Figure 2.

Overview of affective bias test study design for experiment 2.

Figure illustrates protocol to test acute treatment effects on new learning and development of the affective state-induced biases. Animals undergo pairing sessions with drug treatment with/without manipulation (e.g. on days 1 and 3) versus control treatment (e.g. on days 2 and 4). The development of the affective biases is then measured by the choice test (day 5).
