The relationship between short‐term memory and working memory: Complex span made simple?

This experiment addresses the question of what makes a working memory measure a good predictor of higher‐level abilities. Verbal and visuospatial processing episodes were interleaved with distinct verbal and visuospatial storage episodes to form four complex span tasks. Although these measures were reliable predictors of reading and mathematics ability in children, they were no more predictive of these abilities than corresponding simple span tasks involving storage alone. However, when individual differences in storage ability and processing capacity were controlled for, residual variance in complex span performance was related to academic ability in some cases. These findings indicate that complex span tasks are multiply determined, and that differences in task structure can dramatically influence the relative importance of these multiple constraints and the predictive power of a complex span measure.     

Children's memory for complex autobiographical events: Does spacing of repeated instances matter?

Often, when children testify in court they do so as victims of a repeated offence and must report details of an instance of the offence. One factor that may influence children's ability to succeed in this task concerns the temporal distance between presentations of the repeated event. Indeed, there is a substantial amount of literature on the “spacing effect” that suggests this may be the case. In the current research, we examined the effect of temporal spacing on memory reports for complex autobiographical events. Children participated in one or four play sessions presented at different intervals. Later, children were suggestively questioned, and then participated in a memory test. Superior recall of distributed events (a spacing effect) was found when the delay to test was 1?day (Experiment 1) but there was little evidence for a spacing effect when the delay was 1 week (Experiment 2). Implications for understanding children's recall of repeated autobiographical events are discussed.     

Speech‐evoked auditory brainstem responses reflect familial and cognitive influences

Cortical function and related cognitive, language, and communication skills are genetically influenced. The auditory brainstem response to speech is linked to language skill, reading ability, cognitive skills, and speech‐in‐noise perception; however, the impact of shared genetic and environmental factors on the response has not been investigated. We assessed auditory brainstem responses to speech presented in quiet and background noise from (1) 23 pairs of same sex, same learning diagnosis siblings (Siblings), (2) 23 unrelated children matched on age, sex, IQ, and reading ability to one of the siblings (Reading‐Matched), and (3) 22 pairs of unrelated children matched on age and sex but not on reading ability to the same sibling (Age/Sex‐Matched). By quantifying response similarity as the intersubject response‐to‐response correlation for sibling pairs, reading‐matched pairs, and age‐ and sex‐matched pairs, we found that siblings had more similar responses than age‐ and sex‐matched pairs and reading‐matched pairs. Similarity of responses between siblings was as high as the similarity of responses collected from an individual over the course of the recording session. Responses from unrelated children matched on reading were more similar than responses from unrelated children matched only on age and sex, supporting previous data linking variations in auditory brainstem activity with variations in reading ability. These results suggest that auditory brainstem function can be influenced by siblingship and auditory‐based communication skills such as reading, motivating the use of speech‐evoked auditory brainstem responses for assessing risk of reading and communication impairments in family members.     

Religious orientation and its association with personality,schizotypal traits and manic-depressive experiences

A total of 180 respondents completed the Eysenck Personality Questionnaire, Claridge's STQ, Thalbourne's Manic-Depression scales and the Batson and Ventis Religious Life Inventory (RLI). The RLI was used to yield scores for external, internal and quest dimensions of religiosity. Principal Component Analysis showed the quest dimension to be separate from external and internal religion, which loaded together on one factor. It was found that when the personality and schizotypal trait measures were entered together to predict scores on religiosity, psychoticism emerged as the only predictor of external and internal religiosity, where as schizotypal traits emerged as the only predictor of religious quest.     

Developmental Continuity in Teleo-Functional Explanation: Reasoning about Nature Among Romanian Romani Adults

Teleo-functional explanations account for objects in terms of purpose, helping us understand objects such as pencils (for writing) and body parts such as ears (for hearing). Western-educated adults restrict teleo-functional attributions to artifact, biological, and behavioral phenomena, considering such explanations less appropriate for nonliving natural entities. In contrast, children extend explanations of purpose to the nonliving natural domain. This cross-cultural study explores whether apparent restrictions in“promiscuous teleology” occur as a function of age and development, generally, or scientific literacy, more specifically. Using methodology from Kelemen (1999b Kelemen , D. ( 1999b ). Why are rocks pointy? Children's preference for teleo-functional explanations of the natural world . Developmental Psychology , 35 , 1440 – 1453 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), two groups of adult Romanian Roma from the same community selected explanations for properties of biological and nonbiological natural entities; one group had little or no science training, the other was formally schooled. Compared to their schooled peers and to Western-educated American adults, nonschooled Romani adults were more likely to endorse purpose-based explanations of nonbiological natural entities. Findings challenge assumptions of fundamental conceptual discontinuities between children and adults.     

