We report two experiments investigating the effect of working memory (WM) load on selective attention. Experiment 1 was a modified version of Lavie et al. (2004) and confirmed that increasing memory load disrupted performance in the classic flanker task. Experiment 2 used the same manipulation of WM load to probe attention during the viewing of complex scenes, while also investigating individual differences in ADHD traits. In the image viewing task, we measured the degree to which fixations targeted each of two crucial objects: (1) a social object (a person in the scene) and (2) a non-social object of higher or lower physical salience. We compared the extent to which increasing WM load would change the pattern of viewing of the physically salient and socially salient objects. If attending to the social item requires greater default voluntary top-down resources, then the viewing of social objects should show stronger modulation by WM load compared to viewing of physically salient objects. The results showed that the social object was fixated to a greater degree than the other object (regardless of physical saliency). Increased saliency drew fixations away from the background leading to slightly increased fixations on the non-social object, without changing fixations on the social object. Increased levels of ADHD-like traits were associated with fewer fixations on the social object, but only in the high salient, low load condition. Importantly, WM load did not affect number of fixations on the social object. Such findings suggest rather surprisingly that attending to a social area in complex stimuli is not dependent on the availability of voluntary topdown resources.

AbstractAn open question in the working memory (WM) field is how information is kept online during the WM delay period. Maintenance of simple stimuli in WM is supported by connectivity between frontal and parietal brain regions. How does delay period activity and connectivity support WM of complex stimuli? Twenty-two participants completed a modified Sternberg WM task with complex stimuli and were told to remember either 2 (low-load) or 5 (high-load) scenes while 32- channel scalp EEG was recorded. During the 6-sec delay period 6 phase-scrambled scenes were presented, which served as interference. While increasing the WM load, particularly with complex stimuli, places a greater demand on attentional resources, interfering stimuli may hijack the available resources. This was confirmed in the examination of theta and alpha amplitude, as amplitude was reduced for the high WM load as compared with the low WM load across frontal, central, and parietal regions. Delay period connectivity was assessed with phase-locking value (PLV). We identified 3 supporting networks that facilitated performance for the low-load condition: 1) increased PLV between left frontal and right posterior temporal in the theta and alpha bands; 2) increased PLV between right anterior temporal and left central in the alpha and lower beta bands; and 3) increased PLV between left anterior temporal and left posterior temporal in theta, alpha, and lower beta bands for the low-load condition. These results suggest that these brain networks facilitated the low-load WM by filtering of interference and the use of verbal rehearsal during the delay period.Impact StatementAlthough, studies of working memory maintenance with simple stimuli have suggested a role of frontal-parietal networks in supporting maintenance, the current study suggests that maintenance of complex visual stimuli with interference present is supported by interhemispheric frontal-posterior temporal and intrahemispheric left temporal region connectivity. These networks support maintenance by filtering of the interfering stimuli, which facilitates the use of verbal rehearsal strategies during the delay period.

This paper examines how and by whom tellings with two young children are triggered at ages 23, 36 and 42 months. The data for the investigation is derived from a larger Australian English corpus of over 50 hours of interactions in the home, although one of the children is a bilingual Italian/ English-speaking child. The data is derived from two parent/child dyads, and in the case of the child aged 42 months, a triadic interaction between a mother, her own child and a second child. Using the micro-analytic methods of conversation analysis, the study analyses five samples of tellings. The first two describe how a child, Cassandra, aged 23 months, is invited to recount events of her day by her parents. The trigger for these tellings is the social activity of sharing everyday routine events. The next two samples focus on Rosie at 36 months who is also invited to share a telling by her parent about a birthday party celebration and one about a neighbourhood cat, Claude. The first telling is triggered by an object, a balloon from a birthday party from the day before, while the second is triggered by play involving the character of a cat, initially derived from a favourite story, Hairy Maclary. In the final sample, Cassandra, aged 42 months, initiates a telling about an experience at her grandmother’s which is trigged by a picture in a book. The analyses in each case reveal the interactional issues that arise in the action of telling and how these are dealt with by all participants. By focusing on the three ages, key features in the children’s participation in storytelling are uncovered.

