Prior findings suggest managers often choose ranges to communicate uncertainty in future earnings. We analyzed earnings forecasts over 11 years and find higher earnings uncertainty firms are more likely to choose range estimates. We study investors’ attitudes to forecast precision and argue investors’ evaluations of forecasts can be explained by a sequential non-compensatory two-stage process – First, investors determine whether a point or a range estimate is more appropriate for a particular domain based on the congruence principle. Then, they seek the most precise reasonable range to maximize informativeness. Results from three experiments indicate the preference for (im)precision is non-monotonic – it peaks for low levels of imprecision and diminishes when the range gets wider, and is consistent with participants’ desire for congruent and informative estimates, and supports the claim that investors favor forecasts that are as precise as warranted by the information available, but not more precise.  相似文献

The purpose of this study was to investigate whether brain activity related to the presence of stuttering can be identified with rapid functional MRI (fMRI) sequences that involved overt and covert speech processing tasks. The long-term goal is to develop sensitive fMRI approaches with developmentally appropriate tasks to identify deviant speech motor and auditory brain activity in children who stutter closer to the age at which recovery from stuttering is documented. Rapid sequences may be preferred for individuals or populations who do not tolerate long scanning sessions. In this report, we document the application of a picture naming and phoneme monitoring task in 3 min fMRI sequences with adults who stutter (AWS). If relevant brain differences are found in AWS with these approaches that conform to previous reports, then these approaches can be extended to younger populations. Pairwise contrasts of brain BOLD activity between AWS and normally fluent adults indicated the AWS showed higher BOLD activity in the right inferior frontal gyrus (IFG), right temporal lobe and sensorimotor cortices during picture naming and higher activity in the right IFG during phoneme monitoring. The right lateralized pattern of BOLD activity together with higher activity in sensorimotor cortices is consistent with previous reports, which indicates rapid fMRI sequences can be considered for investigating stuttering in younger participants.Educational objectives: The reader will learn about and be able to describe the: (1) use of functional MRI to study persistent developmental stuttering; (2) differences in brain activation between persons who stutter and normally fluent speakers; and (3) potential benefit of time efficient fMRI sequences combined with a range of speech processing tasks for investigating stuttering in younger populations.  相似文献

Engaging in a chronological retrospection of my professional and personal transdisciplinary practice of walking-based research over the past decade, and embedding some elements of arts-based writing into the article itself, I articulate the influence of walking art, transect walks by urban researchers, and especially of Sarah Pink’s sensory ethnography on his own use of walking-based method-elements for sustainability research. I discuss how these approaches bear relevance to urban sustainability research and suggest a queer-ecological direction for walking-based transdisciplinary research.  相似文献

Evidence suggests that cancer risk assessment may be associated with increased psychological distress. This exploratory study assessed the necessity and acceptability of incorporating psychological counseling into routine clinic procedures at a cancer risk program. Following a visit to a university-based cancer risk clinic, patients (N = 102) completed an anonymous self-report instrument. Participants reported experiencing current stress and anxiety (41%), depression (29%), and suicidal ideation (2%). Patients with a history of cancer were more likely to be experiencing current emotional difficulties. Sixty-nine percent of the participants found the visit with the psychological counselor to be helpful, while 41% of the participants reported interest in follow-up psychological services. Interest in receiving future psychological services was positively correlated with levels of anxiety, depression, and cancer worry. This pilot study demonstrates the acceptability and potential role for psychological counselors in increasing adjustment in high-risk patients undergoing genetic counseling for inherited cancers.  相似文献

This theoretical integration of social psychology's main cognitive and affective constructs was shaped by 3 influences: (a) recent widespread interest in automatic and implicit cognition, (b) development of the Implicit Association Test (IAT; A. G. Greenwald, D. E. McGhee, & J. L. K. Schwartz. 1998), and (c) social psychology's consistency theories of the 1950s, especially F. Heider's (1958) balance theory. The balanced identity design is introduced as a method to test correlational predictions of the theory. Data obtained with this method revealed that predicted consistency patterns were strongly apparent in the data for implicit (IAT) measures but not in those for parallel explicit (self-report) measures. Two additional not-yet-tested predictions of the theory are described.  相似文献

In everyday life, close relationship partners enact behaviors through which they may influence each other. To understand how these exchanges affect partners, previous research has emphasized the enactors' reports, the receivers' perceptions, or the congruence of the two. We developed a strategy based on classic signal detection theory that combined elements from these three approaches in a naturalistic daily experience study. Members of 58 heterosexual dating couples reported daily on their own behaviors and their perceptions of their partners' behaviors. Results showed that an enactor's beliefs about his or her behavior and the perceiver's interpretation combined to affect daily mood and relationship satisfaction. However, different patterns of results emerged for positive and negative behaviors, such that the enactor's perspective accounted for independent effects of negative behaviors. Results show the value of simultaneously considering the perspective of both parties in social interaction.  相似文献

Two studies examined how dispositional approach-related and avoidance-related motivations moderate the degree to which people base satisfaction judgments on past experiences of positive affect (PA) and negative affect (NA). Using both laboratory-based (Study 1) and experience sampling (Study 2) methodologies, the authors found that high approach participants, as compared with low approach participants, made satisfaction ratings that were more strongly tied to PA. In contrast, avoidance-related motivations did not moderate the degree to which satisfaction ratings were based on either PA or NA. Results indicate that approach motivations may influence well-being not only through emotion over time but also through the degree to which people weight particular emotional experiences in broader judgments of satisfaction.  相似文献

This study investigated changes in risk-taking propensity on a behavioral decision-making task as a function of varying social conditions with peers. In contrast to the effects of direct peer influence (pro-risk and anti-risk messages by peers), we included a socially ambiguous context (neutral messages by peers) and a no-peer control (participants alone) as comparison conditions. Using a counterbalanced mixed factorial design, college students (N = 187) completed the Balloon Analogue Risk Task-Youth (BART-Y) twice during two consecutive sessions, including once alone and once with a confederate; the control group completed two sessions of the task alone. The findings showed that, in general, direct pro-risk messages led to the most robust and consistent changes in risk-taking. The findings are discussed in terms of the multidimensional and multidirectional nature of peer influence during the college years.  相似文献

This research explores the reported experiences of working parents of disabled children with respect to formal and informal sources of child‐care, the need for which extends beyond the childhood years. Forty families with at least one disabled child, representing a variety of family structures and work situations, participated in semi‐structured interviews. The resultant data revealed an analytical axis of disabling and enabling features of child‐care. These are illustrated here with reference to the parents' accounts. Disabling barriers were physical, attitudinal or material. However, some features of either formal or informal care served to dismantle these barriers. Where formal child‐care was available, appropriate, flexible and accommodating to the needs of both the parents and the disabled child, the parents reported being able to combine working and caring roles successfully. However, where formal supports were inadequate or non‐existent, parents who could rely on the support of family and friends to supply emotional and instrumental assistance reported balance between work and caring roles. Whilst all parents need satisfactory child‐care in the early years, these parents' needs extend beyond the childhood years: the parents' accounts highlighted their complex and long‐term child‐care needs. Options for further research were proposed which would emphasize negotiation within families over time, or would focus on intersections of other parts of the work‐family‐community system.
