Conflict tasks and the diffusion framework: Insight in model constraints based on psychological laws

Formal models of decision-making have traditionally focused on simple, two-choice perceptual decisions. To date, one of the most influential account of this process is Ratcliff’s drift diffusion model (DDM). However, the extension of the model to more complex decisions is not straightforward. In particular, conflicting situations, such as the Eriksen, Stroop, or Simon tasks, require control mechanisms that shield the cognitive system against distracting information. We adopted a novel strategy to constrain response time (RT) models by concurrently investigating two well-known empirical laws in conflict tasks, both at experimental and modeling levels. The two laws, predicted by the DDM, describe the relationship between mean RT and (i) target intensity (Piéron’s law), (ii) standard deviation of RT (Wagenmakers–Brown’s law). Pioneering work has shown that Piéron’s law holds in the Stroop task, and has highlighted an additive relationship between target intensity and compatibility. We found similar results in both Eriksen and Simon tasks. Compatibility also violated Wagenmakers–Brown’s law in a very similar and particular fashion in the two tasks, suggesting a common model framework. To investigate the nature of this commonality, predictions of two recent extensions of the DDM that incorporate selective attention mechanisms were simulated and compared to the experimental results. Both models predict Piéron’s law and the violation of Wagenmakers–Brown’s law by compatibility. Fits of the models to the RT distributions and accuracy data allowed us to further reveal their relative strengths and deficiencies. Combining experimental and computational results, this study sets the groundwork for a unified model of decision-making in conflicting environments.     

Religion–state relations and public opinion: norms,institutions and social consensus

ABSTRACT

Are levels of religion–state regulation associated with cross-national variation in attitudes related to the place of religion in public life? Data sources measuring both the institutional relationship between religion and state and public opinion on the political role of religion have significantly improved in recent years, but scholars have just begun to examine relationships between political institutions and public attitudes. This contribution tests several potential examples of such links by exploring the relationship between religion–state institutions and norms of religion and politics, both between and within countries. The contribution first develops theoretical expectations regarding the institutional correlates of public opinion, then conducts initial tests of these expectations by blending data from the Religion and State project with comparative survey data drawn from Waves 4 and 5 of the World Values Survey. Analysis demonstrates modest links between institutions and aggregate public views, a relationship between institutions and social consensus, and, most robustly, consistent variation in institutional effects across political regime type.     

Construct validity of global life-satisfaction judgments: A look into the black box of self–informant agreement

Life-satisfaction judgments are ubiquitously used as indicators of wellbeing. The construct validity of these judgments relies heavily on self–informant agreement. However, agreement is necessary, but not sufficient to claim that life-satisfaction judgments are valid. In addition, self–informant agreement should be based on the use of valid information about satisfaction with important life domains. An alternative possibility is that agreement is based on impressions about personality traits. We tested these two hypotheses in a model that predicted self-ratings and informant ratings of life satisfaction from shared perceptions of personality and satisfaction with life domains. In a round-robin study of families, we found that life-domains were the key predictor of self–informant agreement. However, the Depressiveness facet of Neuroticism had a small direct effect. In addition, it was indirectly related to self–informant agreement because it predicts lower satisfaction in important life-domains that were used to form life-satisfaction judgments.     

Taiwanese speech–language therapists’ awareness and experiences of service provision to transgender clients

Background: One of the most influential factors that affect the quality of life of transgender individuals is whether they can be perceived by others to “pass” in their felt gender. Voice and communication style are two important identifying dimensions of gender and many transgender individuals wish to acquire a voice that matches their gender. Evidence shows that few transgender individuals access voice therapy, and that this is caused by their concerns about stigmatization or negative past experiences within healthcare services. In order to address the negative experiences faced by transgender populations we need a better understanding of healthcare services’ current levels of knowledge and LGBT awareness. Some studies of Speech–Language Therapists’ (SLTs’) experience and confidence working with transgender individuals have recently been undertaken in the United States (US). However, little research has been carried out in Asia.

