Accurate and biased perceptions of responsive support predict well-being

The current research examined effects of accurate and biased perceptions of romantic partners’ responsive support provision on perceivers’ well-being. Perceivers discussed a personal problem with their romantic partners (“targets”). Perceivers’ perceptions of targets’ responsive support following the discussion were related to external indicators of targets’ behavior, but these perceptions also were predicted by perceivers’ sentiments toward targets, suggesting that processes underlying perceivers’ perceptions were a blend of both accuracy and bias. In addition, both accurately perceived and biased perceptions of targets’ responsiveness predicted perceivers’ personal well-being (i.e., affect, coping, self-efficacy) and interpersonal well-being (i.e., more positive sentiments toward targets) immediately after the support interaction, 2 weeks later, and 6 months later. Results suggest that accurate and biased cognition during interpersonal interactions can have important consequences for perceivers’ personal and interpersonal well-being through effects on perceived partner responsiveness.     

Quantitative Standards for Absolute Linguistic Universals

Absolute linguistic universals are often justified by cross‐linguistic analysis: If all observed languages exhibit a property, the property is taken to be a likely universal, perhaps specified in the cognitive or linguistic systems of language learners and users. In many cases, these patterns are then taken to motivate linguistic theory. Here, we show that cross‐linguistic analysis will very rarely be able to statistically justify absolute, inviolable patterns in language. We formalize two statistical methods—frequentist and Bayesian—and show that in both it is possible to find strict linguistic universals, but that the numbers of independent languages necessary to do so is generally unachievable. This suggests that methods other than typological statistics are necessary to establish absolute properties of human language, and thus that many of the purported universals in linguistics have not received sufficient empirical justification.     

Evidence for a fixed capacity limit in attending multiple locations

A classic question concerns whether humans can attend multiple locations or objects at once. Although it is generally agreed that the answer to this question is “yes,” the limits on this ability are subject to extensive debate. According to one view, attentional resources can be flexibly allocated to a variable number of locations, with an inverse relationship between the number of selected locations and the quality of information processing at each location. Alternatively, these resources might be quantized in a “discrete” fashion that enables concurrent access to a small number of locations. Here, we report a series of experiments comparing these alternatives. In each experiment, we cued participants to attend a variable number of spatial locations and asked them to report the orientation of a single, briefly presented target. In all experiments, participants’ orientation report errors were well-described by a model that assumes a fixed upper limit in the number of locations that can be attended. Conversely, report errors were poorly described by a flexible-resource model that assumes no fixed limit on the number of locations that can be attended. Critically, we showed that these discrete limits were predicted by cue-evoked neural activity elicited before the onset of the target array, suggesting that performance was limited by selection processes that began prior to subsequent encoding and memory storage. Together, these findings constitute novel evidence supporting the hypothesis that human observers can attend only a small number of discrete locations at an instant.     

Frontotemporal neural systems supporting semantic processing in Alzheimer’s disease

We hypothesized that semantic memory for object concepts involves both representations of visual feature knowledge in modality-specific association cortex and heteromodal regions that are important for integrating and organizing this semantic knowledge so that it can be used in a flexible, contextually appropriate manner. We examined this hypothesis in an fMRI study of mild Alzheimer’s disease (AD). Participants were presented with pairs of printed words and asked whether the words matched on a given visual–perceptual feature (e.g., guitar, violin: SHAPE). The stimuli probed natural kinds and manufactured objects, and the judgments involved shape or color. We found activation of bilateral ventral temporal cortex and left dorsolateral prefrontal cortex during semantic judgments, with AD patients showing less activation of these regions than healthy seniors. Moreover, AD patients showed less ventral temporal activation than did healthy seniors for manufactured objects, but not for natural kinds. We also used diffusion-weighted MRI of white matter to examine fractional anisotropy (FA). Patients with AD showed significantly reduced FA in the superior longitudinal fasciculus and inferior frontal-occipital fasciculus, which carry projections linking temporal and frontal regions of this semantic network. Our results are consistent with the hypothesis that semantic memory is supported in part by a large-scale neural network involving modality-specific association cortex, heteromodal association cortex, and projections between these regions. The semantic deficit in AD thus arises from gray matter disease that affects the representation of feature knowledge and processing its content, as well as white matter disease that interrupts the integrated functioning of this large-scale network.     

