Pausing phenomena: Influence on the quality of instruction

This report summarizes work of 7 years on the influence of a variable called “wait-time” on the development of language and logic of children taking part in elementary science programs. Analysis of over 300 classroom tape recordings showed mean pauses to be on the order of 1 sec; that is, after a teacher asked a question, students had to begin a response within an average time of 1 sec. If they did not, the teacher typically repeated, rephrased or asked a different question, or called on others. A second wait-time is involved: when a student makes a response, the teacher normally reacts or asks another question within an average time of 0.9 sec. This study investigates the consequences of manipulating both species of wait-time. When mean wait-time of 3–5 sec is achieved through training, analysis of more than 900 tapes shows changed values on eight student variables: (1) the length of response (number of words) increases, (2) the number of unsolicited but appropriate responses increases, (3) failures to respond decrease, (4) incidence of speculative responses increases, (5) incidence of student-student comparisons of data increases, (6) incidence of evidence-inference statements increases, (7) frequency of student-initiated questions increases, and (8) the variety in type of verbal moves made by students increases. Servochart plots of recordings show that students discussing science phenomena tend to speak in bursts, with intervals of as much as 3–5 sec between bursts being fairly common provided they are not interrupted. The average post-student-response wait-time of 0.9 sec apparently intervenes between bursts to prevent completion of a thought. The classroom is conceptualized as a two-player game in which the quality of inquiry will tend to improve when there is a better equity in the distribution of moves between the players. The teacher is treated as one player and the collection of students as the second player. Changes in wait-time shift the game toward a more equitable state. Over time, a classroom or instructional group on the prolonged wait-time schedule undergoes certain spontaneous changes. Two teacher variables change: (1) response flexibility scores increase, and (2) teacher questioning patterns becomes more variable. There is some indication that teacher expectations for performance of students rated as relatively slow improves.     

Skills training in the long-term management of stress and occupational burnout

The current managed healthcare environment stresses brief and effective short-term therapy. However, often this short-term treatment does not lead to long-term behavioral changes and clients return to therapy many times for help with the same dysfunctional behavioral patterns. The main problem with these traditional forms of treatment is the assumption that clients have the basic skills to change their ineffective behaviors. Yet, many people lack the basic skills to manage our highly stressful society, and may take years to master new behavioral management skills. Examining the relationship between stress and coping, this study explored both short-and long-term approaches to behavioral change relative to occupational burnout, and focused upon the teaching of skills to manage stress. Subjects who participated in a 6-week stressmanagement program reported only temporary decreases in burnout, while those subjects who received 1-hour coping “refresher” sessions at 5 months, 11 months, and 17 months showed consistent decreases in burnout throughout a 2 1/2 year period. These results suggest that psychologists can be much more effective behavioral change agents through long-term approaches that emphasize teaching new skills to manage chronic behavioral problems. Given the changes in the health insurance industry and the way therapeutic services are provided, the field may need to rethink approaches that are grounded in personality theory and abnormal psychology to approaches that emphasize principles of learning theory.     

Perspectives from the Edge: Chaplains in Greater Boston, 1945–2015

We follow Bender et al.’s (Religion on the Edge: De‐Centering and Recentering the Sociology of Religion) call to study religion “on the edge” by looking at the work of chaplains, religious professionals who work outside of congregations. Rather than studying chaplains within a single type of institution—the military, healthcare, or other sectors—we shift the unit of analysis to geography, asking where chaplains in Greater Boston worked between 1945 and the present. Based on coverage in the Boston Globe, we find that chaplains, mostly men, worked across Greater Boston between 1945 and 2015. The majority were Catholic with frequent minorities of Protestants and Jews, and—after 1995—a few Buddhists, Muslims, and Humanists. Most worked in higher education, healthcare, and prisons. While much of the chaplains’ work seems improvisational and varied, we identify services related to ceremonies, bearing witness, and working around death as common occurrences across the venues where chaplains worked. To the extent that these patterns are evident in other cities, they suggest that chaplains have regularly been a quiet part of the religious landscape, that they are a consistent part of the institutional field, and that their work has more commonalities across sectors than previous studies suggest.     

Longitudinal Profiles of Girls’ Irritable,Defiant and Antagonistic Oppositional Symptoms: Evidence for Group Based Differences in Symptom Severity

Three subdimensions of ODD symptoms have been proposed –angry/irritable (IR), argumentative/defiant (DF) and antagonism (AN). This study tested whether longitudinal symptom trajectories could be identified by these subdimensions. Group-based trajectory analysis was used to identify developmental trajectories of IR, DF and AN symptoms. Multi-group trajectory analysis was then used to identify how subdimension trajectories were linked together over time. Data were drawn from the Pittsburgh Girls Study (PGS; N = 2450), an urban community sample of girls between the ages of five--eight at baseline. We included five waves of annual data across ages five-13 to model trajectories. Three trajectories were identified for each ODD subdimension: DF and AN were characterized by high, medium and low severity groups; IR was characterized by low, medium stable, and high increasing groups. Multi-trajectory analysis confirmed these subdimensions were best linked together based on symptom severity. We did not identify girls’ trajectory groups that were characterized predominantly by a particular subdimension of ODD symptoms. Membership in more severe symptom groups was significantly associated with worse outcomes five years later. In childhood and early adolescence girls with high levels of ODD symptoms can be identified, and these youth are characterized by a persistently elevated profile of IR, DF and AN symptoms. Further studies in clinical samples are required to examine the ICD-10 proposal that ODD with irritability is a distinct or more severe form of ODD.     

