When a small bakery uses Instagram to showcase its latest pastries and engages directly with customers through comments and direct messages, it's leveraging the power of social media marketing. Social media marketing connects businesses with their audience to build brand awareness, increase sales, and drive website traffic. It is a cost-effective strategy that reaches over 3.6 billion users worldwide, providing businesses with an unparalleled platform for visibility and customer engagement. By...

Social Scripts
0 Views •
2020
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter), the opening...

Perspectives on Social Psychology

Social Psychology is a complex field—one that investigates how social contexts affect people’s actions, thoughts, and attitudes. It brings the scientific method into our everyday lives by addressing questions relevant to interactions amongst individuals near and far or even over the internet. For example, the video about ostracism details an approach to induce feelings of exclusion without direct face-to-face contact. These videos are meant to show the wide reactionary nature of human beings,...

The Social Dimension of Stress: Experimental Manipulations of Social Support and Social Identity in the Trier Social Stress Test

Previous research on the social dimension of stress has focused on two important variables: social identity and social support. This protocol introduces an effective experimental manipulation of these two social variables and describes their implementation in a standard stress induction paradigm (Trier Social Stress Test).

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do. A good example of social proof is from laugh tracks on television shows. Fullery & Skeffington (1974) found that adding group laughter sounds to material increased how humorous the participants perceived that material, regardless of whether the content itself was funny or not. By adding a laugh...

SOC medium supplies tryptone and yeast extract as nutrients, salts as part of the growth environment, and glucose as an additional energy source. Together, these components support cellular recovery after heat shock or electroporation. This nourishment helps cells resume growth before researchers expose them to selective agar, where suitable transformants are expected to form colonies.
Shaking keeps cells mixed and promotes growth during post-transformation recovery. In the source workflow, that physical condition is linked with membrane repair and expression of antibiotic-resistance genes, two events that improve a cell's readiness for selection. Without this recovery period, recently treated cells may be less prepared to survive and produce visible colonies on selective agar.
Separating recovery from selection gives transformed cells time to repair membranes and express antibiotic-resistance genes before they encounter selective agar. SOC medium supplies nutrients during this interval, while shaking promotes growth. This sequencing improves the likelihood that successfully transformed bacteria will survive selection and form visible colonies.
After transformation by heat shock or electroporation, researchers transfer the cells into SOC medium and incubate them with shaking. They then plate the recovered cells on selective agar. This sequence gives cells an opportunity to repair membranes, resume growth, and express antibiotic-resistance genes before selection, allowing transformed colonies to be isolated.
The recovery medium contains tryptone, yeast extract, salts, and glucose, providing the nutrient-rich environment used after DNA delivery. Shaking is the associated incubation condition, and selective agar follows the recovery step. Together, these materials and conditions connect cellular repair and growth with isolation of colonies from successfully transformed cells.
It supports plasmid cloning, recombinant DNA workflows, and bacterial genetic studies by improving recovery before selection. The practical outcome is a greater likelihood that successfully transformed cells will develop into visible colonies, which researchers can isolate after plating. Thus, the step bridges DNA introduction and colony-based identification of transformants.
