Do nice guys--and gals--really finish last? The joint effects of sex and agreeableness on income

Sex and agreeableness were hypothesized to affect income, such that women and agreeable individuals were hypothesized to earn less than men and less agreeable individuals. Because agreeable men disconfirm (and disagreeable men confirm) conventional gender roles, agreeableness was expected to be more negatively related to income for men (i.e., the pay gap between agreeable men and agreeable women would be smaller than the gap between disagreeable men and disagreeable women). The hypotheses were supported across 4 studies. Study 1 confirmed the effects of sex and agreeableness on income and that the agreeableness-income relationship was significantly more negative for men than for women. Study 2 replicated these results, controlling for each of the other Big Five traits. Study 3 also replicated the interaction and explored explanations and paradoxes of the relationship. A 4th study, using an experimental design, yielded evidence for the argument that the joint effects of agreeableness and gender are due to backlash against agreeable men.     

IRTs of the ABCs: children's letter name acquisition

We examined the developmental sequence of letter name knowledge acquisition by children from 2 to five years of age. Data from 2 samples representing diverse regions, ethnicity, and socioeconomic backgrounds (ns = 1074 and 500) were analyzed using item response theory (IRT) and differential item functioning techniques. Results from factor analyses indicated that letter name knowledge represented a unidimensional skill; IRT results yielded significant differences between letters in both difficulty and discrimination. Results also indicated an approximate developmental sequence in letter name learning for the simplest and most challenging to learn letters--but with no clear sequence between these extremes. Findings also suggested that children were most likely to first learn their first initial. We discuss implications for assessment and instruction.     

Race/ethnicity and mental health in the first decade of the 21st century

Recent empirical studies on mental health generally report racial/ ethnic differences in depression rates but typically do not control for potential confounding by sample contextual variations in historical epoch, geographical location, and social demography. An empirical study of race/ethnicity differences in psychological distress is reported as an attempt to control these contexts by using a sample that is homogeneous in age, historical epoch, geography, and social demography (954 youth ages 18-19 living in a single, large urban community). No mean differences in psychological distress were observed among four racial/ethnic groups: Asians, African Americans, Latinos, and non-Hispanic Whites. A second analysis compared 17 different racial/ethnic groups defined in terms of family national origin. No differences in psychological distress were found among these groups. The findings are consistent with the view that race/ethnicity itself is not related to disparities in mental health.     

Development of parenting self‐efficacy in mothers of infants with high negative emotionality

Maternal parenting self‐efficacy (PSE) is a potential target for infant mental health interventions because it is associated with a number of positive outcomes for children and mothers. Understanding the development of maternal PSE under conditions of increased parenting stress, such as parenting an infant who is easily distressed and difficult to soothe, will contribute to providing more effective interventions. This study examines the development of maternal PSE in mothers of infants with high negative emotionality (NE). The Neonatal Behavioral Assessment Scale (NBAS; T. Brazelton, 1973 ) was administered twice to 111 infants to select a sample of irritable (n = 24) and nonirritable (n = 29) infants for a prospective study comparing the development of PSE in mothers of infants differing in neonatal NE. Consistent with our hypotheses and previous research, at 8 weeks' postpartum, mothers of irritable infants have significantly lower domain‐specific PSE than do mothers of nonirritable infants. Contrary to our predictions, mothers of irritable infants exhibit a significant increase in domain‐specific and domain‐general PSE from 8 to 16 weeks' postpartum. The implications of these results for infant mental health screening, infant mental health interventions, and research on self‐efficacy theory are discussed.     

Acquisition of a visual discrimination and reversal learning task by Labrador retrievers

Optimal cognitive ability is likely important for military working dogs (MWD) trained to detect explosives. An assessment of a dog’s ability to rapidly learn discriminations might be useful in the MWD selection process. In this study, visual discrimination and reversal tasks were used to assess cognitive performance in Labrador retrievers selected for an explosives detection program using a modified version of the Toronto General Testing Apparatus (TGTA), a system developed for assessing performance in a battery of neuropsychological tests in canines. The results of the current study revealed that, as previously found with beagles tested using the TGTA, Labrador retrievers (N = 16) readily acquired both tasks and learned the discrimination task significantly faster than the reversal task. The present study confirmed that the modified TGTA system is suitable for cognitive evaluations in Labrador retriever MWDs and can be used to further explore effects of sex, phenotype, age, and other factors in relation to canine cognition and learning, and may provide an additional screening tool for MWD selection.     

Wittgenstein and Friendship

In his article “It's a Wonderful Life,” Ronald Hall connects Wittgenstein's last words with Frank Capra's 1946 film. His analysis focuses on the concept of wonder, but he misses one of the most important aspects of both the film and Wittgenstein's last words: the significance of friendship. This is philosophically (and biographically) important because it raises questions about aspect‐seeing, friendship and everyday life. Wittgenstein's final words provide a striking example of the philosophical complexity of his life and work.     

The adaptation of the Affective Norms for English Words (ANEW) for Italian

We developed affective norms for 1,121 Italian words in order to provide researchers with a highly controlled tool for the study of verbal processing. This database was developed from translations of the 1,034 English words present in the Affective Norms for English Words (ANEW; Bradley & Lang, 1999) and from words taken from Italian semantic norms (Montefinese, Ambrosini, Fairfield, & Mammarella, Behavior Research Methods, 45, 440–461, 2013). Participants evaluated valence, arousal, and dominance using the Self-Assessment Manikin (SAM) in a Web survey procedure. Participants also provided evaluations of three subjective psycholinguistic indexes (familiarity, imageability, and concreteness), and five objective psycholinguistic indexes (e.g., word frequency) were also included in the resulting database in order to further characterize the Italian words. We obtained a typical quadratic relation between valence and arousal, in line with previous findings. We also tested the reliability of the present ANEW adaptation for Italian by comparing it to previous affective databases and performing split-half correlations for each variable. We found high split-half correlations within our sample and high correlations between our ratings and those of previous studies, confirming the validity of the adaptation of ANEW for Italian. This database of affective norms provides a tool for future research about the effects of emotion on human cognition.     

Brief Counseling for Alcohol Misuse Among Trauma Patients: Two Interventions and Influence of Baseline Use

This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors.
