THE USE AND IMPACT OF PSYCHOLOGY IN VENEZUELA: TWO EXAMPLES

Two cases are presented to illustrate how psychological knowledge and technology have been used in Venezuela. The first case relates to the use of psychological technology in Venezuelan politics where it is possible to identify a change from “caudillismo” to a more democratic “voting against” political culture. There is evidence that imported political compaigning techniques and extensive use of polling have been a factor of some importance in such change. The second case refers to the activities of the Minister for the Development of Intelligence, who has started a group of projects to improve cognitive functioning in different age groups. These programs are too recent to ascertain their effectiveness; so data is reported on an opinionative evaluation of one of the projects, carried out among Venezuelan psychologists and pediatricians.     

Social representations of drugs,causal judgment and social perception

The aim of this study was to analyse the influence of social representation on both social perceptions and social judgments. In the first stage of this study, 47 drug users and 80 ‘normal’ subjects were asked to respond to a questionnaire about representations of drugs. Three weeks later we contacted the same subjects. They were asked to answer some questions about a fictitious story in which an actor labelled as ‘a drug user’ or ‘a person’ disputed with a trader. Three different social representations of drugs were found. It was shown that these social representations were anchored in different social groups which were defined by their proximity to the world of drugs. Subjects who were themselves drug users shared an accepting or an ambivalent social representation of drugs but they also made the most negative judgements about the causes of a fictitious dispute between a trader and a drug addict. Moreover, these subjects had the most negative perception of the drug addict. Furthermore, some factors which increase the salience of social representations were studied. The effect on social perception and causal attributions of the interaction between social representations, the context and personal involvement in drugs was also shown. Some relations between the theory of social representations and the theories about asymmetrical intergroup relationships are exposed.     

Long-term outcome of sex therapy

In a prospective investigation of the long-term outcome of 140 couples who had entered sex therapy 1–6 yrs earlier for a variety of sexual dysfunctions, successful follow-up, mostly by interview, was possible with at least one partner in 75% of cases. While recurrence of sexual difficulties was common, coping strategies were identified which often helped overcome relapses. Improvements in couples' general relationships resulting from treatment were usually sustained. Long-term outcome was excellent for vaginismus, good for erectile dysfunction, but often poor for premature ejaculation, and especially, for female impaired sexual interest. While the results of this study support the continued use of sex therapy for sexual dysfunction, they also emphasize the need for new therapeutic approaches for problems with poor outcome, especially female loss of sexual interest.     

Improved picture naming in chronic aphasia after TMS to part of right Broca's area: an open-protocol study

Functional imaging studies with nonfluent aphasia patients have observed "over-activation" in right (R) language homologues. This may represent a maladaptive strategy; suppression may result in language improvement. We applied slow, 1 Hz repetitive transcranial magnetic stimulation (rTMS) to an anterior portion of R Broca's homologue daily, for 10 days in four aphasia patients who were 5-11 years poststroke. Significant improvement was observed in picture naming at 2 months post-rTMS, with lasting benefit at 8 months in three patients. This preliminary, open trial suggests that rTMS may provide a novel treatment approach for aphasia by possibly modulating the distributed, bi-hemispheric language network.     

Development of the comprehension and appreciation of fables

The authors proposed and tested a model of fable comprehension and appreciation. They proposed that fables are metaphoric in that they teach moral lessons about human activity, and that apprehension of the moral derives from a belief in a just world. In Study 1, children from kindergarten to 8th grade and college students received Aesop fables, reversed-outcome Aesop fables, and fable-like stories. As predicted, kindergartners and some 1st graders did not demonstrate a belief in a just world and did not differentiate between normal and reversed-outcome Aesop fables. Quality of morals provided by older participants was superior to that of younger participants. In Study 2, the quality of fable moral was found to be significantly correlated with quality of proverb and metaphor interpretation. Also, memory for goal or intention story elements was found to be related to quality of moral produced. Directions for future research are identified.     