Aims: To investigate Taiwanese SLTs’ knowledge, attitudes and experiences of providing transgender individuals with relevant therapy.

Method: A cross-sectional self-administered web-based survey hosted on the Qualtrics platform was delivered to 140 Taiwanese SLTs.

Results: Taiwanese SLTs were, (i) more familiar with the terminology used to address “lesbian, gay, and bisexual groups” than with “transgender” terminology, (ii) generally positive in their attitudes toward transgender individuals, and (iii) comfortable about providing clinical services to transgender clients. However, the majority of participants did not feel that they were sufficiently skilled in working with transgender individuals, even though most believed that providing them with voice and communication services fell within the SLT scope of practice.

Conclusion: It is important for clinicians to both be skilled in transgender voice and communication therapy and to be culturally competent when providing services to transgender individuals. This study recommends that cultural competence relating to gender and sexual minority groups should be addressed in SLTs’ university education as well as in their continuing educational programs.     

Gift narration: dynamic themes of reciprocity,debt, and social relations in Theravāda Buddhist Myanmar

ABSTRACT

Scholarly studies of Buddhist gift-giving have explored the many ways in which gifts are or are not reciprocal. This topic is revisited in this article by the author drawing greater attention to the practice of narration. Instead of understanding Buddhist words about dāna as representing religious doctrines or the experience of its social practice, the author considers how Buddhists narrate dāna as a means of maintaining relationships with self and others. Examining narratives of one monastic gift-recipient, meanings of dāna and moral principles of gift-giving are shown to vary alongside shifting relations between givers and receivers. This case suggests that themes of reciprocity are most salient when narrators grapple with interpersonal threats. Offering possible interpretations of this correlation, the author argues how reciprocal forces could be external social conditions to which narratives respond as well as created ex nihilo through the practice of narration as a strategy of ordering interpersonal conflicts potentially unrelated to reciprocity.     

What happened in kindergarten? Mother-child conversations about life story chapters

ABSTRACT

Research indicates that adults form life story chapters, representations of extended time periods that include people, places and activities. Life chapter memories are distinct from episodic memories and have implications for behaviour, self and mental health, yet little is known about their development during childhood. Two exploratory studies examined parent–child conversations about life chapters. In Study 1, mothers recorded naturalistic conversations with their 5–6 year old children about two chapters in the child’s life. In Study 2, mothers recorded conversations with their 6–7 year old children about a particular life chapter—the child’s kindergarten year—and also about a specific episode of their choice. The results indicated that young children are able to recall and discuss information about life chapters and that parents actively scaffold children’s discussion of general information in chapters as well as specific events. Mothers’ conversational style when discussing chapters (e.g., elaborativeness) predicted children’s memory contributions, and was also positively correlated with their style when discussing specific events. The results suggest new avenues for research on the ontogeny of life chapters, the factors that shape them, and their role in development.     

Effectiveness of the Visual–Auditory Shadowing Method on Learning the Pronunciation of Kanji

This study investigates whether the visual–auditory (VA) shadowing method can better facilitate vocabulary learning for learners of Japanese as a second language (JSL) than the visual–visual (VV) shadowing method in K-8 immersion education. Learning vocabulary involves three aspects: meaning, orthography, and pronunciation. The Japanese language has complex orthography and pronunciation. Learners of Japanese need to learn three kinds of orthographic characters: ideographs (kanji) and two kinds of syllabic characters (hiragana and katakana). In addition, because the pronunciation of kanji can vary by context, learners must learn several pronunciations for a single kanji character. This study explores a reasonable way to learn pronunciations of kanji and compares VA shadowing (n = 48) and VV shadowing (n = 47) to investigate which condition better facilitates learning the pronunciation of Japanese ideographs. The analysis suggests that compared to the VV shadowing condition (p < .05), the VA shadowing condition is more effective for Level 3 learners but not for Level 2 or Level 1 learners.
