Effects of non-symbolic numerical information suggest the existence of magnitude-space synesthesia

In number-space synesthesia, numbers are visualized in spatially defined arrays. In a recent study (Gertner et al. in Cortex, doi: 10.1016/j.cortex.2012.03.019 , 2012), we found that the size congruency effect (SiCE) for physical judgments (i.e., comparing numbers' physical sizes while ignoring their numerical values, for example, 8) was modulated by the spatial position of the presented numbers. Surprisingly, we found that the neutral condition, which is comprise solely of physical sizes (e.g., 3), was affected as well. This pattern gave rise to the idea that number-space synesthesia might entail not only discrete, ordered, meaningful symbols (i.e., Arabic numbers) but also continuous non-symbolic magnitudes (i.e., sizes, length, luminance, etc.). We tested this idea by assessing the performance of two number-space synesthetes and 12 matched controls in 3 comparative judgment tasks involving symbolic and non-symbolic stimuli: (1) Arabic numbers, (2) dot clusters, and (3) sizes of squares. The spatial position of the presented stimuli was manipulated to be compatible or incompatible with respect to the synesthetic number-space perceptions. Results revealed that for synesthetes, but not for controls, non-symbolic magnitudes (dot clusters) as well as symbolic magnitudes (i.e., Arabic numbers) interacted with space. Our study suggests that number-space synesthetes might have a general magnitude-space association that is not restricted to concrete symbolic stimuli. These findings support recent theories on the perception and evaluation of sizes in numerical cognition.     

Indiscriminate behavior observed in the strange situation among institutionalized toddlers: Relations to caregiver report and to early family risk

Socially disinhibited or indiscriminate behavior (IB) has traditionally been investigated using caregiver reports. More recently, an observational measure based on the Strange Situation Procedure (M. Ainsworth, M. Blehar, E. Waters, & S. Wall, 1978), the Rating of Infant and Stranger Engagement (RISE; C. Riley, A. Atlas‐Corbett, & K. Lyons‐Ruth, 2005), was validated in home‐reared at‐risk children. The present study aimed to validate the RISE in an institutionally reared sample using the caregiver report, to assess whether IB assessed with the RISE was elevated among the institutionalized children, and to explore potential risk factors associated with IB. The study was conducted among 74 institutionalized toddlers aged 11 to 30 months. Sociodemographic questionnaires were used to assess pre‐admission experiences, and aspects of institutional placement were coded from the children's files in the institution and staff's report. Institutionalized children displayed high frequencies of IB as assessed on the RISE, and this instrument was validated against caregiver report. Pre‐admission experiences of the institutionalized children in their biological families—namely, prenatal risk and maternal emotional neglect risk—predicted IB. Results suggest that the RISE is adequate to use among institutionally reared toddlers and point to aspects of the early familial environment that may be implicated in IB.     

Is an optimistic memory less easily influenced by negative than by positive emotions?

This work examines whether a positive personality trait, such as optimism, can reduce bias in differential words recalled after inducing a certain emotion. After showing a list of words with various emotional valences to a group of 59 subjects, a specific emotional state was induced. Subsequently, the subjects were asked to recall the list of words. The results obtained indicated that less optimistic subjects had a tendency to recall and recognize a greater number of negative words when in a negative emotional condition. Statistical significance was reached in the female group's negative word recognition when experiencing negative emotion.     

Reliability and validity evidence of the Out-group Threat Perception Scale (OTPS)

This study aimed to analyze the psychometric properties of a new scale: the Out-group Threat Perception Scale (OTPS). The OTPS was designed to measure the perception of out-group threat, an important psychosocial variable that is closely related to negative attitudes towards out-groups. Three hundred and two Spanish participants responded to the OTPS in reference to the following out-groups: Moroccans (N= 102), Romanians (N= 101) and Ecuadorian immigrants (N= 99). The reliability and item analyses showed that the scale had good internal consistency. Factor analyses yielded two independent dimensions: Realistic Threat and Symbolic Threat. Correlational analyses showed that the OTPS correlated significantly with several psychosocial variables. The present findings suggest that the OTPS is a reliable and valid measure, and it can be a useful instrument to study intergroup relationships in our country.     

The multidimensional nature and multicultural validity of a new measure of social anxiety: the Social Anxiety Questionnaire for Adults

Much has been written about the situations most often feared by persons with social phobia, and several self-report measures are frequently used to assess such feared situations. However, it is not clear whether the situations feared by persons with social phobia form unidimensional or multidimensional factors. If these situations are multidimensional, reliance on a total score of feared situations would not reflect important differences between those dimensions. This research examined the multidimensional nature and multicultural validity of a newly developed instrument (the Social Anxiety Questionnaire for Adults [SAQ-A]) in two studies with a total of 539 patients diagnosed with social phobia and 15,753 nonpatients from 20 different countries. The structure (five clear and solid factors) and psychometric properties of the final instrument (the SAQ-A30) support the multidimensional nature of social anxiety and provide a new perspective in the assessment of social phobia.     

