of 23.5 (SD = 3.9) participated. Participants filled out questionnaires and performed a go/no-go task (indexing inhibitory control) with three conditions (neutral, food, and money condition). Results Relatively high (above median) BMI was associated with challenged inhibitory control in the food relative to the neutral context, but not in the money relative to neutral context. Explorative analyses suggested that maladaptive eating and stress were associated with reduced inhibitory control in the food context. Only rumination was associated with reduced inhibitory control in the money context. Conclusions The effects of BMI, maladaptive eating behavior, and stress on inhibitory control were specific to the food context, and did not generalize to a non-intrinsic reward condition, operationalized with money pictures. Our results imply that (research on) interventions directed at improving inhibitory control in relation to overweight and obesity, should consider food-reward context.

Translating deictic motion verbs among Bulgarian, Croatian, and Serbian: A corpus-based study

This article deals with translating South Slavic deictic verbs. Specifically, we consider translations among Bulgarian, Croatian, and Serbian. Deictic verbs are verbs whose interpretation is dependent on the location of speech-act participants (Fillmore 1997), such as come and go. In research on Slavic, certain motion verbs prefixes have been discussed as deictic prefixes (see Grenoble 1991, Filipović 2009, Łozińska 2018). Particular emphasis in this analysis is on the prefixed motion verbs dojda/doći, idvam/dolaziti, otida/otići, and otivam/odlaziti found in Bulgarian, Croatian, and Serbian literary texts and their translations. We present a brief quantitative overview and conduct a qualitative study of deixis-related meanings, paying necessary attention to other non-deictic meanings. Special attention is given to the constructional interplay of various deictic elements that co-occur with deictic verbs. Since we deal with literary texts and not everyday interaction, we consider the genre and context and apply the notion of viewpoint, which also covers the mental viewpoint adopted by the narrator, in addition to the deictic viewpoint of one of the speech participants. In the study, we observed shifts in point-of-view from deictic to non-deictic construal and vice versa, and from dynamic to static construal. These phenomena relate to the fact that in a text with a third person narrator, there is no innate deictic centre, while in casual conversation, the interlocutors create the deictic centre. The results show a preference for using come when motion towards a protagonist is described in a neutral context.

Inhibitory Performance in Smokers Relative to Nonsmokers When Exposed to Neutral, Smoking- and Money-Related Pictures

Introduction: Smoking is associated with significant negative health consequences. It has been suggested that deficient inhibitory control may be implicated in (nicotine) addiction, but its exact role has not yet been elucidated. In the current study, our aim was to investigate the role of inhibitory control in relation to nicotine addiction in contexts that differ in terms of reward. Methods: Participants filled out questionnaires and performed a go/no-go task with three conditions. In one condition, the stimuli were neutral color squares, and in the reward conditions, these were smoking-related pictures and money-related pictures, respectively. In total, 43 non-abstinent individuals that smoke and 35 individuals that do not smoke were included in the sample. Results: The main results showed that individuals that smoke, relative to individuals that do not smoke, had reduced inhibitory control in both reward contexts, relative to a neutral context. The reductions in inhibitory control were mirrored by speeded responses. Conclusions: Individuals that smoke seem to present with reduced inhibitory control, which is most pronounced in contexts of reward. Consistent with incentive sensitization theory, the reduced inhibitory control may be (at least partly) due to the heightened approach bias to reward-related stimuli as indicated by the speeded responses.

Inoculating against the spread of Islamophobic and radical-Islamist disinformation

We report the results of a preregistered study that tested the effectiveness of inoculating participants against Islamophobic and radical-Islamist disinformation. Participants in the experimental (inoculation) condition watched a video that explained common rhetorical markers of radical-Islamist and Islamophobic disinformation that had been identified in an analysis of YouTube content. The information was presented in a neutral context not involving Islam and focused on analysis of the misleading argumentation. The control group watched a video about an unrelated topic. Participants were then exposed to target videos with “gateway” content that constituted an entry point to potential Islamist or Islamophobic radicalization. Both videos contained numerous items of disinformation. Participants then answered a variety of questions such as how likely they were to share the video, their level of agreement, and their perceived accuracy of the video. Participants who had received the inoculation displayed less agreement with the video content, perceived the video as less reliable, and were less likely to share it in comparison with participants in the control group. The study provides support for the use of argument-based inoculation in combatting extremist messages.

When and Why Contexts Predict Unethical Behavior: Evidence From a Laboratory Bribery Game

In economic unethical decision-making experiments, one important methodological investigation is what types of contexts should be used to frame the instructions. Within the experimental economics community, using neutral-context instructions instead of loaded-context instructions is the mainstream practice. Because the loaded contexts may impact behavior in an unpredictable manner and therefore, put experimental control at risk. Nevertheless, using the loaded-context instructions could be advantageous in several ways. A properly framed context can help to facilitate learning and gain ecological validity. The challenge is whether we can identify when and why the loaded context may alter behavior. In this paper, we aim to test if being familiar with a loaded context can systematically influence unethical decisions in a bribery game. We conduct a laboratory bribery game experiment with three different treatments: the neutral-context treatment, the familiar-context treatment, and the unfamiliar-context treatment. Using the neutral-context treatment as a benchmark, we find that participants in the familiar-context treatment express stronger negative attitudes toward corruption. Attitudes toward unethical behavior are the same in the neutral-context treatment and the unfamiliar-context treatment. Behaviorally, the participants in the familiar-context treatment are much less likely to engage in corrupt activities. The neutral-context treatment and the unfamiliar-context treatment produce the same behavioral outcome.

