Get title in thumbnail array

hello,

is it possible to get the title of the post in the array?

<img data-slider='<?php the_ID(); ?>'/> <?php the_post_thumbnail(
	array(200, 200),
	array(
		'class' => 'thumbnail-slider',
		'alt' => 'post thumbnail',
		'title' => $title,
		'data-slider' => $id
	)
); ?>

i get the ID, but not the title (I also tried $post-title)
