Can I Make a Difference? Efficacy,Employment, and Disability

Political efficacy is a widely studied phenomenon and an important predictor of political participation, but little is known about the political efficacy of the millions of people with disabilities in the United States. This paper reports the results of a nationally representative telephone survey of 1,240 people—stratified to include 700 people with disabilities—following the November 1998 elections. Several measures of efficacy that help predict political activity were found to be significantly lower among people with disabilities than among otherwise similar people without disabilities. Although lower levels of internal efficacy and civic skills could largely be explained by educational and employment gaps, lower levels of other variables (external efficacy, perceived influence of people with disabilities, and perceived treatment of people with disabilities) remained after applying a wide range of controls, indicating that people with disabilities are less likely to see the political system as responsive to them. This perception is concentrated among non–employed people with disabilities. The lower efficacy levels linked to "disability gaps" in employment, income, education, and group attendance appear to account for as much as half of the disability political participation gap; hence, policies intended to increase employment and educational opportunities for people with disabilities have potentially important political effects.     

Factor Structure of the Beck Depression Inventory—II in a Medical Outpatient Sample

This study examined the factor structure of the Beck Depression Inventory—II (BDI-II) in a sample of 127 individuals referred by their primary care physicians. Using exploratory factor analysis with oblique rotation, a 2-factor model appeared to be the most parsimonious representation of the data. The rotated factors accounted for approximately 53% of the variance. Consistent with previous research, the first factor was interpreted as a somatic–affective dimension and the second factor reflected a cognitive dimension. The correlation between these 2 factors was .79. It appears possible to divide the BDI-II into subscales to facilitate interpretation in medical patients.     

A test of the optimal classifier’s independence assumption in perceptual categorization

Observers completed perceptual categorization tasks that included separate base-rate/payoff manipulations, corresponding simultaneous base-rate/payoff manipulations, and conflicting simultaneous base-rate/payoff manipulations. Performance (1) was closer to optimal for 2:1 than for 3:1 baserate/ payoff ratios and when base rates as opposed to payoffs were manipulated, and (2) was more in line with the predictions from the flat-maxima hypothesis than from the independence assumption of the optimal classifier in corresponding and conflicting simultaneous base-rate/payoff conditions. A hybrid model that instantiated simultaneously the flat-maxima and the competition between reward and accuracy maximization (COBRA) hypotheses was applied to the data. The hybrid model was superior to a model that incorporated the independence assumption, suggesting that violations of the independence assumption are to be expected and are well captured by the flat-maxima hypothesis without requiring any additional assumptions. The parameters indicated that observers’ reward-maximizing decision criterion rapidly approaches the optimal value and that more weight is placed on accuracy maximization in separate and corresponding simultaneous base-rate/payoff conditions than in conflicting simultaneous base-rate/payoff conditions.     

Identity Cues: Evidence From and for Intra‐Individual Perspectives on Positive and Negative Stereotyping1

Traditional stereotyping research has adopted an intergroup perspective: Comparisons are made between ways in which targets belonging to different social groups are stereotyped. We adopt an intra‐individual perspective and examine how a single target, belonging to multiple social groups, is stereotyped differently based on identity cues. Participants interacted with a partner (a research confederate) in a series of e‐mail exchanges. The partner used e‐mail addresses that subtly cued either the partner's gender identity, the partner's ethnic identity, or neither identity. This subtle identity cue led participants to stereotype their partners in very different ways, biasing recall in directions consistent with the positive and negative stereotypes associated with the different identities cued. Applications of the findings to the problems that stereotypes create are discussed.     

Making Change Visible: The Possibilities in Assessing Mental Health Counseling Outcomes

The product of mental health counseling, unlike that of most professions, remains invisible to most people, leaving counselors vulnerable in a competitive market. The author argues that clinicians should recognize the value of, understand, and begin using outcome measures in their work. Research focusing on critical problems in psychotherapy outcome instruments, advances that have been made to counter those problems, areas of consensus among outcome researchers, and practical recommendations for using outcome measures are examined.     

