How does improving children's ability to label set sizes without counting affect the development of understanding of the cardinality principle? It may accelerate development by facilitating subsequent alignment and comparison of the cardinal label for a given set and the last word counted when counting that set (Mix et al., 2012). Alternatively, it may delay development by decreasing the need for a comprehensive abstract principle to understand and label exact numerosities (Piantadosi et al., 2012). In this study, preschoolers (N = 106, Mage = 4;8) were randomly assigned to one of three conditions: (a) count‐and‐label, wherein children spent 6 weeks both counting and labeling sets arranged in canonical patterns like pips on a die; (b) label‐first,wherein children spent the first 3 weeks learning to label the set sizes without counting before spending 3 weeks identical to the count‐and‐label condition; (c) print referencing control. Both counting conditions improved understanding of cardinality through increases in children's ability to label set sizes without counting. In addition to this indirect effect, there was a direct effect of the count‐and‐label condition on progress toward understanding of cardinality. Results highlight the roles of set labeling and equifinality in the development of children's understanding of number concepts.  相似文献

Little systematic information exists about how community‐based prevention efforts at the state and local levels contribute to our knowledge of intimate partner violence (IPV) prevention. The Centers for Disease Control and Prevention's (CDC) DELTA FOCUS program funds ten state domestic violence coalitions to engage in IPV primary prevention through approaches addressing the outer layers of the social ecology. This paper explored the ways in which DELTA FOCUS recipients have contributed to a national‐level dialogue on IPV prevention. Previously undefined, the authors define national‐level dialogue and retrospectively apply the CDC Science Impact Framework (SIF) to describe contributions DELTA FOCUS recipients made to it. Authors conducted document review and qualitative content analysis of recipient semi‐annual progress reports from 2014 to 2016 (= 40) using NVivo. A semi‐structured coding scheme was applied across the five SIF domains: Creating Awareness, Catalyzing Action, Effecting Change, Disseminating Science, and Shaping the Future. All recipients sought to promote IPV prevention by communicating and sharing with non‐CDC‐funded state coalitions, national partners, and other IPV stakeholders information and resources accumulated through practice‐based prevention efforts. Through implementing and disseminating their prevention work in myriad ways, DELTA FOCUS recipients are building practice‐based evidence on community‐based IPV prevention.  相似文献

Experiences of and responses to bodily symptoms have long held interest, from earlier roots in hysteria to the most recent category of somatic symptom disorder (SSD) in DSM 5. SSD’s focus on distress implies that symptoms hold meaning for individuals. This study used a psychoanalytically-informed, multiple interview method and analysis to explore such possible meanings. Six participants were interviewed on three occasions each, with four themes emerging as follows: (1) a foreign body in charge; (2) left alone with the foreign body; (3) the body works for the mind; and (4) the body mirrors the mind. Bion’s idea of an active container-contained function and the construct of psychic pain formed a useful framework for understanding themes. The distress that lies in somatic symptoms was formulated as potentially stemming from an initial difficulty with containment in the primary object relationship. It is argued that distress may indicate a struggle with suffering that is not only somatic but also psychological in nature; and that the symptomatic body may have reached its limits in containing psychic pain. Implications for working clinically include the importance of close and sustained attention, through the clinician’s reverie, to somatic and emotional feeling states to help guide treatment.  相似文献

Classroom discussion practices that can lead to reasoned participation by all students are presented and described by the authors. Their research emphasizes the careful orchestration of talk and tasks in academic learning. Parallels are drawn to the philosophical work on deliberative discourse and the fundamental goal of equipping all students to participate in academically productive talk. These practices, termed Accountable TalkSM, emphasize the forms and norms of discourse that support and promote equity and access to rigorous academic learning. They have been shown to result in academic achievement for diverse populations of students. The authors outline Accountable Talk as encompassing three broad dimensions: one, accountability to the learning community, in which participants listen to and build their contributions in response to those of others; two, accountability to accepted standards of reasoning, talk that emphasizes logical connections and the drawing of reasonable conclusions; and, three, accountability to knowledge, talk that is based explicitly on facts, written texts, or other public information. With more than fifteen years research into Accountable Talk applications across a wide range of classrooms and grade levels, the authors detail the challenges and limitations of contexts in which discourse norms are not shared by all members of the classroom community.

