Tye’s Representationalism: Feeling the Heat?

According to Tyes PANIC theory of consciousness, perceptualstates of creatures which are related to a disjunction ofexternal contents will fail to represent sensorily, andthereby fail to be conscious states. In this paper I arguethat heat perception, a form of perception neglected in therecent literature, serves as a counterexample to Tyesradical externalist claim. Having laid out Tyes `absentqualia scenario, the PANIC theory from which it derivesand the case of heat perception as a counterexample, Idefend the putative counterexample against three possibleresponses: (1) that heat perception represents general(i.e. non-disjunctive) intrinsic properties of objects,(2) that heat perception represents the non-specific heatenergy that is transferred between a subjects body andanother body and (3) that heat perception exclusivelyrepresents heat properties of the subjects own body.     

Experimental tests of an attitudinal theory of the gender gap in voting

This research examined the hypothesis that gender gaps in voting stem from differences in the extent to which men and women agree with candidates' issue stances. Two initial experiments portraying candidates by their sex and attitudes and a third experiment that also included information about political party produced the predicted attitudinal gender-congeniality effect: Participants of each sex reported greater likelihood, compared with participants of the other sex, of voting for the candidate who endorsed positions typically favored more by their own sex than the other sex. In addition, this gender-congeniality effect was present among Republican and independent participants but absent among Democratic participants because Democratic men as well as women favored candidates who advocated the positions typically favored by women. Interpretation invoked the importance of group interest based on gender as an influence on women's voting.     

Perirhinal cortex lesions impair context aversion learning

Rats with perirhinal cortex lesions were compared with sham controls on a conditional discrimination in which saccharin was paired with LiCl in context 1, but paired with saline in context 2. Perirhinal-lesioned rats were slightly slower to acquire the discrimination but reached control levels by the end of acquisition. Both groups showed transfer to familiar tap water, consuming less in context 1 than in context 2. Unlike sham rats, perirhinal rats failed to show an aversion to context 1 on a place choice test. These data provide neuroanatomical support for the postulated difference between Pavlovian conditioning and conditional learning.     

Motion in depth: adequate and inadequate simulation

We measured errors in estimating the absolute time to collision with a simulated approaching textured object. The texture elements were circular bright dots. When we matched the rate of angular expansion of the simulated object, the rate of expansion of the texture dots, and the rate of increase of dot separation, so as to accurately simulate an approaching object, errors were small underestimations that were independent of dot size (mean of 3.2%). When dot angular size was held constant during the simulated approach, errors were the same as when the simulation was accurate, provided that dot size was less than 2.2-4.4 min of arc. As dot size was progressively increased, errors changed to overestimations. For the largest dot size used (10.5 min of arc at time t = 0), time to collision was overestimated by up to 21%. A sufficiently large overestimation would mean that measures taken to avoid collision would be too late. We suggest that the relevance to everyday life of data on the perception of motion in depth and self-motion collected using constant-sized dot displays might be questionable if dot size exceeds 2.2-4.4 min of arc.     

Adults’ perception of native and nonnative vowels: Implications for the perceptual magnet effect

Two experiments were conducted to evaluate the perceptual magnet effect. In Experiment 1, Amer-ican English speakers representing diverse dialects were presented with a fine-grained set of stimuli (varying in just noticeable differences forF1 andF2) and indicated whether they heard “/i/” or “not /i/,” thus delimiting the /i/ portion of the vowel space for individual subjects. Then these same subjects selected their own /i/ prototype with a method-of-adjustment procedure. The data from this experiment were used to synthesize customized prototype and nonprototype stimulus sets for Experiment 2. In Experiment 2,24 of our original 37 subjects completed a discrimination task for each of three conditions, in which vector stimuli varied from the subject’s prototype, the nonprototype, or a foreign vowel (/y/) in 15-mel steps. Subjects displayed higher discrimination, as indexed byd′, for the nonprototype condition than they did for both the prototype and the foreign conditions. In addition, discrimination was better for variants further away from the referent in each condition. However, discrimination was not especially poor for stimuli close to subjects’ individual prototypes—a result that would have yielded the strongest support for the operation of a magnet effect. This negative finding, together with other aspects of our results, raises problems for any theory of vowel perception that relies solely on “one-size-fits-all” prototype representations.     

Potential Bone-Marrow Donors and Their Spouses: The Effects of Volunteerism on Distress Levels1

The current study sought to provide a better understanding of the reactions of bone-marrow volunteers to the possibility of donating by examining these volunteers in the context of their closest relationships. Using Tesser's (1988) self-evaluation maintenance (SEM) model as a guide, we examined the influence of spouses who are also volunteers on each member of the couple's distress levels and on the marrow volunteer's ambivalence about donating. We also examined the independent effects of known risk factors for donation-related distress and the combined effects of spouse volunteer status and these risk factors on distress levels. Questionnaire data were collected from 278 couples selected from 39 bone-marrow donor centers. Results demonstrated that when spouses of potential donors were engaged in any type of volunteer activity, members of the couple felt greater anxiety than when spouses were not volunteers. Additionally, other variables were found to have a conjoint effect with spouse volunteer status on volunteer and spouse anxiety levels.     

Psychological Safety and Appreciation of Differences in Counselor Training Programs: Examining Religion,Spirituality, and Political Beliefs

This study focused on the extent to which religion, spirituality, and political beliefs predicted counseling students' perceptions of psychological safety and appreciation of differences in their programs. The authors used hierarchical regression models to analyze data from 264 students from 4 different institutions. Results indicated that student age, political conservatism, extrinsic religiosity, and intrinsic spirituality were significant predictors of perceived psychological safety and appreciation of differences. The authors discuss implications of these findings.     

A Discriminant Analysis of Gender and Counselor Professional Identity Development

This quantitative study examined professional identity development and orientation for 489 counseling practitioners, educators, and trainees as predicted by participant‐identified sex and engagement in professional activities. Differences between male and female participants regarding aspects of professional identity were evaluated. Discriminant analysis results indicate sex differences in professional identity development. Additional regression analysis revealed a significant predictive relationship between professional engagement and professional identity orientation and development.     

Lost in translation? Psychometric properties and construct validity of the English Essen Climate Evaluation Schema (EssenCES) social climate questionnaire

The social climate of correctional (forensic) settings is likely to have a significant impact on the outcome of treatment and the overall functioning of these units. The Essen Climate Evaluation Schema (EssenCES) provides an objective way of measuring social climate that overcomes the content, length, and psychometric limitations of other measures. But the English translation of the EssenCES has yet to be sufficiently validated for use in forensic settings in the United Kingdom. The current study presents psychometric properties (factor structure and internal consistency) and an examination of construct validity with the English EssenCES. Satisfactory internal consistency was found for all EssenCES scales, and the expected three-factor structure was confirmed with both staff and residents and in prison and secure hospital settings using confirmatory factor analysis. Evidence to support construct validity was established using multilevel models, which showed statistically significant associations between scores on the EssenCES and scores on the Working Environment Scale, institutional aggression, and site security. Future validation work and potential practical applications of the EssenCES are discussed.
