Lexical and semantic representations in the acquisition of L2 cognate and non-cognate words: evidence from two learning methods in children

How bilinguals represent words in two languages and which mechanisms are responsible for second language acquisition are important questions in the bilingual and vocabulary acquisition literature. This study aims to analyse the effect of two learning methods (picture- vs. word-based method) and two types of words (cognates and non-cognates) in early stages of children's L2 acquisition. Forty-eight native speakers of European Portuguese, all sixth graders (mean age = 10.87 years; SD= 0.85), participated in the study. None of them had prior knowledge of Basque (the L2 in this study). After a learning phase in which L2 words were learned either by a picture- or a word-based method, children were tested in a backward-word translation recognition task at two times (immediately vs. one week later). Results showed that the participants made more errors when rejecting semantically related than semantically unrelated words as correct translations (semantic interference effect). The magnitude of this effect was higher in the delayed test condition regardless of the learning method. Moreover, the overall performance of participants from the word-based method was better than the performance of participants from the picture-word method. Results were discussed concerning the most significant bilingual lexical processing models.     

Antecedentes y aparición de la Psicología del Procesamiento de Información: un estudio histórico

Resumen

El presente artículo recopila los grandes hitos asociados al surgimiento de la Psicología del Procesamiento de Información (principales autores, obras, instituciones, eventos científicos, etc.) en Gran Bretaña y Estados Unidos, países en donde este enfoque tiene su origen. Esto se hace a través de una perspectiva de análisis histórico que, remontándonos a los años veinte—y tras pasar revista a los acontecimientos más relevantes para la Historia de la Psicología acaecidos durante los años treinta, cuarenta y cincuenta—, nos conduce a 1958, fecha clave para el nacimiento y difusión de lo que hoy conocemos como Psicología del Procesamiento de Información.     

Why do superiors attend to negative stereotypic information about their subordinates? Effects of power legitimacy on social perception

Power can be defined as control over other people's outcomes. Using this definition, we explored the impact of power on attentional processes involved in impression formation. Because powerful individuals may want to maintain and justify their position, powerful participants should pay particular attention to negative stereotype‐consistent information about their subordinates. In contrast, powerless participants should devote their attention to stereotype‐inconsistent information in an attempt to increase their control over the social context. Study 1 directly manipulated control by assigning participants to the role of leader or subordinate in a task group. Results showed that, compared to subordinates, leaders devoted more attention to negative stereotypic attributes. Study 2 manipulated the legitimacy of power and replicated the pattern found in Study 1 but only when power was illegitimate. Our findings suggest that the experience of power can be associated with feelings of threat, especially when power is illegitimate, thereby orienting impression‐formation processes toward information likely to maintain the existing social structure. We discuss our results in the context of current work on motivated social cognition, social identity, and legitimisation. Copyright © 2000 John Wiley & Sons, Ltd.     

Economic inequality enhances inferences that the normative climate is individualistic and competitive

In addition to the negative effects of economic inequality on a range of health and social outcomes, we propose that inequality should also affect how people perceive the broader normative climate in society. We predicted that people living in a more unequal (vs. equal) society are more likely to appraise the social context as one where individualism determines people's behavior. We tested this idea in three experiments by manipulating the degree of economic inequality in a fictional society. We showed that, compared to the low-inequality condition, participants in the high-inequality condition were more likely to project individualistic norms onto society. Furthermore, Experiments 2 and 3 showed that in the high- (vs. low-) economic-inequality condition, participants inferred more competition and less cooperation between people. Our results are discussed in light of the importance of the perception of a broader normative climate to explain the consequences of economic inequality.     

