Object Substitution Masking

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...

Sign Test for Matched Pairs

2025
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values. To conduct the sign test, we first calculate the differences in value between...

Multiple Object Tracking

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...

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.

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
Accuracy reflects whether the participant selected the correct correspondence, whereas reaction time captures how quickly the judgment was reached. Examining both measures helps separate successful performance from processing speed. A person may achieve high accuracy while taking longer, so the two outcomes offer complementary information about lexical-semantic processing, attention, and visual recognition.
Semantic memory supplies the stored conceptual knowledge needed to connect a written label with what it represents. In Word Object Matching, this memory-based step links language information to visual information rather than treating either source in isolation. Performance therefore helps researchers examine how meaning is accessed and coordinated across verbal and perceptual representations.
Several processes can shape performance: identifying the word, accessing its meaning, recognizing the visual object, maintaining attention, and comparing the two representations. Because these operations contribute to the same decision, changes in accuracy or response speed may reflect differences in lexical-semantic processing, visual recognition, or attention rather than a single ability alone.
Because the task pairs written language with object information, it places lexical-semantic processing and visual recognition within one decision. This combination lets psychologists examine coordination between language comprehension, semantic memory, and perception. It is consequently useful for investigating how verbal and visual information contribute together to a person's response.
Researchers should record both response accuracy and reaction time for each decision. Accuracy shows whether the word-object correspondence was judged correctly, while reaction time indicates the speed of processing. Together, these measures support analysis of lexical-semantic processing, visual recognition, and attention, giving a more informative profile than either measure alone.
Developmental studies can use the task to examine how language comprehension, semantic memory, visual recognition, and attention change as cognitive abilities develop. Comparing accuracy and reaction time across developmental groups can reveal differences in processing performance. The task therefore provides a way to study cognitive development through coordinated language and object judgments.
In studies of brain injury or neurological conditions, altered accuracy or reaction time can help characterize changes in language or conceptual processing. Researchers can use the resulting measures to examine how these conditions affect performance on coordinated word and object judgments. The task therefore provides evidence about changes in cognitive processing across clinical contexts.