Applicants' and Employees' Reactions to Corporate Social Responsibility: The Moderating Effects of First‐Party Justice Perceptions and Moral Identity

This research explored individuals’ reactions to perceived corporate social responsibility (CSR) using a multimotive framework. In 2 studies, the authors explored the boundary conditions of CSR effects among job applicants and internal employees. A scenario‐based experiment (N = 81) showed that the effect of CSR perceptions on job applicants’ job pursuit intentions was mitigated by applicants’ first‐party justice experiences, whereas it was amplified by their moral identity (Study 1). Survey data from 245 full‐time employees (Study 2) further supported the interactive effects revealed in Study 1. Specifically, first‐party justice perceptions attenuated the positive relationship between employees’ CSR perceptions and their organizational citizenship behavior (OCB); and the relationship between CSR perceptions and OCB was more pronounced among employees high (versus low) in moral identity. Our findings bridge the CSR and organizational justice literatures, and reveal that the effects of individuals’ CSR perceptions are more complicated than previously thought. The findings shed light on micro (employee)‐level CSR phenomena and offer implications for both research and practice.     

Mother-child discourse in two contexts: links with child temperament, attachment security, and socioemotional competence

The goal of this study was to examine whether attachment security and child temperament predicted differences in the elaboration and emotional content of mother-child discourse in 2 contexts and whether those differences were related to a child's socioemotional development. Fifty-one preschool children and their mothers were videotaped reading a storybook and discussing the child's previous behavior. These conversations were coded for maternal elaboration and emotional content. Mothers also completed reports of child temperament, attachment security, and social behavior. Children completed measures of emotional understanding, behavioral internalization, and representations of relationships. The findings suggested that both aspects of mother-child discourse were related to attachment, temperament, and socioemotional competence, although the findings varied depending on the context of the discourse.     

Can semantic relatedness explain the enhancement of memory for emotional words?

Memory for emotional items is often better than memory for neutral items. In three experiments, we examined whether this typical finding is due to the higher semantic relatedness inherent to emotional items, a confound in previous studies. We also controlled for other possible confounding variables, such as imagery. In Experiments 1 and 2, participants encoded lists of emotional and categorized neutral words equivalent in semantic relatedness, as well as lists of random neutral words with lower semantic relatedness. In Experiment 3, the lists were mixed, containing words from all the conditions. Surprise free recall was tested after a 40- to 55-min retention interval. Free recall of emotional words was better than that of random neutral words, replicating the classic effect. Importantly, categorized words were recalled better than random neutral words, and not worse than emotional words. These results emphasize the important role of semantic relatedness in the classic effect and suggest that organizational processes operate alongside arousal-related ones to enhance memory for emotional material.     

Depressive personality disorder: rates of comorbidity with personality disorders and relations to the five-factor model of personality

Depressive personality disorder (DPD) is listed in the DSM-IV as one of the "Disorders for Further Study." In this investigation we examined (1) the rates of comorbidity of DPD with the 10 personality disorders (PDs) in the main text of DSM-IV, and (2) the convergent and discriminant validity of DPD in its relation to the 30 facet traits of the Five-Factor Model of personality (FFM). One hundred and sixty-nine participants with psychiatric diagnoses were interviewed with the Structured Clinical Interview for DSM-IV Personality Disorders Questionnaire (SCID-II) and completed the Revised NEO Personality Inventory (NEO PI-R). A total of 26 (15%) of the participants met diagnostic criteria for at least one of the 10 main text PDs, and 15 (9%) met criteria for DPD. Of those who met criteria for DPD, 10 (59%) of the participants also met criteria for one or more of the 10 main text PDs. Regression analyses indicated a four-facet trait set derived from the NEO PI-R thought to be uniquely associated with DPD accounted for a significant amount of variance in DPD SCID-II PD scores and was significantly larger for DPD than it was for the 9 of the 10 main text PDs; the sole exception was for avoidant PD. Diagnostically, DPD overlaps significantly with other PDs but is distinguishable in its unique relation with traits from the FFM.
