Q

Impact on target equation

A

Impact on target = f(strength x immediacy x number of sources)

Or

Impact on target = f(SIN)

Q

Define immediacy in terms of social impact theory

A

Q

Explain the multiplicative effect (light bulb)

A

• Strength: the power of the lightbulb
—> to strengthen: increase voltage

• Immediacy: how close the lightbulb is, delay between pressing the button and light turning on
—> to increase immediacy: can physically bring light closer into the room, remove the delay (buy a new lightbulb)

• Number: the number of lightbulbs
—> to increase number: buy more lightbulbs

Q

What is the divisional effect?

A

Divisional effects (division of impact) suggests that social impact is reduces if there are more targets than there are sources, with the impact to each individual target being reduced

E.g.
• teacher instructing you alone = stronger impact, impact is given all to you
• teacher instructing class = weak impact, impact is divided between each person

Q

Evaluate the strength of Social impact theory (with supportive evidence)

A

A strength of social impact theory is the evidence from Sedikides and Jackson (1990), because it tests the components of the theory and has results that demonstrate the effects of them.

They found that the strength of the source, immediacy and number all affected obedience,
alongside seeing the divisional effect. The study took place in a zoo, and when customers were instructed to move, the rate of compliance decreased if the group of targets increased.

This study demonstrates that multiple aspects of social impact theory have been shown to influence obedience in a realistic setting which makes the theory a credible explanation of why people obey authority.

Q

Evaluate the weakness of social impact theory (with supportive evidence)

A

A weakness of social impact theory is there is contradictory evidence to suggest the psychosocial forces are different.

Hofling et al (1966) counters social impact theory as 21/22 nurses obeyed orders to overdose a patient on a medication based on orders from a doctor delivered over the phone. The doctor was not present, so the immediacy was low, however, the majority of the nurses still obeyed.

This suggests that immediacy may not play such an important role, or have as great an impact on obedience as proposed by the social impact theory, discrediting the theory
