Making decisions with the future in mind: Developmental and comparative identification of mental time travel

Mechanisms that produce behavior which increase future survival chances provide an adaptive advantage. The flexibility of human behavior is at least partly the result of one such mechanism, our ability to travel mentally in time and entertain potential future scenarios. We can study mental time travel in children using language. Current results suggest that key developments occur between the ages of three to five. However, linguistic performance can be misleading as language itself is developing. We therefore advocate the use of methodologies that focus on future-oriented action. Mental time travel required profound changes in humans' motivational system, so that current behavior could be directed to secure not just present, but individually anticipated future needs. Such behavior should be distinguishable from behavior based on current drives, or on other mechanisms. We propose an experimental paradigm that provides subjects with an opportunity to act now to satisfy a need not currently experienced. This approach may be used to assess mental time travel in nonhuman animals. We conclude by describing a preliminary study employing an adaptation of this paradigm for children. (c) 2005 Elsevier Inc.

Young children's understanding of oddity: reducing complexity by simple oddity and "most different" strategies

Children aged between 3 and 7 years were taught simple and dimension-abstracted oddity discrimination using learning-set training techniques, in which isomorphic problems with varying content were presented with verbal explanation and feedback. Following the training phase, simple oddity (SO), dimension-abstracted oddity with one or two irrelevant dimensions, and non-oddity (NO) tasks were presented (without feedback) to determine the basis of solution. Although dimension-abstracted oddity requires discrimination based on a stimulus that is different from the others, which are all the same as each other on the relevant dimension, this was not the major strategy. The data were more consistent with use of a simple oddity strategy by 3- to 4-year-olds, and a most different strategy by 6- to 7-year-olds. These strategies are interpreted as reducing task complexity. (C) 2002 Elsevier Science Inc. All rights reserved.

Jung and the dreaming: Analytical psychology's encounters with Aboriginal culture

This article reviews some contributions of the Jungian analytic tradition to indigenous ethnopsychiatric thought in Australia. The authors review Jung's writings on Aboriginal culture, then describe some of their own fieldwork findings. Acknowledging that the contemporary post-Jungian tradition is pluralist, they propose a notion of 'Jungian sensibility.' They discuss some of the ways in which the Jungian sensibility might contribute positively to Aboriginal mental health, with especial reference to theories of subjectivity, and note that some Aboriginal people find the Jungian world-view very compatible with the Aboriginal one.

Optimism health-related hardiness and well-being among older Australian women

This article examines whether optimism and health-related hardiness contribute to health and well-being among older women. Positive psychological characteristics, including optimism and health-related hardiness, are correlated with good self-rated health, but these variables are all affected by socioeconomic status, social support, physical illness and access to services. Using data from 9501 Australian women aged 73 to 78, we show that optimism and health-related hardiness explain a significant proportion of variance in all subscales of the SF-36, and in stress, even after these confounders are taken into account. The data, although cross-sectional, suggest that positive personal characteristics may contribute to well-being.

Attentional bias toward fear-related stimuli: An investigation with nonselected children and adults and children with anxiety disorders

Research investigating anxiety-related attentional bias for emotional information in anxious and nonanxious children has been equivocal with regard to whether a bias for fear-related stimuli is unique to anxious children or is common to children in general. Moreover, recent cognitive theories have proposed that an attentional bias for objectively threatening stimuli may be common to all individuals, with this effect enhanced in anxious individuals. The current study investigated whether an attentional bias toward fear-related pictures could be found in nonselected children (n = 105) and adults (n = 47) and whether a sample of clinically anxious children (n = 23) displayed an attentional bias for fear-related pictures over and above that expected for nonselected children. Participants completed a dot-probe task that employed fear-related, neutral, and pleasant pictures. As expected, both adults and children showed a stronger attentional bias toward fear-related pictures than toward pleasant pictures. Consistent with some findings in the childhood domain, the extent of the attentional bias toward fear-related pictures did not differ significantly between anxious children and nonselected children. However, compared with nonselected children, anxious children showed a stronger attentional bias overall toward affective picture stimuli. (C) 2004 Elsevier Inc. All rights reserved.

Global processing speed as a mediator of developmental changes in children's auditory memory span

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. (c) 2005 Elsevier Inc.

