Adaptationism--how to carry out an exaptationist program

Adaptationism is a research strategy that seeks to identify adaptations and the specific selective forces that drove their evolution in past environments. Since the mid-1970s, paleontologist Stephen J. Gould and geneticist Richard Lewontin have been critical of adaptationism, especially as applied toward understanding human behavior and cognition. Perhaps the most prominent criticism they made was that adaptationist explanations were analogous to Rudyard Kipling's Just So Stories (outlandish explanations for questions such as how the elephant got its trunk). Since storytelling (through the generation of hypotheses and the making of inferences) is an inherent part of science, the criticism refers to the acceptance of stories without sufficient empirical evidence. In particular, Gould, Lewontin, and their colleagues argue that adaptationists often use inappropriate evidentiary standards for identifying adaptations and their functions, and that they often fail to consider alternative hypotheses to adaptation. Playing prominently in both of these criticisms are the concepts of constraint, spandrel, and exaptation. In this article we discuss the standards of evidence that could be used to identify adaptations and when and how they may be appropriately used. Moreover, building an empirical case that certain features of a trait are best explained by exaptation, spandrel, or constraint requires demonstrating that the trait's features cannot be better accounted for by adaptationist hypotheses. Thus, we argue that the testing of alternatives requires the consideration, testing, and systematic rejection of adaptationist hypotheses. Where possible, we illustrate our points with examples taken from human behavior and cognition.     

4～6岁儿童三种时间副词理解能力及策略的实验研究

采用定量与定性相结合的研究方法,对4～6岁儿童理解时间副词的能力进行了初步的探查,结果表明:(1)学前儿童对不同时间副词的理解能力是不同的。对现在时间副词的理解优于对过去时间副词的理解,对将来时间副词的理解能力最低,基本处于萌芽阶段。但这种理解能力的年龄发展效应不明显。(2)在表示将来的时间副词中,儿童对不同的具体时间副词表现出认知差异。(3)学前儿童在理解时间副词时多种策略并存。随着年龄的增长,有效策略的生成能力有了明显的提高。     

The crucial roles of stimulus matching and stimulus identity in negative priming

Negative priming refers to the situation in which an ignored item on an initial prime trial suffers slowed responding when it becomes the target item on a subsequent probe trial. In this experiment (and a replication), we demonstrate two ways in which stimulus consistency (matching) governs negative priming. First, negative priming for identical words occurred only when the prime distractor changed color when it became the probe target (i.e., constant cue to read the red word); negative priming disappeared when the prime distractor retained its color as the probe target (i.e., cue switches from read the red prime word to read the white probe word). Second, negative priming occurred for identical words, but not for semantically related words, whether related categorically or associatively. This pattern of results is consistent with a memory retrieval account, but not with an inhibition account of negative priming, and casts doubt on whether there is semantic negative priming for words.     

What does "being American" mean? A comparison of Asian American and European American young adults

Two studies found that the meaning of "being American" differs for Asian Americans and European Americans. In Study 1, Hmong and European American undergraduates described what "being American" meant to them. In Study 2, Chinese American and European American undergraduates described what "American culture" meant to them. Responses were coded for references to cultural exposure, customs/traditional behavior, ethnic diversity, political ideology, and patriotism. Across both studies, Asian Americans referred to American customs and traditional behavior more than European Americans. European Americans referred to patriotism more than Hmong (in Study 1) and to ethnic diversity more than Chinese Americans (in Study 2). The authors suggest that these differences reflect the distinct statuses, concerns, and experiences of Asian Americans and European Americans.     

Trust in God: The COVID-19 Pandemic's Impact on Religiosity in China

Emerging research shows the COVID-19 pandemic has made substantial changes to the religious climate of several nations. Surprisingly, China, the outbreak center of the pandemic, has been scarcely researched. Our study investigates how the COVID-19 pandemic has evoked new religious disaster responses and provided psychological coping mechanisms during the pandemic. We also explore how the pandemic explains surprising rates of religiosity in China. Scholars have long proposed that religious resurgence in China has been a result of individuals seeking stability in turbulent times. We bridge parallel Literatures in these areas and treat the pandemic as a natural experiment for evaluating religious behavior over time as conditioned by heightened risk perception. Utilizing a difference-in-differences estimation strategy with panel data, our study reveals that the pandemic has led to a significant increase in religiosity in China, particularly in religious areas most affected by the pandemic. We propose that even in a highly regulative religious environment, with most of its population being religiously unaffiliated, religion is a significant resource for coping in China. We take an innovative approach to demonstrate this by utilizing online search data. Our research speaks to the sociology of religion, the social psychology of risk perception, and makes application to emerging research on the unfolding COVID-19 pandemic.     

