Orientation of crystals for HREM is done in diffraction mode. To do this efficiently thorough knowledge of the electron microscope and the reciprocal lattice of the investigated material is essential. With respect to the electron microscope extensive training is required to obtain the ability to tilt a crystal in the desired orientation. Familiarity with the reciprocal lattice of the investigated materials has to be obtained by tilt experiments on a relatively large number of crystals in the electron microscope. Even for experienced electron microscopists this can be very time consuming.In order to be able to practice tilt experiments without using the electron microscope, a program to simulate the electron microscope in diffraction mode was developed. The inexperienced electron microscopist may use the program to practice tilting of crystals. The experienced microscopist can use the program to familiarize with the reciprocal lattice of materials, which have not been studied by him before.

Grégoire, Perruchet, and Poulin-Charronnat (2013) claimed that the Musical Stroop task, which reveals the automaticity of note naming in musician experts, provides a new tool for studying the development of automatisms through extensive training in natural settings. Many of the criticisms presented in the four commentaries published in this issue appear to be based on a misunderstanding of our procedure, or questionable postulates. We maintain that the Musical Stroop Effect offers promising possibilities for further research on automaticity, with the main proviso that the current procedure makes it difficult to tease apart facilitation and interference.

The Impact

Although we live on the same planet, there are countless different ways of seeing the surroundings that reflect the different individual experiences and selective pressures. In recent decades, visual illusions have been used in behavioural research to compare the perception between different vertebrate species. The studies conducted so far have provided contradictory results, suggesting that the underlying perceptual mechanisms may differ across species. Besides the differentiation of the perceptual mechanisms, another explanation could be taken into account. Indeed, the different studies often used different methodologies that could have potentially introduced confounding factors. In fact, the possibility exists that the illusory perception is influenced by the different methodologies and the test design. Almost every study of this research field has been conducted in laboratories adopting two different methodological approaches: a spontaneous choice test or a training procedure. In the spontaneous choice test, a subject is presented with biologically relevant stimuli in an illusory context, whereas, in the training procedure, a subject has to undergo an extensive training during which neutral stimuli are associated with a biologically relevant reward. Here, we review the literature on this topic, highlighting both the relevance and the potential weaknesses of the different methodological approaches.

The Difference

Five experiments, all employing conditioned suppression in rats, studied inhibitory conditioning to a stimulus signalling a reduction in shock intensity. Experimental subjects were conditioned to a tone signalling a 1·0 mA shock and to a tone-light compound signalling a 0·4 mA shock. On a summation test in which it alleviated the suppression maintained by a third stimulus also associated with the 1·0 mA shock, the light was established as a conditioned inhibitor. Retardation tests gave ambiguous results: the light was relatively slow to condition when paired, either alone or in conjunction with another stimulus, with the 0·4 mA shock, but the difference from a novel stimulus control group was not significant. Two final experiments found no evidence at all of inhibition on a summation test in which the light was presented in conjunction with a stimulus that had itself been associated with the 0·4 mA shock. The results of these experiments have implications for the question of what animals learn during the course of inhibitory conditioning.

Healthcare Need

System performance in healthcare pivots on the ability to match demand for care with the resources that are needed to provide it. High reliability is desirable in organizations that perform inherently hazardous, highly technical tasks. However, healthcare's high variability, diversity, partition between workers and managers, and production pressure make it difficult to employ essential aspects of high reliability organizations (HROs) such as redundancy and extensive training. A different approach is needed to understand the nature of healthcare systems and their ability to perform and survive under duress; in other words, to be resilient. The recent evolution of resilience engineering affords the opportunity to configure healthcare systems so that they are adaptable and can foresee challenges that threaten their mission. Information technology (IT) in particular can enable healthcare, as a service sector, to adapt successfully, as long as it is based on cognitive systems engineering approaches to achieve resilient performance.

Pearson Correlations

32 male parolees and probationers were administered the questionnaire form of the Environmental Deprivation Scale followed by the standard oral interview for the purpose of comparing written responses with oral responses usually necessary to score the scale. Pearson correlations were .89 between written and oral responses and .97 for rater-rater agreement for scoring the questionnaire form. These results suggest that a reliable score for the scale can be obtained from an antisocial population without the extensive training and time required to administer behavioral interviews. Therefore, substituting group testing in place of one-on-one interviews may broaden the utility of the scale.
