Repetition Errors in Habitual Prospective Memory: Elimination of Age Differences via Complex Actions or Appropriate Resource Allocation

ABSTRACT

A challenge in habitual prospective memory tasks (e.g., taking medication) is remembering whether or not one has already performed the action. Einstein, McDaniel, Smith, and Shaw (1998 Einstein, G. O., McDaniel, M. A., Smith, R. E. and Shaw, P. 1998. Habitual prospective memory and aging: Remembering intentions and forgetting actions. Psychological Science, 9: 284–288. [Crossref], [Web of Science ®] , [Google Scholar], Psychological Science, 9, 284) showed that older adults were more likely to incorrectly repeat an action on habitual prospective memory tasks. Extending this research, we (a) biased participants either toward repetition or omission errors, (b) investigated whether performing a more complicated motor action can reduce repetition errors for older adults, and (c) examined participants' resource allocation to the prospective memory task. Older adults committed more repetition errors than younger adults regardless of biasing instructions when ongoing task demands were challenging (Experiment 1). Performing the more complex motor action, however, reduced repetition errors for older adults. Further, when the ongoing task was less demanding, older adults' repetition errors declined to levels of younger adults (Experiment 2). Consistent with this finding, the resource allocation profiles suggested that older participants were monitoring their output (prospective memory execution) in each trial block.     

Training attentional control in older adults

ABSTRACT

Recent research has demonstrated benefits for older adults from training attentional control using a variable priority strategy, but the construct validity of the training task and the degree to which benefits of training transfer to other contexts are unclear. The goal of this study was to characterize baseline performance on the training task in a sample of 105 healthy older adults and to test for transfer of training in a subset (n?=?21). Training gains after 5 days and extent of transfer was compared to another subset (n?=?20) that served as a control group. Baseline performance on the training task was characterized by a two-factor model of working memory and processing speed. Processing speed correlated with the training task. Training gains in speed and accuracy were reliable and robust (ps <.001, η²?=?.57 to .90). Transfer to an analogous task was observed (ps <.05, η²?=?.10 to .17). The beneficial effect of training did not translate to improved performance on related measures of processing speed. This study highlights the robust effect of training and transfer to a similar context using a variable priority training task. Although processing speed is an important aspect of the training task, training benefit is either related to an untested aspect of the training task or transfer of training is limited to the training context.     

Management of Post-Traumatic Stress Disorder in the Military: An Intervention Model

Military Forces are involved in combat, peacekeeping operations and disaster management. The nature of such operations include violent conflict, death of women and children, child soldiers and own forces. These traumatic circumstances can contribute to the development of post traumatic stress disorder (PTSD) in members involved. This article discusses the role and function of psychological debriefing for trauma with operational military units. It also proposes a preliminary intervention model to manage PTSD in military forces.     

Towards happiness interventions: construct clarification and intervention methodologies

The aim of this study was to investigate the main streams of research on happiness, the approaches/models flowing from these philosophies and the methodology of happiness interventions. A systematic review was performed outlining the authors, the purpose of the research, the nature of the sample/setting, the method utilised and the key findings. Peer-reviewed articles published between 1950 and 2013, written in English/Afrikaans, and which examined the concepts of happiness were analysed. The results showed three causes for failing interventions: (a) unidimensional models/ approaches towards happiness, (b) targeting the concept of happiness instead of mediating factors; and (c) fragmented methodological interventions. The results support the need for a multidimensional model of happiness. Interventions focusing on psychological processes and utilising multi-facet methodologies should be developed and implemented to promote happiness. This study contributes to the existing literature by providing an integrative framework for positive psychological interventions directed at happiness.     

Orientation,containment and the emergence of symbolic thinking

Orientation is viewed in this paper as an important dimension of containment for the development of thinking. Orientation refers to the particular positioning in space and time of mother and infant so they can find one another and then containment can take place. Bion's container–contained model for the development of thinking is based on the capacity of the mother's mind to function as a ‘home’ for the infant's primitive projections. Containment and orientation are explored in relation to an ancient Greek object called ‘σ?μβολον’ [symbolon], which I use here as a metaphor for the early negotiation between mother and infant to achieve a correct matching to each other's orientation. This is then mobilized and re‐enacted between analyst and patient in the psychoanalytic process. Orientation as part of the container–contained model enables us to view the development of thinking from a new perspective with greater integration of cognitive and emotional aspects. The clinical implication of the concept of orientation is explored in relation to the process of engagement/disengagement between analyst and patient and is illustrated by clinical material.     

