Long-term impact of parental divorce on optimism and trust: changes in general assumptions or narrow beliefs?

Two studies were conducted to examine the long-term impact of parental divorce on beliefs about the self and others. In Study 1, college-aged children of divorce and students from intact families did not differ on 8 basic assumptions or on measures of depression. Those whose parents are divorced, however, were less optimistic about the success of their own future marriages. Assumptions about the benevolence of people best predicted the marital optimism of the parental divorce group, but not of the intact family group. In Study 2, assumptions about the benevolence of people were explored in terms of trust beliefs. College-aged children of divorce and a matched sample from intact homes differed only on marriage-related beliefs, not on generalized trust. Children of divorced reported less trust of a future spouse and were less optimistic about marriage. Exploratory analyses found that continuous conflict in family of origin adversely affected all levels of trust.     

It's a Museum,But Not as We Know It: Issues for Local Residents Accessing the Museum of Old and New Art

The Museum of Old and New Art (MONA), in Australia's island state of Tasmania, bears all the hallmarks of the new museology and a flagship museum. Located in a largely working class area, there are expectations of visitors from diverse socioeconomic backgrounds, particularly local residents. However most visitors are tourists, middle-class, and highly educated. In this article, the authors ask, “What are the issues affecting accessibility to MONA for local residents?” In asking this, they aim to better understand local engagement with MONA and shed light on potential socio-cultural transformation. Using a survey, interviews, and focus groups with local residents, the authors found that accessibility at MONA is defined along familiar socioeconomic lines, though there are indications of change that warrant further investigation. The expense of food and beverage, concern about children's behavior, and the explicit nature of some art all impact on accessibility, particularly for those with less cultural capital.     

Bratman on identity over time and identification at a time

According to reductionists about agency, an agent’s bringing something about is reducible to states and events (such as desires and beliefs) involving the agent bringing something about. Many have worried that reductionism cannot accommodate robust forms of agency, such as self-determination. One common reductionist answer to this worry (which I call “identification reductionism”) contends that self-determining agents are identified with certain states and events, and so these states and events causing a decision counts as the agent’s self-determining the decision. In this paper, I discuss Michael Bratman’s well-known identification reductionist theory and his general strategy of grounding an agent’s identification at a time in the agent’s identity over time. I develop two constraints that an adequate identification reductionist theory must satisfy, argue that Bratman’s theory cannot satisfy both, and show that his general strategy for grounding an agent’s identification at a time in the agent’s identity over time is without merit.     

Motivation and the Heart in the Xing Zi Ming Chu

In both content and historical position, the “Xing Zi Ming Chu” is of obvious significance for understanding the development of classical Chinese philosophy, particularly Confucian moral psychology. This article aims to clarify one aspect of the text, namely, its account of human motivation. This account can be divided into two parts. The first describes human motivation primarily in passive terms of response to external forces, as emotions arise from our nature when stimulated by things in the world. The second comes from the role of the heart, which takes a more active role in shaping our responses to the world. This article focuses on the role of the heart. At stake is the status of human agency, in particular, the degree to which the heart, through the formation of a stable intention, allows us to go beyond being simply pulled along by external forces.     

Sparse distributed memory for ‘conscious’ software agents

In this work we are reporting a case study on the use of SDM as the associative memory for a software agent, CMattie, whose architecture is modeled on human cognition. Sparse distributed memory (SDM) is a content-addressable memory technique that relies on close memory items tending to be clustered together. In this work, we used an enhanced version of SDM augmented with the use of genetic algorithms as an associative memory in our ‘conscious’ software agent, CMattie, who is responsible for emailing seminar announcements in an academic department. Interacting with seminar organizers via email in natural language, CMattie can replace the secretary who normally handles such announcements. SDM is a key ingredient in a complex agent architecture that implements global workspace theory, a psychological theory of consciousness and cognition. In this architecture, SDM, as the primary memory for the agent, provides associations with incoming percepts. These include disambiguation of the percept by removing noise, correcting misspellings, and adding missing pieces of information. It also retrieves behaviors and emotions associated with the percept. These associations are based on previous similar percepts, and their consequences, that have been recorded earlier. SDM also possesses several key psychological features. Some enhancements to SDM including multiple writes of important items, use of error detection and correction, and the use of hashing to map the original information into fixed size keys were used. Test results indicate that SDM can be used successfully as an associative memory in such complex agent architectures. The results show that SDM is capable of recovering a percept based on a part of that percept, and finding defaults for empty perception registers. The evaluation of suggested actions and emotional states is satisfactory. We think that this work opens the door to more scientific and empirical uses for SDM.     

A software agent model of consciousness.

Baars (1988, 1997) has proposed a psychological theory of consciousness, called global workspace theory. The present study describes a software agent implementation of that theory, called "Conscious" Mattie (CMattie). CMattie operates in a clerical domain from within a UNIX operating system, sending messages and interpreting messages in natural language that organize seminars at a university. CMattie fleshes out global workspace theory with a detailed computational model that integrates contemporary architectures in cognitive science and artificial intelligence. Baars (1997) lists the psychological "facts that any complete theory of consciousness must explain" in his appendix to In the Theater of Consciousness; global workspace theory was designed to explain these "facts." The present article discusses how the design of CMattie accounts for these facts and thereby the extent to which it implements global workspace theory.     

Explaining the discrepancy between intentions and actions: the case of hypothetical bias in contingent valuation

An experiment was designed to account for intention-behavior discrepancies by applying the theory of planned behavior to contingent valuation. College students (N = 160) voted in hypothetical and real payment referenda to contribute $8 to a scholarship fund. Overestimates of willingness to pay in the hypothetical referendum could not be attributed to moderately favorable latent dispositions. Instead, this hypothetical bias was explained by activation of more favorable beliefs and attitudes in the context of a hypothetical rather than a real referendum. A corrective entreaty was found to eliminate this bias by bringing beliefs, attitudes, and intentions in line with those in the real payment situation. As a result, the theory of planned behavior produced more accurate prediction of real payment when participants were exposed to the corrective entreaty.     

Sham surgery: An ethical analysis

Surgical clinical trials have seldom used a "sham" or placebo surgical procedure as a control, owing to ethical concerns. Recently, several ethical commentators have argued that sham surgery is either inherently or presumptively unethical. In this article I contend that these arguments are mistaken, and that there are no sound ethical reasons for an absolute prohibition of sham surgery in clinical trials. Reflecting on three cases of sham surgery, especially on the recently reported results of a sham-controlled trial of arthroscopic surgery for arthritis of the knee, I present an ethical analysis that focuses on the methodological rationale for use of sham surgery, risk-benefit assessment, and informed consent.
