Organizations often communicate seemingly paradoxical strategic imperatives to their employees that reflect a focus on promotion (take risks) and prevention (be prudent), as outlined by regulatory focus theory. When consistently emphasized and reinforced in an organization, these strategic inclinations can emerge as divergent climates for promotion and prevention that cloud the organization's perceived identity and reduce collective organizational commitment among employees. With a coherent organizational identity acting as both a sensemaking tool and a means of potential self-enhancement for employees, we use social identity theory to hypothesize that similarly emphasized promotion and prevention climates are negatively related to employees’ collective organizational commitment and indirectly, negatively related to organizational productivity. We test our hypotheses in a sample of 107 manufacturing organizations, using polynomial regression with response surface analysis to examine how similarly emphasized promotion and prevention climates relate to collective commitment and organizational productivity. Our analyses reveal that as organization-level promotion and prevention climate scores became more similar, collective organizational commitment decreases. Furthermore, we find that similarly emphasized promotion and prevention climates are negatively related to organizational productivity via collective commitment. We reconcile these findings with the organizational paradox and ambidexterity literatures and implicate promising avenues for future research. 相似文献

For pairs of meaningful items (e.g., words), recall accuracy is nearly identical for forward and backward probes. That is, after studying an A-B pair, subjects can recall A given B as well as they can recall B given A (Kahana, 2002). To assess whether this symmetry property is unique to pairs, we investigated the effects of study direction on probed recall of word triples and serial lists. Two experiments revealed a forward-recall advantage in both triples and serial lists. In addition, compound cues produced better recall than did single-item adjacent cues, which, in turn, produced better recall than did remote cues. These findings suggest a discontinuity between the associative processes supporting memory for pairs and those supporting memory for sequences of three or more items. 相似文献

The impact of specialist psychosocial treatment on health service use costs by patients with personality disorder is not yet sufficiently documented. In this prospective study we compare patterns of health service costs by three groups of people with personality disorder treated in a hospital-based program (IPP), a step down program (SDP), and a general psychiatric program (GPP). Total service use costs at follow up, compared with intake costs, showed that significantly higher savings were achieved by SDP and IIP compared with GPP. Cost reductions in SDP were significantly greater than in IPP. Significant cost reductions were found between treatment programs in social worker and community psychiatric nursing and psychotherapy. The cost-effectiveness of the two specialist treatment programs was indicated by the significant association between total cost reduction and clinical outcome in GPP and IPP, but not in GPP. The effect of Major Depression and Borderline Personality Disorder on health service use alone and in combination was also investigated. The finding that Major Depression was found to be more significantly associated with higher health service use costs than Borderline Personality Disorder is discussed. 相似文献

Recent meta-analysis has demonstrated that attitudes and associates are among the best predictors of antisocial behavior. Despite this finding, there are few psychometrically developed and validated measures of criminal and antisocial attitudes and associates. This study reviews the theoretical and empirical development of the Measures of Criminal Attitudes and Associates (MCAA), which is composed of two parts. Part A is a quantified self-report measure of criminal friends. Part B contains four attitude scales: Violence, Entitlement, Antisocial Intent, and Associates. The MCAA showed reasonable reliability (internal consistency and temporal stability) and appropriate convergent and discriminant validity. Criterion validity was evidenced in the scale's relationship with criminal history variables, and a factor analysis confirmed the four distinct scale domains. 相似文献

We addressed several questions regarding the relation of anxiety sensitivity to anxious symptoms among 47 youth psychiatric inpatients (18 boys, 29 girls), ages 9–17 (M = 14.23, SD = 1.89). Participants completed measures of anxiety sensitivity, anxious and depressive symptoms, trait anxiety, and positive and negative affect; chart diagnoses were available. Consistent with hypotheses, we found that (a) anxiety sensitivity was associated with anxious symptoms, even controlling for trait anxiety and depressive symptoms; and (b) anxiety sensitivity displayed symptom specificity to anxious versus depressive symptoms (i.e., was associated with anxiety controlling for depression but not with depression controlling for anxiety). Furthermore, regarding factors of anxiety sensitivity, we obtained mixed support for our prediction that phrenophobia would be associated with both depression and anxiety, whereas fear of physical arousal would be associated with anxiety but not depression. Implications for the construct validity of anxiety sensitivity were discussed. 相似文献

