The effects of overlearning and distributed practise on the retention of mathematics knowledge

In two experiments, 216 college students learned to solve one kind of mathematics problem before completing one of various practise schedules. In Experiment 1, students either massed 10 problems in a single session or distributed these 10 problems across two sessions separated by 1 week. The benefit of distributed practise was nil among students who were tested 1 week later but extremely large among students tested 4 weeks later. In Experiment 2, students completed three or nine practise problems in one session. The additional six problems constituted a strategy known as overlearning, but this extra effort had no effect on test scores 1 or 4 weeks later. Thus, long‐term retention was boosted by distributed practise and unaffected by overlearning. Unfortunately, most mathematics textbooks rely on a format that emphasises overlearning and minimises distributed practise. An easily adopted alternative format is advocated.

Initial Primary Teacher Education Students and Spirituality

In recent years there has begun to be a resurgence of interest in educating the whole child in response to an over emphasis on basic skills teaching. In the study reported in this article, initial primary teacher education students at a regional Australian university were asked to explore and discuss their beliefs about the notion of spirituality. A survey was one of the instruments used and the responses obtained were placed into one of five categories or dimensions of spirituality. These included spirituality and self (reflection); religion; nature (environment/universe); relationships; and major life events (birth/marriage/death). Each of these categories are discussed in relation to a similar study conducted in the United Kingdom. Some implications for teacher educators and their initial primary teacher education students are discussed. These implications are able to help both groups work towards a more spiritually sensitive curriculum which seeks to recognise spiritual development as integral and central for providing a holistic education for all children.     

Utah youth suicide study: psychological autopsy

We conducted a psychological autopsy study to further understand youth suicide in Utah. While traditional psychological autopsy studies primarily focus on the administration of psychometric measures to identify any underlying diagnosis of mental illness for the suicide decedent, we focused our interviews to identify which contacts in the decedent's life recognized risk factors for suicidal behavior, symptoms of mental illness, as well as barriers to mental health treatment for the decedent. Parents and friends recognized most symptoms universally, although friends better recognized symptoms of substance abuse than any other contact. The study results suggest that parents and friends are the most appropriate individuals for gatekeeper training and, in conjunction with other innovative screening programs, may be an effective strategy in reducing adolescent suicide.     

When organizational climate is unambiguous, it is also strong

Several recent studies have addressed the topic of climate strength--the degree to which there is agreement among an organization's members regarding the practices and policies as well as the shared values that characterize the organization. To further investigate antecedents of climate strength, the authors used data from the GLOBE Project, totaling 3,783 individuals from 123 organizations. The authors hypothesized that they would find greater climate strength in organizations with climates reflecting mechanistic as opposed to organic organizational forms. Although the authors did in fact find such a trend, they also unexpectedly uncovered significant and strong nonlinear effects, such that climates that are clearly mechanistic or clearly organic have strong climates, with weaker climates emerging for organizations with more ambiguous climates. These findings provide interesting new avenues to pursue in understanding the origins of climate strength.     

Misconceptions about incline speed for nonlinear slopes

In 3 experiments, college students provided qualitative predictions about a marble's speed along nonlinear inclines. When predicting the outcome of a race between identical marbles along differently shaped ramps, most students predicted incorrectly that the shorter path was necessarily quicker (the shorter-quicker belief). When comparing instantaneous speed at 2 points, most students predicted incorrectly that incline speed depended on the slope at that point (the slope-speed belief). A final experiment provides evidence that the slope-speed belief reflects a deeper fallacy regarding the resistance encountered while traversing inclines and lifting objects. This fallacy also predicts the prevalent belief that heavier objects fall faster than lighter objects during incline descent or free fall.     

Stability of Q-sort attachment security from age two to five

The current report demonstrates reliability and stability of Q-sort attachment security in a sample of 46 mothers and their children seen by two observers at age two and again at age four to six years. Security scores were correlated between ages (r=.44), and a high proportion of item-by-item correlations between ages were also significant.     

Patterns of maternal and infant imitation during play

In contrast to recent experimental studies that have sought to establish the infant's ability to imitate, the goal of the current study was to establish the actual performance of imitation by infants and their mothers during episodes of face-to-face play. Three-min play episodes of 20 mothers and their 13- to 16-week-old infants were videotaped. Instances of mouth openings, lip movements, tongue protrusions, smiling, and vocalizations by both partners were coded. Sequential analyses revealed stochastic patterns of imitation by both interactants. Mothers contingently imitated initiations by their infants and were more likely to make like initiations during action in the same category by their infants. Infants did not show onset-to-onset imitation but did show an increased likelihood to initiate actions when their mothers were engaged in a like action. That imitation by the mother is a pervasive characteristic of such interactions is consistent with earlier suggestions of its role in the acquisition of social and emotional skills. The results suggest that infants also display patterns of matching in early social interactions.     

Interpersonal communication in the health professions: A focus on training

The field of Health Psychology has enjoyed a prodigious growth over the past 15 years. The interpersonal dynamic of the practitioner-patient relationship is one of the areas which has been illuminated thereby accentuating its contribution to effective levels of health care. This paper examines the concepts of interpersonal communication and communication skill. The contribution of skilful communication by health workers to the success with which they discharge their professional duties is considered and present standards of practice critically assessed. Specific areas of inadequacy are identified and possible causative factors postulated. Amongst such factors would appear to be a relative neglect of the interpersonal dimension of the work of the health practitioner during training. A case is made for increased attention being devoted to promoting this facet of professional competence. The major thrust of the paper develops this theme by elaborating a systematic and structured framework for instruction, Communication Skills Training, as an approach to promoting interpersonal efficiency in the health care context.
