The (univariate) isotonic psychometric (ISOP) model (Scheiblechner, 1995) is a nonparametric IRT model for dichotomous and
polytomous (rating scale) psychological test data. A weak subject independence axiom W1 postulates that the subjects are ordered
in the same way except for ties (i.e., similarly or isotonically) by all items of a psychological test. A weak item independence
axiom W2 postulates that the order of the items is similar for all subjects. Local independence (LI or W3) is assumed in all
models. With these axioms, sample-free unidimensional ordinal measurements of items and subjects become feasible. A cancellation
axiom (Co) gives, as a result, the additive isotonic psychometric (ADISOP) model and interval scales for subjects and items,
and an independence axiom (W4) gives the completely additive isotonic psychometric (CADISOP) model with an interval scale
for the response variable (Scheiblechner, 1999). The d-ISOP, d-ADISOP, and d-CADISOP models are generalizations to d-dimensional dependent variables (e.g., speed and accuracy of response).

The study investigated whether the Stroop interference effect could be found in nonpatients with a self-report consistent with a diagnosis of bulimia nervosa. The nonpatient bulimic group showed significantly more interference to disorder-specific words (food, weight, and body shape) than to control words. The two nonpatient comparison groups, a depressed-nonbulimic group and a nonbulimic-nondepressed group, showed no interference. These results indicate that nonpatients with bulimia nervosa can be used to test various models of the cognitive and emotional processes involved in bulimia nervosa with the modified Stroop task. Methodological issues in the use of the computerized Stroop task with clinical populations are also noted. 相似文献

This study explored counselors’ conceptualization and use of encouragement as a therapeutic tool. Responses to two questions from 100 South Korean youth counselors were analyzed using consensual qualitative research–modified. As a result, six categories emerged under each domain. Implications for counseling and future studies are discussed. Este estudio exploró la conceptualización y el uso del apoyo como herramienta terapéutica por parte los consejeros. Usando el método modificado de investigación cualitativa consensual, se analizaron las respuestas proporcionadas a dos preguntas por 100 consejeros surcoreanos que trabajan con jóvenes. Como resultado, surgieron seis categorías bajo cada dominio. Se discuten las implicaciones para la consejería e investigaciones futuras. 相似文献

This paper identifies several kinds of intellectual mistakes that proponents of genetic engineering make, in defending their views and characterizing the views of their opponents. Results from research in the social sciences and humanities illuminate the nature of these mistakes. The mistakes themselves play a role in allowing proponents to gather support from other protagonists in the social controversies involving science and technology. Understanding the controversies requires understanding that innovations are components of complex and ill-structured social problems; the "right answer" does not follow from scientific or technological breakthroughs. If the problems are identified correctly, issues of non-economic or non-market values and political and individual rights will need to be addressed. 相似文献

In Hungary, there has been limited public debate about genetically modified crops, unlike in some Western countries. The mass media has published little to inform Hungarian lay people about genetically modified (GM) crops or their relevance to the country. Nevertheless, the media did convey some general impressions, mainly from within an Anti-GM Threat framing of the issue. This mass media frame was evident in lay focus group discussions—e.g. GM crops branded a food risk, general focus on risks, health risk identified as important risk, foreign companies regarded as source of the problem and as being ‘just out for profit’, image of corn, rhetoric of deterioration, etc. This overlap supports theories which suggest that media framings provide a resource which can be appropriated for public understanding. At the same time, however, dominant media framings were also mentioned only vaguely or in a somewhat modified way. Other issues raised in the media framing, not resonating with wider cultural themes, were absent from focus group discussions (e.g. environmental concerns). And participants were also able to rely on other conversational resources (analogous reasoning and cultural themes) to formulate some additional issues beyond the media reportage. 相似文献

Maternal touch and infants' self‐regulatory behaviours were examined during a modified Still‐Face with Touch (SF + T) procedure. Mothers and their 5½‐month‐old infants participated in one period of Normal interaction followed by three SF + T periods. Maternal functions of touch, and infants' self‐regulatory behaviour, affect, and attention were evaluated. Contrary to a typical SF procedure, the amount of smiling remained high while fretting remained low. High levels of maternal touching and variations in the functions of maternal touch were observed across periods. Playful touch remained high while there was an increase in nurturing touch and a decrease in attention‐getting touch from the Normal to all SF + T periods. Similar amounts of self‐regulatory behaviours were observed across periods with the exception of a decrease in bidirectional exchanges during the SF + T periods. Finally, across periods, maternal touch and infants' self‐regulatory behaviours were found to be temporally organized with infants' affect and attention. Examining how mothers use touch when other forms of communication are absent increased our understanding of the role of touch in infants' emotion regulation.

Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M‐SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M‐SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M‐SOS. We subsequently implemented ABA with the children for whom M‐SOS was not effective and observed a potential treatment generalization effect during ABA when M‐SOS preceded ABA. 相似文献

To reduce energy consumption, technical equipment alone is not sufficient. Adjustment of behaviours so that equipment is used appropriately is also necessary. Numerous studies have shown how difficult it is to change behaviours and how many factors are involved. The aim of this study is to identify the psychosocial factors facilitating or inhibiting energy‐saving behaviours in the appropriation of energy‐saving equipment by residents. Forty‐one semi‐directive interviews were conducted with tenants of terraced houses (12 people) and flats (29 people) located in the same residential area in a French city. The blocks of flats and terraced houses are managed by a proprietor of social housing. The results of a categorical content analysis highlight the importance of the relationship between tenants and proprietor and tenants' low motivation concerning the energy‐saving renovations. Consequently, we argue for the importance of favouring active participation by tenants in order to promote acceptance and appropriation of the new equipment. Furthermore, both the social and physical contexts of residents must be taken into account and energy saving must be integrated into other types of environmental behaviours in the neighbourhood in order to improve coherence and credibility.
