Visual representations are prevalent in STEM instruction. To benefit from visuals, students need representational competencies that enable them to see meaningful information. Most research has focused on explicit conceptual representational competencies, but implicit perceptual competencies might also allow students to efficiently see meaningful information in visuals. Most common methods to assess students’ representational competencies rely on verbal explanations or assume explicit attention. However, because perceptual competencies are implicit and not necessarily verbally accessible, these methods are ill‐equipped to assess them. We address these shortcomings with a method that draws on similarity learning, a machine learning technique that detects visual features that account for participants’ responses to triplet comparisons of visuals. In Experiment 1, 614 chemistry students judged the similarity of Lewis structures and in Experiment 2, 489 students judged the similarity of ball‐and‐stick models. Our results showed that our method can detect visual features that drive students’ perception and suggested that students’ conceptual knowledge about molecules informed perceptual competencies through top‐down processes. Furthermore, Experiment 2 tested whether we can improve the efficiency of the method with active sampling. Results showed that random sampling yielded higher accuracy than active sampling for small sample sizes. Together, the experiments provide the first method to assess students’ perceptual competencies implicitly, without requiring verbalization or assuming explicit visual attention. These findings have implications for the design of instructional interventions that help students acquire perceptual representational competencies.  相似文献

We wished to examine determinants of suicidal behavior in prisoners. 903 male prisoners had a psychiatric interview which included various psychometric tests. Suicide attempters were compared with prisoners who had never attempted suicide. Significantly more of the attempters had a history of psychiatric disorder, substance abuse, a family history of suicidal behavior, convictions for violent crime, had exhibited aggressive behavior in jail, and had higher BGLHA aggression scores. A similar pattern of risk factors was found for prisoners with suicidal ideation. A lifetime history of attempting suicide, or of having suicidal ideation, is frequent in prisoners. Risk factors include family, developmental, aggression, personality, psychiatric, and substance abuse factors.  相似文献

Department of Educational Psychology, The Pennsylvania State University, University Park, Pennsylvania 16802 This study is a report of an investigation of the interaction between imagery ability and processes employed for facilitating recall. The tasks were assumed to involve contrasting processes through the use of imaginal or verbal mediators and concrete or abstract jingles (mnemonic aids) in memorizing two concrete and two abstract lists of 10 words in each list. The dependent variables were latencies in arriving at an association, number of errors and omissions on immediate recall, and number of errors and omissions on delayed recall. The main effects of imagery ability, favoring high imagers, and of kind of lists favoring concrete lists were significant. In delayed recall there was a significant interaction of mnemonic aid and kind of list. Imagery ability interacted with mediators to influence Ss’ recall. The results were discussed as supporting Paivio’s two-stage association model.  相似文献

Children's family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers and children (N = 1432 families) in 13 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand and United States) reported on their expectations regarding children's family obligations and parenting attitudes and behaviours. Within families, mothers and fathers had more concordant expectations regarding children's family obligations than did parents and children. Parenting behaviours that were warmer, less neglectful and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children's family obligations between families within cultures as well as between cultures. These international findings advance understanding of children's family obligations by contextualising them both within families and across a number of diverse cultural groups in 9 countries.  相似文献

A longitudinal repeated measures design was used to investigate the influence of treatment retention, and membership turnover on individual outcomes, and the relationship between individual-level and group-level therapeutic alliance in rolling group psychotherapy for individuals with cocaine abuse disorder. Eighteen patients were studied; data were collected prior to therapy and then monthly for 24 months. Patient outcomes and process were assessed. Improvements in symptoms and psychological functioning were associated with retention in psychotherapy. Membership turnover had a negative influence on symptoms. Development of an individual alliance was affected by the development of group-level therapeutic alliance, but not by time spent in therapy.  相似文献

The significance of enhancing parenting skills to reduce child maladjustment is well-established and supports the important role of evidence-based parenting programs. However, the notion that parenting should be the exclusive focus for enhancing child behavior is necessarily limiting. Evidence is growing that relationship-oriented treatments may be another powerful approach to improve child adjustment, albeit the underlying effects in couple- versus parenting-focused programs have been subject to limited study. The aim of this RCT was to compare the treatment effects of (1) a couple-focused program (the Couples Coping Enhancement Training) to (2) a parenting training (Triple P) and (3) a control group on children’s behavioral problems in 150 couples. The parents’ perceptions of relationship quality, parenting behavior, and child’s behavioral problems were assessed by means of questionnaires completed prior to and 2 weeks after the end of the treatment. Multi-group path analyses revealed that in mothers’ perception the couple-focused program reduced child behavioral problems by enhancing the relationship quality whereas improved parenting mediated the benefits in the parenting training. In fathers’ evaluations the couple-focused program reduced dysfunctional parenting which largely accounted for the benefits in child adjustment. The dearth of research on child outcomes in couple-focused intervention studies is a striking gap that should be overcome. It is a promising field because of its evident potential to foster the health of many children.  相似文献

This article follows a previous study that has recently been published in Narrare I Gruppi and explored the reasons for the large numeric gap between the regions of the North and South of Italy, referring to the breast cancer screening program adherence rate sponsored by the Italian Healthcare System, that addresses all women living in Italy ranging in age between 48 and 69 years, and proposes a free mammogram every two years. The effectiveness of cancer early detections has been widely demonstrated by medical research; this kind of diagnosis is particularly important in the case of breast cancer. A diagnosis of this form of cancer at its early phases in 97% of cases allows women to survive at least five years after it. However, the different level of trust women feel for healthcare structures is the discriminating element between the North and South of Italy for their access to the screening program. This topic will be thoroughly analyzed by presenting the results of research aimed at evaluating the meaning given to the outcomes of a first exploratory study, this second study also offers the opportunity to share our results within the social context that has generated them. The outcomes of the present research have been presented to a group of “privileged witnesses” living in the South (Naples and its surroundings): 12 women aging from 49 to 65, and 5 healthcare workers (one doctor, 25 two nurses, and two Local Health Authority supervisors); they took part in three Focus Groups for an in-depth look of the theme in question. The analyses of the groups' debates, carried out by means of a software for text analysis (T-LAB), confirmed the results of the previous research: the diffidence and lack of synergy between institutions and healthcare workers are the causes of southern women's lack of participation to the breast cancer screening program. In particular, the comparison between women's and workers' viewpoints shows a different emotional connotation about the possibility to improve participation to the screening: the workers' optimism countervails women's distrust and pessimism.  相似文献

Although several studies have shown a clear association between childhood adversities and later development of a number of psychiatric disorders, a number of recent reports have cast doubts regarding the aetiological role played by abuse, neglect and loss, arguing that they are neither necessary nor sufficient to account for the development of subsequent psychopathology. In this study, we aimed to investigate the associations and predictive power of childhood adversities on later onset of Axis-I &-II psychiatric conditions and the impact on severity of psychiatric presentation in a large sample of patients. This cross-sectional multi-centre study evaluated patients (N = 1136) recruited in fourteen NHS psychotherapy departments in the UK. Patients were assessed using a number of rater-based questionnaires and self-rated measures. Multiple regression analyses showed that childhood experiences of loss and physical abuse were predictive of severe personality disorder and borderline personality disorder, but not of other less severe PD and Axis-I diagnoses. Sexual abuse predicted later onset of Post-traumatic Stress Disorder. In addition, we found that childhood abusive experiences were strongly associated with severity of psychiatric distress, interpersonal problems and global functioning. Having experienced two or more childhood adversities significantly increased severity of psychiatric distress, interpersonal malfunctioning and CORE scores.  相似文献
