Effects of validity screening items on adolescent survey data

In 2 studies, we examined the use of validity screening items in adolescent survey data. In each study, adolescent respondents were asked whether they were telling the truth and paying attention in answering survey questions. In Study 1 (N = 7,801), the prevalence rates of student risk behaviors were significantly lower after inappropriate (invalid) responders were screened out of the sample. In addition, confirmatory and multigroup factor analyses demonstrated significant differences between the factor structures of school climate scales with valid versus invalid responders. In Study 2, student perceptions of school climate were correlated with teacher perceptions in 291 schools. A bootstrap resampling procedure compared the correlations obtained with valid versus invalid responding students in each school and found that valid responders had more positive views of school conditions and produced higher correlations with teacher perceptions. These findings support the value of validity screening items in improving the quality of adolescent survey data.     

Decision making in the Balloon Analogue Risk Task (BART): Anterior cingulate cortex signals loss aversion but not the infrequency of risky choices

The inferior frontal gyrus/anterior insula (IFG/AI) and anterior cingulate cortex (ACC) are key regions involved in risk appraisal during decision making, but accounts of how these regions contribute to decision making under risk remain contested. To help clarify the roles of these and other related regions, we used a modified version of the Balloon Analogue Risk Task (Lejuez et al., Journal of Experimental Psychology: Applied, 8, 75-84, 2002) to distinguish between decision-making and feedback-related processes when participants decided to pursue a gain as the probability of loss increased parametrically. Specifically, we set out to test whether the ACC and IFG/AI regions correspond to loss aversion at the time of decision making in a way that is not confounded with either reward-seeking or infrequency effects. When participants chose to discontinue inflating the balloon (win option), we observed greater ACC and mainly bilateral IFG/AI activity at the time of decision as the probability of explosion increased, consistent with increased loss aversion but inconsistent with an infrequency effect. In contrast, we found robust vmPFC activity when participants chose to continue inflating the balloon (risky option), consistent with reward seeking. However, in the cingulate and in mainly bilateral IFG regions, blood-oxygenation-level-dependent activation decreased when participants chose to inflate the balloon as the probability of explosion increased, findings that are consistent with a reduced loss aversion signal. Our results highlight the existence of distinct reward-seeking and loss-averse signals during decision making, as well as the importance of distinguishing between decision and feedback signals.     

Heartwarming memories: Nostalgia maintains physiological comfort

Nostalgia, a sentimental longing or wistful affection for the past, is a predominantly positive and social emotion. Recent evidence suggests that nostalgia maintains psychological comfort. Here, we propose, and document in five methodologically diverse studies, a broader homeostatic function for nostalgia that also encompasses the maintenance of physiological comfort. We show that nostalgia--an emotion with a strong connotation of warmth--is triggered by coldness. Participants reported stronger nostalgia on colder (vs. warmer) days and in a cold (vs. neutral or warm) room. Nostalgia, in turn, modulates the interoceptive feeling of temperature. Higher levels of music-evoked nostalgia predicted increased physical warmth, and participants who recalled a nostalgic (vs. ordinary autobiographical) event perceived ambient temperature as higher. Finally, and consistent with the close central nervous system integration of temperature and pain sensations, participants who recalled a nostalgic (vs. ordinary autobiographical) event evinced greater tolerance to noxious cold.     

Philosophy,Logic, Science,History

Analytic philosophy is sometimes said to have particularly close connections to logic and to science, and no particularly interesting or close relation to its own history. It is argued here that although the connections to logic and science have been important in the development of analytic philosophy, these connections do not come close to characterizing the nature of analytic philosophy, either as a body of doctrines or as a philosophical method. We will do better to understand analytic philosophy—and its relationship to continental philosophy—if we see it as a historically constructed collection of texts, which define its key problems and concerns. It is true, however, that analytic philosophy has paid little attention to the history of the subject. This is both its strength—since it allows for a distinctive kind of creativity—and its weakness—since ignoring history can encourage a philosophical variety of “normal science.”     

Religious Diversity in Mexico: Socioeconomic Attainment and Family Structure

Mexico has experienced dynamic changes in its religious landscape, but relatively little is known about the ways in which the affiliates of the diverse religious groups differ in their socioeconomic and family characteristics. This paper examines religious group differences in key demographic indicators of socioeconomic status and family structure using the 2000 Mexican Census. The changing patterns of religious affiliation in Mexico signal increasing religious, socioeconomic and familial diversity. Non-Christians and Mormons stand out for having higher scores on education and the wealth index relative to other religious groups. Most groups have lower rates of consensual unions and higher rates of marriage than do Catholics. These same groups also tend to have larger families and lower divorce/separation. These trends seem inconsistent with the Catholic teachings about marriage, divorce and contraception. Apparently, new groups are attracting adherents who have family orientations that differ from main-stream Mexican society.     

