Page 8 of 11 2. You are curious about the effect of sleep loss on people's performance for a variety of tasks. Sleep loss appears to have a greater impact on tasks that require concentration and attention compared to more automatic tasks. You also wanted to examine whether sleep loss might affect people's ability to process emotional information. To formally test these hypotheses, you used three tasks: a lexical decision task (an automatic task, in which participants had to decide if a letter string is a word or a non-word), a target detection task (an attention task, in which participants have to detect a target pattern in a picture), and a facial expression task (an emotion task, in which participants have to identify the subtle emotions displayed by a face). Half the participants had normal sleep, and the other half were sleep-deprived for 24 hours. For both the normal-sleep group and the sleep-deprived group, one third performed the lexical decision task, one third performed the target detection task, and one third performed the emotion task. The following table shows the group means on each task measured as the percentage of trials performed correctly. _ Lexical decision task Target detection task Facial expression task automatic attentional emotional _--_ Slee- de-rived a).
