As a subject matter expert in the field of Pokémon, I can provide you with the information you're looking for. In the Pokémon universe, certain types of attacks are more effective against others, and this is determined by the type chart.

English Answer:
Psychic-type moves are super effective against Poison-type Pokémon. This is because Psychic-type moves exploit the vulnerability that Poison-types have. As for Ghost-type Pokémon, they are immune to Poison-type moves, so we need to look at another type that is effective against them. Ghost-type Pokémon are weak against Dark-type and Ghost-type moves. Dark-type moves are particularly effective because they prey on the weaknesses that Ghost-types possess.

Chinese Translation:
在宝可梦世界中，某些类型的攻击对其他类型更为有效，这由类型相性表决定。
