Preschool children's proto-episodic memory assessed by deferred imitation

In two experiments, both employing deferred imitation, we studied the developmental origins of episodic memory in two- to three-year-old children by adopting a “minimalist” view of episodic memory based on its What–When–Where (“WWW”: spatiotemporal plus semantic) content. We argued that the temporal element within spatiotemporal should be the order/simultaneity of the event elements, but that it is not clear whether the spatial content should be egocentric or allocentric. We also argued that episodic recollection should be configural (tending towards all-or-nothing recall of the WWW elements). Our first deferred imitation experiment, using a two-dimensional (2D) display, produced superior-to-chance performance after 2.5 years but no evidence of configural memory. Moreover, performance did not differ from that on a What–What–What control task. Our second deferred imitation study required the children to reproduce actions on an object in a room, thereby affording layout-based spatial cues. In this case, not only was there superior-to-chance performance after 2.5 years but memory was also configural at both ages. We discuss the importance of allocentric spatial cues in episodic recall in early proto-episodic memory and reflect on the possible role of hippocampal development in this process.     

Creativity and Certain Personality Traits: Understanding the Mediating Effect of Intrinsic Motivation

Two brief, 15-minute measures of creative ability have become available quite recently. The Abbreviated Torrance Test for Adults (ATTA) objectively measures creative ability in terms of the creativity of answers over 3 tasks. The Abedi Test of Creativity (ATC) subjectively measures creative ability by means of a self-rating questionnaire. Our first study examined the predictive validity of both methods by correlating prospective marketing employees' ATTA and ATC scores with the expert-judged creativity of a marketing campaign that they were asked to design. The objective ATTA test scores correlated substantially with creative performance, unlike the subjective ATC self-rating method that was much less predictively valid. A second study with current employees of a marketing agency demonstrated discriminant validity for the ATTA by revealing that ATTA scores and supervisor ratings of creative ability correlated highly for longer-term employees, but poorly for new recruits. Based on the results of these 2 studies, we propose an even shorter-scored version of the ATTA for use in business settings.     

The German Reformation and the Mathematization of the Created World

This article explores the emergence of mathematics and mathematical method as a means of defining authoritative truth in the thought of some scholars in the German Reformation. Against the background of Martin Luther's critique of Aristotelian philosophy, Philip Melanchthon presented mathematics as an ideal discipline for preparing the mind to understand God. His approach drew on the work of humanist mathematicians such as Regiomontanus. It finds resonances in the work of the Basel humanist Simon Grynaeus, and (in a less mathematically informed way) in the thought of Peter Ramus. These discussions about the divine nature and certainty of mathematical truth formed the context within which Johannes Kepler's Platonist astronomy emerged.     

Monitoring the Changing Status of Semantic Memory in Alzheimer's Disease: An Evaluation of Several Process Measures

The deficits in generating correct words on verbal fluency tasks exhibited by patients with Alzheimer's disease (AD) are accompanied by fewer switching responses, smaller phonemic and semantic cluster sizes, and greater than normal percentages of errors and category labels. On category fluency tasks, patients generate a greater proportion of words that are prototypical of their semantic class. To determine whether any of these supplementary measures of verbal fluency performance might be useful in revealing processes involved in the decline of semantic memory in AD, we studied 219 patients with AD and 115 elderly control participants longitudinally. Previously reported group differences between patients and controls were replicated, but changes in average cluster size, error rates, and prototypicality were not related to changes in overall severity of dementia and test-retest stability was only modest. The change in the percentage of labels generated on the Supermarket task was related to changes in dementia severity, but test-retest stability on this measure was quite low. All of these process measures appear to reflect only the current status of the patient's attention to the task and access to semantic knowledge, but they do not forecast future performance. The numbers of switching responses on the fluency tasks were sensitive to differences between clinically deteriorated and clinically stable patients and showed fairly high test-retest stability. However, the number of switching responses is so highly correlated with the number of correct words that it contributes little to the understanding of the processes involved in the progressive decline in performance on fluency tasks by patients with AD.     

Increased Proportion of Farm Animal Names Generated by Patients with Alzheimer's Disease: What Does it Mean?

Binetti et al. (1995) reported that patients with Alzheimer's disease (AD) produced fewer semantic clusters than controls on the Animals Fluency task; of the clusters produced, 80% involved farm animals for the patients with AD compared to 40% for controls. In the present study we replicated the finding of Binetti et al.; however, the differential distribution of animal names by subcategory for the patients and controls could be accounted for by differences in the overall output and by assuming that word generation was strictly determined by prototypicality of the animal names. Thus, the increased proportion of farm animal names produced by patients with AD can be accounted for simply by postulating impaired access to semantic memory rather than degraded representations, the idea favored by Binetti et al.     

