This study focuses on intra-individual variability in personality at work, and how it relates to job performance. 288 professionals completed contextualised adjective-based personality assessments in work and non-work contexts, and a non-contextualised personality measure. Ratings of their personality were also obtained from colleagues, family members and friends. Supervisors provided performance ratings for 130 participants. Results indicate that personality is context- and source-dependent, and varies systematically within contexts intra-individually regardless of source. Whilst this variability was predictive of some performance criteria when based on other-ratings, overall predictive effects were small in number and size. This study adds to the relatively small body of research on personality variability and performance and contributes to the conceptualisation of personality as a dynamic construct. 相似文献

Investigators have begun to take a multimodal approach to the assessment and treatment of psychosocial risk factors for cardiovascular disease (CVD). For instance, cognitive responses have become the focus of contemporary research along with continued examination of overt Type A behaviors. Price (1982) has outlined a set of beliefs purportedly associated with Type A behavior and subsequent CVD risk. The current study examines the validity of this belief set as represented by a newly developed measure, the Type A Cognitive Questionnaire (TACQ). Subjects were 221 employed adults participating in a worksite CVD risk reduction program. They completed the TACQ as part of a pretreatment CVD risk screening protocol. As hypothesized, TACQ scores were significantly associated with Type A behavior, hostility, physiological mediators of CVD, and psychosocial distress. Discussion addresses continued refinement of the Type A belief construct. 相似文献

Results are presented for the 1st analysis of the relationship between IQ and completed fertility using a large, representative sample of the US population. Correlations are predominantly negative for cohorts born between 1894 and 1964 but are significantly more positive for cohorts whose fertility was concentrated in the baby boom years. Previous studies reporting slightly positive correlations appear to have been biased in their restriction of samples to atypical cohorts. The National Opinion Research Center (NORC), a nonprofit research organization affiliated with the University of Chicago, conducted the General Social Survey (GSS) in the US each year from 1972 to 1982, except for 1979. A combination of block quota and full probability sampling was employed. Hour-long interviews were completed with 12,120 respondents who were English-speaking, noninstitutionalized adults (18 years or older) living within the continental US. Such questions as age, place of birth, income and occupation, were asked in each interview. Other questions about attitudes on various social, political, and moral issues were rotated in different years. The unique opportunity this data set affords is an overview of the relationship between intelligence and fertility for a nationally representative sample of Americans whose major reproductive years fell between 1912 and 1982. Data were consolidated from the 4 surveys in which the vocabulary test was given (1974, 1976, 1978, and 1982). Respondents were divided into 15 birth cohorts of 5-year intervals ranging from before 1894 to 1964. Correlations between vocabulary scores and number of siblings are markedly negative across all 15 cohorts. Vocabulary sibling correlations are more negative in every cohort than vocabulary offspring correlations. Previous reports of a neutral or slightly eugenic relationship appear to be due to the nature of the samples used, in part because the cohorts chosen were atypical, and in part because they did not include nonwhites. Childless respondents averaged slightly higher scores than did those with 1 or more children, indicating that the automatic exclusion of the childless from sibling-IQ studies has not spuriously inflated negative correlations. 相似文献

This note presents the hypothesis than the excessively forceful closure of the mouth of larynx associated with certain types of stuttering may involve a neurological confusion between speech and the human body's Valsalva mechanism, which is designed to increase pulmonary pressure by forceful closure of the upper airway to assist in many types of physical effort. It is suggested that such behavior may result from excessive neuromotor tuning of the Valsalva mechanism prior to speech, especially in situations where the stutterer anticipates the need to “try hard” to speak properly. Such tuning may both interfere with phonation and render the Valsalva mechanism overexcitable to triggering stimuli, such as the increase in subglottal pressure that accompanies the start of articulation. 相似文献

The clustering of disfluency within early utterances in the speech of four nonstuttering children was examined. During the developmental period their mean length of utterance was between 2.25 and 3.0 morphemes. The frequency and characteristics of the clustered disfluencies are described and compared with single disfluent moments. Clusters of two disfluencies were analyzed for interactive effects of positional preference and type. Results were similar to those found in older preschool nonstuttering speakers, demonstrating the normal developmental nature of clustering in early sentences. Implications for using this temporal measure to differentially diagnose normal from abnormal disfluency are discussed. 相似文献

The present article presents an overview of the instruments that have been used to assess the Type A behavior pattern in children and adolescents. The development, usage, and psychometric properties of each assessment technique are discussed, with methodological concerns being addressed whenever appropriate. The Matthews Youth Test for Health is the assessment of choice for children, because of its brevity, ease of administration, and adequate psychometric properties. The Hunter-Wolf A-B Rating Scale is desirable only for older, highly literate children. The Adolescent Structured Interview appears to be the most promising device for the adolescent age range. The other adolescent assessment devices are relatively unpopular, difficult to administer, and not always conceptually parallel to existing research on Type A behavior. Recommendations for future research are presented. 相似文献

This study investigated the relationship among anger, the Type A construct, and cardiovascular reactivity. The Novacco Anger Scale and the Jenkins Activity Survey (JAS) were used to measure anger proneness and Type A characteristics, respectively. Twenty-four college males were selected from the upper and lower quintiles of the JAS distribution. During the study, the subjects were exposed to varying levels of experimentally induced challenge, while measurements were taken of heart-rate and blood-pressure changes. The results showed a modest but significant correlation between scores on the Novacco Anger Scale and the JAS. More importantly, scores on the Novacco Anger Scale correlated significantly with heart rate and systolic blood pressure under all challenge conditions, while those on the JAS were unrelated to cardiovascular excitability. These results raise questions about the usefulness of the JAS as a predictor of CHD risk. They are also consistent with the beliefs of other investigators that anger and hostility are the most important Type A behaviors in predisposing patients to coronary heart disease. Additional implications of the study are discussed. 相似文献
