Cognitions associated with initial medical consultations concerning recurrent breathing difficulties: A community-based study

Abstract

A two-stage community survey identified 568 respondents reporting recurrent breathing difficulties over a one-year period. Subsequent interviews allowed comparison of (i) 21 respondents who had never consulted a doctor about frequent wheezing (i.e., on more than 30 days) or serious breathing difficulties (i.e., disrupting everyday activities) over the past year with (ii) a randomly selected group of 22 who had seen their doctor concerning breathing difficulties in the past year. These groups were found to be similar with respect to demographic and lung function measures. An extended health belief model framework including causal attributions for breathing difficulties and consulting self-efficacy was used to explore cognitions which might distinguish between the two groups. Logistic regression suggested that lower perceived relative severity of symptoms (in relation to other problems). attribution of wheezing to smoking and lower self-efficacy in relation to explaining breathing difficulties to a doctor distinguished between those who did and did not consult. Health education implications. including initiatives to encourage medical help-seeking amongst those with recurrent, frequent or serious breathing difficulties are discussed.     

Emotional expressions facilitate human–human trust when using automation in high-risk situations

This study investigated the utility of emotional expression for human decision aids, when human aids conflict with an automated decision support system (DSS). The increasing presence of automation in society has resulted in critical, and often life threatening, situations when information from human and automated sources disagree. It has been known that reliance on human aids decrease during high-risk situations, while reliance on automated aids increase. However, it is also possible that human decision aids gain credibility from users when they embody the charismatic and emotionally expressive gesticulations seen in successful organizational leaders. The present study tested how a human agent's expressiveness when providing information would influence participants' behavioral reliance. Using the program Convoy Leader, participants (n=56) engaged in three decision-making scenarios where risk was manipulated as a within-subject factor and emotional expression as a between-subject factor. Emotional susceptibility, perceived risk, and trust for human as well as automated aids were measured. Overall trust was higher for the automated tool than human decision aid, and that pattern was amplified in conditions without an emotionally expressive human aid. Reliance was greater for emotionally expressive human aids, than stoic human aids, particularly during high risk conditions. The findings suggest that emotional expression of a human aid significantly impacts both reliance and trust of a decision aid, especially at higher risk levels. Emotionally expressive human agents should be utilized in decision conflicts where the automated system has certainly failed.     

Being modest makes you feel bad: Effects of the modesty norm and mortality salience on self‐esteem in a collectivistic culture

Terror management research shows that existential terror motivates people to live up to social norms. According to terror management theory (TMT), people can achieve a sense of self‐worth through compliance with social norms. However, this has not yet been empirically tested. Modesty has long been known as an important social norm in Eastern cultures, such as China, Japan, and Korea. The current research examined whether conforming to the modesty norm in response to reminders of death concerns increases self‐esteem for Chinese. In Study 1, following the modesty norm (i.e., explicit self‐effacement) led to decreased implicit self‐esteem, however, this was only the case if mortality was salient. In Study 2, violating the modesty norm (i.e., explicit self‐enhancement) increased implicit self‐esteem – however – again, this was only the case when mortality was salient. These findings indicate that self‐esteem cannot be maintained through compliance with the modesty norm. Implications of this research for understanding the interplay between self‐esteem and social norms in terror management processes are discussed.     

Individualism and sociocultural adaptation: Discrimination and social capital as moderators among rural‐to‐urban migrants in China

This study examined the associations of sociocultural adaptation with individualism and collectivism and the moderating roles of discrimination and social capital in the associations among rural‐to‐urban migrants (N = 641) in Beijing, China. Results indicated that individualism was associated with poorer adaptation for migrants reporting low perceived discrimination or low social capital. However, migrants reporting high perceived discrimination showed poorer adaptation, regardless of individualism; and migrants reporting high social capital showed better adaptation, regardless of individualism. Collectivism was not related to adaptation. Findings suggest that individualism may be detrimental to migrants’ adjustment to a collectivistic society.     

