Links between sex-related expectations about alcohol, heavy episodic drinking and sexual risk among young men in a shantytown in Lima, Peru

CONTEXT: Alcohol use is frequently identified as a contributor to risky sexual behaviors; however, research results are mixed. Given the conflicting evidence, researchers have focused on other factors, such as expectations about alcohol's effects that might help explain the relationship of alcohol use and risky sexual behaviors. METHODS: Cross-sectional data from 312 sexually experienced males aged 18-30 in a shantytown in Lima, Peru, were used in logistic regression models to identify associations of heavy episodic drinking and sex-related expectations about alcohol with sexual risk behaviors. RESULTS: Heavy episodic drinking was associated with having had two or more sexual partners and having had sex with a casual partner in the past year (odds ratios, 2.8 and 2.5, respectively). After controlling for alcohol consumption, sex-related expectations about alcohol were associated with these high-risk sexual behaviors, as well as with not using a condom at last sex (1.2) and not using a condom at last sex with a casual partner (1.3). CONCLUSION: Beliefs about the effect of alcohol on sexual performance could help explain links between alcohol consumption and risky sexual behavior not completely accounted for by the pharmacological effects of alcohol.     

Effects of Tradislexia videogame on phonological awareness and word recognition in dyslexic children

The purpose of this research was to analyze the effects of multimedia training on phonological awareness and word recognition in dyslexic children. We used a control pretest-posttest design, and a sample of 62 children (26 male, 36 female) was selected from Primary Education. Children were selected and classified into two different groups: (1) an experimental group (N=32), and (2) a control group (N=30). The average range age was 9 and 12 years (M=126.7, SD=11.7). We administered phonological awareness tasks, which include different types of syllabic structure from the Sicole-R Multimedia Battery for assessment of cognitive processes in reading. We analyzed whether the Tradislexia videogame affected phonological awareness, considering separately the complexity of syllable structure and type of phonological awareness task. We also analyzed whether the gains in phonological processes were related to training based on type of task or type of syllable structure. The results showed that when we controlled the position of phoneme, the multimedia treatment in segmentation and blending with words that include CV syllables is a better predictor to explain improvement of word decoding processes.     

The effect of personality variables in the prediction of the execution of different prospective memory tasks in the laboratory

The study of prospective memory (ProM), the remembering of the delayed execution of intentions, has been growing in recent years, and we know quite a bit about the cognitive variables that affect it. But the performance of a task depends on personality variables as well as on cognitive ones, and the role of personality variables in ProM has only been partially studied, the results being less conclusive. We sought to address two main objectives: (1) to quantify the joint influence of cognitive and personality variables on three ProM tasks in the laboratory (two based on events and the other on time), and (2) to identify the personality profiles of those who perform well in these three ProM tasks as opposed to those who do not. The cognitive and personality variables were evaluated with two sessions of 157 participants. The 16 PF-5 was applied (Cattell, Cattell & Cattell, 1993) and other cognitive variables were measured. With the data obtained, we ran several regression analyses to determine how some cognitive variables (sustained attention, verbal fluency, interference, retrospective memory, selective attention) and personality factors (tested using the 16 PF-5) can help to explain the variance in the performance of prospective memory tasks. Our results show that the contribution of personality predictor variables is moderate and smaller than that of the cognitive variables for predicting the execution of ProM tasks in the laboratory. Furthermore the intervention of the personality variables differs depending on the ProM tasks used. Global self-control and rule-consciousness were the personality variables that contributed the most in the prediction of the scores in the ProM tasks that were used.     

Motivations underlying attitudes: regulatory focus and majority versus minority support

Drawing on regulatory focus theory, the present work examined the motivations underlying intergroup attitudes expressed under conditions of majority versus minority support. In two studies, participants expressed their attitudes towards equality and non‐discrimination of foreigners and were informed that the equality and non‐discrimination principle was supported by either a majority or a minority. Regulatory focus was assessed as the extent to which participants felt promotion‐related and prevention‐related emotions when acting either inconsistently or consistently with the egalitarian principle. Results provided evidence supporting the hypothesis that attitudes are related to prevention emotions when supported by a majority, but to promotion emotions when supported by a minority.

