Organizational patterns in problem solving among Mayan fathers and children

This study examined the social organization of Guatemalan Mayan fathers' engagement with school-age children in a group problem-solving task. Twenty-nine groups of Mayan fathers varying in extent of Western schooling and 3 related school-age children (ages 6-12 years) constructed a puzzle together. Groups with fathers with 0 to 3 grades more often constructed the puzzle through shared multiparty collaboration involving a common agenda, whereas groups with fathers with 12 or more grades more often structured their contributions through a division of labor. Groups involving fathers with 6 to 9 grades demonstrated patterns of coordination that fell between the other two types of schooling groups. Fathers with greater schooling were also found to propose more explicit division-of-labor plans to children than were fathers with no to little schooling. The results indicate that Western schooling may be gradually transforming the collaborative social organization of group problem solving of indigenous Mayan families.     

Multiple Kernel Contraction

This paper focuses on the extension of AGM that allows change for a belief base by a set of sentences instead of a single sentence. In [FH94], Fuhrmann and Hansson presented an axiomatic for Multiple Contraction and a construction based on the AGM Partial Meet Contraction. We propose for their model another way to construct functions: Multiple Kernel Contraction, that is a modification of Kernel Contraction, proposed by Hansson [Han94] to construct classical AGM contractions and belief base contractions. This construction works out the unsolved problem pointed out by Hansson in [Han99, pp. 369]. This revised version was published online in August 2006 with corrections to the Cover Date.     

Just how stable are stable aesthetic features? Symmetry,complexity, and the jaws of massive familiarization

Using both group- and individual-level analyses, we explored the complex and dynamic effects of basic visual features on aesthetic judgment. Specifically, the mediating influence of familiarization on the combined effects of complexity and symmetry on aesthetic judgment was examined. Experiment 1 showed that symmetry and complexity are indeed powerful determinants of aesthetic judgment. Experiment 2 demonstrated that massive familiarization generated contrast effects for complexity: participants familiarized to simple stimuli subsequently judged complex stimuli more beautiful and participants familiarized to complex stimuli subsequently judged simple stimuli more beautiful. In contrast, moderate familiarization in Experiment 3 did not elicit the above effects. Group-level analyses were augmented with judgment analyses of individual response patterns resulting in a more comprehensive assessment of aesthetic judgment.     

Tolerant, Classical, Strict

In this paper we investigate a semantics for first-order logic originally proposed by R. van Rooij to account for the idea that vague predicates are tolerant, that is, for the principle that if x is P, then y should be P whenever y is similar enough to x. The semantics, which makes use of indifference relations to model similarity, rests on the interaction of three notions of truth: the classical notion, and two dual notions simultaneously defined in terms of it, which we call tolerant truth and strict truth. We characterize the space of consequence relations definable in terms of those and discuss the kind of solution this gives to the sorites paradox. We discuss some applications of the framework to the pragmatics and psycholinguistics of vague predicates, in particular regarding judgments about borderline cases.     

Emotional intelligence as predictor of mental, social, and physical health in university students

This study examined the association between emotional intelligence (EI), anxiety, depression, and mental, social, and physical health in university students. The sample was made up of 184 university students (38 men and 146 women). El was evaluated by the Trait Meta-Mood Scale (Salovey, Mayer, Goldman, Turvey, and Palfai, 1995), which evaluates the three dimensions (Attention, Clarity, and Mood Repair). Anxiety was evaluated with the Trait Anxiety Questionnaire (Spielberger, Gorsuch, Lushene, Vagg, and Jacobs, 1983) and depression with the Beck Depression Inventory (Beck, Rush, Shaw, and Emery, 1979). Mental, social, and physical health were evaluated with the SF-12 Health Survey (Ware, Kosinski, and Keller, 1996). Results showed that high Emotional Attention was positively and significantly related to high anxiety, depression, and to low levels of Role Emotional, Social Functioning, and Mental Health. However, high levels of emotional Clarity and Mood Repair were related to low levels of anxiety and depression, high Role Physical, Social Functioning, Mental Health, Vitality, and General Health. This study confirmed the predictive value of Attention, Clarity and Mood Repair regarding the levels of anxiety, depression, and areas related to mental, social, and physical health in university students.     

