Measuring Sensitivity to Conflicts of Interest: A Preliminary Test of Method

This study presents and develops test methods for assessing sensitivity to conflict of interest (COIsen). We are aware of no study assessing COIsen, but note that some popular methods for assessing ethical sensitivity and related constructs (which include COIsen) are flawed in that their presentation of stimulus material to subjects actually guides subjects to attend to ethical (or related) issues. The method tested here was designed to avoid this flaw. Using adaptations of two existing cases, a quota sample of 12 students was interviewed. Our method used funnel-sequenced, open-ended interviews that were audiotaped and transcribed, then subjected to a form of cognitive mapping. These maps revealed the presence of “indicators” of COIsen. We found that COIsen can be measured and that the global COIsen score generated by our method is able to reveal much variation across subjects, making it a worthwhile candidate for further consideration.     

The development of stranger fear in infancy and toddlerhood: normative development,individual differences,antecedents, and outcomes

Despite implications that stranger fear is an important aspect of developing behavioral inhibition, a known risk factor for anxiety, normative and atypical developmental trajectories of stranger fear across infancy and toddlerhood remain understudied. We used a large, longitudinal data set (N = 1285) including multi‐trait, multi‐method assessments of temperament to examine the normative course of development for stranger fear and to explore the possibility that individual differences exist in trajectories of stranger fear development between 6 and 36 months of age. A latent class growth analysis suggested four different trajectories of stranger fear during this period. Stable, high levels of stranger fear over time were associated with poorer RSA suppression at 6 months of age. Rates of concordance in trajectory‐based class membership for identical (monozygotic) and fraternal (dizygotic) twins, along with associations between atypical stranger fear development and greater anxiety‐related maternal characteristics, suggested that individual differences in developmental trajectories of stranger fear may be heritable. Importantly, trajectories of stranger fear during infancy and toddlerhood were linked to individual differences in behavioral inhibition, with chronically high levels of stranger fear and sharp increases in stranger fear over time related to greater levels of inhibition than other developmental trajectories.     

Infants hierarchically organize memory representations

Throughout development, working memory is subject to capacity limits that severely constrain short‐term storage. However, adults can massively expand the total amount of remembered information by grouping items into chunks. Although infants also have been shown to chunk objects in memory, little is known regarding the limits of this ability. In particular, it remains unknown whether infants can create more complex memory hierarchies, binding representations of chunks into still larger chunks in recursive fashion. Here we tested the limits of early chunking, first measuring the number of items infants can bind into a single chunk and the number of chunks infants can maintain concurrently, and then, critically, whether infants can embed chunked representations into larger units. We tested 14‐month‐old infants' memory for hidden objects using a manual search task in which we manipulated memory load (the number of objects infants saw hidden) and the chunking cues provided. We found that infants are limited in the number of items they can chunk and in the number of chunks they can remember. However, we also found that infants can bind representations of chunks into ‘superchunks’. These results suggest that hierarchically organizing information strongly affects working memory, starting in infancy.     

Causal attributions from adolescence through adulthood

Attributional reasoning for events varying on level of informational ambiguity and context (relationship, achievement) were examined from adolescence through older adulthood. Participants rated the degree to which a cause of an event was a function of the primary character, situation, or a combination of these; wrote essays assessing underlying reasons for attributions; and responded to ego level, attributional style, and intolerance for ambiguity questionnaires. Older age groups made more interactive (relativistic) attributional ratings than did younger age groups for ambiguous events. Compared to adult and middle-aged adults, older women demonstrated a drop in dialectical attributional reasoning as assessed by the essays. Ego level, tolerance for ambiguity, and verbal ability predicted more dialectical attributional reasoning above and beyond the effects of age.     

Dyadic Models for the Study of Health

Dyadic designs have been used in health research to investigate intra‐ and inter‐personal mechanisms of health and well‐being in various types of dyads, including parent–child dyads, siblings, friends, and romantic partners. Although a growing number of researchers are designing studies that capture the interdependent complexities of relationships, many still need more information on how to analyze the data in a way that maximizes its value. Therefore, the purpose of this review paper is twofold: (1) to address some of the ways in which dyadic data analysis is being used in current health research, with an emphasis on research that has employed the Actor‐Partner Interdependence Model, and (2) to propose and explain various methodological and substantive considerations that researchers should consider when using dyadic data analysis in their own research.     

Structural analysis of the intension and extension of semantic concepts

The present studies examined the nature of visuo-spatial working memory development using conventional visual span and spatial span measures. Children aged between 6 and 13 years and adults aged 18-38 years were employed as participants. In Study 1, visual span, spatial span, articulation rate, and verbal fluency competencies were measured. In Study 2, visual span and spatial span maintenance was subject to five interference formats: nil, speech articulation, verbal fluency, visual masking, and spatial tapping. Distinct developmental rates were found for the two span tasks, which in the older children were correlated with the verbal fluency measure. Study 2 provided experimental evidence of the contribution of executive and spatial processes to spatial and to visual span maintenance. The results are interpreted as indicating that these memory span procedures make complex demands upon the visuo-spatial working memory architecture and consequently a precise identification of the process that actually develop is compromised. It is suggested that a componential approach where tasks are constructed to tap specific working memory components would afford a more accurate understanding of the development of these processes.     

Who? What? When? Using a timeline technique to facilitate recall of a complex event

Accurately recalling a complex multi-actor incident presents witnesses with a cognitively demanding retrieval task. Given the important role played by temporal context in the retrieval process, the current research tests an innovative timeline technique to elicit information about multiple perpetrators and their actions. Adopting a standard mock witness paradigm, participants were required to provide an account of a witnessed event. In Experiment 1, the timeline technique facilitated the reporting of more correct details than a free recall, immediately and at a two-week retention interval, at no cost to accuracy. Accounts provided using the timeline technique included more correct information about perpetrator specific actions and fewer sequencing errors. Experiment 2 examined which mnemonic components of the timeline technique might account for these effects. The benefits of exploiting memory organization and reducing cognitive constraints on information flow are likely to underpin the apparent timeline advantage.     

Family, Community, and Motherhood: Caring for Fatherless Children in the Jewish Community of Thirteenth-Century Perpignan

This article investigates the guardianship of fatherless children (orphans) in one of the most important Jewish communities of the thirteenth-century realms of Aragon, the aljama of the town of Perpignan. After reviewing some ideals of Solomon ben Abraham ibn Adret of Barcelona, as expressed in his responsa, the article focuses on documents of practice. This documentary basis includes royal charters, Latin wills of Jewish testators, and 148 unedited transactions generated by eighteen panels of guardians between 1266 and 1286, described in an analytical table at the end of the article. The practical evidence reveals that guardians usually served as a group, panels comprised close relatives of the wards and men who were distinguished in their community through official service. Case studies expose the dynamics within these panels and establish that the orphans' widowed mother usually acted as the group's leader. A comparison with her Christian counterpart places the rights and responsibilities of the Jewish widowed mother guardian into relief. Although not autonomous, Jewish widowed guardians were highly effective caretakers of their fatherless children. The idealized view of the Jewish widow held by her medieval contemporaries as helpless and in need of special care from the men of her community enabled already capable widows to benefit from the financial aid of community leaders who otherwise might not have been so keen to foster these women's legal and financial agency.
