BROGAARD'S MORAL CONTEXTUALISM

Brogaard's non-indexical version of moral contextualism has two related problems. It is unable to account for the function of truth-governed assertoric moral discourse, since it leaves two (semantically clearheaded) disputants without any incentive to resolve seemingly contradictory moral claims. The moral contextualist could explain why people do feel such an incentive by ascribing false beliefs about the semantic workings of their own language. But, secondly, this leaves Brogaard's moral contextualism looking weaker than a Mackie-style invariantist error theory about morals. The latter is equally non-objectivist, but less revisionist, since it takes the semantics of moral discourse at face value, and can also explain all of Brogaard's other linguistic evidence.     

Ingroup bias in the minimal group paradigm shown by three‐person groups with high or low state self‐esteem

From social identity theory a negative relation between self‐esteem and ingroup bias can be deducted. Much research has been done to test this proposition and largely failed to confirm this relation. Unlike many existing studies, we conducted an experiment in which (a) self‐esteem is not conceived as a trait entity but much more situation‐specific, (b) the self‐esteem manipulation is not relative to the outgroup, and (c) the measure of intergroup differentiation is unrelated to the self‐esteem manipulation. We categorised our participants into two arbitrary minimal groups (Klee or Kandinsky fans) and afterwards formed homogeneous three‐person groups (all persons were either Klee or Kandinsky fans). We manipulated the state self‐esteem of these real groups by giving them positive or negative feedback concerning their performance in a problem‐solving task. Afterwards, all groups distributed money to ingroup and outgroup members via Tajfel distribution matrices. Low state self‐esteem groups were found to exhibit stronger ingroup bias than high state self‐esteem groups overall, although the variability of intergroup discrimination was larger in the low state self‐esteem groups, pointing to more heterogeneous reactions to low state self‐esteem.

Implicit Learning in Aging: Extant Patterns and New Directions

Research suggests that the striatum plays an important role in implicit learning (IL). The striatum exhibits marked age-related morphological and neurochemical losses. Yet, behavioral studies suggest that IL is generally well preserved in old age, and that age-related differences emerge only when highly complex IL tasks are used. In this review, we integrate behavioral and neuroimaging evidence on IL in aging. We suggest that relative stability of IL in old age may reflect neural reorganization that compensates for age-related losses in striatal functions. Specifically, there may be an age-related increase in reliance on extrastriatal regions (e.g., medial-temporal, frontal) during IL. This reorganization of function may be beneficial under less taxing performance conditions, but not when task demands become more challenging.     

Stability of Typical Patterns of Subjective Well-Being in Middle-Aged Swedish Women

Typical patterns of general subjective well-being (SWB) were searched for in a representative longitudinal sample of Swedish women (N = 272) at age 43 and 49. Cluster analysis at each age separately resulted in a six-cluster solution at both ages. The two solutions were similar, indicating structural stability across 6 years. Five of the six clusters also showed significant individual stability. Among these clusters, a generalized positive typical pattern and two generalized negative typical patterns were found, one characterized by very high negative affect and one characterized by very low global life satisfaction. A cluster characterized by above average positive and negative affect was also found as well as one characterized by low positive affect. A strong relationship was found between membership in an extreme cluster and the values in certain SWB-related variables, supporting the validity of the typical patterns found. Further, it was shown that cluster membership contributed to the prediction of some validation variables above the prediction achieved by using only SWB components entered as continuous variables, suggesting the presence of interactions and nonlinearities in the SWB area.     

Behavioral phenotyping of a murine model of Alzheimer’s disease in a seminaturalistic environment using RFID tracking

Neurodegen erative disorders such as Alzheimer’s disease (AD) are increasingly threatening public health. Most animal models of AD consist of transgenic mice that are usually housed singly or in unisexual groups in small barren cages. Such restricted environments, however, prevent the mice from showing a variety of speciesspecific behaviors and consequently may constrain comprehensive behavioral phenotyping. On the other hand, allowing the animals to freely organize their lives in a spacious physically and socially enriched environment makes behavioral phenotyping laborious and time consuming. Radio frequency identification (RFID) using a network of antennae and small glass-coated transponders labeling each individual allows for gathering spatiotemporal information about a large number of individuals in parallel. The aim of this project was to use the RFID technique to facilitate the characterization of mice carrying a genetic disposition to develop AD-like pathology and of their wild-type conspecifics in a spacious seminaturalistic environment.     

