Social Scripts02:10

Social Scripts

10.2K
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 Sense of Self: Reflected Self-Appraisal and Social Comparison

55.5K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Long-term Depression01:05

Long-term Depression

33.2K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Social Exchange Theory02:06

Social Exchange Theory

39.5K
We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Social Proof00:52

Social Proof

31.5K
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.

Protein Networks02:26

Protein Networks

4.5K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Area of Science:

  • Computational psychiatry
  • Machine learning applications in mental health

Background:

  • Mental health conditions, particularly depression, represent a significant global health burden.
  • Social networking platforms generate vast amounts of user data, offering potential for mental health research.

Purpose of the Study:

  • To develop a deep learning model for classifying users with depression.
  • To leverage user-generated social media content for mental health detection.

Main Methods:

  • Utilized multiple instance learning to classify users based on post-level labels derived from user-level labels.
  • Generated temporal posting profiles by combining all possible post label categories.
  • Analyzed differences in posting patterns between depressed and non-depressed users.

Main Results:

  • Demonstrated clear distinctions in posting patterns between users with and without depression.
  • The combined likelihood of post label categories effectively represents these differences.
  • The deep learning model successfully classified users based on these temporal posting profiles.

Conclusions:

  • Social media posting patterns contain detectable signals of depression.
  • Deep learning, specifically multiple instance learning, is a viable approach for identifying mental health conditions from online data.
  • This methodology offers a promising avenue for scalable mental health screening and early detection.