Corruption as a global hindrance to promoting ethics,integrity, and sustainable development in Tanzania: the role of the anti-corruption agency

Corruption is the single greatest challenge that erodes and defeats efforts made by many nations, especially in the developing world, towards sustainable development and towards the promotion and strengthening of democratic institutions and values. This article lays out international norms of ethics and integrity, reflected also in Tanzanian norms. It argues that strategic decision is imperative and a ‘Good Governance Architecture' is meant to provide a working solution to curb unethical behaviour, corruption, and the culture of impunity. This working solution – which involves economic and institutional reforms, prevention strategies, enforcement, political will, transparency, accountability, popular participation, the rule of law, and the democratic space – goes further towards the root cause of the problem than legal norms do.     

Assessment of perception of morphed facial expressions using the Emotion Recognition Task: Normative data from healthy participants aged 8–75

The ability to recognize and label emotional facial expressions is an important aspect of social cognition. However, existing paradigms to examine this ability present only static facial expressions, suffer from ceiling effects or have limited or no norms. A computerized test, the Emotion Recognition Task (ERT), was developed to overcome these difficulties. In this study, we examined the effects of age, sex, and intellectual ability on emotion perception using the ERT. In this test, emotional facial expressions are presented as morphs gradually expressing one of the six basic emotions from neutral to four levels of intensity (40%, 60%, 80%, and 100%). The task was administered in 373 healthy participants aged 8–75. In children aged 8–17, only small developmental effects were found for the emotions anger and happiness, in contrast to adults who showed age‐related decline on anger, fear, happiness, and sadness. Sex differences were present predominantly in the adult participants. IQ only minimally affected the perception of disgust in the children, while years of education were correlated with all emotions but surprise and disgust in the adult participants. A regression‐based approach was adopted to present age‐ and education‐ or IQ‐adjusted normative data for use in clinical practice. Previous studies using the ERT have demonstrated selective impairments on specific emotions in a variety of psychiatric, neurologic, or neurodegenerative patient groups, making the ERT a valuable addition to existing paradigms for the assessment of emotion perception.     

Catholicism,Protestantism, and Mexicanness on the US–Mexico border: discourses,narrative identities,habits, and affect

ABSTRACT

In Mexico, Catholicism and national identity are deeply intertwined through what we call a process of articulation. Thus, not surprisingly, despite the recent impressive growth of Protestantism in the nation, most people still believe that being Mexican and being Catholic are almost synonymous. Additionally, because the two identifications do not ‘cross each other’ (as the metaphor of intersectionality posits) but, instead, enter a very complex process of articulation in which each modifies the other, there is a particular way in which many Mexicans experience and perform their Catholicism, in the same vein that there is a particular way in which Catholics experience and perform their Mexicanness. Simultaneously, because neither nationality nor religion is narrated and/or performed in isolation to other forms of identification (e.g. race, ethnicity, region, gender) other possible identifications are also articulated or co-inform (in different ways) nationality and religion in the identitarian encounters that occur on the border. In the way people build their identifications around religion, narratives, practices, habits, affect, and emotions are continuously interrelated. We show that having an altar outside one’s house or making the sign of the cross on one’s body is both (depending on the unfolding of the social interactions and their patterns of relations) a non-linguistic discourse and a habit. We also show that their mere presence (in the case of altars) or performance (in the case of the sign of the cross) affect the people around the site or the performance, triggering complex emotions. That altar and sign of the cross can potentially be all these things simultaneously highlights their importance as ‘affective conductors’—stressing their significance as central objects in the intensification of relations that give new capacities to the entities involved in the patterns of relationship at play in the identitarian encounter at stake.