Intergenerational practice in the community: A focused ethnographic evaluation

An intergenerational community intervention based on contact theory and using ‘photovoice’ methods was designed to change negative age‐group stereotypes and promote sense of community. A focused ethnographic approach was adopted. Participants were 18 young people and 13 older adults. Data from focus groups, carried out with each generation separately, and observational field notes were analysed using thematic analysis; credibility checks were carried out by auditing and respondent validation. Before the intergenerational intervention, both generations presented age‐group stereotypes and both experienced only a weak sense of community. After the intervention, both generations felt that intergenerational contact had reduced age‐group stereotypes and enhanced recognition of intergenerational similarity; many also articulated a positive sense of community. The intervention has promise for helping young people and older adults to feel more socially included. Copyright © 2011 John Wiley & Sons, Ltd.     

Part set cuing in older adults: further evidence of intact forgetting in aging

The aim of this study was to look at the effect of aging on part set cuing while equating for baseline performance in episodic memory. Younger and older participants listened to three different word lists, each containing 24 words relating to a particular category. During recall, 0, 33, or 66% of the items presented in the learning phase were re-presented as cues. The results showed that recall of the never cued items was equally impaired by the presence of cues in younger and older adults, thus showing equivalent part set cuing effects in both groups. These results parallel previous findings showing equivalent inhibitory effects in younger and older adults with tasks that do not require executive control and provide additional support to previous studies challenging the view that frontal/executive processes play a major role in part set cuing.     

The Relation Between Maternal ADHD Symptoms &; Improvement in Child Behavior Following Brief Behavioral Parent Training is Mediated by Change in Negative Parenting

This study examined the extent to which maternal attention-deficit/hyperactivity disorder (ADHD) symptoms predict improvement in child behavior following brief behavioral parent training. Change in parenting was examined as a potential mediator of the negative relationship between maternal ADHD symptoms and improvement in child behavior. Seventy mothers of 6–10 year old children with ADHD underwent a comprehensive assessment of adult ADHD prior to participating in an abbreviated parent training program. Before and after treatment, parenting was assessed via maternal reports and observations and child disruptive behavior was measured via maternal report. Controlling for pre-treatment levels, maternal ADHD symptomatology predicted post-treatment child disruptive behavior problems. The relation between maternal ADHD symptomatology and improvement in child behavior was mediated by change in observed maternal negative parenting. This study replicated findings linking maternal ADHD symptoms with attenuated child improvement following parent training, and is the first to demonstrate that negative parenting at least partially explains this relationship. Innovative approaches combining evidence-based treatment for adult ADHD with parent training may therefore be necessary for families in which both the mother and child have ADHD. Larger-scale studies using a full evidence-based parent training program are needed to replicate these findings.     

Leaving Room for Complexity in Attempts to Understand Associations between Romantic Relationships and Health: Commentary on Wanic and Kulik

Wanic and Kulik (2011) discuss research addressing links between romantic relationships and health, with a focus on gender differences in response to relationship conflict among couples residing in the U.S. Their subordination-reactivity hypothesis proposes that women??s subordinate role in relationships renders them more vulnerable to relationship conflict and less likely to reap the health benefits of relationships than men. They contrast their hypothesis with the interpersonal orientation hypothesis and provide convincing evidence for further examination of the importance of status in relationships. We add to their commentary by noting the potential importance of considering research examining men??s vulnerability when faced with relationship dissolution, personality traits (e.g., dominance) in addition to social roles within relationships, and by describing preliminary research addressing gay and lesbian partnerships. We conclude by imploring researchers to remain tolerant of ambiguity in this area of research as new findings continue to reveal the significant but complex associations between romantic relationship experiences and health for both men and women.     

Do 18-month-olds really attribute mental states to others? A critical test

In the research reported here, we investigated whether 18-month-olds would use their own past experience of visual access to attribute perception and consequent beliefs to other people. Infants in this study wore either opaque blindfolds (opaque condition) or trick blindfolds that looked opaque but were actually transparent (trick condition). Then both groups of infants observed an actor wearing one of the same blindfolds that they themselves had experienced, while a puppet removed an object from its location. Anticipatory eye movements revealed that infants who had experienced opaque blindfolds expected the actor to behave in accordance with a false belief about the object's location, but that infants who had experienced trick blindfolds did not exhibit that expectation. Our results suggest that 18-month-olds used self-experience with the blindfolds to assess the actor's visual access and to update her belief state accordingly. These data constitute compelling evidence that 18-month-olds infer perceptual access and appreciate its causal role in altering the epistemic states of other people.
