Thinking Too Much Impairs Decision-Making

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...

An Automated System for Sound Localization Testing in Hearing-Impaired Listeners
0 Views •
2026
This protocol introduces an automated sound localization testing system with precise loudspeaker placement and integrated response analysis, validated in normal-hearing participants and participants with single-sided deafness. It provides a reproducible method to assess spatial hearing and supports functional classification using the International Classification of Functioning, Disability and Health (ICF) framework.

Evaluating Motor Impairment in C. elegans Models Using the Radial Locomotion Assay
0 Views •
2025
This video demonstrates the use of a radial locomotion assay to evaluate motor dysfunction in C. elegans expressing either wild-type or ALS-mutant human TDP-43 protein. Worms with varying levels of wild-type or mutant TDP-43 expression are allowed to crawl, and their movement is measured by the radial distance traveled from the central point on the assay plate. The assay distinguishes between mild, moderate, and severe motor impairments based on the distance traveled by the different C. elegans...
FAQs
Brain injury and disease can disrupt neural circuits that support attention, memory, motivation, impulse control, and emotional regulation. The resulting changes may appear in actions, emotional responses, cognition, or social behavior, depending on which functions are affected. Identifying the pattern of affected abilities helps clinicians connect observed behavior with possible neurological, psychiatric, developmental, or medical contributors.
Altered neurotransmitter signaling can change how brain circuits regulate motivation, attention, emotional responses, and impulse control. Substance exposure and other physiological changes may also disturb these systems, producing noticeable behavioral or cognitive changes. Considering these biological influences prevents clinicians from interpreting behavior in isolation and supports a broader assessment of possible underlying conditions.
The duration and stability of changes help clinicians determine whether an observed problem may reflect a temporary effect or a more persistent disorder. History, repeated observation, cognitive testing, and functional assessment can reveal whether difficulties remain consistent across time and settings. This distinction influences diagnostic reasoning, treatment planning, rehabilitation needs, and interpretation of outcomes.
Attention, memory, motivation, impulse control, emotional regulation, and social responses provide complementary information about the pattern of impairment. A person may show difficulty in one area while retaining other abilities, so clinicians examine the combination rather than relying on a single behavior. This profile helps describe severity and identify functional consequences relevant to care.
Evaluation combines a clinical history with direct observation, cognitive testing, and functional assessments. History establishes the nature and course of the change, while observation captures behavior in context. Cognitive and functional measures clarify how the problem affects thinking and everyday performance. Together, these sources help distinguish transient effects from persistent disorders and support a more informed diagnosis.
Cognitive testing can clarify difficulties involving attention, memory, or related mental processes, while functional assessments show how those difficulties affect practical performance and social responses. Interpreting both types of information gives clinicians more than an isolated symptom description. The combined findings help characterize severity, identify meaningful limitations, and guide treatment or rehabilitation decisions.
A carefully characterized behavioral profile can support diagnosis, guide treatment selection, and identify rehabilitation needs. In research, the same measures help investigators track changes in brain and behavioral health over time and evaluate outcomes in conditions that affect behavior. Comparing patterns and severity before and after an intervention can show whether functioning has improved, remained stable, or worsened.
