Cohesion

Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature. On a surface,...

Measurement of Aggregate Cohesion by Tissue Surface Tensiometry

We describe a method of measuring binding energy, expressible as tissue surface tension, between cells within 3D tissue-like aggregates. Differences in tissue surface tension have been demonstrated to correlate with invasiveness of lung, muscle, and brain tumors, and are fundamental determinants of establishing spatial relationships between different cell types.

We present a procedure, ASTM D7998-19, for a rapid and more consistent evaluation of both dry and wet strength of adhesive bonds on wood. The method can also be used to provide information on strength development as a function of temperature and time or strength retention up to 250 °C.

This manuscript presents a detailed method for generating X-chromosome arm probes and performing fluorescence in situ hybridization (FISH) to examine the state of sister chromatid cohesion in prometaphase and metaphase I arrested Drosophila oocytes. This protocol is suitable for determining whether meiotic arm cohesion is intact or disrupted in different genotypes.

Surface Tension, Capillary Action, and Viscosity

Surface Tension The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...
FAQs
Repeated interaction gives members opportunities to develop mutual support, effective communication, and shared expectations. Over time, these experiences can strengthen feelings of connection and belonging while making coordinated behavior easier. In psychology, the mechanism matters because cohesion is not only a personal attitude; it also develops through ongoing social exchange that links relationships with commitment to common goals.
Shared norms provide expectations about how members should communicate, support one another, and pursue common goals. When those expectations become broadly understood, they can reduce uncertainty about group behavior and help members coordinate their efforts. This helps explain why cohesion is associated with trust and collective functioning, rather than being limited to how positively members feel about each other.
Perceived similarity can make members feel more connected, while interdependence highlights how one person’s actions relate to others’ outcomes. Both processes can encourage belonging and commitment, but they do so through different routes: similarity emphasizes perceived commonality, whereas interdependence emphasizes reliance among members. Together, they help explain variation in cohesion across social groups.
Cohesion can influence several group processes at once. Stronger connection and commitment may support motivation and cooperation, while effective communication and trust can help members coordinate behavior during collective decision-making. The expected result is not merely greater interaction; cohesion can shape how consistently members participate, work toward shared goals, and manage the demands of group performance.
A useful psychological analysis examines members’ sense of belonging and connection, their commitment to one another and common goals, and the presence of mutual support, communication, shared norms, similarity, or interdependence. Researchers can then relate these features to motivation, cooperation, decision-making, and performance. This approach connects the group’s relational qualities with observable collective outcomes without reducing cohesion to a single behavior.
The concept applies across workplaces, classrooms, sports teams, therapy groups, and community organizations. These settings differ in purpose, yet each depends on relationships and coordinated participation. Studying cohesion in multiple contexts helps psychologists consider how belonging, communication, and shared commitment relate to persistence, conflict management, and collective outcomes under different social conditions.
Strengthening cohesion may improve participation, persistence, conflict management, and collective outcomes. Its value therefore extends beyond maintaining positive relationships: a more connected group may be better positioned to sustain involvement and address disagreement while pursuing common goals. In applied psychology, these outcomes make cohesion relevant to efforts to understand or support functioning in workplaces, classrooms, teams, and communities.
