Jena Voice Learning and Memory Test (JVLMT)

The JVLMT is a 22 min standardized voice memory test with a learning phase, a repetition phase and a testing phase. Participants learn 8 male and female voices by means of short utterances. At test, learned voices need to be selected among foils. Each test trial contains one target voice and two foils presented consecutively (3-AFC task). The testing phase includes 22 trials with varying difficulty (Rasch-conform), as achieved by various utterance durations and manipulations of acoustic similarity between voices. All stimuli contain pseudo speech utterances with similar-to-English phonetics, making the test applicable across a wide range of language backgrounds. Results of each participant will be displayed at the end of the test. Age and gender norms for adults are available and were obtained from a worldwide sample, participating in an online version of the test. The JVLMT is available as programmed in PsychoPy.

Terms of Use

The JVLMT has been developed and validated for research purposes between 2018 – 2020 by researchers of the Friedrich-Schiller University Jena, Germany and the RWTH University of Aachen. The test is free to use in a non-profit manner, without the need to register.

The original paper by Humble et al. (2023) must be cited whenever the JVLMT is used. It contains details on test construction and validation.
