Tabacco deprivation: The foot-in-the-door technique versus the low-ball technique

The present experiment was aimed at comparing the efficiency of the foot-in-the-door technique (Freedman and Fraser, 1966) to that of the low-ball technique (Cialdini Bassett, Cacioppo and Miller, 1978). Subjects were requested to abstain from smoking for 18 hours. The results demonstrated the superiority of the low-ball technique. An original method of operationalizing the low-ball technique (the use of intermediate behaviours) is presented herein.     

Compliance without pressure: Some further data on the foot-in-the-door technique

A replication of the Freedman and Fraser (1966) “foot-in-the-door” technique was attempted in which subjects were exposed to one of two prior requests and were then asked to comply with a larger request. The results showed that subjects receiving prior requests complied with the larger request significantly more often than did control subjects. The mechanism by which the technique operates was discussed.     

Appearance (ethnic origin) of requester affects the foot-in-the-door technique

A study was designed to examine the effect of the appearance of the requester within one of the variants of the foot-in-the-door paradigm, that is, the foot-in-the-door with implicit demand described by Uranowitz in 1975. A confederate (Black vs. Blanc vs. Beur2) approached the participant in a park and presented a small request. Three steps further, the confederate "accidentally" dropped 30 sheets of paper. Whether or not the participant helped the confederate in retrieving the dropped pamphlets was recorded as the implicit dependent variable. The foot-in-the-door effect was observed solely when the requester was Blanc. This result shows that the foot-in-the-door effect is not as strong as the literature suggests and undermines the usual interpretations of the foot-in-the-door effect in terms of self-perception and commitment.     

Occlusion as a depth cue in the Wheatstone-Panum limiting case.

We examined the hypothesis (Ono & Wade, 1985) that occlusion of far stimuli by a near one on the same visual line can operate as a depth cue in stereograms containing different numbers of targets in the two eyes. By controlling eye positions, we created conditions in which the visual system could interpret the retinal images as originating from stimuli on the visual axis of one eye and also created other conditions in which the origin of the retinal images was ambiguous. In Experiment 1, we presented two lines to one eye and a single line to the other eye. When the image of the line on the temporal side of the line pair on one retina fused with the image of the single line on the other retina, the nonfused line appeared farther away more often than it did when the image on the nasal side fused. In Experiment 2, we used two differently shaped stimuli. In the condition in which the nonfused stimulus represented an object being occluded, it appeared farther away more often than in the four conditions in which it did not. In Experiment 3, we extended the idea to three different objects. When the middle of the three images fused with the single image, the nonfused stimulus appeared farther when it could be interpreted as being occluded than when it could not. In the condition in which the most temporal image fused with the single image, the nonfused stimuli appeared farther than in the condition in which the most nasal one fused. The results supported the hypothesis that occlusion plays a role in depth perception in the Wheatstone-Panum limiting case.     

Wheatstone-Panum limiting case: occlusion, camouflage, and vergence-induced disparity cues.

We examined effects of binocular occlusion, binocular camouflage, and vergence-induced disparity cues on the perceived depth between two objects when two stimuli are presented to one eye and a single stimulus to the other (Wheatstone-Panum limiting case). The perceived order and magnitude of the depth were examined in two experimental conditions: (1) The stimulus was presented on the temporal side (occlusion condition) and (2) the nasal side (camouflage condition) of the stimulus pair on one retina so as to fuse with the single stimulus on the other retina. In both conditions, the separation between the stimulus pair presented to one eye was systematically varied. Experiment 1, with 16 observers, showed that the fused object was seen in front of the nonfused object in the occlusion condition and was seen at the same distance as the nonfused object in the camouflage condition. The perceived depth between the two objects was constant and did not depend on the separation of the stimulus pair presented to one eye. Experiment 2, with 45 observers, showed that the disparity induced by vergence mainly determined the perceived depth, and the depth magnitude increased as the separation of the stimulus pair was made wider. The results suggest that (1) occlusion provides depth-order information but not depth-magnitude information, (2) camouflage provides neither depth-order nor depth-magnitude information, and (3) vergence-induced disparity provides both order and magnitude information.

Blood donation is an act of benevolence rather than altruism.