Towards a Comprehensive Understanding of Body Image: Integrating Positive Body Image,Embodiment and Self-Compassion

Body image (BI) disturbance is a relevant factor in the etiology and treatment of eating disorders (ED). Although progress has been made in recent decades in understanding BI and its relationship with ED, the efficacy of BI disturbance prevention and intervention programs is still limited. In order to reach deeper understanding of BI disturbance and clarify the interactions between some protective and risk factors related to this construct, we carried out a literature review on some specific BI-related factors that so far have been analyzed independently. We specifically examined positive and negative BI; embodiment and its role in the development of positive and negative BI; and self-compassion as a protective factor that promotes positive embodiment (vs. disembodiment) and protection against body shame. We conclude that integrating the available evidence on these factors into BI models may be used to enhance our understanding of BI and improve the efficacy of prevention and intervention programs to help fight negative BI (by reducing body shame and disembodiment) and promote positive BI (by increasing self-compassion and positive embodiment).     

Credentialing and certification in ethics consultation: lessons from palliative care

In response to an article by Acres and colleagues, "Credentialing the Clinical Ethics Consultant: An Academic Medical Center Affirms Professionalism and Practice:" the authors urge continued action for the credentialing and certification of clinical ethics consultants. They also promote a vigorous and engaged model for ethics consultation.     

Opioid mechanisms are involved in the disruption of arcaine-induced amnesia by context pre-exposure

Previous exposure to the training context disrupts glutamatergic N-methyl-d-aspartate receptor (NMDAr) antagonist-induced amnesia, indicating that novelty is necessary for such an amnestic effect. While there are reports that novelty-related release of opioids cause amnesia, no study has addressed whether the amnestic effect of NMDAr antagonists involve opioid mechanisms. In this study we investigated whether pharmacological manipulation of the opioid system immediately after context pre-exposure alters the amnestic effect of arcaine, a NMDAr antagonist. Adult male Wistar rats were habituated (pre-exposed) to a fear conditioning training apparatus or to a different context (open field). Immediately after pre-exposure, animals were injected with saline or naloxone (0.5 mg/kg, i.p.) or anti-beta-endorphin antibody (1:500, i.c.v.). Forty eight hours after pre-exposure session, all animals were subjected to fear conditioning acquisition protocol and saline or arcaine (30 mg/kg, i.p.) was administered immediately after training. Testing was carried out 24 h later, and freezing responses due to re-exposure to the training apparatus were recorded. Pre-exposure to the training apparatus prevented the impairment of memory induced by post-training arcaine. Administration of naloxone or anti-beta-endorphin antibody, immediately after pre-exposure to the training apparatus, reinstated the amnesic effect of post-training arcaine. The results suggest that endogenous opioid mechanisms are involved in the pre-exposure-induced loss of the amnestic effect of arcaine.     

A Case Study of Witness Consistency and Memory Recovery Across Multiple Investigative Interviews

Access to audio recordings of five interviews (Interviews 2–6), and to the interviewer's contemporaneous notes during an initial unrecorded interview, made it possible to assess consistency across repeated attempts by a 9‐year‐old to describe her older sister's abduction from their shared bedroom. Information provided in each of the interviews was systematically analysed to determine whether each unit of information was new, consistent (repeated) or contradictory in relation to earlier reported information and whether any informative detail provided in the witness' initial interview was subsequently omitted. In addition, the witness' accounts were compared with details provided by the victim upon her rescue. This case analysis is particularly informative in light of widespread professional concerns about the effects of repeated interviewing on the quality and accuracy of children's accounts of experienced events.

Permission to be prejudiced: Legitimacy credits in the evaluation of advertisements

We investigated discrimination in the context of evaluating advertisements, based on the suppression model (justification‐suppression model [JSM]) of prejudice expression. Previous research has demonstrated that when people are given an opportunity to give a high rating to an ad featuring a Black model, a sense of nonprejudice is created, which, in turn, provides an opportunity to discriminate subsequently without feeling prejudiced. We extended the JSM by investigating whether the acquisition of legitimacy credits (a moral authority earned by demonstrating nonprejudice) is a sufficient condition to release the expression of prejudice. We found that subjects who first evaluated a high‐quality ad featuring a Black model felt eligible to use legitimacy credits in subsequent evaluations. But in a subsequent study, participants who acquired these credits evaluated Black model ads more negatively than White model ads only when these ads were of low quality. The implications for evaluating the subtle way that prejudice affects rating of models of color in advertisements are discussed.
