Attentional disregulation: a benefit for implicit memory

The authors investigated the effect of age and time of testing on the ability to control attention and addressed the possibility that older adults' susceptibility to distraction may sometimes facilitate performance on a later cognitive task. Using a modification of a G. Rees, C. Russell, C. D. Frith, and J. Driver (1999) procedure, the authors asked the participants to make same or different judgments on line drawings superimposed with task-irrelevant letter strings. Memory for the distractors was subsequently tested with an implicit memory task. Both older and young adults demonstrated greater memory for distractors at nonoptimal times of day than at optimal times of day; however, older adults showed considerably better memory for the distractors than did young adults.     

View-specific coding of face shape

Monkey and human cortex contain view-specific face neurons, but it remains unclear whether they code face shape. We tested the view specificity of face-shape coding by inducing figural face aftereffects at one viewpoint (3/4 left) and testing generalization to different viewpoints (front view and 3/4 right). The aftereffects were induced by adaptation to consistent figural distortions (contracted or expanded), which shifts the distortion perceived as most normal toward the adapting distortion. The strong aftereffect that was observed at the adapting view was significantly and substantially reduced for both front-view test faces and mirror-image (3/4 right) test faces, indicating view specificity. The limited transfer across mirror views is strong evidence of view specificity, given their figural similarity. The aftereffects survived a size change between adaptation and test faces (Experiment 2), a result that rules out low-level adaptation as an explanation. These results provide strong evidence that face-shape coding is view-specific.     

Stem cell research in a Catholic institution: yes or no?

Catholic teaching has no moral difficulties with research on stem cells derived from adult stem cells or fetal cord blood. The ethical problem comes with embryonic stem cells since their genesis involves the destruction of a human embryo. However, there seems to be significant promise of health benefits from such research. Although Catholic teaching does not permit any destruction of human embryos, the question remains whether researchers in a Catholic institution, or any researchers opposed to destruction of human embryos, could participate in research on cultured embryonic stem cells, or whether a Catholic institution could use any therapy that ultimately results from such research. This position paper examines how such research could be conducted legitimately in a Catholic institution by using an ethical analysis involving a narrative context, the nature of the moral act, and the principle of material cooperation, along with references to significant ethical assessments. It also offers tentative guidelines that could be used by a Catholic institution in implementing such research.     

Convergent validity of the Agnew Relationship Measure and the Working Alliance Inventory

The convergent validity of the Agnew Relationship Measure (ARM) and the Working Alliance Inventory (WAI) was assessed in samples drawn from 2 comparative clinical trials of time-limited psychotherapies for depression. In 1 sample, clients (n = 18) and therapists (n = 4) completed self-report versions of both measures after every session (n = 198). In the other sample, clients (n = 39) and therapists (n = 6) completed the ARM, and observers subsequently rated selected audiotaped sessions (n = 78) using the WAI. In both samples, the ARM's core alliance scales (Bond, Partnership, and Confidence) were correlated with the WAI's scales (Bond, Tasks, and Goals) strongly when assessed within client and therapist perspectives and, with some qualifications, moderately when assessed between client, therapist, and observer perspectives, supporting the assumption that the ARM and the WAI measure some of the same core constructs.     

Fitting the mind to the world: face adaptation and attractiveness aftereffects

Average faces are attractive, but what is average depends on experience. We examined the effect of brief exposure to consistent facial distortions on what looks normal (average) and what looks attractive. Adaptation to a consistent distortion shifted what looked most normal, and what looked most attractive, toward that distortion. These normality and attractiveness aftereffects occurred when the adapting and test faces differed in orientation by 90° (+45° vs. −45°), suggesting adaptation of high-level neurons whose coding is not strictly retino- topic. Our results suggest that perceptual adaptation can rapidly recalibrate people's preferences to fit the faces they see. The results also suggest that average faces are attractive because of their central location in a distribution of faces (i.e., prototypicality), rather than because of any intrinsic appeal of particular physical characteristics. Recalibration of preferences may have important consequences, given the powerful effects of perceived attractiveness on person perception, mate choice, social interactions, and social outcomes for individuals.     

Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.     

Factors affecting the success of referential communication

A study was designed to determine the factors that cause difficulty to adolescent listeners performing referential communication. Difficulties might arise because of (a) inability to detect message inadequacy, (b) misperception of task demands, or (c) inability to formulate an adequate question. The results of the present study showed that both able and less able subjects were able to detect message inadequacy almost perfectly, but that less able subjects had severe difficulty in formulating adequate requests for more information. Analysis suggests that in our 13-to 14-year-old subjects information-processing limitations, rather than lack of purely linguistic skills, account for most of the error variance when the task demands are transparent.This research was supported by a grant from the Leverhulme Foundation (U.K.) to the third author, and a grant from the Economic and Social Research Council (U.K.) to the first author (reference CO8250011).

How Should We Discharge Our Responsibilities to Eradicate Poverty?

In this article I present four central challenges for Hennie Lötter’s book Poverty, Ethics and Justice. The first criticism takes issue with Lötter’s focus on social rather than global justice. Though he seems to be concerned with poverty everywhere, he takes social rather than global justice as the primary unit of analysis and this leads to a certain blindness to the ways in which discharging duties to the poor is a global not just society or state level project. My alternative perspective also gives us more insights into the nature of our duties to one another and can accommodate a wider range of duties. A second set of concerns revolves around what we must do to discharge our duties to the poor and what we need to know to help effectively. We come to appreciate that helping effectively is no easy matter and supplying more guidance would be helpful. Third, after discussing some relevant empirical research, I also discuss the kinds of initiatives that deserve support, that can act as rough guidelines for would-be assisters. These more simplified guidelines do not place such heavy epistemic demands on those aiming to help. Fourth, I explore whether we can offer some more guidelines for determining which of many plausible policy initiatives we should support, given that there are many good ideas and limited resources. I offer one guideline for choosing among what appear to be plausible policies to support.     

Hemisphere differences in an auditory Stroop test

In an auditory Stroop test, right-handed subjects were required to judge the pitch of the following stimuli: two pure tones, one at a high frequency and one at a low frequency; two congruent words, “high,” sung at the high frequency, and “low,” sung at the low frequency; and two noncongruent words, “high” at low frequency and “low” at high frequency. A sequence of these stimuli was presented monaurally first to one ear, and then to the other. The Stroop effect (the difference between mean RT to congruent words, and mean RT to noncongruent words) was larger for right ear (left hemisphere) presentation. The same experiment was repeated dichotically with a competing message presented to the opposite ear. Again, the Stroop effect was larger for the right ear, and the ear differences were slightly more marked. The result is interpreted as reflecting hemispheric specialization for linguistic and nonlinguistic processing and a model of Stroop conflict in which response competition varies with the relative availability of the conflicting response.
