H567/03 Section B Option 3 - Lord (1994) and motivating conservation

Message, source and aim

Lord (1994), Motivating recycling behavior: A quasiexperimental investigation of message and source strategies, investigated whether message framing and source affected recycling beliefs, attitudes and behaviour. The topic asks why conservation messages may change opinions without producing the same change in action.

Positive framing stressed benefits of recycling, such as environmental protection and community savings. Negative framing stressed risks or losses from not recycling, including environmental and social consequences. Both supplied reminders about items and collection. Framing concerns what is emphasised; source concerns who appears to communicate it.

Sources were a commercial advertisement for a fictitious environmentally concerned company, a news article presented as coming from a local publication, or a personal letter signed by a student acquaintance. These could differ in credibility, attention and perceived personal expectation. Such mechanisms are plausible interpretations; the study did not directly measure every possible relationship or mental process.

The cognitive area explains interpretation of benefits and consequences. The social area explains why a personal source may have a different impact from an advertisement. Individuals still choose how to respond, so an influence on average behaviour does not demonstrate inevitable compliance or remove agency.

Design, sample and materials

The field study involved 140 households in metropolitan Buffalo, New York, where curbside recycling was available. Two message frames crossed with three sources produced six message conditions. A no-message control made seven conditions, with 20 households in each: $3\times2+1=7$, and $7\times20=140$.

This was a quasi-experimental investigation: source and framing were deliberately varied, but household recruitment and allocation did not provide unrestricted individual random assignment. Student assistants from a marketing course recruited and observed households. Quota instructions sought comparable characteristics; personal-letter recipients had to be acquaintances. This relationship requirement could introduce differences in addition to the message itself.

Inner-city households were excluded for observer safety, contributing to a more advantaged sample. Among questionnaire respondents, 57% were women, ages ranged from 19 to 65 and mean age was 34.9; median education was some college. Reported demographic profiles did not differ significantly across conditions, but this does not prove equivalence on all motivation or social relationships. Household observations and questionnaire respondents should not be treated as interchangeable units.

Attitudes were measured through four seven-point semantic-differential judgements, such as favourable versus unfavourable evaluation. Belief measures assessed perceived truth of statements; message-attitude items and demographics were also collected. Observed recycling recorded counts of items and categories, not weight, carbon saved or correct downstream processing.

Household procedure and outcomes

On the first weekly collection, assistants discreetly recorded materials placed out for recycling, including item quantities and categories such as newspapers, cardboard and glass. The following day the relevant message was left at the front door, without a face-to-face persuasive conversation. Control households received no message.

On the next collection, recycling was observed again using the same approach. The following day a questionnaire was given to the adult chiefly responsible for sorting or handling household waste. This was the first face-to-face contact in the procedure. Responses were placed in sealed, unidentified envelopes before data entry, protecting anonymity.

The before-and-after observations allow a change in actual recycling to be examined, rather than assuming a favourable attitude demonstrates action. The no-message condition helps judge whether changes reflect receiving a message rather than only a general change between collection days. However, two collections give limited evidence about persistence, and the materials available for disposal can vary naturally between weeks.

Standardised recording categories support reliability, but observers still need consistent rules about what counts as an item. A bundle of papers and a bottle are not equivalent in mass. Discreet observation also raises a privacy and consent question even though recycling was placed out for collection; apparent public visibility is not a substitute for considering ethical rights.

Findings: attitude and action

Message conditions pooled together produced more favourable recycling attitudes than the control: reported means were 2.19 versus 1.72 on the study's attitude measure. Positive messages produced stronger agreement with message beliefs than negative messages: 5.71 for positive, 3.20 for negative and 2.50 for control. Negative-message belief scores were not significantly different from control.
