Conditioned leg movement in the cat with massed trials,trace conditioning,and weak US intensity

Six male cats served as subjects in a classical conditioning experiment designed to assess the development of an overt conditioned response with experimental parameters that had been demonstrated to produce conditioning of neuro-electrical activity in immobilized cats. The subjects were physically restrained by means of an adjustable full-body cast during the experimental sessions which consisted of 75 habituation trials (light flash alone) followed by 225 trials with light and shock paired in a trace conditioning manner, and 75 additional extinction trials (light alone). The subjects were divided into two groups, and three different experimental sessions were given to each on three consecutive days. Group I received low US intensity (18 v) conditioning on the first day, high US (45–85 v) conditioning on Day 2 and pseudoconditioning on Day 3. Group II received the same sessions, but in a pseudoconditioning —high US—low US order. The results indicated that a conditioned leg movement was produced when the CS was paired in a trace conditioning fashion with either the high or low intensity shock US. The development of the conditioned leg movement across trials was found to be very similar to that of the conditioned neural activity in a previous study using comparable stimuli and procedures.     

Psychological correlates of the French sound system

Six samples of CCVC phoneme sequences were devised to represent linguistically specifiable distances from existing French words, distance being measured in terms of number of substitutions needed to make an existing French word. Fifty-four native speakers of French rated the sound sequences for their subjective proximity to French, using ungraded rating scales. Results showed a general correspondence between the linguistic and psychological measurements, although certain phoneme sequences did not follow the predicted order. These were examined to see if their displacement could be attributed to the number of different French words reached through substitutions.     

Undergoing,Mystery, and Half-Knowledge: John Dewey’s Disquieting Side

In this article I argue that Dewey, throughout his work, conducted a systematic dismantling of the concept of rationality as mastery and control. Such a dismantling entails, at the same time, the dismantling of the auto-grounded subject, namely, the subject that grounds itself in the power to master experience. The Deweyan challenge to Western ontology goes straight to the core of the subject’s question. Dewey not only systematically challenged the understanding of thinking as a process consciously managed by the subject but also conceived of thinking as an event rather than a process—something that occurs in us rather than something intentionally staged by a reflective subject. Such a twofold dismantling of rationality and subject rather than a flow in a nihilistic/relativistic account of education results in a reinforcement of education that must be understood not so much as the attempt to understand and predict experience but as the means to create new, unpredictable experience. As a result, education, for Dewey, is grounded on, moved by, and directed at uncertainty. Education, in a sense, engenders uncertainty.     

Psychometric properties of the General Health Questionnaire-12 in a sample of Hong Kong employees

The General Health Questionnaire-12 (GHQ-12) is a widely used instrument for measuring psychological strain, but the factor structure of the GHQ-12 is inconclusive. The present study examined one-factor, two- and three-factor models of the GHQ-12 using structural equations modelling in a longitudinal data-set of Hong Kong employees. The findings supported a two-factor model consisting of a ‘Social Dysfunction’ factor measured by three items, and an ‘Anxiety/Depression’ factor measured by four items. Implications and limitations are discussed.     

Coping styles in adults with cystic fibrosis: implications for emotional and social quality of life

As life expectancy increases, interest has grown surrounding the factors that may influence quality of life (QOL) for people with cystic fibrosis (CF). The aim of the current study was to examine which specific coping styles were positively or negatively associated with social and emotional QOL in a CF sample. One hundred and twenty-two respondents aged 18 and over were recruited through an online support group. Respondents completed the ‘CF Questionnaire-Revised (CFQ-R)’ and the ‘Brief COPE’. The CFQ-R is a disease-specific instrument designed to measure the impact of CF on nine QOL domains and the Brief COPE is a 28 item questionnaire which assesses 14 coping scales. A multivariate regression model revealed that higher substance abuse and disengagement was associated with lower emotional QOL whereas greater use of religion, instrumental coping and acceptance was positively associated with emotional QOL. Active coping was linked to better social QOL and a negative association was reported between distraction coping with both emotional and social domains. Given the burden of CF, ascertaining which factors enhance or diminish emotion and social well-being is now an integral component of QOL research. The current findings may therefore have value in informing clinical interventions which aim to cater for the psychological needs of individuals with CF.     

The 2014 Agreed Statement on Christology of the Churches of the Anglican Communion and the Oriental Orthodox Churches: a Catholic review

This article discusses the sources of the 2014 Agreed Statement on Christology, which include not only the 433 Formula of Union and the teaching of St Cyril of Alexandria but also some language from the Council of Chalcedon (451), the Second Council of Constantinople (553), and the Third Council of Constantinople (680–681). It also examines the rejection of Eutychianism and Nestorianism, as well as the Anglican Christology represented by Richard Hooker and the firm connection drawn between the hypostatic union and Christ’s work of salvation. The article also presents the text in comparison and contrast with two Christological declarations shared by the Roman Catholic Church and the Coptic Pope Shenouda III (1973) and the Assyrian Church of the East (1994).     

The Role of Non-Numerical Stimulus Features in Approximate Number System Training in Preschoolers from Low-Income Homes

Recent findings have suggested that adults’ and children’s approximate number system (ANS) acuity may be malleable through training, but research on ANS acuity has largely been conducted with adults and children who are from middle- to high-income homes. We conducted 2 experiments to test the malleability of ANS acuity in preschool-aged children from low-income homes and to test how non-numerical stimulus features affected performance. In Experiment 1, mixed-effects models indicated that children significantly improved their ratio achieved across training. Children’s change in probability of responding correctly across sessions was qualified by an interaction with surface area features of the arrays such that children improved their probability of answering correctly across sessions on trials in which numerosity conflicted with the total surface area of object sets significantly more than on trials in which total surface area positively correlated with numerosity. In Experiment 2, we found that children who completed ANS acuity training performed better on an ANS acuity task compared with children in a control group, but they only did so on ANS acuity trials in which numerosity conflicted with the total surface area of object sets. These findings suggest that training affects ANS acuity in children from low-income homes by fostering an ability to focus on numerosity in the face of conflicting non-numerical stimulus features.
