Evidence for a motor mechanism of pain-induced aggression instigation in humans

The automatic skeletal motor responses of 20 male and 20 female student subjects (aged 20–36) receiving a painful stimulation (electric shock) were studied by examining voluntary concomitant extensions and flexions of the arm. These movements were either of long duration, allowing for an on-line control of their execution or, of short duration, requiring extensive pre-programming. Subjects were instructed either to push or to pull a lever upon receipt of an acoustic signal, which was paired or unpaired with an electric shock. Latencies for long duration movements (regardless of direction) were reduced by reception of painful stimulation. Latencies of short duration extensions and flexions were respectively reduced and increased by painful stimulation. Latencies of short duration movements were larger for females than males, regardless of movement direction. These data suggest that painful stimulation elicits automatic movements which affect programming of the termination of simultaneous voluntary movements. Implications of these findings for the study of aggressive behavior are discussed. © 1994 Wiley-Liss, Inc.     

Direction of human motor responses by men and women to aversive stimulation

The frequency of extensions and flexions of the arms of 12 men and 12 women (ages 20-30 years) responding to a neutral tone or to an electric shock was recorded. Subjects had to choose between pushing or pulling a lever upon receipt of an acoustic signal which was paired or unpaired with an electric shock. They were instructed to perform either long duration movements, allowing for on-line control of the execution, or short duration movements with prior specification of amplitude. Regardless of duration of movements, the aversive signal increased the frequency of extensions and intraindividual variability of choices of the men but decreased the frequency of extensions and intraindividual variability of choices of the women. These findings show that stimuli such as pain or fear automatically elicit patterns of terminal motor states corresponding to fight or flight, initiating processes of preparation of spatially oriented movements which are automatic and sex-typed and impair the use of the terminal cues for simultaneous preprogrammed voluntary movements.     

Ethical and Religious Aspects of Gamete and Embryo Donation and Legislation in Iran

During recent decades, new assisted reproductive technologies (ARTs) have improved significantly, but their ethical, social, psychological, religious and legal aspects are blurred and need further research. New techniques using donor sperm or egg allow for third party involvement in the procreation process, which has created new hope for infertile couples. The corresponding clinical applications also raise new religious questions, which require appropriate interpretation in order to make their use possible, particularly in religious communities. In this paper, we discuss the most important ethical issues and the Islamic view of third party reproduction. Likewise, the current method of third party reproduction in Iran will be described, and the advantages and disadvantages of the Act of Embryo Donation to Infertile Spouses will be stated. Consideration of this outlook could generate inspiration in many Islamic countries.     

Premarital sexual, child rearing, and family attitudes of Iranian men and women in the United States and in Iran

Sexual, child rearing, and family attitudes of 160 Iranian immigrants in the United States (61 men, 99 women) and 97 Iranians (55 men, 42 women) in Iran were compared. Iranians in the United States in general, and women in particular, compared with their counterparts in Iran, expressed more permissive attitudes toward premarital sex and sex education, more tolerance toward homosexuality, and a greater acceptance of marital dissolution. Iranians in both countries assigned a high value to the maternal role and to family loyalty but did not endorse unrestricted freedom for youngsters. Influences of attitudinal disparity on interpersonal and family relationships are discussed, and implications for marriage counseling and family therapy are suggested.     

Can Religious Beliefs be a Protective Factor for Suicidal Behavior? A Decision Tree Analysis in a Mid-Sized City in Iran, 2013

This study aimed to assess using tree-based models the impact of different dimensions of religion and other risk factors on suicide attempts in the Islamic Republic of Iran. Three hundred patients who attempted suicide and 300 age- and sex-matched patient attendants with other types of disease who referred to Kerman Afzalipour Hospital were recruited for this study following a convenience sampling. Religiosity was assessed by the Duke University Religion Index. A tree-based model was constructed using the Gini Index as the homogeneity criterion. A complementary discrimination analysis was also applied. Variables contributing to the construction of the tree were stressful life events, mental disorder, family support, and religious belief. Strong religious belief was a protective factor for those with a low number of stressful life events and those with a high mental disorder score; 72 % of those who formed these two groups had not attempted suicide. Moreover, 63 % of those with a high number of stressful life events, strong family support, strong problem-solving skills, and a low mental disorder score were less likely to attempt suicide. The significance of four other variables, GHQ, problem-coping skills, friend support, and neuroticism, was revealed in the discrimination analysis. Religious beliefs seem to be an independent factor that can predict risk for suicidal behavior. Based on the decision tree, religious beliefs among people with a high number of stressful life events might not be a dissuading factor. Such subjects need more family support and problem-solving skills.     

