The role of personal values and basic traits in perceptions of the consequences of immigration: a three-nation study

Using data from Italy, Spain, and Germany (N= 1,569), this study investigated the role of basic values (universalism and security) and basic traits (openness and agreeableness) in predicting perceptions of the consequences of immigration. In line with Schwartz's (1992) theory, we conceptualized security as having two distinct components, one concerned with safety of the self (personal security) and the other with harmony and stability of larger groups and of society (group security). Structural equation modelling revealed that universalism values underlie perceptions that immigration has positive consequences and group security values underlie perceptions that it has negative consequences. Personal security makes no unique, additional contribution. Multi-group analyses revealed that these associations are invariant across the three countries except for a stronger link between universalism and perceptions of the consequences of immigration in Spain. To examine whether values mediate relations of traits to perceptions of immigration, we used the five-factor model. Findings supported a full mediation model. Individuals' traits of openness and agreeableness explained significant variance in security and universalism values. Basic values, in turn, explained perceptions of the consequences of immigration.     

The effects of sleep deprivation on the attentional functions and vigilance

The study of sleep deprivation is a fruitful area of research to increase our knowledge of cognitive functions and their neural basis. In the current work, 26 healthy young adults participated in a sleep deprivation study, in which the Attentional Networks Test for Interactions and Vigilance (ANTI-V) was performed at 10a.m. after a night of normal sleep and again at 10 a.m. after 25.5-27.5 h of total sleep deprivation. The ANTI-V is an experimental task that provides measures of alerting, orienting and executive control attentional functions. Compared with previous versions, the ANTI-V includes a vigilance task, more reliable auditory alerting signals, non-predictive peripheral orienting cues, and also a neutral no-cue condition allowing the analysis of reorienting costs and orienting benefits. Thus, new evidence to evaluate the influence of sleep deprivation on attentional functioning is provided. Results revealed differences in both tonic and phasic alertness after sleep deprivation. Vigilance performance was deteriorated, while a warning tone was more helpful to increase participants' alertness, resulting in slightly faster RT and, in particular, fewer errors. The reorienting costs of having an invalid spatial cue were reduced after sleep loss. No sleep deprivation effect on the executive control measure was found in this study. Finally, since no control group was used, particular precautions were taken to reduce the influence of potential practice effects.     

Asymmetry in human cognition: further replication and extension

Vladimir Lefebvre proposed an algebraic model of self-reflexion in the 1980s. He viewed reflexion as a product of the structure and computational rules of Gamma algebra and his equations are considered metaphors for how consciousness is structured. From the framework of this model, Lefebvre hypothesized an asymmetry in human cognition. One of the early studies supporting his model was conducted by Victorina Lefebvre. Over the years, other studies have been conducted, but not all have shown similar support as the original findings of Victorina Lefebvre. This study attempted to extend her findings in testing whether or not other ambiguous stimuli could be used in support of the model.     

Tolerance towards dating violence in Spanish adolescents

The study of intimate partner violence among adolescent and young couples in Spain remains unattended, although such abuses are well known and more frequent than in adulthood. The aim of this study is, on the one hand, to provide epidemiological information on dating relationships, and on the other hand, to identify attitudes towards violence. 2205 women enrolled in schools in diverse provinces of Spain, participated in the study. Average age was near 19 years (SD= 2.25). The Dating Violence Questionnaire (DVQ, in Spanish, CUVINO), a questionnaire that assesses both frequency and distress associated with violent behavior, was used. The DVQ allowed differentiating between groups of women self-labeled as abused and not abused on the basis of the frequency of sustained violence, although the levels of distress in the face of violence were statistically similar in both groups. Implications for future research and prevention programs are discussed.     

Psychometric properties of the Spanish version of the Thougth-Shape Fusion Questionnaire

The objectives of the study were to analyze the psychometric properties, factor structure and internal consistency of the Spanish version of the Thought-Shape Fusion Questionnaire (TSF-Q), as well as to determine its validity by evaluating the relationship of the TSF-Q to different instruments. Two groups were studied: one comprising 146 patients with a diagnosis of anorexia (n = 82), bulimia (n = 33) or unspecified eating disorder (n = 31), and another group of 115 undergraduates with no history of psychological disorder. All participants completed the TSF-Q, TAF-Q, EDI-2, STAI, BDI and SCL-90-R. Differences in TSF-Q scores between the diagnostic subgroups were also analyzed. Two factors were obtained which coincided with the two sections indicated by the authors of the questionnaire: conceptual and interpretative. The internal consistency of the TSF-Q and its subscales was determined by means of Cronbach's alpha, with values ranging between .93 and .96. The correlations with other instruments reflected adequate validity. There were no significant differences between the diagnostic subgroups. The Spanish version of the TSF-Q meets the psychometric requirements for measuring thought-shape fusion and shows adequate internal consistency and validity.     