Low diversity and low frequency of participation in leisure activities compromise working memory efficiency in young adults

People perform leisure activities (LA) every day; pursuits that entail applying cognitive, physical and social abilities. As in old age, doing LA during early and middle adulthood is related to a reduced risk of dementias, probably by generating a cognitive reserve. As it is possible that a relation between doing LA and working memory (WM) efficiency exists in young adults, we assessed whether the diversity and frequency of LA are related to WM efficiency in this population. Ninety-three healthy young subjects solved the n-back task at two levels of difficulty (2, 3), and answered an LA questionnaire on the activities in which they had participated in the month prior to the experiment. Subjects were classified separately on their scores for (1) diversity (high/low) and (2) frequency (high/low) in order to test the relation between each variable and WM efficiency. Though no differences were found, a subsequent analysis of the average of diversity and frequency ratios of LA performance taken together-the diversity/frequency index-showed that low diversity plus low frequency was significantly associated with reduced WM efficiency at this age; results that suggest that frequent participation in diverse LA during youth is related to WM efficiency.     

Parental and Secondary School Teachers’ Perceptions of ICT Professionals, Gender Differences and their Role in the Choice of Studies

The influence of parents and teachers in the decisions made by adolescents regarding study options has not been widely documented in Spain. The main aim of this qualitative study consisted of analyzing the opinions of parents and secondary school teachers about their role in the different academic and professional choices boys and girls make. Seven focus groups (4 with 27 parents and 3 with 22 secondary school teachers) from 5 schools located in urban and rural areas of Catalonia (Spain) were carried out in order to explore how both groups perceive Information and Communication Technology (ICT) professionals, gender differences in study options and their own role in adolescents’ choice of study options. Our findings show that parents and teachers hold stereotypes about ICTs and consider that gender does not condition adolescents’ study choices. Both groups saw themselves as playing a secondary role in adolescents’ academic and professional choices. Some gender differences among parents and teachers emerged regarding their perception of the ICT professionals and their own role and of others in shaping adolescents’ study choices.?The findings and their practical implications are discussed.     

Attack efficacy in volleyball: elite male teams

The goal was to identify performance indicators predicting attack efficacy in volleyball's game phase denominated Complex II, i.e., the counter-attack. 28 games from the 2007 Men's World Cup were analyzed. Attack efficacy was predicted by three primary variables: Attack tempo, Attack type, and Number of blockers. Power attack and Attack tempo 1 increased the probability of an Attack point. The supremacy of Attack tempo 3 and the high frequency of Two blockers and Three blockers reflected the difficulty of efficient attack during Complex II. Despite unfavourable conditions, attackers managed to execute Power attacks in the majority of the situations, and score a high frequency of Attack points.     

Analysis of the US-preexposure effect in flavor acceptance conditioning

In three experiments, rats received exposure to a sucrose solution followed by conditioning with a neutral flavor as the conditioned stimulus (CS) and sucrose as the unconditioned stimulus (US). In Experiments 1 and 2, some rats were given both the preexposure and the conditioning phases in a highly familiar context (the homecage), whereas other animals received both phases in a novel and distinctive context. In both cases the magnitude of the conditioning effect was reduced by preexposure to the US. Experiment 3 directly assessed the possible role of contextual cues by changing the context between the exposure phase and the conditioning phase but found no loss of the US-preexposure effect in these conditions. These results lend no support to the blocking-by-context account of the US-preexposure effect; alternative interpretations are considered.     

A Liberation Psychology Approach to Acculturative Integration of Migrant Populations

This paper describes an acculturative integration approach that stresses the contribution of liberation psychology. Immigrant integration is a challenge for receiving countries in the Western world due to the frequent asymmetrical and oppressive conditions suffered by newcomers in their new settlements. The cross-cultural perspective connects integration with psychological acculturation, emphasizing harmony between acquisitions of the new culture while maintaining cultural heritage, and creating opportunities for intergroup relationships. In turn, liberation psychology permits an understanding of the acculturative transition as an empowerment and self-construction process by which immigrants acquire a new vision of the world and of themselves, transforming both structural conditions and themselves. From this perspective we conceptualize acculturative integration as the process by which newcomers become an accepted part of the new society through a reflexive and evaluative process, changing their social references and position, rebuilding their social and personal resources, and achieving a new agency in coherence with their new challenges and goals. In this process, they acquire critical thinking about unequal conditions, gain capacities to respond to the inequalities, and take effective actions to confront them. We illustrate this process using the narratives of nine Moroccan women who are living in asymmetrical and oppressive local contexts in Andalusia, the southern-most region of Spain.
