Intergenerational potential: effects of social interaction between older adults and adolescents

The present study aimed to investigate the potentially facilitative effect of the interaction between older adults and adolescents. For older adults, the interaction was expected to compensate for age-related deficits (e.g., cognitive performance, cognitive-affective complexity). In case of the adolescents, an optimization of development was expected (e.g., prosocial behavior, communion goals). Ninety older women (70-74 years) and 90 adolescent girls (14-15 years) were randomly assigned to 3 experimental conditions. In each of the conditions, nonfamiliar dyads collaborated on 1 task. The conditions varied according to the age composition and the type of contextual demand (high vs. low support of generativity [older adults] and identity formation [adolescents]). Individual performance measures were assessed immediately after the interaction. As expected, intergenerational settings characterized by high support of generativity and identity formation resulted in more prosocial behavior in adolescents. Furthermore, the results lent partial support to the hypothesis that in older adults, this setting facilitated higher complexity of emotion regulation as well as higher levels of performance in measures of speed and word fluency.     

Toward a dialect theory: cultural differences in the expression and recognition of posed facial expressions

Two studies provided direct support for a recently proposed dialect theory of communicating emotion, positing that expressive displays show cultural variations similar to linguistic dialects, thereby decreasing accurate recognition by out-group members. In Study 1, 60 participants from Quebec and Gabon posed facial expressions. Dialects, in the form of activating different muscles for the same expressions, emerged most clearly for serenity, shame, and contempt and also for anger, sadness, surprise, and happiness, but not for fear, disgust, or embarrassment. In Study 2, Quebecois and Gabonese participants judged these stimuli and stimuli standardized to erase cultural dialects. As predicted, an in-group advantage emerged for nonstandardized expressions only and most strongly for expressions with greater regional dialects, according to Study 1.     

Differences in inter-rater reliability and accuracy for a treatment adherence scale

Inter-rater reliability and accuracy are measures of rater performance. Inter-rater reliability is frequently used as a substitute for accuracy despite conceptual differences and literature suggesting important differences between them. The aims of this study were to compare inter-rater reliability and accuracy among a group of raters, using a treatment adherence scale, and to assess for factors affecting the reliability of these ratings. Paired undergraduate raters assessed therapist behavior by viewing videotapes of 4 therapists' cognitive behavioral therapy sessions. Ratings were compared with expert-generated criterion ratings and between raters using intraclass correlation (2,1). Inter-rater reliability was marginally higher than accuracy (p = 0.09). The specific therapist significantly affected inter-rater reliability and accuracy. The frequency and intensity of the therapists' ratable behaviors of criterion ratings correlated only with rater accuracy. Consensus ratings were more accurate than individual ratings, but composite ratings were not more accurate than consensus ratings. In conclusion, accuracy cannot be assumed to exceed inter-rater reliability or vice versa, and both are influenced by multiple factors. In this study, the subject of the ratings (i.e. the therapist and the intensity and frequency of rated behaviors) was shown to influence inter-rater reliability and accuracy. The additional resources needed for a composite rating, a rating based on the average score of paired raters, may be justified by improved accuracy over individual ratings. The additional time required to arrive at a consensus rating, a rating generated following discussion between 2 raters, may not be warranted. Further research is needed to determine whether these findings hold true with other raters and treatment adherence scales.     

Place‐value understanding in number line estimation predicts future arithmetic performance

In multi‐digit numbers, the value of each digit is determined by its position within the digit string. Children's understanding of this place‐value structure constitutes a building block for later arithmetic skills. We investigated whether a number line estimation task can provide an assessment of place‐value understanding in first grade. We hypothesized that estimating the position of two‐digit numbers requires place‐value understanding. Therefore, we fitted a linear function to children's estimates of two‐digit numbers and considered the resulting slope as a measure of children's place‐value understanding. We observed a significant correlation between this slope and children's performance in a transcoding task known to require place‐value understanding. Additionally, the slope for two‐digit numbers assessed at the beginning of grade 1 predicted children's arithmetic performance at the end of grade 1. These results indicate that the number line estimation task may indeed constitute a valid measure for first‐graders' place‐value understanding. Moreover, these findings are hard to reconcile with the view that number line estimation directly assesses a spatial representation of numbers. Instead, our results suggest that numerical processes involved in performing the task (such as place‐value understanding) may drive the association between number line estimation and arithmetic performance.     

Visual-spatial processing in deaf brain-damaged signers

Sign language displays all the complex linguistic structure found in spoken languages, but conveys its syntax in large part by manipulating spatial relations. This study investigated whether deaf signers who rely on a visual-spatial language nonetheless show a principled cortical separation for language and nonlanguage visual-spatial functioning. Four unilaterally brain-damaged deaf signers, fluent in American Sign Language (ASL) before their strokes, served as subjects. Three had damage to the left hemisphere and one had damage to the right hemisphere. They were administered selected tests of nonlanguage visual-spatial processing. The pattern of performance of the four patients across this series of tests suggests that deaf signers show hemispheric specialization for nonlanguage visual-spatial processing that is similar to hearing speaking individuals. The patients with damage to the left hemisphere, in general, appropriately processed visual-spatial relationships, whereas, in contrast, the patient with damage to the right hemisphere showed consistent and severe visual-spatial impairment. The language behavior of these patients was much the opposite, however. Indeed, the most striking separation between linguistic and nonlanguage visual-spatial functions occurred in the left-hemisphere patient who was most severely aphasic for sign language. Her signing was grossly impaired, yet her visual-spatial capacities across the series of tests were surprisingly normal. These data suggest that the two cerebral hemispheres of congenitally deaf signers can develop separate functional specialization for nonlanguage visual-spatial processing and for language processing, even though sign language is conveyed in large part via visual-spatial manipulation.     

Sometimes a Bear is Just a Bear: No Evidence of Nonclinical Adult Toy Animal Ownership Indicating Emotion Dysregulation

Although some studies of clinical populations suggest an association of adult toy animal ownership with personality disorder, studies of nonclinical populations have been lacking. In a nonclinical young adult sample (N?=?148), we found no association of toy animal ownership with use of immature, mature, or neurotic defense mechanisms; avoidant or anxious attachment style; trait conscientiousness; heart rate variability (an index of self-regulatory strength); or social desirability responding. The results do not provide evidence for an association of adult nonclinical toy animal ownership with psychological or psychophysiological indices of immaturity, conscientiousness, insecure attachment, or lack of self-regulatory strength.     

Christianity and Feminism: Do they need each other?

Abstract

This article presents personal reflections on the relationship between Christianity and feminism. It argues that Christian ideas have influenced the historical development of feminism, and that there exists a continuing affinity between some debates of the contemporary secular women's movement and those of committed Christian feminists. It presents an historical example front the nineteenth century which shows how Christian and early feminist ideas were combined in the work of Florence Nightingale. It then discusses the global empowerment of women in relation to the challenge and opportunity this poses for the Christian churches, and reflects on the wisdom of women as an important source for Christian renewal. The article argues that Christianity and feminism both challenge and need each other for mutual transformation. Without a rightly understood feminism Christianity will not remain true to its own nature and, without Christianity or rather without religion and spirituality, feminism will lack an essential source of empowerment. It also raises the question of what difference the participation of women will make to the future of Christian theology.
