Is Memory for Head Orientation Based on a Left-Looking Schema?

Research has shown that people misremember right-looking heads on coins as facing to the left, suggesting a general memory schema that favors left-lookers. This hypothesis was investigated in a study of 241 subjects in three experiments who were shown photographs of faces looking to the left, to the right, or at the observer and were later asked to identify whether each one had subsequently been left-right reversed. Also, in Experiments 2 and 3, respectively, initial judgments of liking and of orientation were obtained. Unexpectedly, orientation memory accuracy was lower after a 5-s exposure than after a 1-s exposure, and after initial judgments of lateral orientation than after judgments of liking. Although the difference between left- and right-lookers was significant in only 2 of 14 comparisons, aggregated data showed that identification accuracy was generally higher for left-lookers, with a mean effect size of 0.16. Although small, this difference is consistent with the hypothesis of a left-looking schema for heads.     

Haloperidol-induced Mood and Retrieval of Happy and Unhappy Memories

The present study investigated the effect of haloperidol-induced mood in normal healthy male volunteers on the retrieval of memories of real-life personal experiences using a between-subjects double-blind design. Forty subjects were required to retrieve past real life experiences associated with a series of stimulus words following administration of a single oral dose of 5mg haloperidol or placebo. The experiences were subsequently rated by subjects for their happiness felt at the time of the original experience. A significant decline in self-reported hedonic tone was observed in subjects given haloperidol. In addition, subjects on placebo recalled a significantly greater percentage of happy memories than subjects who were on haloperidol; a trend for a reverse pattern was observed for unhappy memories. The effects of the drug on the retrieval of memories were only in part mediated by the decline in hedonic tone scores. The effects of haloperidol are interpreted in terms of drug-induced dysphoria.     

Matching Methods for Selection of Participants for Follow-Up

This work examines ways to make the best use of limited resources when selecting individuals to follow up in a longitudinal study estimating causal effects. In the setting under consideration, covariate information is available for all individuals but outcomes have not yet been collected and may be expensive to gather, and thus only a subset of the comparison participants are followed. Expressions in Rubin and Thomas (1996) Rubin, D. B. and Thomas, N. 1996. Matching using estimated propensity scores, relating theory to practice.. Biometrics, 52: 249–264. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar] show the benefits that can be obtained, in terms of reduced bias and variance of the estimated treatment effect, of selecting comparison individuals well matched to those in the treated group compared with a random sample of comparison individuals. We primarily consider nonexperimental settings but also consider implications for randomized trials. The methods are illustrated using data from the Johns Hopkins University Baltimore Prevention Program, which included data collection from age 6 to young adulthood of participants in an evaluation of 2 early elementary-school-based universal prevention programs.     

Post-Christendom,Post-Constantinian,Post-Christian … Does the Label Matter?

The demise of Christendom is of fundamental significance in understanding the present and future relationship between the churches and European culture. Attempts to develop post-Christendom perspectives are hindered by linguistic and conceptual confusion. This article explores misleading implications of the terms ‘post-Constantinian’ and ‘post-Christian’ and argues for the consistent use of the term ‘post-Christendom’. Use of the terms ‘Christendom’ and ‘post-Christendom’ has been criticised for failing to differentiate between different kinds of Church–state partnerships, some of which may be less problematic than others. This article acknowledges such historical differences but argues that there is an underlying ideological unity susceptible of being described and investigated under these labels. It argues further that attempts to promote a benign expression of Christendom as a possible future for Europe are unwise. It summarises the transitions occurring as Europe journeys beyond Christendom and argues for creative engagement with post-Christendom as an opportunity for ecclesial renewal.     

Drive for muscularity and muscularity-oriented disordered eating in men: The role of set shifting difficulties and weak central coherence

Set shifting difficulties and weak central coherence are information-processing biases associated with thinness-oriented eating and body image pathology in women. However, little is known about the relationship between these processing biases and muscularity-oriented eating and body image pathology. We investigated whether set shifting and central coherence were uniquely related to the drive for muscularity and muscularity-oriented disordered eating in a sample of 91 male undergraduates. Participants completed the Wisconsin Card Sort Test, the Matching Familiar Figures Task, the Drive for Muscularity scale, and a modified Eating Disorders Examination-Questionnaire. Results indicated that set shifting difficulties and weak central coherence were both uniquely positively associated with the drive for muscularity, and that set shifting difficulties were uniquely positively associated with muscularity-oriented disordered eating. Results are discussed with regard to the male experience of body image and eating pathology, and in regard to muscle dysmorphia.     

Resolving contradictory findings on sex and social class differences in children's responses to reinforcement

Contradictory results have been reported on the effectiveness of various reinforcers with children of different ages and socioeconomic classes. The present study considered the relative effectiveness of two types of verbal and one type of tangible reinforcement on a two-choice discrimination task (marble-in-the-hole) for preschool children. IQ and operant level were treated as covariates and accounted for the observed differences in performance between the 24 middle-class and 24 lower-class children and between the 24 males and 24 females. Disparate findings of previous studies regarding sex and social class differences might have been reconciled if baseline and IQ had been considered.
