For memory retrieval, pattern completion is a crucial process that restores memories from partial or degraded cues. Neurocognitive aging models suggest that the aged memory system is biased toward pattern completion, resulting in a behavioral preference for retrieval over encoding of memories. The Memory Image Completion task (MIC) is a behavioral recognition memory task that specifically targets pattern completion and provides a means to assess related deficits or response biases. The task is provided as a Unity executable. It is easily, repeatedly and reliably testable. Please consult the following papers for details and cite them when using the MIC. If you have questions or run into problems executing the task, do not hesitate to contact paula.vieweg@uni-leipzig.de.
