Test materials for the Adaptive Melodic Discrimination Test
<pre>This repository contains stimuli and psychometric data for the adaptive melodic discrimination test constructed in Harrison et al. (2017). These materials can be used to construct a computerised adaptive melodic discrimination test. An implementation of the test is available from the authors upon request. This version (v5) corresponds to the final version of the test constructed in Harrison et al. (2017); it includes the easier items added to the item bank in Study 3. It also contains a corrected melodic_discrimination_psych_data.csv file; the previous version was incomplete. These test materials may be freely used for research purposes. Please cite Harrison et al. (2017) in any publications using these materials (see below for full citation info). ==Reference== Harrison, P. M. C., Collins, T., & Müllensiefen, D. (2017).

Data from: Acorn woodpeckers vocally discriminate current and former group members from non-group members
<p>In species with long-term social relationships, the ability to recognize individuals after extended separation, and the ability to discriminate between former social affiliates that have died and those that have left the group but may return, are likely to be beneficial. Few studies, however, have investigated whether animals can make these discriminations. We presented acorn woodpeckers (Melanerpes formicivorus), a group-living, cooperatively breeding bird, with playbacks of current group members, former group members still living nearby, former group members that had died or left the study area, and familiar non-group members. Subjects responded more quickly to the calls of non-group members than to the calls of current group members or former group members still living in the study area but did not discriminate between non-group members and former group members that had died or disappeared. This suggests that acorn woodpeckers can vocally recognize both current group members and former group members that have dispersed to nearby groups, and that they either forget former group members that no longer live in the vicinity, or classify them differently from former group members that still live nearby. This study suggests an important role for vocal recognition in maintaining valuable relationships with social affiliates post-dispersal.</p>
Fruit flies can learn non-elemental olfactory discriminations
Associative learning allows animals to establish links between stimuli based on their concomitance. In the case of Pavlovian conditioning, a single stimulus A (the conditional stimulus, CS) is reinforced unambiguously with an unconditional stimulus (US) eliciting an innate response. This conditioning constitutes an 'elemental' association enabling to elicit a learnt response from A+ without US presentation after learning. However, associative learning may involve a 'complex' CS composed of several components. In that case, the compound may predict a different outcome than the components taken separately, leading to an ambiguity and requiring the animal to perform a so-called 'non-elemental' discrimination. Here we focus on such a non-elemental task, the negative patterning (NP) problem, and provide the first evidence of NP solving in Drosophila. We show that Drosophila learn to discriminate a simple component (A or B) associated to electric shocks (+) from an odour mixture composed either partly (called 'feature-negative discrimination' A+ vs. AB-) or entirely (called 'NP' A+B+ vs. AB-) of the shock associated components. Furthermore, we show that conditioning repetition results in a transition from an elemental to a configural representation of the mixture required to solve the NP task, highlighting the cognitive flexibility of Drosophila.
