Memory for the Experience of Donating Blood: Just How Bad Was It?

A field experiment investigated the accuracy of blood donor's memory for the emotions they experienced during blood donation. Compared to what they reported at the time of donation, the donors remembered a greater contrast between predonation and postdonation emotions. The donors also remembered experiencing more anxiety than they actually did. The bias in memory was especially pronounced among relatively inexperienced donors who had not been asked to report on their emotion prior to their actual donations. The memory boas was also related to donors' attitudes at the time of recall. Donors' intentions to donate blood again were reliably predicted by a combination of attitude and emotion measures. Discussion considers a potential intervention for improving donor return rates.     

Ask and You Shall be Given: Request Size and Donations to a Good Cause1

In an attempt to replicate the findings reported in this Journal by Weyant and Smith (1987), members or recent donors to a Canadian civil liberties organization were asked to donate money under one of three conditions: (a) In the control condition, they were simply asked for a donation; (b) in the “smaller request” condition, they were asked to make a donation, but amounts of Canadian $30 to $100 were suggested; and (c) in the “larger request” condition, amounts of $50 to $250 were suggested. Unlike the Weyant and Smith studies, we found no difference in the proportion of respondents making a donation, but significant differences in the size of the donations made by those making donations. In our study, the most effective way of getting large donations was to ask for a large amount. It was suggested that the most likely explanations for the differences in the results of the two studies were the following: First, our target population were previous donors to the organization, whereas those in the Weyant and Smith studies were not likely to have been. Previous research suggests that those who had been donors previously are influenced, positively, by requests for a specific large donation, whereas those not previously approached are, if anything, negatively influenced. Second, our “larger request” appears to be within a plausible range for donations, whereas the larger request in the Weyant and Smith study may have been seen as being outside of the plausible range. In any case, however, we would recommend caution in drawing a conclusion about the most effective request size to encourage people to donate money to charity.     

The role of identity in how whole‐blood donors reflect on and construct their future as a plasma donor

In the context of decreased demand for whole blood and increased demand for plasma‐derived products, donors in Australia are increasingly being asked to convert from whole‐blood to plasmapheresis donations. Plasmapheresis is a different type of donation to whole blood as the process takes longer and can be engaged in more frequently. What is unknown is whether whole‐blood donors view donating plasma as consistent with their donor identity and how they respond to the possibility of donating more frequently. To explore this, we undertook semistructured telephone interviews with 26 whole‐blood donors who had recently made their first plasma donation. Findings indicated that whereas donating plasma was viewed as a bigger ask than donating whole blood, the former was viewed as consistent with their identity as a donor because both behaviours were seen to benefit others and self and were located within the same institutional context. Donating plasma was an opportunity for donors to enhance their self‐concept as an altruistic giver. When contemplating their future donation behaviour, donors considered how their donor identity would fit alongside other salient roles. These findings have implications for how institutions can position their request of existing donors to give a different gift.     

Asking questions changes behavior: mere measurement effects on frequency of blood donation.

OBJECTIVE: This research examined the impact of completing a questionnaire about blood donation on subsequent donation behavior among a large sample of experienced blood donors. DESIGN: Participants (N=4672) were randomly assigned to an experimental condition that received a postal questionnaire measuring cognitions about donation or a control condition that did not receive a questionnaire. MAIN OUTCOME MEASURES: Number of registrations at blood drives and number of successful blood donations were assessed using objective records both 6 months and 12 months later. RESULTS: Findings indicated that, compared to control participants, the mean frequency of number of registrations at blood drives among participants in the experimental group was 8.6% greater at 6 months (p<.0.007), and was 6.4% greater at 12 months (p<.035). Significant effects were also observed for successful blood donations at 6 months (p<.001) and 12 months (p<.004). CONCLUSION: These findings provide the first evidence that the mere measurement is relevant to promoting consequential health behaviors. Implications of the research for intervention evaluation are discussed.     

