Two experiments examined the role of intentions in people's allocation of time to everyday activities (e.g., talcing a shower, running for exercise). In Experiment 1 32 subjects rated their intentions of, preferences for, and perceived control over performance of 10 activities at different frequencies during the following month. In Experiment 2 another 36 subjects performed the same ratings for the following week, then returned after that week to report how frequently they had been engaged in the activities. The results of both experiments showed that either the ratings of preference, of perceived control, or both combined linearly, predicted the intentions. However, intentions did not predict performance particularly well. This probably reflected (1) that some activities are performed routinely without intentions being formed; (2) that intentions to perform some other, more impulsively timed activities are formed late when appropriate actual situations are encountered; and (3) that for still other activities intentions are formed but not maintained.  相似文献

This study examined age differences in the accessibility of a single pool of naturally occurring intentions both before and after completion. Following Maylor, Darby, and Della Sala (2000), accessibility was measured in terms of the number of activities generated in a 4‐minute activity fluency task. Each participant undertook two such tasks. A prospective task in which they generated activities intended for completion during the following week and a retrospective task, 1 week later, in which they generated activities carried out over the previous week. In a partial replication of Maylor et al.'s findings, young, but not healthy older, adults generated more to‐be‐completed intentions than completed ones, demonstrating an intention‐superiority effect (ISE) for everyday activities. The absence of an ISE for older adults appeared to reflect the reduced accessibility of intentions prior to completion, rather than the impaired inhibition of fulfilled intentions. Moreover, both groups showed greater inaccessibility of completed than intended activities, thus demonstrating an intention‐completion effect for naturally occurring intentions that is preserved in healthy ageing (cf. Marsh, Hicks, & Bink, 1998). Despite showing a reduced accessibility of intended activities, older adults reported having completed a greater proportion of their intentions during the week than young adults. Moreover, there was a correlation between the ability to access intentions and the proportion of intentions completed only for young adults. These observations suggest that older adults' everyday prospective memory performance may be relatively less dependent on intention accessibility and more dependent on other factors. While there was no age difference in the reported use and effectiveness of external retrieval aids, older adults demonstrated a greater level of temporal organization in the production of their intentions in the fluency task. This is consistent with the possibility that older adults may have more structured daily lives and may be able to use information about the sequence of ongoing events to support superior everyday prospective remembering.  相似文献

The aim of the present studies was to investigate whether age‐related improvement found in naturalistic but experimenter‐given prospective memory (PM) tasks can be generalized to real‐life intentions. In Study 1, younger, middle‐aged, and older adults generated a list of intended activities for the following week; one week later they marked the tasks that they had performed. The participants were also asked to rate the importance of each listed intention and to describe the circumstances of completion that were already known to them. We found that, compared with younger adults, older adults attributed a higher degree of importance to their intentions and had the circumstances of their completion better planned. However, the age‐related benefit in the PM performance for all listed intentions was not present for the very important and well‐planned tasks. In Study 2 we manipulated whether younger adults engaged or not in the detailed planning of when their intentions could be completed. It was demonstrated that younger adults who had to perform detailed planning completed their intended activities more often than those who did not plan for their intentions. The results support explanations of the age‐related benefit in everyday PM that highlight the role of importance and planning.  相似文献

In everyday life, we often use external artefacts such as diaries to help us remember intended behaviours. In addition, we commonly manipulate our environment, for example by placing reminders in noticeable places. Yet strategic offloading of intentions to the external environment is not typically permitted in laboratory tasks examining memory for delayed intentions. What factors influence our use of such strategies, and what behavioural consequences do they have? This article describes four online experiments (N?=?1196) examining a novel web-based task in which participants hold intentions for brief periods, with the option to strategically externalize these intentions by creating a reminder. This task significantly predicted participants' fulfilment of a naturalistic intention embedded within their everyday activities up to one week later (with greater predictive ability than more traditional prospective memory tasks, albeit with weak effect size). Setting external reminders improved performance, and it was more prevalent in older adults. Furthermore, participants set reminders adaptively, based on (a) memory load, and (b) the likelihood of distraction. These results suggest the importance of metacognitive processes in triggering intention offloading, which can increase the probability that intentions are eventually fulfilled.  相似文献

