The current study investigated whether fiction experiences change empathy of the reader. Based on transportation theory, it was predicted that when people read fiction, and they are emotionally transported into the story, they become more empathic. Two experiments showed that empathy was influenced over a period of one week for people who read a fictional story, but only when they were emotionally transported into the story. No transportation led to lower empathy in both studies, while study 1 showed that high transportation led to higher empathy among fiction readers. These effects were not found for people in the control condition where people read non-fiction. The study showed that fiction influences empathy of the reader, but only under the condition of low or high emotional transportation into the story.
Maxillary protraction with the novel N2 mini-implant- and micro-implant-assisted rapid palatal expander (MARPE) can potentially provide significant skeletal effects without surgery, even in older patients where conventional facemask therapy has limited skeletal effects. However, the skeletal effects of altering the location and direction of force from mini-implant-assisted maxillary protraction have not been extensively analyzed. In this study, the application of the novel N2 mini-implant as an orthopedic anchorage device is explored in its ability to treat patients with class III malocclusions.
While the nonpalpable testis represents only a small portion of all cryptorchid testes, it remains a clinical challenge for pediatric urologists. Many controversies about the best evaluation and management exist. This narrative review serves as an update on what is known about the nonpalpable testis: etiology, pre-operative evaluation, the best surgical management, novel techniques, and ongoing controversies.
Treatment of multidrug-resistant tuberculosis (MDR-TB) is complex, lengthy, and involves a minimum of four drugs termed a background regimen (BR), that have not previously been prescribed or that have proven susceptible to patient sputum culture isolates. In recent years, promising new treatment options have emerged as add-on therapies to a BR. The aim of this study was to evaluate the long-term costs and effectiveness of adding the novel or group 5 interventions bedaquiline, delamanid, and linezolid to a background regimen (BR) of drugs for the treatment of adult patients with pulmonary multidrug-resistant tuberculosis (MDR-TB), within their marketing authorisations, from a German healthcare cost-effectiveness perspective.
Craving is considered a key characteristic of diverse pathologies, but evidence suggests it may be a culture-bound construct. Almost 50% of American women crave chocolate specifically around the onset of menstruation. Research does not support popular accounts implicating physiological factors in menstrual chocolate craving etiology. We tested the novel hypothesis that greater menstrual craving prevalence in the U.S. is the product of internalized cultural norms. Women of diverse backgrounds (n = 275) reported on craving frequency and triggers and completed validated measures of acculturation. Foreign-born women were significantly less likely to endorse menstrual chocolate craving (17.3%), compared to women born to U.S.-born parents (32.7%, p = .03) and second generation immigrants (40.9%, p = .001). Second generation immigrant and foreign-born women endorsing menstrual chocolate craving reported significantly greater U.S. acculturation and lower identification with their native culture than non-menstrual cravers (all p < .001). Findings inform our understanding of food cravings, with important implications for the study of cravings in other domains.

Invention has been commonly conceptualized as a search over a space of combinatorial possibilities. Despite the existence of a rich literature, spanning a variety of disciplines, elaborating on the recombinant nature of invention, we lack a formal and quantitative characterization of the combinatorial process underpinning inventive activity. Here, we use US patent records dating from 1790 to 2010 to formally characterize invention as a combinatorial process. To do this, we treat patented inventions as carriers of technologies and avail ourselves of the elaborate system of technology codes used by the United States Patent and Trademark Office to classify the technologies responsible for an invention’s novelty. We find that the combinatorial inventive process exhibits an invariant rate of ‘exploitation’ (refinements of existing combinations of technologies) and ‘exploration’ (the development of new technological combinations). This combinatorial dynamic contrasts sharply with the creation of new technological capabilities-the building blocks to be combined-that has significantly slowed down. We also find that, notwithstanding the very reduced rate at which new technologies are introduced, the generation of novel technological combinations engenders a practically infinite space of technological configurations.