Time and order effects on causal learning

Five experiments were conducted to explore trial order and retention interval effects upon causal predictive judgments. Experiment 1 found that participants show a strong effect of trial order when a stimulus was sequentially paired with two different outcomes compared to a condition where both outcomes were presented intermixed. Experiment 2 found that a 48-h retention interval eliminates the trial order effect, so that participants gave a global judgment about the relationship between the stimulus and the two outcomes equivalent to the one given by participants that received the two phases intermixed. This result was replicated in Experiment 3 in a situation in which the probability of the outcome in the presence of the cue was changed from .5 for both outcomes (Experiments 1, 2, 4, and 5) to .75 and .25 for outcomes 1 and 2, respectively. Experiment 4 found that retention intervals ranging from 45 min to 48 h eliminated the trial order effect similarly. Experiment 5 found that a 10-min retention interval replicated the effect of time upon sequential training found in precedent experiments, regardless of whether participants remained within the laboratory during the retention interval or spent it outside. The combined results of this experimental series suggest that retention intervals reduce retroactive interference in causal learning by allowing participants to use all the information presented across phases, rather than differentially increasing or decreasing retrieval of information about each of them.     

Spanish adaptation of the Need for Closure Scale

The Need for Cognitive Closure (NCC) refers to the motivation to seek and maintain a definitive answer to a given problem. This mental closure allows people to avoid confusion, ambiguity and uncertainty. The NCC plays a critical role in a variety of processes of diverse nature, including intra-personal (e.g., the higher the NCC, the less generation of hypothesis), inter-personal (e.g., decreased empathy), intra-group (e.g., increased desire for consensus), and inter-group (increased in-group favouritism) phenomena. The goal of the present research was to provide a Spanish adaptation of Antonio Pierro and Arie Kruglanski's Revised NCC Scale (2005, Rev NfCS), examining the reliability and the validity of participants' scores. In the present studies, it was found that the Spanish version of the scale had acceptable internal reliability and adequate factor structure (Study 1), as well as acceptable test-retest reliability and adequate discriminant validity with regard to the scores in another measure of individual differences such as the Need for Cognition (NC, Study 2).     

The taken-for-granted world: A study of the relationship between A. Schutz and J. Ortega y Gassed

This paper is a comparative study of Alfred Schutz and Jose Ortega y Gasset, with special attention to their respective characterization of social reality. For this purpose, the author draws on the explicit references Schutz and Ortega directed towards one another and develops a critical comparison of their theoretical systems. In addition to the reciprocal references which appear in their published works, valuable documentary evidence is provided by Schutz's letters and, first and foremost, by his marginal notes preserved in his own copy of Ortega y Gasset's Man and People. As far as the critical comparison of Schutz's and Ortega's theories is concerned, the weight of the discussion falls on Ortega's Man and People. A careful reading of this essay allows us to successively invoke the key components of Schutz's phenomenological characterization of the structures of the life-world. According to this strategy, and after some preliminary sections devoted to contextual, biographical, and sociocultural matters, the following topics are comparatively discussed: (1) the philosophical foundations of sociology, with particular attention to Ortega's doctrine of the Other as potential danger; (2) the taken-for-granted dimensions of the social world; (3) the multiple spheres of reality, and their structuration around the fundamental core of the radical reality of the I (for Ortega) or the paramount reality of everyday life, as the intersubjective world of culture (for Schutz); (4) the influence of pragmatism on their theoretical systems; (5) their strikingly similar characterization of the perspectivist stratification of the social world; (6) the inexhaustible complexity of the problem of intersubjectivity. Obviously, the common influence of Husserl, Weber, Scheler, and Bergson casts light upon the comparative consideration of any of these issues.     

Mood Regulation Skill and the Symptoms of Endogenous and Hopelessness Depression in Spanish High School Students

To assess the construct validity of the endogenous subtype of depression, 2 studies examined the relation of mood regulation skill to the symptoms of endogenous depression versus hopelessness depression in adolescent samples. It was hypothesized that the relationship between mood regulation skill and endogenous depression would be weaker than the relationship between mood regulation skill and hopelessness depression, because endogenous depression may be less influenced by personality variables, such as mood regulation skill. In spite of the high degree of correlation between the symptoms of hopelessness depression and endogenous depression, the relationship between mood regulation skill and hopelessness depression was stronger than the relationship between mood regulation skill and endogenous depression, as predicted. This is consistent with proposed definition of endogenous depression.     

Thermal sensitivity and cardiovascular reactivity to stress in healthy males

This paper examines the association of cardiovascular reactivity with thermal thresholds (detection and unpleasantness). Heart period (HP), systolic (SBP) and diastolic (DBP) blood pressure of 42 health young males were recorded during a cardiovascular reactivity task (a videogame based upon Sidman's avoidance paradigm). Thermal sensitivity, assessing detection and unpleasantness thresholds with radiant heat in the forearm was also estimated for participants. Participants with differential scores in the cardiovascular variables from base line to task > or = P65 were considered as reactors and those how have differential scores < or = P35 were considered as non-reactors. Significant differences were observed between groups in the unpleasantness thresholds in blood pressure (BP) but not in HP. Reactors exhibited significant higher unpleasantness thresholds than non-reactors. No significant differences were obtained in detection thresholds between groups.
