| dc.description.abstract | The first article is a systematic summarizing review of research on nodal number effects within the field of stimulus equivalence. The starting point of the review is a previous summarizing article by Fields and Moss (2007). This present review summarizes how experimental findings have further elaborated on the nodal effects in stimulus equivalence research results. The method of data collection is systematic searches of databases and electronic scientific journals. A total of 12 articles have been included in the review as a result of the search. Articles are selected through set criteria and a set of relevant datapoints are collected from each experiment. After presenting each article, the results of the review are summarized and discussed in relation to previous research and possible future research is suggested.
The second article is based on experimental research in the field of stimulus equivalence. The experiment had 20 participants, where the results of the 14 participants that completed training and testing are included in the results of the experiment. The experiment is focusing on how alternations in presentation order of relations, and the number of times a relation is presented, affects the outcome of the equivalence test in terms of equivalence class formation, correct responding sorted by nodal number in emergent relations, reaction time sorted by nodal number in relations, and within class preference tests. The results are listed, showcased in tables and diagrams, and elaborated on. Finally, the results are summarized and relations to previous and possible future research discussed. | en_US |
