Moving beyond the enduring dominance of positivism in psychological research: Implications for psychology in Australia

Almost since its inception, the dominant narrative of modern psychology has embraced positivism through its insistence that psychological science is objective, generalisable, and value free (or neutral). Consequently, quantitative research and, in particular, experimental designs, are privileged over other forms of enquiry, and other epistemologies, methodologies, and methods remain marginalised within the discipline. We argue that the enduring hegemony of positivism needs to be opposed to enable psychology to genuinely understand the antecedents of, and provide meaningful sustainable solutions for, complex human issues without being constrained by a narrow focus on method. We discuss the ways in which psychology in Australia can move towards embracing a constructionist epistemology that provides the framework for methodological pluralism. We provide a number of suggestions for change across the interrelated areas of accreditation, curriculum, the Australian Psychological Society, and research.     

The impact of surface projection on military tactics comprehension

This experiment assessed how displaying information onto different surfaces (flat vs. raised) influenced the performance, workload, and engagement of cadets answering questions on military tactics. Sixty-two cadets in a within-subjects design each answered 24 tactics-related questions across 2 conditions (12 on flat, 12 on raised) which were measured by accuracy and time on task. After each set of 12 questions, the cadets took postsurveys assessing engagement, measured by a modified User Engagement Scale and the System Usability Scale, and workload measured by the NASA-TLX. Findings indicated that raised terrain surface led to reduced workload and increased engagement and time on task as compared to the flat terrain surface. A practice effect drove performance metrics (time on task and accuracy), where the learner performed better on the second surface type displayed. This research contributes to expanding the literature base that supports alternative display methods to increase engagement and augment instruction of military tactics tasks.     

大力促进心理学的理论研究

虽然心理学作为一门独立的学科已有100多年的历史,但是心理学一直缺乏带有“范式”特点的心理学理论。这导致了心理学的破碎和分裂。探讨心理学的“元”理论,大力促进心理学的理论研究,是心理学发展的当务之急。     

Belief Revision,Rational Choice and the Unity of Reason

Hans Rott has argued, most recently in his book Change, Choice and Inference, that certain formal correspondences between belief revision and rational choice have important philosophical implications, claiming that the former strongly indicate the unity of practical and theoretical reason as well as the primacy of practical reason. In this paper, I confront Rott's argument with three serious challenges. My conclusion is that, while Rott's work is indisputable as a formal achievement, the philosophical consequences he wants to draw are not forthcoming. This revised version was published online in August 2006 with corrections to the Cover Date.

The illuminative function of the agent intellect

Thomas Aquinas argues that the agent intellect's function is to abstract an intelligible species from a phantasm. However, insofar as he claims that the intelligible species is not present in the phantasm, it is unclear how the agent intellect accomplishes this task. In this paper I explore two models of abstraction – the extraction model and the production model – suggesting that each fails to capture Aquinas’ understanding of abstraction. I then offer my own interpretation of the function of the agent intellect – the illumination model – by employing Aquinas’ comparison of the agent intellect to light. I argue that the agent intellect neither extracts nor produces an intelligible species, but rather makes the nature that is already present in the object intelligible by actualizing its passive power of intelligibility. This involves the co-actualization of partner powers in the intellect and in the intelligible object, and ultimately makes it possible to cognize a particular, material object in a universal way.     

Disability and disasters: the role of self-efficacy in emergency preparedness

Although individuals with physical disabilities have special needs regarding preparedness for a natural or human-made disaster, little is known about the factors involved in motivating members of this population to engage in behaviors which reduce the probability of negative health outcomes. This study proposes and empirically tests an integrated theory-based model for individuals with physical disabilities in which perceived self-efficacy for emergency preparedness moderates the relationship between perceived threat and emergency preparedness behaviors. A nationwide convenience cross-sectional sample of 294 adults self-identifying as having a physical disability completed an online survey. The general linear model was used to assess the effects on preparedness of perceived threat, perceived self-efficacy, and their interaction. In addition to the hypothesized moderating effect of self-efficacy, it was found that minimal (if any) relationship exists between perceived threat and preparedness among those who reported low levels of self-efficacy. Results suggest that self-efficacy and perceived threat operate jointly to motivate individuals with physical disabilities to take precautionary steps to reduce the consequential adverse health effects of natural and human-made disasters. These findings have important implications for the design of effective interventions for individuals with disabilities.

Chinese Marxist Philosophy Since Reform and Opening-Up

Since reform and opening-up began in 1978, Chinese Marxist philosophy has undertaken the double mission of enhancing the emancipation of the mind in society and of realizing its own ideological emancipation. It has gone through an evolutionary process from “extensive discussion about the criterion of truth” to “reform of philosophical textbooks”; from the proposal of the philosophical conception of “practical materialism” to reflection on “modernity”; and from the carrying-out of dialogues among Chinese, Western, and Marxist philosophies to the exploration of “new forms of civilization.” Chinese Marxist philosophy has shifted its way of doing research with practical materialism as a core conception, and it changed such modes of thinking as the intuitive theory of reflection based on na?ve realism, the theory of linear causality based on mechanical determinism, and the reductionism of essence based on abstract substantialism. As a result, it has boosted changes that were already underway in Chinese philosophy, worldviews, theories of truth, conceptions of history, and views of development, and it has further endowed the discourse system of Marxist philosophy with laudable subjectivity and originality.     

Measurement of functional task difficulty during motor learning: What level of difficulty corresponds to the optimal challenge point?

The relationship between task difficulty and learning benefit was examined, as was the measurability of task difficulty. Participants were required to learn a postural control task on an unstable surface at one of four different task difficulty levels. Results from the retention test showed an inverted-U relationship between task difficulty during acquisition and motor learning. The second-highest level of task difficulty was the most effective for motor learning, while learning was delayed at the most and least difficult levels. Additionally, the results indicate that salivary α-amylase and the performance dimension of the National Aeronautics and Space Administration-Task Load Index (NASA-TLX) are useful indices of task difficulty. Our findings suggested that instructors may be able to adjust task difficulty based on salivary α-amylase and the performance dimension of the NASA-TLX to enhance learning.
