Sublexical and Lexico-Syntactic Factors in Gender Access in Spanish

The influence of sublexical and lexico-syntactic factors during the grammatical gender assignment process in Spanish was studied in two experiments using the gender decision task. In Experiment 1, the regularity of the ending of gender-marked nouns (masculine nouns ended in $-o$ and feminine nouns ended in $-a$ ) and of nouns with gender-correlated but unmarked word-endings (e.g., $-ad$ ) was manipulated. The results showed that regularity affected reaction times and error rates only in the case of gender-marked nouns, suggesting that the mere statistical distribution of a word-ending across genders is not responsible for the regularity effect. In Experiment 2, gender-marked nouns and gender-unmarked nouns were preceded by a masked prime which could be a definite article (which provides information about the gender of the noun) or a possessive pronoun (which does not contain gender information). The presentation of the definite article led to shorter reaction times and less errors only when the word-ending was different from $-o$ or $-a$ . Taken together, these results indicate that gender assignment in Spanish is carried out through different processes depending on the noun ending: gender decisions for gender-marked nouns are based on the gender-to-ending distribution. Meanwhile, gender decisions for unmarked nouns seem to require the retrieval of the corresponding definite grammatical article, regardless of the statistical distribution of the noun ending across genders.     

Tourist Assessment of Archaeological Sites: The Case of The Archaeological Complex of Itálica (Seville,Spain)

ABSTRACT

Few studies have examined visitors’ assessments of their stay at archaeological complexes. This study analyzed this issue, focusing on Itálica (Seville, Spain). The results show that three factors are important in assessing a visit: quality of service, perceived sacrifice and satisfaction. With regard to these three factors, significant differences were found depending on whether the visitor had previously been to Itálica and where he or she came from. From these results, the authors have identified possible ways of improving the services provided, and, consequently, visitor satisfaction.     

Quality of Life and Mental Health Comparisons Among Liver Transplant Recipients and Cirrhotic Patients with Different Self-Perceptions of Health

Our aim was to analyze the differences in quality of life and mental health among liver transplant recipients with better (G₁) and worse (G₂) perceived health and decompensated cirrhotic patients (G₃). We selected two groups of patients: 168 liver transplant recipients and 75 cirrhotic patients. The Hospital Anxiety and Depression Scale and SF-36 Health Survey were used. Statistically significant differences showed that cirrhotic patients (G₃) suffered the highest impairment, and liver transplant recipients with better self-perceived health (G₁) had the lowest impairment, whereas patients with worse self-perceived health (G₂) were in an intermediate position between both groups. Moreover, very striking differences, based on large effect sizes, were found among groups on some quality of life dimensions: physical-role, general health, vitality, and physical functioning. In conclusion, the biopsychosocial well-being of liver transplant recipients is better than that of cirrhotic patients, even if the former do not perceive their health positively.     

Viewing Cognitive Conflicts as Dilemmas: Implications for Mental Health

The idea that internal conflicts play a significant role in mental health has been extensively addressed in various psychological traditions, including personal construct theory. In the context of the latter, several measures of conflict have been operationalized using the Repertory Grid Technique (RGT). All of them capture the notion that change, although desirable from the viewpoint of a given set of constructs, becomes undesirable from the perspective of other constructs. The goal of this study is to explore the presence of cognitive conflicts in a clinical sample (n = 284) and compare it to a control sample (n = 322). It is also meant to clarify which among the different types of conflict studied provides a greater clinical value and to investigate its relationship to symptom severity (SCL-90-R). Of the types of cognitive conflict studied, implicative dilemmas were the only ones to discriminate between clinical and nonclinical samples. These dilemmas were found in 34% of the nonclinical sample and in 53% of the clinical sample. Participants with implicative dilemmas showed higher symptom severity, and those from the clinical sample displayed a higher frequency of dilemmas than those from the nonclinical sample.     

Attention Deficit Hyperactivity Disorder,differential diagnosis with blood oxygenation,beta/theta ratio,and attention measures

Attention Deficit Hyperactivity Disorder (ADHD) is one of the disorders causing the greatest impact, conditioning academic learning, quality of concentration, and capacity for self-regulation and control. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV-TR) establishes the most commonly accepted criteria for diagnosis (Inattentive: ADHD-I, Hyperactive/impulsive: ADHD-HI, and Combined: ADHD-C), but currently, diverse studies disagree about whether to address it as a continuum with different degrees of intensity (subtype structure) or as specific disorders (counterposed profiles). Prior research has tested the hypothesis of differential categories with performance measures and cortical activation. The goal proposed herein is to confirm these results, incorporating a new measure, near-infrared hemoencefalography (nir-HEG), in order to control cortical activation through levels of blood oxygenation. For this purpose, we used a sample of 205 children between 8 and 13 years (105 control group, 28 with ADHD-I, 35 with ADHD-HI, and 37 with ADHD-C), administering a continuous performance test (TOVA), quantified electroencephalogram (Q-EEG), and nir-HEG. Results reflect the counterposed profiles hypothesis instead of the degrees of intensity, although the latter is more habitual and generalized.     

Overdetermination and Elimination

Abstract

I focus on two arguments, due to Jaegwon Kim and Trenton Merricks, that move from claims about the sufficiency of one class of causes to the reduction or elimination of another class of entity, via claims about overdetermination. I argue that in order to validate their move from sufficiency to reduction or elimination, both Kim and Merricks must assume that there can be no ‘weak overdetermination’; i.e., that no single effect can have numerically distinct but dependently sufficient causes occurring at the same time. One problem for both arguments is that weak overdetermination isn't obviously objectionable. That point has been well made before. But I want here to go further than merely shifting the burden of proof onto the advocates of overdetermination arguments. I want to tease out why they are so convinced that we must resist weak overdetermination and explain why their conviction is misguided. Both Merricks and Kim, I shall argue, ultimately rest their case on the same motivating principle, which I call the principle of additional causal powers. This principle, I argue further, should be rejected. It lacks argumentative support, and it begs the question against those at whom the arguments are directed.     

Mindfulness-based interventions in secondary education: a qualitative systematic review / Intervenciones basadas en mindfulness en educación secundaria: una revisión sistemática cualitativa

Abstract

In order to study the effects of mindfulness meditation interventions administered to adolescents within their educational institutions, a qualitative systematic review was conducted. Sixteen studies published in main databases were analysed. The results show that mindfulness, as a prevention strategy in educational contexts, resulted in significant changes in the followings variables: (a) psychological (e.g., reduction in depressive symptoms); (b) psychosocial (e.g., increased social skills); and (c) physiological (e.g., improvement of blood pressure). Although the results were conclusive, their interpretation and generalization should be carefully analysed as there were no medium- and long-term follow-up evaluations, in addition to the fact that there has been a minimal assessment of the psychological mechanisms involved in the change processes.
