Throughput: A simple performance index with desirable characteristics

Throughput is a corrected response rate measure giving the number of successes per unit of discretionary time. It is a simple but general index applicable to psychomotor, behavioral, and cognitive tasks in which response times are measured. This measure has several attractive features: (1) It allows comparisons to be made across various tasks in which speed and accuracy are meaningful and measurable, independently of temporal differences in hardware, software, and procedures; (2) under conditions in which both speed and accuracy decline (or improve), throughput will be a more sensitive index of performance than either alone will be; and (3) in those tasks in which the speed—accuracy trade-off phenomenon operates, throughput will tend to be relatively less variable than either component alone will be. The measure allows both behavioral and information-processing interpretations of data and may be useful as a simple composite index, a measure of effectiveness or of cognitive consistency in studies investigating performance degradation or enhancement.     

The "style scheme" grounds perception of paintings

We studied the formation of style scheme (identification of the style that characterizes an artist) presenting 100 participants aesthetic visual stimuli. Participants were Spanish university students who volunteered: 72 women, 28 men of mean age 22.8 yr. Among those 50 were enrolled in History of Art and 50 students in Psychology. Stimuli belonged to different categories--High Art (pictures of well-known artists, like Van Gogh)/Popular Art (decorative pictures like Christmas postcards) and Representational (pictures with explicit meaning content, like a landscape)/Abstract (pictures without explicit meaning content, like Pollock's colored stains). Analysis using Signal Detection Theory techniques focused on how participants discriminate representational and abstract pictures. With High Art stimuli, participants can better discriminate representational paintings than abstract ones. However, the difference in discrimination between representational and abstract pictures diminishes among participants studying History of Art. It seems that prior education in art favors forming style schemes and to some extent enables the participant to detect the "meaning" in High Art abstract paintings.     

The prophetic nature of pastoral counselling

The role of pastoral counselling is explored in the light of the increasing interest among secular therapists in spirituality and the escalation in the number of clients presenting themselves with spiritual issues. Definitions are offered of spirituality, sexuality and religion as well as of pastoral counselling itself. The development of pastoral counselling is contrasted with the upsurge of Christian counselling in the latter years of the 20th century.The central influence of Carl Rogers is examined and it is argued that his late embracing of the spiritual dimension makes him, once more, a potential source of inspiration for pastoral counsellors in the years ahead. The critical tasks of integrating science and religion and of communicating across inter-faith boundaries require both an emphasis on contemplative and mystical experience and a radically evolving theology. Rogers' 'person of tomorrow' is seen as a possible blueprint for the pastoral counsellor of the future who can be assured of a difficult path and much hostility and misunderstanding.     

The Care and Development of Children Living in Contexts of Poverty

Human development is determined by both genetic and environmental factors, especially during early childhood. Recently, research has indicated that the circumstances surrounding poverty can significantly influence children’s development. In this study, we aimed to measure the developmental level of children living in low-income, rural areas in northern Colombia. A total of 629 children (aged 0–5 years) were assessed using the Battelle Developmental Inventory. Results indicated that 17?% of the participants had a general developmental delay for their age group. This was especially true for scores on cognitive development (35.5?%) and communication (21.5?%). Moreover, the number of children with developmental delay increased at 6 months of age and continued to increase after 1 year in the communication and cognitive domains. The findings of this study suggest that impoverished social contexts—such as the one studied herein—offer opportunities that favor the development of the social domain, but restrict the development of the cognitive domain. Therefore, to promote cognitive development, individuals within children’s environment need to actively and intentionally stimulate them. Thus, there is a need for interventions that will improve environmental conditions; especially those that will help parents improve their caregiving practices and train educational staff to recognize and respond to the stimulation needs of children, especially those developmental domains that are affected by the environment.     

