In the late 1930s, the Institute of Human Relations of Yale University developed a research program on conflict and anxiety as an outcome of Clark Hull's informal seminar on the integration of Freud's and Pavlov's theories. The program was launched at the 1937 Annual Meeting of the APA in a session chaired by Clark L. Hull, and the experiments continued through 1941, when the United States entered the Second World War. In an effort to apply the findings from animal experiments to the war situation, John Dollard and Neal E. Miller decided to study soldiers' fear reactions in combat. As a first step, they arranged interviews with a few veterans of the Abraham Lincoln Brigade. Taking these interviews as a point of departure, Dollard devised a questionnaire to which 300 former Lincoln brigaders responded. The present paper analyzes the main outcomes of the questionnaire, together with the war experiences reported in the interview transcripts. Our purpose was to evaluate a project which was initially investigated by the FBI because of the communists among the Lincoln ranks, but eventually supported by the American Army, and which exerted great influence on the military psychology of the time.

We examined the memory for central and peripheral information concerning a crime and the acceptance of false information. We also studied eyewitnesses' confidence in their memory. Participants were shown a video depicting a bank robbery and a questionnaire was used to introduce false central and peripheral information. The next day the participants completed a recognition task in which they rated the confidence of their responses. Performance was better for central information and participants registered more false alarms for peripheral contents. The cognitive system's limited attentional capacity and the greater information capacity of central elements may facilitate processing the more important information. The presentation of misinformation seriously impaired eyewitness memory by prompting a more lenient response criterion. Participants were more confident with central than with peripheral information. Eyewitness memory is easily distorted in peripheral aspects but it is more difficult to make mistakes with central information. However, when false information is introduced, errors in central information can be accompanied by high confidence, thus rendering them credible and legally serious.

Emotional (pleasant or unpleasant) and neutral scenes were presented foveally (at fixation) or peripherally (5.2° away from fixation) as primes for 150 ms. The prime was followed by a mask and a centrally presented probe scene for recognition. The probe was either identical in specific content (i.e., same people and objects) to the prime, or it was related to the prime in general content and affective valence. The probe was always different from the prime in color, size, and spatial orientation. Results showed an interaction between prime location and emotional valence for the recognition hit rate, but also for the false alarm rate and correct rejection times. There were no differences as a function of emotional valence in the foveal display condition. In contrast, in the peripheral display condition both hit and false alarm rates were higher and correct rejection times were longer for emotional than for neutral scenes. It is concluded that emotional gist, or a coarse affective impression, is extracted from emotional scenes in peripheral vision, which then leads to confuse them with others of related affective valence. The underlying neurophysiological mechanisms are discussed. An alternative explanation based on the physical characteristics of the scene images was ruled out.

There is currently a widespread interest in indexing and extracting taxonomic information from large text collections. An example is the automatic categorization of informally written medical or psychological diagnoses, followed by the extraction of epidemiological information or even terms and structures needed to formulate guiding questions as an heuristic tool for helping doctors. Vector space models have been successfully used to this end (Lee, Cimino, Zhu, Sable, Shanker, Ely & Yu, 2006; Pakhomov, Buntrock & Chute, 2006). In this study we use a computational model known as Latent Semantic Analysis (LSA) on a diagnostic corpus with the aim of retrieving definitions (in the form of lists of semantic neighbors) of common structures it contains (e.g. “storm phobia”, “dog phobia”) or less common structures that might be formed by logical combinations of categories and diagnostic symptoms (e.g. “gun personality” or “germ personality”). In the quest to bring definitions into line with the meaning of structures and make them in some way representative, various problems commonly arise while recovering content using vector space models. We propose some approaches which bypass these problems, such as Kintsch's (2001) predication algorithm and some corrections to the way lists of neighbors are obtained, which have already been tested on semantic spaces in a non-specific domain (Jorge-Botana, León, Olmos & Hassan-Montero, under review). The results support the idea that the predication algorithm may also be useful for extracting more precise meanings of certain structures from scientific corpora, and that the introduction of some corrections based on vector length may increases its efficiency on non-representative terms.

Learning to read is one of the most important cognitive milestones in the human social environment. One of the most accepted models explaining such process is the Double-Route Cascaded Model. It suggests the existence of two reading strategies: lexical and sublexical. In the Spanish language there are some contradictions about how these strategies are applied for reading. In addition, there are only a few studies dealing with the analysis of shifts between them, achieving a fluent reading process. In this paper we use a reading task including words and pseudowords for characterizing the cost of shifting between reading strategies in children with developmental dyslexia and normal controls. Our results suggest the presence of both strategies in these two experimental groups. In controls, both strategies become more efficient in correspondence to the increased exposition to written material. However, in children with developmental dyslexia only the lexical strategy exhibits such improvement. Their also point to a low cost for shifting between strategies in controls and a much more significant one in children with developmental dyslexia, differentiating subgroups with distinct shifting patterns.

