Effectiveness of a Media Campaign to Reduce

This article describes the evaluation of a 4-1/2-month multimedia traffic-safety campaign that targeted young drivers in northeastern Tennessee. Discussion groups with teenagers provided the basis for public-service announcements (TV, radio, and billboard), which were developed specifically for this intervention. To determine the impact on crash frequencies among drivers 16–19 years old, baseline, intervention, and follow-up crash data were obtained from statistics maintained by the state. A time-series analysis of these data indicated that during the intervention period, there was a 21.6% decrease in crashes for which 16–19-year-old drivers were at fault, whereas a control location in southeastern Tennessee exhibited no significant change.     

Mental Health in the Schools

Progress is being made in the area of delivering mental health services in the schools through collaborative programs that involve combinations of schools, communities, and research-based programs. The goal of extending collaborative efforts to initiatives that prevent emotional and behavioral problems from developing or escalating is a cross-cutting theme of the National Agenda for Achieving Better Results for Children and Youth with Serious Emotional Disturbance. I discuss examples of collaborative efforts to prevent emotional behavioral problems in school children and ways by which this effort can be enhanced in schools and communities.     

Exogenous testosterone and social experience each enhance the development of aggressive behavior in Cyprinodon variegatus

The combined effects of testosterone and social experience from the time of hatching on development of aggressive behaviors in Cyprinodon variegatus were investigated. Social experience was defined as a rearing condition allowing visual, tactile, chemosensory, and auditory contact with zero, three, or 15 additional conspecifics. Behaviors were videotaped once weekly from 3 weeks to 4 months post-hatching, using the focal animal method, and an ethogram was constructed. At 3 months post-hatching, half the fish were injected once with testosterone propionate (2 μg/g b. w., i. p., vehicle-Ringer's solution) and the other half were injected with Ringer's isotonic saline solution. Testosteronetreated subjects showed significantly greater frequencies and durations of behaviors that may be related to aggression than did saline controls. Two weeks after the treatments, a round-robin tournament was conducted between testosterone- and saline-treated fish from each rearing condition. Testosterone-treated fish won significantly more encounters than did saline-treated subjects over all rearing conditions. Furthermore, significantly more aggressive acts were displayed by fish raised in the groups of 16 and the groups of four than did the Isolates. Although the number of aggressive acts exhibited by the group of 16 was greater than the group of four, the difference was not statistically significant.     

Explanatory style and cell-mediated immunity in elderly men and women

Correlated pessimistic explanatory style--the belief that negative events are caused by internal, stable, and global factors--with lowered immunocompetence in a sample of 26 older adults. Two measures of cell-mediated immunity--T-helper cell/T-suppressor cell ratio and T-lymphocyte response to mitogen challenge--were lower in individuals with a pessimistic style, controlling for the influence of current health, depression, medication, recent weight change, sleep, and alcohol use. A relative increase in the percentage of T-suppressor cells seemed to underlie this immunosuppression. Although the mechanism by which explanatory style might influence immune function remains unknown, we speculate that a pessimistic style might be an important psychological risk factor--at least among older people--in the early course of certain immune-mediated diseases.     

A simple procedure for accurately manipulating face-voice synchrony when dubbing speech onto videotape

A system is described involving an audio-video tape recorder, a control device, and a delay timer that dubs speech sounds onto prerecorded lip movements on videotape. Accuracy of synchrony or measured asynchrony between the sound and lip movements is a few milliseconds.     

Inhibitory associations contribute to perceptual learning in humans

Perceptual learning in humans was examined in 2 experiments. In Experiment 1, participants received intermixed exposure to 2 similar compounds (AX, BX, AX, BX, . . .) and blocked exposure to a 2nd pair of similar compounds (CY, CY, . . . , DY, DY, . . .). Aversions established to AX and CY generalized less to BX than to DY. In Experiment 2, 1 pair of compounds was presented in a forward order (i.e., AX3BX), whereas the 2nd pair of compounds was presented in a backward order (i.e., DY-->CY). Aversions established to AX and CY generalized less to BX than to DY. These results indicate that inhibitory associations contribute to perceptual learning in humans and thereby establish a fundamental similarity between the mechanisms that underlie perceptual learning in humans and rats.     

Co-constructed narratives around being “sick”: A minimalist model

The amount of physical damage may have no fixed relation to how much and in what ways a patient's life is disrupted. The authors discuss a model which addresses the bio-psycho-social complexity of a patient's illness and the narrative constructions which the patient, family members, and health care professionals influence to co-create the patient's identification with being sick. This minimalist model invites the reader to consider a variety of interrelated variable lenses through which to view the narratives around a patient's illness. Clinical case examples are used to illustrate the dominant story themes.     

Witnessing stories: Definitional Ceremonies in Narrative Therapy with adults who stutter

BackgroundNarrative therapy (White & Epston, 1990) was developed as an approach to counselling, as a response to the power relations that influence people's lives. Its use with people who stutter has been documented. A basic tenet of narrative therapy is that the dominant problem-saturated narrative is challenged by externalizing the problem, in due course facilitating development of an alternative narrative. Within this process, the definitional ceremony involving outsider witnesses is a key procedure used to influence change.AimsThis paper describes definitional ceremonies, and their application within a narrative approach to therapy for stuttering. The analysis of a specific definitional ceremony is presented, leading to an exploration of identity as a public and social achievement.MethodsA definitional ceremony involving a woman who stutters and family members was recorded and analysed using two methods: interpretative phenomenological analysis and Heideggerian hermeneutic phenomenological analysis. Details of the clinical application of definitional ceremonies with this client are described.Results and conclusionsResults from both methods of analysis were found to be similar. Notable results include the fact that the stuttering per se was not presented as the problem; rather, the impact of stuttering, especially the experience of bullying, was a dominant theme. This paper shows how definitional ceremonies can open opportunities for clients to present themselves in a preferred way, forming the basis for a new story and revised identity. Emerging themes can be identified for reflection and discussion with the client for therapeutic benefit.Educational objectives: (1) to describe and explain to readers the process of narrative therapy, with special attention to the use of definitional ceremonies; (2) to provide detail regarding the clinical processes involved with a specific definitional ceremony with one client; (3) to have the reader appreciate the specific importance of involving outsider witnesses in the therapy process; (4) to discuss the outcomes of the use of this particular definitional ceremony.
