Rm. Perrine et S. Heather, Effects of picture and even-a-penny-will-help appeals on anonymous donations to charity, PSYCHOL REP, 86(2), 2000, pp. 551-559
The present research explored the effectiveness of a picture and the phrase
"even a penny will help" on contributions to charity. Two experiments were
conducted, one in the laboratory and one in the field. Tn both experiments
the manipulation of a pleasant picture and the phrase created four types o
f signs: (1) picture-no phrase, (2) phrase-no picture, (3) picture-phrase,
and (4) no picture-no phrase. In the field experiment patrons of local busi
ness anonymously put money in a donation box that displayed one of the four
signs. In the laboratory experiment, 129 undergraduate students were rando
mly assigned to view one of the four signs placed on a donation box for a l
ocal charity. Analyses for both studies showed that more money was donated
when the boxes displayed pictures. The phrase "even a penny will help" had
no significant effect on donations.
