Are there theory of mind regions in the brain? A review of the neuroimaging literature

There have been many functional imaging studies of the brain basis of theory of mind (ToM) skills, but the findings are heterogeneous and implicate anatomical regions as far apart as orbitofrontal cortex and the inferior parietal lobe. The functional imaging studies are reviewed to determine whether the diverse findings are due to methodological factors. The studies are considered according to the paradigm employed (e.g., stories vs. cartoons and explicit vs. implicit ToM instructions), the mental state(s) investigated, and the language demands of the tasks. Methodological variability does not seem to account for the variation in findings, although this conclusion may partly reflect the relatively small number of studies. Alternatively, several distinct brain regions may be activated during ToM reasoning, forming an integrated functional "network." The imaging findings suggest that there are several "core" regions in the network-including parts of the prefrontal cortex and superior temporal sulcus-while several more "peripheral" regions may contribute to ToM reasoning in a manner contingent on relatively minor aspects of the ToM task. © 2008 Wiley-Liss, Inc.

Efeito agudo do exercício aeróbio vigoroso sobre as funções executivas em adolescentes

Executive functions are determinant cognitive processes for student success, since they execute and control complex cognitive activities such as reasoning, planning and solving problems. The development of the executive functions performances begin early at childhood going through the adolescence until adulthood, concomitant with the neuroanatomical, functional and blood perfusion changes over the brain. In this scenario, exercise has been considered an important environmental factor for neurodevelopment, as well as for the promotion of cognitive and brain health. However, there are no large scientific studies investigating the effects of a single vigorous aerobic exercise session on executive functions in adolescents. Objective: To verify the acute effect of vigorous aerobic exercise on executive functions in adolescents. Methods: A randomized controlled trial (RCT) with crossover design was used. 20 pubescent from both sexes/gender with age between 10 and 16 years were submitted to two sessions of 30min each: 1) The aerobic exercise session intensity was between 65 and 75% of heart rate reserve, in which 5min for warm-up, 20min at the target intensity and 5min of cool down; and 2) control session watching cartoons. The computerized Stroop test – Testinpacs and trail making test were used to evaluate the inhibitory control and cognitive flexibility assessment respectively, before and after both experimental and control sessions. The reaction time (RT) and number of errors (n) of Stroop test were recorded. The total time (TT) and the number of errors (n) of the trail making test were also recorded. Results: The control session’s RT did not present significant differences in the Stroop test. On the other hand, the exercise session’s RT decreased significantly (p<0.01) after the session. The number of errors made at the Stroop test had no significant differences in control and exercise sessions. The ΔTT of trail making test of exercise session was significantly (p<0.001) lower than the control session’s. Errors made in trail making test did not show significant differences between control and exercise sessions. Additionally, there was significant and positive association among the Stroop test ΔRT of exercise session with xiii chronological age (r= 0.635, p=0.001; r 2 = 0.404, p=0.003) and sexual maturation (rs= 0.580, p=0.007; r 2 = 0.408, p=0.002). Differently, there was no association among the control session ΔRT and chronological age (r= – 0.144, p=0.273; r 2 = 0.021, p=0.545) or sexual maturation (rs= –0.155, p=0.513; r 2 = 0.015, p=0.610). Conclusion: Vigorous aerobic exercise seems to improve acutely executive functions in adolescents. The effect of exercise on inhibitory control performance was associated to pubertal stage and chronological age. In other words, the benefits of exercise were more evident in early adolescence (↑ ΔRT) and its magnitude decreases along the growing up process.

UMA NARRATIVA MIDIATIZADA DO COTIDIANO: As charges de Política Internacional de Angeli (2001-2012)

Esta pesquisa se insere nas discussões sobre comunicação midiática nas interações sociais. Traz como tema a charge enquanto narrativa midiatizada do cotidiano, a partir de um estudo de natureza bibliográfica e de um exercício de aplicação no qual foram estudadas as charges de Angeli reunidas na coletânea O lixo da história, publicada pela editora Companhia das Letras. Dentre os autores e teorias trabalhadas destacam-se: a conceituação de narrativa, proposta por Luiz Gonzaga Motta; a ideia da midiatização da sociedade, a partir da discussão de José Luiz Braga; a teoria de mediações culturais de Jesús Martin-Barbero; os estudos de cotidiano de Michel de Certeau; e o entendimento de cultura, fundamentado nos Estudos Culturais. A partir das leituras e análise realizadas, a pesquisa trouxe a tona as percepções de que a charge é uma narrativa do absurdo e narrativa absurda de um momento histórico, de maneira a inseri-la enquanto monumento historiográfico do cotidiano. Assim como é feito com as narrativas jornalísticas, a charge demanda uma visão crítica, observando não apenas a sua forma, mas sim o seu contexto.

