See the bit about mode local to buffer:

,----
| To make this mode local to the buffer use (make-variable-buffer-local ‘show-paren-mode), add something like this to your .emacs:
| 
| (defun lispy-parens ()
|   "Setup parens display for lisp modes"
|   (setq show-paren-delay 0)
|   (setq show-paren-style 'parenthesis)
|   (make-variable-buffer-local 'show-paren-mode)
|   (show-paren-mode 1)
|   (set-face-background 'show-paren-match-face (face-background 'default))
|   (if (boundp 'font-lock-comment-face)
|       (set-face-foreground 'show-paren-match-face 
| 			   (face-foreground 'font-lock-comment-face))
|     (set-face-foreground 'show-paren-match-face 
| 			 (face-foreground 'default)))
|   (set-face-foreground 'show-paren-match-face "red")
|   (set-face-attribute 'show-paren-match-face nil :weight 'extra-bold))
| 
| (add-hook 'scheme-mode-hook 'lispy-parens)
| (add-hook 'lisp-mode-hook 'lispy-parens)
| (add-hook 'emacs-lisp-mode-hook 'lispy-parens)