OBJECTIVES: Blood donation is described as an archetypal altruistic behavior, and recruitment/retention campaigns emphasize altruism. Here, a benevolence hypothesis for blood donation (both the donor and recipient benefit) rather than the altruism hypothesis (only the recipient gains) is proposed. DESIGN: Three United Kingdom-based studies contrasted benevolence and altruism: (a) a 6-month prospective study of blood donor behavior (Study 1: N = 957), (b) a cross-sectional study of blood donors' intentions (Study 2: N = 333), and (c) an experimental study examining the effect of benevolent and altruistic messages on willingness to help across high- and low-cost helping behaviors for committed and noncommitted blood donors (Study 3: N = 200). MAIN OUTCOME: Donor behavior and intentions-willingness. MEASURES: Beliefs in personal and societal benefit (Time 1) and actual donations (Time 2) were assessed in Study 1; beliefs in benevolence, altruism, hedonism, and kinship along with donation intentions were assessed in Study 2; and empathy, donor commitment, and willingness to donate blood, money, fund-raise, and staff a telephone helpline were assessed in Study 3. RESULTS: Beliefs in personal rather than societal benefit predicted actual future donation. A path model showed that only beliefs in benevolence were associated with intentions to donate. Committed blood donors were more willing to donate blood when exposed to a benevolent message rather than an altruistic one. This effect was not observed for other forms of helping. CONCLUSIONS: The benevolence hypothesis is supported, suggesting that blood donor motivation is partly selfish. Blood donation campaigns should focus on benevolent rather than purely altruistic messages.

Non-heart-beating organ donation: a reply to Campbell and Weber.

In the preceding commentary, Campbell and Weber raise two valid and important issues concerning non-heart-beating organ donation (NHBOD). First, because the procedure links withdrawal of life support and the potential for subsequent organ donation, the desire for organs may create a situation in which care of the dying individual has relatively less importance and the dying may receive suboptimal care. Second, even if concerns about care of the dying were dealt with adequately, there will not be enough non-heart-beating donors to significantly decrease the organ shortage that exists, making the procedure not worth the risk. We agree that attention to the important details of caring for the dying are, and must be, the primary concern of all health care workers caring for those individuals. Ensuring the patients' comfort, dignity, and autonomy, and providing for family and social support are the mainstays of this care. All policies for NHBOD should clearly support and mandate these concepts. Regarding the second concern, we agree that NHBOD is currently rare; however, evidence is increasing that this type of donation has great potential. Continued growth of the practice in this country will depend largely on public acceptance, which we believe will be directly influenced by whether the public perceives that care of the dying is not compromised by this procedure.     

Organ donation: a communitarian approach

Recently, various suggestions have been made to respond to the increasingly great shortage of organs by paying for them. Because of the undesirable side effects of such approaches (commodification, injustice, and costs), a communitarian approach should be tried first. A communitarian approach to the problem of organ shortage entails changing the moral culture so that members of society will recognize that donating one's organs, once they are no longer of use to the donor, is the moral (right) thing to do. This approach requires much greater and deeper efforts than sharing information and making public service announcements. It entails a moral dialogue, in which the public is engaged, leading to a change in what people expect from one another. Among the devices that could help change the moral culture are a public statement, endorsed by community members and leaders, that expresses the community sense that donation "is what a good person does" and a community-specific web page that lists those who have made the commitment. A change in law so that a person's wishes in the matter are recognized as final and binding are also desired. This position paper deals only with cadaver organs and not living donors.     

Double fusion does not occur in Panum's limiting case: evidence from orientation disparity.

When two lines of different orientations are combined in regular stereograms, the orientation of the resulting line is different from those of the monocular lines. In this study we investigate the percept elicited by orientation disparity in Panum's limiting case. A variant of Panum's limiting case was designed to include orientation disparity. The single line in one half-image tilted leftwards. One of the double lines in the other half-image was parallel to the single line, while the other one tilted rightwards with obliquity one third that of the single line. In this stimulus configuration, if the single line in one half-image fuses with both lines in the other half-image at the same time, both of the two lines perceived after fusion should tilt leftwards. If double fusion does not happen, the two lines should tilt leftwards and rightwards respectively. The results of this study are in agreement with the latter prediction, which implies that double fusion does not occur in this variant of Panum's limiting case.     

An application of the foot in the door technique to organ donation

The extent to which the size of an initial request related to organ donation could be reduced when using the foot-in-the-door technique was investigated. After being asked to comply with an initial request to complete a questionnaire related to organ donation having either 5, 10, 15, or 20 items or not being asked to complete the questionnaire, subjects indicated their willingness to become an organ donor. In addition to replicating earlier research, the results indicated that the original 20-item questionnaire could be reduced to five items without losing its effectiveness to increase willingness to become an organ donor when compared to the no-request condition. The implications of the foot-in-the-door technique for medical volunteering in general and suggestions for future research are also discussed.     

Play therapy as a family restructuring technique: A case illustration

This paper presents a general treatment approach which uses play to integrate individual and family psychotherapy when working with young children as identified patients. Play therapy techniques are explored with regard to their potential impact upon a family system. Perspectives on concurrent and conjoint family oriented treatment using play are discussed with a focus upon achieving both individual and family system growth.
