The majority of studies investigating the effects of parental behaviour on the child’s adjustment have a dimensional approach. We identified the existence of various patterns in parental rearing styles and analysed the relationship between different parenting patterns and behavioural problems in a group of school-aged children. A longitudinal, multi-informant study was conducted. The sample consisted of 519 school-aged children from the Portuguese general population. Parental rearing styles were measured using the EMBU-C, a questionnaire that evaluates children’s perception of parental rearing dimensions. The assessment of child behavioural problems included the evaluation of internalizing and externalizing problems, and data from multiple reporters (parents and teacher). One year later, after a school transition, the adjustment of a sub-sample of 220 children was evaluated again. Cluster analysis identified four types of parental rearing styles: low support, supportive-controller, rejecting-controller, and supportive. In both assessment periods, low support and rejecting-controller parenting patterns showed higher levels of behavioural problems than the supportive and supportive-controller parenting patterns. These patterns show significant differences between them regarding behavioural problems and have a higher predictive value regarding externalizing problems (versus internalizing problems).  相似文献

Age of acquisition (AoA) is an important psycholinguistic variable that affects the speed and accuracy of lexical processing in tasks such as word naming, picture naming, and lexical decision. In the present work, we collected AoA ratings for 1,749 Portuguese words (nouns, verbs, adjectives, and adverbs), using a 9-point scale that was first proposed by Carroll and White (1973). We analyzed the relation between AoA ratings and other psycholinguistic variables (length measures, neighborhood density, written-word frequency, familiarity, imageability, and concreteness), and we assessed reliability by correlating our ratings with those from other databases presented for Portuguese, English, Spanish, and Italian. The full database can be downloaded from http://brm.psychonomic-journals.org/content/supplemental.  相似文献

Ethics has emerged as one of the most critical issues facing organizations. Given its importance, an extensive literature has evolved to understand the causes and consequences of (un)ethical decision making and behaviors in organizations. To date, much of this research has relied on research methods (e.g., experiments) that emphasize internal validity and control over external validity and generalizability. Although very informative, such studies frequently utilize samples that are not representative of working adults and their designs often fail to capture the contextual complexity that defines the day-to-day realities of organizational life. In this light, this special issue of Personnel Psychology encouraged scholars to investigate ethics within organizations and to offer rich theoretical explanations for why ethical failures and successes occur. The articles in this special issue address this important research agenda and make significant contributions to our understanding of ethics in organizations. Our introduction synthesizes these works, provides an overview of issues facing the broader behavioral ethics literature, and discusses areas for future research.  相似文献

Variants of adaptive Bayesian procedures for estimating the 5% point on a psychometric function were studied by simulation. Bias and standard error were the criteria to evaluate performance. The results indicated a superiority of (a) uniform priors, (b) model likelihood functions that are odd symmetric about threshold and that have parameter values larger than their counterparts in the psychometric function, (c) stimulus placement at the prior mean, and (d) estimates defined as the posterior mean. Unbiasedness arises in only 10 trials, and 20 trials ensure constant standard errors. The standard error of the estimates equals 0.617 times the inverse of the square root of the number of trials. Other variants yielded bias and larger standard errors.  相似文献

This paper reports a case study of acquired surface alexia in Spanish and discusses the most suitable tests to detect this syndrome in a writing system that is very regular for reading at the segmental and supra-segmental levels. Patient MM has surface alexia characterized by quantitatively good performance in reading words and pseudowords; accurate but slow and syllabic reading of words, nonwords and sentences; good performance in lexical decision tasks including words and nonwords; errors in lexical decision with pseudohomophones; and homophone confusions. This pattern of reading can be interpreted as a disorder in the lexical reading route and overdependence on the non-lexical route. We discuss nonlexical impairments and the interpretation of alexia and suggest tasks to identify surface alexia in a shallow orthography.  相似文献

In the experiments described in this article we investigated the control of stiffness of the effector system in relation to parameters of the movement. If the velocity of a movement is chosen, it appears that at the same time the stiffness of the effector system is set to a preferred value. By changing the instruction given to the subject it is possible to change the relationship between velocity and stiffness without changing the kinematic parameters of the movement.Finally, the changes of stiffness and velocity in a learning process are studied. In conformity with what might be expected on intuitive grounds, it is found that velocity increases spontaneously during learning while stiffness decreases. The results are discussed in connection with the generation of motor programmes.  相似文献

Abstract

Studying the works of Freud and Lacan, the authors carried out research on perversion in childhood. Their work covered the perverse polymorphism of infantile sexuality and the perception of the anatomic difference between the sexes that leads the child to create sexual theories and fantasies. The phallic mother and the fetish are viewed as imaginary solutions directly related to the Oedipus and castration complexes. In perversion, a particular position is taken in relation to the Oedipus complex: a serious flaw occurs in the symbolization of the law, and the mechanisms of denial and disavowal take form. Sexuality requires a second “logical time,” separated from infancy by the latency period, in order to confirm (in action) that a fixed position of jouissance (enjoyment) has actually been established. This can only happen in a period after adolescent enhancement. The distinction between perverse traces and a perverse structure is made, taking into account the fact that, in the case of child analysis, the analyst should free the child from the family fantasy and help him/her to build his/her own fantasy.

