Organisational Consultancy, Institutional Dynamics and the Role of the Student Counsellor

The despair and uncertainty apparent in some parts of the current educational environment is likely to give rise to an increase in the occurrence of unhealthy institutional defence mechanisms. The implications of such developments for the counsellor are explored. In particular, it is argued that the latter may have to assume the role of organisational consultant and become more politically engaged within the institution, if the integrity and dignity of counselling are to survive.     

An analysis of latency and interresponse time in free recall

In four experiments, subjects freely recalled previously studied items while a voice key and computer recorded each item’s recall latency relative to the onset of the recall period. The measures of recall probability and mean recall latency were shown to be empirically independent, demonstrating that there exists no a priori relationship between the two. In all four experiments, latency distributions were fit well by the ex-Gaussian, suggesting that retrieval includes a brief normally distributed initiation stage followed by a longer exponentially distributed search stage. Further, the variation in mean latency stemmed from the variation in the duration of the search stage, not the initiation stage. Interresponse times (IRTs), the time elapsed between two successive item recalls, were analyzed as well. The growth of mean IRTs, plotted as a function of output position, was shown to be a simple function of the number of items not yet recalled. Finally, the mathematical nature of both free recall latency and IRT growth are shown to be consistent with a simple theoretical account of retrieval that depicts mean recall latency as a measure of the breadth of search.     

The psychologist's role in assessing and facilitating patients' knowledge of advance directives in medical settings: A preliminary investigation

In a time of budgetary shortfalls in the medical industry, an aging population, and an increased emphasis on health care choices, psychologists are being called upon to administer advance medical directive programs to patients. This study reports preliminary findings from a program to assess and facilitate patients' knowledge of advance directives (ADs) by the Psychology Service at the Ann Arbor VA Medical Center. The participant pool included 243 male veteran patients admitted to medical and surgical wards at the hospital. The intervention included the use of a computer-generated prompt for consultation, which was sent to the psychology staff in response to a patient inquiry regarding ADs. It also involved an increased emphasis on the delivery of written material on ADs by the admissions clerks. The intervention appeared to result in a modest increase in patients' knowledge of advance directives. Suggestions are offered for areas that should be emphasized in future attempts to increase patients' knowledge and utilization of advance directives.     

Trauma histories and attachment styles of members of the International Society for Traumatic Stress Studies

The study is focused on the training, demographics, perceived emotional and physical health, past traumatic experience histories, and attachment styles of mental health professionals in the field of trauma (members of the International Society for Traumatic Stress Studies). While the data set is limited by a low response rate of 20%, the uniqueness of the sample and distinctive themes yield insight into the experience of trauma and its association with attachment style.     

Endogenous shifts of covert attention operate within multiple coordinate frames: evidence from a feature-priming task

The locations of visual objects and events in the world are represented in a number of different coordinate frameworks. For example, a visual transient is known to attract (exogenous) attention and facilitate performance within an egocentric framework. However, when attention is allocated voluntarily to a particular visual feature (ie endogenous attention), the location of that feature appears to be variously encoded either within an allocentric framework or in a spatially invariant manner. In three experiments we investigated the importance of location for the allocation of endogenous attention and whether egocentric and/or allocentric spatial frameworks are involved. Primes and targets were presented in four conditions designed to vary systematically their spatial relationships in egocentric and allocentric coordinates. A reliable effect of egocentric priming was found in all three experiments, which suggests that endogenous shifts of attention towards targets defined by a particular feature operate in an egocentric representation of visual space. In addition, allocentric priming was also found for targets primed by their colour or shape. This suggests that attending to targets primed by nonspatial attributes results in facilitation that is localised in more than one coordinate frame of spatial reference.     

Perception of coherent motion in random dot displays by pigeons and humans

Pigeons and humans were required to discriminate coherent from random motion in dynamic random dot displays. Coherence and velocity thresholds were determined for both species, and both thresholds were found to be substantially higher for pigeons than for humans. The results are discussed with reference to differences in motion processing in mammals and birds. It is suggested that the inferior motion sensitivity of pigeons can be attributed to poorer spatiotemporal motion integration.     

Spiritual Practice,Health Promotion,and the Elusive Soul: Perspectives from Public Health

Spirituality and religion are topics of increasing interest in U.S. society and popular culture as well for many health professions, including medicine, psychology, and public health. This article comments on Mark Graves’ (2008) synthesis of science and spirituality/religion, Mind, Brain, and the Elusive Soul from the perspective of a public health professional. I briefly review the sources, extent, and conceptual approaches of emerging scientific and health interest in spirituality/religion. Spiritual practices are identified as phenomena of central interest. Major concepts of Graves’ synthesis are reviewed, and the soul’s relevance to spiritual growth, popular culture, and scientific application is discussed. Several questions are posed as a stimulus to further extension and refinement of Graves’ synthesis.     

The benefit of interleaved mathematics practice is not limited to superficially similar kinds of problems

Most mathematics assignments consist of a group of problems requiring the same strategy. For example, a lesson on the quadratic formula is typically followed by a block of problems requiring students to use that formula, which means that students know the appropriate strategy before they read each problem. In an alternative approach, different kinds of problems appear in an interleaved order, which requires students to choose the strategy on the basis of the problem itself. In the classroom-based experiment reported here, grade 7 students (n = 140) received blocked or interleaved practice over a nine-week period, followed two weeks later by an unannounced test. The mean test scores were greater for material learned by interleaved practice rather than by blocked practice (72 % vs. 38 %, d = 1.05). This interleaving effect was observed even though the different kinds of problems were superficially dissimilar from each other, whereas previous interleaved mathematics studies had required students to learn nearly identical kinds of problems. We conclude that interleaving improves mathematics learning not only by improving discrimination between different kinds of problems, but also by strengthening the association between each kind of problem and its corresponding strategy.
