Cognitive-behavioral stress management intervention decreases the prevalence of depression and enhances benefit finding among women under treatment for early-stage breast cancer.

The authors tested effects of a 10-week group cognitive-behavioral stress management intervention among 100 women newly treated for Stage 0-II breast cancer. The intervention reduced prevalence of moderate depression (which remained relatively stable in the control condition) but did not affect other measures of emotional distress. The intervention also increased participants' reports that having breast cancer had made positive contributions to their lives, and it increased generalized optimism. Both remained significantly elevated at a 3-month follow-up of the intervention. Further analysis revealed that the intervention had its greatest impact on these 2 variables among women who were lowest in optimism at baseline. Discussion centers on the importance of examining positive responses to traumatic events--growth, appreciation of life, shift in priorities, and positive affect-as well as negative responses.     

W-algebras which are Boolean products of members of SR[1] and CW-algebras

We show that the class of all isomorphic images of Boolean Products of members of SR [1] is the class of all archimedean W-algebras. We obtain this result from the characterization of W-algebras which are isomorphic images of Boolean Products of CW-algebras.     

Visual attention to own- versus other-race faces: Perspectives from learning mechanisms and task demands

Multiple factors have been proposed to contribute to the other-race effect in face recognition, including perceptual expertise and social-cognitive accounts. Here, we propose to understand the effect and its contributing factors from the perspectives of learning mechanisms that involve joint learning of visual attention strategies and internal representations for faces, which can be modulated by quality of contact with other-race individuals including emotional and motivational factors. Computational simulations of this process will enhance our understanding of interactions among factors and help resolve inconsistent results in the literature. In particular, since learning is driven by task demands, visual attention effects observed in different face-processing tasks, such as passive viewing or recognition, are likely to be task specific (although may be associated) and should be examined and compared separately. When examining visual attention strategies, the use of more data-driven and comprehensive eye movement measures, taking both spatial–temporal pattern and consistency of eye movements into account, can lead to novel discoveries in other-race face processing. The proposed framework and analysis methods may be applied to other tasks of real-life significance such as face emotion recognition, further enhancing our understanding of the relationship between learning and visual cognition.     

Stimulus control of predatory behavior by the Iberian wall lizard (Podarcis hispanica, Sauria, Lacertidae): effects of familiarity with prey

The authors examine the relative roles of vision and chemoreception and the influence of previous experience with prey on the predatory behavior of Iberian wall lizards (Podarcis hispanica). Experiment 1 compared the responses to visual, chemical, and a combination of visual and chemical cues of a familiar prey by 2 groups of lizards that had been kept in captivity for either 3 months or 21 days. Experiment 2 assessed the responses of lizards kept in the laboratory for more than 3 months to a novel prey species. The results reveal that feeding on a prey species affects the lizards' responses to chemical stimuli from that prey. The response to chemical cues of a novel prey requires a 1st-feeding experience with that prey. Lizards that have been fed the same prey species for several months cease responding to the chemical stimuli of that particular prey.     

Eye-movement patterns in face recognition are associated with cognitive decline in older adults

The Hidden Markov Modeling approach for eye-movement data analysis is able to quantitatively assess differences and similarities among individual patterns. Here we applied this approach to examine the relationships between eye-movement patterns in face recognition and age-related cognitive decline. We found that significantly more older than young adults adopted “holistic” patterns, in which most eye fixations landed around the face center, as opposed to “analytic” patterns, in which eye movements switched among the two eyes and the face center. Participants showing analytic patterns had better performance than those with holistic patterns regardless of age. Interestingly, older adults with lower cognitive status (as assessed by the Montreal Cognitive Assessment), particularly in executive and visual attention functioning (as assessed by Tower of London and Trail Making Tests) were associated with a higher likelihood of holistic patterns. This result suggests the possibility of using eye movements as an easily deployable screening assessment for cognitive decline in older adults.     

El innatismo de Fodor: Consideraciones críticas

RESUMEN

En este artículo se analizan algunos de los principales conceptos de la teoría innatista de Fodor: lenguaje del pensamiento, teoría representacional de la mente, conceptos innnatos, modularidad, etc. El propósito de dicho análisis es mostrar las limitaciones de la argumentación innatista de Jerry Fodor, sugiriendo que en ella se demuestra mucho menos de lo que se pretende, además de no permitir una justificación del innatismo de acuerdo con los conceptos de su teoría, antes mencionados. Para ello, se expondrá en primer lugar el argumento central de la teoría funcional innatista de Fodor, mediante un análisis crítico, para después seguir con un esbozo de la noción de aprendizaje conceptual más allá de la dicotomía innato versus aprendido.     

Incidental emotions associated with uncertainty appraisals impair decisions in the Iowa Gambling Task

With the Appraisal Tendency Framework, it has been established that (un)certainty appraisals associated with incidental emotions trigger the kind of information processing to cope with situation. We tested the impact of (un)certainty-associated emotions on a sequential task, the Iowa Gambling Task. In this task, intuitive processing is necessary to lead participants to rely on emotional cues arising from previous decisions and to making advantageous decisions. We predicted that certainty-associated emotions would engage participants in intuitive processing, whereas uncertainty-associated emotions would engage them in deliberative processing and lead them to make disadvantageous decisions. As expected, we observed in two distinct experiments, that participants induced to feel uncertainty (fear, sadness) were found to decide less advantageously than participants induced to feel certainty (anger, happiness, disgust).