Campos Santoro V. et al. Perversion und Kindheit und Adoleszenz.

Im Studium der Arbeiten von Freud und Lacan haben die Autoren Forschung über Perversion in der Kindheit gemacht. Die Studien behandeln den perversen Polymorphismus der infantilen Sexualität und die Wahrnehmung des anatomischen Unterschiedes zwischen den Geschlechtern, welche das Kind dazu führt, Sexual-Theorien und Phatasien zu schaffen.

Die phallische Mutter und der Fetisch werden als imaginäre Lösungen angesehen, die sich direkt auf den Ödipus- und Kastrations-Komplex beziehen. Bei der Perversion wird eine besondere Position in Bezug auf den Ödipus angenommen; ein ernsthafter Mangel tritt bei der Symbolisierung des Rechts auf; die Mechanismen der Verneinung und der Verleugnung bilden sich. Sexualität erfordert eine zweite “logische Zeit”, von der Kindheit durch die Latenz Periode getrennt, um (in der Handlung) zu bestätigen, daß eine fixierte Position der jouissance (Vergnügung) sich tatsächlich etabliert hat. Das kann sich nur in einer Periode nach der adoleszenten Verstärkung ereignen.

Es wird die Unterscheidung zwischen perversen Spuren und einer perversen Struktur gemacht, in Rechnung stellend, daß im Fall der Kinder-Analyse der Analytiker das Kind von der Familien-Phantasie befreien sollte und ihm/ihr helfen sollte, seine/ihre Phantasie auszubilden.

Campos Santoro V. Perversión e infancia y adolescencia.

Estudiando los trabajos de Freud y Lacan, los autores han investigado la perversión en la niñez. Los estudios cubren la sexualidad infantil perversa polimorfa y la percepción de la diferencia anatómica entre los sexos, que llevan al niño a crear teorías sexuales y fantasías.

La madre fálica y el fetiche son vistos como soluciones imaginarias relacionadas directamente con el complejo de Edipo y de castración. La perversión, toma una posición particular en relación al Edipo; un fallo importante tiene lugar en la simbolización de la ley; los mecanismos de negación y repudio toman forma. La sexualidad requiere un segundo “tiempo lógico” separado de la infancia por el periodo de latencia, para confirmar (en acto) que una posición fija de jouissance (goce) se ha establecido. Esto solo puede ocurrir en un periodo posterior a la intensificación adolescente.

La distinción entre las huellas perversas y la estructura perversa se ha hecho, teniendo en cuenta que, en el caso del análisis de niños, el analista debe librar al niño de la fantasía familiar y ayudar a el/ella a construir su propia fantasía.  相似文献

Self-determination was examined as a protective factor against the detrimental impact of negative life events on suicide ideation in adolescents. It is postulated that for highly self-determined adolescents, negative life events have a weaker impact on both hopelessness and suicide ideation than for non-self-determined adolescents. In turn, hopelessness is hypothesized to generate less suicide ideation for highly self-determined individuals. Results from multigroup analyses confirm that both the direct and indirect links between negative life events and suicide ideation were significantly weaker among participants high in self-determination. The protective role of self-determination against negative life events is discussed.  相似文献

Excitation of the mesocorticolimbic pathway, originating from dopaminergic neurons in the ventral tegmental area (VTA), may be important for the development of exaggerated fear responding. Among the forebrain regions innervated by this pathway, the amygdala is an essential component of the neural circuitry of conditioned fear. The functional role of the dopaminergic pathway connecting the VTA to the basolateral amygdala (BLA) in fear and anxiety has received little attention. In vivo microdialysis was performed to measure dopamine levels in the BLA of Wistar rats that received the dopamine D(2) agonist quinpirole (1 μg/0.2 μl) into the VTA and were subjected to a fear conditioning test using a light as the conditioned stimulus (CS). The effects of intra-BLA injections of the D(1) antagonist SCH 23390 (1 and 2 μg/0.2 μl) and D(2) antagonist sulpiride (1 and 2 μg/0.2 μl) on fear-potentiated startle (FPS) to a light-CS were also assessed. Locomotor performance was evaluated by use of open-field and rotarod tests. Freezing and increased dopamine levels in the BLA in response to the CS were both inhibited by intra-VTA quinpirole. Whereas intra-BLA SCH 23390 did not affect FPS, intra-BLA sulpiride (2 μg) inhibited FPS. Sulpiride's ability to decrease FPS cannot be attributed to nonspecific effects because this drug did not affect motor performance. These findings indicate that the dopamine D(2) receptor pathway connecting the ventral tegmental area and the basolateral amygdala modulates fear and anxiety and may be a novel pharmacological target for the treatment of anxiety.  相似文献
