Critical review of state-trait curiosity test development

State-trait research offers good prospects for new insights into human curiosity. It has already generated development of new scales, and several studies have been undertaken independently in Australia and the United States. This paper critically reviews the development of state [C-State] and trait [C-Trait] curiosity scales, pointing out methodological limitations in the existing state-trait curiosity studies. Specific recommendations are made with the aim of enhancing future research in this area.     

The influence of context and UCS intensity on the UCS preexposure effect in a flavor aversion paradigm

Three studies were conducted to evaluate the influence of environmental context and UCS preexposure intensity on the acquisition of a flavor aversion. In the first study, rats were exposed to two UCS-alone presentations at one of three dose levels of LiCl. The rats were given the two UCS preexposures in one of two contexts (familiar or novel). Following the UCS-alone treatment, all of the subjects received two pairings of sucrose and LiCl (1.25 meq) in the familiar context. Animals receiving UCS preexposures in the same context as used during conditioning consumed significantly more sucrose than did saline control animals. In contrast, the influence of prior UCS preexposure was not evident when UCS preexposure was experienced in a context different from that experienced during conditioning. In Experiment 2, all animal received UCS preexposure and conditioning in the novel room. Animals received either two or four preexposures at 0, 1.25, or 3.75 meq dose of LiCl. Two UCS preexposures at 3.75 meq dose produced a stronger UCS preexposure effect than did the 1.25 meq dose. Animals in Experiment 3 received two exposures to either 0-, 1.25-, or 3.75-meq LiCl in one of two contexts, followed by conditioning with the 1.25-meq LiCl dose in the same context as preexposure. Greater UCS interference occurred in animals preexposed to LiCl in the novel rather than familiar environment, with no specific dose effects in either context. These observations are discussed in terms of context blocking and generalization decrement models of the UCS preexposure effect.     

Language disorders in dementia of the Alzheimer type

The language profile of a group of 18 Alzheimer patients is documented and their performance on a standard aphasia test battery compared to a group of institutionalized, nonneurologically impaired control subjects matched for age, sex, and educational level. The Alzheimer patients scored significantly lower than the controls in the areas of verbal expression, auditory comprehension, repetition, reading, and writing. Articulation abilities were the same in each group. A language deficit was evident in all Alzheimer patients. The language disorder exhibited resembled a transcortical sensory aphasia. Syntax and phonology remained relatively intact but semantic abilities were impaired. The results support the inclusion of a language deficit as a diagnostic criterion of Alzheimer's disease.     

Mirror Self‐Recognition and Self‐Identification

That great apes are the only primates to recognise their reflections is often taken to show that they are self‐aware—however, there has been much recent debate about whether the self‐awareness in question is psychological or bodily self‐awareness. This paper argues that whilst self‐recognition does not require psychological self‐awareness, to claim that it requires only bodily self‐awareness would leave something out. That is that self‐recognition requires ‘objective self‐awareness’—the capacity for first person thoughts like ‘that's me’, which involve self‐identification and so are vulnerable to error through misidentification. This objective self‐awareness is distinct from bodily or psychological self‐awareness, requires cognitive sophistication and provides the beginnings of a more conceptual self‐representation which might play a role in planning, mental time travel and theory of mind.     

Psychometric appraisal of Eysenck's revised Psychoticism scale: a cross-cultural study

Psychometric characteristics of Eysenck's revised P scale were studied in a cross-cultural research. The Spanish version of the Eysenck Personality Questionnaire-Revised (EPQ-R) was administered to a Spanish sample of 527 males and 583 females. Maximum-likelihood factor analyses of the item intercorrelations and Direct Oblimin rotations of the extracted factors were carried out separately for males and females. The results revealed four factors identified as psychoticism (P), extraversion (E), neuroticism (N) and dissimulation/conformity (L). Internal consistency and test–retest reliability coefficients were satisfactory and very similar to the ones found in the original study. Skewness and kurtosis of the P scale distribution were closer to normal than on the original British revised P scale.     

Effects of self-monitoring and subsequent fading of external prompts on the on-task behavior and task productivity of elementary students with moderate mental retardation

This study investigated the effectiveness of self-monitoring on the on-task behavior and vocational production rates of 5 elementary students with moderate mental retardation during biweekly pre-vocational workshop sessions. They were taught to use a recording form to monitor their behavior and were cued to monitor by audiotaped tones. A multiple-baseline design across tasks was used to demonstrate a functional relationship between self-monitoring and both on-task behavior and task productivity. Once this relationship was demonstrated, the monitoring form and audiotape were withdrawn through fading procedures. Results indicated that (a) self-monitoring increased both on-task behavior and vocational task production rates, (b) performance gains maintained while cues and monitoring forms were withdrawn, and (c) gains maintained over several weeks in the absence of prompts (i.e., forms and tones).     

Treating elopement without extinction in a preschool setting

Elopement is a prevalent and dangerous behavior that is common with children with autism spectrum disorder (ASD). Due to safety, logistics, and effort on the part of stakeholders, recent research has emphasized the need for treatments that do not include extinction or response blocking. Using a multiple-baseline-across-functions design, we successfully decreased elopement with functional communication training, without additional treatment components, for one function but needed to add an additional treatment component (response blocking) for the second function for a 4 year-old boy with ASD who engaged in elopement in a preschool setting. We highlight contributions to the literature on elopement as well as directions for future research.

Attending Religious Services and Its Relationship with Coronary Heart Disease and Related Risk Factors in Older Adults: A Qualitative Study of Church Pastors’ and Parishioners’ Perspectives

A qualitative study was undertaken to explain findings of a cross-sectional study of Canadian Community Health Survey (CCHS) 4.1 data showing older persons who attend religious services more than once a week, compared to persons who do not attend at all, have lower prevalences of coronary heart disease (CHD), diabetes and high blood pressure. Twelve semi-structured interviews with ordained pastors and three focus groups with older parishioners from Canadian churches were conducted. Interviews were transcribed and analyzed for emergent themes through a process of direct content analysis. All participants claimed that religious service attendance (RSA): (1) enhances mental health; (2) provides social support and activities; and (3) promotes health and lifestyle behaviours that lower CHD risk. These three themes appear to be underlying mechanisms that help to explain the inverse association between RSA and the prevalence of adverse health outcomes found in the CCHS 4.1 data.
