BEWILDERMENT AND THEREAFTER: Some Reflections in Response to Lee Yearley

The following reflections were originally an oral response to issues raised in Lee Yearley's presentation in May 2009 at Harvard Divinity School. As written here, they follow upon his oral and now written comments, highlighting key issues and points for development, drawing on this respondent's expertise in comparative and Hindu studies.     

Serial pattern learning by event observation.

Serial pattern learning was investigated in a variation of the task introduced by Nissen and Bullemer (1987). We presented an asterisk at 1 of 4 spatial locations on each trial, and Ss either responded with a keypress or observed the event. The first 4 blocks contained 10 repetitions of a 10- or 16-element pattern, and the 5th block contained a random sequence. The difference in response time on the 5th random block and the previous patterned block served as an indirect measure of pattern learning. A direct measure was obtained in a final test block in which Ss predicted the next asterisk position. Equivalent learning occurred for responding and observing with indirect measures, but observation was superior with direct measures. These findings indicate that knowledge of serial order can develop through simple perceptual experience, and this is more available to deliberate recall than is knowledge acquired while responding.     

Sex-role change, anomie and female suicide: a test of alternative Durkheimian explanations.

Durkheim's influential book, Suicide, provides general (economic) anomie, conjugal anomie, and sex-role convergence explanations of changes in suicide rates under conditions of social change. We used trend analyses of American suicide rates and female/male suicide ratios from 1950 to 1984 and the regression of the ratios on female educational attainment, white female labor force participation, white fertility rates, and divorce rates to examine these explanations. The general anomie explanation of female suicide trends is supported for the middle-aged (30 to 54 years) but not for the young (10 to 30 years) or the elderly (55 to 74 years). The conjugal anomie proposition is at best supported for age groups between 15 and 44 when general anomie is not pronounced. The role convergence explanation is rejected for all 13 5-year-age-groups. General anomie may not be a viable explanation of suicide trends for groups actively supporting relevant social changes or not yet tradition-bound or for groups whose retirement status reduces the importance of some social changes.     

A cascade of rejection and appearance preoccupation: Adolescents’ body dysmorphic symptoms and appearance rejection sensitivity over 4 years

Adolescence is a high-risk period for body image disturbance and appearance concerns. In a cascade model, we examined interrelations of body dysmorphic symptoms (BDS) with appearance rejection sensitivity (ARS) and tested gender moderation. Participants were 397 Australian adolescents (T1 Mage = 11.7, SD = 0.91; 56% girls) who completed six surveys over 4 years. In a random-intercept cross-lag model, two (of five possible) paths showed ARS predicted higher subsequent BDS, and three (of five possible) paths showed BDS predicted higher subsequent ARS. Girls reported more BDS and ARS than boys, and random intercepts of BDS and ARS were correlated with the correlation stronger in girls than boys. Cross-lag BDD-ARS associations over the six waves were not significantly moderated by gender. Overall, girls are at higher risk of appearance concerns than boys, but BDD-ARS cascade effects do not differ between girls and boys.     

Articulatory and Phonological Determinants of Word Length Effects in Span Tasks

Several previous studies have shown that memory span is greater for short words than for long words. This effect is claimed to occur even when the short and long words are matched for the number of syllables and phonemes and so to provide evidence for subvocal articulation as being one mechanism that underlies memory span (Baddeley, Thomson, & Buchanan, 1975). The three experiments reported in this paper further investigate the articulatory determinants of word length effects on span tasks. Experiment 1 replicated Baddeley et al.'s finding of an effect of word length on auditory and visual span when the stimuli consist of words that differ in terms of the number of syllables. Experiments 2 and 3 showed that the effects of word length are eliminated when the words in the span task are matched for the number of syllables and phonemes but differ with respect to the duration and/or complexity of their articulatory gestures. These results indicate that it is the phonological structure of a word and not features of its actual articulation that determines the magnitude of the word length effect in span tasks.     

Hearing a Still-Ticking Bomb Argument: A Reply to Bufacchi and Arrigo

My aim in this paper is to demonstrate that the recent anti-Ticking Bomb argument offered by Bufacchi and Arrigo is unsuccessful. To adequately refute the Ticking Bomb strategy, I claim, requires carefully addressing both policy questions and questions involving exceptional conduct.
