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.     

Cultural innovation and transmission of tool use in wild chimpanzees: evidence from field experiments

Chimpanzees (Pan troglodytes) are the most proficient and versatile users of tools in the wild. How such skills become integrated into the behavioural repertoire of wild chimpanzee communities is investigated here by drawing together evidence from three complementary approaches in a group of oil-palm nut- (Elaeis guineensis) cracking chimpanzees at Bossou, Guinea. First, extensive surveys of communities adjacent to Bossou have shown that population-specific details of tool use, such as the selection of species of nuts as targets for cracking, cannot be explained purely on the basis of ecological differences. Second, a 16-year longitudinal record tracing the development of nut-cracking in individual chimpanzees has highlighted the importance of a critical period for learning (3–5 years of age), while the similar learning contexts experienced by siblings have been found to result in near-perfect (13 out of 14 dyads) inter-sibling correspondence in laterality. Third, novel data from field experiments involving the introduction of unfamiliar species of nuts to the Bossou group illuminates key aspects of both cultural innovation and transmission. We show that responses of individuals toward the novel items differ markedly with age, with juveniles being the most likely to explore. Furthermore, subjects are highly specific in their selection of conspecifics as models for observation, attending to the nut-cracking activities of individuals in the same age group or older, but not younger than themselves. Together with the phenomenon of inter-community migration, these results demonstrate a mechanism for the emergence of culture in wild chimpanzees.     

The use of tokens as rewards and tools by chimpanzees (Pan troglodytes)

This paper explores the effectiveness of token rewards in maintaining chimpanzees (Pan troglodytes) in working at intellectually costly tasks, and studies the "saving" behavior of the subjects, investigating the factors that can condition it. Two experiments were run. Tokens were introduced as rewards in a matching-to-sample task and used as exchange tools for food by three adult female chimpanzees. Subjects' performances were maintained at constant high levels of accuracy, suggesting that the tokens were almost equivalent to direct food rewards. The results also showed the emergence of saving behavior. The subjects spontaneously saved the tokens during the matching-to-sample task before exchanging them for food. The chimpanzees also learned a new symbolic discrimination task, with tokens as the reward. During this learning process a rarely reported phenomenon emerged: one of the subjects showed symmetry, a form of stimulus equivalence.

The Need to Present a Perfect Body Image: Development of a New Measure of Perfectionistic Self-Presentation

Perfectionistic self-presentation is linked to different clinical conditions and specially to eating disorders. In fact, the role that the drive to reach “perfection” and display it to others plays on eating and body image-related symptoms has long been the target of theoretical and empirical interest. However, an instrument that specifically assessed the need to present a perfect body image to others did not exist. The current study presents the development and validation of the Perfectionistic Self-Presentation Scale – Body Image (PSPS-BI), a measure designed to assess the need to present a perfect body image to others by displaying a flawless physical appearance and by occulting perceived imperfections in a public context. Three studies that included a total of 364 males and 541 females with ages between 18 to 38 years, were used to examine the structure and psychometric properties of the scale. Results showed that PSPS-BI presents two factors that measure the concealment of body imperfections and the display of body perfection. PSPS-BI revealed good internal reliability and temporal stability. Also, the PSPS-BI revealed good concurrent validity, tested with measures of perfectionism, body image flexibility, and general and eating psychopathology. Furthermore, a mediational analysis indicated that the need to present a perfect body image to others fully mediates the relationship between a general measure of perfectionistic self-presentation and drive for thinness, in both men and women. PSPS-BI showed good preliminary evidence as a reliable and accurate measure that seems to offer new possibilities to the research field of body image and eating-related difficulties.     

How do children deal with socio-moral conflicts? Self-conscious emotions and conflict resolution in the narratives of institutionalized and noninstitutionalized children

Introduction

Self-conscious emotions play an important role in children's psychosocial functioning.

The practices of existential psychotherapists: development and application of an observational grid

Within the major therapeutic paradigms, observational instruments have been developed to assess orientation-specific interventions or processes. However, to date, no such instrument exists to assess existential practices. Recent research indicates the key practices of existential therapists, and forms an empirical basis on which to develop an observatory grid. This paper describes the development of such a grid, and its exploratory testing with eight clients of four Portuguese existential psychotherapists. A total of 32 sessions were observed and both speaking turn and whole-session analysis showed that it was feasible to assess existential therapy using the instrument, although psychometric findings recommend further refinement of the tool. Session-rating data suggest that the chief practices applied by existential therapists were relational, followed by the use of hermeneutic interventions and reformulations. Interventions based on phenomenological and existential assumptions were observable in practice but limited in frequency. Further refinements and developments of the observational grid, together with additional research – using a range of therapists from different schools of existential therapy – are recommended.     

