Additions are biased by operands: evidence from repeated versus different operands

Recent evidence led to the conclusion that addition problems are biased towards overestimation, regardless of whether information is conveyed by symbolic or non-symbolic stimuli (the Operational Momentum effect). The present study focuses on the role of operands in the overestimation of addition problems. Based on the tie effect, and on recent evidence that the nature of operands biases addition problems towards an underestimation when operands are repeated, but towards an overestimation when different, we aim here to further elucidate the contribution of operands to addition problems. Experiment 1 replicates the underestimation of repeated-operand additions and overestimation of different-operand additions, with large numbers (around 50), and explores whether these effects also apply to small operand additions (around 10). Experiment 2 further explores the overestimation of different-operand additions by investigating the roles of operand order and numerical distance between operands. The results show that both factors have an impact on the overestimation size, but are not crucial for overestimation to occur. The results are discussed in terms of arithmetic strategies, spatial organization of numbers and magnitude representation.     

Men in the Office,Women in the Kitchen? Contextual Dependency of Gender Stereotype Activation in Spanish Women

In a set of two studies, we tested whether gender-stereotypical associations are automatically activated by Spanish women in a categorization task, and how this process is conditioned by the context in which the target is presented (kitchen vs. office). We hypothesized that gender stereotypes would be activated implicitly when the target (men vs. women) appeared in an office context (associated with male dominant roles), but not when they appeared in a kitchen context (traditionally associated with female roles). The studies were conducted with two samples (N?=?44; N?=?47) of female undergraduate students from the University of Granada (Spain). In both studies, a priming effect was found, indicating that a traditional, role-congruent stereotype pattern (men-competence, women-warmth) emerged when primes appeared in an office context, but not in a kitchen context. Further, negative competence traits were evaluated faster when a male prime was presented in the context of a kitchen (role-incongruent). The purpose of Study 2 was to clarify the implicit nature of this contextual contingency effect by manipulating the controllability of the priming effect (i.e., Stimulus Onset Asynchrony duration-SOA, and restricted response time). The results of Study 1 were replicated in only the short SOA condition, which implies faster and presumably less controlled processing of the stimuli. Theoretical implications for stereotyping and gender role research are discussed.     

‘We Are All the Same,We All Are Mestizos’: Imagined Populations and Nations in Genetics Research in Colombia

In Colombia, as in other Latin American countries, current population genetics research is based on the understanding that Colombians constitute a mestizo nation, given the admixture process that took place between Africans, Amerindians, and Europeans during colonial times. The mestizo is a pervasive category used by geneticists to conduct, organise, and publish research studies that deal with the continent's peopling process and the genetic makeup of its contemporary population(s). It is also the dominant imaginary for the Colombian population and a key nation-building ideology. By tracing how this category moves and is used across four Colombian genetics laboratories, it is possible to discern that despite its apparently clear-cut boundaries, the mestizo is contingent, contested, and flexible, allowing for multiple understandings and usages. This flexibility and multiplicity are visible in the quantification of genetic ancestry, the divisions of geographical location, and the understanding of gender. Such understandings allow one to think about a homogeneous nation (inclusive) that is simultaneously heterogeneous (exclusive); they provide multiple but not necessarily contradictory possibilities of being mestizo, allowing the coexistence of images of the nation that could otherwise seem contradictory; and they permit navigation around contested terms such as race, while simultaneously thinking of mixed races or racialised individuals. Finally, these flexible and multiple constructions of the mestizo (re)produce various subjects as ‘other’, whether they are women, the Indigenous, the black/dark, or the poor.     

Engaged at Work and Happy at Home: A Spillover–Crossover Model

The current diary study among 50 Spanish dual-earner couples examines whether engagement at work has an impact on own and partners’ well-being. Based on the Spillover–Crossover model, we hypothesized that individuals’ work engagement would spill over to the home domain, increasing their happiness level at the end of the day. Moreover, we predicted a crossover of happiness between the members of the couple. Participants filled in a diary booklet during five consecutive working days (N = 100 participants and N = 500 occasions). The results of multilevel analyses showed that daily work engagement has a direct effect on daily happiness. We also found that employees’ daily work engagement influenced partner’s daily happiness through employees’ daily happiness. Finally, results showed a clear bidirectional crossover of daily happiness between both members of the couple. These findings indicate that the positive effects of work engagement go beyond the work setting and beyond the employee.     

