拖延对工作绩效的影响——压力偏好与任务类型的调节作用

本研究探索了压力偏好和任务类型在拖延行为对绩效产生作用过程中的调节作用。用问卷调查的方法对155人进行调查。结果发现：相比偏好压力者,厌恶压力者的工作绩效更容易受到拖延行为的影响;对于复杂任务,拖延对偏好压力者的绩效影响显著低于对厌恶压力者;而对于简单任务,两种类型人的绩效的差别并不明显。结论是,偏好压力者能够减弱拖延行为对其工作绩效的影响,尤其对于复杂任务,这种影响更加明显。     

人类对知识的好奇:认识性好奇心

认识性好奇心是个体对新知识的好奇,可从状态和特质角度理解,其中特质认识性好奇心又区分为兴趣型和剥夺型两种类型。近年来众多证据表明,认识性好奇心受知道感、性别、对信息的偏好模式等因素影响,并在学习、记忆及创造性方面起到积极作用。未来研究有必要着眼于毕生发展的角度进行纵向考察,完善其测量方式,并深入考察认识性好奇心对学习的影响机制,从而为教育实践提供一定启示。     

Human-introduced long-term traditions in wild redfronted lemurs?

Behavioural traditions have only been described for a small subset of species, and the factors responsible for the maintenance of traditions over time are unclear. Redfronted lemurs are known to learn socially but traditions have not been described in the wild. We conducted a social diffusion experiment over three experimental years with artificial feeding boxes that could be opened in two different ways (pushing or pulling a door). Six out of 14 individuals that participated in at least 2 years exhibited a stable preference: five lemurs maintained a pull and one lemur a push preference, suggesting that habit formation and reinforcement learning may have lead to preferences over time. The remaining individuals exhibited fluctuating preferences and switched between showing a preference or no preference, but never switched between preferences. This instability might have been due to the low level of difficulty and/or the low object specificity of the task. The majority of lemurs additionally scrounged. Scrounging was not influenced by age, sex or success in manipulating the boxes. Thus, redfronted lemurs appear to use the two techniques flexibly but also scrounged opportunistically to get access to the rewards, indicating that traditions might be stabilized by multiple factors.

Exploratory factor analysis of the Human Behavior Rating Scale: a rural population

The construct validity of Eaves' Human Behavior Rating Scale (HBRS) was investigated. The HBRS is a scale with 91 Likert-type items designed to measure five factors: arousal (persistence and curiosity), affect (externalizing and internalizing), and cognition. Forty-four teachers of Grades 6, 7, and 8 from two low socioeconomic and rural southern counties completed the HBRS for 320 of their students. Three parcels were submitted for analysis for each of the five dimensions. A five-factor, then a two-factor, solution were analyzed using exploratory factor analysis. A principal-axis factor analysis was employed and an oblique promax rotation was applied. The results supported the five-factor solution with 90.2% of the total variance accounted for when compared to the two-factor solution which recovered 73.4% of the total variance. Intercorrelations between factors ranged from .15 to .76 for the five-factor solution.     

EARLY EXPERIENCE AND EXPLORATIVE BEHAVIOR IN THE WHITE RAT

Eleven rats were reared in a cage with moving figures. Eleven litter mates were reared in a similar cage but without figures. The rats from the more complex environment showed less locomotor activity in a checkerboard maze and, in a two-lever test box, higher preference for the lever which produced complex visual stimuli. It is proposed that rearing in stimulus poverty increases locomotor activity and reduces curiosity.

The measurement and conceptualization of curiosity

In this study, the authors tried various methods to measure and conceptualize curiosity. A sample of 369 education students (103 men, 266 women) who were attending universities on the East Coast of the United States completed 5 paper-and-pencil curiosity measures in 1 of their classes. Using confirmatory factor analysis, the authors found that the data best fit a 3-factor curiosity model consisting of cognitive curiosity, physical thrill seeking, and social thrill seeking. These findings supported the development of new instruments that specifically measured those 3 curiosity types, new empirical research predicting meaningful curiosity-related outcomes, and subsequent theory building concerning how and why curiosity is a fundamental part of optimal human functioning.     

Specific and diversive curiosity and depression in junior high school students of divorced and nondivorced parents.

124 junior high school students (Grades 5 to 8) from a small school district in north central Kansas completed the Beck Depression Scale, the Maze test, and the Which-to-Discuss test. Background information, such as age, sex, grade, and marital status of parents, were also collected. There were no significant differences between boys and girls of divorced and nondivorced parents or across grades for scores on the Which-to-Discuss (specific curiosity) and depression, but boys scored significantly higher on the Maze test (diversive curiosity). No differences were noted between the students of divorced and nondivorced parents or across grades. Scores on Which-to-Discuss test and Maze test were not significantly correlated, but scores on one Maze test and depression correlated positively and significantly. When these students scored as more depressed, although in the normal range, they tended to score higher on diversive curiosity.     