Assessing women's responses to sexual threat: validity of a virtual role-play procedure

This study evaluated the validity of a role-play procedure that uses virtual reality technology to assess women's responses to sexual threat. Forty-eight female undergraduate students were randomly assigned to either a standard, face-to-face role-play (RP) or a virtual role-play (VRP) of a sexually coercive situation. A multimethod assessment strategy was used to evaluate the efficacy of the role-play procedure in creating a realistic and immersive situation. Consistent with our hypotheses, women in the VRP condition exhibited greater negative affect and immersion than women in the RP condition. In addition, the level of assertive refusal in the VRP, but not the RP, condition differentiated between women with and without a prior history of sexual victimization. These findings provide evidence of the validity of a virtual role-play procedure for assessing women's responses in sexually threatening situations.     

Genetic Influence Helps Explain Variation in Human Fertility: Evidence From Recent Behavioral and Molecular Genetic Studies

To search for genetic influence on human fertility differentials appears inconsistent with past empirical research and prior interpretations of Fisher's fundamental theorem of natural selection. We discuss Fisher's theorem and give reasons why genetic influences may indeed account for individual differences in human fertility. We review recent empirical studies showing genetic influence on variance in fertility outcomes and precursors to fertility. Further, some of the genetic variance underlying fertility outcomes overlaps with that underlying fertility precursors. Findings from different cultures, different times, different levels of data, and both behavioral and molecular genetic designs lead to the same conclusion: Fertility differentials are genetically influenced, and at least part of the influence derives from behavioral precursors that are under volitional control, which are themselves genetically mediated.     

Correlation of eye color on self-paced and reactive motor performance.

Researchers continue to examine the distinctiveness of motor performance by dark- versus light-eyed individuals. Dark-eyed individuals generally perform better at reactive type tasks (boxing, hitting a ball, defensive positions in football, rotary pursuit), while light-eyed individuals perform better at self-paced tasks (bowling, golf, pitching baseballs). Subjects performed two tasks, rotary pursuit and ball tossing (with light and dark background). Eye color (light or dark) and accuracy of performance were recorded for each subject. No significant difference was found between eye color and performance on the pursuit rotor (reactive activity). A significant difference was found between men's and women's performance in throwing a ball (self-paced activity) at a light-colored background.     

Academic achievement in Blacks and Whites: Are the developmental processes similar?

Genetic and environmental influences on academic achievement were investigated in four groups of siblings: (1) White full siblings, (2) White half-siblings, (3) Black full siblings, and (4) Black half-siblings. Our expectation was that the variances and covariances among three achievement tests would have the same structure across the four groups. This expectation was confirmed by a quantitative genetic model that imposed equal factor loadings across groups. This best fitting model had two factors: a Genetic factor representing genetic variation and a Shared Environment factor representing environmental differences among families. Reading recognition, reading comprehension, and mathematics tests all loaded on the Genetic factor, but primarily mathematics loaded on the Shared Environment factor. The quantitative genetic model was next fit to the achievement test means. Its successful fit suggested that the genetic and environmental influences involved in producing individual variation were the same as those producing the group-mean differences. In this sample, genes accounted for 66% to 74% of the observed group difference in verbal achievement and 36% of the difference in mathematics achievement. Shared environment accounted for the remainder, 34% to 26% of the difference in verbal achievement and 64% of that in mathematics achievement.     

Lamarque and Olsen on Literature and Truth

In Fiction, Truth and Literature , Lamarque and Olsen argue that if a critic claims or attempts to prove that the outlook of a work of literature is true or false, he is not engaging in literary or aesthetic appreciation. This paper argues against this position by adducing cases where literary critics discuss the truth or falsity of a work's view, when their opinions are obviously relevant to the work's aesthetic assessment. The paper considers in detail the way factual errors damage a work's aesthetic standing, and shows that Lamarque and Olsen's alternative account of the role of propositional truths in literature only looks plausible because it considers a restricted range of examples. Finally, it considers the role intention, date and genre play in discussions of the aesthetic damage done by literal falsehood.     

In the Eye of the Beholder? Parental Ratings of Externalizing and Internalizing Symptoms

Variations in ratings of externalizing and internalizing symptoms may contain a trait (i.e., shared view) component when behavioral symptoms that generalize across context are perceived and an individual view component when they are misperceived or when each informant has access to different symptoms. Using a LISREL model, we estimated the trait and the informant-specific, individual view components in parental ratings of externalizing and internalizing symptoms of adolescent siblings. The model demonstrated that mothers' and fathers' ratings contained a substantial individual view component (from 21% to 50% of total rating variance, depending on rater and trait). Except for fathers' ratings of internalizing symptoms (13%), parental ratings also contained a substantial trait component (42% to 58%). Mother's, father's, and child's ratings may be averaged to estimate a trait of externalizing. To estimate an internalizing trait, it may be best to combine just the mother's rating with the child's self-rating.
