For decades, psychological research has heavily favored quantitative over qualitative methods. One reason for this imbalance is the perception that quantitative methods follow from a post-positivist paradigm, which guides mainstream psychology, whereas qualitative methods follow from a constructivist paradigm. However, methods and paradigms are independent, and embracing qualitative methods within mainstream psychology is one way of addressing the generalizability crisis.

We welcome Blair's argument that the relationship between fluid cognition and other aspects of intelligence should be an important focus of research, but are less convinced by his arguments that fluid intelligence is dissociable from general intelligence. This is due to confusions between (a) crystallized skills and g, and (b) universal and differential constructs. (Published Online April 5 2006).

Human microbiome research makes causal connections between entire microbial communities and a wide array of traits that range from physiological diseases to psychological states. To evaluate these causal claims, we first examine a well-known single-microbe causal explanation: of Helicobacter pylori causing ulcers. This apparently straightforward causal explanation is not so simple, however. It does not achieve a key explanatory standard in microbiology, of Koch’s postulates, which rely on manipulations of single-microorganism cultures to infer causal relationships to disease. When Koch’s postulates (...) are framed by an interventionist causal framework, it is clearer what the H. pylori explanation achieves and where its explanatory strengths lie. After assessing this ‘simple’, single-microbe case, we apply the interventionist framework to two key areas of microbiome research, in which obesity and mental health states are purportedly explained by microbiomes. Despite the experimental data available, interventionist criteria for explanation show that many of the causal claims generated by microbiome research are weak or misleading. We focus on the stability, specificity and proportionality of proposed microbiome causal explanations, and evaluate how effectively these dimensions of causal explanation are achieved in some promising avenues of research. We suggest some conceptual and explanatory strategies to improve how causal claims about microbiomes are made. (shrink)

The present volume is, we believe, the first-ever edited volume devoted to the emotion of disgust. In this chapter we address the following issues: 1. Why was disgust almost completely ignored until about 1990, 2. Why has there been a great increase in attention to disgust since about 1990?, 3. The outline of an integrative, body-to-soul preadaptation theory of disgust, 4. Some specific features of disgust that make it particularly susceptible to laboratory research and particularly appropriate to address some fundamental (...) issues in psychology. In the final section, we outline some new questions that arise from the recent increased interest in disgust in the areas of brain mechanisms, psychopathology, the psychometric approach to the structure of disgust, and disgust and morality. We then indicate some important aspects of disgust that have yet to receive systematic investigation. (shrink)

The cognitive science of religions’ By-Product Theory contends that much religious thought and behavior can be explained in terms of the cultural activation of maturationally natural cognitive systems. Those systems address fundamental problems of human survival, encompassing such capacities as hazard precautions, agency detection, language processing, and theory of mind. Across cultures they typically arise effortlessly and unconsciously during early childhood. They are not taught and appear independent of general intelligence. Theory of mind undergirds an instantaneous and automatic intuitive understanding (...) of minds, mental representations, and their implications for agents’ actions. By-Product theorists hypothesize about a social cognition content bias, holding that mentalizing capacities inform participants’ implicit understanding of religious representations of agents with counter-intuitive properties. That hypothesis, in combination with Baron-Cohen’s account of Autistic Spectrum Disorder in terms of diminished theory of mind capacities, suggests an impaired religious understanding hypothesis. It proposes that people with ASD have substantial limitations in intuitive understanding of and creative inferences from such representations. Norenzayan argues for a mind-blind atheism hypothesis, which asserts that the truth of these first two hypotheses suggests that people with ASD have an increased probability, compared to the general population, of being atheists. Numerous empirical studies have explored these three hypotheses’ merits. After carefully pondering distinctions between intuitive versus reflective mentalizing and between explicit versus implicit measures and affective versus cognitive measures of mentalizing, the available empirical evidence provides substantial support for the first two hypotheses and non-trivial support for the third.

Gratitude has been promoted as a beneficial emotional experience. However, gratitude is not universally experienced as positive. The current work examines whether an autonomous interpersonal style is associated with differential experience of gratitude. Study 1 found an inverse relationship between trait autonomy and both trait gratitude and positivity of response to receiving a hypothetical benefit from a friend. Study 2 replicated the finding that those higher in autonomy report less trait gratitude, and also demonstrated an inverse relationship between autonomy and (...) valuing gratitude. Study 3 found that those higher in autonomy had more self-image goals and reduced compassionate goals in relationships, and that valuing gratitude mediated the relationship between autonomy and relationship goals. These results show a consistent inverse relationship between autonomy and the experience and valuing of gratitude, suggesting that degree of autonomy is one determinant of whether gratitude is experienced as positive.

A geographically stratified cross-sectional survey was conducted in 2002 to investigate household-level factors associated with use of mosquito control measures and self-reported malaria in Malindi, Kenya. A total of 629 households were surveyed. Logistic regressions were used to analyse the data. Half of all households (51%) reported all occupants using an insecticide-treated bed net and at least one additional mosquito control measure such as insecticides or removal of standing water. Forty-nine per cent reported a history of malaria in the household. (...) Of the thirteen household factors analysed, low (OR=0·23, CI 0·11, 0·48) and medium (OR=0·50, CI 0·29, 0·86) education, mudcoral (OR=0·0·39, CI 0·24, 0·66) and mud block–plaster (OR=0·47, CI 0·25, 0·87) wall types, farming (OR=1·38, CI 1·01, 1·90) and travel to rural areas (OR=0·48, CI 0·26, 0·91) were significantly associated with the use of mosquito control, while controlling for other covariates in the model. History of reported malaria was not associated with the use of mosquito control (OR=1·22, CI 0·79, 1·88). Of the thirteen covariates analysed in the second model, only two household factors were associated with history of malaria: being located in the well-drained stratum (OR=0·49, CI 0·26, 0·96) and being bitten while in the house (OR=1·22, CI 0·19, 0·49). These results suggest that high socioeconomic status is associated with increased household-level mosquito control use, although household-level control may not be enough, as many people are exposed to biting mosquitoes while away from the house and in areas that are more likely to harbour mosquitoes.