Fear selectively modulates visual mental imagery and visual perception

Preferences for faces are thought to be the result of either general adaptations for mate selection, and thus influenced by sexual dimorphism, or mechanisms of general information processing and thus nonspecific to faces. If mate choice determines face preference then it should follow that the sex of a face should affect attractiveness judgements. To test this idea we used image morphing to generate three versions of face images: original, opposite sex, and antiface. First we established that the sex of the face was identifiable in our images. We then collected attractiveness ratings for the three face types. We found that attractiveness ratings to the original faces were correlated with, and did not differ significantly between, ratings to the opposite-sex faces. However, ratings for either the original or opposite face types were not correlated with and were significantly lower than ratings to the antifaces. Our findings failed to support the idea that attractiveness is related to sexual dimorphism in faces alone but suggest instead that other more generic factors influence preferences for all faces.     

Etiology of obsessions and compulsions: a behavioral-genetic analysis

It is unknown whether various types of obsessive-compulsive (OC) symptoms have a common genetic or environmental etiology. For example, it is unknown whether hoarding is etiologically associated with prototypic OC symptoms, such as washing, checking, and obsessing. Also unknown is whether particular OC-related symptoms are etiologically linked to the general tendency to experience emotional distress (negative emotionality). To investigate these and other issues, a community sample of 307 pairs of monozygotic and dizygotic adult twins provided scores on 6 OC-related symptoms (obsessing, neutralizing, checking, washing, ordering, and hoarding) and 2 markers of negative emotionality (trait anxiety and affective lability). Genetic factors accounted for 40%-56% of variance in the 8 phenotypic scores (M = 49% of variance for OC-related symptoms). Remaining variance was due to nonshared (person-specific) environment. More detailed analyses revealed a complex etiologic architecture, where OC-related symptoms arise from a mix of common and symptom-specific genetic and environmental factors. A general genetic factor was identified, which influenced all symptoms and negative emotionality. An environmental factor was identified that influenced all symptoms but did not influence negative emotionality. Each of the 6 types of symptoms was also shaped by its own set of symptom-specific genetic and environmental factors. The importance of genetic factors did not vary as a function of age or sex, and the architecture of general and specific etiologic factors was replicated for participants having relatively more severe OC symptoms. Gene-environment interactions were identified. Implications for an etiology-based classification system are discussed.     

Sex differences in rats' response to novelty measured by activity and preference

Rats were familiarized to one compartment of a test box and then given access to this and a novel compartment. Females spent more time in the novel compartment than males did and this difference was found to be independent of a possible difference in familiarity with the familiar compartment arising from the females' higher frequency of ambulating and rearing with sniffing during familiarization. This is evidence of a sex difference in response to novelty independent of activity differences. Females also had shorter approach latencies to the novel compartment. These sex differences could reflect differences in either fearfulness or curiosity.     

JOB ORIENTATION OF MALES AND FEMALES: ARE SEX DIFFERENCES DECLINING?

Sex differences in job orientation found by Manhardt (1972) were explored to determine if they still exist, or if a trend toward similarity as found in studies on traits and behaviors prevails. Significant sex differences were found on 8 of 25 job characteristics, compared with 11 found by Manhardt. In the original study, factor analysis indicated that males value long-range career objectives while females prefer a comfortable working environment and pleasant interpersonal relationships. This study extracted similar factors which explained twice the variance found in the original. However, sex differences on factor preference were mixed. Further, results show that males are less homogeneous in their preference than are females, a complete reversal of results found previously. Implications for personnel managers in handling differences on job orientation of males and females are discussed.     

A Conceptualization of Entrepreneurial Curiosity and Construct Development: A Multi-Country Empirical Validation

The purpose of this article was to fill a gap in the literature regarding the conceptualization and measurement of entrepreneurial curiosity. Although research in other fields suggest that different types of curiosity exist, no conceptualization research has yet been done in the field of entrepreneurial curiosity. This research aimed to develop a construct of entrepreneurial curiosity and tested it on multi-country empirical samples (Slovenia and the United States). Items for the questionnaire were developed after an in-depth literature review and detailed interviews with entrepreneurs and experts in two stages. The data from the survey were analyzed using exploratory and confirmatory factor analysis. The results of this study showed that entrepreneurial curiosity can be an independent construct dimension in relation to other types of curiosity. Entrepreneurial curiosity can be used as a new concept and measure in research. The construct can be tested on a sample of nonentrepreneurs in a multi-country sample and together with other determinants in a future model. With the measure of entrepreneurial curiosity, society can test individuals and encourage them to become active in entrepreneurship.     

