Framing Effects03:26

Framing Effects

7.4K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

129
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Relative Risk01:12

Relative Risk

174
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

The Availability Heuristic01:08

The Availability Heuristic

6.0K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

Surveys02:16

Surveys

14.8K
Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.

Factors Affecting Perception01:25

Factors Affecting Perception

1.6K
Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...

风险感知调查中的有条件措辞可以膨胀感知风险和预防行为之间的关系. 然而,这种偏差很小,并不能证明在研究中忽略了条件风险指标.

科学领域:

  • 行为科学 行为科学
  • 风险感知研究 风险感知研究

背景情况:

  • 评估风险感知的最佳实践包括有条件的风险测量,要求个人估计特定行动的风险.
  • 这些措施对于了解风险感知对预防工作和行为改变的影响至关重要.

研究的目的:

  • 评估风险感知指标中的有条件措辞的潜在缺点.
  • 要确定有条件的措辞是否导致高估了感知到的风险和预期的预防行为之间的关系.

主要方法:

  • 从亚马逊的MTurk进行了一项在线实验,其中有750名美国参与者.
  • 参与者收到了关于一种不熟悉的真菌病的信息,并被随机分配到三个条件之一.
  • 评估了风险感知和接种疫苗的决定,其中两个条件使用了有条件的措辞 (如果没有接种疫苗,风险) 和一个作为无条件的基准.

主要成果:

  • 感知风险和预防决策之间的观察到的关系在与无条件基准相比,在有条件的措辞条件中被夸大了.
  • 这种通货膨胀发生在参与者在做出预防决定后提供风险估计时.

结论:

  • 风险感知问题中的有条件措辞可能会导致高估感知风险对预防决策的影响.
  • 尽管存在潜在的偏见,但条件措辞的影响很小,其测量效益表明继续在研究中使用.
  • 需要进一步的研究来确定这种偏见影响最明显的条件.