实习初期教师职业认同的发展轨迹及其与主动性人格的关系:一项追踪研究

采用主动性人格量表、工作绩效量表、人际关系量表、教师职业认同量表对385名实习教师从其实习第一周起连续追踪测量五周,利用多层线性模型探讨实习初期教师职业认同的发展轨迹,以及主动性人格对教师职业认同的影响及其机制。结果表明：(1)实习初期教师职业认同呈先高后低再升高的U型非线性发展趋势;(2)工作绩效和人际关系在主动性人格与教师职业认同之间起部分中介作用,且工作绩效的中介效应显著大于人际关系的中介效应。研究结果不仅揭示了实习初期教师职业认同的动态发展轨迹,同时还揭示了主动性人格影响教师职业认同的中介机制,对提升教师培养质量具有重要的参考价值。     

Broad Consent for Research With Biological Samples: Workshop Conclusions

Different types of consent are used to obtain human biospecimens for future research. This variation has resulted in confusion regarding what research is permitted, inadvertent constraints on future research, and research proceeding without consent. The National Institutes of Health (NIH) Clinical Center's Department of Bioethics held a workshop to consider the ethical acceptability of addressing these concerns by using broad consent for future research on stored biospecimens. Multiple bioethics scholars, who have written on these issues, discussed the reasons for consent, the range of consent strategies, and gaps in our understanding, and concluded with a proposal for broad initial consent coupled with oversight and, when feasible, ongoing provision of information to donors. This article describes areas of agreement and areas that need more research and dialogue. Given recent proposed changes to the Common Rule, and new guidance regarding storing and sharing data and samples, this is an important and timely topic.     

Intrinsicality and Grounding

A number of philosophers have recently claimed that intrinsicality can be analysed in terms of the metaphysical notion of grounding. Since grounding is a hyperintensional notion, accounts of intrinsicality in terms of grounding, unlike most other accounts, promise to be able to discriminate between necessarily coextensive properties that differ in whether they are intrinsic. They therefore promise to be compatible with popular metaphysical theories that posit necessary entities and necessary connections between wholly distinct entities, on which it is plausible that there are such properties. This paper argues that this promise is illusory. It is not possible to give an analysis of intrinsicality in terms of grounding that is consistent with these theories. Given an adequate analysis should be compatible with these theories, it follows that it is not possible to analyse intrinsicality in terms of grounding.     

The Effectiveness of Functional Family Therapy in Reducing Adolescent Mental Health Risk and Family Adjustment Difficulties in an Irish Context

To evaluate the effectiveness of Functional Family Therapy (FFT) 42 cases were randomized to FFT and 55 to a waiting‐list control group. Minimization procedures controlled the effects of potentially confounding baseline variables. Cases were treated by a team of five therapists who implemented FFT with a moderate degree of fidelity. Rates of clinical recovery were significantly higher in the FFT group than in the control group. Compared to the comparison group, parents in the FFT group reported significantly greater improvement in adolescent problems on the Strengths and Difficulties Questionnaire (SDQ) and both parents and adolescents reported improvements in family adjustment on the Systemic Clinical Outcomes and Routine Evaluation (SCORE). In addition, 93% of youth and families in the treatment condition completed FFT. Improvements shown immediately after treatment were sustained at 3‐month follow‐up. Results provide a current demonstration of FFT's effectiveness for youth with behavior problems in community‐based settings, expand our understanding of the range of positive outcomes of FFT to include mental health risk and family‐defined problem severity and impact, and suggests that it is an effective intervention when implemented in an Irish context.     

The Varieties of Intrinsicality

Intrinsicality is a central notion in metaphysics that can do important work in many areas of philosophy. It is not widely appreciated, however, that there are in fact a number of different notions of intrinsicality, and that these different notions differ in what work they can do. This paper discusses what these notions are, describes how they are related to each other, and argues that each of them can be analysed in terms of a single notion of intrinsic aboutness that relates states of affairs to the things they are intrinsically about.
