Asymmetric switch-costs and ERPs reveal facial identity dominance over expression

Previous studies on face processing have revealed an asymmetric overlap between identity and expression, as identity is processed irrespective of expression while expression processing partly depends on identity. To investigate whether this relative interaction is caused by dominance of identity over expression, participants performed familiarity and expression judgments during task switching. This paradigm reveals task-set dominance with a paradoxical asymmetric switch-cost (i.e., greater difference between switch and repeat trials when switching toward the dominant task). Event-related potentials (ERPs) were recorded to find the neural signature of the asymmetric cost. As expected, greater switch-cost was shown in the familiarity task with respect to response times, indicating its dominance over the expression task. Moreover, a left-sided ERP correlate of this effect was observed at the level of the frontal N2 component, interpreted as an index of modulations in endogenous executive control. Altogether, these results confirm the overlap between identity and expression during face processing and further indicate their relative dominance.     

Using generalizability theory to estimate the relative effect of class size and number of items on the dependability of student ratings of instruction

Previous research on the effect of class size on student ratings of instruction has primarily investigated the effect of class size on the favorableness of these ratings rather than its effect on their reliability (dependability). A few studies have used "generalizability theory" to demonstrate the relative effect of class size on the dependability of student ratings of instruction. The purpose of the present study was to test the validity of the findings of these studies in a different cultural setting using a different student ratings questionnaire. Using a random-effect analysis of variance to estimate the variance components for a design in which students were nested within classes and crossed with items, it was found that the variance component for class size was appreciably larger than that for items. At least 20 students were needed to obtain a generalizability coefficient for relative decisions of .70 or more. Increasing the number of students has a greater effect on generalizability coefficients than increasing the number of items.     

The size coding of responses: The size of switches and the force feedback

We aimed to understand which factors have a functional role in the size coding of responses, either the size of the switches or the force required to trigger each switch. This question is of relevance because it allows a better understanding of processes underlying action coding. In each trial, participants saw a small or large object. Depending on its colour, the participants had to press one of two switches. In the “size” condition, the response device consisted of two switches of different visual size, but both required the same amount of force. In the “force-feedback” condition, the response device consisted in two switches of identical visual size, but one switch required more force than the other. We found a compatibility effect in the “size,” not in the “force-feedback” condition, supporting that the size-coding of responses would be due to the size of the switches.     

A Fuzzy Goal Programming Formulation with Multiple Target Levels

The essential activity of a manager is decision making, which is becoming more and more complex, mainly in the multi‐criteria problems. Multi‐choice goal programming (MCGP) is considered as a robust tool in operational research to solve this type of problem. However, in real world problems, determining precise targets for the goals is a difficult task. To deal with such situation, Tabrizi introduced and used in 2012 the concept of membership functions in the MCGP model in order to model the targets fuzziness of each goal. In their model, they considered just only one type of functions (triangular form), which does not reflect adequately the decision maker's preferences that are considered as an essential element for modelling the goal's fuzziness. Their model is called Fuzzy MCGP. In this paper, new ideas are presented to reformulate MCGP model to tackle all types of functions by introducing the (decision maker's) preferences. The concept of indifference thresholds is used in the new formulation for characterizing the imprecision and the preferences associated with all types of the goals. The proposed formulation provides useful insight about the solution of a new class of problems. A numerical example is given to demonstrate the validity and strength of the new formulation.

Effects of training condition on the contribution of specific items to relational processing in baboons (Papio papio)

Relational processing involves learning about the relationship between or among stimuli, transcending the individual stimuli, so that abstract knowledge generalizable to novel situations is acquired. Relational processing has been studied in animals as well as in humans, but little attention has been paid to the contribution of specific items to relational thinking or to the factors that may affect that contribution. This study assessed the intertwined effects of item and relational processing in nonhuman primates. Using a procedure that entailed both expanding and contracting sets of pictorial items, we trained 13 baboons on a two-alternative forced-choice task, in which they had to distinguish horizontal from vertical relational patterns. In Experiment 1, monkeys engaged in item-based processing with a small training set size, and they progressively engaged in relation-based processing as training set size was increased. However, in Experiment 2, overtraining with a small stimulus set promoted the processing of item-based information. These findings underscore similarities in how humans and nonhuman primates process higher-order stimulus relations.     

