The extracellular matrix (ECM) is a network of molecules that provide a structural framework for cells and tissues and helps facilitate intercellular communication. Three-dimensional cell culture techniques have been developed to more accurately model this extracellular environment for in vitro study. While many cell processes during migration through 3D matrices are similar to those required for movement across rigid 2D surfaces, including adherence, migration through ECM also requires cells...

Source: Peter Mende-Siedlecki & Jay Van Bavel—New York University When we are considering a tough choice between two or more attractive options, we often end up actively weighing the pros and cons of each alternative. By reflecting on their advantages and disadvantages, we attempt to fit a complex, subjective decision into an orderly set of criteria. However, research in psychology suggests that this sort of introspective approach might not always yield the most optimal outcomes.1 In other...

Source: Laboratories of Jonas T. Kaplan and Sarah I. Gimbel—University of Southern California Decision-making is an important component of human executive function, in which a choice about a course of action or cognition is made from many possibilities. Damage to the inferior parts of the frontal lobes can affect a person's ability to make good decisions. However, while decision-making deficits can have a large impact on one's life, these deficits can be difficult to quantify in the laboratory.

The BoTest Matrix botulinum neurotoxin (BoNT) detection assays rapidly purify and quantify BoNT from a range of sample matrices. Here, we present a protocol for the detection and quantification of BoNT from both solid and liquid matrices and demonstrate the assay with BOTOX, tomatoes, and milk.
FAQs
Weights make the comparison sensitive to the relative importance of each criterion. A highly valued factor contributes more strongly to the combined result than a less important one, so changing the weights can alter which option appears preferable. This feature helps reveal trade-offs and shows how priorities, rather than scores alone, shape the final recommendation.
The matrix separates criteria, priorities, and option scores, making subjective influences easier to inspect. Researchers can examine whether a preference reflects a particular criterion, an assigned weight, or an evaluation of one option. In psychology, this structure helps identify how cognitive biases, incomplete information, or personal preferences may affect judgment and choice.
A structured format improves consistency and transparency, but users still choose the criteria, decide how important each factor is, and assign scores to alternatives. Those choices can reflect personal preferences or incomplete information. The matrix therefore does not remove judgment; instead, it makes the reasoning and possible sources of disagreement more visible.
Begin by listing the alternatives and the criteria relevant to the choice. Assign relative weights when some criteria matter more than others, then score each option against those criteria. Combining the scores produces an overall comparison. Reviewing the resulting priorities and trade-offs can show which assumptions or preferences most influence the outcome.
A shared matrix gives participants a common structure for discussing alternatives, criteria, and priorities. Rather than presenting only a preferred option, the group can explain how each score and weight contributed to the combined result. This makes reasoning more transparent, supports comparison of competing goals, and helps identify points where members hold different assumptions.
In psychology, matrices can support investigations of judgment, choice, and risk assessment by organizing how people evaluate competing alternatives. Researchers can examine the criteria participants consider, the priorities they assign, and the effects of cognitive biases or incomplete information. The resulting comparisons help clarify how individuals balance competing goals during decision-making.
