Genetic Counselors’ Perspectives About Cell-Free DNA: Experiences,Challenges, and Expectations for Obstetricians

The expansion of cell-free fetal DNA (cfDNA) screening for a larger and diverse set of genetic variants, in addition for use among the low-risk obstetric population, presents important clinical challenges for all healthcare providers involved in the delivery of prenatal care. It is unclear how to leverage the different members of the healthcare team to respond to these challenges. We conducted interviews with 25 prenatal genetic counselors to understand their experience with the continued expansion of cfDNA screening. Participants supported the use of cfDNA screening for the common autosomal aneuploidies, but noted some reservations for its use to identify fetal sex and microdeletions. Participants reported several barriers to ensuring that patients have the information and support to make informed decisions about using cfDNA to screen for these different conditions. This was seen as a dual-sided problem, and necessitated additional education interventions that addressed patients seeking cfDNA screening, and obstetricians who introduce the concepts of genetic risk and cfDNA to patients. In addition, participants noted that they have a professional responsibility to educate obstetricians about cfDNA so they can be prepared to be gatekeepers of counseling and education about this screening option for use among the general obstetric population.     

Treatment of elopement following a latency‐based interview‐informed,synthesized contingency analysis

Using a latency measure during a functional analysis of problem behavior increases the brevity of the assessment period and decreases risks resulting from exposure to contexts intended to evoke problem behavior. In addition, latency‐based functional analyses may be especially suitable for discrete behaviors such as elopement, which require resetting the environment after each instance of the response. We evaluated a comprehensive assessment and treatment package for the elopement of two children diagnosed with autism. We observed short latencies to elopement during the test condition of the analysis and no elopement during the control condition. We then taught the participants multiple forms of functional communication responses of increasing complexity while elopement was blocked. This was followed by the thinning of reinforcement to a terminal goal, creating a treatment package that nearly eliminated elopement and was socially validated by caregivers.     

Facts and Possibilities: A Model‐Based Theory of Sentential Reasoning

This article presents a fundamental advance in the theory of mental models as an explanation of reasoning about facts, possibilities, and probabilities. It postulates that the meanings of compound assertions, such as conditionals (if) and disjunctions (or), unlike those in logic, refer to conjunctions of epistemic possibilities that hold in default of information to the contrary. Various factors such as general knowledge can modulate these interpretations. New information can always override sentential inferences; that is, reasoning in daily life is defeasible (or nonmonotonic). The theory is a dual process one: It distinguishes between intuitive inferences (based on system 1) and deliberative inferences (based on system 2). The article describes a computer implementation of the theory, including its two systems of reasoning, and it shows how the program simulates crucial predictions that evidence corroborates. It concludes with a discussion of how the theory contrasts with those based on logic or on probabilities.     

Teenagers’ Perceptions of Volunteering Following the 2010–2011 Canterbury Earthquakes,New Zealand

ABSTRACT

Limited research exists of teenagers’ involvement in the response phase of a natural disaster. There is little, for example on volunteering, and of specifically what motivates teenagers to volunteer and the activities they participate in. Therefore, this study investigated teenagers’ involvement and perceptions of volunteering following the 2010–2011 Canterbury, New Zealand, earthquakes. Six focus groups were conducted with 31 teenagers aged 16–18 who had experienced the earthquakes. The data were analyzed using thematic analysis leading to four themes, namely sense of control, sense of purpose, shift in perspective, and restrictions. Findings emphasize the importance of organizing youth-focused volunteer groups, due to volunteering potentially reducing teenagers’ psychological distress postdisaster.     

Dissecting stimulus–response binding effects: Grouping by color separately impacts integration and retrieval processes

In selection tasks, target and distractor features can be encoded together with the response into the same short-lived memory trace, or event file (see Hommel, 2004), leading to bindings between stimulus and response features. The repetition of a stored target or distractor feature can lead to the retrieval of the entire episode, including the response—so-called “binding effects.” Binding effects due to distractor repetition are stronger for grouped than for nongrouped target and distractor stimulus configurations. Modulation of either of two mechanisms that lead to the observed binding effects might be responsible here: Grouping may influence either stimulus–response integration or stimulus–response retrieval. In the present study we investigated the influences of grouping on both mechanisms independently. In two experiments, target and distractor letters were grouped (or nongrouped) via color (dis)similarity separately during integration and retrieval. Grouping by color similarity affected integration and retrieval mechanisms independently and in different ways. Color dissimilarity enhanced distractor-based retrieval, whereas color similarity enhanced distractor integration. We concluded that stimulus grouping is relevant for binding effects, but that the mechanisms that contribute to binding effects should be carefully separated.

Perceived collective continuity and attitudes toward outgroups

In a series of six studies, we examined the role that perceived collective continuity (PCC) plays in intergroup attitudes. While the extant literature focuses on attitudes toward ingroups, the current studies chose to expand upon this research by concentrating on three types of outgroups (national, religious, and organizational). Results indicated that for groups perceived as neutral or positive, increased PCC was associated with more positive attitudes, while for enemy groups, increased PCC was associated with more negative attitudes. Entitativity played a mediating role such that as the outgroup was perceived as more continuous, it was also seen as more entitative. Higher entitativity led to less negative attitudes toward a past ally but more negative attitudes toward a past enemy. Results held whether past conflict and PCC were measured or manipulated, further supporting our findings. PCC has negative or positive implications for judgments of outgroups depending on intergroup history. Copyright © 2016 John Wiley & Sons, Ltd.     

Are NFL Arrestees Violent Specialists or High Frequency Offenders or Both?

Although recent research showed that NFL players have a higher violent crime arrest rate, it remains unclear whether, at the individual-level, NFL players who are arrested are specializing in violent crimes or whether their involvement in violence is driven largely by their high frequency of offending. Using two publically available databases on NFL player arrests, our results show that high frequency offending is rare among the arrested NFL players, that non-white players are more chronic than white players, and that the likelihood of violence is largely driven by high frequency offending—especially among non-white players. Importantly, there appears to be no specialization-in-violence among this sample of arrested NFL players.     

Feeling Hopeful Inspires Support for Social Change

Hope is an emotion that has been implicated in social change efforts, yet little research has examined whether feeling hopeful actually motivates support for social change. Study 1 (N = 274) confirmed that hope is associated with greater support for social change in two countries with different political contexts. Study 2 (N = 165) revealed that hope predicts support for social change over and above other emotions often investigated in collective action research. Study 3 (N = 100) replicated this finding using a hope scale and showed the effect occurs independent of positive mood. Study 4 (N = 58) demonstrated experimentally that hope motivates support for social change. In all four studies, the effect of hope was mediated by perceived efficacy to achieve social equality. This research confirms the motivating potential of hope and illustrates the power of this emotion in generating social change.