Mind wandering, defined as focusing attention toward task unrelated thoughts, is a common mental state known to impair memory encoding. This phenomenon is closely linked to boredom. Very few studies, however, have tested the potential impact of boredom on memory encoding. Thus, the present study aimed at manipulating mind wandering and boredom during an incidental memory encoding task, to test their differential impact on memory encoding. Thirty-two participants performed a variant of the n-back task in which they had to indicate if the current on-screen object was the same as the previous one (1-back; low working memory load) or the one presented three trials before (3-back; high working memory load). Moreover, thought probes assessing either mind wandering or boredom were randomly presented. Afterward, a surprise recognition task was delivered. Results showed that mind wandering and boredom were highly correlated, and both decreased in the high working memory load condition, while memory performance increased. Although both boredom and mind wandering predicted memory performance taken separately, we found that mind wandering was the only reliable predictor of memory performance when controlling for boredom and working memory load. Model comparisons also revealed that a model with boredom only was outperformed by a model with mind wandering only and a model with both mind wandering and boredom, suggesting that the predictive contribution of boredom in the complete model is minimal. The present results confirm the high correlation between mind wandering and boredom and suggest that the hindering effect of boredom on memory is subordinate to the effect of mind wandering.

Due to the coupling of different energy systems, optimization of different energy complementarities, and the realization of the highest overall energy utilization rate and environmental friendliness of the energy system, distributed energy system has become an important way to build a clean and low-carbon energy system. However, the complex topological structure of the system and too many coupling devices bring more uncertain factors to the system which the calculation of the interval power flow of distributed energy system becomes the key problem to be solved urgently. Affine power flow calculation is considered as an important solution to solve uncertain steady power flow problems. In this paper, the distributed energy system coupled with cold, heat, and electricity is taken as the research object, the influence of different uncertain factors such as photovoltaic and wind power output is comprehensively considered, and affine algorithm is adopted to calculate the system power flow of the distributed energy system under high and low load conditions. The results show that the system has larger operating space, more stable bus voltage and more flexible pipeline flow under low load condition than under high load condition. The calculation results of the interval power flow of distributed energy systems can provide theoretical basis and data support for the stability analysis and optimal operation of distributed energy systems.

ABSTRACT Both Lee Man Fong - a male painter - and Chiang Yu Tie - a female painter - are Chinese who migrated to Indonesia. In the beginning of the 20th century, Lee Man Fong lived in Bali while Chiang Yu Tie lived in Java. Many of their artworks were collected by the National Palace and many government officers. The questions of this research are visualization of the women as the object of paintings of both artists and gesture of the women in the paintings of both artists. The purpose of the research is to enrich the documentary infrastructure about women as object in the social area of visual arts which has not been studied much. The research method that will be used is qualitative method with purpose sampling. The result of the research will show that both artists are very familiar with a particular social life during their stay in a certain place, so that their perceptions are focused in excavating the women object in their artworks.Keywords: Chiang Yu Tie, Chinese, Lee Man Fong, Painting, Woman.ABSTRAK Lee Man Fong adalah pelukis laki-laki dan Chiang Yu Tie adalah pelukis perempuan.

When we are interested in the image of a social object, we are interested in what individuals have perceived about that object, the ways in which they have interpreted those perceptions, and what they think about that object. Fully agreeing with the idea that the use of iconographic stimuli can enhance the traditional methods and techniques that are used to study any social representation, in this article, two techniques will be presented. The first, the prototypical stimuli technique, was proposed in the second half of the 1980s by Galli and Nigro. The second technique, iconographic stimuli, creatively integrate images and words in a single tool, was designed more recently to study the social representation of culture by Galli, Fasanelli, and Schember. Researches here reviewed clearly shows that the image has the great power to attract to itself the very objects depicted, a power that the word often does not possess. It is images that make people reflect, help them to think about issues concerning the fundamental aspects of everyday life. The work here presented, carried out in first person by the writer, as well as by all the other authors who are concentrating their efforts in this direction, only represents a starting point of reflection. New and more articulated studies will be able to support with heuristic evidence what so far seems to be configured as a suggestive hypothesis, which in any case will require a wider and shared interdisciplinary effort.

Urban social sustainability represents a more specific part of urban development. Citizen involvement is a vital element of any future urban social development and helps to maintain the vision of human and diverse cities because it provides vibrant and sustainable cities in which everyone has a seat and can speak. Gellerupparken, as something new, also meets all five criteria for when an area is a ghetto during a given year. The criteria generally consist of income, ethnic origin, level of education, crime, and employment. The study’s aim is to present an objective means, to the reactivation of a passive multicultural zone in Aarhus city of Denmark to integrate it in the social life city by using the appreciative inquiry method by an introduction of new city functions. The study will assume the effect of sustainability in an urban social area, in a case study using the application of the pedagogical method, namely, the “appreciative inquiry” method.
