The WISC-R factoral validity for minority groups and Spearman's hypothesis

The factoral structure of the WISC-R for groups of Anglo, Black, and Mexican-American children was compared and found to be highly similar across groups. The tests appear to be measuring the same abilities in all three groups. The order of subtest difficulty was not significantly correlated with the subtest g loadings for the Black children but was for the Mexican-Americans. These results provide support for Spearman's hypothesis with Mexican-American children.     

Violent behavior in schizophrenic patients: relationship with clinical symptoms

Considerable evidence suggests that violent behavior observed in schizophrenic patients is motivated by psychotic symptomatology. The understanding of violence in schizophrenic patients requires consideration of psychiatric symptomatology. Objective: This study investigated the relationship between violent behavior and psychiatric symptomatology in schizophrenic patients. Method: One hundred and thirteen patients were recruited. Thirteen patients were excluded due to concomitant substance abuse six months prior to the assessment. Diagnoses were based on the SCID‐I. Psychotic symptom severity was assessed with the PANSS. Violent behaviors were assessed with the OAS. Results: Violent behaviors were associated with more severe psychotic symptomatology including hallucinations, delusions, excitement, poor impulse control, and thinking disturbances. Conclusions: Patients with exacerbation of psychotic symptomatology have an increased risk of violent behavior. It is necessary to determine which subtypes of hallucinations and delusions are implicated in the association of schizophrenia and violent behavior. Violent behavior in schizophrenic patients is a heterogeneous phenomenon best explained in the context of specific symptoms associated with violence and course of illness. The retrospective assessment of the variables raises methodological questions concerning the reliability of measurement of the impact of psychotic symptoms on violence. Aggr.

Foreign Workers’ Time Use in Spain: Evidence from the First Decade of the Twenty-First Century

The assimilation of immigrant workers to the Spanish labour market is a topic widely addressed by the economic literature. However, a little explored issue is the time allocation of immigrants and its effects on their integration and convergence to Spanish workers. This paper aims to study the time use of immigrants among different activities and the influence of personal and family characteristics on the participation and the amount of time spent in each activity. The results will be compared to those obtained for the native workers, in order to detect possible similarities and differences between both groups (immigrants versus natives). The data used come from the Time Use Survey for the periods 2002–2003 and 2009–2010 (INE, 2004, 2011), which allows analysing the evolution of the time use’s patterns of the immigrant and native workers at the beginning of the twenty-first century. Censored regression models are applied because the time spent in different activities is a left-truncated variable. The traditional approximation to the left-truncation is a Tobit model, but it assumes that the underlying process determining the participation and the time spent in each activity are similar, which is quite restrictive. To solve this restriction, a double hurdle model is applied.     

Individual differences in banknote processing: the role of altruism

We evaluated whether banknotes processing depended on altruism and attitude towards money. In Experiment 1, context effects were examined when participants named banknotes blocked by category or intermixed with pictures from semantic categories. Attitude towards money was assessed by questionnaires and the degree of altruism was evaluated with the dictator game task. In this task, participants received an amount of money and they had to decide whether to donate all, nothing or part of it. A facilitation effect was found in the banknote naming task and this effect increased as the amount of donations decreased. In Experiment 2, we examined whether less altruistic individuals might focus on the relevant information needed to process banknotes in a monetary Stroop task. Only more altruistic individuals showed Stroop effects. These results are interpreted as due to enhanced control while processing relevant information associated to banknotes in less altruistic individuals.     

Gaze following and gaze priming in lemurs

Although primates have often been found to co-orient visually with other individuals, members of these same species have usually failed to use co-orientation to find hidden food in object-choice experiments. This presents an evolutionary puzzle: what is the function of co-orientation if it is not used for a function as basic as locating resources? Co-orientation responses have not been systematically investigated in object-choice experiments, and requiring co-orientation with humans (as is typical in object-choice tasks) may underestimate other species’ abilities. Using an object-choice task with conspecific models depicted in photographs, we provide experimental evidence that two lemur species (Eulemur fulvus, n = 4, and Eulemur macaco, n = 2) co-orient with conspecifics. Secondly, by analysing together two measures that have traditionally been examined separately, we show that lemurs’ gaze following behaviour and ultimate choice are closely linked. Individuals were more likely to choose correctly after having looked in the same direction as the model, and thus chose objects correctly more often than chance. We propose a candidate system for the evolutionary origins of more complex gaze following: ‘gaze priming.’     

