Inferences from disclosures about the truth and falsity of expert testimony

Participants acting as mock jurors made inferences about whether a person was a suspect in a murder based on an expert's testimony about the presence of objects at the crime scene and the disclosure that the testimony was true or false. Experiment 1 showed that participants made more correct inferences, and made inferences more quickly, when the truth or falsity of the expert's testimony was disclosed immediately after the testimony rather than when the disclosure was delayed. Experiment 2 showed no advantage for prior disclosure over immediate disclosure. Experiment 3 showed that the pattern of inferences when there was no disclosure mirrored the pattern when it was disclosed that the expert's testimony was true rather than false. Participants made more correct inferences from true conjunctions than disjunctions, and from false disjunctions than conjunctions. We discuss the implications for theories of the mental representations and cognitive processes that underlie human reasoning.     

Why Frankenstein is a Stigma Among Scientists

As one of the best known science narratives about the consequences of creating life, Mary Shelley’s Frankenstein; or, The Modern Prometheus (1818) is an enduring tale that people know and understand with an almost instinctive familiarity. It has become a myth reflecting people’s ambivalent feelings about emerging science: they are curious about science, but they are also afraid of what science can do to them. In this essay, we argue that the Frankenstein myth has evolved into a stigma attached to scientists that focalizes the public’s as well as the scientific community’s negative reactions towards certain sciences and scientific practices. This stigma produces ambivalent reactions towards scientific artifacts and it leads to negative connotations because it implies that some sciences are dangerous and harmful. We argue that understanding the Frankenstein stigma can empower scientists by helping them revisit their own biases as well as responding effectively to people’s expectations for, and attitudes towards, scientists and scientific artifacts. Debunking the Frankenstein stigma could also allow scientists to reshape their professional identities so they can better show the public what ethical and moral values guide their research enterprises.     

The Effects of Linguistic Devices on Consumer Information Processing and Persuasion: A Language Complexity × Processing Mode Framework

People—be they politicians, marketers, job candidates, product reviewers, or romantic interests—often use linguistic devices to persuade others, and there is a sizeable literature that has documented the effects of numerous linguistic devices. However, understanding the implications of these effects is difficult without an organizing framework. To this end, we introduce a Language Complexity × Processing Mode Framework for classifying linguistic devices based on two continuous dimensions: language complexity, ranging from simple to complex, and processing mode, ranging from automatic to controlled. We then use the framework as a basis for reviewing and synthesizing extant research on the effects of the linguistic devices on persuasion, determining the conditions under which the effectiveness of the linguistic devices can be maximized, and reconciling inconsistencies in prior research.     

Moral (dis)engagement with anthropogenic climate change in online comments on newspaper articles

Anthropogenic climate change (ACC) is widely acknowledged to be morally significant, but little is known about everyday moralising around ACC. We addressed this gap via quantified thematic analysis of 300 online comments to British newspaper articles on ACC, drawing on Bandura's moral disengagement theory. Moral disengagement through denial of ACC was widespread. Other disengagement strategies, such as palliative comparison and diminishing agency, occurred less often. There was also some moral engagement, most often through assertions of the existence of ACC and/or its harmful effects. Moral disengagement was significantly more common in comments on right wing than left wing newspapers, whereas the opposite was true of moral engagement. Although Bandura's framework provided a useful starting point to make sense of ACC moralising, it did not capture moral concerns that extended beyond its “harm/care” remit. In particular, many “denial” comments included a “dishonesty” discourse, whereby ACC proponents were accused of deception for ulterior motives. To classify this discourse as moral disengagement obscures its engagement with a different set of moral issues around trust and honesty. We suggest that Bandura's theory represents one possible “moral landscape” around ACC and could be extended to encompass a broader range of moral concerns.     

Very Young Child Well-being in Military Families: A Snapshot

Since the September 11th attacks on the U.S., more than 2 million children have experienced parental deployment during their early years, with potentially lasting impact. When a parent is deployed, a number of factors may affect the well-being of the service member and his/her family. One parental factor—posttraumatic stress disorder or distress—might be particularly powerful in its effect on young children and the family system. We analyzed baseline data from an intervention development project which focused on supporting military families with very young children during post-deployment. The purpose of this research is to understand the relationships between parental mental health status, parenting stress, couple functioning, and young child well-being. The effects of mental health status of home-front and service member parents and the role of couple functioning on parent–child interactions and behavioral problems of young children were examined in a sample of military families during the post-deployment period. Findings suggest that service member posttraumatic stress symptoms are associated with higher parental report of child behavior problems. Higher quality of the couple relationship appears to lessen the impact of parental posttraumatic stress but is not related to parent perceptions of child behavior concerns. Implications for future research with military families are discussed.     

Perception of objects oriented downward from a vertical position

In the present work we investigated people’s perceptions of orientation for surfaces that are conceived of as being sloped downward from vertical against a vertical reference frame. In the three conditions of Experiment 1, participants either (1) placed a ladder against a wall at what they thought was the most stable position, and then estimated its orientation; (2) gave a verbal (conceptual) estimate of what the most stable position of a ladder leaned against a wall would be; or (3) drew a line representing the most stable position of a ladder to be placed against a wall, and then gave a verbal estimate of the ladder’s orientation. Ladder placement was shallower than the most stable position, as were the verbal estimations of both the positioned and drawn orientations and the verbal (conceptual) estimates of the most stable position for a ladder to be leaned against a wall, relative to the actual orientations. In Experiment 2, participants verbally estimated various ladder orientations. The estimates were again shallower than the actual orientations. For orientations between 60° and 90°, the estimates showed a scale compression effect from horizontal. This perceived exaggeration of the orientation of an object typically oriented down from vertical is similar to the perceived exaggeration of the orientation of hills and ramps, typically thought of as oriented up from horizontal. This may point to a generic perceived exaggeration of slant whose direction depends on the conceptual or actual reference frame being used.
