In the 1970s there was considerable interest in the development of the electron channelling contrast imaging (ECCI) technique for imaging near surface defects in bulk (electron opaque) specimens. The predictions of the theories were realised experimentally by Morin et al., who used a field emission gun (FEG) operating at 40-50kV and an energy filter such that only electrons which had lost no more than a few 100V were detected. This paper presents the results of a set of preliminary experiments which show that an energy filter system is unneccessary to image and characterise the Burgers vectors of dislocations in bulk specimens. The examples in the paper indicatethe general versatility of the technique.A VG HB501 STEM with a FEG was operated at 100kV. A single tilt cartridge was used in the reflection position of the microscope. A retractable back-scattered electron detector was fitted into the secondary electron port and positioned to within a few millimetres of the specimen. The image was acquired using a Synoptics Synergy framestore and digital scan generator and subsequently processed using Semper 6. The beam divergence with the specimen in this position was 2.5 mrads with a spot size of approximately 4nm. Electron channelling patterns were used to orientate the sample.

Abstract. This project compared the relative performance of professional dancers and nondancers on the Music Apperception Test (MAT; van den Daele, 2014 ), then compared dancers’ performance on the MAT with that on the Thematic Apperception Test (TAT; Murray, 1943 ). The MAT asks respondents to “tell a story to the music” in compositions written to represent basic emotions. Dancers had significantly shorter response latency and were more fluent in storytelling than a comparison group matched for gender and age. Criterion-based evaluation of dancers’ narratives found narrative emotion consistent with music written to portray the emotion, with the majority integrating movement, sensation, and imagery. Approximately half the dancers were significantly more fluent on the MAT than the TAT, while the other half were significantly more fluent on the TAT than the MAT. Dancers who were more fluent on the MAT had a higher proportion of narratives that integrated movement and imagery compared with those more fluent on the TAT. The results were interpreted as consistent with differences observed in neurological studies of auditory and visual processing, educational studies of modality preference, and the cognitive style literature. The MAT provides an assessment tool to complement visually based performance tests in personality appraisal.
