Effect of anosmia on the behavior of standard non-aggressive male mice opponents during agonistic encounters

This study assessed whether the differences observed in a previous experiment [Martinez M, Salvador A, Simon VM (1994): Aggressive Behavior 20:441–451] in the behavior of isolated male mice over several agonistic encounters in which they confronted either an “anosmic” or an “intact” non-aggressive “standard opponent” were due to the differences in the behavior of the opponents themselves. Ethologically-inspired analysis was used to assess the behavior of the opponents during the first agonistic encounter. Anosmic opponents spent less time in social investigation and defense and more time in immobility than intact ones. These results suggest that the differences in the behavior of the opponents could be one of the causes of the differences observed in the behavior of the aggressive males confronting them. However, more research is needed to study if other variables, such as the production of odors, are also affected by the state (deprived or intact) of the olfactory sense. These findings provide additional support for the view that the type of opponent used in studies on intermale aggression is of paramount importance.Aggr.

Longitudinal models of developmental dynamics between reading and cognition from childhood to adolescence

The authors applied linear dynamic models to longitudinal data to examine the dynamics of reading and cognition from 1st to 12th grade. They used longitudinal data (N=445) from the Connecticut Longitudinal Study (S. E. Shaywitz, B. A. Shaywitz, J. M. Fletcher, & M. D. Escobar, 1990) to map the dynamic interrelations of various scales of the Wechsler Intelligence Scales for Children--Revised (i.e., Full, Performance, and Verbal) and specific markers of the Woodcock-Johnson Psycho-Educational Battery--Revised reading cluster (i.e., Letter-Word ID, Decoding, and Comprehension). The results of these analyses indicate that (a) there is a positive dynamic relation between reading and cognition across the selected age range; (b) this dynamic relation is symbiotic, with positive influences in both directions; (c) the influence from cognition to reading is stronger when considering the Wechsler Intelligence Scales for Children Performance--Revised Performance scale and weaker with the Verbal scale; (d) when examining the different Reading subtests, the influences from cognition are more apparent for Letter-Word ID and Comprehension and are less perceptible for Decoding; and (e) the dynamics of reading and cognition appear to be of stronger magnitude during 1st to 3rd grade, less strong during 4th to 8th grade, and weaker from 9th to 12th grade.     

Mononormativity,Polypride, and the “Mono–Poly Wars”

Both in everyday life and scholarly discourse, monogamists and polyamorists tend to unfavorably portray one another as somehow flawed, misguided, or, in a word, “inferior.” This article documents and critically examines two pairs of interlocked psychosocial attitudes—monopride/polyphobia and polypride/monophobia—mediating this predicament of mutual competition in the context of Western mononormative culture. The ideological nature of these “mono–poly wars” is demonstrated through a brief review of empirical literature on the psychological health and relationship quality of monogamous and polyamorous individuals and couples. The article concludes by outlining a critical pluralist approach that eschews universalizing hierarchies between monogamy and polyamory, and provides tools for making qualitative distinctions within and among relational styles.     

An Idiographic Approach to Estimating Models of Dyadic Interactions with Differential Equations

We present an idiographic approach to modeling dyadic interactions using differential equations. Using data representing daily affect ratings from romantic relationships, we examined several models conceptualizing different types of dyadic interactions. We fitted each model to each of the dyads and the resulting AICc values were used to classify the most likely configuration of interaction for each dyad. Additionally, the AICc from the different models were used in parameter averaging across models. Averaged parameters were used in models involving predictors of relationship dynamics, as indexed by these parameters, as well as models wherein the parameters predicted distal outcomes of the dyads such as relationship satisfaction and status. Results indicated that, within our sample, the most likely interaction style was that of independence, without evidence of emotional interrelations between the two individuals in the couple. Attachment-related avoidance and anxiety showed significant relations with model parameters, such that ideal levels of affect for males were negatively influenced by higher levels of avoidance from their partner while their own levels of anxiety had positive effects on their levels of dyadic coregulation. For females coregulation was negatively influenced by both time in the relationship and their partner’s level of avoidance. Analysis involving distal outcomes showed modest influences from the individual’s level of ideal affect.     

Feelings of vulnerability in response to threatening messages: Effects of self-affirmation

We examined effects of self-affirmation on feelings of vulnerability and behavioral intentions following exposure to personally threatening messages varying in message strength. In Experiment 1, female alcohol consumers read a strong message linking alcohol to breast cancer risk. Self-affirmed participants exhibited higher feelings of vulnerability concerning consumption levels and personal risk. In Experiment 2, female caffeine consumers read a weak or strong message linking caffeine to breast disease. Self-affirmed participants reported greater feelings of vulnerability to breast disease and greater intentions to reduce caffeine consumption (relative to control participants) only when reading the strong message. Effects on intentions were mediated by effects on feelings of vulnerability. These studies show that feelings of vulnerability can mediate effects of self-affirmation on intentions to change behavior under threat, although only in the presence of strong messages.     

Table talk: inviting students to share the feast

This account describes part of the first morning of the AFT accredited South Yorkshire Foundation Course in Family Therapy and Systemic Practice. The course committee members join together in a reflective conversation about the course. We share with the students our ‘kitchen table’ discussions, the history of our involvement, and how it has affected our lives. We aim to introduce social constructionist practice in which we present the context of the course and address the power relationships in the room by being transparent about our own experiences. We hope to create an atmosphere in which learning can flourish.
