Parental discipline and gender-role socialization are two interrelated normative processes that may be affected by family structure, parent gender, and child gender. To investigate these family processes and how they may differ depending on family composition, three groups of families (approximately 90% Caucasian) with 5-year-old children were studied: 67 two-parent families, 32 single-mother families, and 13 single-father families. In the two-parent families, mothers were focused on in 33 of the families and fathers were focused on in 34 of the families. Overall, gender-role socialization processes were affected by family structure and parent gender: Single-parent families and mothers had less traditional gender-role socialization than two-parent families and fathers. Family discipline processes were also affected by family structure, as single-parent families reported more positive behavior from their children and reported using more problem-solving strategies. Regardless of family structure, parents used different discipline strategies depending on the gender of parent and child. No evidence was found to suggest that gender-role socialization mediated the discipline process.

We examined relations between the environmental dimensions underlying Holland's theory of vocational choice and skill requirements, context characteristics, and task frequency ratings for managerial jobs. The Holland environmental constructs were measured by the recently developedPosition Classification Inventory(PCI). The task, skill requirement, and context variables were measured using traditional job analysis surveys. Ten judges provided estimates of the expected correlations between the job analysis variables and the Holland constructs. The profile of observed correlations was generally consistent with the judges’ expectations based on Holland's theory, providing support for both that framework and the construct validity of the PCI. The one Holland dimension for which the data were least consistent with predictions was “Realistic.” Results provide a detailed picture of the work content, skills, and context variables within managerial work that are likely to be associated with the RIASEC dimensions. Implications for management development are discussed.  相似文献

Six elementary-aged children were taught to spell words containing initial consonant clusters (CCs). They were trained to select printed words in response to the corresponding spoken words using computerized matching-to-sample procedures. After each training session, they were tested for spelling with a constructed-response transfer test. Based on previous selective stimulus control research, we hypothesized that only the first letter of an initial CC might control spelling when CC spelling errors are made. Thus, a critical-difference matching-to-sample training condition that required the children to respond to both letters of the CC to be correct was compared to a multiple-difference training condition that required the children to respond to only one letter of the pair. Results showed that children made fewer errors during the multiple-difference training condition than during the critical-difference training condition. On the constructed-response transfer tests, however, more overall errors and CC errors were made in the multiple-difference condition than in the critical-difference condition, and the words trained in the multiple-difference condition required more training sessions to reach criterion. All children improved their spelling of novel CC words by the completion of training. If normal classroom or home reading was to be supplemented by computer tasks of the kind used here, some spelling problems could be circumvented without costly intervention by a teacher or a special trainer.  相似文献

Skin-surface temperatures on thehuman hand were obtained immediately following six exposure times ranging from 5 to 60 sec. for water temperatures varying in 5° increments from 10° to 40°C. The surface of the skin was found to respond rapidly and regularly to both the temperature and time of exposure. In a second study 30 Ss exposed a hand for 5 or 30 sec. to water temperatures ranging from 10° to 45°C. and made ratings on scales of pain and comfort as well as attaching a verbal label (cold, cool, tepid, etc.) to each experience. The experience of cold became more intense over these time intervals while the experience of warmth became less, and with the threshold constant taken into account the sensations of pain and discomfort were found to follow a psychophysical power law. The usefulness of these sorts of data for interpreting the effects of noxious stimuli in basic learning studies is discussed.  相似文献

Understanding the complexity of religious transformation requires empirical contextualized research on the continuous dynamic relationship between formation and transformation. Narrative study in context unveils the implicit meaning of phenomena made explicit in stories. This article, through a biographical case study of a Mennonite woman’s religious journey, explores the complex nature of religious transformation with particular attention to intricate interplay of factors. Critical insights regarding the inseparable relationship between formation and transformation are made clear through an in‐depth examination of lived experience, yielding implications for religious education.  相似文献