On the Very Idea of Continental (or for that Matter Anglo–American) Philosophy

For most of the past century, philosophers on the Continent and those in the United States and Britain have taken themselves to be working in very different, even mutually exclusive, philosophical traditions. Although that may have been true until recently, it is no longer so. This piece surveys ten different proposed distinctions that have been offered between the two traditions, and it shows that none of them works, as there are major thinkers on both sides of each proposed distinction that do not neatly fit the proposal. The upshot of this is that it no longer makes sense to uphold the idea of two traditions, and that it is time we all dropped the mutual suspicion and denigration that have characterized relationships between us for the past hundred years.     

The Problem with Reid's Direct Realism

There is a problem about the compatibility of Reid's commitment to both a sign theory of sensations and also direct realism. I show that Reid is committed to three different senses of the claim that mind-independent bodies and their qualities are among the immediate objects of perception, and I then argue that Reid's sign theory conflicts with one of these. I conclude by advocating one proposal for reconciling Reid's claims, deferring a thorough development and defence of the proposal to another paper.     

The Moral Dilemmas Debate, Deontic Logic, and the Impotence of Argument

In this paper I argue for modesty concerning what theoretical reason can accomplish in the moral dilemmas debate. Specifically, I contend that philosophers' conclusions for or against moral dilemmas are driven less by rational argument and more by how the moral world intuitively appears to them.I support this thesis by first considering an argument against moral dilemmas, the argument from deontic logic, and showing that its persuasive force depends on one's having already accepted its conclusion. I then make a different, and general, case that any argument in the moral dilemmas debate concerning the defeasibility of conflicting obligations can be marginalized by making not-unreasonable adjustments in the conditions for wrongdoing.These two strands of argument are related by the notion of inescapable wrongdoing. It is our standing intuitions about inescapable wrongdoing which make the relevant deontic logical principles plausible or implausible to us. And whether wrongdoing can be inescapable is central to deciding what the conditions for wrongdoing are. My conclusion is that the arguments in the moral dilemmas debate merely implement whatever standing intuition we have concerning inescapable wrongdoing, and that apart from any such intuition the arguments are unpersuasive.     

Blocking in Rabbit Eyeblink Conditioning Is Not Due to Learned Inattention: Indirect Support for an Error Correction Mechanism of Blocking

Blocking is a classical conditioning task in which prior training to one cue such as a tone reduces learning about a second cue such as a light, when subsequently trained as a tone-light compound. Blocking has been theorized to come about through a US-modulated error correction mechanism by Rescorla & Wagner (1972) as well as through a mechanism of learned inattention as theorized by Mackintosh (1973). In the case of eyeblink conditioning, an error correction mechanism has been hypothesized to take place in the cerebellum while some form of inattention has been hypothesized to take place in the hippocampal region. The hypothesis we are testing is whether the mechanism of learned inattention is involved in blocking in rabbit eyeblink conditioning. If blocking in eyeblink conditioning is produced by a mechanism of learned inattention, then training to a previously blocked cue should be slower than training to that cue in a na?ve animal. Rabbits that had received tone training followed by tone-light training exhibited blocking. Rabbits that had been previously blocked to the light acquired conditioned responses to the light at the same rate as naive rabbits. This finding failed to support the hypothesis that blocking in rabbit eyeblink conditioning is due to learned inattention, but does support the Rescorla-Wagner mechanism of error correction. The present finding along with previous work on error correction mechanism in the cerebellar-brainstem circuit (Kim et al., 1998) lend support to the theory that blocking, at least in rabbit eyeblink conditioning, seems to be due to an error correction mechanism rather than a learned inattention mechanism.     

Primacy, recency, and suffix effects in auditory short-term memory for pure tones: evidence from a probe recognition paradigm.

The present study was designed to explore serial position and suffix effects in the short-term retention of nonverbal sounds. In contrast with previous studies of these effects, a probe recognition paradigm was used to minimize the possibility that participants would use a verbal labelling strategy. On each trial, participants heard a memory set consisting of three pure tones, followed five seconds later by a probe tone. Participants were required to indicate whether or not the probe tone had been a member of the memory set. On most trials, a suffix sound was presented 1 second following the third sound in the memory set. Results revealed that tones presented in the first and last positions of the memory set were recognized more accurately than were tones presented in the middle position. Furthermore, recognition of sounds presented in the last position was compromised when the memory set was followed by a postlist suffix of similar pitch, spectral composition, and spatial location.
