Until recently historians and sociologists tended to view juvenile delinquency within the context of subcultural theory. This was often supported by evidence taken from contemporary sources. A closer and more skillful reading of the evidence suggests that juveniles fluctuated between normative values and those of the sub‐culture of delinquency (as stated by Matza). Also they were seen by adults within a conflicting paradigm as objects of contempt on one hand and young innocents in need of care and protection on the other. 相似文献

In models of affect and cognition, it is held that positive affect broadens the scope of attention. Consistent with this claim, previous research has indeed suggested that positive affect is associated with impaired selective attention as evidenced by increased interference of spatially distant distractors. However, several recent findings cast doubt on the reliability of this observation. In the present study, we examined whether selective attention in a visual flanker task is influenced by positive mood induction. Across three experiments, positive affect consistently failed to exert any impact on selective attention. The implications of this null-finding for theoretical models of affect and cognition are discussed. 相似文献

Abstract It is widely known that Freud gives Oedipus a central place in both his psychoanalytic theory and praxis. Freud introduces the Oedipus myth as the crucial key for understanding the tragedy of human life. One of the most problematic issues innate to the human condition is aggression. This paper argues: (1) that Freud's insights into human aggression can at the very least be viewed as one-sided and problematic; and (2) that the heuristic potential of the Oedipus myth is, correspondingly, limited. It considers how the Hungarian psychiatrist and analyst, Lipót Szondi, tries to bridge this gap using the myth of Cain and Abel. The aim of this paper is to explore how Szondi's interpretation of this myth offers a much more subtle approach to human aggression. Szondi's alternative and distinctive look at aggressive phenomena offers an exciting and fruitful addition to Freud's interpretation as exclusively referring to sadism and/or the death instinct. This contribution wants to highlight Szondi's amendment to Freud's Oedipus and aims to show that psychoanalysis can benefit from taking into account the mythical figures of Cain and Abel. 相似文献

The present study examined if habit strength moderated the influence of intention on fruit consumption in a Dutch adult sample (N?=?521, 46.3% males, mean age?=?34.50, SD?=?10.87), using the theoretical relations of the Theory of Planned Behaviour (TPB). TPB variables and habit strength were assessed at baseline. Fruit consumption was assessed with a validated questionnaire five weeks later. Three groups were created: low habit strength (n?=?180), medium habit strength (n?=?185) and high habit strength (n?=?156). Confirmatory factor analyses and multi-group path analyses were performed using AMOS 4.0. A good fit was obtained for the overall measurement model and the structural models. Multi-group path analyses showed that intention was a significant predictor of fruit consumption in the low habit (β?=?0.36, p?<?0.001) and medium habit group (β?=?0.30, p?<?0.001), but a non-significant predictor in the high habit group (β?=?0.05, p?=?0.596). Implications for information-based and motivation-based interventions are discussed. 相似文献

It seems likely that proactive coping is an important mechanism for dealing successfully with threats to personal goals, yet little empirical research has been conducted in relation to this concept. The aim of the present study is to examine to what extent proactive coping is influenced by situation-specific features as well as by personal characteristics. Three vignettes, each representing a potential decline in an important resource (health, social relationships and finance), were presented to 123 adults between 50 and 70 years old. Multilevel analyses show that proactive coping is highly variable within persons and that three situational factors (type of stressor, appraised threat and appraised control) affected the employment of proactive coping strategies. Future temporal orientation was identified as a significant, positive predictor of proactive coping, but none of the other personal factors were found to be relevant. 相似文献

Abstract Self-efficacy expectations are important psychological determinants of smoking cessation. The present study aimed at exploring different sorts of self-efficacy. The following self-efficacy scales were composed: Emotional self-efficacy, Social self-efficacy, Skill self-efficacy, Relapse self-efficacy and Try self-efficacy. In a sample of 752 smokers with low motivation to quit, two subsequent self-report measurements of self-efficacy were conducted. Firstly, we investigated to what extent potential sources of self-efficacy - quitting history and smoking behavior -were related to the types of self-efficacy. The explained variance in self-efficacy scores ranged from 4.4% to 23.1%, and in all five types of self-efficacy, smoking behaviour explained a higher percentage of self-efficacy than quitting history. The number of past quit attempts was only related to Relapse self-efficacy. Secondly, we investigated to what extent the different types of self-efficacy at T1 were predictive of quitting behavior measured at T2. The results showed that only Skill self-efficacy was predictive of quitting activity between Tl and T2. Point prevalence quitting at T2 was predicted by Skill self-efficacy and Relapse self-efficacy. The latter type of self-efficacy, however, was a negative predictor of quitting. The different types of self-efficacy can be mapped on two dimensions: The extent to which the means to accomplish a certain task are specified in the questionnaire item; and the phase of behavior change to which the self-efficacy tasks are relevant. Based on the findings from the predictive validity, it is concluded that the more clearly the means to accomplish the task are specified, the more valid the self-efficacy judgements are. 相似文献

In this study, we examined the effect of multiple versus single stimulus presentation in typically developing readers and children with developmental dyslexia. The tasks involved either reading single words or arrays of words or naming single or multiple colors and digits (rapid automatized naming or RAN). To be able to compare these sets of conditions, we recorded total response times (i.e., the time between stimulus onset and the end of the participant’s vocal response) in all cases. The study included 43 typically developing readers and 25 children with dyslexia. Results indicate that typically developing readers have a clear advantage with multiple over single items on both RAN and reading tasks. The children with dyslexia showed a moderate advantage for multiple stimuli in naming colors and digits but presented the opposite pattern in reading.With regard to reading, the disproportionate impairment of the children with dyslexia in dealing with multiple arrays suggests difficulty in integrating the multiple subcomponents of the reading task over and above the basic nuclear deficit in decoding words. Regarding the RAN tasks, results confirm that the requirement of integrating multiple subcomponents may be critical in mediating the predictive value of these measures on reading. 相似文献

An analysis based on crystal symmetry and high-resolution transmission electron microscopy (HRTEM) is presented as a general methodology to identify planar defects on the basal planes of D019 compounds. As a starting point, the possible (close-packing preserving) planar defects are classified in accordance with their visibility, and the magnitude of the displacement vector on prismatic projections. Analysis of experimental HRTEM images, obtained under two different viewing conditions, followed by matching with simulated images, enables unambiguous identification to be made. The methodology is applied to planar defects observed in D019 Co3 相似文献

This article describes a design strategy deployed in developing ultra-ductile Mg alloys based on a microalloying concept, which aims to restrict grain growth considerably during alloy casting and forming. We discuss the efficiency of the design approach, and evaluate the resulting microstructural and mechanical properties. After processing, the so-designed alloys ZQCa3 (Mg–3Zn–0.5Ag–0.25Ca–0.15Mn, in wt.%) and ZKQCa3 (Mg–3Zn–0.5Zr–0.5Ag–0.25Ca–0.15Mn, in wt.%) reveal very fine grains (<10 µm), high ductility (elongation to fracture of up to 30%) at moderate strength or high strength (ultimate tensile strength of up to 350 MPa) at reasonable ductility. These properties are explained based on thermodynamic modelling, microstructure analysis including transmission electron microscopy studies, and microstructural and mechanical testing after annealing, and are compared to a related commercial alloy (ZK31). 相似文献
