The perceptual span and peripheral cues in reading

Skilled readers read passages that were displayed on a Cathode Ray Tube controlled by a computer. The readers' eye movements were monitored and certain critical words were changed by the computer as the eye was in motion. The experimental technique utilized in the study provided data on how wide the area is from which a reader acquires information during a fixation in silent reading. The results also delineate different types of visual information that are acquired from various areas within the perceptual span. It was found that a reader was able to make a semantic interpretation of a word that began 1–6 character spaces from his fixation point. When he fixated 7–12 character spaces prior to a word, he was able to pick up such gross visual characteristics as word shape and initial and final letters. It was concluded that the skilled reader is able to take advantage of information in the periphery. However, the size of the area from which he does is rather small.     

An experimental test of three choice shift hypotheses*

The present experiment pitted three choice shift hypotheses against each other in an attempt to eliminate one or more of the hypotheses and find support for those remaining. Ss responded three times to the 12 CDQ items, once as a pretest and twice following presentation of homogeneous sets of three arguments which advocated either a risky or a cautious position. The risk-as-value, relevant arguments, and conformity/attitude change hypotheses generated three separate predictions for the Ss' responses. Results mirrored the prediction of the relevant arguments hypothesis: New information, whether contained in cautious or risky arguments, caused a shift toward the type of argument presented. The risk-as-value and the conformity/attitude change hypotheses could not explain the present data.     

Escape from an effortful situation

This experiment investigated the tendency to escape from a situation requiring effortful responding. Five human subjects responded in a situation where the response mechanism required 20-lb force to operate; responses were reinforced according to a variable-interval schedule. A subject escaped from this situation by emitting a vocal response which produced a 60-sec “easy period”. During the easy period the reinforcement contingency was switched to a response mechanism requiring 1 lb to operate. It was found that: (1) Escape responding could be conditioned and maintained by producing the easy period; the easy period did not maintain escape responding when the force requirement in the normal situation was equated with it. (2) The rate of escape responding was a function of the magnitude of the force normally required. (3) When easy periods were scheduled after fixed ratios, pausing from the end of the previous easy period to the first escape response was noted. It was concluded that a situation requiring high-force responding is a negative reinforcer. The pattern of fixed-ratio responding suggests that this reinforcer produces typical schedule control in human subjects.     

Youth Self-Views,Coping with Stress,and Behavioral/Emotional Problems: The Role of Incremental Self-Theory

Previous research has established associations between stress and coping processes and internalizing and externalizing problems among adolescents and emerging adults. The purpose of the present study was to integrate this literature with research demonstrating the importance of self-theory—views that individuals hold about themselves and their abilities. We examined the extent to which self-theory may influence both coping processes and internalizing and externalizing problems among adolescents and emerging adults. Using moderated mediation, we tested whether coping serves as a mechanism through which self-theory of both intelligence and personality influences internalizing and externalizing problems among adolescents and emerging adults. One hundred and forty participants (adolescents aged 14–17; emerging adults aged 18–30; 60 % female; 8.5 % ethnic minority) completed questionnaires on self-theory, coping responses, and behavioral/emotional problems. Results of moderated mediation analyses were consistent with coping as a mechanism through which self-theory influences psychopathology symptoms such that more malleable beliefs are associated with increased productive coping strategies and lower levels of internalizing and externalizing problems. The current findings also indicate that these associations were significant for adolescents but not for emerging adults. Although cross-sectional, findings suggest that fostering malleable beliefs among adolescents may increase the use of productive coping strategies and positively influence adjustment.     

The Munroe-Meyer Approach: Continuous Integration of Didactic Instruction,Research, and Clinical Practice

Increased demand for applied behavior analysis (ABA) services has increased the need for additional masters-level practitioners and doctoral-level academicians and clinical directors. Based on these needs, the University of Nebraska Medical Center’s (UNMC) Munroe-Meyer Institute has developed a PhD program. The academic structure at UNMC allowed us to create our PhD program in a relatively quick and efficient manner. Our PhD program has many unique features, including (a) close integration of didactic instruction with clinical and research training provided by leading experts in ABA in which students immediately apply concepts introduced in the classroom during coordinated clinical and research practica; (b) structured grant writing training in which students learn to write and submit an NIH-level grant; (c) financial support in the form of a stipend of $23,400 per year, free health benefits, and a full-tuition waiver for up to 12 credits per semester for UNMC courses (a benefits package worth approximately $50,000 per year for an out-of-state student); and (d) encouragement and financial support to present papers at local, regional, and national behavior analysis conferences.     

Leaping to Conclusions: Why Premise Relevance Affects Argument Strength

Everyday reasoning requires more evidence than raw data alone can provide. We explore the idea that people can go beyond this data by reasoning about how the data was sampled. This idea is investigated through an examination of premise non‐monotonicity, in which adding premises to a category‐based argument weakens rather than strengthens it. Relevance theories explain this phenomenon in terms of people's sensitivity to the relationships among premise items. We show that a Bayesian model of category‐based induction taking premise sampling assumptions and category similarity into account complements such theories and yields two important predictions: First, that sensitivity to premise relationships can be violated by inducing a weak sampling assumption; and second, that premise monotonicity should be restored as a result. We test these predictions with an experiment that manipulates people's assumptions in this regard, showing that people draw qualitatively different conclusions in each case.     

Mentoring and Peer-led Interventions to Improve Quality of Life Outcomes among Adolescents with Chronic Illnesses

Advancing adolescent medicine has resulted in increased survival rates for life-limiting health conditions that are now considered chronic conditions. Due to the increased rates of chronic illnesses, the broad outcomes of community-based programs for adolescents with these illnesses need to be examined. Therefore, the present study seeks to examine community-based, mentoring and peer-led programs that have a social support component to increase quality of life outcomes for adolescents with chronic illnesses. A comprehensive literature review was conducted to identify articles that included a social support component to increase quality of life outcomes for adolescents with chronic illnesses. Six articles were included in the narrative analysis. Programs were divided into two types of interventions: mentoring/coaching (n?=?3) and peer-led interventions (n?=?3). A summary of each study was developed and main themes from each intervention were identified by the research team. This review found six community-based peer-led and mentoring interventions that incorporated a social support component to improve the quality of life of adolescents with chronic illnesses. Critical components for a peer-led or mentoring intervention should include social support components such as health coaching and mentoring by peers or adults. Since the nature of chronic illnesses is lengthy in duration, social support research translated into practice may offer adolescents who have any of these illnesses a means to improve their psychosocial outcomes. The interventions outlined in this present review have yielded promising results. Recommendations for future studies are included.     

The positive contributions of hope to maintaining and restoring health: An integrative,mixed-method approach

A link between hope and physical well-being has long been suspected. To shed further light on this issue, an integrative theory of hope was used to design three health-related studies. In studies one and two, an integrative hope scale was used. In study one, greater hope was associated with depth of commitment to a healthier diet and regular exercise. In study two, the integrative hope scale was associated with a wider array of health behaviors as compared to a standard goal-oriented hope scale. In study three, a hope-centered content analysis of testimonies provided by long-term breast cancer survivors revealed a strong reliance on attachment and spirituality, dimensions typically neglected in psychological studies of this [hope] construct. An integrative approach to hope offers a framework for further research on hope and health as well as a blueprint for developing positive interventions to sustain and restore physical well-being.
