Quality of life in patients with alcohol dependence disorder with personality disorders: relation to psychological adjustment and craving

The purpose of this study is to determine the self-perceived quality of life of abstinent patients with alcohol dependence disorder during the first month of treatment, and how the presence of personality disorders, psychological adjustment, and the level of craving affect this perception. For this purpose, a sample was used comprising 65 participants with mean age of 43.26 years, of whom 70.8% were male and 29.2% female, with a mean duration of addiction to alcohol consumption of 11.83 years. The results show that quality of life is not related to the duration of abstinence or the course of the addiction. Moreover, the patients who present a personality disorder perceive poorer quality of life in areas such as health status, mood, and social relations. Self-perception of quality of life is affected by psychological adjustment and beliefs about craving. These data should be taken into account when considering quality of life as a measurement of the effectiveness of a treatment for drug addicts with personality disorders.     

Risk and protective factors in adolescents' drug use, and differences by age and sex

Adolescents' drug use has huge social and personal implications, so it is essential to identify risk and protective factors. In this research, the CTCYS was used with 2440 adolescents to detect risk and protective factors for drug use in the community, family, school and peers/individual; differences in risk and protective factors by age and sex; and relationships between risk and protective factors and substance use. Protective factors are high. Risk factors are high in the community, the school and the individual. Older adolescents have more risks and less protection than the youngest; and there are sex differences, because males have less protection and more risks. The risk factors more closely related to drug use are availability of drugs in the community, family attitudes favourable to drug use, family history of antisocial behaviour, early start and use of drugs by friends, perceived risk and attitudes favourable to drug use. In the protective factors, the role played by social skills for alcohol use is important.     

Effect of a retention interval between pre-exposure and conditioning on latent inhibition in humans using a blink conditioning procedure

Latent inhibition, retarded learning after pre-exposure to the to-be-conditioned stimulus, was examined using a blink conditioned procedure in humans. Experiment 1 showed that the procedure is suited to inducing the latent inhibition effect. In Experiment 2, the introduction of a 3-minute interval between pre-exposure and conditioning phases attenuated latent inhibition. These results contribute to identify the mechanisms involved in pre-exposure and subsequent conditioning of a stimulus, which is particularly important if we bear in mind that latent inhibition has been used repeatedly as an instrument to analyze the course of attentional processes in normal and pathological populations.     

Syndromes or symptoms in the assessment of aphasic patients?

The procedure generally used to diagnose aphasic patients consists of classifying them in one of the classic syndromes on the basis of the analysis of their symptoms. However, this taxonomy has several important problems, the main one being that it does not take into account the variability of aphasic patients, as there are many more disorder profiles than those included in the syndromes. In order to test the homogeneity of a sample of patients diagnosed with the classic taxonomy, 15 aphasic patients (5 Broca, 5 Wernicke and 5 Conduction) and 5 healthy controls were tested with nine comprehension and production tasks. Participants were aged 38 to 81 years old. The results indicate the existence of great variability in patients labeled with the same diagnosis, as revealed by the differences in within-group scores in each task, and a limited adjustment to the expected profile, with some patients showing symptoms allegedly corresponding to other syndromes. Our results call attention to the need to study each patient individually and interpret their disorders regardless of the syndromes.     

Assessment of the global intelligence and selective cognitive capacities in preterm 8-year-old children

The aim of this study was to assess various cognitive abilities such as attention, IQ, reasoning, and memory related to academic achievement in 8- and 9-year-old preterm children. A total of 141 children were assessed. The preterm group (=37 weeks) comprised 63 children and was compared to 78 full-term children. Attention was evaluated using the d2 Selective Attention test, and the IQ by the L-M form of the Stanford-Binet Intelligence Scale, establishing a profile of abilities: perception, memory, comprehension, reasoning, and verbal fluency. Significant differences in IQ were found between the preterm and full-term children. Of the cognitive abilities assessed, the only significant differences were found in verbal fluency, with preterm boys showing lower verbal fluency scores than full-term children. In conclusion, all preterm groups have attention ability similar to that of full-term children. However, preterm children obtain lower scores in intelligence measures. In addition, preterm boys have verbal fluency difficulties. Taking into account the increase in preterm births, suitable intervention programs must be planned to attend the difficulties found.     

