The threat simulation theory of the evolutionary function of dreaming: Evidence from dreams of traumatized children

The threat simulation theory of dreaming (TST) () states that dream consciousness is essentially an ancient biological defence mechanism, evolutionarily selected for its capacity to repeatedly simulate threatening events. Threat simulation during dreaming rehearses the cognitive mechanisms required for efficient threat perception and threat avoidance, leading to increased probability of reproductive success during human evolution. One hypothesis drawn from TST is that real threatening events encountered by the individual during wakefulness should lead to an increased activation of the system, a threat simulation response, and therefore, to an increased frequency and severity of threatening events in dreams. Consequently, children who live in an environment in which their physical and psychological well-being is constantly threatened should have a highly activated dream production and threat simulation system, whereas children living in a safe environment that is relatively free of such threat cues should have a weakly activated system. We tested this hypothesis by analysing the content of dream reports from severely traumatized and less traumatized Kurdish children and ordinary, non-traumatized Finnish children. Our results give support for most of the predictions drawn from TST. The severely traumatized children reported a significantly greater number of dreams and their dreams included a higher number of threatening dream events. The dream threats of traumatized children were also more severe in nature than the threats of less traumatized or non-traumatized children.     

Cognitive discernible factors between schizophrenia and schizoaffective disorder

BACKGROUND: Schizophrenia (SZ) and schizoaffective disorders (SA) are associated with cognitive deficits. Generally, a schizoaffective diagnosis is associated with better prognosis on the level of social integration. It is also well established that cognition is an important factor for good social outcome in schizophrenia. We hypothesized that, although patients suffering from SA share symptoms with SZ, they can be differentiated on the basis of neurocognitive function and that SA perform better in several domains. METHOD: Performances of two groups SA (N = 13) and SZ (N = 44) were compared on several visual-motor tasks using CANTAB [Motor Screening (MOT), Reaction Time (RTI), Paired Associates Learning Task (PAL), and Stockings of Cambridge items (SOC)]. The two groups were matched for symptom severity. ANOVA with repeated measures was employed to determine whether any difference in cognitive scores during a 2-year period was significantly related to the diagnostic status. RESULTS: A significant and durable difference was observed between SZ and SA on motor screening and explicit memory tests where SA performed better. CONCLUSION: Neurocognitive tests may be relevant for distinguishing schizoaffective from schizophrenia, chiefly via tests tapping into visuo-spatial and visuo-motor coordination abilities (e.g., paired associated learning and motor screening).     

Conflict of interest issues in informed consent for research on human subjects: a South Asian perspective

Health research for progress in the control and conquest of disease afflicting man is unquestionable. Concerns arise when motives other than the advancement of scientific knowledge and benefit for individuals and society are the driving force behind clinical trials. These conflicts of interests become even more pronounced when dealing with populations rendered vulnerable by virtue of poverty and ignorance. South Asia with its teeming millions represents one such region. This essay examines the reasons that make this population vulnerable to exploitation. Informed consent in the process of research is an area where such conflicts are prone to arise. In order to ensure that conflicting interests of researchers and funding agencies are kept in check, the processes of informed consent and ethical review of research need to be strengthened. Suggestions are put forward to modify the consent process to match the needs of South Asia and to strengthen the ethical review process for safeguarding the rights of the study subjects. But perhaps the most important safeguard against exploitation is the virtuous researcher himself with noble intentions. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

The greening of engineers: A cross-cultural experience

Experience with a group of mechanical engineering seniors at the University of Colorado led to an informal experiment with engineering students in India. An attempt was made to qualitatively gauge the students’ ability to appreciate a worldview different from the standard engineering worldview—that of a mechanical universe. Qualitative differences between organic and mechanical systems were used as a point of discussion. Both groups were found to exhibit distinct thought and behavior patterns which provide important clues for sensitizing engineers to environmental issues in future educational initiatives. Cross-cultural and global dimensions of these initiatives are discussed.     

Ways of coping and religious commitment in Muslim adolescents

The aim of this study was to find out methods of coping used most frequently by Kurdish adolescents and to investigate the relationship of methods of coping with their level of religiosity and gender. A convenience sample of 171 secondary school students, self-identified as Muslims, took part in answering two sets of questionnaires: methods of coping and religious commitment. Means, standard deviations, t-test and Pearson Correlation Coefficients were used to analyse the data. Results of the study suggest that the method of coping used most frequently by the sample was spiritual connection while passivity and avoidance were the least used methods of coping. Religiosity was correlated with all other methods of coping except seeking social support and passivity. Girls used avoidance and passivity for coping more than boys did. Kurdish Muslim adolescents use various methods to cope with problems they face. Counsellors in secondary schools should pay more attention to maladaptive methods of coping particularly among girl adolescents.     

Relationships of the Practice of Hijab,Workplace Discrimination,Social Class,Job Stress,and Job Satisfaction Among Muslim American Women

Religious discrimination in the workplace has received little attention in the research. The present study is an exploratory study that investigated the impact of workplace discrimination on a self‐selected sample of diverse Muslim women living across the United States (N = 129). The results of this study revealed that workplace discrimination, job stress, social class, and religiosity were related to lower levels of job satisfaction. Implications of the results are discussed in terms of clinical intervention strategies.     

Three Kinds of Social Kinds

Could some social kinds be natural kinds? In this paper, I argue that there are three kinds of social kinds: 1) social kinds whose existence does not depend on human beings having any beliefs or other propositional attitudes towards them (e.g. recession, racism); 2) social kinds whose existence depends in part on specific attitudes that human beings have towards them, though attitudes need not be manifested towards their particular instances (e.g. money, war); 3) social kinds whose existence and that of their instances depend in part on specific attitudes that human beings have towards them (e.g. permanent resident, prime minister). Although all three kinds of social kinds are mind‐dependent, this does not make them ontologically subjective or preclude them from being natural kinds. Rather, what prevents the third kind of social kinds from being natural kinds is that their properties are conventionally rather than causally linked.     

Function in context: Why American and Trinidadian young and older adults remember the personal past

Multiple and interacting contextual (culture, life phase) and person-specific predictors (i.e., personality, tendency to think-talk about the past) of the functions of autobiographical memory were examined using the Thinking about Life Experiences Scale. American (N = 174) and Trinidadian (N = 182) young and older adults self-reported how frequently they remembered the personal past to serve self, social and directive functions, how often they thought and talked about their past overall, and completed a measure of trait personality. Independent contextual and person-specific predictors were found for using memory to serve a social-bonding function: Americans, young adults, those higher in extraversion, lower in conscientiousness and individuals who frequently think and talk about the past more often use autobiographical memory for social bonding. Across cultures, younger adults report more frequently using memory to serve all three functions, whereas Trinidadians who think more often about the past compared with those who reflect less often are more likely to use it for self and directive functions. Findings are discussed in terms of the individual's embeddedness in cultural and life phase contexts when remembering.     

Relationships of Contextual Factors and Personal Identity to Externalizing Problem Behavior Among Iranian Early Adolescents

In the present study, we evaluated a model of relations among contextual factors (family, school, and peer group), personal identity (i.e., coherence and confusion), and problem behavior among Iranian adolescents. The sample consisted of 765 Iranian adolescents and 615 primary caregivers. Results indicated that family functioning (adolescent report) was related to adolescent problem behavior (a) directly and (b) indirectly through identity confusion. Peer support on the other hand was solely indirectly related to adolescent problem behavior through identity confusion. School functioning was also significantly and negatively related to adolescent problem behavior. The present findings suggest that identity and contextual factors play important roles in steering Iranian adolescents toward or away from behavior problems. Implications for further research are discussed.