Readers often describe vivid experiences of voices and characters in a manner that has been likened to hallucination. Little is known, however, of how common such experiences are, nor the individual differences they may reflect. Here we present the results of a 2014 survey conducted in collaboration with a national UK newspaper and an international book festival. Participants (n=1566) completed measures of reading imagery, inner speech, and hallucination-proneness, including 413 participants who provided detailed free-text descriptions of their reading experiences. Hierarchical regression analysis indicated that reading imagery was related to phenomenological characteristics of inner speech and proneness to hallucination-like experiences. However, qualitative analysis of reader’s accounts suggested that vivid reading experiences were marked not just by auditory phenomenology, but also their tendency to cross over into non-reading contexts. This supports social-cognitive accounts of reading while highlighting a role for involuntary and uncontrolled personality models in the experience of fictional characters.
Abstract Background: No prior study has empirically characterized the association between health risks and reading popular fiction depicting violence against women. Fifty Shades-a blockbuster fiction series-depicts pervasive violence against women, perpetuating a broader social narrative that normalizes these types of risks and behaviors in women’s lives. The present study characterized the association between health risks in women who read and did not read Fifty Shades; while our cross-sectional study design precluded causal determinations, an empirical representation of the health risks in women consuming the problematic messages in Fifty Shades is made. Methods: Females ages 18 to 24 (n=715), who were enrolled in a large Midwestern university, completed a cross-sectional online survey about their health behaviors and Fifty Shades' readership. The analysis included 655 females (219 who read at least the first Fifty Shades novel and 436 who did not read any part of Fifty Shades). Age- and race-adjusted multivariable models characterized Fifty Shades' readers and nonreaders on intimate partner violence victimization (experiencing physical, sexual and psychological abuse, including cyber-abuse, at some point during their lifetime); binge drinking (consuming five or more alcoholic beverages on six or more days in the last month); sexual practices (having five or more intercourse partners and/or one or more anal sex partner during their lifetime); and using diet aids or fasting for 24 or more hours at some point during their lifetime. Results: One-third of subjects read Fifty Shades (18.6%, or 122/655, read all three novels, and 14.8%, or 97/655, read at least the first novel but not all three). In age- and race-adjusted models, compared with nonreaders, females who read at least the first novel (but not all three) were more likely than nonreaders to have had, during their lifetime, a partner who shouted, yelled, or swore at them (relative risk [RR]=1.25) and who delivered unwanted calls/text messages (RR=1.34); they were also more likely to report fasting (RR=1.80) and using diet aids (RR=1.77) at some point during their lifetime. Compared with nonreaders, females who read all three novels were more likely to report binge drinking in the last month (RR=1.65) and to report using diet aids (RR=1.65) and having five or more intercourse partners during their lifetime (RR=1.63). Conclusions: Problematic depictions of violence against women in popular culture-such as in film, novels, music, or pornography-create a broader social narrative that normalizes these risks and behaviors in women’s lives. Our study showed strong correlations between health risks in women’s lives-including violence victimization-and consumption of Fifty Shades, a fiction series that portrays violence against women. While our cross-sectional study cannot determine temporality, the order of the relationship may be inconsequential; for example, if women experienced adverse health behaviors first (e.g., disordered eating), reading Fifty Shades might reaffirm those experiences and potentially aggravate related trauma. Likewise, if women read Fifty Shades before experiencing the health behaviors assessed in our study, it is possible that the book influenced the onset of these behaviors by creating an underlying context for the behaviors.
Efference copies refer to internal duplicates of movement-producing neural signals. Their primary function is to predict, and often suppress, the sensory consequences of willed movements. Efference copies have been almost exclusively investigated in the context of overt movements. The current electrophysiological study employed a novel design to show that inner speech - the silent production of words in one’s mind - is also associated with an efference copy. Participants produced an inner phoneme at a precisely specified time, at which an audible phoneme was concurrently presented. The production of the inner phoneme resulted in electrophysiological suppression, but only if the content of the inner phoneme matched the content of the audible phoneme. These results demonstrate that inner speech - a purely mental action - is associated with an efference copy with detailed auditory properties. These findings suggest that inner speech may ultimately reflect a special type of overt speech.
