Constructing concepts without feedback: An empirical investigation of how relational information affects multidimensional concept completion behavior in an unsupervised task

The ability of humans to intentionally learn, without feedback, unidimensional stimulus relations in categorization tasks has been empirically established over the past two decades.  However, whether observers can learn more complex multidimensional stimulus relations across these unsupervised tasks has not yet been determined.  We demonstrate across an unsupervised concept completion experiment that the failure to observe multidimensional learning in previous experiments may be attributable to factors such as increased stimulus or task complexity.  We posit that concept completion is related to category learning in that it reveals the underlying tendencies that are associated with some categories being easier to learn than others.  In our experiments, we found observers readily learned to complete a two-dimensional exclusive-or concept, evidenced by an increase in object selection as the task progressed with a decrease in choice response times. We also found that ob..., , # Data from: Constructing concepts without feedback: An empirical investigation of how relational information affects multidimensional concept completion behavior in an unsupervised task

## Description of the data and file structure

This dataset contains the raw and processed data for the pilot experiment and the main experiment reported in Doan and Vigo (In Press, PLOS One), for assessing whether individuals display an increase in multidimensional concept completion behavior across trials of the concept completion task used by the authors.  Data cover six repeated-measures conditions of concept completions for the pilot experiment (1D-XOR-C3D, 1D-C3D-XOR, XOR-1D-C3D, XOR-C3D-1D, C3D-1D-XOR, C3D-XOR-1D) and two between-subjects conditions of concept completions for the main experiment (XOR-XOR, C3D-C3D).  For each experiment, we include data associated with the series of objects seen by participants (partial 1D, XOR, or ..., Participants provided written and verbal informed consent. Each participant was assigned a unique number, which was neither attached to nor stored with their name. There is no existing document that links the number with any participant's name, making it impossible to determine whose data belongs to any participant.
