Problem: We might expect some neurons to have strong responses to any stimulus and others to have consistently weak responses. There would then be a strong relationship between tone response and call response.
Required:
From the scatterplot of monkey call response against pure-tone response in Figure 7.6 what would you estimate the correlation r to be?
(i) -0.6
(ii) -0.1
(iii) 0.1
(iv) 0.6
