ABSTRACT Both entrepreneurs and senior-level college business students were surveyed to determine similarities and differences in their values, under the premise that students who share similar values with those held by entrepreneurs may have promise of entrepreneurial potential. All respondents were administered the Rokeach Value Survey which, through a process of rank-ordering, is used to determine two hierarchies of value importance for individuals. The first hierarchy reflects an individual's terminal value system, or those values associated with end-states of existence. The second hierarchy reflects an individual's instrumental value system, or those values associated with modes of conduct. The resulting data provided a tabulation of medians, rank order composites and levels of significance for the terminal and instrumental values, respectively, of both samples. Rank order composites were used as general indices in comparing the position of a particular value in the total hierarchy of values and for comparing the position of a particular value across the two groups. Emphasis was placed on those values which were ranked very low or very high by the entrepreneurs. Comparisons of student value rankings relative to those values the entrepreneurs held highest and lowest were then conducted. The findings indicated that there were value differences between the total sample of entrepreneurs and students, as well as between female entrepreneurs and female student values, but there were few differences between male entrepreneur and male student values. In addition to the above comparisons, median analysis between entrepreneur and student terminal and instrumental values were conducted. An examination of the general population of entrepreneurs and students revealed that twelve of the eighteen terminal values of the entrepreneurs and students were significantly different at the (.05) level Only four of the eighteen instrumental values were significantly different (.05) level between the entrepreneurs and students. The median analysis between male entrepreneurs and male student values showed no significant differences. However, the median analysis between female entrepreneur and female student values showed that seven of the eighteen instrumental and eleven of the eighteen terminal values were significantly different at the (.05) level. Although not examined, it is likely that individual students in the sample do share the value profiles of the entrepreneurs. If so, and if generally accepted value profiles are established for entrepreneurs, such students might be counseled to consider the entrepreneurial life.  相似文献

An overview is presented of a pilot psychoendocrine study of PTSD inpatients in comparison with several subgroups of schizophrenic and affective disorder patients. Using a hormonal profile including Cortisol, norepinephrine, epinephrine, testosterone, and thyroxine, it was found that the mean values for the PTSD group were at or near the extreme end of the range for every hormone measured, i.e., relatively low for Cortisol and high for the remaining hormones. The possible clinical meaning of these findings is considered in the light of prior psychoendocrine research on chronic stress. The hormonal alterations in PTSD appear to be persistent and suggest the possibility of being linked largely to traits or character structure, perhaps particularly to cognitive variables related to defense and coping mechanisms, as reviewed in detail for each hormonal system. There appears to be a potential for a fruitful union between the traumatic stress and psychoendocrine fields and some future strategies for developing and strengthening such a union are suggested.  相似文献

Previous studies suggest that adults and children divide spoken syllables into subsyllabic onset-rime units more readily than into any other kind of subsyllabic unit. We asked whether this same onset-rime segmentation might also be beneficial in teaching children to read. That is, can children learn more words segmented at the onset-rime boundary (e.g., CL-AP, D-ISH) than words segmented after the vowel (CLA-P, DI-SH)? In three experiments, first-grade students studied single words presented by a computer connected to a high-quality speech synthesizer. Experiment 1 used words of four letters but only three phonemes apiece (e.g., WHIP, DISH). In some of these words the onset-rime segmentation corresponded to the initial bigram (e.g., WH-IP); in some it did not (e.g., D-ISH). Experiments 2 and 3 used words of four letters and four phonemes (e.g., CLAP, CORN). In all three experiments, onset-rime segmentation proved more helpful than postvowel segmentation in short-term learning of the words.  相似文献

The concept of a universal human nature, based on a species-typical collection of complex psychological adaptations, is defended as valid, despite the existence of substantial genetic variation that makes each human genetically and biochemically unique. These apparently contradictory facts can be reconciled by considering that (a) complex adaptations necessarily require many genes to regulate their development, and (b) sexual recombination makes it improbable that all the necessary genes for a complex adaptation would be together at once in the same individual, if genes coding for complex adaptations varied substantially between individuals. Selection, interacting with sexual recombination, tends to impose relative uniformity at the functional level in complex adaptive designs, suggesting that most heritable psychological differences are not themselves likely to be complex psychological adaptations. Instead, they are mostly evolutionary by-products, such as concomitants of parasite-driven selection for biochemical individuality. An evolutionary approach to psychological variation reconceptualizes traits as either the output of species-typical, adaptively designed development and psychological mechanisms, or as the result of genetic noise creating perturbations in these mechanisms.  相似文献

