    Rats trained to remember arm choices in a maze showed different memory patterns. Win-stay training resulted in U-shaped memory curves, while win-shift training only showed recency effects.

    Area of Science:

    • Cognitive Psychology
    • Animal Behavior

    Background:

    • The Olton eight-arm radial maze is a standard tool for studying spatial memory in rodents.
    • Serial position curves (SPCs) reveal how memory recall varies based on an item's position in a list.

    Purpose of the Study:

    • To compare the memory recall patterns (SPCs) generated by win-stay and win-shift training procedures in rats.
    • To investigate the differential processing demands of win-stay versus win-shift rules on memory.

    Main Methods:

    • Rats were trained on an eight-arm radial maze using a forced-choice recognition test.
    • Two groups were formed: 10 rats trained on a win-stay rule and 10 on a win-shift rule.
    • Serial position curves were analyzed for both groups.

    Main Results:

    Related Experiment Videos

    • Win-stay trained rats exhibited a classical U-shaped SPC, demonstrating significant primacy and recency effects.
    • Win-shift trained rats displayed only recency effects in their SPCs.
    • A direct comparison revealed distinct memory processing strategies between the two groups.

    Conclusions:

    • The win-stay procedure appears to necessitate more effortful, elaborative memory processing.
    • The win-shift procedure is likely processed more automatically, leading to diminished primacy effects.
    • Differential processing requirements explain the observed differences in serial position curves.
