Two studies are reported examining academic procrastination and motivation in 1,145 university students from Canada and Singapore. In Study 1, relationships between procrastination and motivation variables were found to be similar across contexts, with self‐efficacy for self‐regulated learning most strongly associated with procrastination in both contexts. In Study 2, patterns of procrastinating behavior and the negative impact of procrastination were examined and compared in Canadian and Singaporean undergraduates. Participants in both contexts reported writing to be the academic task most prone to procrastination. More Singaporeans than Canadians were classified as negative procrastinators (i.e. rated procrastination as a negative influence on academic functioning). In both contexts, negative procrastinators spent more time procrastinating than neutral procrastinators and displayed lower self‐efficacy for self‐regulated learning. On décrit deux recherches portant sur la motivation et la procrastination universitaire (tendance à remettre au lendemain) de 1145 étudiants du Canada et de Singapour. Dans la première étude, les relations entre la motivation et la procrastination sont apparues être analogues dans les deux pays, la variable la plus fortement associéà la procrastination étant l'auto‐efficience pour l'apprentissage autorégulé. Dans la deuxième étude, les schémas comportementaux de procrastination et son impact négatif ont été analysés et comparés chez les étudiants de 1° cycle canadiens et singapouriens. Les sujets des deux pays ont mentionné la rédaction comme étant la tâche universitaire la plus soumise à la procrastination. Davantage de Singapouriens que de Canadiens été classés en procrastinateurs négatifs (c'est‐à‐dire que la procrastination est considérée comme étant un handicap pour les études). Dans les deux cas, les procrastinateurs négatifs gaspillaient plus de temps que les procrastinateurs neutres et manifestaient une moindre auto‐efficience pour l'apprentissage autorégulé. 相似文献

Abstract.— When two single-cue probability learning tasks with different amounts of unpredictable variance were learned in succession. a low variance task interfered with the retention of a high variance task, but the opposite was not true. The effects were positive in that they enabled the subjects to reach a higher response consistency and, thus, a higher level of achievement. It was suggested that the subjects made use of the low variance task to reject incorrect hypotheses about the cue-criterion relation and that interference from an interpolated task occurs only when this task provides information which has functional value for the subject. 相似文献

Younger and older adults listened to discourse in quiet and in conversational noise, before answering questions concerning the material. Some questions required listeners to recall specific details; others were of a more integrative nature. When the listening situation was adjusted for individual differences in hearing, younger and older adults were equally adept at remembering the gist of the passages in both quiet and in two levels of noise. The two age groups also did not differ with respect to memory for specific details when listening in quiet or in a moderate level of noise, even when required to perform a concurrent task. Only at the loudest noise level did younger adults tend to recall more detail than older adults. However, when no adjustments were made to compensate for the poorer hearing of older adults (all participants tested under identical listening conditions), older adults could not recall as much detail as younger adults, either in quiet or in noise. The results indicate that the speech-comprehension difficulties of older adults primarily reflect declines in hearing rather than in cognitive ability. 相似文献

When employees consciously withhold potentially important suggestions or concerns from those who may be able to act on that information, it can have serious implications for organizational performance. Yet there is research suggesting that, when faced with the choice of whether or not to raise an issue, employees often choose to remain silent. Our objective in this paper is to expand current theoretical understanding of why employees often remain silent and of situational factors that can lessen this tendency. Drawing on the approach‐inhibition theory of power, we argue that an employee's personal sense that he or she is lacking in power in relation to others at work is a key factor contributing to the decision to remain silent but that this effect is moderated by perceived target openness. We took a multimethod approach, testing these relationships across 3 studies: a laboratory experiment, a survey study of healthcare workers, and a survey study of employees working across a wide range of industries. Our findings suggest that, although silence is indeed rooted in the psychological experience of powerlessness, perceived target openness mitigates this relationship, encouraging employee to speak up when they would not otherwise do so. 相似文献

In 3 studies, participants viewed sequences of multiattribute objects (e.g., colored shapes) appearing with varying frequencies and judged the likelihood of the attributes of those objects. Judged probabilities reflected a compromise between (a) the frequency with which each attribute appeared and (b) the ignorance prior probability cued by the number of distinct values that the focal attribute could take on. Thus, judged probabilities were partition dependent, varying with the number of events into which the state space was subjectively divided. This bias was diminished among participants more confident in what they learned, was strong and insensitive to level of confidence when ignorance priors were especially salient, and required ignorance priors to be salient only when probabilities were elicited (not during encoding). 相似文献