           No one owns 'culture'[i]: anyone with a viable theoretical proposal can contend for the right to determine that concept's fate. Not everyone agrees with this view. Throughout its century-long struggle for academic respectability, anthropology has regularly insisted on its unique role as the proprietor of 'culture.' Its variety of approaches and feuding factions notwithstanding, it is this proprietary claim that unifies anthropology to an extent sometimes unrecognized even by its (...) own (post-modernist) practitioners. The history of anthropology has witnessed at least three important moments in the case for autonomous cultural phenomena based, first, on traditional ontological and methodological presumptions, second, on the hermeneutic turn, and third, on postmodern analyses of discourses and their influences.            Historically, anthropologists cite two closely related bases for these proprietary presumptions. The first, which we shall not belabor here, hearkens to inevitably vague discussions about culture's autonomy (with various passes at making sense of the ontological foundations of that alleged autonomy). Cultural anthropologists have advanced such claims for a century, but Geertz' gloss on this topic is representative both in what it endorses and in the vagueness of the grounds for the endorsement. While advancing a host of claims about culture's ontological status (for example, (1) that culture is "ideational," (2) that it, nonetheless, "does not exist in someone's head," (3) that it has the same status--whatever that is--as a Beethoven quartet, and (4) that it is "public"), Geertz insists that "the thing to ask . . . is not what . . . [its] ontological status is." (Geertz 1973: 10-12.) Unfortunately for Geertz and cultural anthropology generally, any convincing case for the autonomy of culture must account for its relations to the things that constitute it. Moreover, because Geertz never relinquishes anthropology's scientific aspirations, the issue of....

One variety of love is familiar in everyday life and qualifies in every reasonable sense as a reactive attitude. ‘Reactive love’ is paradigmatically (a) an affectionate attachment to another person, (b) appropriately felt as a non-self-interested response to particular kinds of morally laudable features of character expressed by the loved one in interaction with the lover, and (c) paradigmatically manifested in certain kinds of acts of goodwill and characteristic affective, desiderative and other motivational responses (including other-regarding concern and a desire (...) to be with the beloved). ‘Virtues of intimacy’ as expressed in interaction with the lover are agent-relative reasons for reactive love, and like other reactive attitudes, reactive love generates reasons in its own right. Within a broad conception of the virtues, reactive love sheds light on the reactive attitudes more generally. (shrink)

Elite athletes, coaches and high-performance staff are exposed to a range of stressors that have been shown to increase their susceptibility to experiencing mental ill-health. Despite this, athletes may be less inclined than the general population to seek support for their mental health due to stigma, perceptions of limited psychological safety within sport to disclose mental health difficulties and/or fears of help-seeking signifying weakness in the context of high performance sport. Guidance on the best ways to promote mental health within (...) sporting environments is increasing, though current frameworks and position statements require greater focus on a whole of system approach, in which the needs of athlete, coaches and high-performance staff are considered within the context of the broader ecological system in which they operate and perform. This paper synthesizes existing research, reviewed for translatability by mental health professionals working in elite sport, to provide an evidence-informed framework with real world utility to promote mentally healthy environments for all stakeholders in elite sporting organizations, from athletes through to administrators. Recommendations are provided to positively impact the mental wellbeing of athletes and support staff, which may in turn influence athletic performance. This framework is intended to provide sporting organizations with evidence-informed or best practice principles on which they can develop or progress their policies to support mental health promotion and prevent the onset of mental health difficulties. It is intended that the framework can be adapted or tailored by elite sporting organizations based upon their unique cultural, contextual and resourcing circumstances. (shrink)

Introduction: Schools have become a primary setting for providing mental health care to youths in the U.S. School-based interventions have proliferated, but their effects on mental health and academic outcomes remain understudied. In this study we will implement and evaluate the effects of a flexible multidiagnostic treatment called Modular Approach to Therapy for Children with Anxiety, Depression, Trauma, or Conduct Problems on students' mental health and academic outcomes.Methods and Analysis: This is an assessor-blind randomized controlled effectiveness trial conducted across five (...) school districts. School clinicians are randomized to either MATCH or usual care treatment conditions. The target sample includes 168 youths referred for mental health services and presenting with elevated symptoms of anxiety, depression, trauma, and/or conduct problems. Clinicians randomly assigned to MATCH or UC treat the youths who are assigned to them through normal school referral procedures. The project will evaluate the effectiveness of MATCH compared to UC on youths' mental health and school related outcomes and assess whether changes in school outcomes are mediated by changes in youth mental health.Ethics and Dissemination: This study was approved by the Harvard University Institutional Review Board. We plan to publish the findings in peer-reviewed journals and present them at academic conferences.Clinical Trial Registration:ClinicalTrials.gov ID: NCT02877875. Registered on August 24, 2016.

© 2017. The American Astronomical Society. All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)
