Religious disagreements and epistemic rationality

Richard Feldman has argued that in cases of religious disagreement between epistemic peers who have shared all relevant evidence, epistemic rationality requires suspense of judgment. I argue that Feldman’s postulation of completely shared evidence is unrealistic for the kinds of disputes he is considering, since different starting points will typically produce different assessments of what the evidence is and how it should be weighed. Feldman argues that there cannot be equally reasonable starting points, but his extension of the postulate of completely shared evidence to evidence for starting points involves an illicit assimilation of ordinary cases of evidence assessment to cases in which substantial agreement about background assumptions is lacking. I also clarify why even if Feldman were correct about what epistemic norms require, his conclusion would not show that we should actually suspend judgment about religious or anti-religious truth claims.     

The development of a systemic school-based intervention: Marte Meo and coordination meetings

Antisocial behavior is often persistent, and in addition to causing suffering to children and their families, it also poses considerable costs for society. Children who display externalizing behavior in their early years run a high risk of having severe problems later in life. There is a need for treatment methods that may be used in various settings because these children constitute a group that is hard to reach with conventional treatment methods. In addition, the dropout rate from ordinary treatment is often high. In the present study, a systemic school-based model for early detection and intervention among 4-12-year-old children who displayed externalizing behavior problems was developed and examined in a nonrandomized study in the county of Skaraborg in Sweden. The intervention was collaborative and included a combination of the Marte Meo model and coordination meetings based on systemic theory and practice. Treatment effects in the group who had received the intervention were compared with a group who had received treatment as usual in their ordinary school setting. Assessments were carried out before, and 2 years after, the intervention. For the intervention group (N = 33), there was a significant decrease in the children's reported symptoms in school and in the home. No decrease in externalizing behavior was found in the comparison group (N = 16). There were no dropouts in the intervention group after the intervention had begun. The results are promising; the study demonstrates that it is possible to work effectively with many children who display externalizing behavior problems in a nonclinical setting.     

Maternal soothing and infant stress responses: soothing, crying and adrenocortical activity during inoculation

The relation between maternal soothing and infant stress response during inoculation was examined in a sample of 37 mothers and their 3-month-old infants. The mothers' soothing and the infants' cry vocalizations and the mothers' and the infants' salivary cortisol level pre- and post-injection were analysed. There was a positive relation between infants' cry vocalization post-injection and maternal soothing pre- and post-injection. The sample was divided in two sub-groups depending on whether the mothers evidenced most soothing of the infants in the period before (Preparatory group; n=20) or after (Contingent group; n=17) the syringe injection. In the Preparatory group, the duration of infant cry vocalizations was related to amount of maternal soothing before and after the injection, while cry vocalizations in the Contingent group was related to amount of maternal soothing after the injection. The Contingent infants responded to the injection with a significant increase in cortisol, while there was no increase in the Preparatory infants. The Preparatory infants evidenced significantly longer duration of looking at the target stimuli in a visual marking task, suggesting greater difficulties in disengaging attention. These findings indicate that 3-month-olds' stress responses and their mothers' situational behaviour are mutually regulated.     

Change during and after long-term analytic group psychotherapy

There are very few empirical studies of long-term, analytic group psychotherapy. Sixty-nine patients in long-term analytic group psychotherapy were evaluated from pretherapy to posttherapy, and one year after termination. The primary outcome measures were the Symptom Checklist-90 (Revised) and the Inventory of Interpersonal Problems. In addition, the Global Assessment of Functioning (GAF) was scored independently by two evaluators. The average time in treatment was 32.5 months. The patients improved significantly during treatment, up to 30 months, on all measures. The improvement continued during the follow-up period. Sixty to 86% of the patients were recovered or significantly changed at follow-up.     

Intervening factors in the utilization of social research

In Swedish welfare agencies, it was found that the importance of characteristics of social research for utilization was related to three intervening factors: the context of origin of the research, the functions for the user and the utilization context. These factors seem to explain the difference between competing notions on the importance of scientific sophistication for research utilization. Sune Sunesson is professor and head of the Ph.D. program and the research department of the School of Social Work at Lund University. His main research interests are the sociology of human service organizations and the impact of science on these organizations. Kjell Nilsson, Birgitta Ericson, and Britt-Marie Johansson are Ph.D. candidates in the Department of Sociology of the Lund University.     

