Attachment Patterns as Mediators of the Link Between Combat Exposure and Posttraumatic Symptoms: A Study Among Portuguese War Veterans

We analyzed the role of both attachment anxiety and attachment avoidance as a mediators of the effects of combat exposure on posttraumatic stress disorder (PTSD) symptoms. Participants were Portuguese veterans (N = 60) divided into 2 groups: 30 suffered from chronic PTSD (nonrecovered) and 30 had remission from PTSD (recovered). Combat exposure, attachment patterns, and PTSD symptoms were assessed through self-report measures. Mediation test was performed by conducting several hierarchical regression analyses. Results showed higher attachment anxiety among nonrecovered participants. We did not find statistically significant differences between groups for both attachment avoidance and combat exposure level scores. In mediation analysis, at first step, attachment avoidance was not a significant predictor of PTSD symptoms, and attachment avoidance did not enter in subsequent analysis. Attachment anxiety was a partial mediator of the effect of combat exposure on PTSD symptoms. Implications of the findings for both attachment theory and clinical intervention on trauma are discussed.     

When our thoughts are not our own: Investigating agency misattributions using the Mind-to-Mind paradigm

At the core of the sense of agency for self-produced action is the sense that I, and not some other agent, am producing and directing those actions. While there is an ever-expanding body of empirical research investigating the sense of agency for bodily action, there has, to date, been little empirical investigation of the sense of agency for thought. The present study uses the novel Mind-to-Mind paradigm, in which the agentive source of a target thought is ambiguous, to measure misattributions of agency. Seventy-two percent of participants made at least one misattribution of agency during a 5-min trial. Misattributions were significantly more frequent when the target thought was an arousing negative thought as compared to a neutral control. The findings establish a novel protocol for measuring the sense of agency for thought, and suggest that both contextual factors and emotional experience play a role in its generation.     

Schooling in western culture promotes context-free processing

Culture has been shown to influence the way people apprehend their physical environment. Cognitive orientation is more holistic in East Asian cultures, which emphasize relationships and connectedness among objects in the field, than in Western cultures, which are more prone to focus exclusively on the object and its attributes. We investigated whether, beyond, or in conjunction with culture, literacy and/or schooling may also have an influence on this cognitive orientation. Using the Framed-Line Test both in Portugal and in Thailand, we compared literate schooled adults with two groups of unschooled adults: one of illiterates and one of ex-illiterates. As in former studies on Western people, Portuguese-schooled literates were more accurate in the absolute task than in the relative task. In contrast, Portuguese illiterates and ex-illiterates were more accurate in the relative task than in the absolute task. Such an effect of schooling was not observed in the Thai groups, all of whom performed better on the relative task. Thus, the capacity to abstract from contextual information does not stem only from passive exposure to the culture or the physical environment of Western countries. Western schooling, as part of or in addition to culture, is a crucial factor.     

The developmental turnpoint of orthographic consistency effects in speech recognition

The influence of orthography on children's online auditory word recognition was studied from the end of Grade 4 to the end of Grade 9 by examining the orthographic consistency effect in auditory lexical decision. Fourth-graders showed evidence of a widespread influence of orthography in their spoken word recognition system; words with rimes that can be spelled in two different ways (inconsistent) produced longer auditory lexical decision times and more errors than did consistent words. A similar consistency effect was also observed on pseudowords. With adult listeners, on exactly the same material, we replicated the usual pattern of an orthographic consistency effect restricted to words in lexical decision. From Grade 6 onward, this adult pattern of orthographic effect on spoken recognition is already observable.     

Selective exposure to television programmes and advertising effectiveness

This study focused on the influence of selective exposure within an experiment designed to investigate context effects on advertising effectiveness. In a semi‐natural viewing environment, 86 participants chose one of four television programmes to view. The programmes belonged to diverse genres: news and current affairs, light entertainment, sport, and action‐adventure. Each programme was interrupted by two commercial breaks containing unfamiliar advertisements for familiar product types. Self‐rated involvement, entertainment, and enjoyment of programmes correlated positively with subsequent measures of memory for and responses to the advertisements. The results support the hypothesis that the operation of selective exposure within an experimental situation may result in positive relationships between predictor variables and measures of advertisement effectiveness.

Recent theoretical convergences in psychoanalysis and their epistemological importance

In this paper, the author starts by examining the recent occurrence of an increasing receptivity and critical exchange between different schools of psychoanalytical thought. Among its consequences have been convergences in the understanding of countertransference, especially through the hypotheses of projective identification and countertransferential enactment. The prevalence of these hypotheses points towards the fact that the community of analysts is bringing about an informal and convergent clinical research conducted by a wide and heterogeneous range of its members. The importance and epistemological relevance of this kind of 'informal clinical research' for the construction of psychoanalytical knowledge is emphasised. This process in psychoanalysis is compared with the evolution of knowledge in other scientific areas, highlighting their similarities and their differences. The author shows how Freud's 'mystic writing-pad'model can be expanded to represent the object of psychoanalytical investigation and to bring a better understanding of the reason why the hypotheses of projective identification and countertransferential enactment occupy such a central position in psychoanalysis. In addition, consideration is given to how this kind of research can help in the difficult task of finding criteria for the evaluation of different psychoanalytical concepts. Finally, the author demonstrates how, using this approach, some of the important divergences in contemporary psychoanalysis can be viewed from a new perspective.     

Assessing reading comprehension with narrative and expository texts: Dimensionality and relationship with fluency,vocabulary and memory

Reading comprehension assessment should rely on valid instruments that enable adequate conclusions to be taken regarding students' reading comprehension performance. In this article, two studies were conducted to collect validity evidence for the vertically scaled forms of two Tests of Reading Comprehension for Portuguese elementary school students in the second to fourth grades, one with narrative texts (TRC‐n) and another with expository ones (TRC‐e). Two samples of 950 and 990 students participated in Study 1, the study of the dimensionality of the TRC‐n and TRC‐e forms, respectively. Confirmatory factor analyses provided evidence of an acceptable fit for the one‐factor solution for all test forms. Study 2 included 218 students to collect criterion‐related validity. The scores obtained in each of the test forms were significantly correlated with the ones obtained in other reading comprehension measures and with the results obtained in oral reading fluency, vocabulary and working memory tests. Evidence suggests that the test forms are valid measures of reading comprehension.
