What are Populations and Communities?

Community Based Intervention

Community Based Intervention

Community-based interventions in mental health represent a paradigm shift from institution-centered care to treatments embedded within the fabric of local communities. By prioritizing inclusion and leveraging existing societal structures, this approach fosters a supportive environment conducive to addressing mental health challenges while promoting individual dignity and agency.
Foundations of Community Mental Health Programs
Central to the success of community-based interventions is the...

Gene Regulation in Microbial Communities: Quorum Sensing

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

Relationship Formation

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Ecological Succession

Ecological Succession

Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Background:

Categorical explanations use labels to describe properties of objects.
The perceived quality of these explanations may depend on factors beyond substantive information.

Purpose of the Study:

To investigate the influence of label entrenchment on the perceived quality of categorical explanations.
To determine if this effect persists even when labels lack substantive information or when experts are involved.

Main Methods:

Four experiments were conducted to test the effect of label entrenchment.
Participants judged the quality of categorical explanations using labels with varying degrees of community acceptance and usage.

Main Results:

Explanations with unentrenched labels were rated as less comprehensive and natural, irrespective of causal information.
This effect was observed even when labels were mere names or used by experts, and for categories lacking causal structure.
Participants often failed to recognize the impact of label entrenchment on their judgments.

Conclusions:

Label entrenchment significantly impacts the perceived quality of categorical explanations.
Reliance on community cues for label quality persists even when these cues are uninformative, highlighting the role of communal knowledge in categorization.
