Some suggestions for the conduct of biographical research

Despite the strong and growing interest in biography, few psychologists engage in such studies themselves or feel competent to supervise them. Yet biography is a naturalistic form of empirical research and a rich source of ideas about the development of the individual across the life span. I offer a set of five suggestions for the conduct of biographical research and illustrate its use with examples drawn from archival and biographical interviewing studies. Three of the five suggestions concern the selection, presentation, and interpretation of data, areas where the psychologist's concern about investigator bias and reliability of interpretation has been greatest.     

Effects of pentobarbital sodium anesthesia and neurohumoral agents on the cardiac orienting reflex

Studies of the cardiac orienting reflex in 16 dogs, moderately anesthetized and awake are reported. In the anesthetized dogs prominent transient heart rate decrease was commonly noted within one or two beats after the onset of various auditory stimuli, and less often after visual stimuli. This cardiac inhibition was neither as prominent nor as frequent in occurrence in awake dogs. The respiratory cycle at stimulus onset influenced the appearance and degree of heart rate decrease, with the greatest and most frequent decreases occurring during the expiratory phase. Atropine abolished the response. There was little evidence of habituation of this orienting response under anesthesia, although “waxing” and “waning” apparently related to minute-by-minute fluctuations in degree of unconsciousness, occurred. These findings are discussed in relation to neurophysiological and neuroanatomical correlates of orienting responses, hypotheses of orienting and attention and cardiovascular neurohumoral mediators.     

Coronary blood flow in dogs: Effect of person

Experiments on dogs with electromagnetic flow probes implanted around a coronary artery and the ascending aorta indicate that the entry of a person into the experimental chamber can cause a remarkable increase in coronary blood flow. Heart rate usually increases considerably, blood pressure increases only slightly, while aortic blood flow increases at variable times before and after coronary blood flow. It is not yet clear whether these cardiovascular effects are due purely to “effect of person” or to conditioning, with the person as the signal for the momentary coronary occlusion (which the person subsequently accomplishes by manually closing a snare).     

Resolving the theory of planned behaviour's 'expectancy-value muddle' using dimensional salience

The theory of planned behaviour is one of the most widely used models of decision-making in the health literature. Unfortunately, the primary method for assessing the theory's belief-based expectancy-value models results in statistically uninterpretable findings, giving rise to what has become known as the 'expectancy-value muddle'. Moreover, existing methods for resolving this muddle are associated with various conceptual or practical limitations. This study addresses these issues by identifying and evaluating a parsimonious method for resolving the expectancy-value muddle. Three hundred and nine Australian residents aged 18-24 years rated the expectancy and value of 18 beliefs about posthumous organ donation. Participants also nominated their five most salient beliefs using a dimensional salience approach. Salient beliefs were perceived as being more likely to eventuate than non-salient beliefs, indicating that salient beliefs could be used to signify the expectancy component. The expectancy-value term was therefore represented by summing the value ratings of salient beliefs, an approach that predicted attitude (adjusted R2?=?0.21) and intention (adjusted R2?=?0.21). These findings suggest that the dimensional salience approach is a useful method for overcoming the expectancy-value muddle in applied research settings.     

Memory for child sexual abuse information: Simulated memory error and individual differences

Building on the simulated-amnesia work of Christianson and Bylin (Applied Cognitive Psychology, 13, 495–511, 1999), the present research introduces a new paradigm for the scientific study of memory of childhood sexual abuse information. In Session 1, participants mentally took the part of an abuse victim as they read an account of the sexual assault of a 7-year-old. After reading the narrative, participants were randomly assigned to one of four experimental conditions: They (1) rehearsed the story truthfully (truth group), (2) left out the abuse details of the story (omission group), (3) lied about the abuse details to indicate that no abuse had occurred (commission group), or (4) did not recall the story during Session 1 (no-rehearsal group). One week later, participants returned for Session 2 and were asked to truthfully recall the narrative. The results indicated that, relative to truthful recall, untruthful recall or no rehearsal at Session 1 adversely affected memory performance at Session 2. However, untruthful recall resulted in better memory than did no rehearsal. Moreover, gender, PTSD symptoms, depression, adult attachment, and sexual abuse history significantly predicted memory for the childhood sexual abuse scenario. Implications for theory and application are discussed.     

Notes on the theory of variable binding term operators

The general theory of variable binding term operators is an interesting recent development in logic. It opens up a rich class of semantic and model-theoretic problems. In this paper we survey the recent literature on the topic, and offer some remarks on its significances and on its connections with other branches of mathematical logic.     

THE MIDDLE AGES: CHANGE IN WOMEN'S PERSONALITIES AND SOCIAL ROLES

It has been argued that the predominant focus of midlife personality development is generativity; other research has found that social roles influence both its onset and its expression. In this article, we examine women's midlife personality development and its relationship to career and family commitments. Results for a sample of 90 women indicated that commitment to particular social projects in early midlife was associated with different patterns of identity, intimacy, and generativity levels at age 62. In addition, women who added social projects to existing projects during adulthood expressed similar levels of identity, intimacy, and generativity at age 62 as women whose social project commitments had stayed the same. For smaller subsamples of women in the study, longitudinal analyses assessed changes in personality development within middle age as well as the relationship between personality and the maintenance or addition of social projects. These results highlight important variation among women who followed different adult life paths.     

A review of Evidence‐Based Evaluation of Measures for Assessing Social and Emotional Well‐Being in Indigenous Australians

Addressing low levels of social and emotional well‐being (SEWB) in Indigenous communities has been a national strategic priority for over 10 years and yet progress in assessing the impact of interventions has been slow. One of the key factors limiting the development of evidence‐based practice has been the lack of well‐validated instruments to assess SEWB and how it changes over time as a result of intervention. This article systematically reviews available measures, classifying them in terms of the evidence base that exists to support their use. It is concluded that there is an ongoing need to develop psychometrically sound, comprehensive, culturally appropriate measures to operationalise Indigenous SEWB at a population health, programme evaluation, and clinical level. It is suggested that seven pathways be followed to achieve this goal, including the need to recognise that the gold standard status for Indigenous measurement tools cannot be ascribed based on evidence‐based assessment criteria alone.
