Psychopathy: what apology making tells us about moral agency

Psychopathy is often used to settle disputes about the nature of moral judgment. The “trolley problem” is a familiar scenario in which psychopathy is used as a test case. Where a convergence in response to the trolley problem is registered between psychopathic subjects and non-psychopathic (normal) subjects, it is assumed that this convergence indicates that the capacity for making moral judgments is unimpaired in psychopathy. This, in turn, is taken to have implications for the dispute between motivation internalists and motivation externalists, for instance. In what follows, we want to do two things: firstly, we set out to question the assumption that convergence is informative of the capacity for moral judgment in psychopathy. Next, we consider a distinct feature of psychopathy which we think provides strong grounds for holding that the capacity for moral judgment is seriously impaired in psychopathic subjects. The feature in question is the psychopathic subject’s inability to make sincere apologies. Our central claim will be this: convergence in response to trolley problems does not tell us very much about the psychopathic subject’s capacity to make moral judgments, but his inability to make sincere apologies does provide us with strong grounds for holding that this capacity is seriously impaired in psychopathy.     

Acquiring new word meaning: What does it tell us about development

R. J. Sternberg (1984, Developmental Review, 4, 113–138) offers a thoughtful and provocative essay on how individuals acquire meanings for novel or unfamiliar nouns. The Sternberg essay, however, is incomplete on a number of grounds. By stressing general processes and specific knowledge as critical components in the acquisition of verbal concepts, for example, it overlooks two logically complementary categories—specific processes and general knowledge—and the role these play in the acquisitions in question. A second concern is that the paper blurs distinctions among development, short-term learning, and the origin/acquisition of individual differences. Finally, Sternberg is encouraged to frame the specific phenomenon described here within the context of a larger theory of intellectual development and to indicate what else this specific model can be used to explain.     

Demonstrations of spatiotemporal integration and what they tell us about the visual system

Five sets of displays are presented on the journal website to be viewed in conjunction with the text. We concentrate on the factors that give rise to the integration and disruption of the direction of apparent motion in two-dimensional and three-dimensional space. In the first set of displays we examine what factors contribute to the integration and disruption of apparent motion in the Ramachandran/Anstis clustered bistable quartets. In the second set we examine what factors give rise to the perception of the direction of motion in rotating two-dimensional wheels and dots. In the third and fourth sets we examine how the depth cues of shading and disparity contribute to the perception of apparent motion of opaque displays, and to the perception of rotating unoccluded displays, respectively. In the fifth set we examine how the depth cue of motion parallax influences the perception of apparent motion. Throughout, we make inferences about the roles which various parallel pathways and cortical areas play in the perceptions produced by the displays shown.

The confusion about epistemology and "epistemology"--and what to do about it

The epistemology debates within the field of family therapy have become relatively infrequent in the last year or so, perhaps as a consequence of the confusion they have generated for many family therapists. This article maintains that the primary reason for the confusion is a failure to distinguish clearly between the conventional meaning of the term epistemology, which concerns the nature of knowledge, and the unconventional meaning given the term in family therapy, which concerns the nature of what we know. It is proposed that the confusion can be diminished by understanding the relationship between the two meanings, which are here distinguished as epistemology (meaning 1) and epistemology (meaning 2) respectively. Particular attention is given to the logical consequences of adopting a position on epistemology (meaning 1)—e.g, is the knower capable of knowing an independent reality, or does the act of knowing make its own reality?—or on epistemology (meaning 2)—e.g., is causality linear or nonlinear?. The relevance and implications of these problems for the theory and practice of family therapy are discussed.     

Animats and what they can tell us

Animats-autonomous robots or simulations of animals-and the animat approach represent the most recent attempt to comprehend the capacity of animals for autonomous generation of adaptive, intelligent behavior in complex, changing environments. Motivated by perceived limitations in classical artificial intelligence (AI), the animat approach promulgates an alternative, bottom-up route to understanding intelligent behavior. Important tenets include: (1) that adaptive behavior is best understood by focusing on the interaction between a behaving individual and its environment, hence the interest in `embodied' physical robots `situated' in natural environments; (2) that specific abilities, `behaviors', are more natural units of analysis and design than general, information-processing functions and world models; and (3) that high-level behaviors will emerge as systems composed of simple behavioral competences become more complex. Thus, animat research often begins with low-level sensorimotor abilities and then moves up towards higher, cognitive functions. Both in analysis and in design, the animat approach borrows heavily from ethology, psychology, neurobiology and evolutionary biology, as well as from connectionism. For AI and robotics researchers, understanding the mechanisms behind adaptive behavior is secondary to creating them, but natural scientists can hope for tools and concepts to aid understanding of biological systems.     

