Implicit self and the right hemisphere: Increasing implicit self‐esteem and implicit positive affect by left hand contractions

Unilateral hand contraction typically activates the contralateral hemisphere and has led to changes in psychological states and performances in previous research. Based on a right hemisphere model of the implicit self, we hypothesized and found that left hand contraction increases momentary levels of implicit self‐esteem (Studies 1 and 2) and implicit positive affect (Study 3). The findings are discussed with respect to potential differences between the hemispheres in implicit and explicit affective processing and how they can be integrated in the existing literature on hemisphere asymmetries.     

Exploratory study of mindfulness in modern-day sport psychology consulting relationships

This study explored sport psychology practitioners’ mindfulness in relation to the quality of consulting relationships and value within contemporary practice. A total of 34 sport psychology practitioners from South Africa (n = 22, females = 41%) and the United Kingdom (n = 12, females = 25%) (Private practice = 68%; 15+ years’ experience = 44%) participated in this study. Data were gathered, using the Five Factor Mindfulness Questionnaire (FFMQ-SF), Working Alliance Inventory Short-Revised Form (WAI-SRT), and interviews. Spearman’s rank order correlation and thematic content analyses were employed to analyse the data. Higher levels of practitioners’ mindfulness were associated with superior consulting relationships. Specifically, positive correlations were observed between mindfulness attributes of observing, describing, non-reacting ability, and quality of the therapeutic bond, agreement on goals, and agreement on goals and tasks with clients respectively. Thematic analysis suggested mindfulness to facilitate accurate attending to present-moment experiences, and empathetic understanding of clients’ unique needs.     

Do Unilateral Right and Left Face Contractions Induce Positive and Negative Emotions? A Further Test of Schiff and Lamon's (1989) Hypothesis

Schiff and Lamon (1989) proposed that unilateral face contractions induce positive or negative changes in emotion depending on the side of contraction; support for this proposal, however, has been mixed. In a new test, 40 right-handed and 38 left-handed men performed four alternating face contractions (LRLR or RLRL) and, after each one, completed a different version of the Depression Adjective Checklist (Lubin, 1994). A repeated-measures ANCOVA failed to reveal any significant effect of side of face contraction or handedness on direction of emotion change. Instead, regardless of side of contraction, the subjects' negative emotional state increased significantly across the four contractions with the degree of change being significantly related to the subjects' reported level of difficulty in holding the contraction irrespective of whether the more difficult side was the left or the right.     

Inner Harmony and the Human Ideal in Republic IV and IX

This paper presents an interpretation of Plato's moral psychology in two books of the Republic that construes Plato as adopting a strong unity for the moral agent. Within this conception reason influences both emotion and action directly. This view is contrasted with the current prevailing interpretation according to which all three parts of the soul have their own reason, feeling, and desire. The latter construal is shown to be both philosophically weak, and less plausible as a historical reconstruction.     

Probing the human brain with stimulating electrodes: The story of Roberts Bartholow’s (1874) experiment on Mary Rafferty

Roberts Bartholow’s 1874 experiment on Mary Rafferty is widely cited as the first demonstration, by direct application of stimulating electrodes, of the motor excitability of the human cerebral cortex. The many accounts of the experiment, however, leave certain questions and details unexamined or unresolved, especially about Bartholow’s goals, the nature and quality of the evidence, and the experiment’s role in the history of theory and research on localisation of function. In this article, we try to fill these gaps and to tell the full story. We describe Bartholow’s career up to 1874, review the theoretical and empirical background for the experiment, and present Bartholow’s own account of the experiment as well as those of his supporters and critics. We then present our own analysis, assess the experiment’s influence on contemporaneous scientific opinion about cortical excitability, and trace its citation record into our own time. We also review and assess ethical criticisms of Bartholow and their effects on his career, and we close by discussing the role we think the experiment deserves to play in the history of theory and research on cortical excitability.     

Spontaneous head positions in infants during the first 9 postnatal months

The developmental organization of spontaneous head positioning over the first 9 postnatal months of life was investigated in a study of 35 infants. Head positions assumed by infants while at rest were recorded at 11 observation period: at 1 week, 2 weeks, 4 weeks of age, and every 4 weeks thereafter until the infant was 36 weeks old. Results indicated an overall tendency toward a head-right position, which was strongest during the neonatal period, but declined with age. The head-right position bias was qualified by familial handedness.
