The crosses (x) indicate eigenfrequencies from the discrete spectrum, and plusses (+) those from the continua.
Two plusses indicate strong effects in at least half the cells in the group.
The plusses show the comparisons for the control monkeys.
Developmental data from individual animals are connected points; data from animals tested only once are shown as plusses.
Plusses show data for agematched control animals.
So there are plusses and minuses within the overall economy.
I agree, it would and to that extent it has some plusses.
The attitude we must take in our judgment is to study both the plusses and minuses and to realise that a lot has been achieved.
