Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled. Can you think of an example in which having an audience could improve performance? One common example is sports. Skilled basketball players will be...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell! Since enzymes help control the rate of reactions, their activity is regulated so that appropriate amounts of starting materials, intermediate metabolites, and products are maintained in the cell. Excessive build-up or depletion of...

The plasma membrane, a critical structure in cellular biology, houses an array of transporters, or carrier proteins, interspersed within its lipid bilayer. These proteins play a crucial role in solute transport through facilitated diffusion, a form of passive diffusion that uses transporters to move the molecules across the membrane. In this process, substrates such as organic compounds and ions interact with a transporter on one side, triggering conformational changes in proteins that enable...

The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a membrane via...

FAQs
Attention can increase the availability of information relevant to a response, making that response faster or more likely. In contrast, competing signals can divert attention or activate alternative responses, suppressing the target behavior. Comparing performance under conditions with relevant cues and competing cues helps researchers examine how organisms select among possible actions.
Preceding information can prepare or bias an upcoming response before the target event occurs, while concurrent cues influence selection during the response process itself. Both may facilitate or inhibit behavior, but their effects can be separated by examining when each signal appears and whether performance changes in speed, accuracy, or response probability.
Learned associations can connect particular stimuli with specific responses, increasing the tendency to produce an associated action or suppressing behavior when competing associations are activated. This mechanism helps explain why the same cue may produce different outcomes across contexts. It also links facilitation inhibition effects to learning, adaptation, and changing behavioral demands.
Reaction time, accuracy, response probability, and behavioral persistence provide complementary evidence. Faster responses may indicate facilitation, whereas slower or less frequent responses may indicate inhibition, although performance must be interpreted in relation to the comparison condition. Persistence can show whether an influence affects only immediate performance or continues to shape behavior over time.
A study can present stimuli, responses, or social contexts with relevant preceding information, concurrent cues, or competing signals, then compare behavior across conditions. Researchers may record reaction time, accuracy, response probability, or persistence. These comparisons indicate whether a condition increases or decreases performance and help distinguish attentional, competitive, and learned influences.
The framework is relevant to perception, cognition, motor control, and social behavior. In each area, researchers can examine how contextual information or competing signals changes action selection and performance. Findings may clarify how organisms adapt to changing conditions, make decisions, learn stimulus-response relationships, and regulate behavior when several possible responses are available.
