Heuristic thinking and human intelligence: a commentary on Marewski,Gaissmaier and Gigerenzer

Marewski, Gaissmaier and Gigerenzer (2009) present a review of research on fast and frugal heuristics, arguing that complex problems are best solved by simple heuristics, rather than the application of knowledge and logical reasoning. We argue that the case for such heuristics is overrated. First, we point out that heuristics can often lead to biases as well as effective responding. Second, we show that the application of logical reasoning can be both necessary and relatively simple. Finally, we argue that the evidence for a logical reasoning system that co-exists with simpler heuristic forms of thinking is overwhelming. Not only is it implausible a priori that we would have evolved such a system that is of no use to us, but extensive evidence from the literature on dual processing in reasoning and judgement shows that many problems can only be solved when this form of reasoning is used to inhibit and override heuristic thinking.     

MouseTracker: Software for studying real-time mental processing using a computer mouse-tracking method

In the present article, we present a software package, MouseTracker, that allows researchers to use a computer mouse-tracking method for assessing real-time processing in psychological tasks. By recording the streaming x-, y-coordinates of the computer mouse while participants move the mouse into one of multiple response alternatives, motor dynamics of the hand can reveal the time course of mental processes. MouseTracker provides researchers with fine-grained information about the real-time evolution of participant responses by sampling 60–75 times/sec the online competition between multiple response alternatives. MouseTracker allows researchers to develop and run experiments and subsequently analyze mouse trajectories in a user-interactive, graphics-based environment. Experiments may incorporate images, letter strings, and sounds. Mouse trajectories can be processed, averaged, visualized, and explored, and measures of spatial attraction/curvature, complexity, velocity, and acceleration can be computed. We describe the software and the method, and we provide details on mouse trajectory analysis. We validate the software by demonstrating the accuracy and reliability of its trajectory and reaction time data. The latest version of MouseTracker is freely available at http://mousetracker.jbfreeman.net.     

Hope and positive religious coping as predictors of social justice commitment

The present study tested a theoretical model of dispositional hope and positive religious coping as unique predictors of social justice commitment over and above impression management in a sample of graduate students (N?=?214) in helping professions at an Evangelical Protestant university in the USA. This empirical study utilised a cultural psychology approach with a theoretical framework developed from (a) an earlier cultural psychology study of hope and social justice using the social philosophies of Martin Luther King, Jr, Cornel West, and Paulo Freire and (b) several liberation and Pietistic theologians. Results supported the discriminant validity hypothesis with dispositional hope and positive religious coping each predicting social justice commitment over and above a measure of spiritual impression management. Implications are considered for contextually sensitive training and future empirical and interdisciplinary research on social justice commitment.     

Cohen’s Conservatism and Human Enhancement

In an intriguing essay, G. A. Cohen has defended a conservative bias in favour of existing value. In this paper, we consider whether Cohen’s conservatism raises a new challenge to the use of human enhancement technologies. We develop some of Cohen’s suggestive remarks into a new line of argument against human enhancement that, we believe, is in several ways superior to existing objections. However, we shall argue that on closer inspection, Cohen’s conservatism fails to offer grounds for a strong sweeping objection to enhancement, and may even offer positive support for forms of enhancement that preserve valuable features of human beings. Nevertheless, we concede that Cohen’s arguments may suggest some plausible and important constraints on the modality of legitimate and desirable enhancements.     

Working with prisoners in a transitional space

In this paper I talk about the potential benefits for offenders of working within the transitional space provided by a discussion group. Through ‘play’ these men have an opportunity to interact and learn to be potent without resorting to omnipotent defences of violence to get their own way. In considering the discussion group within the context of the prison as a whole, I focus on the relationship between staff and prisoners and how this relationship can be managed in such a way as to create more opportunities for thinking, leading to an enhanced focus on rehabilitation.     

Saboteur and superego: The judgement of the ego in brief dynamic therapy

Drawing principally upon the work of Woodmansey the author describes the development of the punitive or humiliating superego as arising from the internalisation of an external conflict, which the child experiences with adult carers, and from whom the child fears retaliatory punishment or scornful reproach. The superego serves the function of extricating the child from the external conflict. Woodmansey’s view of the natural instincts and the development of a moral sense are compared to those of Winnicott, Fairbairn and Guntrip. The notion of a pristine unitary ego and the development of an internal saboteur arising from the frustration of needs for relatedness are outlined and linked conceptually to the development of the punitive superego. The role and judgement of the ego and its emancipation from the superego in accordance with Britton’s formulation are highlighted and related to clinical practice and the alternating transference. These clinical themes are discussed in relation to eliciting affects and narrative construction and deconstruction in brief dynamic work and illustrated by a case example.     

Slouching Toward Policy: Lazy Bioethics and the Perils of Science Fiction

Too much contemporary bioethical discourse is weak on science, lazily citing and adopting science fiction scenarios rather than science facts in the framing of analyses and policies. We challenge bioethicists to take more seriously the role of providing informed insight into and oversight over contemporary science and its implications and applications. Bioethicists must work harder to understand the fast-changing truths and limits of basic science, and they must incorporate only appropriate and authentic science into their discourse, just as they did in the past when addressing the quandaries of clinical medicine. The field of bioethics is not so old and entrenched that its future is assured. Bioethicists must make themselves useful to society in order to deserve and retain the public's trust. They can best do this by ensuring that decision making and public policy are grounded in facts, not fictions and fantasies.