“Weapons effect” revisited: Motor effects of the reception of aversive stimulation and exposure to pictures of firearms

The effect of presenting images of firearms on the speed of clenching of the fist of human subjects simultaneously receiving an aversive stimulation was studied. It was thought that, whereas the classic interpersonal experimental situation confounds the effects of the stimulus presented and several interpersonal processes, speed of fist clenching in a noninterpersonal setting could constitute a valid measure of the subject's readiness to fight. Twenty-four male and 24 female students (ages > 20 and <36 years) were instructed to press with their right hand a device commanding the projection of slides upon reception of an acoustic signal. Speed of clenching of the hand was recorded in the four conditions generated by the combination of two levels of acoustic signal (aversive and nonaversive) and two modalities of slides (firearms or tools). The results show that the reception of aversive sound accelerates fist clenching. Simultaneous presentation of slides of firearms and reception of aversive noise increases the speed of clenching of the fist. The slides' main effect was not significant. More irritable subjects tend to execute this movement faster than their less irritable counterparts, and more emotionally susceptible subjects tend to be slower than less susceptible ones. Male subjects were faster than females. This pattern of results is discussed in relation to the hypothesis formulated by the authors.     

On Iranian EFL Undergraduate Students’ Perceptions of Plagiarism

The fast growing rates of plagiarism among students in higher education has become a serious concern for academics around the world. Collecting data through semi-structured interview, this qualitative study is an attempt to investigate a group of EFL undergraduate students’ viewpoints on plagiarism, the extent to which they are informed about it and the reasons triggering them to plagiarize. Responses revealed shallow understanding of plagiarism in its various forms. The findings indicated a range of contributing factors including: instructors’ ignorance towards plagiarism, limited writing and research skills, peer pressure, pressure to submit high-quality assignments and ease of plagiarizing. The results highlighted the need for practical policies and cohesive framework to raise students’ awareness at initial stages in order to minimize the prevalence of plagiarism at later points. Developing rich writing and referencing skills should be considered seriously by course instructors and the common leniency towards undergraduate students’ instances of plagiarism must be replaced by more serious attitude that encourages innovative and genuine research practice. The implications of findings can help academics to take the required steps in decreasing cases of plagiarism among students.     

Motivational effects of success or failure feedback on the perception of affective pictures

A study of perception of affective pictures from the International Affective Photo System, using the Self Assessment Manikin scale, was conducted. It was hypothesized that participants' affective ratings could be moderated by a subjective experience of success or failure. Analysis, based on a sample of 36 university students, showed an approach tendency for women when they were exposed to positive pictures in the success condition. This approach tendency was associated with relatively shorter processing times and high affective ratings. Men showed relatively shorter processing times and high affective ratings when exposed to negative pictures. For memory-related measures, the highest scores were observed in the success condition for exposure to pleasant pictures. The results are discussed in terms of affective-related self-regulatory tendencies moderated by sex.     

Perceiving gaze from head and eye rotations: An integrative challenge for children and adults

Gaze is an emergent visual feature. A person's gaze direction is perceived not just based on the rotation of their eyes, but also their head. At least among adults, this integrative process appears to be flexible such that one feature can be weighted more heavily than the other depending on the circumstances. Yet it is unclear how this weighting might vary across individuals or across development. When children engage emergent gaze, do they prioritize cues from the head and eyes similarly to adults? Is the perception of gaze among individuals with autism spectrum disorder (ASD) emergent, or is it reliant on a single feature? Sixty adults (M = 29.86 years‐of‐age), thirty‐seven typically developing children and adolescents (M = 9.3 years‐of‐age; range = 7–15), and eighteen children with ASD (M = 9.72 years‐of‐age; range = 7–15) viewed faces with leftward, rightward, or direct head rotations in conjunction with leftward or rightward pupil rotations, and then indicated whether the face was looking leftward or rightward. All individuals, across development and ASD status, used head rotation to infer gaze direction, albeit with some individual differences. However, the use of pupil rotation was heavily dependent on age. Finally, children with ASD used pupil rotation significantly less than typically developing (TD) children when inferring gaze direction, even after accounting for age. Our approach provides a novel framework for understanding individual and group differences in gaze as it is actually perceived—as an emergent feature. Furthermore, this study begins to address an important gap in ASD literature, taking the first look at emergent gaze perception in this population.
