Blind Procedures

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...

Blinding01:11

Blinding

4.0K
Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Obedience

According to obedience research, we may harm others under the forceful pressures of an authority figure (Milgram, 1974). How about if the inappropriate orders were delivered with less force? The increasing interdependence between nurses and physicians compelled Hofling and his colleagues to explore nurses’ reactions to a potentially harmful medical request made by the perceived authority figure, the doctor (Hofling, Brotzman, Dalrymple, Graves, & Pierce, 1966). In this situation,...

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Psychosurgery

2.1K
Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Area of Science:

  • Medical Education
  • Surgical Training
  • Simulation-Based Learning

Background:

  • Supervisor feedback is crucial in medical education.
  • The impact of positive versus negative feedback on surgical trainees' performance and perception remains under-explored.

Purpose of the Study:

  • To evaluate the effect of positive and negative supervisor feedback on surgical trainee performance and satisfaction in a simulated environment.
  • To analyze procedural errors, operating time, and trainee perception in response to different feedback styles.

Main Methods:

  • A blinded, randomized study involving surgical trainees performing a simulated suturing task twice.
  • Assessment of performance metrics (procedure time, errors) and trainee satisfaction following positive or negative feedback.
  • Inclusion of a reflection period between task repetitions.

Main Results:

  • Negative feedback adversely affected the change in procedure time between the two tasks.
  • Trainees receiving negative feedback actively sought cues for improvement from the supervisor.
  • Negative supervisor feedback has the potential to negatively impact performance elements.

Conclusions:

  • While negative feedback may adversely affect surgical training performance, trainees demonstrate a willingness to improve by seeking guidance.
  • Feedback style significantly influences trainee performance and perception in simulated surgical tasks.
  • Further research is needed to optimize feedback strategies in surgical education.
