Editorial

It is a pleasure to announce the double issue in 2023 as published. This issue contains 10 articles, and four of the articles are published in a special section (see below). The first article by Colasurdo, K. F. Reeve, Jennings, Vladescu, Albright, and S. A. Reeve established conditional discriminations using compound stimuli as both samples and comparison and compared this training with the typical presentation of stimuli when establishing conditional discrimination. The aim of the second article by Staropoli, Colasurdo, K. F. Reeve, S. A. Reeve, and Deshais was to compare the effect of repeating and not repeating a trial in conditional discrimination training for the emergence of equivalence classes. The third article Ban and McGill is a systematic review of publications between 1982 and 2022 on conditioned motivating operations in mand training for children with autism spectrum disorder. The fourth article by Lee, Kan, Luke, and Lin explored the effects of different instruction sequences, combined listener instruction and combined speaker instruction on learning Mandarin-Chinese vocabulary. The fifth article by T. Taylor and S. A. Taylor included a review of articles published from 2009 to 2020 on treatment processes and outcomes for paediatric feeding disorders. A delayed matching-to-sample procedure used in the sixth article by Ratkos, Camacho, and O’Dell included distractors in the delay in nine typically developing children.

Special section

Professor Zuilma Gabríela Sigurðardóttir served as the Guest Editor for the special section based on papers presented at the EABA conference in Tampere, Finland. The conference was held in June 2022. All submitted manuscripts underwent the ordinary reviewing process, and four articles are published in this issue. The first article by Kingsdorf and Pancocha presents data on the growth of applied behavior analysis in the Czech Republic since 2016. Zayac, Van Stratton, and Paulk in the second article explored the potential qualities and corresponding behaviors that contribute to effective behavior analytic service delivery and how it may assist practitioners in strengthening their behavioral repertoire. Braaten and Arntzen in the third article used different stimulus sets in training conditional discrimination and formation of stimulus equivalence, and how different stimulus sets affected eye movements. The fourth article in this issue is by Steingrimsdottir, Vilhjálsmdóttir, and Arntzen. They studied the effect of the differential outcome procedure’s effect on establishing baseline conditional discriminations. EJOBA is very grateful to Professor Sigurðardóttir for all her work on the manuscripts submitted to this special section.
