An unlabeled bracketing solution to the problem of conjoined phrases in Montague's PTQ

Conclusions Although Montague claims that the system of The proper treatment of quantification in ordinary English includes some conjunction and disjunction, the rules for other grammatical constructions do not take conjunction or disjunction into account, and in general fail either syntactically or semantically when one of their arguments is so formed. Using an unlabeled bracketing of syntactic structure and recursive definitions, we have been able to rewrite the rules so that correct results are obtained.These results should provide a firmer basis for extension of PTQ.This research was supported in part by NSF Grants GS-31309 and BNS 76-23840. Our observations were made with the aid of several computer programs for PTQ: a sentence generator for the bracketed syntax, a parser, and a translator. I should like to thank Philip Tedeschi, David Warren, and David Lewis for helpful discussions. Warren is also acknowledged as co-author of the section on the semantic role of conjunction.     

The Primary Mental Health Project (PMHP): Evaluation of current program effectiveness

This study evaluated the effectiveness of the Primary Mental Project (PMHP), a program for early detection and prevention of school adjustment problems. Pre- and postprogram assessments were done with 215 primary-grade children seen in PMHP, usig teacher ratings of problem behaviors and competencies, and child-aide ratings of problems. School mental health professionals judged educational and behavioral changes in project children during the year. Significant across-the board improvements were found on all criterion measures. Modest intercorrelations among criterion change estimates suggested that the observed changes were due to program, rather than halo, effects. PMHP children also improved significantly more than matched, retrospective controls.     

Coping With Stress: Getting the Message Across

On a campus of 30,000 students there are many who will not have direct contact with the Personal Counseling Service; yet those students experience and must cope with numerous pressures, which may affect their personal lives and academic progress. To help these students become more aware of stress areas and coping skills we submitted an article to The Addition, the Division of Student Services' semester newspaper. The unusual format for the information was selected to be eye-catching and thus more likely to be read than a regular news-format article.     

A machine-level software program for the generation of aversive conditioning schedules using the KIM-1 microprocessor

A microprocessor system can be used both to control aversive conditioning (classical, signaled and Sidman avoidance, and conflict) experiments and to acquire behavioral data in multiple subjects at a fraction of the cost of solid state systems. The software described in this paper can be used to program tones and shocks and count responses, independently, in up to 12 animals simultaneously.     

THE GENERALIZATION EFFECTS OF PARENT TRAINING ACROSS STIMULUS SETTINGS

Five parents of nonverbal children were trained in two home settings to modify antecedents and consequences to their children's vocalizations. Generalization effects of the parent training on both the parent's and children's behaviors under different stimulus conditions were investigated using multiple-baseline designs. Increases in parent prompting and reinforcing their children's vocalizations generalized only minimally to a new setting in the home where parent training had not occurred. Child increases in vocalizations produced by the parents in the training settings did generalize to this new setting in the home. There was minimal generalization of child vocalizations to a free-play setting at school. In a formal speech session conducted by a behavior specialist at school, only one child showed definite increases in acquisition rate as a function of the parents starting to train the sound at home.     

Grouping strategies, peer influence, and free time as classroom management techniques with first- and third-grade children

This study systematically investigated the effects of different procedures on classroom behaviors ranging from teacher designated seating groups and seating groups based on sociometric data to peer encouragement and free time reinforcers. Subjects were first- and third-grade children in classrooms using a Follow Through program model. Data were taken on the attending behavior of the children in small groups arranged by the teacher. The level of appropriate attending behavior was low and did not increase when the groups were restructured based on sociometric data. The introduction of instructions to the peer groups to help the child with his or her work brought about a major increase in the third-grade subjects' appropriate behavior. Appropriate attending behavior for the first-grade children did not increase to the predetermined acceptable level until a free time period for each peer group was made contingent upon the appropriate behavior of the subject in each group. Frequencies of verbal interactions suggested peer attention has an effect on the appropriateness of peer interactions.     

Predicting Persistence of Nonsuicidal Self‐Injury in Suicidal Adolescents

Prospective predictors of persistent nonsuicidal self‐injury (NSSI) were examined in adolescents admitted to an inpatient psychiatric unit for suicidal behaviors and followed naturalistically for 6 months. Seventy‐one (77%) participants reported NSSI at baseline, and 40 (56%) persisted at the 6 month follow‐up. Those who endorsed automatic positive reinforcement (APR) as the predominant reason for NSSI were more likely to persist in NSSI. Depression over follow‐up, but not at baseline, also predicted persistence. These results suggest that helping high‐risk adolescents to identify alternative ways of generating emotion(s) to counter the effects of APR that may accompany NSSI should be a high priority treatment target.     

I Can Stomach That! Fearlessness About Death Predicts Attenuated Facial Electromyography Activity in Response to Death‐Related Images

Objective measures of suicide risk can convey life‐saving information to clinicians, but few such measures exist. This study examined an objective measure of fearlessness about death (FAD), testing whether FAD relates to self‐reported and physiological aversion to death. Females (n = 87) reported FAD and disgust sensitivity, and facial electromyography was used to measure physiological facial responses consistent with disgust while viewing death‐related images. FAD predicted attenuated expression of physiological death aversion, even when controlling for self‐reported death‐related disgust sensitivity. Diminished physiological aversion to death‐related stimuli holds promise as an objective measure of FAD and suicide risk.
