Eye movements blink the attentional blink

When presented with a sequence of visual stimuli in rapid succession, participants often fail to detect a second salient target, a phenomenon referred as the attentional blink (AB; Raymond, Shapiro, & Arnell, 1992; Shapiro, Raymond, & Arnell, 1997). On the basis of a vast corpus of experiments, several cognitive theories suggest that the blink results from a discrete structuring of attention, sampling information from temporal episodes during which several items can access encoding process (Wyble, Bowman, & Nieuwenstein, 2009; Wyble, Potter, Bowman, & Nieuwenstein, 2011). The objective of this work is to explore the AB when multiple items are presented at the fovea during ocular movements. The authors reasoned that each fixation may cohesively form an episode and hence expected that the blink may vanish within a single fixation. In turn, they expected saccades to accentuate episodic borders and hence shorten the regime of interference when 2 targets are presented fovealy in successive fixations. Evidence is provided in favor of this hypothesis, showing that the blink vanishes when both targets are presented in the core of a single fixation (far from the saccadic boundaries) and that it recovers more rapidly in successive fixations. These studies support current views that episodes should have an effect on the AB and provide evidence that eye movements play an important role in the formation of episodes.     

Are the pathogens of out-groups really more dangerous?

We question the plausibility of Fincher & Thornhill's (F&T's) argument that localised pathogen-host coevolution leads to out-groups having pathogens more damaging than those infecting one's own family or religious group.     

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.     

Effects of category label activation about the elderly

The present research focuses on the study of behavioral effects of non-conscious activation of categories among outgroup (young people) and ingroup members (elderly people). Specifically, non-conscious activation of labels that designate the same group, but with different valence (old vs. elderly), showed an effect on a behavior not directly related to interaction with elderly. The first study with young individuals (N= 62) shows that, after non-conscious activation of a negative label (old), participants displayed longer RTs in the first phase of the task than in the case of positive label (elderly) priming. The second study (N= 40), performed with elderly people, shows a similar result, after non-conscious activation of a negative label (old), elderly people showed longer RTs in the first phase of the task, compared with the group in the non-conscious positive label activation condition. Results concerning the theoretical and practical implications are discussed.     

Parenting style in Spanish parents with children aged 6 to 14

The aim of this paper was to establish which parenting style of Spanish families is associated with optimum children's outcomes. A random Spanish sample of 1,103 parents of children and teenagers from 6 to 14 years of age, of whom 47% were females, reported on their child-rearing practices. Families were classified into 1 of 4 groups (authoritative, authoritarian, indulgent, or neglectful) based on the parents' answers. Socialization outcomes were 6 indicators of interpersonal relationship quality, 9 indicators of psychological adjustment, 7 indicators of personal competence, and 12 indicators of behavior problems. Results showed that indulgent and authoritative parenting styles were associated with better outcomes than authoritarian and neglectful parenting. Overall, our results supported the idea that, in Spain, the optimum parenting style is the indulgent one, as scores in the four sets of socialization outcomes among children and teenagers from indulgent families were always equal to, or even better than, the authoritative parenting style.     

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.     

Influence of perceived social support and functioning on the quality of life of patients with schizophrenia and their caregivers

Perception of social support and functioning of patients with schizophrenia and their primary caregivers and its relationship to quality of life are described. Forty-five patients and their 45 relatives, treated at the Mental Health Services in Arica, Chile, participated. Both patients and caregivers in the study have a poor perception of social support with regard to extra-family people, as well as a low social integration. However, patients showed adequate capacity to function within their immediate family. Unlike what was found in developed countries, these patients showed moderate levels of quality of life, with a strong relationship with perceptions of the social support they receive from family and significant others and the ability to establish and maintain social contacts. Quality of life of primary caregivers is linked to patients' ability to establish and maintain social contacts within the family group, as in other social instances, such as keeping a job. The results of the study suggest the need to consider the design and application of programs of support for these patients and their caregivers, with the central aim of the social functioning of the above-mentioned patients and their familiar and community integration.     

Factor models of the Beck Depression Inventory-II. Validation with coronary patients and a critique of Ward's model

The objective of this study was to validate in a sample of 205 coronary patients a factor model for the BDI-II, especially a model that would allow for modeling of depressive symptoms after explicitly removing bias related to somatic symptoms of depression that would overlap those of heart disease. Exploratory and confirmatory factor analyses for ordinal data were conducted. A one-factor model, six correlated two-factor models and, derivatives thereof, seven models with a single General Depression factor and two uncorrelated factors, were analyzed. Exploratory analysis extracted two factors, Somatic-affective and Cognitive. Confirmatory factor analyses showed the worst fit for the one-factor model. Two-factor models were surpassed in goodness of fit by the models of general-factor and group factors. Among these, the General, Somatic-affective and Cognitive (G-Sa-C) model of Beck with students is noteworthy. The reduced General, Somatic and Cognitive (G-S-C) model of Ward showed the worst goodness of fit. Our model surpasses the cutoff criteria of all fit indexes. We conclude that the inclusion of a general-factor and group factors in all the models surpasses the results of G-S-C model and, therefore, questions it. The G-Sa-C model is strengthened.     

Developmental pattern of digit span in Spanish population

This study examined in a Spanish population the developmental pattern of digit span, as an index of one of the components of Baddeley's working memory--the phonological loop. A verbal digit span was administered to 570 participants ranging from 5 to 17 years old. The results indicated that the digit memory span increases until age 17 as opposed to Anglo-Saxon data--where it is established that this span reaches a peak by age 15. Additionally, these results were compared to the performance in the same task of healthy elderly, Alzheimer disease patients, and Frontotemporal dementia patients, examined in a previous study. The analysis shows that the phonological loop is affected by age and not so much by dementias.
