Longitudinal Analysis of Particulate Air Pollutants and Adolescent Delinquent Behavior in Southern California

Animal experiments and cross-sectional human studies have linked particulate matter (PM) with increased behavioral problems. We conducted a longitudinal study to examine whether the trajectories of delinquent behavior are affected by PM_2.5 (PM with aerodynamic diameter?≤?2.5 μm) exposures before and during adolescence. We used the parent-reported Child Behavior Checklist at age 9–18 with repeated measures every ~2–3 years (up to 4 behavioral assessments) on 682 children from the Risk Factors for Antisocial Behavior Study conducted in a multi-ethnic cohort of twins born in 1990–1995. Based on prospectively-collected residential addresses and a spatiotemporal model of ambient air concentrations in Southern California, monthly PM_2.5 estimates were aggregated to represent long-term (1-, 2-, 3-year average) exposures preceding baseline and cumulative average exposure until the last assessment. Multilevel mixed-effects models were used to examine the association between PM_2.5 exposure and individual trajectories of delinquent behavior, adjusting for within-family/within-individual correlations and potential confounders. We also examined whether psychosocial factors modified this association. The results sμggest that PM_2.5 exposure at baseline and cumulative exposure during follow-up was significantly associated (p?<?0.05) with increased delinquent behavior. The estimated effect sizes (per interquartile increase of PM_2.5 by 3.12–5.18 μg/m³) were equivalent to the difference in delinquency scores between adolescents who are 3.5–4 years apart in age. The adverse effect was stronger in families with unfavorable parent-to-child relationships, increased parental stress or maternal depressive symptoms. Overall, these findings sμggest long-term PM_2.5 exposure may increase delinquent behavior of urban-dwelling adolescents, with the resulting neurotoxic effect aggravated by psychosocial adversities.     

Quality Choice and Product Differentiation in Monopoly Theory: An Application to the Puritan Church

French engineer and transport economist Jules Dupuit (1804–1866) conjectured more than 150 years ago that, in the context of a three‐part tariff concerning French railroads, a discriminating monopolist will find it most profitable to distort product (service) quality at each of the two ends of the quality spectrum in order to prevent consumers in the middle class (i.e., the second of three classes) from defecting to either end (i.e., first or third class). This study extends a branch of the literature on the economics of religion by arguing that 17th‐century Puritan theologians in colonial America used, in a way that is consistent with Dupuit's insights, Puritan religious doctrines related to eternal salvation and witchcraft to distort the quality, at both ends of the quality spectrum in a three‐part tariff construct, of the religious services they provided to their parishioners. In doing so, we employ economic modeling from seminal studies of the medieval Roman Catholic Church.     

Age of acquisition and imageability ratings for a large set of words, including verbs and function words

Age of acquisition and imageability ratings were collected for 2,645 words, including 892 verbs and 213 function words. Words that were ambiguous as to grammatical category were disambiguated: Verbs were shown in their infinitival form, and nouns (where appropriate) were preceded by the indefinite article (such asto crack anda crack). Subjects were speakers of British English selected from a wide age range, so that differences in the responses across age groups could be compared. Within the subset of early acquired noun/verb homonyms, the verb forms were rated as later acquired than the nouns, and the verb homonyms of high-image ability nouns were rated as significantly less imageable than their noun counterparts. A small number of words received significantly earlier or later age of acquisition ratings when the 20–40 years and 50–80 years age groups were compared. These tend to comprise words that have come to be used more frequently in recent years (either through technological advances or social change), or those that have fallen out of common usage. Regression analyses showed that although word length, familiarity, and concreteness make independent contributions to the age of acquisition measure, frequency and imageability are the most important predictors of rated age of acquisition.     

Distance effects in memory for sequences: evidence for estimation and scanning processes

The current study sought to uncover how temporal information is represented in our knowledge about routine events. In Experiment 1 we collected norming data on eight routines taken from Galambos (1983). In Experiment 2 participants were presented with two actions of varying distance from a routine and asked "Are the actions in the correct order?". We found that a number of variables interact with distance, including action position, routine familiarity, and experimental block. These data suggest that sometimes participants are faster when the actions are far apart in the routine, while at other times they are faster when actions are closer together, providing evidence for both distance and reverse-distance effects, respectively. A model is presented to help interpret these data in which temporal information for routine events is both: (1) coarsely coded, and processed by an estimation mechanism; and (2) represented serially, and processed by a scanning mechanism.     

Reginald L. Jones (1931-2005)

Reginald Lanier Jones (1931-2005), known as "Reg" or "Reggie" to many, was a tireless worker for social justice and equity within psychology and education. His career focused on children with special needs, the gifted, and especially the psychological experiences of the African American community. Many generations of Black psychologists owe their career success to his unswerving dedication, his insights as an elder, his acumen as a publisher, and his genuineness as a mentor and friend.     

Using Popular Films to Enhance Classroom Learning: The Good, the Bad, and the Interesting

ABSTRACT— Popular history films sometimes contain major historical inaccuracies. Two experiments investigated how watching such films influences people's ability to remember associated texts. Subjects watched film clips and studied texts about various historical topics. Whereas the texts contained only correct information, the film clips contained both correct information (consistent with the text) and misinformation (contradicted by the text). Before watching each clip, subjects received a specific warning, a general warning, or no warning about the misinformation. One week later, they returned for a cued-recall test about the texts. Watching a film clip increased correct recall of consistent information relative to recall of the same information when subjects did not see the clip. However, when the information in the film contradicted the text, subjects often (falsely) recalled misinformation from the film. The specific warning substantially reduced this misinformation effect. Teachers should use popular history films with caution and should warn students about major inaccuracies in the films.     

Self-relevance and wishful thinking: Facilitation and distortion in source monitoring

When making source attributions, people tend to attribute desirable statements to reliable sources and undesirable statements to unreliable sources, a phenomenon known as the wishful thinking effect (Gordon, Franklin, & Beck, 2005). In the present study, we examined the influence of wishful thinking on source monitoring for self-relevant information. On one hand, wishful thinking is expected, because self-relevant desires are presumably strong. However, self-relevance is known to confer a memory advantage and may thus provide protection from desire-based biases. In Experiment 1, source memory for self-relevant information was contrasted against source memory for information relevant to others and for neutral information. Results indicated that self-relevant information was affected by wishful thinking and was remembered more accurately than was other information. Experiment 2 showed that the magnitude of the self-relevant wishful thinking effect did not increase with a delay.
