Abstract
This study examined the role of global processing speed in mediating age increases in auditory memory span in 5- to 13-year-olds. Children were tested on measures of memory span, processing speed, single-word speech rate, phonological sensitivity, and vocabulary. Structural equation modeling supported a model in which age-associated increases in processing speed predicted the availability of long-term memory phonological representations for redintegration processes. The availability of long-term phonological representations, in turn, explained variance in memory span. Maximum speech rate did not predict independent variance in memory span.

Abstract
The basis of young children's performance of judgments of recency and frequency was investigated using a modified version of Huppert and Piercy's [Huppert, F.A., & Piercy, M. (1978). The role of trace strength in recency and frequency judgements by amnesic and control subjects. Quarterly Journal of Experimental Psychology, 30, 347–354] paradigm. Children aged 4 and 6 years viewed pictures of nameable objects presented either once or three times on either of two consecutive days. At test, children judged how recently (“today” versus “yesterday”) or frequently (once versus three times) each picture had been presented. Developmental improvements in performance were observed for judgments of recency and frequency. Evidence for responding based on episode-specific information was found for both age groups, showing that young children do not confuse recency of presentation with frequency of presentation. There was no evidence for a qualitative shift from reliance on trace strength to reliance on episode specific information across this age range.

Abstract
The hypothesis guiding this study stated that just world beliefs (i.e., the belief that the world is orderly and just) are primitive beliefs that lose their importance across age as they become replaced by more sophisticated forms of reasoning enabling individuals to handle a world that is neither orderly nor just. In addition, just world beliefs were thought to relate to perceptions of inequality and collectivism within society. In this study, a cross-sectional design was employed involving 235 secondary school pupils and 268 psychology students divided over six age groups with mean ages 12, 14, 16, 18, 20, and 22 years and older. They were presented with the Just World Beliefs Scale and the Individualism–Collectivism Scale. Outcomes revealed that general beliefs in a just world begin to loose their importance around the age of 12, followed by personal beliefs around the age of 16. Vertical collectivism related positively to general and personal just world beliefs showing that the experience of social ‘inequality’ plays an important role in the maintenance of such beliefs.

This article takes issue with the behavior-genetic analysis of parenting style presented by M. McGue, I. Elkins, B. Walden, and W. G. Iacono (2005). The author argues that the attribution of their findings to inherited genetic effects was without basis because McGue et al. never indicated how those genetic effects manifested themselves. Instead, McGue et al. neglected important, and inevitable, developmental effects that most developmental psychologists understand to influence parent and adolescent behavior. The author also suggests that there is great merit in adopting the approach of developmental systems theory in understanding McGue et al.'s findings in particular and all developmental phenomena in general.

Research on the cognitive deficits associated with attention-deficit/hyperactivity disorder has highlighted deficits in executive function in individuals with the disorder. This article suggests deconstructing the umbrella term “executive function” and focuses on one of its component processes: cognitive inhibition. Cognitive developmental psychology research suggests that component processes, such as cognitive inhibition, should be examined from a variety of approaches to fully appreciate patterns of competency and deficit. This article contrasts cognitive inhibition from behavioral inhibition and resistance to interference. Two types of cognitive inhibition, automatic and intentional, are proposed. Finally, suggestions for guiding research design are taken from the cognitive developmental psychology literature. These include studying very limited age ranges and conducting longitudinal research, investigating qualitative and quantitative differences in performance, examining the underlying processing and strategy differences between populations, and investigating multiple aspects of performance between populations.
Key Words: Executive function; cognitive inhibition; attention-deficit/hyperactivity disorder; cognitive development
