Representational shifts made visible: movement away from the prototype in memory for hue
نویسندگان
چکیده
In four experiments, a total of 205 participants studied individual color patches and were given an old-new recognition test after a brief retention interval (0.5 or 5.0 s). The pattern of hue sensitivity (d') revealed hue memory shifting away from the prototype of the hue's basic color category. The shifts demonstrate that hue memory is influenced by categorization early in processing. The shifts did not depend on intentional categorization; the shifts were found even when participants made preference ratings at encoding rather than labeling judgments. Overall, we found that categorization and memory are deeply intertwined from perception onward. We discuss the impact of the results on theories of memory and categorization, including the effects of category labels on memory (e.g., Lupyan, 2008). We also put forward the hypothesis that atypical shifts in hue are related to atypical shifts that have previously observed in face recognition (Rhodes et al., 1987).

Representational Shifts Towards the Prototype in Memory for Hue
Representational shifts in memory have been a recent topic of interest and debate (Blanco & Gureckis 2012; Lupyan, 2008; Richler, Gauthier & Palmeri, 2011; Richler, Palmeri & Gauthier, 2012). Whether there are true systematic biases in memory due to a stimulus being labeled has been proposed and contested. The fundamental proposal that representations shift toward the prototype has not previous...

In this paper the design of a biped robot actuated with Shape Memory Alloy (SMA) springs with minimum degrees of freedom is presented. SMA springs are a class of smart materials that are known for their high power to mass and volume ratios. It was shown that utilizing spring type of SMAs have many advantages as large deformation, smooth motion, silent and clean movement compared to ordinary typ...

The human prefrontal cortex differs from all other mammals: the seat of complex cognition, abstract thinking, planning and future forecasting, and behavioral inhibition. Using our prefrontal cortex is a significant energy drain on the body, so despite its impressive capabilities, it’s daily capacity is limited. Some researchers estimate a mere 2-3 hours per day of activity depletes the pr...

While it is generally agreed that perception can occur without awareness, there continues to be debate about the type of representational content that is accessible when awareness is minimized or eliminated. Most investigations that have addressed this issue evaluate access to well-learned representations. Far fewer studies have evaluated whether or not associations encountered just once prior ...
