Tuning the field trip: audio-guided tours as a replacement for 1-day excursions in human geography

2013

Educators are experiencing difficulties with 1-day field trips in human geography. Instead of teaching students how to apply theory in the field and learn to sense geography in everyday life, many excursions have degraded into tourist-like events where lecturers try to motivate rather passive students against a noisy urban backdrop. Although various (partly) student-led approaches have successfully addressed the issue, there are still a high number of tours that use a traditional, tutor-led model. The example of a series of three audio tours produced at Johannes Gutenberg-University Mainz, Germany, shows how these conventional field trips can be transformed into audio tours that help studen…

Deviance sensitivity in the auditory cortex of freely moving rats.

2018

Deviance sensitivity is the specific response to a surprising stimulus, one that violates expectations set by the past stimulation stream. In audition, deviance sensitivity is often conflated with stimulus-specific adaptation (SSA), the decrease in responses to a common stimulus that only partially generalizes to other, rare stimuli. SSA is usually measured using oddball sequences, where a common (standard) tone and a rare (deviant) tone are randomly intermixed. However, the larger responses to a tone when deviant does not necessarily represent deviance sensitivity. Deviance sensitivity is commonly tested using a control sequence in which many different tones serve as the standard, eliminat…