Medical Trainees’ Readiness for the Promotion of Sexual Health in Tunisia: A Cross Sectional Study

In the Arab and Muslim countries, there are several taboos of sexuality. To overcome the latter, and to distinguish between cultural and scientific data, sexual education is a key measure, especially during medical studies. The purpose of this study was to assess the knowledge of the Tunisian medical trainees and to identify their sources of information concerning sexuality. We conducted a survey among medical trainees of the faculty of medicine of Sfax, in Tunisia. An anonymous questionnaire was distributed to 171 and completed by 157 trainees (91.8%). The sources of knowledge about sexuality were: friends (81.5%; N = 128), internet (77.1%; N = 121), television and movies (68.2%; N = 107), courses at the faculty (40.1%; N = 63) and parents (22.9%; N = 36). The score of correct answers was higher than or equal to 75% for 28 trainees (17.8%). It was on average 63.3%. It was correlated with male gender (p = 0.006), being a second-year trainee (p = 0.017) and television and movies as a source of knowledge about sexuality (p = 0.008). Masturbation was considered pathological by 17.2% of participants (N = 27). A 5-min period of intercourse was deemed sufficient to have a female orgasm by 44 trainees (28%). Andropause and menopause are inconsistent with a satisfying sexuality according to 44.6% (N = 70) and 56.1% (N = 88) of the participants respectively.     

The use of religion in coping with grief among bereaved Malay Muslim parents

The purpose of this study is to explore the influence of religion on bereaved parents after the death of a child. Literature had attempted to understand how religiosity may influence parental grief both in positive and negative ways. However, this area is scarcely explored in the Malaysian context. This qualitative study involved 11 bereaved parents who lost their children due to accidents (n?=?9) and homicide (n?=?2). Open-ended questions that focused on the importance, activities, and role of religion in the grieving process among Malay parents were asked. According to the thematic analysis, some of the main themes found were that the bereaved parents described religion as a beneficial mechanism in helping them to adapt with their losses through various responses that indicated the perception that religion as a guidance. However, other than the positive impact, religiosity can also lead the bereaved parents to experience negative effects of using religion as a coping strategy. The influence of culture is prevalent in the current study as the theme of mystical belief and paranormal experiences were also reported. This study provides some professional implication from the possible use of religion in intervention.     

“For Every Illness There is a Cure”: Attitudes and Beliefs of Moroccan Muslim Women Regarding Health,Illness and Medicine

In order to provide adequate health care, it is important to be well aware of the views and attitudes of the health seeker regarding health, illness and medicine. In the Belgian context, the views of Muslim women, particularly of middle-aged and elderly Moroccan women, have been understudied. The aim of this article is twofold. First, we seek to bring forward the attitudes and beliefs of middle-aged and elderly Moroccan Muslim women living in Antwerp (Belgium) towards health, illness and medicine. Second, we seek to explore which role religion plays in their views and attitudes regarding health, illness and medicine. Qualitative empirical research was conducted with a sample of middle-aged and elderly Moroccan Muslim women living in Antwerp (Belgium) (n = 30) and with experts in the field (n = 15). In-depth interviews and participant observations were conducted to reveal their perceptions regarding health, illness and medicine. This study reveals that religion plays a crucial role in how Muslim women perceive and deal with illness. Theological considerations that centre on God’s omnipotence, the belief in the afterlife and religious virtues take up a central position. A holistic approach is adopted in the search for healing, i.e. an interplay between calling upon medicine and turning to God. Religious beliefs seem to be a powerful source in coping with illness.     

The Community Story,Relationality and Process: Bridging Tools for Researching Local Knowledge in a Peri‐urban Township

In intervening in social challenges impacting local communities, Western forms of dispute/conflict resolution have been critiqued for imparting norms, values and practices that marginalise worldviews of indigenous people. From a decolonizing stance, indigenous scholars have emphasised the need for recovery of ‘lost’ values, beliefs and practices to advance indigenous knowledge. We highlight some of the conceptual challenges associated with applying ‘indigenous knowledge’ and culture‐specific ‘indigenous methodologies’ to a marginalised peri‐urban, ethnically plural township community situated on the outskirts of Johannesburg, South Africa. In embracing the mutuality of indigenous and Western knowledge forms, we explore three elements: the community story, relationality and process in relation to initial engagements with our study community. We attempt to transcend the dualism between ‘Western’ epistemologies and ‘indigenous knowledge’ through these ‘bridging concepts’. What is offered is not a formula or model but an orientation that aims to foster mutual learning through collaborative partnerships within and between communities and researchers with a view to inspiring possibilities for creative and meaningful solutions for violence prevention and dispute/conflict resolution.