In Jensen's theme paper she did an excellent job of outlining and explaining ways in which motor developmentalists can use the tools of biomechanics and engineering to address research questions. We extend her thorough efforts in two ways. First, we highlight the communication value provided by the precision of biomechanics terminology, and second, we reinforce the need to embed motion (the kinematics and kinetics) in context and function in order to understand the complexity of behaviour. We illustrate how one biomechanical tool, mechanical models, can facilitate this and provide insight to the development of control. Copyright © 2005 John Wiley & Sons, Ltd.  相似文献

Higher cognitive function is associated with faster choice reaction time (CRT), and both are associated with a reduced risk of mortality from all-causes and cardiovascular disease (CVD). However, comparison of the predictive capacity of CRT, an emerging risk factor, with that for established ‘classic’ risk factors for mortality, such as smoking, hypertension or obesity, is lacking. The purpose of this study was to compare the relative impact of CRT with a range of established risk factors for all-cause and CVD mortality. The UK Health and Lifestyle Survey (HALS) is a national sample survey of adults in England, Scotland, and Wales. In 1984/85, data on lifestyle factors, socioeconomic status, and health were collected for 9003 individuals. CRT data were available for 7414 individuals. With different predictor variables having differing coding structures, we used the relative index of inequality (RII) to explore the relation of a range of risk factors with mortality by computing the risk in disadvantaged (high risk; e.g., smokers) relative to advantaged (low risk; e.g., non-smokers) persons. During an average of 20 years of follow-up, there were 1289 deaths (568 ascribed to CVD). In age- and sex-adjusted models in which all-cause mortality was the outcome of interest, CRT mean (RII = 2.57, 95% CI = 1.98, 3.33) was the second most important predictor of death after smoking (RII = 3.03, 95% CI = 2.45, 3.75). For death from CVD, CRT mean (RII = 2.31, 95% CI = 1.55, 3.43) was again the second most important risk factor for death, behind systolic blood pressure (RII = 4.37, 95% CI = 3.03, 6.29). These analyses suggest that CRT, a moderately high correlate of intelligence, is an important risk factor for death from all-causes and CVD.  相似文献

Inattentional blindness is described as the failure to perceive a supra-threshold stimulus when attention is directed away from that stimulus. Based on performance on an explicit recognition memory test and concurrent functional imaging data Rees, Russell, Frith, and Driver [Rees, G., Russell, C., Frith, C. D., & Driver, J. (1999). Inattentional blindness versus inattentional amnesia for fixated but ignored words. Science, 286, 2504–2507] reported inattentional blindness for word stimuli that were fixated but ignored. The present study examined both explicit and implicit memory for fixated but ignored words using a selective-attention task in which overlapping picture/word stimuli were presented at fixation. No explicit awareness of the unattended words was apparent on a recognition memory test. Analysis of an implicit memory task, however, indicated that unattended words were perceived at a perceptual level. Thus, the selective-attention task did not result in perfect filtering as suggested by Rees et al. While there was no evidence of conscious perception, subjects were not blind to the implicit perceptual properties of fixated but ignored words.  相似文献

This report examines (1) the prevalence of dating violence victimization from a national sample of rural adolescents and (2) patterns by gender and region. Analyses are based on 20,274 adolescents who reported violence victimization using the Community Drug and Alcohol Survey. The relationship of dating violence with gender and region was assessed with HLM5 using Bernoulli's logistic regression. Approximately 16% of adolescents reported being a victim of dating violence. Females reported higher incidence of victimization than males. Dating violence is more prevalent in the South. While it is important to address the underlying values in society that may contribute to dating violence, it is equally productive to include regional and cultural values.  相似文献

The last decade or so has seen an increase in the rate of attention to systems change and the application of multiple theories to study and influence change in systems. This article considers how these theories, described in other articles in this issues, plus theories about complex adaptive systems open opportunities for us to continue to expand our repertoire of tools and methods to address systems change. These conceptual frameworks, tools, and methods are expected to help us increase our capacity to study and influence both planned and self-organizing systems change. New tools and methods have emerged and others are needed to help us continue to explore and influence the complex social systems within which we operate.  相似文献
