Køppe’s proposition of four layers in theoretical building are used here in the exploration of a specific case of eclectic combination, the use of Piagetian and Vygotskian general approaches to the analysis of proportional reasoning as a cognitive mathematical ability. It is proposed here that the eclectic consideration of these contributions depends on the consideration of their specificity, in the sense that they highlight different aspects of the phenomenon under scrutiny, and also on the consideration of the coherence between this eclectic convergence and premises in terms of schools of thought under which each contribution is framed. We conclude proposing in accordance to S. Køppe’s proposal that eclecticism can be valuable and heuristic in theory development, but this contribution will depend largely on the effort in establishing careful relations between the four layers of theory-building.  相似文献

In this study we examined the congruence between partners’ perceptions of their marital relationship during the transition to parenthood and the effect of depression during pregnancy on couples’ congruence during the early postpartum period. Thirty-one couples who conceived spontaneously, along with thirty-five who conceived through assisted reproductive technologies (ART), provided data on their marital relationship and depression at their 24th pregnancy week and four months after the partum. All couples reported a decrease in marital congruence. Couples who conceived through ART reported lower marital congruence. For these subjects, women’s depression was associated with lower congruence. Interventions that focus on strengthening the marital relationship across the transition to parenthood should assess and promote couples’ congruence.  相似文献

Breakdown of foster care has been defined as the situation in which one of the involved parties terminates the intervention before having achieved the goals established for the case plan. This work presents a study carried out with a Spanish sample of 318 closed cases of children who were placed in foster homes and kinship care. The data were collected through the exhaustive review of the child protection and foster placement files, complemented with interviews of the welfare workers in charge of each case. The rate of breakdown of the entire sample was 26.1%, although it was significantly different in kinship care (19.7%) and foster care (31.2%). The results of this study indicate that the variables related to breakdown depend on the placement modality, either in foster care or kinship care. In the first case, the variables related to the child's characteristics are noteworthy, especially behavior and academic problems, with special relevance in the 9-12-year-old group, and in children who were previously in residential care. In contrast, in kinship care, the parents' problems (prison, mental health) and having some measure of guardianship are the most important. The fact of undergoing foster placement after having lived in various residential homes is transcendental. Lastly, the availability of economic resources and even the foster carers' studies seem to be related to foster breakdown.  相似文献

The aim of this paper is to discuss Charles’s (2011) attempt to turn E.B. Holt’s theoretical approach into the only possible bridge to connect Gibsonian ecological psychology with social psychology. Criticism of Charles’s claims is carried out at four different conceptual levels: historiographical, logico-epistemological, methodological, and theoretical. From this critical perspective, Charles’s resort to Holt’s ideas is viewed as an effort to legitimate Charles’s own line of work. Moreover, far from being this the only possible approach to the subject, many other rich alternatives to the application of Gibsonian principles to the explanation of socio-cultural phenomena already exist. In fact, it is questionable whether Holt’s behavioral neorealism allows dealing with many of the most complex socio-cultural issues, particularly those related to purposive behavior and intersubjective contexts. In order to address these questions from a Holtian point of view, Charles is forced to make a number of argumentative leaps and epistemological transgressions. In the last analysis, his insistence on keeping to the Holtian stance leads him to lose sight of the Gibsonian framework and to modify the very nature of his object of study, the social phenomenon—which, along the lines of classic neorealist behaviorism, becomes reduced to a simple consideration of behavioral purposiveness.  相似文献

Three adult male sex offenders with developmental disabilities participated in an evaluation of presession factors that may influence levels of sexual arousal measured with a penile plethysmograph. We evaluated the effects of presession masturbation (1 participant) and arousal-suppression strategies (2 participants). Results showed that presession masturbation lowered arousal levels and both participants suppressed arousal to varying degrees. These outcomes suggest the potential for consideration and manipulation of presession factors as treatment components for sex offenders with developmental disabilities.  相似文献

This study is an investigation of the impact of familial amyloid polyneuropathy type I (FAP I, ATTR V30M) on death anxiety and symbolic immortality. Templer and Drolet’s scales were administered to 524 individuals: (1) 84 relatives at risk, (2) 92 relatives not at risk for FAP I; and (3) a control group (n = 348) with no known hereditary disease in their families. At-risk relatives had, on average, a higher score for death anxiety and a lower score for symbolic immortality, than either those not-at-risk or controls. There were no significant differences in scores on either measure for those not-at-risk versus controls. Being at risk increases death anxiety and threatens the sense of symbolic immortality and psychosocial wellbeing. This may be true for other serious hereditary disorders as well. Genetic counsellors should become familiar with these concepts, feel comfortable initiating discussions about death with their patients, and be able to identify and reinforce their patients’ and family members’ sense of symbolic immortality.  相似文献

There are few studies on the development of anxiety and depression in orthopaedics and trauma (O&T) inpatients. We designed a cross-sectional study aimed at comparing the prevalence of depression and anxiety in 100 O&T inpatients and 100 clinical inpatients in the same hospital. O&T patients were divided into subgroups: trauma and non-trauma (arthroplasty, tumour, and infection sub grouping). We measured anxiety and depression by the Hospital Anxiety and Depression Scale and co-morbidities by the Charlson age-adjusted comorbidity index (CCI). For the trauma subgroup, AO/OTA fracture classification and Gustillo and Anderson grade of open fractures classification was applied. The prevalence of anxiety and depression was 35% and 28%, respectively for the clinical sample, and 44% and 33% for the O&T sample. Compared with the clinical sample, anxiety scores were higher in the O&T sample (p = .047), and in arthroplasty (p = .020) and trauma subgroups (p = .031). In the O&T sample, high CCI scores were associated with high anxiety scores (p = .033).  相似文献