Since the decade of 1980, the model of stress and coping proposed for the assessment of vulnerability of adoptive families emphasizes that the emotional adjustment of those adopted is moderated by variables such as institutionalization, the manner and age at which the adoption was revealed, the change of first name, and the contact with the biological family. The objective of this study was to investigate the relationship of these variables to the perceived parenting style, mood, and self-esteem of the adopted adolescents. Participants in the study were 68 adolescents, between the ages of 14 and 15, adopted during infancy through judicial channels. The adolescents responded to a questionnaire about the history of adoption and to scales of Parenting Styles, Depression and Self-esteem. The main results indicated that the late revelation of adoption and the change of the first name are connected to higher levels of depression and low self-esteem and to more frequent perceptions of negligent or authoritarian parenting style. The contact with the biological family was frequently mentioned among those who perceived their parents as authoritative and presented the best indicator of mood and self-esteem. These findings were discussed in light of the necessity for multidisciplinary actions which can improve the psychological adaptation of the adopting families.

School adjustment is one the greatest challenges in residential child care programs. This study has two aims: to analyze school adjustment compared to a normative population, and to carry out a multi-source analysis (child, classmates, and teacher) of this adjustment. A total of 50 classrooms containing 60 children from residential care units were studied. The “Método de asignación de atributos perceptivos” (Allocation of perceptive attributes; Díaz-Aguado, 2006), the “Test Autoevaluativo Multifactorial de Adaptación Infantil” (TAMAI [Multifactor Self-assessment Test of Child Adjustment]; Hernández, 1996) and the “Protocolo de valoración para el profesorado (Evaluation Protocol for Teachers; Fernández del Valle, 1998) were applied. The main results indicate that, compared with their classmates, children in residential care are perceived as more controversial and less integrated at school, although no differences were observed in problems of isolation. The multi-source analysis shows that there is agreement among the different sources when the externalized and visible aspects are evaluated. These results are discussed in connection with the practices that are being developed in residential child care programs.

The aim of this study is to describe some characteristics of the sexual behavior of adolescents in Spain and to compare these characteristics according to gender, using a cross-sectional survey. Participants were 1.279 male and female adolescents who reported having had sexual intercourse. A questionnaire about sexual behavior was applied at their high schools and during school hours. Data were collected between 2006 and 2007. Mean age at the onset of sexual intercourse was 14.8 years in males and 15.0 years in females. Males and females were different according to the type of partner at the last sexual intercourse: 63.0% of males had a steady partner compared to 90.5% of females (p<0.01). The mean number of sexual partners during the last 12 months was higher in males than in females (M = 2.1 and M = 1.5 partners, for males and females, respectively, p<0.01). 50.0% of males had sexual intercourse under the effects of drugs versus 39.3% of females (p<0.01). STD and HIV prevention programs should be designed considering the differences according to adolescents’ sex.

Under the perspective of the Theory of Planned Behavior, the objective of this study was to know the gender differences in the variables involved in the use of effective preventive measures in sexual relations against HIV in a sample of university students from Spain and Portugal. Furthermore, it is examined whether these factors produce different predictions concerning the adoption of safe sexual behaviour for young man and women in each country. The sample consisted of 683 university students, 319 Portuguese (64% female and 36% male) from the University of Algarve and 364 Spanish students (51% female and 49% male) from the University of Huelva. Data were obtained by means of a questionnaire. The data revealed that there are gender differences which apply in both countries, highlighting that the young women have more positive attitudes, greater perceived behavioural control and intention of condom use than young men. However, they protect themselves less that their male counterparts: the percentage of females who say using condoms as a contraceptive method is less than the percentage of males, and especially with their steady partners. The results are discussed in relation to gender role norms, to have a steady partner or not, gender relations, the associated meaning to sexual relations for men and women and their implications for the design of sexual educational programmes for them.

One hundred and fifty-five mothers of children with attention deficit/hyperactivity disorder (ADHD) completed a semi-structured interview, the Parenting Stress Index Questionnaire (Abidin, 1990), to evaluate parenting stress. The Parenting Scale (Arnold, O'Leary, Wolff & Acker, 1993) was also administered to measure dysfunctional discipline strategies. Structural equation modeling was used to test a model in which the independent variables were the Child's Characteristics and the Socio-Educational Status of his or her family; intermediate variables were Parenting Stress concerning the Child Domain and concerning the Parent Domain; and the dependent variable was Parental Discipline. The results confirm our hypotheses. Interventions in these families should therefore incorporate a component focused on Parenting Stress (in both the Child Domain and the Parent Domain), as a determinant of Parental Discipline.