One hundred eleven college students participated in this two-session experiment designed to explore the origins of anti-nuclear war activism. In Session 1 participants completed questionnaires assessing a number of background characteristics and attitudes, the most important of which for this study's purpose was a measure of perceived political efficacy in the nuclear realm. One week later both the salience of the nuclear weapons issue and participants' sense of personalized risk were experimentally manipulated in a 2 × 2 × 2 (salience × risk × measured efficacy) design. Dependent measures were a behavioral intentions questionnaire and an actual opportunity to sign a petition which participants did not recognize as part of the experiment. High salience significantly increased both anti-nuclear war behavioral intentions and actual behavior as predicted. Individuals who felt highly efficacious were also significantly more likely to take action than others as predicted. A similar relation between efficacy and behavioral intentions was not found, although a salience by efficacy interaction was. Personalized risk influenced only behavioral intentions. Finally, the relative impact of these three variables and of other background and attitudinal variables measured in the first session was explored using regression techniques.  相似文献

Although increasing exercise and fitness has often been associated with positive health outcomes, infrequent exercise participation has remained a problem. Since two distinct motivational and volitional phases to goal pursuit have been proposed, a combined motivational (decision balance sheet, DBS) and volitional (implementation intentions) intervention was predicted to be more effective in increasing exercise behaviour than a control or either strategy alone. A total of 86 students were randomly assigned to one of the four conditions, and were all asked to try to exercise two more times a week than they currently did, over a four week period. Their fitness levels were measured through fitness tests conducted pre- and post-intervention. A priori orthogonal contrasts indicated that the experimental strategies produced a greater increase in exercise frequency and total time spent exercising per week and accordingly showed greater fitness improvements than the control group. Moreover, the volitional groups taken together produced greater increase in time spent exercising and a marginally greater improvement in frequency than the DBS alone. The combined intervention led to improvements in fitness and marginal increases in frequency over the implementation intention alone group. It is proposed that for the combined group the DBS may have aided recall of the implementation intention or increased commitment to it, as remembering and then acting on the plan, in the stated place and time, mediated the implementation intention–behaviour relationship. The combined intervention produced the greatest fitness improvements, indicating that this strategy can lead to important health benefits.  相似文献

This study compared activity-based intentions with event- and time-based intentions. Forty-five participants completed a laboratory session that tested activity-, event-, and time-based prospective memory. Participants were then asked to keep a record of their planned academic and work-related activities for 1 week. Results revealed a main effect of context such that participants were better at performing intentions in the naturalistic setting than in the laboratory. A strong trend of intention type showed that event-based tasks were more likely to be performed than activity- and time-based tasks. An interaction of context and intention type suggested that participants were significantly better at performing time-based tasks in the naturalistic setting than in the lab. Nearly half of the participants reported using simple memory aids such as alarm clocks, parent or friend reminders, or other external cues. Strikingly, very few reported using electronic devices to aid their memory for future intentions.  相似文献

This study examined the effect of and relationship between self- and prototypical identity influences on high-level mobile phone use from a theory of planned behavior (TPB) perspective. Participants were 252 university students who completed 2 questionnaires, 1 week apart. The first questionnaire assessed the standard TPB constructs (attitude, subjective norm, perceived behavioral control), as well as self- and prototypical identity influences. The second questionnaire assessed level of mobile phone use in the previous week. Support was found for the TPB in predicting high-level mobile use intentions and behavior. Self-identity and prototype similarity, but not prototype favorability, also significantly predicted intentions. The effects of prototype similarity on intentions were mediated via self-identity processes.  相似文献