Shyness and Adaptation to School in a Chinese Community

This study examined the process of adjustment in shy and nonshy children during the transition to school in a Chinese community. Children (35 shy and 19 nonshy) were assessed three times before and after they entered the first grade. Shy and nonshy children's interactions with peers and teachers, perceived peer acceptance, and anxious behaviour were measured using multiple methods, including naturalistic observations, self‐report, and teacher report. Results indicated that shy and nonshy children showed consistently different behavioural profiles in free play settings and structured classes during the transition. However, teacher ratings of and peer responses to shy and nonshy children were not consistently different. Results are discussed in relation to the cultural context where the study was conducted.

Multitasking versus multiplexing: Toward a normative account of limitations in the simultaneous execution of control-demanding behaviors

Why is it that behaviors that rely on control, so striking in their diversity and flexibility, are also subject to such striking limitations? Typically, people cannot engage in more than a few—and usually only a single—control-demanding task at a time. This limitation was a defining element in the earliest conceptualizations of controlled processing; it remains one of the most widely accepted axioms of cognitive psychology, and is even the basis for some laws (e.g., against the use of mobile devices while driving). Remarkably, however, the source of this limitation is still not understood. Here, we examine one potential source of this limitation, in terms of a trade-off between the flexibility and efficiency of representation (“multiplexing”) and the simultaneous engagement of different processing pathways (“multitasking”). We show that even a modest amount of multiplexing rapidly introduces cross-talk among processing pathways, thereby constraining the number that can be productively engaged at once. We propose that, given the large number of advantages of efficient coding, the human brain has favored this over the capacity for multitasking of control-demanding processes.     

基于文本阅读的间接接触也可改善公众对残疾人的态度

以镶嵌残疾人图片的正性行为描述性信息为文本阅读材料,以大学生为被试,采用概念启动范式,考察了健全人对残疾人态度改善的可能性.研究结果表明,阅读残疾人正性行为描述性材料不仅可以降低健全人对残疾人的负性认知评价,而且可以提高其对残疾人的钦佩感和减弱其对残疾人的嫌弃感,同时也可提高健全人对该类人群的积极趋近行为和减弱对该类人群的消极趋近和消极回避行为,从而证明基于文本阅读的间接接触可改善公众对残疾人的负性态度的假设.因此,创造条件鼓励残疾人尽力发挥其积极的社会功能,引导和塑造其身残志不残的品质,有助于改善健全人对该类人群的消极态度.     

Revisiting letter transpositions within and across morphemic boundaries

Early morphological decomposition of complex words has been supported by evidence showing that the magnitude of masked transposed-letter (TL) priming effects is greater for within-morpheme transpositions than for between-morpheme transpositions. However, these findings have lately been called into question, and a recent article by Sánchez-Gutiérrez and Rastle (Psychonomic Bulletin & Review, 20, 988–996, 2013) suggested that the above-mentioned interaction could have been the consequence of a false positive (i.e., a Type I error). Considering recent evidence showing that morpho-orthographic interactions are highly sensitive to individual differences in reading skills, we explored whether participants’ averaged reading speeds were responsible for modulating the size of within- versus between-morpheme TL priming effects. A large-scale lexical decision experiment with a set of 420 suffixed Spanish words (N = 80 participants) was run using the masked-priming technique. The results revealed that individual differences modulated the magnitude of the masked TL priming effect between morphemes: Faster readers (but not slower readers) yielded greater TL priming for within- than for between-morpheme transpositions. The present data help reconcile previous divergent data by showing that faster readers revealed a morpho-orthographic interaction, whereas slower readers may rely more on a morphological-processing strategy that is not sensitive to morpho-orthographic interactions.     

On Pretabular Logics in NExtK4 (Part II)

In this paper we prove the pretabularity criteria for the logics of infinite depth in NExtK4. Then we use the criteria to resolve the problems of pretabular logics in NExtQ4 and prove that there is a continuum of pretabular logics in NExtQ4 just like NExtK4.
