Plasticity of brain and cognition in older adults

Aging is typically related to changes in brain and cognition, but the aging process is heterogeneous and differs between individuals. Recent research has started investigating the influence of cognitive and physical training on cognitive performance, functional brain activity, and brain structure in old age. The functional relevance of neural changes and the interactions among these changes following interventions is still a matter of debate. Here we selectively review research on structural and functional brain correlates of training-induced performance changes in healthy older adults and present exemplary longitudinal intervention studies sorted by the type of training applied (i.e., strategy-based training, process-specific training, and physical exercise). Although many training studies have been conducted recently, within each task domain, the number of studies that used comparable methods and techniques to assess behavioral and neural changes is limited. We suggest that future studies should include a multimodal approach to enhance the understanding of the relation between different levels of brain changes in aging and those changes that result from training. Investigating inter-individual differences in intervention-induced behavioral and neuronal changes would provide more information about who would benefit from a specific intervention and why. In addition, a more systematic examination of the time course of training-related structural and functional changes would improve the current level of knowledge about how learning is implemented in the brain and facilitate our understanding of contradictory results.     

The theory of planned behaviour and breast self-examination: assessing the impact of past behaviour, context stability and habit strength

This study applied the theory of planned behaviour (TPB) to the prediction of breast self-examination (BSE) intentions and behaviour, and tested whether the frequency of past behaviour and context stability moderates intention-behaviour and habit-behaviour relations. Seventy-seven females completed measures of the TPB, frequency of past behaviour, context stability and habit strength (Self-Report Habit Index). BSE behaviour was assessed at 1-month follow-up (n?=?66). The TPB explained 33% of the variance in BSE intentions and 11% of the variance in time 2 BSE. The frequency of past behaviour moderated the intention-behaviour relationship such that the intention was only positively related to time 2 BSE behaviour when the frequency of past behaviour was low. Context stability and the combination of the frequency of past behaviour?×?context stability moderated the habit-behaviour relationship such that habit strength was only positively related to time 2 BSE behaviour when context stability and the combination of frequency of past behaviour?×?context stability were high. The results are consistent with the proposal that behaviours that are performed frequently in stable contexts are predominantly under the control of habitual processes, whereas behaviours that are performed infrequently in unstable contexts are predominantly under the control of intentional processes.     

Memory plasticity across the life span: uncovering children's latent potential

Memory plasticity, or the ability to improve one's memory performance through instruction and training, is known to decline during adulthood. However, direct comparisons among middle childhood, adulthood, and old age are lacking. The authors examined memory plasticity in an age-comparative multisession training study. One hundred and eight participants ages 9-10, 11-12, 20-25, and 65-78 years learned and practiced an imagery-based mnemonic technique to encode and retrieve words by location cues. Individuals of all ages were able to acquire and optimize use of the technique. Older adults and children showed similar baseline performance and improvement through mnemonic instruction. However, in line with tenets from life-span psychology (P. B. Baltes, 1987), children profited more from mnemonic practice and reached higher levels of final performance than did older adults.     

Discussions on the large group

At the heart of this article are dialogues with three distinguished large group leaders: Patrick de Mare, Earl Hopper and Lionel Kreeger. They address, with Yvonne Agazarian, some of the major issues in leading large groups: terror and chaos, projective identification, annihilation anxiety, and the impact of size, structure, and boundary management on the potential for change and transformation in the large group. Also discussed are the twin heritage of both psychodynamic and sociological theory and the influence of psychoanalysis, basic assumption theory, information theory, general systems theory, and field theory on the current understanding of large group as the context for therapeutic change. The authors also introduce a theory of living human systems, which views the large group as one system in a hierarchy of isomorphic systems and identifies the subgroup as the fulcrum for change. From this systems-centered perspective, changing the structure and function of communication within subgroups simultaneously changes both the large group and the individual subgroup members.FAGPA is a consulting affiliate of Friends Hospital and maintains a private practice in Philadelphia.

