Final answer:
Selective abstraction does not involve taking all details of an event, but focuses on a single detail often at the expense of other information, which is a false representation of Beck's concept.
Step-by-step explanation:
The statement that according to Beck, selective abstraction is when clients take all the details of an event and use it to reinforce negative schemas and support their maladaptive core beliefs is false. Selective abstraction is actually the cognitive bias where an individual focuses on a single detail, often taken out of context, and ignores other more salient features of the situation. This can indeed contribute to negative thinking patterns and reinforce unhealthy beliefs, but it does not involve considering all the details of an event as the statement suggests. Selective abstraction and the tendency to focus on specific information while ignoring other details can lead to confirmation bias, a phenomenon where individuals seek out or interpret information in a way that confirms their pre-existing beliefs or hypotheses. This focus on selective pieces of information rather than the entire context, can be linked to the simplistic perception and recollection of events, which does not present a full or complete picture of the world but instead highlights certain aspects.
