Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.6K
The psychodynamic perspective in psychology asserts that most personality functions operate unconsciously, outside of awareness. This means that the motives and emotions driving behavior often remain hidden, automatically buried in the unconscious mind as a defense mechanism to shield us from psychological distress. According to this theory, the unconscious mind contains thoughts, memories, and emotions that are too disturbing to face directly.
Psychodynamic theorists argue that unconscious...

Social Cognitive Perspective on Personality

1.0K
Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Criticisms of the Evolutionary Perspective

381
In a study where individuals posing as strangers offered compliments and proposed casual sex to students, the responses differed significantly based on gender. Not a single woman accepted the proposal, while 70% of the men agreed. This outcome provides a useful scenario to explore through the lens of evolutionary psychology and social learning theory, highlighting the diverse perspectives on human sexual behaviors.
Evolutionary psychology provides one explanation for these findings, suggesting...

The Behavioral Perspective on Personality

854
Behaviorists view personality as primarily shaped by environmental reinforcements and consequences. According to this perspective, behavior is influenced by external stimuli, and individuals adjust their actions based on rewards and punishments. Over time, learning histories — accumulated patterns of reinforcement — play a significant role in shaping personality. Behaviors that lead to positive outcomes are reinforced, while those resulting in negative outcomes are diminished.

What is an Experiment?01:12

What is an Experiment?

19.2K
An experiment is a planned activity carried out under controlled conditions. The purpose of an experiment is to investigate the relationship between two variables. When one variable causes change in another, we call the first variable the explanatory or independent variable. The affected variable is called the response or dependent variable. In a randomized experiment, the researcher manipulates values of the explanatory variable and measures the resulting changes in the response variable. The...

Gene Therapy00:59

Gene Therapy

27.7K
Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Area of Science:

  • Oncology
  • Immunotherapy
  • Drug Development

Background:

  • Osteosarcoma (OS) is a primary bone cancer with challenging treatment outcomes.
  • Current standard care involves chemotherapy and surgery, with limited survival improvements.
  • Immunotherapy, particularly immunoconjugates, is an emerging therapeutic avenue.

Purpose of the Study:

  • To review immunoconjugates targeting osteosarcoma surface antigens.
  • To evaluate preclinical and clinical data on immunoconjugate efficacy in OS.
  • To explore future directions for immunoconjugate therapy in osteosarcoma.

Main Methods:

  • Literature review of in vitro and in vivo studies on OS immunoconjugates.
  • Analysis of clinical trial data for antibody-drug conjugates in osteosarcoma.
  • Examination of potential antibody carriers for future immunoconjugate development.

Main Results:

  • Preclinical studies demonstrate encouraging results for immunoconjugates against OS.
  • Clinical experience with glembatumumab vedotin offers insights into antibody-drug conjugate efficacy and patient selection.
  • Ongoing trials with unconjugated antibodies may identify new carriers for immunoconjugates.

Conclusions:

  • Immunoconjugates represent a promising therapeutic strategy for osteosarcoma.
  • Further research and clinical trials are needed to fully realize the potential of immunoconjugates in OS treatment.
  • Targeted therapies like immunoconjugates may enhance patient outcomes for this aggressive bone malignancy.
