Final answer:
The statement about the Job Characteristics Model missing information processing demands as a category is false. Information processing relates to the core dimensions of skill variety and task significance within the model.
Step-by-step explanation:
The statement that one category of job characteristics missing from the job characteristics model is the information processing demands of the job is false. The Job Characteristics Model, which was developed by Greg R. Oldham and J. Richard Hackman, includes five core job dimensions: skill variety, task identity, task significance, autonomy, and feedback. While information processing demands are not explicitly called out as a separate category within the model, they can be related to the core dimension of skill variety, which encompasses the mental and physical skills required to perform a job. Additionally, complex information processing could also relate to task significance, if the information handled is vital to the completion of an important task.
