Cholinergic rebound after chlorpromazine exacerbates lithium muscarinic-induced limbic seizures in rats: implications for psychiatric treatment.

When lithium serum levels were within the (human) therapeutic range, young and old adult male and female rats (housed singly or in groups) all displayed faster limbic seizure onset times in response to a muscarinic cholinergic agonist (pilocarpine 20 mg/kg) if a single systemic dosage of chlorpromazine was injected 24 hours previously. The effect was comparable to injecting an additional 10 mg/kg of pilocarpine. These results strongly suggest that cholinergic rebound from chlorpromazine administrations during lithium treatment could facilitate subclinical electrical lability and very localized neuronal necrosis within the limbic system of clinical patients, resulting in normalization of psychiatric symptoms.     

Eyewitness testimony and memory distortion

Abstract: Do memories change as we acquire new information? Recent research on memory distortion using implicit tests along with research using confidence is reviewed and new studies are presented. Two new studies asked misinformed subjects to provide reasons for their answers. In each study 15% to 27% of subjects said they remembered seeing items they had only read about. In another study subjects were asked to identify the source of misleading items they had seen in slides or read in misleading questions. Subjects were more likely to say they had seen in slides something they read about in the questions than they were to confuse information from two nearly identical sets of slides. Recent work shows that, not only is it possible to distort memory for events, it is possible to implant an entire memory for something that never happened. The evidence is now clear that we can become mentally tricked into making large as well as small changes in the way we recall the past.     

Victim-Blaming and Society-Blaming Scales for Social Problems

Until now, no general scales have been available for measuring victim or society blaming. This constraint has been an impediment to policymaking with regard to those who are affected by social problems. Four scales were constructed: stable victim-blaming scale, unstable victim-blaming scale, stable society-blaming scale, and unstable society-blaming scale. Based on the results of the preliminary exploratory factor analysis and the reliability coefficients, the unstable society-blaming scale was deleted from further analysis. Then, a confirmatory factor analysis using the LISREL 7 program was conducted to evaluate the parameter estimates of the scale items and examine the construct validity of the 3 scales. The scales were judged to have construct validity with satisfactory reliability.     

Social Perceptions of Termination of Medical Treatment: Suicide or Rational Decision?

In two studies, college students read about a critically ill patient who died after CPR attempts failed, CPR was not attempted pursuant to a "Do-Not-Resuscitate" (DNR) order, he terminated all medical treatment, or he self-administered a lethal injection. Death resulting from treatment termination was perceived as significantly more unconventional than were death by CPR failure or DNR order. Ending treatment and lethal injection were perceived as equivalent acts of suicide, and resulted in the patient's being seen as less rational and less capable of making health care decisions. Timing of the patient's decisions regarding treatment, as indicated by the presence or absence of Living Will information, did not alter these perceptions. Results are discussed in light of opposing hypotheses regarding views of "naive" social perceivers toward actions with identical outcomes: that acts of commission are perceived as causal and rated more negatively than acts of omission (Spranca, Minsk, & Baron, 1991), and that acts seen as abnormal are attributed greater causal impact (Hilton & Slugoski, 1986).     

The Importance of Attitudes in the Prediction of College Students' Intentions to Drink

Fishbein's (1967, 1980) theory of reasoned action was used to test the relative importance of attitudes and subjective norms in predicting undergraduate students' intentions to perform 3 different types of social drinking actions: avoiding drinking, drinking enough to get a slight buzz, and drinking enough to get drunk. A multiple regression paradigm was used to determine the relative effectiveness of attitudes and subjective norms in predicting intentions to perform each of the 3 drinking behaviors. Although attitudes were consistently found to be better predictors of intentions than were subjective norms, the strength of the attitude-intention relation varied widely across the 3 actions. In particular, the attitude-intention correlation was strongest for "drinking enough to get drunk." Findings also suggest that subjective norms, previous behavior, and perceived behavioral control are not important variables for predicting this behavior.     

CHOICE-MAKING TREATMENT OF YOUNG CHILDREN'S SEVERE BEHAVIOR PROBLEMS

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement.     

Parental Smoking and the “Epidemic” Spread of Cigarette Smoking1

“Epidemic” models of transitions between stages of cigarette smoking describe the spread of smoking behavior through face-to-face encounters. An epidemic model was successfully fitted that allowed epidemic parameters to be conditioned on the smoking status of adolescents' parents. Model comparisons supported the conclusion that the transition from nonsmoker to trier involved social contacts, whereas the transition from trier to regular smoker was best modeled as a constant rate (i.e., did not depend on the population prevalence of smokers). The transition rate from nonsmoker to trier was more rapid in children of smoking parents than in children of nonsmoking parents. Adolescents with and without smoking parents did not differ in the rate of transition from trier to regular smoking.     

The Career Satisfaction of the Association for Counselor Education and Supervision Members

Members of the Association for Counselor Education and Supervision completed a questionnaire on career satisfaction. A majority reported being quite satisfied with their careers. Most experienced only occasional burnout, and over half perceived their career stress as no greater than moderate.
