The Placebo Effect01:54

The Placebo Effect

7.0K
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Bystander Effect02:09

Bystander Effect

10.4K
The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.

Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

947
While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...

Nociception01:44

Nociception

34.3K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Social Proof00:52

Social Proof

32.6K
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.

Blind Procedures02:07

Blind Procedures

13.9K
Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

    Area of Science:

    • Psychosomatic Medicine
    • Clinical Psychology
    • Patient-Provider Communication

    Background:

    • The nocebo effect, a negative counterpart to the placebo effect, is increasingly recognized in healthcare.
    • Negative expectations and patient distress can physiologically impact treatment outcomes.
    • Research indicates the nocebo effect may be more potent than the placebo effect.

    Purpose of the Study:

    • To highlight the significance of the nocebo effect in clinical practice.
    • To underscore the impact of patient expectations on treatment results.
    • To emphasize the role of healthcare communication in mitigating negative effects.

    Main Methods:

    • Review of emerging evidence on the nocebo effect.
    • Analysis of patient-provider interactions and their psychological impact.
    • Examination of the relationship between anxiety, pain expectation, and physiological response.

    Main Results:

    • The nocebo effect is prevalent, particularly in patient-provider interactions.
    • Patients' perception of being misunderstood by healthcare professionals can induce distress.
    • Negative expectations, such as anticipating pain, demonstrably increase experienced pain levels.

    Conclusions:

    • Effective patient communication is vital for positive treatment outcomes.
    • Managing patient anxiety and negative expectations is a key factor in healthcare.
    • Understanding and addressing the nocebo effect can improve therapeutic success.
