How Many People Are Exposed to Suicide? Not Six

It has long been stated that six people are left behind following every suicide. Despite a lack of empirical evidence, this has been extensively cited for over 30 years. Using data from a random‐digit dial survey, a more accurate number of people exposed to each suicide is calculated. A sample of 1,736 adults included 812 lifetime suicide‐exposed respondents who reported age and number of exposures. Each suicide resulted in 135 people exposed (knew the person). Each suicide affects a large circle of people, who may be in need of clinician services or support following exposure.     

Are Some of the Things Faculty Do to Maximize Their Student Evaluation of Teachers Scores Unethical?

This paper provides a philosophical analysis of some of the things faculty do to maximize their Student Evaluation of Teachers (SET) scores. It examines 28 practices that are claimed to be unethical methods for maximizing SET scores. The paper offers an argument concerning the morality of each behavior and concludes that 13 of the 28 practices suggest unethical behavior. The remaining 15 behaviors are morally permissible.     

Are Closed‐Minded People More Open to the Idea of Killing Themselves?

This article summarizes the author's work on Openness to Experience (a personality trait) and suicidal behavior. It appears that people who obtain low scores on an inventory measuring Openness to Experience are less likely to report suicidal ideation but more likely to take their own lives. How can this apparent discrepancy be reconciled? Based on the premise that the expression of suicidal ideation can have adaptive consequences (e.g., by mobilizing family and treatment providers), it is hypothesized that people with major depression who are low in Openness may be at increased risk for completed suicide in part because they are less likely to feel, or report feeling, suicidal.     

How Many Mechanisms Are Needed to Analyze Speech? A Connectionist Simulation of Structural Rule Learning in Artificial Language Acquisition

Some empirical evidence in the artificial language acquisition literature has been taken to suggest that statistical learning mechanisms are insufficient for extracting structural information from an artificial language. According to the more than one mechanism (MOM) hypothesis, at least two mechanisms are required in order to acquire language from speech: (a) a statistical mechanism for speech segmentation; and (b) an additional rule-following mechanism in order to induce grammatical regularities. In this article, we present a set of neural network studies demonstrating that a single statistical mechanism can mimic the apparent discovery of structural regularities, beyond the segmentation of speech. We argue that our results undermine one argument for the MOM hypothesis.     

Do They Know How Happy They Are? On the Value of Self-Rated Happiness of People With a Mental Disorder

Quality of life is often measured using questions about happiness. This method presumes that respondents are able to judge their life. Research suggest that this is typically the case, but this is not to say that everybody can. In that context one may doubt whether people with a mental disorder can judge their life adequately. Happiness can be rejected as a indicator for quality of life for people with mental disorders, because of affective and cognitive distortions. We therefore checked the validity of happiness and satisfaction measures in the context of mental disorders. Psychiatric diagnoses were determined at baseline and at 12 and 36 months follow-up in a representative sample (N = 7,076) of the Dutch population, using a full Composite International Diagnostic Interview. Respondents indicated how often they had felt happy during the past month and how satisfied they were with their lives in general. The measurements have a satisfactory concurrent, ecological and predictive validity for people with mental disorders. Though the level of happiness is lower among the people with mental disorders, conditions for happiness and contentment appear to be similar.     

Are the Effects of Height on Well-Being a Tall Tale?

Numerous papers have documented a positive association between height and good physical health and also with good economic outcomes such as earnings. A smaller number have argued for an association with well-being. In this paper, the SHARE survey of over 50 year olds in Europe is used to analyse whether individuals’ height is associated with higher or lower levels of life-satisfaction using ordered probit estimation. In simple models there is a positive, concave relationship between height and life satisfaction. However it is shown that the results are quite sensitive to the inclusion of controls reflecting demographics and, in particular, human capital and health status. Where effects do exist, it is predominantly at low to medium levels of height. That is there is a penalty, in well-being terms, to being short but not necessarily a benefit to being tall. There is also evidence of heterogeneity across countries with the effects being best determined in France.     

Are People Polite to Computers? Responses to Computer-Based Interviewing Systems1

The present studies were designed to test whether people are “polite” to computers. Among people, an interviewer who directly asks about him- or herself will receive more positive and less varied responses than if the same question is posed by a third party. Two studies were designed to determine if the same phenomenon occurs in human–computer interaction. In the first study (N= 30), participants performed a task with a text-based computer and were then interviewed about the performance of that computer on 1 of 3 loci: (a) the same computer, (b) a paper-and-pencil questionnaire, or (c) a different (but identical) text-based computer. Consistent with the politeness prediction, same-computer participants evaluated the computer more positively and more homogeneously than did either paper-and-pencil or different-computer participants. Study 2 (N= 30) replicated the results with voice-based computers. Implications for computer-based interviewing are discussed.     

Does the Argument from Realization Generalize? Responses to Kim

By quantifying over properties we cannot create new properties any more than by quantifying over individuals we can create new individuals. Someone murdered Jones, and the murderer is either Smith or Jones or Wang. That “someone,” who murdered Jones, is not a person in addition to Smith, Jones, and Wang, and it would be absurd to posit a disjunctive person, Smith‐or‐Jones‐or‐Wang, with whom to identify the murderer. The same goes for second‐order properties and their realizers. (Kim 1997a, 201)     

Are ants sensitive to the geometry of tunnel bifurcation?

