Variability in the timing of responses during repetitive tapping with alternate hands

Summary This paper addresses the question of whether a simple two-stage account of variability in timing developed for single-hand repetitive tapping is applicable to regular tapping with the hands in alternation. The task required key presses at a steady rate, previously set by a periodic auditory signal. On separate blocks of trials four subjects used the index finger of the left hand or of the right hand at intervals of 200, 400, and 800 ms or alternated between the hands at intervals of 100, 200, or 400 ms. For each subject the variability of the between-hand intervals in the 200- and 400-ms alternate-hand conditions was greater than the variability of the same interval in the single-hand conditions. In the 100-ms alternate-hand condition correlations between adjacent (between-hand) intervals were reliably less then –.5. These results are inconsistent with the simple two-stage model, and two variants are shown to provide a better qualitative fit to at least some aspects of the data.     

From a linear to a contextual model of the ABCs of RET

The Contextual ABC Model follows from the recognition that the ABCs of RET ... are oversimplified and omit salient information about human disturbance and its treatment (Ellis, 1984). It is an attempt to capture the mutual and reciprocal intricacies of the ABC process, the complexities of human cognition, and the power of the person to create feelings and behaviors, thoughts and ideas, and even environmental events independent of any prior activating stimuli. It is believed that this model adds to the scope and power of RET's theory and practice without subtracting from or omitting what already exists.     

Different and similar at the same time: when the activation of dissimilarity makes people look more similar

Whether two people are presented as similar or different may have a strong impact on the outcome of their comparison. In the present research, we examined the counterintuitive hypothesis that activating dissimilarity increases the perception of similarities between people, in other words increases perceived feature overlap, during the comparison process. We investigated this prediction by asking people to judge the perceived similarity between two faces with a suboptimally related or unrelated morph inserted in between (to influence joint categorization), and with similar or different facial expressions (to vary the salience of similar or different features). The results confirmed our expectations: In the similarity (joint categorization) condition, two faces that differed in expression were perceived as more dissimilar than faces with the same expression. More important for our prediction, in the dissimilarity condition two faces with different expressions were no longer perceived as more dissimilar than two faces with the same expression. We discuss implications of these findings for the mechanisms underlying comparisons between people. Copyright © 2007 John Wiley & Sons, Ltd.     

Phenomenology and Theology: Situating Heidegger’s Philosophy of Religion

This essay considers the philosophical and theological significance of the phenomenological analysis of Christian faith offered by the early Heidegger. It shows, first, that Heidegger poses a radical and controversial challenge to philosophers by calling them to do without God in an unfettered pursuit of the question of being (through his ‘destruction of onto-theology’); and, second, that this exclusion nonetheless leaves room for a form of philosophical reflection upon the nature of faith and discourse concerning God, namely for a philosophy of religion in a phenomenological mode (as exemplified most clearly in Heidegger’s 1920/21 lectures on the phenomenology of religious life). However, it is argued that the theological roots of Heidegger’s own phenomenological analyses subvert his frequently asserted claim concerning the incompatibility of Christian faith and philosophical inquiry.     

Gender and ethnic differences in sexual attitudes at a Hispanic-serving university

The authors studied sexual attitudes in 328 university students from 10 undergraduate classes at a Hispanic-serving university near the Texas-Mexico border. Men (n = 128) and women (n = 199) rated their level of agreement with 38 items on a revised sexuality questionnaire. There were 283 self-identified Hispanic students and 44 self-identified non-Hispanic students in the sample. For the most part, these students agreed with one another, although there were statistically significant differences, with women being less permissive or more sex negative than men were on items relating to oral sex, premarital intercourse, love and sex, masturbation, Playboy magazine, and pornography. For the entire sample, 26 of the 38 items showed statistically significant gender differences. For Hispanics only, 23 of the 38 items showed statistically significant differences, with gender differences those of the sample as whole. There were 8 statistically significant differences between Hispanic and non-Hispanic students, with Hispanic students tending to be more conservative. The authors discuss findings that are contradictory to D. M. Buss's (1999, 2000) evolutionary psychology jealousy theory, namely that women in the present study were more jealous than men were on the sexual intercourse item.
