Some early similarities and later differences between Bertrand Russell and B. F. Skinner

B. F. Skinner credited Bertrand Russell with converting him to behaviorism and with writing one of the books that most influenced him. Particularly in Skinner's early work, there are similarities between Skinner and Russell that extend across mathematics, determinism, positivism, verbal behavior, future communities, evolution, and pragmatism. Later, Skinner's views changed, and he parted company with Russell in most of these areas. Perhaps the most dramatic and fundamental departure came when Skinner embraced pragmatism, which Russell said he "hated." However, there was a time during which Russell wrote favorably of pragmatism as a view for science. Although the similarities between Skinner and Russell may have resulted from common cultural influences, Russell appears to deserve credit for leading Skinner into the stimulus-response behaviorism of two-term necessities; he may also deserve some credit for helping to lead him out of it and into the selectionist behaviorism of three-term contingencies.     

Rapidly learned song-discrimination without behavioral reinforcement in adult male zebra finches (Taeniopygia guttata)

Zebra finches communicate via several distinct vocalizations, of which song is the most studied. Behavioral observations indicate that adults are able to discriminate among the songs of different conspecific individuals. In the wild, zebra finches live in structured but mobile colonies, and encounter new individuals on a frequent basis. Thus it seems plausible that adult finches might have the capacity to recognize and remember new songs they encounter on a single day, but this has never been directly tested. Here we devised a simple observational assay to determine whether adult male zebra finches show recognition of a song they have heard repeatedly from taped playbacks, over a single three hour period the day before. We quantified the rate of production of six discrete behaviors (short calls, contact calls, singing, short hops, long hops, and beak swipes) made by adult male zebra finches as they listened to the playbacks. At the onset of song playback, all birds suspended these behaviors and sat silently-occasionally moving their heads. Then, after a measurable period ("response latency"), the birds resumed these activities. We observed that the response latency was long (approximately 10 min) when birds were hearing a particular song for the first time. The response latency was much shorter (approximately 1-2 min) when the birds had heard the same song the day before. Thus, functional song memories must result from as little as 3 h of passive song-exposure. These results suggest that ongoing song learning may play a natural role in the daily life of adult zebra finches, and provide a behavioral reference point for studies of molecular and physiological plasticity in the adult auditory system.     

Rolling away the stone: post-abortion women in the Christian community

This article seeks to bring to awareness and address the issues of a neglected group of people in need of pastoral care: women who have had an abortion. It offers some commentary regarding what many women experience following an abortion, focuses on the story of a specific woman, and goes on to offer a biblical perspective for a pastoral response to their needs. Responses to the article are offered by a healthcare chaplain and a seminary professor.     

Personal Identity, Reductionism and the Necessity of Origins

A thought that we all entertain at some time or other is that the course of our lives might have been very different from the way they in fact have been, with the consequence that we might have been rather different sorts of persons than we actually are. A less common, but prima facie intelligible thought is that we might never have existed at all, though someone rather like us did. Arguably, any plausible theory of personal identity should be able to accommodate both possibilities. Certain currently popular Reductionist theories of personal identity, however, seem to be deficient in precisely this respect. This paper explores some Reductionist responses to that challenge.

An exploration of links between early parenting experiences and personality disorder type and disordered personality functioning

Reports of early parenting were assessed using two measures, the Parental Bonding Index (PBI) and the Measure of Parenting Style (MOPS), in a sample of 265 patients with DSM-defined major depressive disorder. Psychiatrists then rated the extent to which sample members evidenced the personality "styles" underpinning 15 separate personality disorders, returning personality vignette scores. The extent of disordered functioning was also assessed across "parameters" and "domains" by psychiatrists, referrers, and family members, using a range of measures. Those with higher scores on vignettes measuring borderline, anxious, depressive, and self-defeating personality style rated parents as uncaring, overcontrolling, and abusive. When vignettes were consolidated into scores akin to the DSM clusters, the most consistent links between perceived dysfunctional parenting were with the Cluster C (anxious), and Cluster B (dramatic) styles and were nonsignificant for Cluster A (eccentric) style. Meeting criteria for an increasing number of personality disorder clusters was associated with increasing levels of adverse parenting. Multiple regression analyses indicated that disordered functioning (as assessed by the three independent rater groups) was most distinctly associated with paternal indifference and maternal overcontrol.     

Prehension in children and adults: The effects of object size

Studies of visually goal-directed arm movements in adults have shown that various task constraints such as intention, context, and object properties affect different kinematic characteristics of the movement components (Jeannerod, 1984; MacKenzie et al., 1987; Marteniuk et al., 1987, 1990; Paulignan et al., 1991; Soechting, 1984). The purpose of the present study was to compare the effects of varying object size on the kinematics of reaching and grasping in both children and adults. Five children aged 9–10 years and five adults aged 18–24 years reached for and grasped three different sized cubes. Results revealed that object size had the same effect on the planning and control of reaching and grasping movements in children as in adults. Unlike adults, however, children in this age range spent more time in deceleration and reached peak aperture much later in the movement trajectory. The results were interpreted as immature integration of the visual and proprioceptive systems in 9–10 year olds. The implications of these findings for further examining developmental trends in prehension are discussed.PsycINFO classification: 2330     

Interrelationships between temperament characteristics and first-grade teacher-student interactions

The relationships between temperament characteristics and first-grade teacherstudent interaction were investigated. It was hypothesized that the temperament characteristics of Adaptability and Approach/Withdrawal would be potent predictors of teacher-student interactions since they had been found previously to be strong predictors of children's emotional and behavioral adjustment to school. The teachers of 105 first-grade children completed temperament questionnaires during the early part of the academic year, and their interactions with the children were observed soon thereafter. The teacher temperament ratings were factor-analyzed, and regression models were generated to predict classroom interactions. The study's hypothesis was supported, and three separate temperament dimensions were found to be predictive of classroom interactions. Suggestions are made for future extensions of the findings.     

Toward a theology of maturity in pastoral care

Popular theology has neglected a developmental perspective and has reinforced the concepts of human inadequacy and divine self-sufficiency. This has tended to keep persons in a state of infantile dependency on a super-father-figure God. Pastoral care, with its concern for the person and its commitment to the processes of growing and maturing in the self and in relationships, needs a theological frame of reference which positively reinforces a developing maturity in relation to God, as well as self and others.Formerly Associate Professor of Psychology of Religion and Pastoral Care at Midwestern Baptist Theological Seminary, Dr. Woodruff is Executive Director of the Peninsula Pastoral Counseling Center, Hampton, Virginia.     

A Preventive Approach to School Violence and Vandalism: An Experimental Study

School violence and vandalism are at crisis level. The investigators attempted to employ strategies that would attack identified procreators of school violence and vandalism existing within our schools. The effects of these strategies on vandalism costs, student attendance, off-task and disruptive behaviors, and on various kinds of positive teacher-student contacts were investigated in 19 elementary schools. Results indicated that the dollar costs of vandalism and frequency of inappropriate student behaviors decreased more in experimental than in control schools. Student attending and positive teacher-student contacts improved, or remained higher, in the experimental than in the control schools.