Developmental contexts have been studied in terms of systems of beliefs and practices, treated as part of general cultural models. This paper aims to describe aspects of parenting cultural models of a group of 200 primiparous Brazilian mothers from Rio de Janeiro, who had children less than 44 months old. Mothers answered the Socialization Goals Interview (SGI), and an adapted version of an inventory of beliefs about practices of care, developed by M. Suizzo. Answers to the SGI were coded in five categories and their subcategories: Self-maximization (SM), Self-control (SC), Lovingness (L), Proper demeanor (PD) and Decency (D), and scores in each of them were calculated. A factor analysis indicated three dimensions of mothers' beliefs about practices: Awaking and exposing the child to diverse stimuli (Stimulation), ensuring the Proper presentation of the child and Responding to and bonding to the child. Data was further analyzed in terms of subcategories of SM and D and of the relation to the factors mothers' educational level and sex of their child. Results showed that mothers from Rio de Janeiro share a cultural model of autonomy for their children, but that they also believe in the importance of their relationship to others.

This study examined estimates of their own, and their parents' general and multiple intelligences. Three hundred and twenty three students from East Timor, and one hundred eighty three students from Portugal estimated their own, and their parents' IQ scores on each of Gardner's ten multiple intelligences. Men believed they were more intelligent than were women on mathematical (logical), spatial, and naturalistic intelligence. There were consistent and clear culture differences. Portuguese gave higher self, and family ratings than Timorese, as expected. Participants of both cultures rated overall intelligence of their father higher than that of their mother. Implications of these results for education and self-presentations are considered.

In the present study, 151 British and 151 French participants estimated their own, their parents' and their partner's overall intelligence and 13 ‘multiple intelligences.’ In accordance with previous studies, men rated themselves as higher on almost all measures of intelligence, but there were few cross-national differences. There were also important sex differences in ratings of parental and partner intelligence. Participants generally believed they were more intelligent than their parents but not their partners. Regressions indicated that participants believed verbal, logical-mathematical, and spatial intelligence to be the main predictors of intelligence. Regressions also showed that participants' Big Five personality scores (in particular, Extraversion and Openness), but not values or beliefs about intelligence and intelligences tests, were good predictors of intelligence. Results were discussed in terms of the influence of gender-role stereotypes.

In this study we analyzed gender differences in the intensity of habitual guilt, as well as those in interpersonal sensitivity and the tendency towards experiencing feelings of guilt with a high anxious-aggressive component. The 360 participants (adolescents, young adults and adults) were asked to relate one of the situations that most frequently caused them to experience guilt and to rank its intensity and that of 9 other emotions they may have experienced at the same time on a 7-point scale. These scales were used to obtain the scores for the anxious-aggressive component of guilt. Two interpersonal sensitivity measures were used: the IRI Empathic Concern scale and an ad hoc measure focusing on the guilt produced by interpersonal events (Interpersonal Guilt). Habitual guilt was found to be more intense in women than in men in all age groups. The results suggest that this difference is linked to differences in interpersonal sensitivity and the tendency to experience types of guilt with a high anxious-aggressive component.

This article presents the results of a series of preliminary comparisons, between the Portuguese and Romanian cultural contexts, on the individualism-collectivism (IND/COL) cultural dimension. The IND/COL was evaluated with the Individualism-Collectivism Questionnaire – ICQ –, constructed in New Zealand by Shulruf, Hattie and Dixon (2003, Anonymous Questionnaire of Self-Attitudes –AQSA), and adapted to the Portuguese and Romanian contexts by Ciochină and Faria (2007), using studies of confirmatory factor analysis. The ICQ composed by 26 items, 15 evaluating the IND scale– with three subscales (Uniqueness, Competition and Responsibility) –, and 11 evaluating the COL scale – with two subscales (Harmony and Advice) –, was administered to 395 subjects, 200 Portuguese and 195 Romanian, 10th and 12th graders. On the whole, in the Portuguese and Romanian samples, the multivariate and univariate statistical analyses evidenced the existence of two independent variables – gender and cultural context –, with significant effects, main and of interaction, on the scales and subscales of the ICQ. The results were discussed taking into consideration the specificities of the educational systems in the two cultural contexts, which are inevitably shaped by socio-cultural factors characteristic of the two countries considered in the present study – Portugal and Romania.

