Beyond the abstract—concrete dichotomy: Mode of acquisition,concreteness, imageability,familiarity, age of acquisition,context availability,and abstractness norms for a set of 417 Italian words

The main objective of this study is to investigate the abstract-concrete dichotomy by introducing a new variable: the mode of acquisition (MoA) of a concept. MoA refers to the way in which concepts are acquired: through experience, through language, or through both. We asked 250 participants to rate 417 words on seven dimensions: age of acquisition, concreteness, familiarity, context availability, imageability, abstractness, and MoA. The data were analyzed by considering MoA ratings and their relationship with the other psycholinguistic variables. Distributions for concreteness, abstractness, and MoA ratings indicate that they are qualitatively different. A partial correlation analysis revealed that MoA is an independent predictor of concreteness or abstractness, and a hierarchical multiple regression analysis confirmed MoA as being a valid predictor of abstractness. Strong correlations with measures for the English translation equivalents in the MRC database confirmed the reliability of our norms. The full database of MoA ratings and other psycholinguistic variables may be downloaded from http:// brm.psychonomic-journals.org/content/supplemental or www.abstract-project.eu.     

Psychometric properties of the Psychosocial Risk Evaluation Battery for medium and small companies

The assessment of the presence and intensity of psychosocial risks is constant in research into Work Psychopathology. Many questionnaires and diagnosis systems are partial or else there is no standardization process or reliability and validity study. The main purpose of this work is to present the psychometric data of a multidimensional system to assess psychosocial risks, elaborated conjointly by the Universitat of Barcelona and the MC Mutual. This battery assesses companies, using information from the prevention technicians, the directive staff and the workers. With the diverse types of information, a triangulation proposal is established to offer a psychosocial risk profile linked to the evaluation needs.     

Discriminant validity of the ZKPQ in a sample meeting BPD diagnosis vs. normal-range controls

Widiger and Simonsen (2005) state that given the limitations of the categorical model of Personality Disorders classification proposals are to be expected for dimensional classifications. The purpose of this paper is to test the alternative five factorial model (AFFM) of personality in a sample with PDs. Subjects were administered the ZKPQ to test the discriminant capacity of the AFFM in classifying subjects diagnosed with BPD (n = 74) vs normal-range controls (n = 148) paired by age and sex, and identifying sensitive and/or specific dimensions that can be of help in diagnosing BPD. The results showed that high scores on N-Anx and Imp-SS, and low scores on Act are prognostic factors for being diagnosed with BPD. Likewise, this model correctly classified 88% of subjects with a kappa index of 0.73. The AFFM of personality appears to have a substantial power for predicting SCID-II interview-based BPD diagnosis.     

Does subjective well-being show a relationship between parents and their children?

The relationship between the subjective well-being of parents and their own 12–16-year-old children was explored in a Spanish sample of N = 266 families. A positive relationship was expected due to both a shared environment and the possibility of the genetic transmission of subjective well-being ‘set-points’. A positive significant relationship was found for the summated scale of satisfaction domains forming the Personal Well-being Index, and for the specific domains of health and security for the future. However, no relationship was found for the other five domains that make up this Index or for satisfaction with life as a whole. We conclude while these results provide some evidence for the expected influence of a shared environment, they have failed to provide evidence for high heritability of set-points for subjective well-being.     

Multimodal encoding in a simplified model of intracellular calcium signaling

Many cells use calcium signaling to carry information from the extracellular side of the plasma membrane to targets in their interior. Since virtually all cells employ a network of biochemical reactions for Ca²⁺ signaling, much effort has been devoted to understand the functional role of Ca²⁺ responses and to decipher how their complex dynamics is regulated by the biochemical network of Ca²⁺-related signal transduction pathways. Experimental observations show that Ca²⁺ signals in response to external stimuli encode information via frequency modulation (FM) or alternatively via amplitude modulation (AM). Although minimal models can capture separately both types of dynamics, they fail to exhibit different and more advanced encoding modes. By arguments of bifurcation theory, we propose instead that under some biophysical conditions more complex modes of information encoding can also be manifested by minimal models. We consider the minimal model of Li and Rinzel and show that information encoding can occur by AM of Ca²⁺ oscillations, by FM or by both modes (AFM). Our work is motivated by calcium signaling in astrocytes, the predominant type of cortical glial cells that is nowadays recognized to play a crucial role in the regulation of neuronal activity and information processing of the brain. We explain that our results can be crucial for a better understanding of synaptic information transfer. Furthermore, our results might also be important for better insight on other examples of physiological processes regulated by Ca²⁺ signaling.

Size of the attentional focus and efficiency of processing

By following Eriksen and St. James (1986) the experiments reported in this study focused upon three questions: (a) Can the spatial extent of the attentional focus be made to vary in response to precues? (b) As the area of the attentional focus increases, is there a decrease in processing efficiency for stimuli within the focus? (c) Is the boundary of the focus sharply demarked from the residual field or does it show a gradual dropoff? The results seem to provide answers to these questions: (a) the size of the attentional focus can be adjusted so that it covers areas of the visual field of different size; (b) there is a decrease in processing efficiency when the area of the attentional focus increases; and (c) there is a gradual dropoff in processing efficiency around the attentional focus.     

Activity measures in stress-attenuated novelty tests as possible analogues for extraversion in rats: Some experimental results

In an attempt to extend and validate Garcia-Sevilla's (1974) hypothesis proposing ambulation in a non-stressful open field (OF) as an animal analogue of human extraversion, ambulatory behaviour and rearing behaviour were studied and compared in several experiments with genetically-unselected rats. The effects of variation of OF auditory stimulation level, the correlation with a two-way avoidance-learning situation and the effects of a stimulant dose of d-amphetamine and an anxiolytic one of diazepam upon rearing and ambulatory behaviours were studied. All in all, our results support some of the requirements of the hypothesis, but also generate some additional problems. The results show that the number of rearings could be a better and more sensitive measure of variations in the level of arousal and a better predictor of shuttle-avoidance conditioning than ambulation. However, all activity measures are at least moderately intercorrelated, and they become grouped when results are factor analysed. All the results are discussed with reference to Eysenck's personality theory and Gray's anxiety theory, and it is concluded that these measures are too multidetermined and too poorly controlled to represent correctly and in a direct form a personality dimension such as Extraversion. Anyway, this attempt could be a good point of departure for discovering more efficient animal behavioural measures of arousability.