Studies on implementation intentions so far have mainly pointed towards strengthened cue-behavior associations as the mechanism underlying the effectiveness of this self-regulatory tool. However, we propose that because it triggers people to look into the future and to mentally simulate their future behavior, planning by means of implementation intentions might go beyond the creation of goal-directed associations and thus lead to more enduring effects on behavior. We tested this hypothesis in an experiment using a longitudinal design, where participants formed an intention for a behavior that deviates from their routine, and furnished it either with associative learning of cue and behavior, forming implementation intentions, or nothing at all. Results showed that initially, learning cue-behavior associations led to the same rate of goal completion as forming implementation intentions. However, only the effect of implementation intentions was maintained at the second measurement one week later. These findings suggest that planning does more than merely create goal-directed associations, which might offer a new perspective on the workings and use of this important tool for behavior change.  相似文献

This research examined whether forming detailed implementation plans for achieving a goal improved older adults' adherence to a health behavior. Nondiabetic participants (N = 31) rehearsed, deliberated, or formed implementation intentions to perform home blood glucose monitoring, 4 times daily for 3 weeks. The implementation group performed tests nearly 50% more often than the 2 comparison groups. Results were not attributable to a priori differences in intentions to perform testing. Findings indicate that implementation intentions can facilitate older adults' performance of important medical self-care tasks in naturalistic settings over sustained periods of time and concur with previous research that implicates automatic cognitive processes that do not show age-related decline. These results support the utility of this technique for improving adherence to health behaviors in clinical populations.  相似文献

Purchase and consumption behaviors in daily life often are repetitive and performed in customary places, leading consumers to develop habits. When habits have formed, environmental cues can activate the practiced responses in the absence of conscious decision making. This research tested these ideas using a longitudinal design. We predicted that regardless of their explicit intentions, consumers would repeat habits to purchase fast food, watch TV news, and take the bus. The results yielded the anticipated pattern in which participants repeated habitual behaviors even if they reported intentions to do otherwise. Intentions only guided behavior in the absence of strong habits. This study ruled out a number of artifactual accounts for these findings including that they arise from the level of abstraction at which intentions are identified, the certainty with which participants held intentions, a restriction of range in the measures, and the strategy participants used to estimate frequency of past performance.  相似文献

Abstract

The present study was designed to examine the utility of the theory of reasoned action (Fishbein and Azjen, 1975) in relation to people's propensity to engage in a range of different safe sex strategies, including engaging in an exclusive sexual relationship, avoiding casual sex, and asking sexual partners about their previous sexual and IV drug use history. It was proposed that the intention to engage in a particular safe sex practice would be influenced by the person's attitude towards engaging in the practice, as well as his or her perception of the extent to which others thought they should do so (subjective norm), while behavioural intentions were proposed to predict actual behaviour. The study was also designed to examine whether, after control of the effects of the components of the theory of reasoned action, the person's generalised control beliefs would explain any additional variance in either behavioural intentions or actual behaviour. One hundred and two sexually active heterosexual students participated in the study. At the first wave of data collection, subjects completed measures of intentions, attitudes, and norms appropriate to each of the different behaviours. Measures of actual behaviour were obtained at follow-tip (three months after first period of data collection). The results of the study indicated that attitudes and norms predicted intentions for avoiding casual sex and asking sexual partners about their previous sexual and IV drug use history, while intentions predicted actual behaviour for all three safe sex strategies. Although there were no significant main effects of control beliefs on intentions or behaviour, subjects with internal control beliefs were more likely than their counterparts with external control beliefs to behave in accordance with their intentions to engage in an exclusive sexual relationship and ask sexual partners about their previous sexual and IV drug use history. Additional analyses revealed that the levels and determinants of intentions and actual behaviour were, in general, similar for males and females.  相似文献

