Investigating the relationship between working memory and emotion regulation in mothers

Recent work suggests that executive functions, specifically working memory, may facilitate emotion regulation (ER). Here we examined whether measures of visuospatial working memory and verbal working memory relate to ER in a group of recent mothers. We found that while visuospatial working memory was associated with, and predictive of, self-reported measures of ER and emotion dysregulation—verbal working memory was correlated to only one dimension of emotion dysregulation. These findings suggest that working memory may play a unique role in everyday regulatory functioning. We frame our results in terms of the broader implications they may have for the potential role of executive functioning in parenting.     

Morpho-orthographic segmentation without semantics

Masked priming studies have repeatedly provided evidence for a form-based morpho-orthographic segmentation mechanism that blindly decomposes any word with the mere appearance of morphological complexity (e.g., corn + er). This account has been called into question by Baayen et al. Psychological Review, 118, 438–482 (2011), who pointed out that the prime words previously tested in the morpho-orthographic condition vary in the extent to which the suffix conveys regular meaning. In the present study, we investigated whether evidence for morpho-orthographic segmentation can be obtained with a set of tightly controlled prime words that are entirely semantically opaque. Using a visual lexical decision task, we compared priming from truly suffixed primes (hunter-HUNT), completely opaque pseudo-suffixed primes (corner-CORN), and non-suffixed primes (cashew-CASH). The results show comparable magnitudes of priming for the truly suffixed and pseudo-suffixed primes, and no priming from non-suffixed primes, and therefore provide further important evidence in support of morpho-orthographic segmentation processes operating in the absence of any possible role for semantics.     

Number concepts for the concept empiricist

Dove (2009) and Machery (2007) both argue that recent findings about the nature of numerical representation present problems for Concept Empiricism (CE). I shall argue that, whilst this evidence does challenge certain versions of CE, such as Prinz (2002), it needn’t be seen as problematic to the general CE approach. Recent research can arguably be seen to support a CE account of number concepts. Neurological and behavioral evidence suggests that systems involved in the perception of numerical properties are also implicated in numerical cognition. Furthermore, the discovery of associations between spatial and numerical representations also lends independent support to a CE approach. Although these findings support CE in general, certain versions of the theory may need revising in order to accommodate them. In particular, it may be necessary to either jettison Prinz's (2002) Modal Specificity Hypothesis or to revise one’s method for individuating modal representational formats.     

Wright's Argument from Neutrality

In the first chapter of his book Truth and Objectivity (1992), Crispin Wright puts forward what he regards as 'a fundamental and decisive objection' to deflationism about truth (p. 21). His objection proceeds by an argument to the conclusion that truth and warranted assertibility coincide in normative force and potentially diverge in extension ( I call this the 'argument from neutrality'). This argument has already received some attention. However, I do not believe that it has been fully understood yet. In this short paper, I shall assess the cogency of Wright's objection in some detail. My agenda is as follows. First, I give what I believe to be an adequate rendering of the objection. Secondly, I reveal the real force of the neutrality argument and say thirdly why it does not, as Wright thinks, refute deflationism. Finally, I argue that Wright's insistence that truth is a 'substantial property' is uncongenial to the overall project of his book.     

Strategy Discovery as a Competitive Negotiation between Metacognitive and Associative Mechanisms

Both metacognitive and associative models have been proposed to account for children's strategy discovery and use. Models based on only metacognitive or only associative mechanisms cannot entirely account for the observed mix of variability and constraint revealed by recent microgenetic studies of children's strategy change. We propose a new approach where metacognitive and associative mechanisms interact in a competitive negotiation. This approach provides the flexibility to model the observed variability and constraint.     

Gender Differences in the Organization of Guilt and Shame

Lewis [(1971) Shame in Guilt in Neurosis, New York: International Universities Press] argues that guilt and shame represent distinct modes of perceiving and experiencing information about the self that are congruent with gender-linked differences in socialization. We tested predictions from Lewis' model that shame-proneness in adult White females (n = 102), but guilt-proneness in adult White males (n = 99), would account for a substantial proportion of the variance in measures assessing their characteristic use of defense mechanisms and endorsement of gender roles. Certain results confirmed Lewis' broader claim that guilt for men, but shame for women, were predominant modes of organizing information about the self. Other results did not support certain specific predictions made by Lewis or they provided only equivocal support (e.g., in men, the joint positive relationship of guilt-proneness to communal orientations but its negative relationship to externalization). Similar discrepant findings emerged for females' construal of guilt, which also related positively to internalization. Although shame-proneness did emerge as the principal emotion variable for females, it was linked to both internalization and externalization. Lewis' model is reconsidered in light of recent empirical findings and the need to conduct more on-line investigations of transgression-emotion induction-emotion reduction cycles.     

Contribution of ADHD symptoms to substance problems and delinquency in conduct-disordered adolescents

We examined adolescents with conduct disorder (CD) and substance problems to determine if those with attention deficit hyperactivity disorder (ADHD) symptomatology had more severe delinquency and substance involvement. ADHD symptomatology was assessed in two ways: (1) by self-reports using the Diagnostic Interview Schedule for Children (DISC) and (2) by use of DISC plus reports of others (parents, program staff, and program teacher). We divided boys into three ADHD groups based on DISC: those who met criteria, those who reported at least eight current symptoms, and those who reported fewer than eight symptoms. We also divided the same boys into two groups: those with reports of ADHD by two or more sources and those without this multisource ADHD. Examining these definitions of ADHD revealed that boys with either self- or multisource ADHD had more CD symptoms, earlier age of CD onset, more substance dependence diagnoses, and more comorbid depression and anxiety.This investigation was supported by the National Institute on Drug Abuse Grant No. DAO6941.
