A year of unprecedented progress in Down syndrome basic research

The years 2006 and 2007 saw the publication of three new and different approaches to prevention or amelioration of Down syndrome effects on the brain and cognition. We describe the animal model systems that were critical to this progress, review these independent breakthrough studies, and discuss the implications for therapeutic approaches suggested by each.     

Anger, disgust, and presumption of harm as reactions to taboo-breaking behaviors

Three experiments investigated the relationship between the presumption of harm in harmfree violations of creatural norms (taboos) and the moral emotions of anger and disgust. In Experiment 1, participants made a presumption of harm to others from taboo violations, even in conditions described as harmless and not involving other people; this presumption was predicted by anger and not disgust. Experiment 2 manipulated taboo violation and included a cognitive load task to clarify the post hoc nature of presumption of harm. Experiment 3 was similar but more accurately measured presumed harm. In Experiments 2 and 3, only without load was symbolic harm presumed, indicating its post hoc function to justify moral anger, which was not affected by load. In general, manipulations of harmfulness to others predicted moral anger better than moral disgust, whereas manipulations of taboo predicted disgust better. The presumption of harm was found on measures of symbolic rather than actual harm when a choice existed. These studies clarify understanding of the relationship between emotions and their justification when people consider victimless, offensive acts.     

Below the Age of Consent: Influences on Moral and Legal Judgments of Adult–Adolescent Sexual Relationships1

Sexual age‐of‐consent violations involving adult–adolescent relationships (AARs) are sometimes viewed with ambivalence by the media and are infrequently prosecuted. Two studies conducted in Britain (where the age of consent is 16) examined influences on disapproval of minimally presented AARs between a 14‐year‐old and a 30‐year‐old. In Study 1, AARs involving an older man were seen as more harmful and objectionable than those involving an older woman. A second study on a jury‐eligible adult population replicated Study 1's gender effects, and also found a difference between legal knowledge and personal belief that the older person had committed a crime. Gender effects in both studies were mediated by perceived harm and emotions.     

The big picture: Writing psychology into the history of the human sciences

The grand narratives which once gave order and readability to histories, of science and of the human sciences are widely rejected in current historiography, and historians focus on detailed studies of scientific knowledge and activity in particular contexts. How, then, are synthetic general histories, accessible to the non-specialist, to be written? This paper, designed as an open-ended discussion, reflects on the business of writing about psychology in a general history of the human sciences. It considers three large topics: reflexivity, and the situation in the human sciences where “man” is both subject and object; the boundary-less identity of the human sciences and hence the need to express values in delimiting the content of the field; and the long-standing debate about what sort of “science” is appropriate for knowledge of human beings. The conclusion turns to “the quest” as a narrative form. © 1998 John Wiley & Sons, Inc.     

Regulating the Private Relations of Adults with Mental Disabilities: Old Laws,New Policies,Hollow Hopes

Recent legislative reforms have aimed to help people with mental disabilities pursue more “normal” lives. Yet, current laws regulating the mentally disableds' private relations continue to disenable them. Social scientists have asserted that people with mental disabilities vary widely in their individual competencies. Yet, laws tend to forgo an individualized approach to the mentally disabled in favor of broad restrictions on their rights to engage in sexual, marital, and parental relationships. Reviews of cases also show that when they challenge these restrictions, the mentally disabled tend to be required to demonstrate a higher level of morality and functioning than non-disabled. Reforming these restrictive legal rules requires an unlikely, but possible, concordance between social science and the law.     

An fMRI study of working memory for schematic facial expressions

Functional magnetic resonance imaging (fMRI) was used to examine neuronal activation in relation to increasing working memory load in an n-back task, using schematic drawings of facial expressions and scrambled drawings of the same facial features as stimuli. The main objective was to investigate whether working memory for drawings of facial features would yield specific activations compared to memory for scrambled drawings based on the same visual features as those making up the face drawings. fMRI-BOLD responses were acquired with a 1.5 T Siemens MR scanner while subjects watched the facial drawings alternated with the scrambled drawings, in a block-design. Subjects had to hold either 1 or 2 items in working memory. We found that the main effect of increasing memory load from one to two items yielded significant activations in a bilaterally distributed cortical network consisting of regions in the occipitotemporal cortex, the inferior parietal lobule, the dorsolateral prefrontal cortex, supplementary motor area and the cerebellum. In addition, we found a memory load x drawings interaction in the right inferior frontal gyrus in favor of the facial drawings. These findings show that working memory is specific for facial features which interact with a general cognitive load component to produce significant activations in prefrontal regions of the brain.     

Internal clock processes and the filled-duration illusion

In 3 experiments, the authors compared duration judgments of filled stimuli (tones) with unfilled ones (intervals defined by clicks or gaps in tones). Temporal generalization procedures (Experiment 1) and verbal estimation procedures (Experiments 2 and 3) all showed that subjective durations of the tones were considerably longer than those of unfilled intervals defined either by clicks or gaps, with the unfilled intervals being judged as approximately 55%-65% of the duration of the filled ones when real duration was the same. Analyses derived from the pacemaker-switch-accumulator clock model incorporated into scalar timing theory suggested that the filled/unfilled difference in mean estimates was due to higher pacemaker speed in the former case, although conclusively ruling out alternative interpretations in terms of attention remains difficult.