Effects of Potential Partners' Costume and Physical Attractiveness on Sexuality and Partner Selection

Male and female college students in the United States (N = 224) viewed models who had been prerated for physical attractiveness and who were dressed in costumes representing one of three levels of socioeconomic status (SES). Subjects reported their willingness to engage with these stimulus persons in six relationships involving various levels of marital potential and sexual involvement. Models' costume status had greater effects on female subjects' willingness than on male subjects' willingness to enter all six relationships. This difference was larger when the physical attractiveness of models was low than when it was high. Costume status also affected female subjects' ratings of male models' attractiveness but did not affect male subjects' ratings of female models' attractiveness. Results supported eight hypotheses derived from evolutionary theory: In choosing partners, men and women weighed potential partners' SES and physical attractiveness differently, and these factors may have different behavioral implications depending on the degree to which sexual relations, or marital potential, or both, are involved.     

Reciprocal Markov Modeling of Feedback Mechanisms Between Emotion and Dietary Choice Using Experience-Sampling Data

With intensively collected longitudinal data, recent advances in the experience-sampling method (ESM) benefit social science empirical research, but also pose important methodological challenges. As traditional statistical models are not generally well equipped to analyze a system of variables that contain feedback loops, this paper proposes the utility of an extended hidden Markov model to model reciprocal the relationship between momentary emotion and eating behavior. This paper revisited an ESM data set (Lu, Huet, &; Dube, 2011 Lu, J., Huet, C., &; Dubé, L. (2011). Emotional reinforcement as a protective factor for healthy eating in home settings. The American Journal of Clinical Nutrition, 94(1), 254–261. http://dx.doi.org/10.3945/ajcn.110.006361[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) that observed 160 participants' food consumption and momentary emotions 6 times per day in 10 days. Focusing on the analyses on feedback loop between mood and meal-healthiness decision, the proposed reciprocal Markov model (RMM) can accommodate both hidden (“general” emotional states: positive vs. negative state) and observed states (meal: healthier, same or less healthy than usual) without presuming independence between observations and smooth trajectories of mood or behavior changes. The results of RMM analyses illustrated the reciprocal chains of meal consumption and mood as well as the effect of contextual factors that moderate the interrelationship between eating and emotion. A simulation experiment that generated data consistent with the empirical study further demonstrated that the procedure is promising in terms of recovering the parameters.     

A Gradual Effects Model for Single-Case Designs

Single-case designs are a class of repeated measures experiments used to evaluate the effects of interventions for small or specialized populations, such as individuals with low-incidence disabilities. There has been growing interest in systematic reviews and syntheses of evidence from single-case designs, but there remains a need to further develop appropriate statistical models and effect sizes for data from the designs. We propose a novel model for single-case data that exhibit nonlinear time trends created by an intervention that produces gradual effects, which build up and dissipate over time. The model expresses a structural relationship between a pattern of treatment assignment and an outcome variable, making it appropriate for both treatment reversal and multiple baseline designs. It is formulated as a generalized linear model so that it can be applied to outcomes measured as frequency counts or proportions, both of which are commonly used in single-case research, while providing readily interpretable effect size estimates such as log response ratios or log odds ratios. We demonstrate the gradual effects model by applying it to data from a single-case study and examine the performance of proposed estimation methods in a Monte Carlo simulation of frequency count data.     

Negative Treatment Effects in Dyadic Psychotherapy: A Focus on Prevention and Intervention Strategies

Therapy holds the potential to harm as well as help. This paper highlights approaches that may help prevent or decrease the incidence of negative effects in psychotherapy. These approaches include supervision, peer consultation, ongoing assessment of the therapeutic process, therapist-client matching, and referrals and transfers. We hope that this paper will serve as a stimulus for clinicians, psychotherapy researchers, and educators to put forth collabo-rative effort into identifying variables directly associated with adverse treat- ment outcomes and determining appropriate prevention and intervention strategies.     

Improving academic performance and mental health through a stress management intervention: outcomes and mediators of change

Two hundred and nine pupils were randomly allocated to either a cognitive behaviourally based stress management intervention (SMI) group, or a non-intervention control group. Mood and motivation measures were administered pre and post intervention. Standardized examinations were taken 8-10 weeks later. As hypothesized, results indicated that an increase in the functionality of pupils' cognitions served as the mechanism by which mental health improved in the SMI group. In contrast, the control group demonstrated no such improvements. Also, as predicted, an increase in motivation accounted for the SMI group's significantly better performance on the standardized, academic assessments that comprise the United Kingdom's General Certificate of Secondary Education. Indeed, the magnitude of this enhanced performance was, on average, one-letter grade. Discussion focuses on the theoretical and practical implications of these findings.
