P1- birds w “dietary wariness”: neophobia & dietary conservatism (neo wane)
-wariness is controlled? dont know: experiments on chicks - wariness deactivated & reactivated by different foods.
Found: single novel tasty food deactivate neophobia & diet conservatism of other novel colors.
-little prior experience to deactivate neophobia <—> more experience needed for diet.
-direct contact to overcome wariness, however can peck from observational learning.
-reinstating easier than deactivation
reinstate 使恢复原状
transient aversion 短暂厌恶
wane 衰落
wariness 謹慎
conservatism 保守主義
P2: how wariness is controlled?
try color foods - neophobic reduce
-palatable/ unpalatable (inhibit)
P3: deactivation — direct contact w food. Observation is not sufficient— surprising bc chicks as highly social animals
P4: alternative interpretation:
mental image of food - experience food- generalize to accept similar looking food of any color [color not the major part]
