Politics and Church: Byproduct or Central Mission?

One of the more intriguing paradoxes that has developed in mainline Protestantism over the last 30 years is that mainline clergy have become more politically active. Since the public politicking of mainline clergy in the late 1960s generated storms in the churches, why would clergy become more politically active over time? In this article, we adopt the theoretical structure of a benefit exchange between leaders and members initiated by Mancur Olson. We seek to determine the extent to which church members' appetites for political action by the clergy are shaped by a satiating selective benefit exchange or are driven largely by political compatibility. We propose that because of continued political disagreement between clergy and church members and considerable disapproval of clergy involvement in politics by church members, clergy politicking is allowed largely by the satisfaction of a selective benefit exchange.     

Recognition Memory in Pigeons for Stimuli Presented Repeatedly: Perceptual Learning or Reduced Associative Interference?

Todd and Mackintosh (1990) found that recognition memory of pigeons for pictures was better when the same pictures were used each session (a recency task) than when different slides were used (a novelty task); they attributed the superior performance on the recency task to perceptual learning. Three experiments explored two alternative accounts. One was that their use of a within-subject design could have allowed the strategy adopted in the recency task to influence adversely the strategy used in the novelty task. This possibility was ruled out by Experiment 1, which showed superior performance in the recency task when a between-subject design was used. A second account proposes that slide-reward associations formed (in both tasks) during first presentations of slides interfere with appropriate performance during second presentations (associative interference); in the recency task, however, the high long-term associative strength of the slides restricts the consequence of a single slide-reward pairing to a short-term effect, and associative interference occurs at short retention intervals only. This account was explored in Experiment 2, which found no evidence that increases in retention interval resulted in reduction of associative interference in the recency task, and in Experiment 3, where associative interference was shown to occur but was of comparable magnitude in the recency and novelty tasks. By elimination, the results support a perceptual learning interpretation.     

Affective-Evaluative Learning in Humans: A Form of Associative Learning or Only an Artifact?

The status of evaluative conditioning (EC) as a distinct form of associative learning was called in question by Field and Davey (1997, 1998, 1999), who argued that in the typical visual EC paradigm, nonassociative visual concept learning is responsible for the evaluative changes observed. Especially, the use of only within-subject control conditions instead of independent control groups was criticized. The present three experiments show (a) that EC effects can be demonstrated within another sensory modality than visual perception and (b) that EC effects are demonstrable in a between-subject design (including a successful replication attempt). A further result was that these EC effects do not require participants' conscious awareness. The data provide no support for an artifactual account of EC but suggest an interpretation of EC as a form of associative learning.     

Learning to sleep through the night: Solution or strain for mothers and young children?

Is the process of helping infants and young children learn to sleep through the night a solution to family sleep problems or does it exacerbate matters for mother and child? Retrospective and current accounts from a nonclinical, convenience sample of 102 mothers of preschool‐aged children provided information on sleep issues from early infancy through preschool age. Child, mother, and parenting characteristics, along with family sleep arrangements, were differentially related to the age at which children learned to sleep through the night and to the extent of difficulty that characterized this experience. Mothers who indicated more difficulty as their children learned to sleep through the night also reported more depressive symptoms and more strain in the mother–child relationship. Later age at sleeping through the night was more common among early bedsharers, but timing of sleeping through the night was not associated with preschool children's reported independence in several nonsleep domains. Sleep arrangements and the importance placed on sleeping through the night were the strongest contributors to variance explained in whether children learned to sleep through the night during infancy or toddlerhood. When advising parents about sleep interventions, practitioners should seek to understand whether families' parenting values fit their nighttime sleep practices.     

Learning lyrics: To sing or not to sing?

According to common practice and oral tradition, learning verbal materials through song should facilitate word recall. In the present study, we provide evidence against this belief. In Experiment 1, 36 university students, half of them musicians, learned an unfamiliar song in three conditions. In the sung-sung condition, the song to be learned was sung, and the response was sung too. In the sung-spoken condition, the response was spoken. In the divided-spoken condition, the presented lyrics (accompanied by music) and the response were both spoken. Superior word recall in the sung-sung condition was predicted. However, fewer words were recalled when singing than when speaking. Furthermore, the mode of presentation, whether sung or spoken, had no influence on lyric recall, in either short- or long-term recall. In Experiment 2, singing was assessed with and without words. Altogether, the results indicate that the text and the melody of a song have separate representations in memory, making singing a dual task to perform, at least in the first steps of learning. Interestingly, musical training had little impact on performance, suggesting that vocal learning is a basic and widespread skill.     