THE PERILS OF PARTICIPATION: EFFECTS OF CHOICE OF TRAINING ON TRAINEE MOTIVATION AND LEARNING

This study presents an empirical test of the effects of trainee choice of training on subsequent motivation and learning. 207 trainees were randomly assigned to one of three conditions: (a) no choice of training; (b) choice of training–but choice not received; (c) choice of training–with choice received. A pilot study was used to create a unique training context whereby trainees could be differentiated on the three conditions of choice, while all ultimately received the identical training module. Results indicated that, after controlling for cognitive ability, those trainees having a choice of training did have greater motivation to learn, provided they were ultimately given the training of their choice. On the other hand, trainees allowed to choose but whose choice was not the training module subsequently delivered were less motivated and learned less than those not asked to participate in the choice of training at all. These findings suggest that, in an organizational training context, there may be some "perils of participation." Implications for future research and practice are discussed.     

Accountability and judgment processes in a personality prediction task

In this experiment, we investigated the impact of accountability--social pressures to justify one's views to others--on cognitive processing in a personality-prediction task. Subjects were presented with the responses of actual test-takers to 16 items from Jackson's Personality Research Form (PRF) and asked to predict how these individuals responded to an additional set of 16 items from the same test. Subjects were assigned to a no-accountability condition (they learned that all of their responses would be anonymous), a preexposure-accountability condition (they learned of the need to justify their responses before seeing the test-takers' PRF responses), and a postexposure-accountability condition (they learned of the need to justify their responses after seeing the test-takers' PRF responses). Preexposure-accountability subjects reported more integratively complex impressions of test-takers, made more accurate behavioral predictions, and reported more appropriate levels of confidence in their predictions than did either no-accountability or postexposure-accountability subjects. We conclude by considering possible psychological mediators of these effects as well as the broader theoretical implications of the findings for the development of contingency models of judgment and choice.     

Making Connections in Math: Activating a Prior Knowledge Analogue Matters for Learning

This study investigated analogical transfer of conceptual structure from a prior-knowledge domain to support learning in a new domain of mathematics: division by fractions. Before a procedural lesson on division by fractions, fifth and sixth graders practiced with a surface analogue (other operations on fractions) or a structural analogue (whole number division). During the lesson, half of the children were also asked to link the prior-knowledge analogue they had practiced to fraction division. As expected, participants learned the taught procedure for fraction division equally well, regardless of condition. However, among those who were not asked to link during the lesson, participants who practiced with the structurally similar analogue gained more conceptual knowledge of fraction division than did those who practiced with the surface-similar analogue. There was no difference in conceptual learning between the two groups of participants who were asked to link; both groups performed less well than did participants who practiced with the structural analogue and were not asked to link. These findings suggest that learning is supported by activating a conceptually relevant prior-knowledge analogue. However, unguided linking to previously learned problems may result in negative transfer and misconceptions about the structure of the target domain. This experiment has practical implications for mathematics instruction and curricular sequencing.     

Door-in-the-Face Technique and Delay to Fulfill the Final Request: An Evaluation With a Request to Give Blood

We tested the Door-in-the-Face technique (DITF) on blood donation with a delay between the acceptance of the request and the real possibility of complying with it. University students were solicited to give blood during a special one-day drive. After the refusal to participate in a long-term donor program, participants were asked for a one unit blood donation. In the control condition, only the latter request was addressed. The participants were either solicited two or three hours before the blood drive (delay) or during the blood drive (no delay). Results showed the DITF technique to be associated with greater verbal compliance with the request. However, the DITF technique with no delay was associated with greater behavioral compliance than were both of the control conditions and the DITF with a delay condition.     

Analysis of effects of distribution of practice in learning and retention of a continuous and a discrete skill presented on a computer

This investigation examined the effects of distributed and massed practice on the learning and retention of a discrete computerized skill (Exp. 1) and a continuous computerized skill (Exp. 2). 40 men were randomly assigned to one of four groups, of which two groups took part in Exp. 1 and two groups in Exp. 2. Performance was assessed at various points during acquisition and then on 8 retention tests conducted at varying times after acquisition. Learning curves for practice were highly similar for the two conditions. Participants in the distributed-practice group performed significantly better than those in the massed-practice group at the end of practice on both the discrete and continuous skills. However, participants in the distributed-practice group performed significantly more poorly on retention during 24 hr. and after acquisition. Participants in the massed-practice condition performed significantly better on retention tests than did those who learned in the distributed-practice condition.     