Measures of motivation

Tested four new scales and replicated earlier findings of the Orientation and Motivation Inventory with 159 boys and 166 girls in four grades of a high school. Each of the 12 scales was subdivided for analyses into two halves. The intercorrelations among the 24 scale halves were analyzed by the method of principal components to identify 11 factors for boys and 10 for girls. Ten of the twelve postulated dimensions were confirmed in the varimax solution for each sex. A factor analysis of the correlations among the 12 scale scores disclosed five similar second order dimensions for boys and for girls. These were hypothesized to reflect Status Seeking, Belief in own Potency, Seeking and Helping People, Theoretical Interests. and Risk-Taking preference.     

Preference for simple interval schedules of reinforcement in concurrent chains: Effects of segmentation ratio

A concurrent-chains procedure was used to examine pigeons' preferences between segmented and unsegmented terminal-link schedules of reinforcement. During the initial link, a pair of independent, concurrent variable-interval 60-s schedules was in effect. In the terminal link, reinforcement was provided by a chain fixed-interval fixed-interval schedule on one key and by a simple fixed-interval schedule with an equal interreinforcement interval in the other. The relative duration between the first and second components (segmentation ratio) in the terminal-link chained schedule was systematically varied while the terminal-link duration was kept constant at either 15 s or 30 s in two sets of conditions. With few exceptions, the simple schedule was preferred to the chained schedule. Furthermore, this preference was inversely related to the size of the segmentation ratio in the segmented schedule. When the segmentation ratio was smaller than 1:1, preference was more extreme for a 30-s condition than for a 15-s condition. However, preference decreased more rapidly in conditions with the longer terminal-link duration when the ratio increased. Taken together, these results were consistent with previous findings concerning the effect of the terminal-link duration on choice between segmented and unsegmented schedules. In addition, the data suggested that segmentation ratio in a segmented schedule constitutes another potent factor influencing preference for the unsegmented schedule.     

Measuring epistemic curiosity and its diversive and specific components

A questionnaire constructed to assess epistemic curiosity (EC) and perceptual curiosity (PC) curiosity was administered to 739 undergraduates (546 women, 193 men) ranging in age from 18 to 65. The study participants also responded to the trait anxiety, anger, depression, and curiosity scales of the State-Trait Personality Inventory (STPI; Spielberger et al., 1979) and selected subscales of the Sensation Seeking (SSS; Zuckerman, Kolin, Price, & Zoob, 1964) and Novelty Experiencing (NES; Pearson, 1970) scales. Factor analyses of the curiosity items with oblique rotation identified EC and PC factors with clear simple structure. Subsequent analyses of the EC items provided the basis for developing an EC scale, with Diversive and Specific Curiosity subscales. Moderately high correlations of the EC scale and subscales with other measures of curiosity provided strong evidence of convergent validity. Divergent validity was demonstrated by minimal correlations with trait anxiety and the sensation-seeking measures, and essentially zero correlations with the STPI trait anger and depression scales. Male participants had significantly higher scores on the EC scale and the NES External Cognition subscale (effect sizes of r =.16 and.21, respectively), indicating that they were more interested than female participants in solving problems and discovering how things work. Male participants also scored significantly higher than female participants on the SSS Thrill-and-Adventure and NES External Sensation subscales (r =.14 and.22, respectively), suggesting that they were more likely to engage in sensation-seeking activities.     

The relationship of sex role identity and social and politicalattitudes

A study is reported of the relationship between conscious social role preferences, unconscious sexual identifications, and attitudes toward five categories of social and political issues. Based on factor scores of inventory items, the categories include political liberalism, birth control, sex role morality, racial discrimination, and the achievement ethic The population studied consisted of men and women from communities designated working class, middle class, and upper class Controlling for the effects of age, sex, marital status, occupation, education, and political party preference, results indicate statistically significant associations between conscious and unconscious masculinity and femininity and attitudes toward all five categories of issues The patterns of associations, however, are not always consistent Discussion includes a consideration of sex role identity as a value and the implication of sex role differentiation for the integration of personality as well as social institutions     

Translation and preliminary validation of a Korean version of the parental reflective functioning questionnaire

This study aimed to explore the factor structure, reliability, and validity of a Korean translation of the Parental Reflective Functioning Questionnaire (PRFQ). The PRFQ consists of three subscales: prementalizing modes, certainty about mental states, and interest and curiosity in mental states. A convenience sample of 163 Korean parents completed the K‐PRFQ. Exploratory factor analysis showed three factors mapped on to the original PRFQ factors, but items from the original prementalizing modes subscale clustered into two additional factors. Data from a subsample (n = 67) showed that the certainty about mental states and interest and curiosity in mental states subscales correlated positively with more optimal self‐reported parenting. We discuss the validity of using the PRFQ in collectivistic cultures.
