ELECTROPHYSIOLOGICAL CORRELATES OF STIMULUS EQUIVALENCE PROCESSES

Research reported here concerns neural processes relating to stimulus equivalence class formation. In Experiment 1, two types of word pairs were presented successively to normally capable adults. In one type, the words had related usage in English (e.g., uncle, aunt). In the other, the two words were not typically related in their usage (e.g., wrist, corn). For pairs of both types, event‐related cortical potentials were recorded during and immediately after the presentation of the second word. The obtained waveforms differentiated these two types of pairs. For the unrelated pairs, the waveforms were significantly more negative about 400 ms after the second word was presented, thus replicating the “N400” phenomenon of the cognitive neuroscience literature. In addition, there was a strong positive‐tending wave form difference post‐stimulus presentation (peaked at about 500 ms) that also differentiated the unrelated from related stimulus pairs. In Experiment 2, the procedures were extended to study arbitrary stimulus—stimulus relations established via matching‐to‐sample training. Participants were experimentally näive adults. Sample stimuli (Set A) were trigrams, and comparison stimuli (Sets B, C, D, E, and F) were nonrepresentative forms. Behavioral tests evaluated potentially emergent equivalence relations (i.e., BD, DF, CE, etc.). All participants exhibited classes consistent with the arbitrary matching training. They were also exposed also to an event‐related potential procedure like that used in Experiment 1. Some received the ERP procedure before equivalence tests and some after. Only those participants who received ERP procedures after equivalence tests exhibited robust N400 differentiation initially. The positivity observed in Experiment 1 was absent for all participants. These results support speculations that equivalence tests may provide contextual support for the formation of equivalence classes including those that emerge gradually during testing.     

Augustine,Arendt, and Anthropy

Arendt’s theoretical influence is generally traced to Heidegger and experientially to the traumatic events that occurred in Europe during the Second World War. Here, we suggest that Arendt’s conception of politics may be usefully enriched via a proto-anthropic principle found in Augustine and adopted by Arendt throughout her writings. By appealing to this anthropic principle; that without a spectator there could be no world; a profound connection is made between the ‘cosmic jackpot’ of life in the universe and the uniquely human activity that takes place in the political realm. By making this connection we suggest that solutions present themselves to a central puzzle arising in Arendt’s thought: namely, what it is that people actually do in the political realm. The first solution directly addresses the issue of content: what people talk about in Arendt’s public space. The second addresses the importance of ‘maintaining’ a space of appearances. The third considers the effect of participating in and observing the public domain. Consequently, we conclude that, for Arendt, action is nothing less than the activity of ‘world-making.’     

Substance Abuse Counselor Certification Requirements: Is It Time for a Change?

The minimum professional training requirements of 32 state certifying bodies for substance abuse counselors were analyzed. Only 14 of the certifying boards included any of the Council for the Accreditation of Counseling and Related Educational Programs core knowledge areas in their training components for Certified Addictions Counselors. Specific training in counseling and drug and alcohol treatment issues also appeared to be minimal. The lack of specific drug and alcohol training brings the quality of preparation for substance abuse counselors into question.     

Radical Orthodoxy, Luther, and the Challenge of Western Secularization

This "Theology Update" analyzes the Radical Orthodoxy of John Milbank in light of Martin Luther's dialectic between Law and Gospel. Milbank and his colleagues attack contemporary secularized culture in a manner parallel to Luther's attack on the 16^th century Holy Roman Empire for being soulless, aggressive, litigious, materialistic, and finally nihilistic. By re–engaging the battle between Thomas Aquinas and Duns Scotus, the radical orthodox party seeks to become post–modern by making a half turn back to the pre–modern Thomas, for whom philosophy and theology were integrated, subject was united to object, and being could be understood as relational because the Trinity is relational. Luther is mistakenly dismissed when reducing him to Scotus' nominalism, however. Lutheranism complements radical orthodoxy's analysis of secularized culture; yet Lutheranism maintains an integrity to faith–as the presence of Christ–that this new school fails to grant.     