Effects of disclosure of traumatic events on illness behavior among psychiatric prison inmates

To assess the health effects of writing about traumatic events in a clinical population, 98 psychiatric prison inmates were randomly assigned to 1 of 3 conditions in which they were asked to write about their deepest thoughts and feelings surrounding upsetting experiences (trauma writing condition), write about trivial topics (trivial writing control), or go about their daily routine without writing (no-writing control). Both writing groups wrote for 20 min per day for 3 consecutive days. Participants in the trauma condition reported experiencing more physical symptoms subsequent to the intervention relative to those in the other conditions. Despite this, controlling for prewriting infirmary visits, sex offenders in the trauma writing condition decreased their postwriting infirmary visits. These results are congruent with predictions based on stigmatization and inhibition.     

陌生他人在场及其行为对个体道德伪善的影响

道德伪善既有印象管理或欺人的一面, 也有自欺的一面。道德伪善的影响因素众多, 而人际层面的影响因素则少有研究。本研究采用实验的方法, 以大学生为被试, 设置捐款情境, 探讨单个陌生他人在场及其真善/伪善行为能否抑制个体的道德伪善。结果表明：陌生他人单纯在场或做出伪善行为都不能抑制捐款情境中个体的道德伪善, 而在场陌生他人的真善行为可以有效抑制捐款情境中个体的道德伪善。     

The effects of behavior rehearsal and feedback on the acquisition of problem-solving skills in distressed and nondistressed couples

Couples who were paid to participate in an experimental marital enrichment program were randomly assigned to one of four treatment conditions or to a control group. All groups received training in solving marital problems, but the groups differed according to how they were trained; some received feedback (FB) on their previous taped performances, some had the opportunity to practice the skills suggested by the therapist (BR), some had both (complete treatment), and some simply were presented with instructions. Changes in problem-solving skills were assessed by behavioral observations of the frequency of positive problem-solving behavior before and after treatment, and global ratings of problem-solving effectiveness made by trained raters. In general, the complete treatment condition produced greater changes from pre- to post-test than any other condition. Couples in this condition showed significantly greater increases in positive behavior than any other group, and on global ratings of problem-solving skills they evidenced the greatest improvement, although on this measure they did not improve significantly more than BR couples.     

Psychophysiological and cognitive responses to stressful stimuli in subjects practicing progressive relaxation and clinically standardized meditation

Thirty-six volunteer subjects were assigned to one of three conditions: progressive relaxation, clinically standardized meditation, or a waiting list control group asked to relax daily (without specific instruction). Subjects were given paper and pencil tests two times, separated by 5 weeks during which time the two treatment groups received 4 weekly sessions of group training. All subjects were tested in the psychophysiology laboratory at the end of the 5-week period, during which time they were exposed to 5 very loud tones. While relaxing as deeply as possible using the techniques they had learned and anticipating the loud tones, the meditation group exhibited higher heart rates and higher integrated frontalis EMG activity, but they also showed greater cardiac decelerations following each tone, more frontal alpha, and fewer symptoms of cognitive anxiety than the other two groups. The relaxation group reported more sensations of muscular relaxation than the other groups, but also some symptoms of hyperventilation. The results are generally consistent with Davidson and Schwartz's (1976) categorization of meditation as a ‘cognitive’ technique, and suggest that frontal EEG alpha may be a physiological marker for the absence of cognitive anxiety. Physiological findings also support Goleman and Schwartz's (1976) suggestion that meditation prepares people to cope with stress.     

Do Computer-Based Games Facilitate Knowledge Acquisition and Retention?

This study investigated the effects of a gaming approach on knowledge acquisition and retention in military trainees. Three groups of trainees were presented with subject matter in paper-based prose form (text), paper-based question-and-answer form (test), or computer-based gaming form (game). These conditions were selected to investigate potential benefits of computer-based gaming over traditional paper-and-pencil media in terms of trainee performance and reaction. Results showed that participants assigned to the game condition scored significantly higher on a retention test com- pared to pretest performance. Furthermore, participants assigned to the game condition scored significantly higher on a retention test than did participants assigned to the text condition. Participants assigned to the test and text conditions showed no benefit from training in performance at the retention test. In addition, participants assigned to the game condition rated the training they received as more enjoyable and more effective than did those assigned to the other 2 conditions. Results are discussed in terms of the effectiveness of computer-based games for military training applications.     