Modeling the Bullying Prevention Program Preferences of Educators: A Discrete Choice Conjoint Experiment

We used discrete choice conjoint analysis to model the bullying prevention program preferences of educators. Using themes from computerized decision support lab focus groups (n = 45 educators), we composed 20 three-level bullying prevention program design attributes. Each of 1,176 educators completed 25 choice tasks presenting experimentally varied combinations of the study’s attribute levels. Latent class analysis yielded three segments with different preferences. Decision Sensitive educators (31%) preferred that individual schools select bullying prevention programs. In contrast, Support Sensitive educators (51%) preferred that local school boards chose bullying prevention programs. This segment preferred more logistical and social support at every stage of the adoption, training, implementation, and long term maintenance processes. Cost Sensitive educators (16%) showed a stronger preference for programs minimizing costs, training, and implementation time demands. They felt prevention programs were less effective and that the time and space in the curriculum for bullying prevention was less adequate. They were less likely to believe that bullying prevention was their responsibility and more likely to agree that prevention was the responsibility of parents. All segments preferred programs supported by the anecdotal reports of colleagues from other schools rather than those based on scientific evidence. To ensure that the bullying prevention options available reflect the complex combination of attributes influencing real world adoption decisions, program developers need to accommodate the differing views of the Decision, Support, and Cost Sensitive segments while maximizing the support of parents and students.     

The Quest for ‘A Common Word’: Initial Christian Responses to a Muslim Initiative

To a world experiencing heightened suspicion and distrust between Christians and Muslims, a call for dialogue and understanding between the two faiths may seem a welcome event. Such a call was issued in October of 2007 when 138 Muslims from around the world sent an invitation to Christian leaders to cease their mutual fear and diatribe, find some measure of theological common ground, and work together for world peace. What motivated such an initiative, and how has it been received? In this essay we will examine some of the reasons for the call, the content of the invitation, and the kinds of responses given by Christian individuals, denominations and communities.     

Evidence for a visuo-spatial scratch-pad in working memory

Experiments are reported which address the nature of the working memory system. Articulatory suppression (continuous recital of the digits 1 to 4) disrupted concurrent performance of a verbal reasoning task, but had no effect upon performance of a spatial reasoning task. In contrast, spatial suppression (continuous sequential tapping) produced reliable interference only with spatial reasoning. These findings are taken as consistent with Baddeley's argument for two slave systems in working memory: the articulatory loop and the more controversial visuo-spatial scratch-pad.     

Deconstructing 'brainwashing' within cults as an aid to counselling psychologists

With the approach of the new millennium there was increased activity within many of the new cultic movements. Many of these organizations promise a future paradise on earth, and can be identified as millenarian cults. Others predicted the end of the world with the focus for this event being the new millennium, the beginning of which is mutable, some claiming it for the year 2000 others the year 2001. The date for the end of the world can by quite idiosyncratic. It was, for instance, believed by the Movement for the Restoration of the Twelve Commandments to be due in March 2000, when over 1000 members of this particular Ugandan cult lost their lives, many through strangulation. The death toll was a stark demonstration of what appears to be some form of extreme control exercised within such groups. It has been estimated that there are between 500 and 800 different cults active in the United Kingdom with membership ranging from under ten people to thousands. This activity indicates that counselling psychologists need to be aware of the problem of the psychological damage with which some members or ex-members of cults continue to present and of the techniques of control practised within the cult and the effect that these techniques have on members. These types of techniques and the resultant negative psychological consequences are the focus of this paper. This paper aims to begin to educate counselling psychologists in the techniques used within cults which effect social control. It intends to equip counselling psychologists to work with a group of clients, that they will meet on an increasing basis as the new millennium, whatever date is allocated to it, approaches and passes. That is if heaven on earth or the earth's destruction does not materialize.     

Anxiety and Asthma Symptoms in Urban Adolescents with Asthma: The Mediating Role of Illness Perceptions

Twenty to 40% of adolescents with asthma experience significant symptoms of anxiety. This study examined the mediational role of illness perceptions in the relationship between anxiety and asthma symptoms in adolescents. One hundred fifty-one urban adolescents (ages 11–18) with asthma completed measures of illness perceptions, and anxiety and asthma symptoms. Using the Baron and Kenny approach and Sobel tests, we examined whether illness perceptions mediated the anxiety-asthma symptom relationship. Three illness perceptions significantly mediated the relationship between anxiety and asthma symptoms, z = 1.97–2.13, p < .05; adjusted R ² = 0.42–0.51, p < .05. Greater anxiety symptoms were associated with perceptions that asthma negatively impacted one’s life and emotions and was difficult to control. These negative illness perceptions were, in turn, related to greater asthma symptoms. Illness perceptions helped explain the anxiety-asthma symptoms link in adolescents. Results suggest that targeting illness perceptions in adolescents with asthma and anxiety may help reduce asthma symptoms.