A Time for Silence? Its Possibilities for Dialogue and for Reflective Learning

From the beginning of history sounds have played a fundamentally important role in humanity’s development as ways of expression and of communication. However in contemporary western society, and indeed globally, we are experiencing an excess of speech and a relentless encouragement to expression. Such excess indicates a misunderstanding about what expression and dialogue should be. This condition encourages us to think about silence, solitude and contemplation and the role they might play in restoring the realm of personal understanding of the Self and of one’s authentic experience of the Other. The purpose of this article is to explore the potency of a silence that arises from our participation in the world. We present first some ideas about silence as a human phenomenon. This is followed by an examination of silence and language, an investigation of silence in dialogue, and of its educational implications. The article concludes by emphasising the value of silence as potency in itself, assisting in recovering the expressive powers of language. We argue that it is important to understand the positive status of silence in order to recognise and avoid repressive speech and to introduce its potential for reflective learning.     

Learning complex sequences: no role for observation?

Two experiments examined performance in a sequence learning task. Participants were trained on a repeating sequence which was presented as a visual display and learning was measured via the increase in reaction time to respond to a new sequence. Some participants made a response to each stimulus while others merely observed the sequence. In Experiment 1 participants responding to the display via a keypress showed learning, but those merely observing did not. Five possible reasons for the failure to find observational learning were considered and the Experiment 2 attempted to resolve these. This second experiment confirmed the findings of Experiment 1 in a non-spatial sequence display using a cover story which encouraged attention to the display but not rule-search strategies. The results are discussed in relation to applied and theoretical aspects of implicit learning. Received: 20 December 1999 / Accepted: 16 March 2000     

Learning and adult neurogenesis: survival with or without proliferation?

Recent high quality papers have renewed interest in the phenomenon of neurogenesis within the adult mammalian brain. Many studies now show that neurogenesis can be modulated by environmental factors including physical activity, stress, and learning. These findings have considerable implications for neuroscience in general, including the study of learning and memory, neural network plasticity, aging, neurodegeneration, and the recovery from brain injury. Although new light has been shed on this field, many contradictory findings have been reported. Here we propose two principle issues which underlie these inconsistencies, with particular focus on the interaction between learning and neurogenesis. The first issue relates to the basic methodology of measuring the generation of new brain cells, i.e., proliferation, as compared to survival of the newly made cells. Mostly, measures of neurogenesis reported are a combination of proliferation and survival, making it impossible to distinguish between these separate processes. The second aspect is in regards to the role of environmental factors which can affect both proliferation and survival independently. Especially the interaction between stress and learning is of importance since these might counteract each other in some circumstances. Reviewing the literature while taking these issues into account indicates that, in contrast to some findings, cell proliferation in the dentate gyrus of the hippocampus as a result of learning cannot be ruled out yet. On the other hand, increased survival of granule cells in the dentate gyrus as a result of hippocampal-dependent learning has been clearly demonstrated. Moreover, this learning-induced survival of granule cells, which were born before the actual learning experience, might provide a molecular mechanism for the 'use it or lose it' principle.     

Learning: Association or Computation? Introduction to a Special Section

The fundamental nature of learning is a central problem in psychology. Traditionally, psychologists have assumed that learning must involve the formation of associations. Early last century, the pioneering work of Pavlov on conditioned learning in animals seemed to put this assumption beyond doubt. More recently, many psychologists came to believe that a different kind of process must underlie complex learning, such as language learning in humans, and that this process must be described as computational rather than associative. Whether complex human learning is associative or computational continues to be a subject of intense research. The articles in this Special Section turn this debate on its head by asking whether simple animal learning is associative or computational. Surprisingly, the question is still very much open, and excitingly, it appears quite tractable.     

Teasing: for superiority or solidarity?

