Left non-dominant hand mirror writing

A 38-year-old right-handed woman, who had suffered a left cerebral hemisphere infarction, was studied. She developed right hemiparesis, motor and sensory aphasia, and left hand mirror writing. All possible brain mechanisms involved in writing, either perceptual or motor, were investigated in search of the one responsible for her mirror writing; however, no abnormality was detected. On examination of the left handwriting, in the directionality of writing tracings as related to the body midline, we detected a lack of inversion of the right handwriting motor patterns--at the moment they are transmitted from the left to the right cerebral hemisphere--implicating a motor rather than a perceptual mechanism.     

Asymmetries of comparison

Tversky’s (1977) seminal work on directionality in judgments of similarity demonstrated that people may not judge the similarity of A to B to be equal to the similarity of B to A. In a series of studies, we investigated comparison asymmetries. In Experiment 1, our aim was to extend Tversky’s findings to a heterogeneous stimulus set, but no reliable asymmetries were observed. Experiment 2 employed a variety of comparison judgments, and, although some of these measures showed asymmetries, we still failed to observe asymmetries in rated similarity. A final attempt to obtain asymmetries used direction as a within-subjects factor, and for the first time, rating asymmetries were observed. Our data reinforce the idea of comparison asymmetries but suggest that similarity rating asymmetries are only observed under quite circumscribed conditions.     

Hemispheric local/global processing revisited

Hemispheric differences for local and global processing were assessed with square and rectangular stimulus shapes which contained either squares or rectangles within them. Experiment 1 manipulated the overall size and area of the stimulus items, while experiment 2 kept stimulus area constant and manipulated the number of shapes inside the stimulus. In different conditions subjects judged whether the inside shapes (local processing) or whether the outside shapes (global processing) were squares or rectangles. Reaction time measures revealed that hemispheric differences were unrelated to the local or global processing requirements as well as the spatial frequency of the stimulus texture. A left hemisphere advantage generally was obtained across stimulus and processing conditions, with the pattern of task effects dependent on the specific stimuli employed. The results suggest that the overall stimulus shape rather than processing mode or specific spatial frequency is a primary determinant of hemispheric differences for visual information.     

Role of anxiety and brooding in specificity of autobiographical recall

Overgeneral schemas and lack of autobiographical memory (AM) specificity about our past experiences can predict mood disturbance. Rumination, functional avoidance and executive processes are the main explanatory variables of such overgenerality. However, in non‐clinical samples, rumination predicts overgenerality most consistently after the induction of dysphoric mood. Anxiety also activates rumination. Furthermore, anxiety predicts memory performance and has effects on mood which are independent of the effects of rumination. So, what might be the role of anxiety in autobiographical memory performance? A sample of 210 voluntary participants reported measures of autobiographical memory, anxiety, rumination (brooding and reflection), functional avoidance and executive functions (semantic and phonetic verbal fluency task). Autobiographical performance (specificity) was negatively associated with brooding and age and positively with phonetic verbal fluency but not with functional avoidance and anxiety. However, anxiety and brooding were positively correlated even after controlling for depression scores. Moreover, using structural equation modeling, anxiety showed a significant indirect effect on autobiographical specificity through brooding rumination. These results suggest a possible association of anxiety with autobiographical recall through brooding rumination.     

COMPARISON OF DATA‐COLLECTION METHODS IN A BEHAVIORAL INTERVENTION PROGRAM FOR CHILDREN WITH PERVASIVE DEVELOPMENTAL DISORDERS: A REPLICATION

Cummings and Carr (2009) compared two methods of data collection in a behavioral intervention program for children with pervasive developmental disorders: collecting data on all trials versus only the first trial in a session. Results showed that basing a child's progress on first‐trial data resulted in identifying mastery‐level responding slightly sooner, whereas determining mastery based on all trials resulted in slightly better skill maintenance. In the current replication, no such differences in indication of mastery or maintenance were observed when data were collected on all trials or the first trial.     

Writing therapy in brief workplace counselling: Collaborative writing as inquiry

The purpose of this collaborative research was to reflect on one client's experience of using writing therapy during brief workplace counselling. The client/co‐researcher used expressive and creative writing between counselling sessions, the benefits of which are reported. A brief review of the literature on writing therapy is provided. The focus of the study is on investigating the process of writing therapy from the client's point of view. The epistemological assumptions and research methods are influenced by narrative inquiry. Feminist values inform both the therapeutic practice and research.     

Hypocrites or maligned cooperative participants? Experimenter induced normative conflict in zero-sum situations

The failure to recognize the influence of two distinct forms of moral norms can lead to the misattribution of moral behavior to egoistic motives. This is illustrated in the research of Batson and his colleagues (e.g., Batson, Kobrynowicz, Dinnerstein, Kampf, & Wilson, 1997). They reported the appearance of moral failure and hypocrisy motivation in several experiments employing essentially the same “zero-sum” experimental situation. They cited as evidence the discrepancy between participants’ apparently self-serving private acts and their subsequent public ratings of the morality of what they had done as well as their recognition of the “most” moral way to behave. The research reported here supported an alternative explanation that located the experimenter’s implicit and explicit instructions as the source of the discrepancy between the participants’ private acts and their public ratings. The findings confirmed the hypothesis that Batson and his colleagues had not merely made moral norms “salient”. They had actually presented their participants with contradictory “demands”: explicitly inviting them to meet the norm of justified self-interest in private but then give public lip-service to the experimenter’s instructions as to a supererogatory way to behave. When either of the demands was removed, the “hypocrisy” no longer occurred.     

Changing Me,Changing Us: Relationship Quality and Collective Efficacy as Major Outcomes in Systemic Couple Therapy

We examine the sensitivity to change in the Evaluation of Social Systems (EVOS) scale, which assesses relationship quality and collective efficacy. In Study 1 we conducted a waitlist‐control, short‐term couple therapy RCT study (N = 43 couples) with five systemic therapy sessions treating communication and partnership problems; our intent was to provide high external validity. Construct validity of EVOS was assessed by comparison with additionally applied scales (Family Scales; Outcome Questionnaire, OQ‐45.2). In Study 2, N = 332 individuals completed an experiment with high internal validity in order to verify sensitivity to change in three different social contexts. Results from Study 1 revealed a significant increase in relationship quality in the treatment group directly after treatment, as compared to the control group. Sensitivity to change was slightly better for EVOS than for other measures. While this positive change could not be fully sustained between posttreatment and a 4‐week follow‐up, EVOS score did not fall below baseline and pretreatment levels, supporting moderate‐to‐large sensitivity to change. Study 2 supported high sensitivity to change in EVOS for couple relations, family relations, and work‐team relationships. Therefore, EVOS can be used as an outcome measure to monitor the process of systemic interventions focusing on relationship quality and collective efficacy. Due to its sensitivity to change, EVOS can provide evidence for treatment success with regard to relationship aspects.
