Answer to Question 1
Beck identifies a number of thinking errors including (1) arbitrary inference (drawing conclusions without supportive evidence), (2) selective abstraction (focusing on a detail that ignores the more important big picture), (3) overgeneralization (drawing sweeping conclusions based on limited information), (4) dichotomous thinking (thinking in black or white terms rather than shades of gray), (5) magnification and minimization (exaggerating small events or trivializing big events), and (6) personalization (taking responsibility for events that are not under one's control).
Answer to Question 2
