Communication Objectives
870
Communication objectives are crucial strategic goals in marketing, serving as the backbone for promotional activities.
Clear communication objectives help marketers ensure that each piece of communication serves a specific purpose, enhancing the overall impact and efficiency of their marketing efforts. Communication objectives should be SMART: specific, measurable, achievable, relevant, and time-bound.
They should align with marketing goals and support brand positioning, ensuring promotional...

14:38Creating Objects and Object Categories for Studying Perception and Perceptual Learning
12.2K
We describe a novel methodology for creating naturalistic 3-D objects and object categories with precisely defined feature variations. We use simulations of the biological processes of morphogenesis and phylogenesis to create novel, naturalistic virtual 3-D objects and object categories that can then be rendered as visual images or haptic...