Concept Appraisal

This paper reports the first empirical investigation of the hypothesis that epistemic appraisals form part of the structure of concepts. To date, studies of concepts have focused on the way concepts encode properties of objects and the way those features are used in categorization and in other cognitive tasks. Philosophical considerations show the importance of also considering how a thinker assesses the epistemic value of beliefs and other cognitive resources and, in particular, concepts. We demonstrate that there are multiple, reliably judged, dimensions of epistemic appraisal of concepts. Four of these dimensions are accounted for by a common underlying factor capturing how well people believe they understand a concept. Further studies show how dimensions of concept appraisal relate to other aspects of concepts. First, they relate directly to the hierarchical organization of concepts, reflecting the increase in specificity from superordinate to basic and subordinate levels. Second, they predict inductive choices in category-based induction. Our results suggest that epistemic appraisals of concepts form a psychologically important yet previously overlooked aspect of the structure of concepts. These findings will be important in understanding why individuals sometimes abandon and replace certain concepts; why social groups do so, for example, during a “scientific revolution”; and how we can facilitate such changes when we engage in deliberate “conceptual engineering” for epistemic, social, and political purposes.     

EFFECTS OF ACADEMIC DEGREE AND DISCIPLINE ON RELIGIOUS AND EVOLUTIONARY VIEWS IN CHILE AND COLOMBIA

Relationships between degree/area of academic formation and religious and Darwinian views are controversial. This study aimed to compare the religious beliefs and acceptance of Darwinian evolution between two contrasting South American scientific communities (Chile and Colombia), accounting for different degrees and areas of academic formation. In 2018, 115 last year bachelor students (surveyed as freshmen in 2014 for a previous study) from Chile, and 283 first/last year bachelor students, graduate students, and professors from Colombia, all belonging to biology, chemistry, or physics, were surveyed. Chilean students/faculty were significantly more agnostic/atheist, more accepting of Darwinian evolution, and less creationist than their Colombian counterparts. Academic degree and area differently affected these views in both countries, as only in Chile there was a clear tendency among biologists and physicists with higher degrees to hold less religious and creationist views. Marked differences between the history, socioeconomic contexts, and especially in high school and university curricula of both countries might explain these results.     

A Systematic Review and Quantitative Analysis of Interteaching

Interteaching is a behavioral teaching method that departs from the traditional lecture format (Boyce & Hineline in BA 25:215–226, 2002). We updated and expanded previous interteaching reviews and conducted a meta-analysis on its effectiveness. Systematic searches identified 38 relevant studies spanning the years 2005–2018. The majority of these studies were conducted in undergraduate face-to-face courses. The most common independent variables were manipulations of the configuration of interteaching or comparisons to traditional-lecture format. The most common dependent variables were quiz or examination scores. Only 24% of all studies implemented at least five of the seven components of interteaching. Prep guides, discussions, record sheets, and frequent assessments were the most commonly implemented. Meta-analyses indicated that interteaching is more effective than traditional lecture or other control conditions, with an overall large effect size. Furthermore, variations in the configuration of the interteaching components do not seem to substantially limit its effectiveness, as long as the discussion component is included. Future research informed by the present review includes: (a) investigating the efficacy of interteaching in additional academic areas, online environments, workplace training, and continuing education, (b) testing alternative outcome measures, generalization, and procedural integrity, (c) conducting systematic component analyses, and (d) measuring social validity from the instructor’s perspective.

     

The Confluence of Psychiatric Symptoms and Neurodegenerative Disease: Impact on Genetic Counseling

Hereditary neurodegenerative diseases can present with a psychiatric prodrome that overlaps with psychiatric symptoms that are not primary to these diseases. When individuals present for predictive testing while experiencing such symptoms, clinicians including genetic counselors, must proceed with caution and evaluate each situation on a case-by-case basis. Legitimate reasons may exist for moving forward with testing. Additionally predicting the consequences of testing is unrealistic so that the clinicians must do their best to prepare patients for both positive and negative results. A multidisciplinary team following the Huntington disease protocol remains the gold standard care for predictive testing for such patients. We discuss 3 case histories that demonstrate the complex nature of genetic counseling and testing in the presence of psychiatric symptoms, whether emanating from the disease itself or the results of living in an affected family.
