Psychometric properties and measurement invariance of Depression,Anxiety and Stress Scales (DASS-21) across cultures

Cross-culturally measurement invariant instruments are useful for the assessment of mental symptoms across cultures. The current study aimed to investigate the psychometric properties and measurement invariance of the Depression, Anxiety and Stress Scales (DASS-21) (DASS) across Pakistan and Germany. German participants were recruited through an online survey (N = 1323), while Pakistani participants were recruited through online survey or paper-and-pencil survey (N = 1841). The DASS-21 showed good reliability, construct and structure validity in both countries. The DASS-21 indicated partial weak (stress subscale) and partial strong measurement invariance (depression and anxiety subscales) between both countries. Latent mean comparison of depression and anxiety symptoms between Pakistani and German students indicated that Pakistani university students experience more symptoms of depression and anxiety. Results suggest that the DASS-21 could be used in Pakistan and Germany, but caution should be taken when making direct comparisons between the two countries.     

The Bioterrorism Threat and Dual-use Biotechnological Research: An Israeli Perspective

Israel has a long history of concern with chemical and biological threats, since several hostile states in the Middle East are likely to possess such weapons. The Twin-Tower terrorist attacks and Anthrax envelope scares of 2001 were a watershed for public perceptions of the threat of unconventional terror in general and of biological terror in particular. New advances in biotechnology will only increase the ability of terrorists to exploit the burgeoning availability of related information to develop ever-more destructive bioweapons. Many areas of modern biological research are unavoidably dual-use by nature. They thus have a great potential for both help and harm; and facilitating the former while preventing the latter remains a serious challenge to researchers and governments alike. This article addresses how Israel might best (1) prevent hostile elements from obtaining, from Israel’s biological research system, materials, information and technologies that might facilitate their carrying out a biological attack, while (2) continuing to promote academic openness, excellence and other hallmarks of that system. This important and sensitive issue was assessed by a special national committee, and their recommendations are presented and discussed. One particularly innovative element is the restructuring and use of Israel’s extensive biosafety system to also address biosecurity goals, with minimal disruption or delay.     

Garner interference and temporal information processing

The aim of the study was to explore whether temporal information processing can interfere with performance of a non-temporal task. A new methodology based on the Garner paradigm was employed. Participants were asked to classify two-dimensional stimuli according to either length or duration, with and without variation in the other (task-irrelevant) dimension. Garner interference was detected only with respect to classification by length when irrelevant variation in duration was present. Stroop interference was detected only in classification by length across compatible and non-compatible values of length and duration. Classification by length took more time when done with variation in duration than when duration was constant. Classification by length also took more time when length and duration were not compatible than when they were compatible. The findings indicate that the processing of duration is similar to the processing of other perceptual dimensions. The processing of duration consumes attentional resources and can interfere with the processing of other perceptual dimensions. The findings support attentional models of prospective duration judgment.     

Consciousness and control in task switching

Participants were required to switch among randomly ordered tasks, and instructional cues were used to indicate which task to execute. In Experiments 1 and 2, the participants indicated their readiness for the task switch before they received the target stimulus; thus, each trial was associated with two primary dependent measures: (1) readiness time and (2) target reaction time. Slow readiness responses and instructions emphasizing high readiness were paradoxically accompanied by slow target reaction time. Moreover, the effect of task switching on readiness time was an order of magnitude smaller then the (objectively estimated) duration required for task preparation (Experiment 3). The results strongly suggest that participants have little conscious awareness of their preparedness and challenge commonly accepted assumptions concerning the role of consciousness in cognitive control.     

Mind–culture interactions: How writing molds mental fluidity in early development

This study investigated intellectual development in 4–7 years old Greek and Chinese children. They were examined on speeded performance, working memory, reasoning, and self-awareness tasks in order to investigate possible effects of learning the Chinese logographic system on possible differences in intellectual development between these ethnic groups. Speeded performance was examined with commonly familiar objects and tasks related to reading (i.e., Latin, Arabic, and Chinese characters). Chinese outperformed Greeks in (1) reading-related processing efficiency tasks but not in common objects (2) spatial but not verbal WM, (3) cognitive, and (4) the self-awareness tasks. Structural equation modeling showed that performance is organized in four systems (i.e., domain-specific problem solving, representational capacity, inference, and consciousness) integrated by g, in both ethnic groups. There were differences between the two ethnicities in the strength of relations between constructs, attributed to Chinese logographic experience. That is, the massive practice in visuo/spatial processing and memory seemed to provide an advantage in the communication between systems of the mind causing increased general cognitive fluidity, expressed in higher intellectual performance among the Chinese.     

Factorial invariance and latent mean differences of scores on trait emotional intelligence across gender and age

Little is known about the factorial invariance and latent mean difference across sex and age in trait emotional intelligence (EI). The purpose of this study was to examine whether the measurement structure underlying trait EI is equivalent across sex and age groups. The sample consisted of 2919 teenagers, youths and adults. In order to investigate the above hypothesis the measurement and structural equivalence as well as the equality of latent means of scores across sex and age were tested. The multi-group confirmatory factor analysis results revealed that configural, metric, scalar and structural invariance exist across sex and age samples. Findings regarding the latent mean differences across sex and age groups are discussed with reference to recent and past findings.     

The emerging self: the convergence of mind,personality and thinking styles

This paper aims to integrate research and theorizing about problem solving, self and personality into a comprehensive theory. With this purpose, the paper attempts to answer three questions: how do humans become aware of themselves and how do the products of self-awareness interrelate to produce an integrated self-system, which includes the domains of cognition and personality? How do persons know and influence each other? How do these processes change with development? The answers given to these questions by self, personality and cognitive developmental psychology are critically examined. It is concluded that an overarching model would have to assume a multilevel and multidimensional architecture. This would involve three main levels: the first includes general-purpose processes and functions, such as processing efficiency and working memory, which define current cognitive potentials; the second includes several domain-specific systems directed to different aspects of the environment; the third includes self-oriented processes that register, represent and regulate processes at the other two levels. Each person’s self-concepts result from the application of the third level on the other two and they differentially reflect their condition. Personality reflects the interaction between these self-concepts and dispositions to act in particular ways. Because humans share this architecture they can negotiate and affect each other’s self- and reflected representations. Thus, the formation of mind, self and personality results from a continuous flow of interactions between the levels and domains of mind within and across persons. The article summarizes a series of studies lending support to this general model.     

The changing dynamics of religious authority on Pakistani religious television

This paper analyses the production, ownership and control of Pakistani religious talk shows, which have emerged as a popular genre of religious programming, subsequent to the liberalisation of Pakistani media in 2002. Much scholarship has implicated the nexus between Islam and televisual media in enabling the fragmentation of religious authority, by altering ‘lay’ engagements with Islam and thereby eliciting wider participation in religious discourse. In contrast, this paper focuses on the changing terms of asserting religious authority in the newly liberalised media context. Based on an analysis of the innovative formats and modes of editorial control characterising contemporary religious shows, I posit the significance of religious talk shows in both altering the nature of scholarly participation in religious public debate, and subjecting featured scholars to non-scholarly interests and agendas. I argue that the latter two insights into the nature of religious authority on television are only accessible from a production-based perspective, which is crucial for evaluating the wider implications of broadcast media for religious authority.