Expectancy models of alcohol use   总被引:4,自引:0,他引:4  
The primary goal of the present article is to compare expectancy models with competing attitude models of alcohol use. First, several methodological issues in expectancy research were addressed, to more adequately compare the theoretical models. Study 1 examined the effect of possible self-report biases on associations among expectancy constructs and alcohol use. In Studies 2 and 3, the basic distinction between general factors of positive and negative alcohol expectancies was investigated in both cross-sectional and prospective models. Alternative predictions that were based on competing expectancy and attitude theories were evaluated primarily in Study 3. Results from these studies supported the validity of the expectancy constructs and the proposed distinctions among expectancy and attitude constructs-in terms of strong discriminant validity, absence of self-report bias, and differential prediction of alcohol use. Furthermore, the findings favored certain expectancy models over alternative attitude models of alcohol use, reaffirming the usefulness of the expectancy framework.  相似文献

Personality Correlates of Confidence in One's Decisions   总被引:2,自引:0,他引:2  
ABSTRACT Taylor and Brown (1988) hypothesized that certain illusions, such as unrealistic optimism, are predictably associated with positive affect, social skills, and intellectual functioning. To test this hypothesis, we obtained data from 162 students who first filled out a questionnaire containing dispositional measures of affect, social skills, and approaches to problem solving; in a second session they completed three tasks requiring difficult decisions, reporting their confidence in each decision. Accuracy of judgments was found to vary considerably from task to task, but confidence ratings showed a consistent pattern of individual differences. This result lent support to Taylor and Brown's hypothesis, as did other features of the data, most notably several small but significant Pearson r s between confidence ratings and dispositional variables. Removing the effects of accuracy from these r s reduced their magnitude very little; it yielded partial r s interpretable as evidence that illusory confidence is associated with personality traits which, in this case, load saliently on factors labeled ( a ) affective, and ( b ) cognitive/social.  相似文献

We propose that a preference for favorable social feedback (i.e., self-enhancement) requires only that feedback be characterized as favorable or unfavorable but that a preference for self-confirming feedback (i.e., self-verification) is based on a more elaborate set of cognitive operations that requires both the characterization of feedback and a subsequent comparison of that feedback to a representation of self stored in memory. Study 1 set the stage for testing this hypothesis by showing that depriving people of processing resources interfered with their tendency to access their self-conceptions. In Studies 2 and 3, participants who were deprived of resources preferred the favorable, self-enhancing evaluator, whereas control participants displayed a preference for the self-verifying evaluator, even if that evaluator was relatively unfavorable.  相似文献

Social support and immune function among spouses of cancer patients   总被引:8,自引:0,他引:8  
This study investigated whether social support was related to immune function among spouses of cancer patients. Effects of depression and negative life events were examined as potential mediators. Results showed evidence of greater immunocompetence on 2 of 3 dynamic measures: natural killer cytotoxicity and proliferation response to phytohemagglutinin among spouses who reported high levels of social support. All six components of social support assessed by the Social Provisions Scale (Cutrona & Russell, 1987) were strongly related to these indices of immune function. No evidence was found for mediation by either life events or depression.  相似文献

Current methods for assessing the quality of internalized object representations have not provided a continuous variable that simultaneously includes both an accuracy and a maturity component. A modification of Blatt, Brooks, Brenneis, and Schimek's (1976) Concept of the Object on the Rorschach scale that would combine the two components by weighting the quality of each response according to its form level was proposed. Initial discriminant and convergent validity of this modification was checked through correlations and multiple regression analyses using behavioral, diagnostic, and demographic data from 84 adolescent inpatients as dependent variables. Results indicate the modified score was directly related to measures of peer relatedness, intelligence, psychological health, and reality testing, and indirectly related to measures of psychosis and hostile, unmanageable behavior. The results support the utility of the modification for providing a continuous score that assesses both developmental maturity and accuracy, the two dimensions on which the concept of object representation is based.  相似文献