The ability to orient and navigate in space is essential for all animals whose home range is organized around a central point. Because of their small home range compared to vertebrates, central place foraging insects such as ants have for a long time provided a choice model for the study of orientation mechanisms. In many ant species, the movement of individuals on their colony home range is achieved essentially collectively, on the chemical trails laid down by their nest mates. In the initial stage of food recruitment, these trails can cross each other and thus form a network of interconnected paths in which ants have to orient. Previous simulation studies have shown that ants can find the shortest path between their nest and a food source in such a network only if there is a bias in the branch they choose when they reach an asymmetrical bifurcation. In this paper, we studied the choice of ants when facing either a symmetrical or an asymmetrical bifurcation between two tunnels. Ants were tested either on their way to a food source or when coming back to their nest, and either in the presence or in the absence of a chemical trail. Overall, our results show that the choice of an ant at a tunnel bifurcation depends more on the presence/absence of a trail pheromone than on the geometry of the bifurcation itself.     

How do the internal details of the object contribute to recognition?

Object recognition becomes difficult when the main axis of the object is foreshortened. It has previously been reported that this so-called foreshortened disadvantage is larger when the silhouette of the object is presented than when the line drawing of the object is presented. The pronounced foreshortened disadvantage in silhouette recognition indicates that the internal details of the object, which are absent in the silhouette, provide useful information, particularly when the main axis is foreshortened. But the role of these internal details remains controversial. One account for the pronounced disadvantage is that the internal details contribute to the derivation of the main axis. The other account is that internal details provide the distinctive features that are directly matched to the object represented in memory. The aim in the present study was to determine which of these two explanations best accounts for the differential foreshortened disadvantage between line drawings and silhouettes. To reduce the uncertainty regarding the axis orientation, a 3-D arrow indicating the orientation of the main axis was presented as a cue before the object itself was presented. As a result, the difference in the foreshortened disadvantage between silhouettes and line drawings disappeared. This indicated that the pronounced foreshortened disadvantage for silhouettes was caused by a lack of axis information. In other words, the internal details provided the information necessary for axis derivation when the axis was foreshortened.     

How Do People React to Stigma Acknowledgment? Race and Gender Acknowledgment in the Context of the 2008 Presidential Election1

Some studies have found that acknowledging one's stigmatized social identity in an evaluative context leads to more favorable evaluations, whereas others have found that stigma acknowledgment can increase negative evaluations. The present study examined one potential factor (i.e., evaluators' attitudes toward social groups to which acknowledgers belong) that may moderate the relation between stigma acknowledgment and evaluations, in the context of race and gender acknowledgment in the 2008 U.S. presidential election. Results indicated that acknowledgment of race, but not gender, led to more negative evaluations, particularly for high‐prejudiced individuals. The findings highlight the importance of examining stigma acknowledgment effects from a Person × Situation perspective. Implications for advancing understanding of acknowledgment as a useful strategy in evaluative contexts are discussed.     

Distraction of Counting by the Meaning of Background Speech: Are Spatial Memory Demands a Prerequisite?

This paper reexamines the effects of background speech on counting. Previous studies have shown that background sound disrupts counting in comparison with silence, but the magnitude of disruption is no larger for spoken numbers compared with that for non‐number speech (there is no effect of the meaning of background speech). The typical task used previously has been to count the number of sequentially presented visual events. We replicated the general finding in Experiment 1—that there is no effect of the meaning of background speech—in the context of the classic sequence counting task. In Experiment 2, the task was changed by having to‐be‐counted dots presented simultaneously and randomly across the visual field. Here, an effect attributable to the meaning of background speech emerged. Background speech that is similar in meaning to the focal task process contributes to the magnitude of disruption, but apparently only when spatial memory processes are a task prerequisite.

How Might We Address the Factors that Contribute to the Scarcity of Philosophers Who Are Women and/or of Color?

Professional philosophy in the US remains relatively homogenous. I use four anecdotes to amplify some of the practices that may contribute to the dearth of underrepresented philosophers. Each anecdote highlights a different problem—lack of proper mentoring, stereotype threat, difficulties navigating sexism, and a sense of exclusion. Although I discuss each of these issues separately, it is certainly the case that these (and other issues) can and often do occur concurrently. I offer preliminary thoughts on how these problems could be addressed while keeping in mind that philosophy in the US is a microcosm of the larger US society.     

What is the Right Thing to Say? Agreement among Perceivers on the Supportiveness of Statements

Most social support theory implies that there are objectively supportive people and statements. Yet there is little agreement among perceivers that some people are more supportive than others. Nonetheless, there might be better agreement regarding supportive statements. In three studies, children, college students, and members of a clinical training program rated the supportiveness of specific statements presented by text or video. Agreement among perceivers accounted for only 11% of the variance (range = 8%–12%). Perceivers disagreed because of their traitlike perceptual biases, as well as perceivers’ idiosyncratic tastes. Implications for social support theory were discussed.