Peruanos y bolivianos en la sátira chilena de la Guerra del Pacífico (1879 - 1884)

A partir de los grabados publicados en las páginas de los periódicos que incluyeron humor gráfico en sus ediciones durante la Guerra del Pacífico (1879 - 1883), los caricaturistas chilenos desplegaron un discurso visual agresivo en clave patriótica y belicista, donde presentaron a sus lectores una imagen crítica y despectiva respecto de los adversarios de Chile. Recalcaron la supuesta falta de ánimo y valor combativo, ante la sola presencia de los efectivos militares chilenos tanto en el mar como en tierra. Así, la tinta y el papel, se transformaron en otra de las armas que intervinieron en el conflicto de Chile contra el Perú y Bolivia por la posesión de los ricos territorios salitreros de Tarapacá y Antofagasta. Las imágenes fueron interpretadas a partir de los postulados de la Escuela de Warburg, en especial los de Erwin Panofsky, que propone tres niveles de estudio del significado de cada obra, a saber, la “descripción preiconográfica”, luego el “estudio iconográfico” en cuanto tal y, finalmente, la “interpretación iconológica”.

No Joke: Understanding Public Sentiment Toward Selling and Salespeople Through Cartoon Analysis

Unflattering representations of salesmanship in mass media exist in abundance. In order to gauge the depiction of selling in mass media, this article explores the nature and public perceptions of salesmanship using editorial cartoons. A theory of cartooning suggests that editorial cartoons reflect public sentiment toward events and issues and therefore provide a useful way of measuring and tracking such sentiment over time. The criteria of narrative, location, binary struggle, normative transference, and metaphor were used as a framework to analyze 286 cartoons over a 30-year period from 1983 to 2013. The results suggest that while representations of the characteristics and behaviors of salespeople shifted very little across time periods, changes in public perceptions of seller–buyer conflict, the role of the customer, and selling techniques were observed, thus indicating that cartoons are sensitive enough to measure the portrayal of selling.

Tiras cômicas online: mediação e interações na linguagem das tiras

The study aims to analyze comic strips on the internet, from three different artists: Carlos Ruas, creator of "Um Sábado Qualquer", André Farias, of "Vida de Suporte," and William Leite, author of "Willtirando". The discussion covers the relationship between comics and technology by analyzing the comic strip and the construction of its meaning. The qualitative reflection is aggregated by quantitative data, through which the work shows possible outcomes for the language of the online comic strips, such as the expansion in the format; increased hybridization with various types of images; and the approach phenomenon between the spheres author/reader in digital format. Productions of a most unusual kind also were discussed: the digital comic strips, that incorporate animated effects on its narrative. At the end of the study, we present an online comic strip prototype from the most popular formats used by the authors, in order to reiterate the nature of the comic strips: a brief narrative whose outcome is unexpected and results in humor.

Sonic Movie Memories: Sound, Childhood, and American Cinema

Though the trend rarely receives attention, since the 1970s many American filmmakers have been taking sound and music tropes from children’s films, television shows, and other forms of media and incorporating those sounds into films intended for adult audiences. Initially, these references might seem like regressive attempts at targeting some nostalgic desire to relive childhood. However, this dissertation asserts that these children’s sounds are instead designed to reconnect audience members with the multi-faceted fantasies and coping mechanisms that once, through children’s media, helped these audience members manage life’s anxieties. Because sound is the sense that Western audiences most associate with emotion and memory, it offers audiences immediate connection with these barely conscious longings. The first chapter turns to children’s media itself and analyzes Disney’s 1950s forays into television. The chapter argues that by selectively repurposing the gentlest sonic devices from the studio’s films, television shows like Disneyland created the studio’s signature sentimental “Disney sound.” As a result, a generation of baby boomers like Steven Spielberg comes of age and longs to recreate that comforting sound world. The second chapter thus focuses on Spielberg, who incorporates Disney music in films like Close Encounters of the Third Kind (1977). Rather than recreate Disney’s sound world, Spielberg uses this music as a springboard into a new realm I refer to as “sublime refuge” - an acoustic haven that combines overpowering sublimity and soothing comfort into one fantastical experience. The second half of the dissertation pivots into more experimental children’s cartoons like Gerald McBoing-Boing (1951) - cartoons that embrace audio-visual dissonance in ways that soothe even as they create tension through a phenomenon I call “comfortable discord.” In the final chapter, director Wes Anderson reveals that these sonic tensions have just as much appeal to adults. In films like The Royal Tenenbaums (2001), Anderson demonstrates that comfortable discord can simultaneously provide a balm for anxiety and create an open-ended space that makes empathetic connections between characters possible. The dissertation closes with a call to rethink nostalgia, not as a romanticization of the past, but rather as a reconnection with forgotten affective channels.