Brain processing of task-relevant and task-irrelevant emotional words: An ERP study

Although there is evidence for preferential perceptual processing of written emotional information, the effects of attentional manipulations and the time course of affective processing require further clarification. In this study, we attempted to investigate how the emotional content of words modulates cerebral functioning (event-related potentials, ERPs) and behavior (reaction times, RTs) when the content is task-irrelevant (emotional Stroop Task, EST) or task-relevant (emotional categorization task, ECT), in a sample of healthy middle-aged women. In the EST, the RTs were longer for emotional words than for neutral words, and in the ECT, they were longer for neutral and negative words than for positive words. A principal components analysis of the ERPs identified various temporospatial factors that were differentially modified by emotional content. P2 was the first emotion-sensitive component, with enhanced factor scores for negative nouns across tasks. The N2 and late positive complex had enhanced factor scores for emotional relative to neutral information only in the ECT. The results reinforce the idea that written emotional information has a preferential processing route, both when it is task-irrelevant (producing behavioral interference) and when it is task-relevant (facilitating the categorization). After early automatic processing of the emotional content, late ERPs become more emotionally modulated as the level of attention to the valence increases.     

Receptive and Productive Recall with the Keyword Mnemonics in Bilingual Students

The efficacy of keyword mnemonics in the learning of the non-dominant language in bilingual students was assessed. Of a total of 237 Compulsory Secondary Education students who participated in the study, 102 students used keyword mnemonics and 100 students used the rote method to learn the Spanish meaning of a list of 20 Galician words (the remaining 35 students generated the keywords to be used in the study). Moreover, each participant’s image control was assessed. The recall of the meaning of words was greater in the keyword mnemonics group than in the rote learning group both in terms of receptive and productive recall. Moreover, participants with high image control had better recall than those with low image control ability.     

Clinical Practice With Cases of Extreme Traumatization 40 Years After the Military Coup in Chile (1973–1990): The Impact on the Therapists

This paper presents our clinical experience with patients who were severely traumatized by the systematic violation of human rights during the military dictatorship in Chile (1973–1990). The lack of recognition of trauma of sociopolitical origin encapsulates the traumatic experience and forces it to remain as part of the present. Clinical vignettes of two therapeutic processes—mother and son—are presented: The mother was detained; sexually tortured; and, as a result of this, gave birth to the torturer’s son. Her therapeutic process is an account of her ambivalence towards her son, of how his origins were kept a family secret, and of how this secret was unconsciously transmitted. The young man’s therapeutic process centers on the transgenerational transmission of trauma and how the torturer–tortured dynamic seeps into the relationship with the analyst. The impact on the analysts’ subjectivity in working with extreme trauma is described.     

BMI,age, Mate Value,and Intrasexual Competition in Chilean Women

Attractiveness is the most important component of women intrasexual competition and it certainly has an impact in female’s perceived mate value (i.e., the value of an individual to the opposite sex as a potential mate). In the realm of intrasexual competition women are eager to emphasize their attractiveness and compete with rivals displaying these cues. Accordingly, age is an important feature of women’s appeal to the opposite sex; youth is highly valued by men, and is perceived by women as an important component of their attractiveness. Another trait that is a reliable cue of health and fertility is Body Mass Index (BMI). A large body of literature has associated BMI to female attractiveness. However, more information is necessary about the associations of BMI and age with mate value, and female intrasexual competition. In the present research we report two studies that examined the associations of BMI and age with estimates of self-perceived mate value and intrasexual competition in Chilean women (18–39 years). More specifically, we hypothesized inverse relationships of BMI and age with mate value (N?=?234), and intrasexual competition (N?=?308). We found partial support to our propositions. The results revealed inverse associations between BMI, mate value and mating success, but BMI with intrasexual competition were not related. In contrast, age had a strong and negative effect on intrasexual competition. We discuss our results within the framework of Evolutionary Psychology and consider the central role of attractiveness (estimated from BMI and age) in the mating strategies of women.
