Drug consumption and perception among Latin American immigrants

The aim of this study is to obtain information about drug consumption, leisure activities and knowledge of community services among Spanish-speaking immigrants to prevent drug abuse in this population. Quantitative methodology was used. The field work of this study has two phases: in the first stage (2003), a survey of social perception of drugs was administered to 147 subjects. During the second stage (2004), 610 surveys were administered. Data were analysed by bivariate analysis. Usual consumption of alcohol was 40.1%, usual consumption of tobacco was 31.3%, and usual consumption of cannabis was 3.4%. Drug users considered that the main reason for drug consumption was "to have fun" (p<.03). There is a relationship between leisure time and drug use. Family plays an important role in drug abuse prevention and preventive drug abuse programs must be adapted to this population.     

Behavioral problems in adolescents raised by their grandparents

This research analyzes, for the first time using a Spanish sample, the behavioral problems of adolescents in the custody of their grandparents. The sample consisted of 68 adolescents (31 boys and 37 girls, with a mean age of 13.7 years) in the custody of 54 grandparents with an average age of 65.9 years for the grandfathers, and 63.6 years for the grandmothers. The instrument employed was the Child Behavior Checklist (CBCL; Achenbach, 2001). The results indicate that the majority of both boys and girls can be classified within the normal range on scales of internal behavior, external behavior and total behavioral problems. When gender and age differences were analyzed, it was found that boys had more behavioral problems than girls on scales of incompliance with rules and external behavior. Meanwhile, it was shown that older adolescents had more somatic problems, as well as more behavioral problems, as measured by both the internal scale and total scale of the CBCL, than the younger participants.     

Adult age differences in attention to semantic context

In three experiments age differences in attention to semantic context were examined. The performance of younger adults (ages 18-29 years) and older adults (ages 60-79 years) on a semantic priming task indicated that both age groups could use information regarding the probability that a prime and target would be related to flexibly anticipate the target category given the prime word (Experiment 1). The timing by which target expectancies were reflected in reaction time performance was delayed for older adults as compared to younger adults, but only when the target was expected to be semantically unrelated to the prime word (Experiment 2). When the target and prime were expected to be semantically related, the time course of priming effects was similar for younger and older adults (Experiment 3). Together the findings indicate that older adults are able to use semantic context and the probability of stimulus relatedness to anticipate target information. Although aging may be associated with a delay in the timing by which controlled expectancies are expressed, these findings argue against an age-related decline in the ability to represent contextual information.     

Induced Cross-Modal Synaesthetic Experience Without Abnormal Neuronal Connections

ABSTRACT— Are the kinds of abnormal cross-modal interactions seen in synaesthesia or following brain damage due to hyperconnectivity between or within brain areas, or are they a result of lack of inhibition? This question is highly contested. Here we show that posthypnotic suggestion induces abnormal cross-modal experience similar to that observed in congenital grapheme-color synaesthesia. Given the short time frame of the experiment, it is unlikely that new cortical connections were established, so we conclude that synaesthesia can result from disinhibition between brain areas.     

Gender Differences in the Representation of Violence on Spanish Television: Should Women be More Violent?

Gender differences in the representation of aggressors and victims are an important issue in the study of television violence in order to ascertain whether television contributes (and how) to reproduce or transform the traditional gender regime. Eighty-four hours of Spanish main TV broadcasting stations were randomly recorded during years 2000 and 2005. Variables related to the presentation of aggressors and victims and to the normative context of aggression were selected through content analysis. The results show the minimal presence of women in violent scenes. But women are also the victims of more serious violence. Paradoxically, women’s aggressions appear to have more positive consequences and to be less legitimized. The implications of these findings are discussed from a gender studies perspective.     

Autonomic and psychologic correlates in hypertension and duodenal ulcer

Psychophysiologic response patterns of 47 male duodenal-ulcer patients, 50 male hypertensive patients, and a control group of 65 men were compared by recording skin resistance level and responses, finger pulse volume, and surface integrated electromyograms during a series of verbal, acoustic, and color stimuli. Personality characteristics were examined on the basis of the Eysenck Personality Inventory, the Lüscher Test, Juhász’ Neurosis Scoring Scale, and the Achievement Anxiety Scale of Alpert and Haber. Using stepwise discriminant analysis of these psychophysiologic data for the control and the hypertensive groups and the control and duodenal ulcer groups, errorless postdiction of group membership was obtained, which indicates that the autonomic parameters and psychologic traits selected as characteristics show relationships that are relevant from the diagnostic viewpoint in the groups of patients. The method could be developed into a screening test procedure for use in the early detection of persons potentially at risk.     

Depression secondary prevention in primary care

In order to analyse efficacy, effectiveness and efficiency of several depression secondary prevention programs, three group interventions were developed in Primary Care Centres: cognitive-behavioral therapy, promotion of one's coping resources therapy (just paying attention to abilities, without training) and social support. The sample was composed by 60 people with from-mild-to-moderate depressive symptoms, who were randomly assigned either to any of the treatments or to a control group (waiting list). Psychopathology, quality of life and attendance to mental health services variables were assessed at pretest, posttest and two follow-up evaluations, 6 and 12 months afterwards. Outcomes: both therapies had more efficacy, effectiveness and efficiency compared to the social support group, and this one was better than the waiting list.     

Daily life activity patterns among the elderly: is what they claim to do what they wish to do?

This study is aimed at exploring daily and desired activity patterns in a sample of older people, as well as at examining some influence factors and their relationships to life satisfaction. Our sample was made of 154 retired people living in urban areas and whose age was greater than 60 years old. Data about activities were gathered by means of an interview while life satisfaction scores were obtained by applying LSI scale. Our results show how the pattern of activities that our participants say to have done yesterday is quite similar to an ideal pattern, although in the ideal day time spent with other people is far greater. Factors like gender and economic and educational level have an influence on patters of activity, especially on instrumental and leisure ones. The difference between yesterday and ideal activities was negatively related to life satisfaction. Such a relationship was modest, but reached statistical significance.     

Symmetry and repetition in perspective

Although ecologically relevant, perspective views of symmetries and repetitions have hardly been investigated. Any symmetry or repetition that is not oriented orthogonally to the line of sight yields perspective distortions on the retina. In this study, these distortions are analyzed in terms of first-order structures (i.e., virtual lines between corresponding points) and second-order structures (i.e., correlation quadrangles formed by two virtual lines). In the literature, these structures have been proposed to guide the detection of fron to parallel symmetry and repetition. But what about perspective views? First, the analysis in this study shows that perspective distorts the retinal first-order and second-order structures of symmetry and repetition differently. Second, the results of two experiments on this distortion difference suggest that, in perspective views, symmetry and repetition detection is not preceded by normalization but occurs directly on the basis of the retinal first-order and second-order structures.