The effectiveness of a fixed‐ratio (FR) escalation procedure, developed by Pinkston and Branch (2004) and based on interresponse times (IRTs), was assessed during lever‐press acquisition. Forty‐nine experimentally naïve adult male Long Evans rats were deprived of food for 24 hr prior to an extended acquisition session. Before the start of the session, three food pellets were placed in the magazine. Otherwise, no magazine training, shaping, nor autoshaping procedure was employed. The first 20 presses each resulted in the delivery of a 45‐mg food pellet. Then, the FR increased (2, 4, 8, 11, 16, 20, 25, 30) when each IRT in the ratio was less than 2 s during three consecutive ratios. Sessions lasted 13 hr or until 500 pellets were earned. On average, rats reached a terminal ratio of 11 (mean) or 16 (median) during the first session. Seven rats reached the maximum value of FR 30 and only one rat did not acquire the response. In most rats, a break‐and‐run pattern of responding characteristic of FR schedules began to develop in this acquisition session. Subsequently, the ratio‐escalation procedure continued during daily 2‐hr sessions. In these sessions, the starting ratio requirement was set at the terminal ratio reached in the previous session. Using this procedure, over half (26) of the rats reached the FR 30 requirement by the fourth session. These data demonstrate that a ratio‐escalation procedure based on IRTs provides a time‐efficient way of establishing ratio responding. 相似文献

This research explores when and how tailoring messages to attitudinal bases backfires. Study 1 demonstrated that for attitudes (toward education subsidies) that were based more on beliefs than emotions, recipients whose initial attitudes were incongruent with the message position (i.e., message opponents) showed mismatching effects, such that the affective message was more persuasive than the cognitive message. Study 2 replicated these mismatching effects among message opponents for attitudes (toward a rival university) that were primarily affective. Study 3 controlled for effects of initial attitude certainty and replicated the mismatching effects of Study 2 for affective attitudes toward an increase in tuition. Finally, Study 4 suggested a potential mechanism for mismatching effects, revealing that for attitudes (toward an online course management system) that were based more on beliefs than emotions, message opponents counter‐argued with the cognitive appeal more intensely than the affective appeal. Contrary to the notion in the extant literature that mismatching effects are relatively rare compared with matching effects, the current research suggests that mismatching effects occur for both primarily affective and cognitive attitudes when the recipient is highly opposed to the message position. The present findings also demonstrate the utility of examining attitudinal bases at the object level in the context of message tailoring. Implications for message tailoring and for affective versus cognitive attitudes are discussed. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献

In humans, eight monosaccharides are required for the synthesis of glycoproteins. Dietary supplements that supply these crucial
sugars are known as glyconutrients. A glyconutrient compound was added to Peripheral Blood Mononuclear Cells (PBMC) isolated
from normal controls and patients with the Chronic Fatigue Syndrome (CFS), a disease associated with immune dysregulation.
The in vitro immunomodulatory effects were investigated. Cell surface expression of the glycoproteins CD5, CD8, and CD11a
were significantly lower in patients with CFS compared to normal controls. Addition of glyconutrient homogenate to PBMC from
patients with CFS stimulated with phytohemagglutinin significantly increased the expression of each glycoprotein. Furthermore,
natural killer (NK) cell function was reduced in CFS patients. The glyconutrient preparation significantly enhanced NK cell
activity versus human herpes virus 6 (HHV-6)-infected H9 cells in an 8 h51Cr release assay compared to placebo for PBMC from patients with CFS (p<.01). Finally, apoptosis was significantly higher
in patients with CSF. The percentage of apoptotic cells was significantly decreased in PBMC from patients with CFS that had
been incubated for 48 h with glyconutrients. Thus, glyconutrients improved abnormal immune parameters in vitro in patients
with CFS.

The authors investigated the predictive utility of people's subjective assessments of whether their evaluations are affect- or cognition driven (i.e., meta-cognitive bases) as separate from whether people's attitudes are actually affect- or cognition based (i.e., structural bases). Study 1 demonstrated that meta-bases uniquely predict interest in affective versus cognitive information above and beyond structural bases and other related variables (i.e., need for cognition and need for affect). In Study 2, meta-bases were shown to account for unique variance in attitude change as a function of appeal type. Finally, Study 3 showed that as people became more deliberative in their judgments, meta-bases increased in predictive utility, and structural bases decreased in predictive utility. These findings support the existence of meta-bases of attitudes and demonstrate that meta-bases are distinguishable from structural bases in their predictive utility. 相似文献