Multiple victimization of Spanish adolescents: a multilevel analysis

Multiple victimization in adolescence is an issue that has received little research attention. Furthermore, adolescents are particularly vulnerable to victimization in different contexts. The aim of this study is to analyze correlates of multiple victimization in three contexts (home, school, and street). The following forms of victimization were considered: stealing, hitting, insulting, threatening, blackmailing, and weapon intimidation. Multiple victimization correlates explored were: sex, age, public/private school, socioeconomic status, quality of family relationships, and antisocial behavior. A probabilistic sample of 1,908 adolescents (ages 13 to 18) was used. Multilevel analyses were conducted to separate correlates at the individual level from those operating at the contextual level. Results show that gender, quality of family relationships, and deviant behavior were related to multiple victimization in adolescence.     

On the role of regular phonological variation in lexical access: evidence from voice assimilation in French

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate "bagage" 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be.     

负面身体自我女性对身体信息的记忆偏向： 来自ERP研究的证据

采用事件相关电位（ERPs）技术探讨了负面身体自我女性（大学生）对胖-瘦两类身体图片进行再认时的脑内时程动态变化。结果发现,相对于控制组（正常女大学生）,胖负面身体自我女大学生在750~800ms的时间窗口内,“胖图”比“瘦图”诱发出一个更正的ERP波形,差异波的地形图显示该正成分在中前部有更强的激活。进一步对差异波作偶极子溯源分析,结果发现,该正成分主要起源于右侧枕叶附近。这似乎表明,右侧枕叶的激活与身体自我信息的出现有关,与负面身体自我图式的体验有关     

Discriminant validity of the ZKPQ in a sample meeting BPD diagnosis vs. normal-range controls

Widiger and Simonsen (2005) state that given the limitations of the categorical model of Personality Disorders classification proposals are to be expected for dimensional classifications. The purpose of this paper is to test the alternative five factorial model (AFFM) of personality in a sample with PDs. Subjects were administered the ZKPQ to test the discriminant capacity of the AFFM in classifying subjects diagnosed with BPD (n = 74) vs normal-range controls (n = 148) paired by age and sex, and identifying sensitive and/or specific dimensions that can be of help in diagnosing BPD. The results showed that high scores on N-Anx and Imp-SS, and low scores on Act are prognostic factors for being diagnosed with BPD. Likewise, this model correctly classified 88% of subjects with a kappa index of 0.73. The AFFM of personality appears to have a substantial power for predicting SCID-II interview-based BPD diagnosis.     

Motivational profiles and flow in physical education lessons

The purpose of this study was to use cluster analysis to identify differences in goal orientation and motivational climate profiles among students in physical education classes as well as differences among the observed clusters on perceived flow experiences. 983 students of 14- to 15-yr.-olds (M = 14.8 yr., SD = 0.91) from a large Spanish metropolitan school district were participants and completed questionnaires assessing goal orientations, motivational climates, and perceived flow. Analysis showed three distinct clusters with 40.3% of the sample with a High Motivation cluster, 27.6% in a Low Motivation cluster, and 32.2% in a Mastery Motivation cluster. These three clusters differed significantly in ratings of perceived flow. Clusters also showed different composition by sex. Implications of these results with regard to instruction in physical education classes are discussed.     

当代医药卫生改革的话语逻辑

运用语言哲学的方法分析了目前中国关于深化医药卫生体制改革意见的话语方式和文本内容,认为,如何划分医药卫生体系往往是界定问题和言语行动的逻辑前提,也是最重要的话语权的体现;“看病难”和“看病贵”可能是被误读的流行语;文件说什么,如何说,这是一种影响政府和市场行为的言语行为;如果作为医改指导思想的核心概念的语义含糊不清,那么,就难以保证言语行为的正确了。