WEIRDness abounds! Sample characteristics,restricted variance,and why they matter for international selection and assessment research

There is increasing awareness that reliance on samples from Western, Educated, Industrialized, Rich, Democratic (WEIRD) countries may have skewed our view of human phenomena. Nowhere is this more true than in international selection and assessment (ISA) research. In the present paper, we describe a way of understanding the impact of WEIRDness on ISA phenomena: restricted variance (RV). The WEIRDness problem is usually one of cross level interactions in which a country-level variable (e.g., individualism/collectivism) might moderate the relationship between two individual-level variables. RV can help to see not only where such cross level interactions might exist, but also provide a specific, mathematical reason for their existence. We use several examples from IJSA and related sources to illustrate the role of RV in ISA-based WEIRDness.     

Variations in stress responses following involvement in a railway suicide or attempted suicide

Three train drivers were interviewed one month after their involvement in a railway suicide or suicide attempt. The case studies demonstrate that reactions to these incidents vary from the severe and debilitating (concurrent diagnoses of post-traumatic stress disorder and neurotic depression) to the relatively mild (few reported symptoms). All train drivers reported a significant reduction in symptoms at a follow-up interview six months after the incident. Although the psychological effects of these incidents may be severe they appear to be time-limited.     

Physical activity and determinants of sedentary behavior in Brazilian adolescents from an underdeveloped region

The purpose of the study was to analyze the physical activity and the determinants of sedentary behavior in 1,268 Brazilian adolescents (638 girls, 630 boys) between the ages of 15 and 18 years, randomly selected from a relatively underdeveloped region. Data were collected from a community-based survey in the city of Jo?o Pessoa, Paraiba, Brazil. Information related to physical activity was derived on the short version of the International Physical Activity Questionnaire. The prevalence of sedentary behavior was 28.2% for girls and 19.1% for boys, whilst 28.9% of the girls and 36.7% of the boys showed high physical activity. The sedentary behavior varied by sociodemographic and environmental determinants studied. Parents' education, socioeconomic status, school's characteristics, transport to school, paid work, smoking, alcohol use, and BMI scores were significantly related to sedentary behavior for boys and girls.     

Marijuana-related problems and social anxiety: the role of marijuana behaviors in social situations

Individuals with elevated social anxiety appear particularly vulnerable to marijuana-related problems. In fact, individuals with social anxiety may be more likely to experience marijuana-related impairment than individuals with other types of anxiety. It is therefore important to determine whether constructs particularly relevant to socially anxious individuals play a role in the expression of marijuana-related problems in this vulnerable population. Given that both social avoidance and using marijuana to cope with negative affect broadly have been found to play a role in marijuana-related problems, the current study utilized a new measure designed to simultaneously assess social avoidance and using marijuana to cope in situations previously identified as anxiety-provoking among those with elevated social anxiety. The Marijuana Use to Cope with Social Anxiety Scale (MCSAS) assessed behaviors regarding 24 social situations: marijuana use to cope in social situations (MCSAS-Cope) and avoidance of social situations if marijuana was unavailable. In Study 1, we found preliminary support for the convergent and discriminant validity and internal consistency of the MCSAS scales. In Study 2, we examined if MCSAS scores were related to marijuana problems among those with (n = 44) and without (n = 44) clinically elevated social anxiety. Individuals with clinically meaningful social anxiety were more likely to use marijuana to cope in social situations and to avoid social situations if marijuana was unavailable. Of importance, MCSAS-Cope uniquely mediated the relationship between social anxiety group status and marijuana-related problems. Results highlight the importance of contextual factors in assessing marijuana-related behaviors among high-risk populations.     

Item response theory analysis of intimate-partner violence in a community sample

The Revised Conflict Tactics Scale (CTS2; Straus, Hamby, Boney-McCoy, & Sugarman, 1996) is a widely used measure of physical, psychological, and sexual aggression as well as injury and negotiation between partners. In this study, we analyzed male-to-female and female-to-male physical aggression using data from 453 community couples. We used item-response theory (IRT) to assess the range and precision of physical aggression severity in the past year, as evaluated by the CTS2. Our analyses support a single dimension of physical aggression with quantitative, rather than qualitative, differentiation between minor and severe physical aggression items. Surprisingly, test information curves revealed that male perpetration and victimization items provided as much or more information as their counterpart female victimization and perpetration items over the same range of aggression severity. Finally, the data suggests that CTS2 items best assessed moderate-to-severe levels of physical aggression in the previous 12 months. However, virtually no information was assessed by male or female reports of perpetration or victimization items below or around the mean of aggression (i.e., theta; θ = 0). Suggestions for improved item coverage and implications for the assessment of aggression are discussed.