Predictors and outcomes of persistent or age‐limited registered criminal behavior: a 30‐year longitudinal study of a Swedish urban population

This study uses data from the longitudinal research program Individual Development and Adaptation, where an entire school‐grade cohort of children in a middle‐size Swedish city (n～1.300) has been followed from ages 10 to 43 and 48 for women and men, respectively. Our findings indicate that the patterns of offending across the life‐course differ between genders, where males seem to initiate their offending earlier than females. Further, there are very few women on a persistent offending‐trajectory. Focusing on precursors to as well as consequences of offending as indexed in official registers, our results indicate that individuals in the persistent offender group have the most pronounced adjustment problems in school‐ as well as in middle age. Individual characteristics and behaviors (e.g., aggression, hyperactivity, antisocial behavior) vary systematically between individuals with different developmental offending patterns. The combination of an unstable upbringing and own antisocial behavior seems to be especially predictive for criminality. For persistent offenders, the prevalence of alcohol and psychiatric problems at adult age is high for males and extremely high for females (nine out of ten and six out of ten for each of the two problem types for females). Further, the importance for adjustment of the two‐dimensional variation in the number of crimes committed during adolescence and adult age seems to have been surprisingly well captured by the “crude” division into the four offender groups that were used.

Incidental retrieval processes influence explicit test performance with data-limited cues

In two experiments, the influence of incidental retrieval processes on explicit test performance was tested. In Experiment 1, subjects studied words under four conditions (auditory-shallow, auditory-deep, visual-shallow, and visual-deep). One group of subjects received auditory and visual word-fragment completion; another group received auditory and visual word-fragment cued recall. Results indicated that changes in sensory modality between study and test reduced both recall and priming performances; levels of processing significantly affected only the cued recall test. These results indicated that incidental retrieval processes might affect explicit test performance when retrieval cues are data limited. Experiment 2 supported this conclusion by showing an effect of matching study and test modalities on explicit test performance with fragment but not with copy cues. Taken together, these results support Roediger and McDermott’s (1993) suggestion that explicit test performance is influenced by incidental retrieval processes when data-limited retrieval cues are used.     

Is all therapy just a placebo effect?

The epistemological soundness of controlled clinical trials is questioned. It is argued that the real effect of therapies cannot be determined by such experiments because there is a significant interaction between the placebo effect and real effect created by the individual therapist and treatment situation which, however, is neglected in controlled clinical trials. This critical standpoint is supported by several pharmacological examples.     

Gerotranscendence and the Functions of Reminiscence

In the present investigation, different functions of reminiscence have been empirically studied in relation to the developmental changes described in the theory of gerotranscendence, a theory dealing with human development towards maturity and wisdom. The phenomenon of gerotranscendence and the functions of reminiscence are, according to our analyses, intertwined. Since gerotranscendence is largely about the change and reconstruction of identity and personal frames of reference, this also means that the common continuity-oriented theoretical perspective on reminiscence has to be questioned. Reminiscence can have functions other than that of stabilizing an already developed identity. It can just as well play an instrumental role in developmental change and reconstruction of the identity and in our perception of the world.     

A component analysis of action events

Summary Three experiments are reported, that examine the basis of the recall superiority of subject-performed tasks (SPTs) over verbal-memory tasks (VTs), and the interitem variability for SPTs. In Experiments 1 and 2 a component analysis of SPTs is undertaken in order to explore the importance of (a) involvement of external objects, (b) multimodality, and (c) enactment, for the superior memory performance for SPTs over that for VTs. In Experiment 3 the role of retrieval support, in terms of a high degree of match between the encoding and retrieval situations, was investigated in order to find out why some SPTs are easier to recall than others. The results indicate that it is difficult to separate out a single component as the most critical one for the superiority of SPT recall over VT recall, and that a high degree of match between encoding and retrieval conditions improves SPT recall. It is suggested that, in order to explain the large differences in memorability between SPTs and VTs, it is sufficient to consider the more supportive encoding situation for SPTs, but to explain differences in recallability between various SPTs, the compatibility between encoding and test has to be taken into consideration.