Humeanism without Humean Supervenience: A Projectivist Account of Laws and Possibilities

Acceptance of Humean Supervenience and thereductive Humean analyses that entail it leadsto a litany of inadequately explained conflictswith our intuitions regarding laws andpossibilities. However, the non-reductiveHumeanism developed here, on which law claimsare understood as normative rather than factstating, can accommodate those intuitions. Rational constraints on such norms provide aset of consistency relations that ground asemantics formulated in terms offactual-normative worlds, solving theFrege-Geach problem of construing unassertedcontexts. This set of factual-normative worldsincludes exactly the intuitive sets ofnomologically possible worlds associated witheach possible set of laws. The extension ofthe semantics to counterfactual and subjunctiveconditionals is sketched. Potential objectionsinvolving subjectivity, mind-dependence, andnon-factuality are discussed.     

A Politically Liberal Conception of Civic Education

Liberal political theory is widely believed to be an inadequate source of civic commitment and thus of civic education primarily because of its commitment to what is perceived as a pervasive individualism. In this paper, I explore the possibility that John Rawls’s later political philosophy may provide a response to this belief. I first articulate a conception of liberal politics derived from Rawls’s idea of reflective equilibrium that generates an overlapping consensus about political principles among those who hold a wide variety of cultural and personal conceptions of the good. Next I develop the aims for civic education in a society that employs such a politics. Then I suggest the elements of the public school curriculum appropriate for such a civic education, including a robust multicultural education, intellectual reflection on the society’s history, and philosophical training that enables children to understand the events and policies of their nation as following from general political principles. I also consider the kinds of classroom practice that seem necessary to provide the motivation to engage in the process of the emergence of an overlapping consensus, including opportunities to develop and to reflect on the principles that may be included in the current consensus and to understand the way in which those principles relate to children’s developing conceptions of the good. Finally, I compare this conception of civic education to those of other liberal theorists.

Duration of auditory sensory memory in parents of children with SLI: a mismatch negativity study

In a previous behavioral study, we showed that parents of children with SLI had a subclinical deficit in phonological short-term memory. Here, we tested the hypothesis that they also have a deficit in nonverbal auditory sensory memory. We measured auditory sensory memory using a paradigm involving an electrophysiological component called the mismatch negativity (MMN). The MMN is a measure of the brain's ability to detect a difference between a frequent standard stimulus (1000 Hz tone) and a rare deviant one (1200 Hz tone). Memory effects were assessed by varying the inter-stimulus interval (ISI) between the standard and deviant. We predicted that parents of children with SLI would have a smaller MMN than parents of typically developing children at a long ISI (3000 ms), but not at a short one (800 ms). This was broadly confirmed. However, individual differences in MMN amplitude did not correlate with measures of phonological short-term memory. Attenuation of MMN amplitude at the longer ISI thus did not provide unambiguous support for the hypothesis of a reduced auditory sensory memory in parents of affected children. We conclude by reviewing possible explanations for the observed group effects.     

What Makes A Hero? The Impact of Integrity on Admiration and Interpersonal Judgment

Principled and expedient ideologies affect self-regulation and guide people along divergent ethical paths. A more principled ideology, indicative of higher claimed integrity, involves a greater personal commitment to ethical beliefs, standards, and self-schemas that facilitate positive social activities and help resist the temptation of illicit activities. Two studies showed that differences in reported integrity are related to people's preferences for and judgments of others. Those higher in integrity spontaneously described their heroes as more principled, honest, spiritual, and benevolently oriented toward others (Study 1). In addition, integrity was related to people's evaluations of characters who made ethical or unethical career decisions (Study 2). The judgments of those higher in integrity were greatly influenced by whether or not the decision was ethical but were largely unaffected by the consequences (career success or failure), whereas those lower in integrity were less influenced by whether the decision was ethical and more influenced by the career consequences.
