Understanding alexithymia in female adolescents: The role of attachment style

Adults with alexithymia retrospectively report emotional difficulties with caregivers during childhood. However, the association between attachment style and alexithymic traits may be evident at an earlier stage than adulthood, i.e. during adolescence. Sixty school-based healthy females aged 9–18 years (mean 14.08, SD 2.71 years) participated in an Attachment Style Interview (ASI) and completed the Toronto Alexithymia Scale (TAS-20). Greater levels of alexithymia were exhibited by both anxious and avoidant insecurely attached groups compared to securely attached participants. Fear of separation (characteristic of anxious attachment style) predicted both overall alexithymia scores and the specific alexithymic trait of ‘difficulty identifying feelings’ (DIF). Constraints on closeness (an avoidant attachment attitude) predicted ‘difficulty describing feelings’ (DDF). Low felt attachment to primary caregiver was a predictor of ‘externally oriented thinking’ (EOT). These findings indicate that features of anxious and avoidant insecure attachment styles are differentially related to the separate facets of alexithymia in female adolescents. Specifically, the findings concerning fear of separation may reflect the adolescent struggle for autonomy and the resulting effects on the affect regulation system. Our results also suggest that the normative differentiation of the emotional and cognitive aspects of alexithymia may occur on a developmental trajectory.     

MODIFICATION OF HUMAN GASTRIC ACID SECRETION WITH OPERANT-CONDITIONING PROCEDURES1

In an attempt to control gastric acid secretion with operant-conditioning techniques, four normal women were given visual feedback on gastric pH plus money reinforcers. When money was made dependent on increased secretion in a differential-reinforcement-of-high-rates schedule, the rate of secretion of three of the four subjects increased to three times baseline. When money was then made dependent on decreased secretion in a differential-reinforcement-of-other-behaviors schedule, the rate of secretion of these three subjects returned to baseline levels. Heart rate, respiratory frequency, abdominal electromyographic activity, and stomach motility (measured by the electrogastrogram method) were not consistently correlated with acid secretion across subjects, although individual subjects showed substantial correlations between acid secretion and one or more other physiological response.     

The Ecology of Self-Injury: A Multivariate Approach

ABSTRACT: In an ecological study of the distribution of self-injury in London, Canada, the authors found that self-injury occurred more frequently in the central areas of the city. Multivariate analysis revealed that living arrangements, such as high density of housing and single-person households, are closely associated with inflated rates on self-injury. Low socio-economic status is also related to self-injury but neither family status nor mobility are significant predictors. Ecological relationships such as these suggest directions for future research on individuals and may also be of direct use to planners who wish to locate treatment services advantageously.     

The Psychosocial Vulnerability Model of Hostility as a Predictor of Coronary Heart Disease in Low-income African Americans

The current study examined social support and stress as mediators of the hostility—coronary heart disease (CHD) relationship as suggested by the psychosocial vulnerability model in a sample of low-income African Americans. Among 95 CHD patients and 30 healthy controls, hostility was negatively correlated with social support, but was not related to minor stress. CHD patients endorsed higher levels of hostility; however, the relationship between hostility and CHD status was diminished once stress and social support were included in the model. This study lends partial support for the psychosocial vulnerability model of hostility in African Americans, but suggests that the relationship between hostility and stress may be impacted by socioeconomic status.     

Evidence for a distributed hierarchy of action representation in the brain

Complex human behavior is organized around temporally distal outcomes. Behavioral studies based on tasks such as normal prehension, multi-step object use and imitation establish the existence of relative hierarchies of motor control. The retrieval errors in apraxia also support the notion of a hierarchical model for representing action in the brain. In this review, three functional brain imaging studies of action observation using the method of repetition suppression are used to identify a putative neural architecture that supports action understanding at the level of kinematics, object centered goals and ultimately, motor outcomes. These results, based on observation, may match a similar functional-anatomic hierarchy for action planning and execution. If this is true, then the findings support a functional-anatomic model that is distributed across a set of interconnected brain areas that are differentially recruited for different aspects of goal-oriented behavior, rather than a homogeneous mirror neuron system for organizing and understanding all behavior.     

Teachers’ burnout, depression, role ambiguity and conflict

The present study investigates issues associated with teachers’ burnout in primary education as related to depression and role conflict–ambiguity. At the time of the study the participants (562 teachers) were working in seventy nine (79) Primary Education State Schools in Greece (Athens and two prefectures in the southern part of the country). The results showed that of the three factors comprising the Burnout inventory (MBI, Maslach and Jackson, MBI: Maslach Burnout Inventory; manual research edition, 1986), (i.e., Emotional exhaustion, Personal accomplishment, Depersonalization) Emotional Exhaustion showed a statistically significant (positive) correlation with the factors that comprise: (a) the Scale of Depression (CES-D: Ensel, in: Lin et al. (eds.) Social support, life events and depression, 1986; Radloff, Applied Psychological Measurement 1: 385–401, 1977) such as Depressed affect, Somatic retarded activity and (b) Degree of Role Conflict (Role Conflict and Role Ambiguity Scale, Rizzo et al., Administrative Science Quarterly, 15:150–163, 1970, adapted in Greek by Koustelios and Kousteliou, Psychological Reports, 82:131–136, 1998); similarly, Positive affect (CES-D) and Degree of Role Clarity (Role Conflict and Role Ambiguity Scale) showed a statistically significant (negative) correlation with the same factor (Emotional exhaustion). Furthermore, a regression analysis performed with Personal accomplishment as the dependent variable showed that the (combined) factors of Role Ambiguity, Positive Affect and Somatic Retarded Activity contributed significantly to the prediction of the dependent variable; A third regression analysis performed with Depersonalization as dependent variable showed that Somatic Retarded Activity, Role Conflict, Positive Affect, Interpersonal Affect and Role Ambiguity contributed significantly to the prediction of this variable. Overall, the results showed that Greek teachers experience low-moderate levels of Burnout, Depression, Role conflict and Role ambiguity.     

Toward an Understanding of “The Sex Game”: The Effects of Gender and Self-Monitoring on Perceptions of Sexuality and Likability in Initial Interactions1

Results of several studies indicate that men attribute more sexual meaning to heterosexual interactions than do women. Based on Abbey's (1982) findings, we hypothesized that males, in comparison to females, would attribute more sexuality to opposite-sex partners. Based on findings from several self-monitoring dating studies, we predicted that high self-monitors would rate their partners and themselves higher on sexuality and likability traits than would low self-monitors. A laboratory study was conducted in which mixed-sex pairs of participants discussed their likes and dislikes about college life. Participants then rated themselves and their opposite-sex partners on a set of sexuality and likability trait adjectives and indicated their interest in getting to know their partner better. Results supported the gender hypotheses, whereas they only partially supported the self-monitoring predictions. The self-monitoring effects on self-ratings of sexuality and partner ratings of likability are used to explain why high self-monitors are more successful than low self-monitors in establishing heterosexual relationships.
