We sought to distinguish mastery goals (i.e., desire to learn) from performance goals (i.e., desire to achieve more positive evaluations than others) in the light of social judgment research. In a pilot study, we made a conceptual distinction between three types of traits (agency, competence, and effort) that are often undifferentiated. We then tested the relevance of this distinction for understanding how people pursuing either mastery or performance goals are judged. On self-perception, results revealed that effort was predicted by the adoption of mastery goals and agency by performance goals (Study 1). On judgments, results showed that (a) the target pursuing mastery goals was perceived as oriented toward effort, and (b) the target pursuing performance goals was oriented toward agency (Study 2). Finally, these links were shown again by participants who inferred a target’s goals from his traits (Study 3). Results are discussed in terms of the social value of achievement goals at school.  相似文献

A series of recent arguments purport to show that most counterfactuals of the form if A had happened then C would have happened are not true. These arguments pose a challenge to those of us who think that counterfactual discourse is a useful part of ordinary conversation, of philosophical reasoning, and of scientific inquiry. Either we find a way to revise the semantics for counterfactuals in order to avoid these arguments, or we find a way to ensure that the relevant counterfactuals, while not true, are still assertible. I argue that regardless of which of these two strategies we choose, the natural ways of implementing these strategies all share a surprising consequence: they commit us to a particular metaphysical view about chance.  相似文献

Play observations with a total of 400 toddlers and preschoolers were videotaped and rated for Intensity and Quality of play with their parents. Parents were asked about perceived stress and personality characteristics (Big 5). Child's motor, cognitive skills, temperament, and internalizing behaviors were assessed. Study 1 investigated the robustness of play across child age and gender, and examined differences between fathers and mothers. Study 2 explored the vulnerability of play with fathers of children born preterm (PT‐fathers) and fathers who had experienced adverse childhoods (AC‐fathers). Study 3 investigated child internalizing behaviors. Intensity of play was maintained almost independently of child age and gender. It was similar for AC‐ and PT‐fathers, and similar to maternal Intensity. In contrast, paternal Quality of play was higher with boys and independent of fathers’ personality and perceived parenting stress whereas maternal Quality of play was higher with girls and linked to mothers’ perceived parenting competence, acceptability of the child, and neuroticism. AC‐fathers scored significantly low on Quality, as did PT‐fathers, but the Quality of their play became better with growing child age, birth weight, and cognitive (but not motor and temperament) scores. Finally, child internalizing behaviors were negatively related to paternal Quality of play.  相似文献

This paper is an exploration into the question, “What does considering gestational life add to analytic theory and practice?” It attempts to situate prenatal experience in the psychoanalytic dialogue, to explore its place in subsequent mental life, to discuss how this may be useful in clinical process, and to reconceptualize some theory in light of a gestational perspective. Neuro-psychoanalytic theory is utilized with an emphasis on nonconscious mental process which takes the form of implicit memory, providing people with a sense of continuity and well-being or stress. Intra-uterine experience can include pain and suffering. Fetal stress is an integral part of prenatal development and its metaphorical use in clinical practice. Three concepts—gestational being/becoming, geatational holding, and objectless intersubjectivity—are offered as ideas to introduce order and conceptual clarity into the ineffable mysteries of in utero process. A gestational perspective is used to describe how the analyst intuitively tracks the patient’s sense of well-being/stress.  相似文献

We investigated the frequency of secondary school students’ self-reported cheating in mathematics and relationships between cheating and motivational beliefs, as well as neutralizing attitudes. Two types of cheating were examined: active cheating, which is aimed to increase a person’s own success, and second-party cheating, aimed to help other students achieve success. Students use second-party cheating very often and more than active cheating. Motivational beliefs are significantly related to active cheating but uncorrelated with second-party cheating. Thus, although active and second-party cheating are both classified as dishonest acts, they do not have the same motivational mechanisms in their background.  相似文献

The aims of this study were to document movement of genetic counselors (GCs) out of clinical positions and identify factors that might help employers attract and retain clinical GCs. A confidential on-line survey of GCs ever licensed in the state of Indiana was conducted. Of the 46 respondents, most provide direct patient care (69.6 %), have worked in their current position for 5 years or less (72.1 %), and are experienced genetic counselors, having graduated between 6 and 15 years ago (43.5 %). One-third (32.6 %) reported thinking about leaving their current position at least monthly. GCs were more likely to think about leaving their current position when they provided direct patient care (p = 0.04) and worked in a hospital/clinic setting (p = 0.01). Among the 18 respondents that changed jobs in the past two years, 55.6 % currently work in a laboratory/industry setting and 44.4 % provide direct patient care, compared to 8 % of those in a stable position (N = 25) who work in a laboratory/industry setting (p < 0.01) and 88 % who provide direct patient care (p < 0.01). Genetic counselors who have changed jobs within the past 2 years were more satisfied with the possibility for advancement (p = 0.01), the recognition for work they do (p = 0.03) and feeling value from the organization (p = 0.04) in their current positions than those who have not changed jobs. Salary and flexibility were most often reported as reasons for changing jobs. This is the first documentation of the movement of GCs out of clinical roles into industry positions. This changing landscape may impact the access to clinical services and the training of genetic counseling students. This data will provide employers with data to help attract and retain GCs in clinical roles.  相似文献

Thought records are one of the most effective CBT interventions. However, clients can find them overly intellectual. While clients may logically understand that their balanced thought is accurate, they may not be emotionally convinced, thus reducing the thought record’s effectiveness. In the present paper we describe how imagery can be used throughout the thought record process to enhance clients’ emotional engagement. We describe how imagery can be used to identify negative automatic thoughts, to increase the believability of evidence against negative automatic thoughts, and to increase emotional engagement with balanced thoughts.  相似文献

High levels of locus coeruleus (LC) tonic activity are associated with distraction and poor performance within a task. Adaptive gain theory (AGT; Aston-Jones & Cohen, 2005) suggests that this may reflect an adaptive function of the LC, encouraging search for more remunerative opportunities in times of low utility. Here, we examine whether stimulating LC tonic activity using designer receptors (DREADDs) promotes searching for better opportunities in a patch-foraging task as the value of a patch diminishes. The task required rats to decide repeatedly whether to exploit an immediate but depleting reward within a patch or to incur the cost of a time delay to travel to a new, fuller patch. Similar to behavior associated with high LC tonic activity in other tasks, we found that stimulating LC tonic activity impaired task performance, resulting in reduced task participation and increased response times and omission rates. However, this was accompanied by a more specific, predicted effect: a significant tendency to leave patches earlier, which was best explained by an increase in decision noise rather than a systematic bias to leave earlier (i.e., at higher values). This effect is consistent with the hypothesis that high LC tonic activity favors disengagement from current behavior, and the pursuit of alternatives, by augmenting processing noise. These results provide direct causal evidence for the relationship between LC tonic activity and flexible task switching proposed by AGT.  相似文献

The purpose of the research is to investigate the mediating role of resiliency in the relation between temperamental traits and posttraumatic growth. Data of 74 persons who have experienced the death of someone close were analyzed. The range of age of the participants was 21–74 years (M = 38.4; SD = 15.5). The Posttraumatic Growth Inventory (PTGI), the Formal Characteristics of Behavior–Temperament Inventory (FCB-TI), and the Resiliency Assessment Scale were used in the study. Resiliency plays a mediating role among four traits of temperament (Briskness, Emotional Reactivity, Endurance, and Activity) and posttraumatic growth. Resiliency seems to modify the direct impact of temperamental traits on positive posttraumatic changes.  相似文献
