The Relationship between Reaction Time and Psychometric Intelligence in a Rural Guatemalan Adolescent Population

In industrialized countries reaction time has been found to be related to measures of intelligence and cognitive abilities. Little, however, is known about the validity of using such tasks in nonindustrialized countries. The present research investigated the association between reaction time and psychometric intelligence in a rural Guatemalan adolescent population. Results indicated that speed and consistency of processing on reaction time tasks were related to psychometric intelligence. However, the magnitude of these relationships were considerably smaller than those reported in industrialized populations. Reaction time task performance accounted for less than 5% of the variance in psychometric intelligence. Findings suggest that although reaction time tasks are associated with intelligence, the predictive validity of such measures needs to be established before use in nontraditional populations.     

The Future Models of Arab Political Economy

Three distinct models of political economy are articulated in this article to chart out the possible politico-economic futures of the Arab World. Of these, the present predicaments of the revolutionizing Arab populace are argued to have been caused by the continuance of the wrong social choices. It depended for a long time now on the alienating model of differentiation and alienation of the Arab nations by their rulers, and by their uncritical immersing in the equally debilitating globalization agenda. Two models of the alienating and unfeasible types are formulated as the prevailing ones today. The arguments and empirical study of limited socioeconomic data with the examples of Egypt, Tunisia and Yemen, which are considered as exemplary of the revolutionary Arab World, point out that social factors based on the demand for participation and representation, self-reliant social change, and opportunities are the overwhelming factors of politico-economic change. These factors, as opposed to the purely economic factors, must be embedded in a synergistic way with the rest in a distinctive future model of Arab political economy. Three formal models of possible political economy of the future Arab World with their evolutionary futures are formalized. Necessary social and policy implications are drawn in reference to these three evolutionary Arab futures in political economy.     

An Evolutionary Topological Theory of Participatory Socioeconomic Development

The epistemological foundation of unity of knowledge is used to formulate a system-model of participatory socioeconomic development. The micro-properties of such a participatory development approach are deeply ethical in nature. In order to bring out the endogenous role of ethics derived from the moral law in reference to the epistemic foundation, and thereby explain their impact on the socioeconomic development experience, the methods of topological space and topological mappings are found to be appropriate for formalizing the complex nature of participatory dynamics. They emerge in the midst of institutional and organic interaction, integration, and evolution. The application of topological methods to participatory socioeconomic development thus opens up a field that is rarely used by mathematical economists. In this sense this article is an original contribution to the area of ethical development theory and its topological explanation and application.     

Infant information processing and family history of specific language impairment: converging evidence for RAP deficits from two paradigms

An infant's ability to process auditory signals presented in rapid succession (i.e. rapid auditory processing abilities [RAP]) has been shown to predict differences in language outcomes in toddlers and preschool children. Early deficits in RAP abilities may serve as a behavioral marker for language-based learning disabilities. The purpose of this study is to determine if performance on infant information processing measures designed to tap RAP and global processing skills differ as a function of family history of specific language impairment (SLI) and/or the particular demand characteristics of the paradigm used. Seventeen 6- to 9-month-old infants from families with a history of specific language impairment (FH+) and 29 control infants (FH-) participated in this study. Infants' performance on two different RAP paradigms (head-turn procedure [HT] and auditory-visual habituation/recognition memory [AVH/RM]) and on a global processing task (visual habituation/recognition memory [VH/RM]) was assessed at 6 and 9 months. Toddler language and cognitive skills were evaluated at 12 and 16 months. A number of significant group differences were seen: FH+ infants showed significantly poorer discrimination of fast rate stimuli on both RAP tasks, took longer to habituate on both habituation/recognition memory measures, and had lower novelty preference scores on the visual habituation/recognition memory task. Infants' performance on the two RAP measures provided independent but converging contributions to outcome. Thus, different mechanisms appear to underlie performance on operantly conditioned tasks as compared to habituation/recognition memory paradigms. Further, infant RAP processing abilities predicted to 12- and 16-month language scores above and beyond family history of SLI. The results of this study provide additional support for the validity of infant RAP abilities as a behavioral marker for later language outcome. Finally, this is the first study to use a battery of infant tasks to demonstrate multi-modal processing deficits in infants at risk for SLI.     