To test for a relation between individual differences in personality and neural-processing efficiency, we used functional
magnetic resonance imaging (fMRI) to assess brain activity within regions associated with cognitive control during a demanding
working memory task. Fifty-three participants completed both the self-report behavioral inhibition sensitivity (BIS) and behavioral
approach sensitivity (BAS) personality scales and a standard measure of fluid intelligence (Raven’s Advanced Progressive Matrices).
They were then scanned as they performed a three-back working memory task. A mixed blocked/ event-related fMRI design enabled
us to identify both sustained and transient neural activity. Higher BAS was negatively related to event-related activity in
the dorsal anterior cingulate, the lateral prefrontal cortex, and parietal areas in regions of interest identified in previous
work. These relationships were not explained by differences in either behavioral performance or fluid intelligence, consistent
with greater neural efficiency. The results reveal the high specificity of the relationships among personality, cognition,
and brain activity. The data confirm that affective dimensions of personality are independent of intelligence, yet also suggest
that they might be interrelated in subtle ways, because they modulate activity in overlapping brain regions that appear to
be critical for task performance. 相似文献

The psychometric function relates an observer’s performance to an independent variable, usually some physical quantity of a stimulus in a psychophysical task. This paper, together with its companion paper (Wichmann & Hill, 2001), describes an integrated approach to (1) fitting psychometric functions, (2) assessing the goodness of fit, and (3) providing confidence intervals for the function’s parameters and other estimates derived from them, for the purposes of hypothesis testing. The present paper deals with the first two topics, describing a constrained maximum-likelihood method of parameter estimation and developing several goodness-of-fit tests. Using Monte Carlo simulations, we deal with two specific difficulties that arise when fitting functions to psychophysical data. First, we note that human observers are prone to stimulus-independent errors (orlapses). We show that failure to account for this can lead to serious biases in estimates of the psychometric function’s parameters and illustrate how the problem may be overcome. Second, we note that psychophysical data sets are usually rather small by the standards required by most of the commonly applied statistical tests. We demonstrate the potential errors of applying traditionalX 2 methods to psychophysical data and advocate use of Monte Carlo resampling techniques that do not rely on asymptotic theory. We have made available the software to implement our methods. 相似文献

In visual search tasks, observers look for targets in displays containing distractors. Likelihood that targets will be missed varies with target prevalence, the frequency with which targets are presented across trials. Miss error rates are much higher at low target prevalence (1%-2%) than at high prevalence (50%). Unfortunately, low prevalence is characteristic of important search tasks such as airport security and medical screening where miss errors are dangerous. A series of experiments show this prevalence effect is very robust. In signal detection terms, the prevalence effect can be explained as a criterion shift and not a change in sensitivity. Several efforts to induce observers to adopt a better criterion fail. However, a regime of brief retraining periods with high prevalence and full feedback allows observers to hold a good criterion during periods of low prevalence with no feedback. 相似文献

The cognitive literature now shows how critically math performance depends on working memory, for any form of arithmetic and
math that involves processes beyond simple memory retrieval. The psychometric literature is also very clear on the global
consequences of mathematics anxiety. People who are highly math anxious avoid math: They avoid elective coursework in math,
both in high school and college, they avoid college majors that emphasize math, and they avoid career paths that involve math.
We go beyond these psychometric relationships to examine the cognitive consequences of math anxiety. We show how performance
on a standardized math achievement test varies as a function of math anxiety, and that math anxiety compromises the functioning
of working memory. High math anxiety works much like a dual task setting: Preoccupation with one’s math fears and anxieties
functions like a resource-demanding secondary task. We comment on developmental and educational factors related to math and
working memory, and on factors that may contribute to the development of math anxiety. 相似文献

This study investigated an integrative, psychological model of suicidality involving the relationship between perfectionism and future thinking to predict short-term outcome in well-being following a suicidal episode. Two hundred and sixty-seven adults hospitalized following a self-harm episode completed a range of clinical and psychological measures in hospital and were followed up approximately two months after discharge. Hierarchical regression analyses confirmed that, among the suicidal self-harmers who had a history of repetitive self-harm (n=65), outcome among low social perfectionists changed as a function of positive future thinking such that outcome was better for those high on positive thoughts compared with those low on positive future thoughts. There was no such positive change in outcome among the high social perfectionists. There were also no significant interactive effects evident among the non-repetitive self-harmers (n=61). These findings extend recent research to suggest that socially prescribed perfectionism and positive future thinking (but not negative future thinking) are implicated in outcome following repetitive suicidality. Implications for theory and clinical practice are discussed. 相似文献
