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 objects.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Visual masking is a term used by perceptual scientists to refer to a wide range of phenomena in which in an image is presented but not perceived by an observer because of the presentation of a second image. There are several different kinds of masking, many of them relatively intuitive and unsurprising. But one surprising and important type of masking is called Object Substitution Masking. It has been a focus of research in vision...

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University In a staggeringly complex and engaging world, it is crucial to selectively process some stimuli at the expense of others. Experimental psychologists call this ability attention. Specifically, visual attention refers to the ability to selectively process aspects of a visual scene. Many paradigms used to study visual attention involve brief, punctuated, and repeated trials. However, everyday situations often place sustained demands...

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...
FAQs
Consistent timing and scoring rules reduce variation caused by when or how an assessment is completed. A symptom score collected under comparable conditions can be interpreted more reliably across visits, patients, or treatment groups. This consistency helps distinguish genuine change from differences caused by inconsistent assessment practices and supports reproducible clinical and research conclusions.
These sources capture different aspects of the same clinical problem. Patient reports describe experienced severity or functional impact, clinician observations add structured examination findings, and physiological measurements provide related measurable data. Examining them together can help connect subjective symptoms with observable or physiological information without relying solely on an unstructured clinical impression.
A baseline establishes the patient’s status before a treatment, disease change, or other clinical intervention is evaluated. Later scores can then be compared with that starting point to show whether symptoms improved, worsened, or remained stable. In medicine, this comparison supports more consistent interpretation of individual progress and treatment response.
A typical workflow selects a standardized questionnaire, rating scale, structured examination, or digital monitoring approach suited to the symptom being evaluated. The assessment is administered at defined times, scored according to established rules, and compared with earlier results. Clinicians can then document symptom trajectories, evaluate functional impact, and identify changes requiring attention.
The format depends on which information must be captured. Questionnaires and rating scales can organize patient-reported severity or impact, while structured examinations record clinician-observed findings. Digital monitoring can support repeated symptom measurement over time, and physiological findings can add measurable context. Using an appropriate format improves consistency between the assessment goal and the resulting data.
Standardized symptom measurements create more consistent study endpoints, meaning defined outcomes used for analysis. Consistent endpoints allow investigators to compare treatment responses, examine symptom change statistically, and relate reported experiences to disease progression or physiological data. This improves the interpretability of clinical research and supports clearer evaluation of whether an intervention produces meaningful change.