There is abundant evidence that there is a performance cost associated with switching between tasks. This “switch cost” has been postulated to be driven by task performance on the preceding trial, but recent research challenges any necessary role of previous task performance in driving the cost. Across three experiments, we investigated whether it is difficult to switch from a task that was prepared but never performed. We replicated the finding of a switch cost following cue-only trials (involving no task performance) whilst controlling for a potential cue-switching confound. This cost was larger than that following completed trials when preparation interval was short (300?ms), and it reduced significantly with a longer preparation interval (1000?ms) on the current trial. We also found that preparing only to attend to a particular visual dimension (colour or shape) was sufficient to drive a significant subsequent switch cost, which appeared to be residual in nature; we speculate that this cost may reflect the persistence of unfulfilled task intentions and/or a strategic slowing when consecutive intentions conflict.  相似文献

Three cued signal detection experiments demonstrated a role for auditory memory traces in frequency selectivity. The extent to which the cue predicted the signal frequency affected the size of the advantage for signals at the cue frequency over those at distant frequencies when the cue-signal gap was 10 sec but not when it was 1 sec. Detection of occasional signals presented at uncued frequencies was enhanced when they matched the frequency of cues from recent trials. With "relative" cues, which were usually followed by signals at the musical fifth above the cue frequency, performance on occasional signals at the cue frequency was enhanced relative to other unexpected frequencies. These results suggest that, regardless of the listener's expectations and intentions, the detectability of a signal is enhanced if its frequency matches an existing memory trace. One form of voluntary attention to frequency may involve maintaining traces that would otherwise slowly decay.  相似文献

Little is known about the short- and long-term benefits mentors gain from their mentoring relationships. This study examined the extent to which short-term proximal benefits reported by mentors (improved job performance, recognition by others, rewarding experience, and loyal base of support) predicted the long-term distal outcomes of mentor career success, work attitudes and behavioral intentions to mentor in the future. Mentors’ reports of short-term mentoring benefits significantly predicted their work attitudes and their intentions to mentor again in the future, but were unrelated to their career success. Upon closer inspection, short-term instrumental mentor benefits (improved job performance, recognition by others) were more important in predicting mentor work attitudes, whereas short-term relational mentor benefits (rewarding experience, loyal base of support) were more important in predicting intentions to mentor in the future. Implications for mentoring theory, future research, and practice are discussed.  相似文献

Background. In many parts of the world, it is common for secondary school students to be involved in part-time employment. Research shows that working can have a negative impact on school engagement. However, the majority of studies have focused on the amount of time that students spend working rather than on the quality of work experience and its influence on school engagement. Aims. This study explored the relation of part-time work and school experiences to dropout intentions among secondary school and junior college students. The study was conceptualized from a self-determination theory perspective (Deci & Ryan, 2000). Sample. Participants were 3,248 students from rural and suburban schools in the greater region of Montreal, Canada. Method. Questionnaires were used to assess the number of hours worked, the extent to which work interfered with or facilitated school functioning, autonomy, competence, and relatedness experienced in the work and school domains. School performance and school dropout intentions were also assessed. Results. A curvilinear relation between work hours and dropout intentions was found, reflecting that part-time work began to be associated with higher dropout intentions only when students worked more than 7 hr per week. Analyses also showed that work–school interference was related to dropout intentions, and that this variable served to mediate the relation of employer autonomy support to dropout intentions. Conclusions. These results suggest that both the quantity and the quality of students’ part-time work experiences need to be considered when examining the relation of work to school engagement.  相似文献

Achieving and maintaining happiness can be difficult, especially when people are not engaging in the activities they know facilitate it. ‘Flow’ activities require clear rules, challenge, a high investment of energy, and have been shown to promote long-term happiness better than low investment, passive activities. Do people know this? In two studies, we found that, despite recognizing that flow activities are more likely to facilitate happiness, people nevertheless participated in passive leisure significantly more often in a typical week. Participants rated passive activities as being significantly more enjoyable, requiring less effort, and being less daunting to get started than flow activities. Participants’ engagement in flow activities was significantly predicted by how enjoyable the activities were perceived to be, whereas how daunting those activities were rated predicted non-engagement. Passive activity engagement was only significantly predicted by enjoyment. Suggestions for enabling people to rise above the barriers to flow activities are offered.  相似文献

