The potential utility of problem-based learning in the education of clinical psychologists and others.

Clinical psychologists, like most health professionals, are in essence clinical problem-solvers. However, dealing with mental health problems may necessitate a greater relative reliance upon inductive clinical reasoning during the problem-solving process. To develop a provisional problem formulation mental health professionals may have to make sense of the co-occurrence of complex and poorly delineated problems. Claims have been made, predominantly in the literature on medical education, regarding the utility of problem-based learning (PBL) for achieving aims central to the effective performance of this role. In this article, after characterizing clinical psychology and PBL, we briefly explore the benefits claimed for PBL and assert that the putative cognitive and interpersonal consequences of the approach may be particularly pertinent to mental health practice. Particular emphasis is placed upon the necessity of facilitating effective clinical reasoning, that is, teaching future practitioners how to, rather than what to, think about complex psychopathology. PBL is also considered in the wider context of models of experiential learning and methods for teaching problem-solving. Finally, future research questions are suggested which may provide answers relevant to the facilitation of effective clinical reasoning in all health professions.

Face detection in peripheral vision: do faces pop out?

We examined whether faces can produce a 'pop-out' effect in visual search tasks. In the first experiment, subjects' eye movements and search latencies were measured while they viewed a display containing a target face amidst distractors. Targets were upright or inverted faces presented with seven others of the opposite polarity as an 'around-the-clock' display. Face images were either photographic or 'feature only', with the outline removed. Naive subjects were poor at locating an upright face from an array of inverted faces, but performance improved with practice. In the second experiment, we investigated systematically how training improved performance. Prior to testing, subjects were practised on locating either upright or inverted faces. All subjects benefited from training. Subjects practised on upright faces were faster and more accurate at locating upright target faces than inverted. Subjects practised on inverted faces showed no difference between upright and inverted targets. In the third experiment, faces with 'jumbled' features were used as distractors, and this resulted in the same pattern of findings. We conclude that there is no direct rapid 'pop-out' effect for faces. However, the findings demonstrate that, in peripheral vision, upright faces show a processing advantage over inverted faces.