Well-being, Happiness and Why Relationships Matter: Evidence from Bangladesh

Although Bangladesh is known as one of the poorest and most densely populated countries in the world, qualitative research and anecdotal evidence suggests its people report levels of happiness that are higher than those found in many other countries. This includes ‘developed’ countries where people have larger per capita incomes and can access a wider range of public services and goods. The paper explores this apparent paradox by analysing primary quantitative and qualitative data, and engaging with existing literature on happiness and objective wellbeing in Bangladesh. The data and analysis presented makes an original and timely contribution to the limited knowledge we have of the construction and experience of happiness and life satisfaction in contexts of extreme and persistent economic poverty. It identifies and offers insights into the ‘personal’ as well as social or ‘relational’ values and goals that people in Bangladesh consider important to achieve happiness in life. It also reflects on how different people experience these values and goals in very different ways. This, we argue, leads to a better understanding of the influence of the social and cultural context in the construction of people’s happiness. In the conclusion, we reflect on the policy implications of our findings.

Global megatrends and the community

An examination of the thesis of Asian megatrends as conceived of in the literature until recent times, is reviewed. Major ramifications within it, such as the role of Asian values, economic growth and development, a self‐reliant nationalism different from the West, and the rise of a human development concept, are critically examined. Yet the role of community as substantively defined in this paper, is found to have remained ignored in the study of major megatrends between the West and the East. This remiss in the study of human futures within a politico‐economic developmental context is argued to cause unsustainability of the megatrends paradigm. The projected decline of the Asian megatrends is shown to arise from its absence of an understanding of a ‘globally’ interactive, integrative and evolutionary process of understanding historical change. Within this new paradigm the epistemology of community is shown to play a much more substantive role than simply the pursuit of growth and development in the midst of capitalist globalism. Substantive methodological implications are shown to emanate from such a different view of studying megatrends in general. The concept of objective globalization is thereby derived.     

A social identity model of riot diffusion: From injustice to empowerment in the 2011 London riots

Previous research has shown that riots spread across multiple locations, but has not explained underlying psychological processes. We examined rioting in three locations during the August 2011 disorders in England to test a social identity model of riot diffusion. We triangulated multiple sources to construct a narrative of events; and we analysed interviews with 68 participants to examine experiences. In line with the model, we found evidence for two pathways of influence: “cognitive” and “strategic”. For some participants, previous rioting was highly self-relevant, and shared identity was the basis of their subsequent involvement. For others, previous rioting was empowering because it demonstrated the vulnerability of a common enemy (the police). In each location, interaction dynamics mediated the link between initial perceptions and collective action. The utility of this social identity approach is that it is able to account for both the boundaries and the sequence of urban riot diffusion.     

The evolving normative dimensions of ‘riot’: Towards an elaborated social identity explanation

The question of how normative form changes during a riot, and thus how collective behaviour spreads to different targets and locations, has been neglected in previous research, despite its theoretical and practical importance. We begin to address this limitation through a detailed analysis of the rioting in the London borough of Haringey in 2011. A triangulated analysis of multiple sources of data (including police reports, media accounts, and videos) finds a pattern of behaviour shifting from collective attacks on police targets to looting. A thematic analysis of 41 interview accounts with participants gathered shortly after the events suggests that a shared anti‐police identity allowed local postcode rivalries to be overcome, forming the basis of empowered action not only against the police but to address more long‐standing grievances and desires. It is argued that collective psychological empowerment operated in a ‘positive feedback loop’, whereby one form of collective self‐objectification (and perceived inability of police to respond) formed the basis of further action. This analysis of the development of new targets in an empowered crowd both confirms and extends the elaborated social identity model as an explanation for conflictual intergroup dynamics.