The social networking site (SNS) Facebook is becoming increasingly recognized as a medium through which individuals can investigate and monitor others' activities. However, little is known about whether Facebook monitoring behavior occurs within romantic relationships and, accordingly, the psychological predictors of this behavior. The present study employed an extended theory of planned behavior (TPB) framework including self-esteem, partner trust, and demographic characteristics, to predict frequent Facebook partner-monitoring. Facebook users (N=244) in romantic relationships completed measures assessing the standard TPB constructs (attitude, subjective norm, and perceived behavioral control), additional predictor variables (self-esteem and partner trust), and demographic characteristics (age, gender, relationship length, daily Facebook logins, and time spent per login). One week later, participants reported their level of Facebook partner-monitoring during the previous week. Regression analyses supported the standard TPB constructs of attitude and subjective norm in predicting intentions to engage in frequent Facebook partner-monitoring, with intention, in turn, predicting behavior. Partner trust, but not self-esteem, significantly predicted frequent Facebook partner-monitoring intentions. Of the demographic characteristics, daily Facebook logins significantly predicted both intention and behavior and, unexpectedly, relationship length directly affected behavior. Overall, the current study revealed that frequent Facebook partner-monitoring is influenced by attitudinal, normative, and relational factors and, potentially, increased visits to Facebook. These findings provide a new understanding of an individual's use of the world's leading SNS to monitor their partner's activities and provide a foundation for future studies to investigate the potential negative implications this activity may have for those in romantic relationships.  相似文献

This article evaluates two theoretical accounts of how sarcasm is understood; the traditional model, which asserts that listeners derive a counterfactual inference from the sarcastic comment, and relevance theory, which asserts that listeners recognize sarcasm as a scornful echo of a previous assertion. Evidence from normal speakers provides only partial support for both theories. Evidence from brain-injured populations suggests that aspects of the pragmatic process can be arrested in ways not predicted by either theory. It is concluded that sarcasm is more effortful to process than nonsarcastic comments and that inferences about the facts of the situation and the mental state of the speaker (e.g., attitudes, knowledge, and intentions) are important to comprehending sarcasm. It is questioned whether inferences about mental state are relatively more difficult for brain-injured subjects and, if so, whether this is a continuum of difficulty or reflects reliance upon different cognitive processes.  相似文献

This longitudinal study examined the relative merits of two alternative perspectives on the interplay between work–family conflict, social support, and turnover intentions. According to the cross-domain perspective, family-to-work conflict (FWC) should be more important in predicting increases in turnover intentions than work-to-family conflict (WFC). According to the matching-perspective, however, WFC should be more important in predicting increases in turnover intentions than FWC. We expanded the debate about matching- versus cross-domain relationships by testing whether resources (i.e., social support) should stem from the same domain (i.e., work or family) as the conflict (i.e., matching-principle) or from the other domain (i.e., cross-domain perspective). Additionally, authors hypothesized that changes in WFC and FWC predicted changes in turnover intentions and tested reciprocal relationships between WFC/FWC and turnover intentions. This longitudinal study (5-month time lag) with 665 employees revealed that (increases in) WFC predicted increases in turnover intentions, whereas (increases in) FWC did not. The relationship between WFC and increases in turnover intentions was buffered by work–family specific leader support but not by work–family specific support from family and friends. Further, results revealed reverse relationships such that turnover intentions predicted increases in WFC and FWC. Taken together, the results of this study supported the matching-principle rather than the cross-domain perspective. The reverse relationships found between work–family conflict and turnover intentions challenge the common view that work–family conflict antecedes turnover intentions in a unidirectional way.  相似文献
