II. Spatial Memory in Food Caching & II. Spatial Memory in Food Caching & Recovery Recovery Ruling out non-memory interpretations: Kamil & Balda (1985), Fig 12.1 Nutcrackers in room w/ 180 recessed cups of sand, some 3 sessions to store seeds; only 18 cups available ea session 4 recovery sessions 10 days after caching Findings: Based on Fig 12.1

II. Episodic Memory in Food Caching II. Episodic Memory in Food Caching Establishing non-phenomenological features of episodic memory in nonhuman animals: Clayton et al (2003) Figs. 12.2-4 (what, where, when info integrated) Scrub jays prefer worms over nuts, so allowed to cache ea, then given retention period (4 hrs) before recovery Degrade (worms allowed to decay) vs replenish grps (worms re- stocked) Findings: Fig 12.2 4 hrs 124 hrs 4 hrs 124 hrs

II. Timing: Techniques II. Timing: Techniques Duration estimation : discrimination procedure in which discriminative stimulus is duration of event Use modified DMS procedure in which sample is stimulus of certain duration Peak procedure : discrete-trial variation of FI schedule used to study timing; ea trial begins w/ presentation of discrim stim & after specified interval, food pellet made avail if perform instrumental response (Fig 12.5) Training: light food available after 20s; noise food available Test: trials lasted 80+s w/o food available Findings: 0 20 40 60 80 Based on Fig 12.5
