Executive functioning in normal aging: a study of action planning using the Zoo Map Test

A particularly important aspect of executive functioning involves the ability to form and carry out complex plans, that is to say planning. This study aimed to investigate planning in 18 older and 16 younger normal participants using an ecological planning subtask derived from the Behavioural Assessment of the Dysexecutive Syndrome test battery, the "Zoo Map Test." There are two trials. The first trial consists of a "high demand" version of the subtask in which the participants must plan in advance the order in which they will visit designated locations in a zoo (formulation level). In the second, or "low demand" version, the participant is simply required to follow a concrete externally imposed strategy to reach the locations to visit (execution level). The two-way ANOVAs mainly showed more difficulties in elderly adults than in younger adults, more difficulties in formulation level than in execution level, and lastly a greater difference between formulation and execution in older participants than in younger adults. These results suggest that elderly participants have some problems developing logical strategies whereas they are able to execute complex predetermined plans.     

Anticipatory and event related changes in heart rate as indicators of attention processes

The present study was concerned with the question of whether phasic event-related heart rate (HR) changes under easy intake conditions account for the association between anticipatory HR deceleration and task performance in a choice reaction time (RT) task with a fixed foreperiod. The task employed differed from simple RT tasks especially with regard to processing and attention demands. Subjects were required to determine as quickly and accurately as possible whether a probe, presented for 80 ms, was identical or not to one of two distinct memory items, presented at the onset of each trial. Reaction times as well as accuracy of responses were determined. The results of the present study were indicative of a reliable anticipatory HR deceleration which was related to latency of responses to the probe stimulus. Subjects with stronger decelerations reacted faster than subjects with diminished or missing decelerations. Furthermore a relation was found between this association and the heart rate changes to repeated presentations of a non-signal auditory stimulus under habituation conditions. Results were discussed in terms of differences in the regulation or control of attentional processes.     

Social psychology at the crossroads: Its encounter with cognitive and ecological psychology and the interactive perspective

This article discusses the implications for social psychology of recent developments in the neighbouring fields of cognitive and ecological psychology. The authors stress the importance of studying the cognitive processes directly instead of inferring them as hypothetical constructs from aggregate responses. This paradigmatic shift implies a change in the conduct of research from the traditional nomothetic perspective to a neo-idiographic one. A method of representational contextualization is offred to generate the affective and cognitive deep structure from surface, first order data. This structure identified as the internal environment, reflects simultaneously the construction of reality by a situated individual and the recoding rules operating in such a construction.     

Significance of heart rate deceleration in pattern recognition tasks

As strength of foreperiod heart rate (HR) deceleration in reaction time paradigms with a fixed foreperiod has been discussed in terms of activities related to differences in regulations of attentional processes, the present study was concerned with the question of whether this variable also accounts for the variance in the latency of response in two attention-demanding pattern recognition tasks, one of which involved mental rotation. Subjects were required to determine as quickly and as correctly as possible whether a two-dimensional asymmetrical shape was intrinsically identical to a previously presented visual pattern or not, regardless of its rotational position within the picture plane. The first stimulus was always in normal upright position, whereas the probe stimulus could either be rotated or presented in an upright position. The findings of the study are indicative of a reliable relation between anticipatory HR deceleration and reaction time. It was not restricted to detection and response requirements but also held true in the case of additional mental rotation requirements. Strength of anticipatory HR deceleration is therefore interpreted as an indicator of regulations of attentional processes mustered in order to facilitate or to support stimulus detection and response elicitation as well as to prime or to set up the mental structures required in mental rotation. Additional support for this assumption could be found in the analyses of HR changes at the beginning of the response interval.     

Degrading situations,affiliation and social dependency

Research is reported which shows that degrading situations (e.g. a failure on a test) increase affiliative propensity. Four studies demonstrated that this affiliative tendency of degraded subjects is independent of the potential partner's performance and independent of his/her characteristics. The partners appeared to be equally attractive whether or not they witnessed subject's failure, and whether they were individuals or a group. On the other hand, the affiliative desires of praised subjects seem to be oriented rather towards those who benefit from a similar situation. The motivation underlying affiliative behaviour is discussed with regard to social psychological literature. It is suggested that degraded subjects' affiliative behaviour arises from a search for support and that a socially degrading situation places the subject in a state of emotional dependency which is expressed by a non-directional affiliative tendency and vulnerability to social influence. ©1997 John Wiley & Sons, Ltd.     

When patients contribute to the choice of treatment.…

To explore an alternative solution more appropriate to clinical standards than random assignment, 42 mothers consulting for a functional (sleep, feeding) or behavior problem of their infant were given the choice between two forms of mother–infant psychotherapy (Psychodynamic or Interaction Guidance). Clinicians, blind to mother's choice, followed a systematic indication procedure and provided a therapeutic recommendation. Results revealed a very high agreement between mother's choice and therapists' recommendation. Examination of patient and pretreatment variables showed no major differences between the two groups resulting from a choice of treatment procedure. This procedure proved to ensure internal validity of the data and was also able to guarantee external validity. Discussion focuses on the methodological and clinical implications of the findings that support the consideration of the patient as an active participant to his/her treatment. © 1998 Michigan Association for Infant Mental Health     

The Contemporary Relevance of Schillebeeckx's Political Theology: On Ecclesial Participation in the Saving Work of Christ

In this article I explore the relation between God's absolute governance of the world and ecclesial dominion over other communities in a shared political forum that seeks the greatest good of all. On this question I compare the positions of Colin Gunton, Robert Jenson, and Edward Schillebeeckx as representatives of three distinct political theologies. Whereas Gunton's reservation regarding the participation of the church's politics in divine governance shows excessive deference to human sinfulness, Jenson on the contrary tends to absorb God's Rule into ecclesial politics. Drawing upon Schillebeeckx's Christology, I argue that God's absolute Rule is compatible with ecclesial sovereignty; however, this does not allow for unilateral ecclesial dominion over others, inasmuch as God's Rule is disclosed as forgiveness.

Survey return rates as a function of priority versus first-class mailing

Prior research indicates survey procedures that signal significance and individualized mailings have higher response rates. Thus, it was hypothesized that surveys delivered via Priority mail would result in higher return rates than surveys delivered via First-Class. 260 surveys were sent to individuals randomly selected from lists of licensed physical and behavioral healthcare providers in Alaska and New Mexico. Half of the selected individuals were assigned randomly to receive mailings using Priority mail, the other half received First-Class mailings. Return rate was 39% for First-Class and 35% for Priority. Z tests of proportion indicated no statistically significant differences between methods. Given increased costs with no resultant increase in response rate, sending surveys to potential participants via Priority mail does not appear warranted.     

Civic Education and the Good

It is argued that children need to learn about civic issues intheir education because certain virtues are required for a decently organisedsociety. It is also argued that the school has wide obligations to educate theyoung in civics because it is in their best interests. This is not seen asan encroachment on the privacy of the individual. It is explained that theschool has an obligation to impart knowledge to the young.