Humor among friends is typically regarded as a means of strengthening friendships. However, there may be a side of humor that is used to compete rather than bond (R. D. Alexander, 1986; C. R. Gruner, 1997). In the present studies, the participants were asked to imagine that they were sitting with a group of mixed-sex peers. One of the group (a same-sex friend) made a comment about the participant. Different groups of participants were told that the remark did or did not involve teasing. While the participants imagined they were the target of the remark, they rated their emotional reactions as well as their perceived relationship with the teaser and the character traits attributed to the teaser. The outcomes from analyses of variance of perceived competitiveness, emotional responses, and expected social outcomes largely supported superiority perspectives of humor.     

Augustine or Philistine? College Students' Sanctification of Learning and Its Implications

Sanctification is a psychological process in which aspects of life are associated with God (theistic sanctification) or sacred qualities (nontheistic sanctification). Sanctification accounts for outcomes in diverse areas, such as family, the environment, and work. One area yet to be examined is the sanctification of learning, which was addressed in the present study in a sample of 349 college students in the United States. Sanctification of education was related to better educational outcomes (i.e., positive emotions toward education, higher grade point averages, and psychological growth), partially through the mediator of good study strategies (critical thinking and self-regulation), as indicated by structural equation modeling. Hierarchical regressions revealed that sanctification of learning predicted higher levels of investment in learning, advanced study strategies, and better educational outcomes, over and above demographic and general religious variables. The present study demonstrates the beneficial implications of sanctifying learning while contributing to the growing body of literature that demonstrates the importance of the sanctification construct.     

Can Politics Practice Compassion?

On realist terms, politics is about power, security, and order, and the question of whether politics can practice compassion is irrelevant. The author argues that a politics of compassion is possible and necessary in order to address human security needs. She extend debates on care ethics to develop a politics of compassion, using the example of asylum seekers to demonstrate that politics can practice compassion with (1) attentiveness to the needs of vulnerable people who are suffering, (2) an active listening to the voices of the vulnerable, and (3) open, compassionate, and appropriate responses to particular needs.     

Learning To Parse?

A strong claim about human sentence comprehension is that the processing mechanism is fully innate and applies differently to different languages only to the extent that their grammars differ. If so, there is hope for an explanatory project which attributes all parsing strategies to fundamental design characteristics of the parsing device. However, the whole explanatory program is in peril because of the discovery (Cuetos & Mitchell, 1988) that Late Closure is not universal: Spanish, and also Dutch and other languages, favor Early Closure (high attachment) where English favors Late Closure flow attachment). I argue that the universal parser can weather this storm. Exceptions to Late Closure in Spanish and other languages are observed only in one construction (a relative clause attaching into a complex noun phrase [NP]), which is borderline in English too. For other constructions, low attachment is preferred in all languages tested. I propose that what differentiates the complex NP construction is the heaviness of the attachee compared to that of the host configuration. A relative clause is a heavy attachee, and the lower NP alone is small as a host; the relative is therefore better balanced if the whole complex NP is its host. A wide range of facts is accounted for by the principle that a constituent likes to have a sister of its own size. Light constituents will tend to attach low, and heavy ones to attach high, since larger constituents are dominated by higher nodes. A preference for balanced weight is familiar from work on prosodic phrasing. I suggest, therefore, that prosodic processing occurs in parallel with syntactic processing (even in reading) and influences structural ambiguity resolution. Height of attachment ambiguities are resolved by the prosodically motivated same-size-sister constraint. The exceptional behavior of English may be due to its prosodic packaging of a relative pronoun with the adjacent noun, overriding the balance tendency. If this explanation is correct, it is possible that all cross-language variations in parsing preferences are due to cross-language variations in the prosodic component of the competence grammar.     

Doing Ethics or Changing for the Better?

In this paper, classical pragmatism is used as a method, not as a substantial ethical theory, to develop “moral pragmatics.” Moral pragmatics offers a constructive approach for making progress where traditional ethical theories converge, and it innovates ethical deliberation. Assuming widespread agreement that real moral problems need practical solutions, the paper addresses two related problems: the missing link between ethical theories and moral practice, and the question of who is in charge of finding such solutions. It argues that “conscience” can create a link between ethical knowledge and moral practice, and that this partly discharges “the ethicist” from the task of solving problems that are not really, or not only, hers. Two specific methodological innovations are suggested that go beyond admonitions to render ethics sensitive to context. Instead, a reevaluation of “casuistry” and a sensitivity for “finding the right words” give an idea of how to achieve this goal.
