Rats (Rattus Norvegicus) Flexibly Retrieve Objects’ Non-Spatial And Spatial Information From Their Visuospatial Working Memory: Effects Of Integrated And Separate Processing Of These Features In A Missing-Object Recognition Task, Corrine Nicole Keshen, Jerome Cohen

Psychology Publications

After being trained to find a previous missing object within an array of four different objects, rats received occasional probe trials with such test arrays rotated from that of their respective three-object study arrays. Only animals exposed to each object’s non-spatial features consistently paired with both its spatial features (feeder’s relative orientation and direction) in the first experiment or with only feeder’s relative orientation in the second experiment (Fixed Configuration groups) were adversely affected by probe trial test array rotations. This effect, however, was less persistent for this group in the second experiment but re-emerged when objects’ nonspatial features were …
