“…Therefore, in morning (and afternoon) sessions the rat goes to place 1 50% of the trials and to place 2 50% of the trials. This explains the place preference (but no TPL learning) that is seen in low-response-cost daily TPL tasks Thorpe et al, 2003).…”

“…Because previous research (Thorpe et al, 2003) has shown that there are individual differences in the timing strategies used by rats in time-ofday discrimination tasks, we decided to first look at the data for each rat rather than averaging across rats. The baseline and probe data for each rat are shown in Figure 4.…”

“…Thorpe, Bates, and Wilkie (2003) attempted to demonstrate daily TPL in rats using a variety of tasks including a place preference task, a semiaversive water maze task, a radial arm maze task, and a T-maze task. They found that rats learned the locations of the food (or of the platform, in the case of the water maze task), as shown by their tendency to prefer those locations over others that had never been associated with food (or platforms).…”

“…Some researchers have found daily TPL in operant response tasks (Carr & Wilkie, 1997a, 1997b, 1999Mistlberger, de Groot, Bossert, & Marchant, 1996;Pizzo & Crystal, 2002), whereas others using very similar paradigms and similar reinforcement schedules have failed to find it (Boulos & Logothetis, 1990;Thorpe et al, 2003;White & Timberlake, 1990). Although Widman et al (2000) believe that response-cost ratios (the relative cost of making an error) are the critical determinants of whether an animal learns a time-place task, it is not clear from a theoretical perspective why this should be the case.…”

“…Both procedures produced robust changes in behavior (cf. Means et al 2000ab; Thorpe et al, 2003) similar to those seen when rats are given discriminations where the configurations of contextual with auditory cues signalled whether or not food would be delivered (e.g., Honey & Watt, 1999). There are two specific aspects of the results that are worth dwelling on: The difficulty of the two configural discriminations and the nature of the cues correlated with times of day that the rats might have used.…”

Configural integration of temporal and contextual information in rats: Automated measurement in appetitive and aversive preparations

et al. 2015

Two experiments investigated the capacity of rats to learn configural discriminations requiring integration of contextual (where) with temporal (when) information. In Experiment 1, during morning training sessions, food was delivered in context A and not in context B, whereas during afternoon sessions food was delivered in context B and not in context A. Rats acquired this discrimination over the course of 20 days. Experiment 2 employed a directly analogous aversive conditioning procedure in which footshock served in place of food. This procedure allowed the acquisition of the discrimination to be assessed through changes in activity to the contextual+temporal configurations (i.e., inactivity or freezing) and modulation of the immediate impact of footshock presentations (i.e., post-shock activity bursts). Both measures provided evidence of configural learning over the course of 12 days, with a final test showing that the presentation of footshock resulted in more post-shock activity in the nonreinforced than reinforced configurations. These behavioral effects reveal important parallels between (i) configural discrimination learning involving components allied to episodic memory and (ii) simple conditioning.

Time-space learning in homing pigeons (Columba livia): orientation to an artificial light source

Time-space learning reflects an ability to represent in memory event-stimulus properties together with the place and time of the event; a capacity well developed in birds. Homing pigeons were trained in an indoor octagonal arena to locate one food goal in the morning and a different food goal in the late afternoon. The goals differed with respect to their angular/directional relationship to an artificial light source located outside the arena. Further, the angular difference in reward position approximated the displacement of the sun's azimuth that would occur during the same time period. The experimental birds quickly learned the task, demonstrating the apparent ease with which birds can adopt an artificial light source to discriminate among alternative spatial responses at different times of the day. However, a novel midday probe session following successful learning revealed that the light source was interpreted as a stable landmark and not as a surrogate sun that would support compass orientation. Probe sessions following a phase shift of the light-dark cycle revealed that the mechanism employed to make the temporal discrimination was prevailingly based on an endogenous circadian rhythm and not an interval timing mechanism.
