Hide-and-seek around the centre of interest: The dead zone of attention revealed by change blindness

Three experiments examined spatial allocation of attention during active search for visual changes. In all experiments, there were three conditions of change location related to a centre of interest: (1) Central (most attended location itself), (2) near, and (3) far marginal change. In Experiment 1, participants showed the slowest search and the largest number of undetected changes in near condition. Moreover, they misidentified near changes more frequently than central and far ones. In Experiment 2, participants had to search for marginal changes in the presence of a once noticed central change that summoned additional attention to a central location. It resulted in further search slowing for near changes. In Experiment 3, participants searched for one of two concurrent marginal changes in the presence of a central one. They detected far changes about 2.3 times more frequently than near ones. Taken together, these results support the notion of “dead zone of attention” surrounding attentional focus. Several speculations about the nature of dead zone are discussed.     

A randomized clinical trial of Behavioral Activation (BA) therapy for improving psychological and physical health in dementia caregivers: Results of the Pleasant Events Program (PEP)

Dementia caregiving is associated with elevations in depressive symptoms and increased risk for cardiovascular diseases (CVD). This study evaluated the efficacy of the Pleasant Events Program (PEP), a 6-week Behavioral Activation intervention designed to reduce CVD risk and depressive symptoms in caregivers. One hundred dementia family caregivers were randomized to either the 6-week PEP intervention (N = 49) or a time-equivalent Information-Support (IS) control condition (N = 51). Assessments were completed pre- and post-intervention and at 1-year follow-up. Biological assessments included CVD risk markers Interleukin-6 (IL-6) and D-dimer. Psychosocial outcomes included depressive symptoms, positive affect, and negative affect. Participants receiving the PEP intervention had significantly greater reductions in IL-6 (p = .040), depressive symptoms (p = .039), and negative affect (p = .021) from pre- to post-treatment. For IL-6, clinically significant improvement was observed in 20.0% of PEP participants and 6.5% of IS participants. For depressive symptoms, clinically significant improvement was found for 32.7% of PEP vs 11.8% of IS participants. Group differences in change from baseline to 1-year follow-up were non-significant for all outcomes. The PEP program decreased depression and improved a measure of physiological health in older dementia caregivers. Future research should examine the efficacy of PEP for improving other CVD biomarkers and seek to sustain the intervention's effects.     

Parental Attitudes,Attachment Styles,Social Networks,and Psychological Processes in Autism Spectrum Disorders: A Cross-Cultural Perspective

In this study the authors used a cross-cultural approach to examine parental attitudes, attachment styles, social networks, and some of the psychological processes involved in Autism Spectrum Disorders (ASD). Fifty-two children (aged 4–11 years) took part in the study: 30 Italians (15 with ASD and 15 controls) and 22 Cubans (11 with ASD and 11 controls). Findings indicated significant differences between the two cultural groups in terms of the structure of the children's social network and parental attitudes toward their children. However, the mother–child attachment relationship and cognitive and emotional functioning of the study participants were independent of culture.     

Proper bootstrapping

According to a much discussed argument, reliabilism is defective for making knowledge too easy to come by. In a recent paper, Weisberg aims to show that this argument relies on a type of reasoning that is rejectable on independent grounds. We argue that the blanket rejection that Weisberg recommends of this type of reasoning is both unwarranted and unwelcome. Drawing on an older discussion in the philosophy of science, we show that placing some relatively modest restrictions on the said type of reasoning suffices to block the anti-reliabilist argument.     

Kognitive Dissonanz nach Entscheidungen und psychische Erkrankungen

Building upon Grawe’s consistency theory the target of this study was to examine if cognitive dissonance has an influence on mental disorders. More precisely, whether post-decisional cognitive dissonance (1) is more pronounced in patients with mental disorders and (2) whether it correlates with symptom burden. Obsessive-compulsive disorder patients (OCD; n?=?15), depressive patients (n?=?20) and controls (n?=?42) completed a post-decisional cognitive dissonance scale as well as a scale assessing their respective symptom burden. Solely OCD patients showed heightened cognitive dissonance compared to controls (p?=?0.019). Among depressive patients, however, a very high correlation was found to exist between symptom burden and cognitive dissonance (r?=?0.70). Therefore, OCD seems to be related to increased cognitive dissonance which supports the assumption that cognitive dissonance plays a role in this mental disorder.

Gravity is not the only ruler for falling events: Young children stop making the gravity error after receiving additional perceptual information about the tubes mechanism

Young children seem to operate under the assumption that objects always fall in a straight vertical line. When asked to search for a ball dropped down an S-shaped opaque tube, they repeatedly search directly below. Hood proposed that children have difficulty in inhibiting their prepotent expectation that objects fall in a straight line (Hood, 1995). We asked whether the inability to inhibit this prepotent response is the only factor determining children’s performance on the tubes task. In one condition the openings to the tubes were covered by chimneys, whereas in another condition the openings were visible. When first tested with the apparatus, children performed better when the openings were visible. Furthermore, children’s performance on equally complex configurations (i.e., with or without chimneys) was modulated by their previous experience. Thus, children’s understanding of the tubes mechanism seems to play an important role in addition to inhibitory control.     

Intellectuals as missionaries: the liberal opposition in Russia and their notion of culture

The present article is primarily concerned with the imagined community of liberal intellectuals (starting with the Westernizers, in the 1840s, and ending with the Kadets and the participants of the October Revolution in the early twentieth century), rather than the community that “objectively” existed. This imaginary community constructed notions of the collective identity of their own group as well as that of Russian society. For this purpose, they instrumentalized the notions of “progress,” “backwardness,” “culturedness” (kul’turnost’) and “benightedness” (temnota), thereby creating hierarchies in which the “constructors” of collective identities granted themselves the important role of intermediaries between state and society. Special attention is paid to the prominent role Russia’s liberal historians played in this process insofar as historians possessed great power in nineteenth-century Europe—the power to tell their states and societies about their past, present, and future—and this transformed them into professional producers of (national) identities. Their work combined expert knowledge and ideological clichés in a highly complex manner. The central question posed is to what extent and in what respect the reality constructed by Russian intellectuals coincided with the actions of intellectuals in other European regions or, on the contrary, to what extent their discursive activities had a specifically local character.     

The Preface Paradox Revisited

The Preface Paradox has led many philosophers to believe that, if it isassumed that high probability is necessary for rational acceptability, the principleaccording to which rational acceptability is closed under conjunction (CP)must be abandoned. In this paper we argue that the paradox is far less damaging to CP than is generally believed. We describe how, given certain plausibleassumptions, in a large class of cases in which CP seems to lead tocontradiction, it does not do so after all. A restricted version of CP canthus be maintained.
