The Role of Paternal Age in the Prediction of Offspring Intelligence

Recent evidence suggests that paternal age at birth influences myriad developmental outcomes among children, but few studies have examined the possibility for father's age to influence children's intellectual development among a sample of high-risk families. The authors use data from the Fragile Families and Child Wellbeing Study to examine the association between paternal age at birth among 480 male and 449 female children's verbal IQ scores, as assessed with a version of the Peabody Picture Vocabulary Test at 9 years old. The nonlinear association between paternal age and children's verbal intelligence was also examined. Paternal age at birth appears to have a marginally significant nonlinear relationship with male children's verbal IQ scores, despite controlling for a number of possible confounders associated with both young and advanced paternal age.     

Ignored no more: Within‐Person variability enables better understanding of training transfer

The empirical findings from training transfer research rest on a rather static view of the transfer phenomenon, ignoring potential within‐person change in transfer over time. This study investigates within‐person variability in mastery goal orientation together with variability over time in the application of newly acquired knowledge and skills to the job context. Data from longitudinal surveys of trainees voluntarily attending statistical workshops revealed that trainees varied significantly in 2 characteristics of transfer trajectory: (a) initial attempts to transfer and (b) subsequent rate of change in transfer. Two affective learning outcomes showed differential relationships with transfer trajectories: Whereas posttraining self‐efficacy predicted initial attempt of transfer, motivation to transfer assessed at the end of training predicted subsequent rate of change in transfer. Furthermore, level and variability of trainees’ mastery orientation interacted to influence posttraining self‐efficacy and motivation to transfer, and subsequently transfer trajectories. Specifically, a trainee's mastery orientation level had stronger prediction of these outcomes when his/her mastery orientation distribution was less variable across situations. These findings highlight the importance of attending to within‐person variability in the study of training transfer by (a) considering training transfer as trajectories over time and (b) understanding trainee traits as frequency distributions.     

Validating presupposed versus focused text information

There is extensive evidence that readers continually validate discourse accuracy and congruence, but that they may also overlook conspicuous text contradictions. Validation may be thwarted when the inaccurate ideas are embedded sentence presuppositions. In four experiments, we examined readers’ validation of presupposed (“given”) versus new text information. Throughout, a critical concept, such as a truck versus a bus, was introduced early in a narrative. Later, a character stated or thought something about the truck, which therefore matched or mismatched its antecedent. Furthermore, truck was presented as either given or new information. Mismatch target reading times uniformly exceeded the matching ones by similar magnitudes for given and new concepts. We obtained this outcome using different grammatical constructions and with different antecedent–target distances. In Experiment 4, we examined only given critical ideas, but varied both their matching and the main verb’s factivity (e.g., factive know vs. nonfactive think). The Match × Factivity interaction closely resembled that previously observed for new target information (Singer, 2006). Thus, readers can successfully validate given target information. Although contemporary theories tend to emphasize either deficient or successful validation, both types of theory can accommodate the discourse and reader variables that may regulate validation.     

Referent Predictability is Affected by Syntactic Structure: Evidence from Chinese

This paper examines the effect of syntactic structures on referent predictability. Focusing on stimulus-experiencer (SE) verbs, we conducted two sentence-completion experiments in Chinese by contrasting SE verbs in three structures (active canonical, active ba, and passive). The results showed that although verb semantics and discourse coherence relations produce a strong referential biases, the stimulus referent is overall less likely to be rementioned in the active canonical structure than in the other two structures. The findings thus indicate that referent predictability is determined by not only semantic but also syntactic factors. We discuss the theoretical implications for the nature of referent predictability and its relationship with referent accessibility.

Plasticity and language: an example of the Baldwin effect?

In recent years, many scholars have suggested that the Baldwin effect may play an important role in the evolution of language. However, the Baldwin effect is a multifaceted and controversial process and the assessment of its connection with language is difficult without a formal model. This paper provides a first step in this direction. We examine a game-theoretic model of the interaction between plasticity (represented by Herrnstein reinforcement learning) and evolution in the context of a simple language game. Additionally, we describe three distinct aspects of the Baldwin effect: the Simpson–Baldwin effect, the Baldwin expediting effect and the Baldwin optimizing effect. We find that a simple model of the evolution of language lends theoretical plausibility to the existence of the Simpson–Baldwin and the Baldwin optimizing effects in this arena, but not the Baldwin expediting effect.     

Beliefs about God,Psychiatric Symptoms,and Evolutionary Psychiatry

The present study analyzed the association between specific beliefs about God and psychiatric symptoms among a representative sample of 1,306 U.S. adults. Three pairs of beliefs about God served as the independent variables: Close and Loving, Approving and Forgiving, and Creating and Judging. The dependent variables were measures of General Anxiety, Depression, Obsessive-Compulsion, Paranoid Ideation, Social Anxiety, and Somatization. As hypothesized, the strength of participants’ belief in a Close and Loving God had a significant salutary association with overall psychiatric symptomology, and the strength of this association was significantly stronger than that of the other beliefs, which had little association with the psychiatric symptomology. The authors discuss the findings in the context of evolutionary psychiatry, and the relevance of Evolutionary Threat Assessment Systems Theory in research on religious beliefs.     

Making Daddies into Fathers: Community-based Fatherhood Programs and the Construction of Masculinities for Low-income African American Men

In this analysis, we explore how low-income African American fathers build understandings of successful manhood in the context of community-based responsible fatherhood programs. Drawing on life history interviews with 75 men in Illinois and Indiana, we explore men’s attempts to fulfill normative expectations of fatherhood while living in communities with limited resources. We examine the efforts of community-based fatherhood programs to shape alternative African American masculinities through facilitation of personal turning points and “breaks with the past,” use of social support and institutional interventions, and the reframing of provision as a priority of successful fatherhood. We refer to Connell’s hegemonic masculinity framework (Connell in Masculinities, Polity Press, Cambridge, 1995) and discuss how both men and programs borrow from hegemonic and street masculinities to develop alternative approaches to paternal involvement for marginalized men.     

No role for lightness in the perception of black and white? Simultaneous contrast affects perceived skin tone, but not perceived race

Faces of individuals with African and European heritage (henceforth referred to as Black and White respectively) feature two major differences: those of skin tone and morphological characteristics. Although considerations of perceived race are important to various psychological subdisciplines, to date the relative influence of morphological versus photometric characteristics has not been investigated. We attempted to influence the perceived racial typicality of a central target face by manipulating perceived skin tone using the well-known lightness contrast illusion. As expected, ratings of skin tone were influenced by surround faces, yet ratings of perceived racial typicality were not, suggesting a dissociation between the two judgments. Surprisingly, skin tone contributes little to perceived race, leaving facial morphology as the dominant cue. These results may shed light on failures to find effects of racial typicality in studies of prejudice where judgments were based on photographs with altered skin tone alone.