Blockade of nucleus basalis magnocellularis or activation of insular cortex histamine receptors disrupts formation but not retrieval of aversive taste memory

Recent research, using several experimental models, demonstrated that the histaminergic system is clearly involved in memory formation. This evidence suggested that during different associative learning tasks, histamine receptor subtypes have opposite functions, related to the regulation of cortical cholinergic activity. Given that cortical cholinergic activity and nucleus basalis magnocellularis (NBM) integrity are needed during taste memory formation, the aim of this study was to determine the role of histamine receptors during conditioned taste aversion (CTA). We evaluated the effects of bilateral infusions of 0.5 μl of pyrilamine (100 mM), an H₁ receptor antagonist, into the NBM, or of R-α-methylhistamine (RAMH) (10 mM), an H₃ receptor agonist, into the insular cortex of male Sprague-Dawley rats 20 min before acquisition and/or retrieval of conditioned taste aversion. The results showed that blockade of H₁ receptors in NBM or activation of H₃ receptors in the insular cortex impairs formation but not retrieval of aversive taste memory. These results demonstrated differential roles for histamine receptors in two important areas for taste memory formation and suggest that these effects could be related with the cortical cholinergic activity modulation during CTA acquisition.     

Language Shift and the Inclusion of Indigenous Populations in Large-Scale Assessment Programs

Indicators of academic achievement for bilingual students can be inaccurate due to linguistic heterogeneity. For indigenous populations, language shift (the gradual replacement of one language by another) is a factor that can increase this heterogeneity and poses an additional challenge for valid testing. We investigated whether and how indigenous populations can be validly included in a large-scale assessment program. We gave Mexican preschool Mayan students aged 5 to 6 years the same set of mathematics items in three versions: (1) original in Spanish, (2) Mayan translation, and (3) content equivalent, developed from scratch in Mayan. Also, we collected information on the students’ and the teachers’ use of Spanish and Mayan, and on the communities’ support of the two languages. Students performed poorly on the three versions. Generalizability theory-based analyses revealed considerable performance inconsistency across items and language versions and low generalizability and dependability coefficients. This performance instability appears to stem from a dwindling support of the Mayan language in Mayan schools and communities. Fair, valid assessment of indigenous populations in either their languages or their countries’ dominant languages appears to be difficult to accomplish with current testing models and policies.     

Effects of Decision Training on Decision Making and Performance in Young Tennis Players: An Applied Research

This study examined the effectiveness of a 10-week decision training program on decision making and performance in tennis. Decision training was based on the analysis combining tactical questioning and video feedback about players own actions. A quasi-experimental design with intermediate tennis players (control group, n = 6; experimental group, n = 5) was developed over 18 weeks, divided into 3 phases: preintervention, postintervention, and retention. A total of 13,383 game play actions were analyzed to test differences. Experimental group improves significantly decision making and performance and maintained improvements during the retention phase. Video feedback combined with questioning is recommended to achieve sport expertise.     

AUTISM TREATMENTS IN PRINT: MEDIA'S COVERAGE OF SCIENTIFICALLY SUPPORTED AND ALTERNATIVE TREATMENTS

Professionals, celebrities, and media frequently suggest to parents the possible treatment options for their children with autism. Some treatment recommendations advocate for scientifically supported treatments whereas others suggest novel, untested interventions, or potentially ineffective or harmful treatments. The current study examined the print media's coverage of applied behavior analysis (ABA) and non‐scientifically supported autism treatments. Over the last 10 years, print media have increasingly published articles referring to autism treatments with little scientific support and a decreased coverage of ABA. Print media's positive statements about non‐scientifically supported treatments also increased over the last decade, whereas positive statements about ABA decreased. ABA received two times as many positive comments as negative; however, non‐scientifically supported treatments as a group received four times as many positive comments as negative. These results could contribute to parents' decisions to implement treatments for their children with autism. To contribute to future positive perception of ABA, we provided suggestions for the dissemination of information to increase positive reporting of ABA in print media.