This study's interest relies on adolescents' social representations of unprotected sex, more precisely on the relationship between the attitude towards the preservative and the reason attribution for its non use. 1386 secondary school students took part in the study, in the Brazilian cities of Florianópolis, Itajaí and Balneário Camboriú. In order to verify reasons attributed by the students, we focused on the sample that had sexual experiences without using the condom during last year. Data was analyzed with software ALCESTE, which showed three different classes of explanations for the non use of the preservative: the moment of the intercourse (unpredictable and incontrollable), trust in the partner and the option of the contraceptive pill, instead of the preservatives, in avoiding pregnancy. The students' attitudes towards the preservative are less favourable among those who maintain sexual intercourse with known people. The results revealed two representations of AIDS: one of trust in the partner and another of the experience with sex and the preservative – the first one gives sense to the adolescents' experiences with known sexual partners and the second, with less known sexual partners.

Different studies regarding the role of norms on the expression of prejudice have shown that the anti-prejudice norm influences people to inhibit prejudice expressions. However, if norm pressure has led to a substantial decrease in the public expression of prejudice against certain targets (e.g., blacks, women, blind people), little theoretical and empirical attention has been paid to the role of this general norm regarding sexual minorities (e.g., prostitutes, lesbians and gays). In this sense, the issue we want to address is whether general anti-prejudice norms can reduce the expression of prejudice against homosexual individuals. In this research we investigate the effect of activating an anti-prejudice norm against homosexuals on blatant and subtle expressions of prejudice. The anti-prejudice norm was experimentally manipulated and its effects were observed on rejection to intimacy (blatant prejudice) and on positive-negative emotions (subtle prejudice) regarding homosexuals. 136 university students were randomly allocated to activated-norm and control conditions and completed a questionnaire that included norm manipulation and the dependent variables. A multivariate analysis of variance (MANOVA) as well as subsequent ANOVAS showed that only in the high normative pressure condition participants expressed less rejection to intimacy and less negative emotions against homosexuals, when compared to the simple norm-activation and the control conditions. Positive emotions, however, were similar both in the high normative pressure and the control conditions. We concluded that a high anti-prejudice pressure regarding homosexuals could reduce blatant prejudice but not subtle prejudice, considering that the expression of negative emotions decreased while the expression of positive emotions remained stable.

The consequences of work-related stress on health are worrisome, and by the same token, so is Burnout Syndrome. However, it has been shown that social support can prevent, reduce or even combat individuals' responses to stress.

A descriptive, transverse study was carried out with the objective of determining the prevalence of both Burnout Syndrome and receiving social support for traffic police in Mexico. 875 traffic police participated in the study, men and women alike, from all work shifts, day and night. Three questionnaires were administered: one to record sociodemographic and professional data, as well as the Maslach Burnout Inventory and the modified Diaz Veiga Social Resources Inventory. Our data analysis obtained frequencies and percentages and also identified associations between the study's variables.

The prevalence of Burnout Syndrome was found to be 54.9% among the study's participants. The social support networks designated as “low or poor” were shown to be associated with Burnout Syndrome, with p values less than .05, an odds ratio (OR) greater than 1 and a confidence interval that did not include the number one.

In spite of the strong network of social support reported by participants, it seems that those social effects were not strong enough to combat Burnout Syndrome, and some resolution strategy ought to be implemented at the individual, group and organizational levels.

This study examines levels of occupational stress, quality of life, work-related stressors, and coping strategies among senior police officers in Brazil. A quantitative questionnaire survey conducted among 418 senior members of the São Paulo Police Force reveals that high-ranking Brazilian police officers perceive their profession as being very stressful. A large proportion (43%) of police officers are found to have significant stress symptoms. A greater proportion of females (54%) than males (40%) are found to have stress. The most frequently reported stressor is interaction with other departments within the police force. Quality of life is found to be deficient in the ‘professional’ and ‘health’ areas. This study is the first to show a clear association between high levels of emotional stress and poor quality of life in Brazilian police officers. The large number of stress symptoms and poor quality of life identified in the present study indicates that there is a need for preventive actions inside the Brazilian police force to motivate lifestyle changes, improve stress-management skills, and promote a better quality of life among high-ranking police officers.

Usually, well-being has been measured by means of questionnaires or scales. Although most of these methods have a high level of reliability and validity, they present some limitations. In order to try to improve well-being assessment, in the present work, the authors propose a new complementary instrument: The Implicit Overall Well-Being Measure (IOWBM). The Implicit Association Test (IAT) was adapted to measure well-being by assessing associations of the self with well-being-related words. In the first study, the IOWBM showed good internal consistency and adequate temporal reliability. In the second study, it presented weak correlations with explicit well-being measures. The third study examined the validity of the measure, analyzing the effect of traumatic memories on implicit well-being. The results showed that people who remember a traumatic event presented low levels of implicit well-being compared with people in the control condition.