The strategic logic of costly punishment necessitates natural field experiments, and at least one such experiment exists

Costly punishment's scarcity "in the wild" does not belie strong reciprocity theory as Guala claims. In the presence of strong reciprocators, strategic defectors will cooperate and sanctioning will not occur. Accordingly, natural field experiments are necessary to assess a "wide" reading of costly punishment experiments. One such field experiment exists, and it supports the hypothesis that costly punishment promotes cooperation.     

The multifinality constraints effect: how goal multiplicity narrows the means set to a focal end

In the presence of several objectives, goal conflict may be avoided via multifinal means, which advance all of the active goals at once. Because such means observe multiple constraints, they are fewer in number than the unconstrained means to a single goal. Five experimental studies investigated the process of choosing or generating such means for multiple goals. We found that the simultaneous activation of multiple goals restricted the set of acceptable means to ones that benefitted (or at least, did not harm) the entire set of active goals. Two moderators of this phenomenon were identified: (a) the feasibility of identifying multifinal means, which was dependent on the relations between the different active goals, and (b) the enhanced importance of the focal goal, which resulted in the inhibition of its alternatives and the consequent relaxation of multifinality constraints.     

The Relationship Between Phonological Memory,Phonological Sensitivity,and Incidental Word Learning

This study investigated the cognitive abilities needed to succeed at incidental word learning, specifically by examining the role of phonological memory and phonological sensitivity in novel word learning by 4-year-olds who were typically developing. Forty 4-year-olds were administered a test of nonword repetition (to investigate phonological memory), rhyming and phoneme alliteration tasks (to investigate phonological sensitivity), and an incidental word learning task (via a computer-based presentation of a cartoon story). A multiple regression analysis revealed that nonword repetition scores did not contribute significantly to incidental word learning. Phonological sensitivity scores were significant predictors of incidental word learning. These findings provide support for a model of lexical acquisition in which phonological knowledge plays an important role.     

Children Exposed to the Arrest of a Family Member: Associations with Mental Health

The arrest of a parent or other family member can be detrimental to children’s health. To study the impact of exposure to the arrest of a family member on children’s mental health and how said association may change across developmental periods, we examined baseline data for children (birth through 11 years) entering family-based systems of care (SOC). Children exposed to the arrest of a family member had experienced significantly more 5.38 (SD = 2.59) different types of potentially traumatic events (PTE) than children not exposed to arrest 2.84 (SD = 2.56). Multiple regression model results showed that arrest exposure was significantly associated with greater behavioral and emotional challenges after controlling for children’s age, gender, race/ethnicity, household income, caregiver’s education, parenting factors, and other PTE exposure. Further analyses revealed differences in internalizing and externalizing behaviors associated with arrest exposure across developmental levels. This study highlights some of the mental health challenges for children exposed to the arrest of a family member, while adding to our knowledge of how such an event affects children across different developmental periods. More trauma-informed, developmentally appropriate systems need to be in place at all levels to assist children and families experiencing arrest.     

Psychopathy: what apology making tells us about moral agency

Psychopathy is often used to settle disputes about the nature of moral judgment. The “trolley problem” is a familiar scenario in which psychopathy is used as a test case. Where a convergence in response to the trolley problem is registered between psychopathic subjects and non-psychopathic (normal) subjects, it is assumed that this convergence indicates that the capacity for making moral judgments is unimpaired in psychopathy. This, in turn, is taken to have implications for the dispute between motivation internalists and motivation externalists, for instance. In what follows, we want to do two things: firstly, we set out to question the assumption that convergence is informative of the capacity for moral judgment in psychopathy. Next, we consider a distinct feature of psychopathy which we think provides strong grounds for holding that the capacity for moral judgment is seriously impaired in psychopathic subjects. The feature in question is the psychopathic subject’s inability to make sincere apologies. Our central claim will be this: convergence in response to trolley problems does not tell us very much about the psychopathic subject’s capacity to make moral judgments, but his inability to make sincere apologies does provide us with strong grounds for holding that this capacity is seriously impaired in psychopathy.
