Adults use many forms of information when deciding how to act in any situation. We are investigating the types of information infants use when determining how to act in a novel reaching task. We are looking at costs (how far they must reach; Study 1) and the social value of the object they are acting toward (Study 2). In Study 1 (ongoing), we tested 6-month-olds (n=25) and 9-month-olds (n=14). Infants completed a warm-up task to measure their maximum reach. During test trials, they were presented toys at 3 different distances: one inch away (Easy condition), one inch past maximum reach (Hard condition), and 27 inches away (Impossible condition; Figure 1). Infants reached more in the easy (93.2%) than the hard (72.6%, β=-1.90, p<0.0001) and impossible conditions (19.3%; β=-5.45, p<0.0001; Figure 2A). Infants also reached more in the hard than the impossible condition (β=-3.5, p<0.0001; Figure 2A). A within-subjects one-way ANOVA revealed a main effect of condition on infants' latency to reach F(2,73)=127, p<0.0001. The average latency increased from easy (2.61+/-2.05seconds), through hard (4.93+/-3.21seconds), to impossible (9.29+/-1.13seconds; Figure 2B). This indicates that infants are less likely to reach for objects when costs are high. In Study 2 an actor will manipulate one toy to be exciting (“I love this toy!”) and one toy to be boring (“Eh”), 3 times, 10 seconds each. We hypothesize that if infants use social value in their decision-making process, they will persist more when reaching for the exciting toy, particularly in the hard condition when reaching is costly. Even though infants engage in less complex decisions than adults, we are able to see evidence of decision-making processes in infants’ actions, supporting the idea that humans’ ability to perform these processes may emerge during early infancy.
