False action memories in older adults: Relationship with executive functions?

Merely observing another person performing an action can make young people later misremember having performed this action themselves (the observation-inflation effect). We examined this type of memory error in healthy older adults. Overall, both young and older adult groups showed robust observation inflation. Although the number of people committing observation-inflation errors did not differ between age groups, those older adults who were prone to this illusion showed a greater observation-inflation effect compared to the corresponding young. At the same time, observation also had beneficial effects on subsequent action memory, especially in older adults. Surprisingly, executive functioning was not correlated with the degree to which older adults made observation-inflation errors, but it was related to the degree to which older adults benefited from observation. We consider accounts of observation inflation based on source monitoring, familiarity misattribution, and motor simulation.     

Acculturation Preference Profiles of Spaniards and Romanian Immigrants: The Role of Prejudice and Public and Private Acculturation Areas

The main goal of this study was to identify acculturation preference profiles using cluster analysis in public and private areas of culture in the host and immigrant populations, and to find out the relationship between these profiles and prejudice levels. Four hundred and ninety-nine Spaniards and 500 Romanians participated in a survey. The sampling of Spaniards was multistage random and the sampling of Romanians was by quota. The results confirm our predictions. Romanians who are less prejudiced against Spaniards prefer assimilation in public areas and integration in private areas. Romanians who are more prejudiced against Spaniards prefer integration in public areas and separation in private areas. Spaniards who are less prejudiced against Romanians prefer integration in both public and private areas. Spaniards who are more prejudiced against Romanians prefer assimilation in both areas.     

Attention effects on auditory scene analysis: insights from event-related brain potentials

Sounds emitted by different sources arrive at our ears as a mixture that must be disentangled before meaningful information can be retrieved. It is still a matter of debate whether this decomposition happens automatically or requires the listener’s attention. These opposite positions partly stem from different methodological approaches to the problem. We propose an integrative approach that combines the logic of previous measurements targeting either auditory stream segregation (interpreting a mixture as coming from two separate sources) or integration (interpreting a mixture as originating from only one source). By means of combined behavioral and event-related potential (ERP) measures, our paradigm has the potential to measure stream segregation and integration at the same time, providing the opportunity to obtain positive evidence of either one. This reduces the reliance on zero findings (i.e., the occurrence of stream integration in a given condition can be demonstrated directly, rather than indirectly based on the absence of empirical evidence for stream segregation, and vice versa). With this two-way approach, we systematically manipulate attention devoted to the auditory stimuli (by varying their task relevance) and to their underlying structure (by delivering perceptual tasks that require segregated or integrated percepts). ERP results based on the mismatch negativity (MMN) show no evidence for a modulation of stream integration by attention, while stream segregation results were less clear due to overlapping attention-related components in the MMN latency range. We suggest future studies combining the proposed two-way approach with some improvements in the ERP measurement of sequential stream segregation.     

Forms and Functions of Aggression in Adolescents: Validation of the Portuguese Version of the Peer Conflict Scale

Aggression in adolescence may assume different forms and functions, and is often associated with maladjustment. To adequately assess aggression in adolescence, instruments need to evaluate both its forms and its functions, as is the case with the Peer Conflict Scale. This research presents and evaluates the Portuguese version of this instrument, and evaluates levels of aggression in an adolescent community sample (n?=?785; 63.6 % female, mean age of 15.97 years old). The four factor structure originally proposed for the instrument (i.e. proactive overt, reactive overt, proactive relational and reactive relational aggression) represented a satisfactory solution for the data, and for both girls and boys. Results also have shown adequate reliability. Regarding levels of aggression, boys reported being overall more aggressive than girls. When aggression is impulsive/ reactive, both boys and girls practice its overt form. It is only when the aggression is pondered upon (proactive) that boys and girls chose to use different forms of aggression. Accurately evaluating different forms and functions of aggression has implications for designing, implementing and evaluating adequate and tailored interventions.     

The role of working memory in inferential sentence comprehension

Existing literature on inference making is large and varied. Trabasso and Magliano (Discourse Process 21(3):255–287, 1996) proposed the existence of three types of inferences: explicative, associative and predictive. In addition, the authors suggested that these inferences were related to working memory (WM). In the present experiment, we investigated whether WM capacity plays a role in our ability to answer comprehension sentences that require text information based on these types of inferences. Participants with high and low WM span read two narratives with four paragraphs each. After each paragraph was read, they were presented with four true/false comprehension sentences. One required verbatim information and the other three implied explicative, associative and predictive inferential information. Results demonstrated that only the explicative and predictive comprehension sentences required WM: participants with high verbal WM were more accurate in giving explanations and also faster at making predictions relative to participants with low verbal WM span; in contrast, no WM differences were found in the associative comprehension sentences. These results are interpreted in terms of the causal nature underlying these types of inferences.     

