The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.  相似文献

Fifteen-month-old infants detected a violation when an actor performed an action that did not match her preceding vocal cue: The infants looked reliably longer when the actor expressed a humorous vocal cue followed by a sweet action or expressed a sweet vocal cue followed by a humorous action, than when the vocal cue was followed by a matching action. The infants failed to detect the mismatch when one person expressed the vocal cue and another performed the action. The results suggest that by 15 months of age, infants are capable of distinguishing between two types of vocal cues and actions along the positive emotional spectrum: humor and sweetness. Furthermore, they match humorous vocal cues to humorous actions and sweet vocal cues to sweet actions only when the cues and actions are made by the same person.  相似文献

A quasi-experimental design was employed to compare depression at intake and completion of a sample of primarily Latina women court-ordered to a batterer intervention program. Data were derived from the intake assessments of 112 women over 24 months. Overwhelmingly, women reported being abused by their current and former partners. Approximately 58% of the women in this sample were depressed at intake. When culturally competent, gender-appropriate treatment is given to court-ordered women, depression symptomatology may decrease to levels of normal functioning. Further research is needed to understand court-ordered women as well as how to meet their unique needs.  相似文献

MTV’s hit programs 16 and Pregnant and Teen Mom have been the subject of national debate since their inception. Supporters contend that the shows inhibit pregnancy-risk behavior. Critics contend that the shows glamorize adolescent motherhood and encourage pregnancy-risk behavior. The present study explored the possibility that the association between viewing 16 and Pregnant and Teen Mom and student females’ pregnancy-risk behavior depends on the extent to which females’ parents communicated with them about sex while they were growing up. Survey data were gathered from 313 female students. A disordinal interaction was found between father–daughter sexual communication, viewing frequency, and recent intercourse behavior. Frequent viewing was associated with an increased probability of having engaged in recent intercourse for females whose fathers did not communicate with them about sex while growing up. Conversely, frequent viewing was associated with a decreased probability of having engaged in recent intercourse for females whose fathers often communicated about sex with them while growing up. No interaction was found between mother–daughter sexual communication, viewing frequency, and recent intercourse behavior. These results suggest that fathers may play an especially important role in determining how sexual media socialize their daughters.  相似文献

Research on imitation in infancy has primarily focused on what and when infants imitate. More recently, however, the question why infants imitate has received renewed attention, partly motivated by the finding that infants sometimes selectively imitate the actions of others and sometimes faithfully imitate, or overimitate, the actions of others. The present study evaluates the hypothesis that this varying imitative behavior is related to infants' social traits. To do so, we assessed faithful and selective imitation longitudinally at 12 and 15 months, and extraversion at 15 months. At both ages, selective imitation was dependent on the causal structure of the act. From 12 to 15 months, selective imitation decreased while faithful imitation increased. Furthermore, infants high in extraversion were more faithful imitators than infants low in extraversion. These results demonstrate that the onset of faithful imitation is earlier than previously thought, but later than the onset of selective imitation. The observed relation between extraversion and faithful imitation supports the hypothesis that faithful imitation is driven by the social motivations of the infant. We call this relation the King Louie Effect: like the orangutan King Louie in The Jungle Book, infants imitate faithfully due to a growing interest in the interpersonal nature of interactions.

An important amount of literature about job insecurity and its consequences has been developed during the past few decades (Sverke, Hellgren, & Näswall, 2002 Sverke, M., Hellgren, J. and Näswall, K. 2002. No security: A meta-analysis and review of job insecurity and its consequences. Journal of Occupational Health Psychology, 7(3): 242264. [Crossref], [PubMed] [Google Scholar]). Most of this research has focused on an individual-analysis perspective, without taking into account social context. Although job insecurity climate has not been empirically examined, several authors have implicitly assumed that job insecurity contexts exist in some organizations where layoffs have occurred. Therefore, they examined layoff survivors' reactions. From this perspective, the aim of this study was to validate the job insecurity climate concept and examine its influence on employees' job attitudes. In order to provide additional support, this objective was examined in two samples: 428 employees belonging to 20 Spanish organizations and 550 employees in 18 Belgian organizations. The results showed that job insecurity climate emerged within the organizations in both samples, and that it influenced employees' job satisfaction and organizational commitment above and beyond individual perceptions of job insecurity in the Spanish sample. The implications and limitations of this study are discussed.  相似文献

The influence of religious education in the family upon current spiritual and religious tendencies was assessed in a sample of 599 Spanish nurse and medicine students using a religiosity scale and answers to a series of belief/disbelief statements. Results showed that nursing and medicine students were equally low-religious, with no differences in religiosity total scores between participants coming from religious families; however, medical students coming from nonreligious families showed higher religiousness than the corresponding nursing trainees. This distinction appeared both across religiosity items and in a variety of responses to belief/disbelief of Christian/secular assertions. Regression analysis showed that religious family background was a consistent predictor of religious beliefs at young adulthood, and its influence was higher for medical students. In addition to establish religious upbringing as an important factor modulating enduring religiosity, these findings provide distinctions between nurse and medical trainees, and reproduce, in a Spanish mainly catholic sample, the structure of religiosity factors previously found on North American mainline protestants.  相似文献

In this article, we identify ten reasons why discrepancy scores (based on differences between IQ and reading achievement scores) provide an inadequate means for identifying children with reading disabilities. We recommend instead that children be identified simply on the basis of problems in reading skills, regardless of their IQs.  相似文献

Narrative approaches to teaching multicultural counseling can assist students in integrating course content with a sense of self. Narrative teaching strategies follow a postmodern view of learning—that is, that truth is constructed through the interaction of participants. Justification for narrative approaches to teaching multicultural counseling and narrative are introduced. Los enfoques narrativos para enseñar la consejería multicultural pueden ayudar a los estudiantes a integrar el contenido del curso con su sentido de ser. Las estrategias de la enseñanza narrativa siguen un panorama postmoderno de aprendizaje—que considera que la verdad se construye por la interacción de participantes. La justificación para enfoques narrativos para enseñar la consejería multicultural y la narrativa se introducen.  相似文献

Guided by both attachment and social support theories, the authors conducted a longitudinal investigation exploring the concomitant effects of perceptions of spouse support (anticipated and received spouse support) and internal working models of attachment (positive–self and positive–other), on childbearing depressive symptomatology. Distinct main and interaction effects for attachment dimensions and perceived support variables were hypothesized for high– and low–risk pregnancies. Participants in the final sample were 200 pregnant women who completed the self–report between the 25th and the 29th weeks of pregnancy, and 8 weeks after childbirth. Controlling for initial levels of depressive symptoms and health conditions, results demonstrated the protective role of high levels of received support and of positive–other models on childbirth depressive symptoms. Moreover, received support and models of positive–other were found to interact with health conditions, producing distinct moderation effects: Received support was found to be a significantly stronger protective factor for childbearing depression among women with low–risk pregnancies; positive–other models were found to be a significantly stronger protective factor among women with high–risk pregnancies. The implications of these findings for the understanding of intrapersonal and interpersonal factors in successful coping with a health risk situation are discussed.  相似文献