This study used the theory of planned behavior (TPB) to examine the impact of moral concerns on intention to buy organic apples and organic pizza. Initially, beliefs were elicited from a group of 30 people using a combination of the traditional TPB elicitation technique supplemented by direct questioning about emotions associated with the behavior. The questionnaire—which included measures of behavioral beliefs, attitudes, subjective norm, perceived behavioral control, and measures of moral norms (worded both positively and negatively)—was completed by 281 people. Multiple regressions showed that for both foods, the positive moral component added significantly to the prediction of intention, while negative ones did not. Also, affective attitude was a strong predictor of intention for both foods.  相似文献

Recent research suggests that social perceivers’ dispositional inferences are influenced by information about the ways others’ behavior varies stably across situations. We extend this research to stereotypes. Specifically, we examined peoples’ preconceptions about the situation–behavior profiles that social groups are likely to display, as well as the implications of such preconceptions for behavioral judgments. Focusing on gender stereotypes, in Study 1 we found that perceivers’ expectations about men’s and women’s assertiveness are qualified by situational information. Study 2 revealed that perceivers’ beliefs about the mentalistic attributes (e.g., goals, beliefs, motivations) that characterize men and women mediated the relationship between target gender and perceivers’ expectations about situation–behavior patterns. Study 3 explored how such contextualized stereotypes affect on-line judgments of targets’ behavior, showing that perceivers judge a given behavior’s assertiveness based not only on target gender but also on situation type.  相似文献

Studies of youths in residential treatment that utilize systematic assessments and validated measures are rare. We examined psychopathology, family characteristics, occurrence of physical or sexual abuse, types of aggressive behavior, hyperactive/impulsive behavior, medical and neurological problems, and self-reported drug and alcohol use in 397 youth who were assessed using reliable measures and consecutively treated in a residential treatment center. Results indicate high rates of internalizing and externalizing psychopathology, aggressive behavior, and consistent gender differences, with girls having higher levels of internalizing and externalizing psychopathology and aggressive behavior. The sample was characterized by high rates of medical problems including asthma, seizures, and obesity, as well as evidence of extensive family dysfunction, including high rates of parental alcohol use, violence, and physical or sexual abuse. Residential treatment needs to progress beyond the one size fits all approach and develop more specific and empirically proven treatments for the specific needs of this population.  相似文献

A previous investigation of individual differences in cortical activation during smoking reported differential development of vertex CNV ‘O’ and ‘E’ wave components in introverted and extraverted smokers. In the present paper the frontal CNV recorded from 12 extraverted and 12 introverted smokers was analysed under simple and choice foreperiod conditions during sham and real smoking. Smokers were matched for age, sex and neuroticism. Analysis of variance revealed significant group by smoking session effects for the later ‘E’ wave component but not for the early ‘O’ wave component. ‘O’ wave negativity though more prominent in frontal regions particularly in extraverts tended to be more affected by foreperiod conditions than smoking sessions. In general smoking produced an increase in central negativity in extraverts, and a decrease in parietal positivity in introverts. These results challenge the stimulus-related/response-related separation of smoking effects made previously to account for early and late CNV component differences. It is suggested that a distinction of CNV components in terms of input (sensory) and output (motor) aspects may anyway be inappropriate.An attempt is made to relate CNV negativity/positivity topography differences to a motor model of attentional strategies differentially deployed during smoking. Extraverted smoker strategies may aim to relieve boredom, enhance readiness to act and so increase central negativity. Introverts may smoke to inhibit distraction, maintain a complex attentional set, and so these affect parietal positivity.It is further suggested that the pharmacological effects of nicotine are those of a generalized mild stressor which supplement the motor aspects of smoking in inducing more motivated performance. Some further predictions concerning the effect of smoking on cortical activity are discussed.  相似文献

The role of auditory and visual factors in short-term recall and recognition performance was evaluated. Auditory similarity, but not visual similarity, was found to be predictive of the probability of a correct response and response confidence for both types of tests. The results were interpreted as support for a single-trace model of recall and recognition performance.  相似文献