Direct instruction: What it is and what it is becoming

This essay describes the principles of Direct Instruction design and delivery used to establish clear, unambiguous communication and maximize student responding. Direct Instruction research findings are summarized: achievement of low-income students in Follow Through, longitudinal results, and the effectiveness of Direct Instruction for students with handicaps. Finally, new directions for Direct Instruction, technological applications and instruction of higher-order skills, are discussed.     

Knowing what you're feeling and knowing what to do about it: Mapping the relation between emotion differentiation and emotion regulation

Individuals differ considerably in their emotion experience. Some experience emotions in a highly differentiated manner, clearly distinguishing among a variety of negative and positive discrete emotions. Others experience emotions in a relatively undifferentiated manner, treating a range of like-valence terms as interchangeable. Drawing on self-regulation theory, we hypothesised that individuals with highly differentiated emotion experience should be better able to regulate emotions than individuals with poorly differentiated emotion experience. In particular, we hypothesised that emotion differentiation and emotion regulation would be positively related in the context of intense negative emotions, where the press for emotion regulation is generally greatest. To test this hypothesis, participants' negative and positive emotion differentiation was assessed using a 14-day diary protocol. Participants' regulation of negative and positive emotions was assessed using laboratory measures. As predicted, negative emotion differentiation was positively related to the frequency of negative emotion regulation, particularly at higher levels of emotional intensity.     

Essentialist beliefs about homosexuality: structure and implications for prejudice

The structure of beliefs about the nature of homosexuality, and their association with antigay attitudes, were examined in three studies (Ns = 309, 487, and 216). Contrary to previous research, three dimensions were obtained: the belief that homosexuality is biologically based, immutable, and fixed early in life; the belief that it is cross-culturally and historically universal; and the belief that it constitutes a discrete, entitative type with defining features. Study 1 supported a three-factor structure for essentialist beliefs about male homosexuality. Study 2 replicated this structure with confirmatory factor analysis, extended it to beliefs about lesbianism, showed that all three dimensions predicted antigay attitudes, and demonstrated that essentialist beliefs mediate associations between prejudice and gender, ethnicity, and religiosity. Study 3 replicated the belief structure and mediation effects in a community sample and showed that essentialist beliefs predict antigay prejudice independently of right-wing authoritarianism, social dominance orientation, and political conservatism.     

The absent professor: why we don't teach research ethics and what to do about it

Research ethics education in the biosciences has not historically been a priority for research universities despite the fact that funding agencies, government regulators, and the parties involved in the research enterprise agree that it ought to be. The confluence of a number of factors, including scrutiny and regulation due to increased public awareness of the impact of basic research on society, increased public and private funding, increased diversity and collaboration among researchers, the impressive success and speed of research advances, and high-profile cases of misconduct, have made it necessary to reexamine how the bioscience research community at all levels provides ethics education to its own. We discuss the need to and reasons for making ethics integral to the education of bioscientists, approaches to achieving this goal, challenges this goal presents, and responses to those challenges.     

Disability and participation: It's about us but still without us!

Participation is often espoused as a strategy to promote inclusion, social justice and equality. Exactly how to facilitate participation in practice is often not explicated, nor are the challenges or issues highlighted. By drawing on interview data, the first aim of this paper is to identify the key barriers to participation in an organizational planning activity as experienced by 12 disabled and non‐disabled staff and board members in a small community‐based disability advocacy organization. The second aim is to draw upon Jim Ife's principles of participation to further analyse the factors that hinder and enable participation in organizations. Reported barriers to participation were categorized at individual, interpersonal and organizational levels of analysis, and included a lack of skills and competence, interpersonal conflicts, poor resourcing and ad hoc processes. The importance of understanding the dynamic interplay of individual and structural factors, valuing different forms of participation and having participatory structures and processes embedded in organizational settings are all highlighted. This study illustrates that, even in an organization that is specifically attuned to meeting the needs of disabled people, there is still considerable exclusion and institutional discrimination. Strategies to promote participation within an organizational context may include providing sufficient time for reflection and support, and opportunities for board members to learn how to take part in constructive planning activities and to develop their strengths.