Autobiographical memory and autobiographical narrative of a staged event: The influence of the listener

The purpose of the present study was to investigate the role of narration and listening conditions in autobiographical memory of a staged event. Eighty young adults were recruited for the present research. First, they were interviewed on current issues (staged event). Second, they were asked to complete a memory questionnaire about the content of the interview. Then, they were assigned to three retrieval conditions: narration to an empathic listener, narration to a detached listener, and retrieving thinking silently about the event. Finally, 1 week later, the participants were asked to complete the memory questionnaire again to assess the influence of narration and listening conditions on memory. The results show that the experimental conditions significantly influenced the memory trend for a staged event. The emphatic listening condition promoted memory significantly more than did the other two conditions. The authors interpret these results in terms of the theory of narrativization.     

Common-sense models of illness: the example of hypertension

Our premise was that actions taken to reduce health risks are guided by the actor's subjective or common-sense constructions of the health threat. We hypothesized that illness threats are represented by their labels and symptoms (their identity), their causes, consequences, and duration. These attributes are represented at two levels: as concrete, immediately perceptible events and as abstract ideas. Both levels guide coping behavior. We interviewed 230 patients about hypertension, presumably an asymptomatic condition. When asked if they could monitor blood pressure changes, 46% of 50 nonhypertensive, clinic control cases said yes, as did 71% of 65 patients new to treatment, 92% of 50 patients in continuing treatment, and 94% of 65 re-entry patients, who had previously quit and returned to treatment. Patients in the continuing treatment group, who believed the treatment had beneficial effects upon their symptoms, reported complying with medication and were more likely to have their blood pressure controlled. Patients new to treatment were likely to drop out of treatment if: they had reported symptoms to the practitioner at the first treatment session, or they construed the disease and treatment to be acute. The data suggest that patients develop implicit models or beliefs about disease threats, which guide their treatment behavior, and that the initially most common model of high blood pressure is based on prior acute, symptomatic conditions.     

大学生网络捐助的影响因素:求助者特征的视角

以往关于捐助的心理学研究主要聚焦于现实环境中的捐助行为,以及捐助者自身特点对捐助的影响,网络环境、求助者特征对捐助影响的研究较少。本研究以大学生为被试,比较不同信息发布者情境中,网络与现实中捐助的意愿,并确定求助者的身份特征和求助信息特征对网络捐助的影响。结果发现,在捐助意愿和捐助金额方面,网络渠道高于现实渠道、熟人发布高于陌生人发布;当求助者与捐助者同为大学生时,捐助者对求助者的理性求助信息比情绪性求助信息有更强的捐助意愿和更多捐助金额。以上结果与大学生网络社会支持水平较高、处理网络信息能力较强有关。

不确定性决策违背“确定事件原则”的心理机制再探

不确定性决策违背＂确定事件原则＂的心理机制再探从决策理由切入,在现实情境中考察了违背确定事件原则（sure-thing principle）的心理机制,检验了基于理由（reason-based）的假设。研究结果表明,违背确定事件原则的被试在不确定条件下知觉到的理由冲突程度显著高于遵循确定事件原则的被试在不确定条件下知觉到的理由冲突程度;违背确定事件原则的被试在不确定条件下知觉到的理由清晰程度显著低于其在两种确定条件下知觉到的理由清晰程度,而遵循确定事件原则的被试在不确定条件下知觉到的理由清晰程度则介于其在两种确定条件下知觉到的理由清晰程度之间。研究结果支持了基于理由的假设。     

The Logical Levels of Complementary,Symmetrical, and Parallel Interaction Classes in Family Dyads

It was postulated that the parallel interaction class is a higher logical order than complementary and symmetrical interaction, which appear to be of the same logical type. Father-mother, father-child, and mother-child dyads of 48 families were categorized into complementary, symmetrical, and parallel classes using the Relationship Styles Inventory. Each of the dyads in these three categories was then randomly assigned to one of two experimental conditions in which they jointly resolved a moral dilemma. In one condition, the dyads were asked to follow complementary rules, while in the second condition they were instructed to follow symmetrical rules. Results indicated that parallel dyads adjusted to both the complementary and symmetrical conditions, whereas symmetrical and complementary dyads did not successfully accommodate rules outside their own class. The implications in terms of therapeutic intervention and further research are discussed.