Self-reported psychosocial factors among in vitro fertilization patients interviewed alone or with the partner

The purpose of this study was to compare the sociodemographic and psychosocial characteristics reported by female in vitro fertilization (IVF) patients interviewed alone or with the partner in heterosexual couples. During 12 months (2011–2012), all patients undergoing IVF or intracytoplasmic sperm injection at one public reproductive medicine unit, in Portugal, were interviewed on the day of the diagnosis of pregnancy, being recruited 221 women interviewed with the partner and 92 interviewed alone. Interviewers collected data on sociodemographic and obstetric characteristics; and anxiety, depression, social support and partner relationship were collected by self-administered questionnaires. χ² test was used to assess the independent association between the categorical variables and being interviewed alone or with the partner. For continuous variables, mean or median differences were compared by the t-test or the Mann–Whitney test, according to data distribution. No statistically significant differences were found in the self-reporting of depression, anxiety, social support and partner relationship or in sociodemographic and obstetric characteristics between women interviewed alone or with the partner. Although women interviewed alone were older and more frequently had children than women interviewed with the partner, no significant associations were observed. Thus, having a male partner present in the research setting during a self-administered questionnaire seems not to influence women’s responses to psychosocial measures. Other outcomes and settings need to be evaluated to support evidence-based guidelines for research on infertility.     

Depression and anxiety symptoms following cancer diagnosis: a cross-sectional study

Introduction: The aims of the present study were to assess demographic and clinical characteristics of patients after receiving a cancer diagnosis, and to determine possible risk factors for anxiety and depression. Methods: All consecutive patients aged 18 or above, were assessed before starting intravenous chemotherapy for the first time with the Hospital Anxiety and Depression Scale (HADS), the Distress Thermometer, and a Visual Analog Scale for pain. Demographic and clinical data were also collected. Results: The patients assessed (n = 270) had a mean age of 59.4 (SD = 11.8) years, and 50.7% were women. Tumours were more frequently colorectal (27.2%), lung (18.8%) and breast (17.6%), and 68.9% were stages 3 or 4. A HADS Anxiety score ≥8 was present in 30% of the patients, a Depression score ≥8 in 24.1%, and a Distress score ≥4 in 44.4%. Independent risk factors for HADS Depression score ≥8 were being a woman (OR = 2.45; p = 0.004), being older (OR = 1.04; p = 0.005), and cancer stage 3–4 (OR = 2.24; p = 0.023) in the multivariable analysis; for Anxiety ≥8 they were being a woman (OR = 2.47; p = 0.002), having a past psychiatric consultation (OR = 2.83; p = 0.029), and cancer stage 3–4 (OR = 1.90; p = 0.047). Conclusion: These results suggest the need for greater awareness and a differentiated approach to patients at increased risk of anxiety and depression in the early stages of treatment and before starting chemotherapy.     

Longitudinal Study of Life Events,Well-Being,Emotional Regulation and Depressive Symptomatology

Etiological research regarding adolescent depression is relatively recent and longitudinal studies are needed to explicate the mechanisms by which risk and protective factors impact the development of depression. This investigation evaluated the effects of time 1 predictors (e.g., depressive symptoms, life events, subjective well-being, and emotion regulation strategies) on depressive symptoms assessed at time 2 (1 year later). The sample comprised 182 Portuguese adolescents, aged 12–16. Time 1 depressive symptoms and psychological well-being were significant predictors of time 2 depressive symptoms. Time 1 rumination predicted time 2 depressive symptoms, but time 2 brooding mediated this effect. Time 1 life events did not predict time 2 depressive symptomatology. This study identified several factors that seem to play an important role in the development of depressive symptomatology. Previous depressive symptomatology and well-being had a significant effect in this process and the relationship between rumination in time 1 and depressive symptoms at time 2 (1 year later) was fully mediated by brooding at time 2. Given these results, implications for prevention and treatment of depression include addressing risk factors like early depressive symptoms, rumination and brooding, and increasing the protective effect of psychological well-being.     

Personality Traits and Plagiarism: an Empirical Study with Portuguese Undergraduate Students

Academic dishonesty is a major problem and is thus a highly relevant area of inquiry. Considerable research has shown that key traits from the Big Five model of personality are associated with various forms of anti-social behaviour. To date, however, relatively little research interest has been devoted to study the relationship between personality traits and plagiarism. This study attempts to fill this gap by examining the relationship between the Big Five personality traits and the inclination to commit plagiarism by undergraduate students. The main conclusion is that the inclination to plagiarize is negatively associated with Conscientiousness and Agreeableness traits. Neuroticism was not found to be related to the inclination to plagiarize. Implications of the findings are discussed.
