Mental multiplication: Nothing but the facts?

Current models of adult arithmetic performance assume that representation includes only facts and procedures. However, other kinds of representations such as an analog scale or sets of number multiples might be useful in a variety of multiplication-related tasks. Introducing the practice transfer paradigm, we demonstrate that associations between distinct representational structures can be detected via cross-task transfer, provided that initial performance is retrieval based. Results support the predictions of the integrated-structures model of multiplication knowledge. Implications for well-established item differences such as the problem-size effect are addressed, and the question of how integration occurs is considered.     

The Impact of Necessity and Sufficiency in The Wason Four-Card Selection Task

Performance in the Wason card selection task is often improved given thematic content. Such content effects have been considered evidence against human rationality. We propose that the role of content lies in specifying premises underlying "if P, then Q" rules. Unlike thematic rules, abstract conditional rules do not explicitly provide material interpretation (P is a sufficient but not necessarily a necessary condition for Q), resulting in nonnormative responses. When necessity–sufficiency relations were explicated, normative responses were elicited and effects of other logically irrelevant components disappeared. The results suggest that content effects are compatible with human rationality.     

What’s in a name? Lexical knowledge drives infants’ visual preferences in the absence of referential input

Seventeen-month-old infants were presented with pairs of images, in silence or with the non-directive auditory stimulus ‘look!’. The images had been chosen so that one image depicted an item whose name was known to the infant, and the other image depicted an image whose name was not known to the infant. Infants looked longer at images for which they had names than at images for which they did not have names, despite the absence of any referential input. The experiment controlled for the familiarity of the objects depicted: in each trial, image pairs presented to infants had previously been judged by caregivers to be of roughly equal familiarity. From a theoretical perspective, the results indicate that objects with names are of intrinsic interest to the infant. The possible causal direction for this linkage is discussed and it is concluded that the results are consistent with Whorfian linguistic determinism, although other construals are possible. From a methodological perspective, the results have implications for the use of preferential looking as an index of early word comprehension.     

Partner aggression in high-risk families from birth to age 3 years: associations with harsh parenting and child maladjustment

Aggression between partners represents a potential guiding force in family dynamics. However, research examining the influence of partner aggression (physically and psychologically aggressive acts by both partners) on harsh parenting and young child adjustment has been limited by a frequent focus on low-risk samples and by the examination of partner aggression at a single time point. Especially in the context of multiple risk factors and around transitions such as childbirth, partner aggression might be better understood as a dynamic process. In the present study, longitudinal trajectories of partner aggression from birth to age 3 years in a large, high-risk, and ethnically diverse sample (N = 461) were examined. Specific risk factors were tested as predictors of aggression over time, and the longitudinal effects of partner aggression on maternal harsh parenting and child maladjustment were examined. Partner aggression decreased over time, with higher maternal depression and lower maternal age predicting greater decreases in partner aggression. While taking into account contextual and psychosocial risk factors, higher partner aggression measured at birth and a smaller decrease over time independently predicted higher levels of maternal harsh parenting at age 3 years. Initial level of partner aggression and change over time predicted child maladjustment indirectly (via maternal harsh parenting). The implications of understanding change in partner aggression over time as a path to harsh parenting and young children's maladjustment in the context of multiple risk factors are discussed.     

Gender Differences in the Social Functioning of Adolescents with Inflammatory Bowel Disease

Inflammatory bowel disease (IBD) has been associated with social difficulties. Boys with IBD may have increased risk for social problems due to delayed growth and puberty, but gender differences in social functioning have not been investigated. This study examined gender differences in multiple areas of social functioning for adolescents with IBD compared to healthy adolescents. Participants were 92 adolescents 11-17?years (50 with IBD, 42 healthy) and parents who completed questionnaires assessing social functioning. IBD was associated with poorer social functioning in the areas of social competence and social problems. Boys with IBD had worse social competence, with no gender differences for social problems. Gender predicted the use of social contact as a coping strategy, but no significant group differences were found for other areas of social functioning. Adolescents with IBD experience significant social difficulties in some areas, and boys are at risk for poor social competence. However, previously reported social difficulties may not extend to all areas of social functioning.     

Early Career Boot Camp: A Novel Mechanism for Enhancing Early Career Development for Psychologists in Academic Healthcare

The purpose of this article is to describe a pilot mentoring program for Early Career Psychologists (ECPs) working in Academic Health Centers (AHCs) and synthesize the lessons learned to contribute to future ECP and AHC career development training programs. The authors describe an early career development model, named the Early Career Boot Camp. This intensive experience was conducted as a workshop meant to build a supportive network and to provide mentorship and survival tools for working in AHCs. Four major components were addressed: professional effectiveness, clinical supervision, strategic career planning, and academic research. Nineteen attendees who were currently less than 5 years post completion of doctoral graduate programs in psychology participated in the program. The majority of boot camp components were rated as good to excellent, with no component receiving below average ratings. Of the components offered within the boot camp, mentoring and research activities were rated the strongest, followed by educational activities, challenges in AHCS, and promotion and tenure. The article describes the purpose, development, implementation, and assessment of the program in detail in an effort to provide an established outline for future organizations to utilize when mentoring ECPs.     

Class matters: 12‐month‐olds’ word–object associations privilege content over function words

A fundamental step in learning words is the development of an association between a sound pattern and an element in the environment. Here we explore the nature of this associative ability in 12‐month‐olds, examining whether it is constrained to privilege particular word forms over others. Forty‐eight infants were presented with sets of novel English content‐like word–object pairings (e.g. fep) or novel English function‐like word–object (e.g. iv) pairings until they habituated. Results indicated that infants associated novel content‐like words, but not the novel function‐like words, with novel objects. These results demonstrate that the mechanism with which basic word–object associations are formed is remarkably sophisticated by the onset of productive language. That is, mere associative pairings are not sufficient to form mappings. Rather the system requires well‐formed noun‐like words to co‐occur with objects in order for the linkages to arise.
