Figure 1

Effect of varying the interfood interval on timed food anticipation in rats. Food was delivered at a fixed time after the previous food presentation. The time between food presentations was varied across different groups of rats. The figure shows responses per minute (head pokes into the food receptacle) as a function of time since the last food delivery. A burst of head poking that occurred after pellet delivery has been omitted from this replot of the data. Modified from Kirkpatrick and Church (2003) with permission.