The effect of white-noise mask level on sinewave contrast detection thresholds and the critical-band-masking model

It is known that visual noise added to sinusoidal gratings changes the typical U-shaped threshold curve which becomes flat in log-log scale for frequencies below 10c/deg when gratings are masked with white noise of high power spectral density level. These results have been explained using the critical-band-masking (CBM) model by supposing a visual filter-bank of constant relative bandwidth. However, some psychophysical and biological data support the idea of variable octave bandwidth. The CBM model has been used here to explain the progressive change of threshold curves with the noise mask level and to estimate the bandwidth of visual filters. Bayesian staircases were used in a 2IFC paradigm to measure contrast thresholds of horizontal sinusoidal gratings (0.25-8 c/deg) within a fixed Gaussian window and masked with one-dimensional, static, broadband white noise with each of five power density levels. Raw data showed that the contrast threshold curve progressively shifts upward and flattens out as the mask noise level increases. Theoretical thresholds from the CBM model were fitted simultaneously to the data at all five noise levels using visual filters with log-Gaussian gain functions. If we assume a fixed-channel detection model, the best fit was obtained when the octave bandwidth of visual filters decreases as a function of peak spatial frequency.     

COCAINE ADDICTS AND THEIR FAMILIES: AN EMPIRICAL STUDY OF THE PROCESSES OF IDENTIFICATION

The processes of identification between adolescent cocaine addicts and their parents were studied in 402 subjects, in total 134 familial triads (father"mother"son), subdivided into two groups of 67 triads, one of these groups having as the child an adolescent of masculine sex dependent on cocaine and the other, equal in number, being a control group, duly matched for age and socio-economic status. The instrument employed was the Rorschach test (1922), limited to the application of the Lerner Defense Scale (LDS; Lerner & Lerner, 1980). The findings in the affected triads showed up as consistent statistically for the presence of intense processes of pathological identification, especially between father and son, a sign of the importance of the presence of disturbances of paternal function in the development of this addiction. The utilisation of very regressive defence mechanisms, above all of projective identification, was the predominant mode of procedure in triads with a dependent child. In comparisons between the fathers the odds ratio (OR) for projective identification was 8.66 to 1, which points to the association between cocaine addiction and the primitive mental functioning of the fathers. With empirical methodology these findings serve to corroborate the psychoanalytical conclusions based on studies of single case studies, testifying that the dysfunctions of identificatory phenomena in familial functioning are predominant in the mental organisation of cocaine addicts.     

Can empathic concern be generalized from one person to others? Another positive side of the ‘one‐among‐others’ effect

Previous research on the one‐among‐others effect has shown that inducing empathic concern towards a victim presented among other individuals in need enhances: (1) awareness of these others and (2) the willingness to help them individually. In this work, we test that these outcomes are linked by an additional process: the generalization of empathic concern felt for the victim towards the others in need. Study 1 revealed that inducing empathic concern for a victim presented as one‐among‐others led to see the others as separate and different individuals, not as a unitary group. Study 2 showed that the one‐among‐others presentation (vs. only‐one‐victim) increased empathic concern towards those presented along with the main victim. Study 3 showed that the one‐among‐others presentation (vs. a single‐victim or a statistical presentation) increased the empathic concern felt for other individuals in need. Therefore, the one‐among‐others presentation does not weaken empathic concern but, instead, it leads to its generalization from one to others.     

Visual behavior and perception of trajectories of moving objects with visual occlusion

Experienced athletes in sports with moving objects have shown greater skill when using visual information to anticipate the direction of a moving object than nonexperienced athletes of those sports. Studies have shown that expert athletes are more effective than novices in occlusion situations in the first stages of the sports sequence. In this study, 12 athletes with different competitive experience in sports with moving objects viewed a sequence of tennis ball launches with and without visual occlusion, launched by a ball-shooting machine toward different areas with respect to the participant's position. The relation among visual behavior, occlusion time, and the precision of the task is reviewed. The spot where the balls bounced was analysed by a digital camera and visual behavior by an Eye Tracking System. Analysis showed that the nonexperienced athletes made significantly more errors and were more variable in visual occlusion conditions. Participants had a stable visual search strategy.
