A characterization of individual differences in prospective memory monitoring using the Complex Ongoing Serial Task

Prospective memory--remembering to retrieve and execute future goals--is essential to daily life. Prospective remembering is often achieved through effortful monitoring; however, potential individual differences in monitoring patterns have not been characterized. We propose 3 candidate models to characterize the individual differences present in prospective memory monitoring: attentional focus, secondary memory retrieval, and information thresholding. Two experiments using a novel paradigm, the Complex Ongoing Serial Task (COST), investigated the resource allocation patterns underlying individual differences in monitoring. Individuals exhibited differential resource allocation patterns, and the differences remained relatively stable across experimental sessions. Resource allocation patterns associated with information thresholding (high prospective memory, preserved ongoing task performance) and attentional focus (high prospective memory, inefficient ongoing task performance) were superior to secondary memory retrieval (low prospective memory, very inefficient ongoing task performance). Importantly, personality (openness, prevention focus) and cognitive (primary, working, and secondary memory) individual differences influenced monitoring patterns. This research represents the first explicit attempt to elucidate individual differences in prospective memory monitoring patterns.     

Analysing the perceptions of pedestrians and drivers to shared space

Shared space is an approach to improving streets and places where both pedestrians and vehicles are present, with layouts related more to the pedestrian scale and with features encouraging drivers to assume priority having been reduced or removed. It creates a more pedestrian-friendly environment than conventional street layouts, which are based on greater segregation between pedestrians and vehicles, while at the same time introducing uncertainty, which makes drivers engage more fully with their surroundings, leading to lower vehicle speeds and improved safety. This paper investigates the importance of certain person-, context- and design-specific factors affecting the perceptions of pedestrians and drivers to shared space. Using two web-based stated-preference surveys, two sets of responses are collected from pedestrians and drivers, who are presented with different combinations of binary factors forming scenarios. Regression analysis is carried out with logit models for each survey. The results suggest that pedestrians feel most comfortable in shared space under conditions which ensure their presence is clear to other road users – these conditions include low vehicular traffic, high pedestrian traffic, good lighting and pedestrian-only facilities. Conversely, the presence of many pedestrians and, in particular, children and elderly, makes drivers feel uneasy and, therefore, enhances their alertness.     

Rural breast cancer patients,coping and depressive symptoms: A prospective comparison study

Many studies have revealed that individual differences in coping responses to the diagnosis and treatment of breast cancer are associated with psychological adjustment. The vast majority of these studies, however, focus exclusively on urban breast cancer survivors despite that rural breast cancer survivors are likely to have distinct experiences both in general and in relation to breast cancer. The current study quantitatively examined the coping strategies employed by both rural and urban breast cancer patients while they were undergoing radiation therapy. Further, the influence of these coping behaviours on concurrent as well as subsequent depressive symptoms (3 and 6 months later) was examined. The results revealed that the rurality of breast cancer patients was unrelated to the ways in which they coped, but did influence the relationships between some coping responses and depressive symptoms. Specifically, active coping and positive reinterpretation were negatively related to depressive symptoms for more rural breast cancer patients, but not their relatively urban counterparts. Similarly, behavioural disengagement was more strongly related to depressive symptoms for more rural patients. Possible reasons for this pattern of results and implications are discussed.     

The effects of questionnaire length and lottery ticket inducement on the response rate in mail surveys

Abstract

As part of a study on functional gastrointestinal disorders in the Australian community, we surveyed 500 subjects to test the effects of questionnaire length and lottery inducement on the response rate in mail surveys. By random allocation, n = 124 subjects received a short form questionnaire (28 pages) with a lottery ticket, n = 126 received a short form with no lottery ticket, n= 124 received a long form (32 pages) with a lottery ticket and n= 126 received a long form with no lottery ticket. The overall response rate for the study was 74%. The response rates for the short (76.8%) versus long (71.2%) form and lottery ticket (74.2%) versus no lottery ticket (73.8%) were not significantly different. Significantly more short forms compared with longer forms were received after each stage of the follow-up protocol. A long questionnaire can however be successfully used in survey research.     

Psychological treatment and reconstruction with a chronic pain patient

This article describes the psychological treatment of a chronic pain patient using a single case design methodology in order to evaluate changes in symptomatic measures as well as in Repertory Grid Test scores. These changes included a substantial reduction in levels of subjective pain and anxiety as well as a reduction in symptom superordinacy, level of self-dissatisfaction, and positive meaning (“payoff”) of anxiety. Results are discussed in relation to the literature on pain and on personal construct theory.     

Motivational pursuits in the context of human sexual relationships

The current article examines how close relationships combine with individual differences in sex motives (Cooper, Shapiro, & Powers, 1998) to shape sexual experience. We first provide an overview of the motivational approach as it relates to sexual behavior and then describe 2 broad mechanisms (1 transactional, the other interactional) by which motives and relational context combine to shape behavior. Drawing on our past research, we review evidence showing that people select relationship contexts based partly on their motives and that these contexts in turn shape future motives and behavior; that partner motives shape sexual experience above and beyond one's own motives; and that both the broader relationship context and partner motives moderate the effects of one's own motives on sexual experience. We conclude that the nature of motivational pursuits cannot be adequately understood in the abstract, but rather we must take into account the relational context in which one's needs are pursued.     

ACTIONS,HABITS AND CONSTITUTION

In this paper I offer a critique of the view made popular by Davidson that rationalization is a species of causal explanation, and propose instead that in many cases the explanatory relation is constitutive. Given Davidson’s conception of rationalization, which allows that a huge range of states gathered under the heading ‘pro attitude’ could rationalize an action, I argue that whilst the causal thesis may have some merit for some such ‘attitudes’, it has none for others. The problematic ‘attitudes’ are those which can be attributed to the agent only on the basis of her history of doing a certain sort of thing. In other words, they are among the agent’s habits. I argue that such temporally extended states cannot be the causes of any present occurrence. Instead, I suggest we should think of the present action as partly constituting the state in question, and give a corresponding interpretation of the explanatory relation. Such explanations invite us to abandon a conception of agency narrowly based on psychology, in favour of an enriched one which takes an agent’s habits to partly constitute the agent.