HIV‐Related Behaviors Among Prison Inmates: A Theory of Planned Behavior Analysis1

Prison inmates have high prevalence rates for both HIV and AIDS, creating a great need for HIV prevention efforts. We tested the theory of planned behavior (TPB) in 3 domains: intention to engage in condom use when released, intention to not share tattoo equipment in prison, and intention to not share needles or tattoo equipment when released. A total of 478 inmates (87% male) completed TPB and sexual and needle‐use risk behavior measures. TPB constructs accounted for a significant variance in intention to use condoms among African American, Hispanic, and Caucasian inmates, though the strength of the relationships differed by ethnicity. The TPB was less successful for intention to share tattooing equipment and not to share needles or tattoo equipment after release.     

Personality, cognitive coping strategies, and adaptational outcomes in a sample from the general Spanish population

The relationship among scores on two personality dimensions, Emotional Stability and Extraversion, and on two cognitive coping strategies, Positive Thinking and Wishful Thinking, and on the Consequences of Coping scale were examined in 169 Spanish persons (78 men and 91 women; Mage = 36.3 yr., SD = 12.1). Positive Thinking was associated with high scores on the two personality dimensions and positive consequences, whereas Wishful Thinking was associated with low scores on both Emotional Stability and Extraversion and with negative consequences.     

Influence of the penalty point system on driving behaviour: drivers' point of view

On July 1, 2006 a penalty point system was introduced in Spain. One year later, a reduction of 14.3% was observed in road traffic casualties, whilst the previous year that figure was 4.9%. A national telephone survey was conducted on a sample of 2.014 respondents to explore the drivers' point of view about the influence of the penalty point system on driving behaviour. Results point to a moderate behavioural change, mainly in relation to speeding and mobile phone misuse, this change being slightly more intense in drivers who were fined during the previous year. Awareness of road traffic accidents increased in around 40% of drivers. Lastly, mobility loss stands out as the most worrying and presumably most influential consequence of driving license loss.     

Impact of low-level expression dermatological diseases on the quality of life as a function of its level of specificity

The impact of dermatological diseases on the quality of life is relatively well established, although some results do not support this relationship. Whereas a few studies indicate a decrease in various indicators of quality of life in conditions of disease, in other studies, this effect has not been observed. These differences can be explained by the use of different concepts of quality of life and/or the comparison of different severity levels of the diseases. The purpose of this paper is to analyze the impact of low-level expression dermatological diseases on various concepts of quality of life. Two hundred-ninety-nine participants completed a questionnaire about symptoms, psychological and psychosocial impact, and general and specific satisfaction. Results show that minor dermatological diseases affect health-related quality of life, but not quality of life considered as well-being.     

Activation of lexical and syntactic target language properties in translation

Is reading for translation equal to reading in monolingual contexts? Horizontal/parallel theories of translation propose that normal reading and reading for translation differ because the translator engages in partial reformulation while reading for translating the source text. In contrast, vertical/serial theories assume that the translators first extract the meaning of the message, and only then they proceed to reformulate it. In two experiments, we manipulated lexical and syntactic properties of the target language (TL) while translators read for repetition or for translation. On-line sentence comprehension was affected by the lexical frequency of words in the TL (Experiment 1) and the syntactic congruency between the source language (SL) and TL sentences (Experiment 2). However, the influence of lexical and syntactic TL properties was restricted to the reading for translation task. According to our results, the horizontal view of translation includes code-to-code links between the SL and TL involving at least the lexical and syntactic level of processing.
