Framing Effects

7.9K
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...

Frames01:30

Frames

825
Frames are essential components of various mechanical and structural systems used daily. These structures are known for their stability and ability to bear heavy loads. A frame is constructed using two-force and multi-force members, interconnected using pin joints. In contrast, trusses are made entirely of two-force members.
Frames are versatile and widely used in various applications such as structural supports for beams and columns, automobile chassis construction, and in the construction...

Gain01:15

Gain

379
Gain and phase shift are properties of linear circuits that describe the effect a circuit has on a sinusoidal input voltage or current. The circuit's behavior that contains reactive elements will depend on the frequency of the input sinusoid. As a result, it is observed that the gain and phase shift will all be frequency functions.
Gain:
Suppose Vin is the input and Vout is the output signal to a circuit.

Consider a jib crane with an external load suspended from the pulley. The dimensions of the crane members are shown in the figure. A systematic analysis of the frame structure is required to determine the reaction forces at the pin joints, assuming that the pulleys are frictionless.

Consider a hydraulic hoist supporting a load of 1 kN. Assuming a simplified schematic representation of this frame structure, the force acting on BD and BF members can be determined.

Line Loss01:10

Line Loss

517
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

Summary

Gain frames may backfire when communicating health risks, especially with low message doses. Increasing message dose or using loss frames can improve intentions for physical activity.

Area of Science:

  • Health Communication
  • Psychology
  • Behavioral Science

Background:

  • Framing effects in health risk communication yield mixed results.
  • Reactance and message dose are potential moderators/mediators of framing effects.

Purpose of the Study:

  • To examine reactance as a mediator and message dose as a moderator of loss/gain framing effects on physical activity intentions.

Main Methods:

  • Adults (N=1,039) were exposed to framed messages about physical activity in varying doses.
  • Measures included threat to freedom, reactance, and intentions to exercise.

Main Results:

  • Gain frames induced greater threat to freedom and reactance than loss frames.
  • Message dose significantly influenced intentions, with one-dose messages showing lower intentions than four-dose messages.
  • Significant frame × dose interactions were observed; one-dose gain frames reduced exercise intentions more than loss frames.

Conclusions:

  • Gain frames can be less persuasive than loss frames due to increased reactance, particularly at low message doses.
  • Optimizing health messages requires considering both message framing and dosage to avoid unintended reactance and promote behavioral intentions.
