Pulp schticks are special in that they are not linked to any one ability. In the list of Schticks there are separate categories for different Skills and Attributes, each with a number of related pulp schticks. Thus, pulp schticks can also be termed attribute schticks or skill schticks.
In order to learn a skill schtick, you must either 12 or more in the relevant skill. There is no requirement for Attribute schticks, but it usually pays to have a good value when you actually use the schtick.
Pulp schticks are generally abilities that are not directly supernatural, but represent some special knack or ability not commonly available. Some represent unusual specializations. In many cases, it is possible to do what the pulp schtick does as a stunt, but the schtick lets you do it repeatedly and reliably.