Holistic processing of faces is intact in adults with autism spectrum disorder

Are face recognition difficulties in Autism Spectrum Disorders (ASD) related to impaired holistic processing? Gauthier et al. [Gauthier, I., Klaiman, C., &; Schultz, R. T. (2009). Face composite effects reveal abnormal face processing in Autism spectrum disorders. Vision Research, 49, 470–478. doi:10.1016/j.visres.2008.12.007] used the face composite task in adolescents with autism and found a congruency effect that was not modulated by alignment, a result which was interpreted as reflecting qualitatively different face processing mechanisms. In the present study we tested adults with ASD in a composite face task where presentation times were manipulated and further explored whether these participants were sensitive to holistic information in faces using a new version of the composite task: VHFPT 2.0 (The Vanderbilt Holistic Face Processing Test 2.0). Results suggest that adults with ASD process faces holistically and that their facial identity processing abilities are qualitatively similar and as efficient as that of typical adults. The difference between the results of Gauthier et al. (2009) with adolescents and the results with adults here reported are interpreted in terms of a developmental delay.     

Palliative sedation: clinical context and ethical questions

Practitioners of palliative medicine frequently encounter patients suffering distress caused by uncontrolled pain or other symptoms. To relieve such distress, palliative medicine clinicians often use measures that result in sedation of the patient. Often such sedation is experienced as a loss by patients and their family members, but sometimes such sedation is sought as the desired outcome. Peace is wanted. Comfort is needed. Sedation appears to bring both. Yet to be sedated is to be cut off existentially from human experience, to be made incapable of engaging self-consciously in any human action. To that extent, it seems that to lose consciousness is to lose something of real value. In this paper, I describe how sedation and the question of intentionally bringing about sedation arise in the care of patients with advanced illness, and I propose heuristics to guide physicians, including Christian physicians, who seek to relieve suffering without contradicting their profession to heal.     

Posttraumatic Growth in Children and Adolescents Exposed to the 2010 Earthquake in Chile and Its Relationship with Rumination and Posttraumatic Stress Symptoms

The aim of this study was to assess a predictive model of posttraumatic growth and posttraumatic stress symptoms in children and adolescents exposed to the earthquake in Chile in 2010. 325 children (47.4% male), aged between 10 and 15 years, were surveyed 12 months after the earthquake. The following tests were administered: the posttraumatic growth inventory for children in its brief version of Kilmer et al., the child PTSD symptom scale of Foa et al., the rumination scale for children of Crider et al., along with a scale to assess the trauma severity and a socio-demographic questionnaire. The model was assessed through a path analysis, which showed that deliberate rumination mediated the relationship between trauma severity and intrusive rumination with posttraumatic growth, that intrusive rumination mediated the relationship between the severity of the event and posttraumatic stress symptoms and that the latter mediated the relationship between intrusive rumination and posttraumatic growth. The sex was included as control variable in the path model. The final model achieved adequate fit indexes. The relevance of rumination processes for the development of the psychological consequences in children and adolescents following a natural disaster and their implications for clinical is discussed.     

Adoptive versus Mixed Families: Child Adjustment,Parenting Stress and Family Environment

Recent research in adoption has considered the factors and processes that underlie the adjustment of children and families. However, little research has been conducted on certain types of adoptive families, specifically on families with both adoptive and biological children often designated as mixed families. This subject is addressed by the present study which also analyzes the association between the type of adoptive family and children’s outcomes—prosocial and problem behavior—parenting stress and the relational family environment. It also examines whether children’s gender, age at adoption and the number of children in the home moderate these effects. 102 parents of adoptive children (ACF) 33 parents of both adoptive and biological children (ABCF) and 102 parents of biological children (BCF) participated in the study. Target-children were aged from 6 to 12 years. The Portuguese versions of the SDQ-P, PSI-SF and FES (Interpersonal Relationship dimension) were used. Results showed that the type of adoptive family—ACF and ABCF—significantly explained the variance of children’s behavioral problems and parenting stress. The child’s gender was shown to moderate the relationship between ACF parents and their perception of child’s prosocial behavior. The results give relevant clues as to the importance of distinct outcomes in adoptive families—ACF and ABCF—compared to families with only biological children and should, therefore, be a resource for professionals involved in the adopters’ suitability assessment and adoption intervention.     

Triarchic Model of Psychopathy: A Brief Measure Among Detained Female Youths

The present study examined the psychometric properties of a brief measure of the Triarchic model of psychopathy based on the Youth Psychopathic Traits Inventory (YPI-Tri-S) among a forensic sample of detained female youth offenders (M = 16.41 years; SD = 1.19 years) from Portugal. Results supported the expected three-factor structure and cross-gender measurement invariance. The YPI-Tri-S showed good psychometric properties in terms of factor structure, internal consistency, convergent validity, discriminant validity, and criterion-related validity. Findings suggest that the YPI-Tri-S is a valid and reliable measure of the Triarchic model of psychopathy, which can be used to assess female juvenile offenders.
