Evaluation and elimination of an avoidance response in a child who stutters: A case study

In this case study, efforts to treat stuttering in a 6-year-old male with cerebral palsy were complicated by frequent replies of “I don't know” that allowed the child to avoid more extensive answers to conversational questions. Following a program of extinction plus differential reinforcement of alternative behavior (DRA), the response “I don't know” was decreased while both speech rate and stuttering increased. Simplified habit reversal (SHR) techniques (controlled breathing) were then applied and resulted in a reduction of stuttering and maintenance of low rates of avoidance. A reversal to baseline resulted in initially high levels of avoidance and low levels of stuttering, with these trends reversing as baseline continued. The SHR treatment for stuttering was then reimplemented and stuttering rates again decreased while avoidance rates remained low, Implications are discussed.     

Paradigms lost: Remembering herstories and other invalid subjects

During the First World Family Therapy Congress, Dublin, 1989, the author was the only women on a six member panel discussing The New Paradigm. This article re-presents her attempt to remember women and other invalid subjects, (e.g. those in poverty) in what was imagined would be an otherwise male oriented discourse. Until recently, within family therapy, the contrary and negatory experiences of women in families and society gained little recognition. This article joins others in adding herstory to history.She is in private practice at Vico Consultation Centre.The author acknowledges her team, Nollaig Byrne and Philip Kearney; and her sister witches (The Women in Therapy Chapter), Kay Gilliland, Bernadette O'Sullivan, Mia Van Doorslaer, and Jane Williams for their valued help and comments on this paper.     

Short-term early exposure to pups alters infanticide in adulthood in male but not in female wild house mice (Mus domesticus)

Male and female wild house mice (Mus domesticus) were allowed to remain in the cage of their parents until 30-35 days of age. When a second litter was delivered, the first litter was exposed to the younger pups for 2-10 days. In adulthood the male and female mice that had been exposed to pups as juveniles and an additional group that had cohabitated with their parents for the same length of time but were not exposed to pups were tested for infanticidal behavior. The frequency of infanticide by the adult female mice was not significantly different (55% vs. 70%, respectively). In contrast, the adult males that were exposed to pups as juveniles were significantly less likely to kill young in adulthood when compared with males that were not similarly exposed (35% vs. 80%, respectively). These data further demonstrate the strong influence of experience on the expression of infanticide by male mice and its relative unimportance to the expression of female infanticide.     

Specificity of learning in reality-orientation sessions: a single-case study

A single-case study of retraining of verbal orientation in a 68-year-old patient with Korsa-koff's psychosis is described. In order to test the specificity of learning three different lists of verbalorientation items were taught in separate phases of a multiple-baseline design. Learning did occur mainly in the appropriate phases, with little generalization across phases being apparent. The results support the presence of a relearning component in the Reality-Orientation approach. In addition they emphasize that it is desirable for treatment programmes to focus on particular target areas of functioning.     

Learned helplessness and “fear of success” in college women

Anagram performance in comparison and noncomparison situations of 90 high, medium, or low fear-of-success (FOS) women was examined after these subjects had experienced conditions within the traditional triadic learned helplessness design. Low FOS women in the comparison condition proved significantly more susceptible to learned helplessness effects than high FOS women on one dependent measure (number of incorrect anagrams), though not on the other (response latency). Results are discussed with reference to the FOS construct and to Zuckerman and Allison's (1976) scale, used in the present study. An argument is made for increased attention to personality variables within the learned helplessness paradigm.     

Fixed-ratio escape and avoidance-escape from naloxone in morphine-dependent monkeys: effects of naloxone dose and morphine pretreatment.

Lever pressing by rhesus monkeys was maintained by morphine injections during four equally spaced sessions each day. During other periods, lever pressing was maintained by timeout from a continuous naloxone infusion (escape), or by timeout from a stimulus that preceded naloxone injections, or termination of the injections (avoidance-escape). As naloxone dose increased in the escape procedure, response rate increased to a maximum and then decreased. In the avoidance-escape procedure, response rate generally increased as naloxone dose increased, but the changes in rate were small compared to the excape procedure. Substitution of saline for naloxone in the escape procedure led to a very low response rates within three sessions. In the avoidance-escape procedure, rate decrements produced by saline substitution appeared to be related to the behavioral history of the monkey. Previous escape experience led to more rapid decreases in responding when saline was introduced, whereas responding was maintained for 15 sessions in a monkey without prior escape conditioning. Morphine pretreatment produced comparable, dose-dependent decreases in response rates in both procedures. The rate-decreasing effects of morphine were exacerbated when no naloxone was delivered in the escape procedure.     

Group shift to caution at the race track

Group and individual riskiness were compared on $2 “win” best at the race track. Using the standard pretest-posttest risk-shift design, group discussion to unanimous decision was found to produce a cautious shift in group bets.