Very short term recognition memory for odors

An investigation of very short term olfactory recognition memory was made with odors of low familiarity to subjects. The experimental procedure was that currently used to make qualitative similarity judgments on odors delivered in paired succession. Subjects made similarity judgments in a yes/no recognition paradigm on odors that were either identical or different. The dependence of recognition performance upon the degree of qualitative similarity was assessed by using two sets of dissimilar odor pairs: slightly dissimilar pairs (S1) and very dissimilar pairs (S2). Performance in terms of correct judgments (hits, correct rejections) was rather good for identical pairs in both sets and was nearly perfect for very dissimilar pairs with a delay of 2–300 sec, suggesting no effect of time or similarity on performance. However, for slightly dissimilar pairs, false alarms increased in number, thereby indicating a dependence of the recognition score on the qualitative distance between odors. In addition, false alarms tended to increase with the lengthening of the retention interval. It was suggested that the subjects based their responses on their capability to detect differences between odors rather than recognizing their similarities. Correct identifications were thus preserved at the cost of increasing false alarms when the discrimination task was made more difficult by closer similarity between odors (S1) or by the fading of memory traces with time. Studying the congruence between the similarity judgments and the kind of evocations associated with paired odors gives some support to the view that recognition performances had some cognitive/semantic basis.     

Emotional modulation of attention orienting: A classical conditioning study

Emotional modulation of attention shifting was investigated in Posner's (1980) spatial orienting task by conditioning the attention cue to an aversive white noise. Prior to the attention task, the Conditioning group received a 90dB white noise unconditioned stimulus (UCS) contingent upon the frame-lit rectangle attention cue, while the Control group received non-contingent presentations. The Conditioning group evidenced greater skin conductance responses to the frame-lit rectangle in the conditioning phase, reflecting an electrodermal conditioned response. In the attention phase, the frame-lit rectangle served as the attention cue in the spatial orienting task. The Conditioning group showed equally fast reaction times (RTs) to targets presented outside the location of the cue as to targets at the same location as the cue, reflecting elimination of the cognitive cost usually involved in shifting attention. The Control group evidenced the regular cost of shifting attention away from the location of the cue. The Conditioning group also evidenced a larger N1-component with a parietal distribution of the event-related brain potentials to the cue and a larger N1-component at the frontal regions to targets presented outside the cued location. This suggests that both visual orienting to the cue and attention shifting from cue to target on invalid trials were amplified by the emotional salience attached to the cue through the classical conditioning procedure.     

Infant attention and the development of smooth pursuit tracking.

The effect of attention on smooth pursuit and saccadic tracking was studied in infants at 8, 14, 20, and 26 weeks of age. A small rectangle was presented moving in a sinusoidal pattern in either the horizontal or vertical direction. Attention level was distinguished with a recording of heart rate. There was an increase across age in overall tracking, the gain of the smooth pursuit eye movements, and an increase in the amplitude of compensatory saccades at faster tracking speeds. One age change was an increase in the preservation of smooth pursuit tracking ability as stimulus speed increased. A second change was the increasing tendency during attentive tracking to shift from smooth pursuit to saccadic tracking when the stimulus speed increased to the highest velocities. This study shows that the development of smooth pursuit and targeted saccadic eye movements is closely related to the development of sustained attention in this age range.     

Gender and Grade Differences in Latent Ability Variables

Scores in ability tests administered to students in grades 4–9 were simultaneously factor-analyzed within twelve gender by grade groups. Gender and grade differences in means and variances were studied for five latent ability factors according to a hierarchical model and compared with means and variances in the observed scores.
Girls had higher means than boys in a general ability factor (G), in a residual general speed factor (Gs') and in a residual factor of numerical facility (N'). Boys were higher in a residual vocabulary factor (V') and most of all in a residual spatial visualization factor (Vz'). Boys had larger variances than girls in N' and Gs'. In general the differences in means and variances were in the same direction for the closest corresponding observed scores, but some striking discrepancies between latent and observed scores were found. As a rule, the discrepancies were due to the complexity of the tests where one factor could compensate for another.
In the discussion it was pointed out that some of the differences found were likely to have changed between the testing in the late 1950s and the present. Nevertheless the demonstration of the divergence between analyses of latent vs. observed scores remains valid.