Recalling yesterday and predicting tomorrow

Three-, 4- and 5-year-old children were asked to report something that they did do yesterday and something that they were going to do tomorrow. They were also asked to recall events that had not occurred yesterday, and predict events that would not occur tomorrow. In two studies these simple questions revealed striking age differences in the ability to report personal events from the past and the future. Only a minority of 3-year-olds but a majority of the older children were able to appropriately answer these questions. These findings substantiate the proposal that the ability to recall past events and the ability to predict future events (i.e., mental time travel), emerge in tandem between the ages of 3 and 5 years.

Grammatical sensitivity: Its origins and potential contribution to early word reading skill

A three-phase longitudinal study examined the origins of grammatical sensitivity and its usefulness as a predictor of early word-level reading. At about 4 years of age, children were given a range of language and cognitive tests. One year later, the children were given a further series of language and cognitive tests, this time including grammatical sensitivity, phonological sensitivity, and nonword repetition. Another year later, word-level reading achievement was assessed. Overall, grammatical sensitivity and phonological sensitivity were more firmly grounded in earlier language ability than in cognitive ability. Phonological sensitivity and nonword repetition showed reliable predictive associations with subsequent word reading skills. Grammatical sensitivity did not. (c) 2005 Elsevier Inc.

Testing the protracted lexical restructuring hypothesis: The effects of position and acoustic-phonetic clarity on sensitivity to mispronunciations in children and adults

Although developmental increases in the size of the position effect within a mispronunciation detection task have been interpreted as consistent with a view of the lexical restructuring process as protracted, the position effect itself might not be reliable. The current research examined the effects of position and clarity of acoustic-phonetic information on sensitivity to mispronounced onsets in 5- and 6-year-olds and adults. Both children and adults showed a position effect only when mispronunciations also differed in the amount of relevant acoustic-phonetic information. Adults' sensitivity to mispronounced second-syllable onsets also reflected the availability of acoustic-phonetic information. The implications of these findings are discussed in relation to the lexical restructuring hypothesis. (c) 2006 Elsevier Inc. All rights reserved.

Being fit and looking healthy: Young women's and men's constructions of health and fitness

We drew on Foucault's notion of 'practices of the self' to examine how young people take up, negotiate, and resist the imperatives of a public health discourse concerned with the relationships between health, fitness, and the body. We did this through a discussion of the ways young women and men talk about their own and others' bodies, in the context of a number of in-depth interviews conducted for the Life Activity Project, a study of the place and meaning of physical activity in young people's lives, funded by an Australian Research Council Grant. We found that the young women and men in the study engaged the health/fitness discourse very differently: for the young men, health conflated with fitness as an embodied capacity to do physical work; and for the young women, health was a much more difficult and complex project associated with managing and monitoring practices associated with eating and exercise to maintain an 'appropriate' body shape.

Hostile sexism and rape proclivity amongst men

In the current study, we examined the influence of victim type and hostile sexism on men's judgments about an acquaintance rape victim and their self-reported acquaintance rape proclivity. It was predicted that hostile sexism would predict self-reported rape proclivity, but that this relationship would be moderated by victim type. Specifically, it was predicted that participants would report greater proclivity in relation to a victim who appeared not to adhere to traditional gender stereotypes than to a victim who appeared to adhere to such stereotypes. Further, in line with D. Abrams, G. T. Viki, B. Masser, and G. Bohner (2003), it was predicted that the relationship between hostile sexism and rape proclivity would be mediated by perceptions of token resistance by the victim. Results partially supported the hypotheses. Hostile sexism was positively related to rape proclivity, but victim type was not found to moderate the relationship. In addition, perceptions of token resistance were found to mediate the hostile sexism and rape proclivity relationship. The results suggest that, at least in terms of rape proclivity, hostile sexists may not differentiate in their targets for sexual aggression.

Using Developmental Theories to Inform the Design of Technology for Children

Electronic Blocks are a new programming environment, designed specifically for children aged between three and eight years. As such, the design of the Electronic Block environment is firmly based on principles of developmentally appropriate practices in early childhood education. The Electronic Blocks are physical, stackable blocks that include sensor blocks, action blocks and logic blocks. Evaluation of the Electronic Blocks with both preschool and primary school children shows that the blocks' ease of use and power of engagement have created a compelling tool for the introduction of meaningful technology education in an early childhood setting. The key to the effectiveness of the Electronic Blocks lies in an adherence to theories of development and learning throughout the Electronic Blocks design process.
