Minimized tolerance to the suppressive effects of CCK8 on operant responding

This study was designed to determine if tolerance to cholecystokinin octapeptide (CCK8) could be prevented or minimized by spacing injections, and if an appetitive operant conditioning paradigm provides a sensitive baseline to test the effects of CCK8. Male Sprague-Dawley rats were trained to press a lever for water according to a fixed-interval 60-sec schedule of reinforcement. After response rate stabilized, rats were given a series of CCK8 (0.04 mg/kg, ip) injections spaced several days apart. The first injection of CCK8 produced complete response suppression during the 30-min test session, while later injections produced partial or complete suppression. Thus, tolerance to CCK8, as measured by operant response rate, may be minimized if injections are appropriately spaced.     

The relationship between state anxiety and depressed mood: A validity study

The validity of the A-State Scale of the State-Trait Anxiety Inventory and the Zung Self-Rating Depression Scale was assessed using data from a general health survey. Depression and anxiety states were found to coexist, however, evidence from a factor analysis, showing items from the two tests loaded on separate factors, demonstrated that these states can be measured independently. Both the A-State and the Zung Scales were found to comprise two factors, and for each scale, one factor consisted of positively phrased items, and the other of negative items. The implications of these findings for the construct validity of the two scales are discussed.

Coping strategies and psychological distress in cancer patients before autologous bone marrow transplant

The increased use of bone marrow transplantation (BMT) to treat a variety of cancers has led researchers to study psychological functioning of BMT patients. The majority of studies conducted, however, has focused on adjustment after transplantation. Cancer patients' use of coping strategies before undergoing this procedure may also relate to levels of psychological distress. Our aims were (1) to provide normative coping data, controlling for situation-specific variables with a homogeneous sample, targeted stressor, and fixed time point, using the Ways of Coping Questionnaire; and (2) to identify coping strategies associated with distress before high-dose chemotherapy. Subjects were 49 patients scheduled to receive high-dose chemotherapy and an autologous bone marrow transplant. Consistent with previous coping research, we found that escape-avoidance was related to psychological distress on several measures. Item endorsement analyses of the escape-avoidance subscale suggest that patients may have used more passive than active avoidance strategies. Subsequent participation in a longitudinal study was not affected by initial levels of avoidant coping.     

The Psychology of Religion and the Concept of Revelation

It is argued that the psychology of religion should be seen as interacting with theology in a broader way than is usual at present, especially in relation to the concept of revelation. Examination of revelatory experiences, especially Christ’s resurrection appearances, may be seen in terms of this broader interaction not only as solving certain historical puzzles, but as bringing to fruition Arthur Peacocke's hope for application to spiritual experience of understandings of divine action that have been developed within the science–theology dialogue. The pluralistic implications of this approach are examined, and the possibilities open to psychologists in relation to both interpretation and research strategies are outlined. It is stressed that what is required is not simply interdisciplinarity, as this is usually understood, but transdisciplinarity of the kind that questions the boundaries and methodologies accepted by specialists in one or other of the disciplines concerned.     

A video‐based procedure for the assessment of prospective memory

Prospective memory, or the everyday activity of remembering to remember, is frequently deficient in persons with brain injuries. However, few clinically useful measures of this ability are available. We report the results of three studies using student participants, conducted to examine the psychometric credentials of a video‐based method of assessing prospective remembering. This procedure requires participants to watch a video segment recorded moving through a shopping precinct and to recall preassigned instructions (e.g. ‘Buy a Big Mac at McDonald's’) in response to cues appearing on the videotape. Study 1 showed that the video procedure is reliable and easier to complete when the video footage is set in a familiar location. Study 2 confirmed that familiarity enhances recall and demonstrated that pre‐exposure to the unfamiliar video stimuli could partially attenuate this effect. In Study 3 it was found that performance on the video‐based task was correlated with performance on an equivalent real life memory task providing evidence for criterion validity. The findings from these studies demonstrate that clinical and experimental measures of prospective memory with high ecological validity can be constructed based on video recordings of everyday activities.

Factor Structure of the Burden Interview

Zarit's Burden Interview is the most commonly used measure of burden among family caregivers for demented older adults, but has been criticized for its diverse item content and lack of correspondence to theoretically based multidimensional burden scales. The factor structure of this measure of burden was examined in a sample of 220 family caregivers of demented elderly. The implied 1-factor model and a 2-factor model proposed in the literature were not good fits to the data. Fourteen of the 21 nonglobal items were found to tap three underlying factors of Embarrassment/Anger, Patient's Dependency, and Self-criticism. This factor structure was replicated in a second sample of 108 caregivers. The relationship of these factors to latent factors identified in other multifactorial burden scales suggests a greater degree of convergence across measures than has been assumed.     

Born and raised to be a fraudster

Although a great deal of research has focussed on and continues to focus on fraud prevention and detection, there is still no reliable way to predict who will become a white‐collar criminal/fraudster. Significant benefits would result if and when this can be done. This paper recognizes that there are many common characteristics that exist among fraudsters and investigates whether fraud can be predicted based on the psychological, sociological, and environmental state of children throughout their upbringing. Research shows that children with a negative childhood develop negative habits, emotions, and mentalities, including disorders that can linger well into their adult lives. These negative characteristics can ruin relationships and possibly even influence an individual to commit fraud. This paper provides initial evidence regarding the potential significance of some childhood characteristics that may contribute to the likelihood that someone will become a white‐collar criminal. Given that no other similar research exists, this paper may help guide future researchers who are also attempting to solve this complex problem.     

Stress in youth sport: A developmental investigation of tennis parents

ObjectiveThis study investigated the stage-specific stressors experienced by British tennis parents whose children were situated either in the sampling, specializing or investment stages of participation in the sport [Côtè, J. (1999). The influence of the family in the development of talent in sport. The Sport Psychologist, 13, 395–417].Design and methodA qualitative design was employed with semi-structured interviews conducted with twenty two British tennis parents; six parents representing each of the first two stages of sports participation and ten representing the investment stage. Data was analyzed through a process of inductive content analysis following the method proposed by Miles and Huberman [Miles, M. B., & Huberman, A. M. (1994). Qualitative data analysis. London: Sage]. Data matrices were developed for each category of parent to allow for the comparison of the data between themes.Results and conclusionThree general dimensions of parental stressor emerged: Organizational, Competitive and Developmental. Organizational stressors included demands related to finance, time, training and coaching, and governing body systems; competitive stressors related to behavior, performance and morality-related issues associated with their child's matches; and developmental stressors centered on educational issues, uncertainty of tennis transitions, and future decision making. While sampling stage parents encountered few developmental stressors compared to later stage parents, a range of competitive stressors were highly prominent. Organizational stressors were particularly foremost for specializing and investment stage parents. Implications are discussed with reference to further research into the parental stress process and to the importance of stage-specific parent education initiatives.
