Psychodynamic Perspectives on Personality01:27

Psychodynamic Perspectives on Personality

1.5K
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...

The Behavioral Perspective on Personality

804
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.

Criticisms of the Evolutionary Perspective

346
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...

Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

994
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...

Changes in Skin Color: Clinical Perspectives

3.3K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.
Albinism
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Electrical Current01:10

Electrical Current

6.8K
Electrical current is defined as the rate at which charge flows. When there is a large current present, such as that used to run a refrigerator, a large amount of charge moves through the wire in a small amount of time. If the current is small, such as that used to operate a handheld calculator, a small amount of charge moves through the circuit over a long period of time. The SI unit for current is the ampere (A), named for the French physicist André-Marie Ampère (1775–1836).

Area of Science:

  • Hematology
  • Oncology
  • Pathology

Background:

  • Plasmablastic lymphoma (PbL) is a rare, aggressive B-cell malignancy characterized by CD20-negative neoplastic cells resembling plasmablasts.
  • Initially associated with HIV, PbL is now recognized in transplant recipients and immunocompetent individuals.
  • The molecular drivers and diagnostic challenges of PbL remain significant due to its rarity.

Purpose of the Study:

  • To comprehensively review the clinical and biological characteristics of Plasmablastic lymphoma.
  • To discuss the diagnostic criteria and differential diagnoses for PbL.
  • To explore current and potential future therapeutic options for PbL.

Main Methods:

  • Extensive literature search on Plasmablastic lymphoma.
  • Analysis of clinical presentations, pathological features, and molecular characteristics.
  • Review of treatment outcomes and emerging therapeutic strategies.

Main Results:

  • PbL exhibits CD20 and PAX5 negativity with plasmacytic markers (CD38, CD138, MUM1/IRF4, Blimp1, XBP1).
  • Associated with Epstein-Barr virus and MYC gene rearrangements.
  • Requires differentiation from other CD20-negative B-cell neoplasms.
  • Prognosis is poor with limited treatment options and no standard of care.

Conclusions:

  • Accurate diagnosis of PbL relies on recognizing its unique clinical, morphological, and immunophenotypic features.
  • Current treatment strategies offer limited efficacy, emphasizing the urgent need for novel therapeutic approaches.
  • Further research into the molecular basis of PbL is crucial for developing targeted therapies and improving patient outcomes.