The effects of emotional context and exposure frequency on L2 contextual word learning

Objectives: An experiment was conducted to explore how emotional valence of contexts and exposure frequency of novel words affect second language (L2) contextual word learning. Methodology: Chinese native speakers who learned English in a formal classroom setting were asked to read English paragraphs with different emotional valence (positive, negative or neutral) across five different days. These paragraphs were embedded with pseudowords. During this learning process, form recognition test and meaning recall test were carried out for these pseudowords. Data and analysis: Data were analyzed using mixed-model ANOVA. Accuracy for each task was compared among the three kinds of emotional contexts. Findings/Conclusions: In the form recognition test, the accuracy in the negative context was higher than in the positive and neutral contexts, and the pseudowords were acquired much earlier. In the meaning recall test, the accuracy in the positive and negative contexts was higher than that in the neutral context. Accuracy increased gradually with the increase of exposure frequency of the pseudowords. More importantly, we found that less exposure times were needed for emotional context relative to neutral context in contextual word learning. Originality: This may be the first study to explore the influence of emotional valence and exposure frequency on L2 contextual word learning. Significance/Implications: This study underlined the importance of emotional information in L2 contextual word learning and contributed to the understanding of how emotional information and exposure frequency functions in this learning process.

Neural Processing of Cognitive Control in an Emotionally Neutral Context in Anxiety Patients

Impaired cognitive control plays a crucial role in anxiety disorders and is associated with deficient neural mechanisms in the fronto-parietal network. Usually, these deficits were found in tasks with an emotional context. The present study aimed at investigating electrophysiological and vascular signatures from event-related brain potentials (ERPs) and functional near-infrared spectroscopy (fNIRS) in anxiety patients versus healthy controls during an inhibition task integrated in an emotionally neutral context. Neural markers were acquired during the completion of a classical Eriksen flanker task. The focus of data analysis has been the ERPs N200 and P300 and fNIRS activations in addition to task performance. No behavioral or neural group differences were identified. ERP findings showed a larger N2pc and a delayed and reduced P300 for incongruent stimuli. The N2pc modulation suggests the reorienting of attention to salient stimuli, while the P300 indicates longer lasting stimulus evaluation processes due to increased task difficulty. FNIRS did not result in any significant activation potentially suggesting a contribution from deeper brain areas not measurable with fNIRS. The missing group difference in our non-emotional task indicates that no generalized cognitive control deficit but rather a more emotionally driven deficit is present in anxiety patients.

Context Matters for Tone and Intonation Processing in Mandarin

In tonal languages such as Mandarin, both lexical tone and sentence intonation are primarily signaled by F0. Their F0 encodings are sometimes in conflict and sometimes in congruency. The present study investigated how tone and intonation, with F0 encodings in conflict or in congruency, are processed and how semantic context may affect their processing. To this end, tone and intonation identification experiments were conducted in both semantically neutral and constraining contexts. Results showed that the overall performance of tone identification was better than that of intonation. Specifically, tone identification was seldom affected by intonation information irrespective of semantic contexts. However, intonation identification, particularly question intonation, was susceptible to the final lexical tone identity and affected by the semantic context. In the semantically neutral context, questions ending with a rising tone and a falling tone were equally difficult to identify. In the semantically constraining context, questions ending with a falling tone were much better identified than those ending with a rising tone. This perceptual asymmetry suggests that top-down information provided by the semantically constraining context can play a facilitating role for listeners to disentangle intonational information from tonal information, but mainly in sentences with the lexical falling tone in the final position.

Challenges Associated With the Assessment of Exposure to Ageism

Ageism is defined as stereotypes, prejudice and discrimination towards people of any age. Ageism can be both positive and negative. In order for an individual to report exposure to ageism, several steps should occur: the individual has to notice the events, interpret them as ageist and report exposure to ageism. Any of these steps may go awry along the way. This presentation uses data from the European Social Survey and the Health and Retirement Study to illustrate the importance of item placement, item phrasing and respondent’s mood in responding to items concerning perceived exposure to ageism. A strong priming effect demonstrated a gap between reports of perceived exposure within the ageism module (33.7%) vs. reports within the neutral context (1.1%). A cross-lagged analyses revealed that one’s depressive symptoms are predictive of perceived exposure to ageism and not the other way around. Findings illustrate the importance of the context effect.

Funkcja politycznych słów kluczy w memach internetowych

The subject of the study is the role of political key words used in memes. To determine their role, a semantic and stylistic analysis of Polish-language memetic statements from 2012–2019 was used, in which the following words were included: sorrel, mirabelles, trotyl, octopuses, light bulb, salad. The article shows that the use of key words even in a completely neutral context allows us to activate references to negatively evaluated events and situations, and to recall the emotions and views associated with them. In addition, quoting chronologically diverse examples of the use of key words has lead to the possibility of recreating the process of extending their meanings, which is the result of releasing quotes associated with a specific situation from their function.
