Message therapy: Language approach to stuttering therapy with children

Message therapy is a clinical procedure designed to be used as a carry-over technique with school-age stutterers or as a sole technique with the preschooler. The focus of therapy is on a unit of communication rather than on the moment or place of stuttering. One of the basic assumptions of the procedure is that the child is beginning to monitor how he/she is speaking rather than what is being communicated (i.e., the “message”)—each task requiring a different cognitive process. The emphasis of the therapy is to redirect the child's attention to “what he/she is saying.” The clinical procedures are discussed as they relate to the specific population.     

Effective functioning in dual-career families: an investigation

This study is concerned with the commonalities inherent in diverse psychotherapeutic strategies, despite seemingly discontinuous theoretical stances. Two approaches were evaluated with respect to effective family functioning, viz. Analytical Psychology and Systems Theory. Analytical Psychology posits the growth of conscious awareness in the individual as the source of therapeutic change. Problem centred systems therapy of the family emphasizes the importance of teaching clinically presenting families to negotiate collectively family rules and expectations and thus to allocate and monitor roles via clear and direct verbal communication. Both positions thus stress the reflective mode as a pivotal factor in effective problem solving. Analytical psychology maintains that conscious awareness expands to the extent that the individual integrates the contrasexual aspect of the personality, that is, the affective, expressive mode or 'feminine principle' in the male, or the instrumental, assertive 'masculine principle' in the female. Such individuals are said to be 'androgenous'. It was therefore hypothesized that such individuals would more readily be able to negotiate family rules and expectations in a manner consistent with a major therapeutic thrust of family therapy. These clinically derived hypotheses were subjected to an empirical test by assessing twenty, non-clinical, dual-career families where both parents pursued careers and were therefore presumably both required to share instrumental and affective roles on the basis of mutual agreement. Results indicated that negotiation contributed significantly to successful role fulfilment and effective family functioning, thus substantiating the focus of family therapy strategies upon clear and direct communication and role allocation.     

The role of the accessory and main olfactory systems in maternal behavior of the primiparous rat

The objective of this study was to analyze the respective roles of the main and accessory olfactory systems in the development of maternal behavior in the primiparous Wistar rat. Females underwent one of the following treatments: vomeronasal nerve section (VN), irrigation of nasal cavities with 5% ZnSO4 solution (ZN), surgical control, saline irrigation control, and normal control. Surgical or first irrigation were done before mating occurred. Irrigations were done every 7 days thereafter. The dams and their litters were observed from the day the litter was born (Day 1) through Day 16. Pup weights and temperatures were recorded daily. Home cages were checked daily for changes in nest location and number of times pups were found out of the nest. Retrieving tests were conducted on Days 4, 7, 10, and 13. The following behavioral items were observed: number of pup retrievals , number of times mother nosed or licked pups, percentage of litter returned to nest by end of test, dam self-grooming, dam climbing or rising, and dam digging or burrowing in shavings. The VN dams and their litters were not significantly different from the control dams and their litters on any of the measures taken. The ZN dams and their litters were not significantly different from their controls on all measures except for pup body temperature which was slightly lower from Day 13 through day 16 and pup body weight which was slightly lower from Day 12 through Day 16. Since these differences are very small, they do not seem to indicate a serious deficiency in maternal behavior. The results indicate that adequate maternal behavior develops with either of the two systems intact.     

Information processing abilities in twins reared apart

A battery of information processing measures and psychometric tests of specific and general cognitive abilities was administered to a sample of 105 individuals which included 34 monozygotic and 13 dizygotic reared apart twin pairs or triplets. Correlations between information processing parameters and psychometric abilities as well as twin resemblances for the information processing parameters were examined. In a principal components analysis of the information processing parameters, three components were identified which accounted for 67% of the total variation; Overall Speed of Response (OSR), Speed of Information Processing (SIP), and Speed of Spatial Processing (SSP). OSR was significantly correlated with WAIS IQ, and psychometric measures of verbal reasoning, spatial ability, and perceptual speed and accuracy. SIP was significantly correlated with WAIS IQ, measures of verbal reasoning, and one of the perceptual speed and accuracy measures. SSP was significantly correlated with measures of both spatial ability and perceptual speed and accuracy. Due to the small size of the dizygotic twin sample, no strong conclusions could be drawn regarding the magnitude of their resemblance. The correlation between component scores of reared apart monozygotic twins was significant for OSR, but not for SIP or SSP.     

Teachers do not Deal in Widgets

Although the use of merit pay, incentive pay, bonus pay, and job promotion are well-established measures in the private or corporate sector of American society, few examples of successful teacher merit pay systems exist. In 1983, the Eastern Washington University Department of Education surveyed six major private corporations to determine whether corporate merit pay programs could be applied to teachers and educational institutions. Survey findings suggest several reasons why merit pay programs for teachers will probably fail: (a) lack of monetary goals; (b) the necessity for subjective evaluation, which requires multiple measurement devices, extensive supervision, and time; (c) the absence of a many-tiered corporate structure in most educational institutions; and (d) increased supervisory direction that could stifle creativity and flexibility.     

Working memory theory of hippocampal function needs qualification

To compare the predictive value of "cognitive map" and "working memory" theories of hippocampal function, the performance of rats with dorsal hippocampal lesions was compared to that of control rats in a series of experiments. In Experiment I, experimental rats learned a spatial alternation task with normal ease, but in Experiment II, they were significantly impaired on an elevated 8-arm radial maze. In Experiment III, the performance of the same experimental and control rats was compared on two versions of a 16-arm enclosed radial maze. In the first version, carpet inserts served as cues to mark eight unbaited arms and each of the remaining arms contained one food pellet. While both experimental and control rats successfully avoided the set of cued arms, experimental rats reentered uncued baited arms more frequently than did control rats. In the second version no intramaze cues were provided, but the spatial distribution of baited and unbaited arms remained the same as that used in the first version. In this uncued version, experimental rats both entered unbaited arms and reentered baited arms more frequently than did control rats, i.e., they were impaired in both "reference" and "working" memory. These findings are compatible with the hypothesis that hippocampal lesions result in an impaired capacity to form cognitive maps but they are not compatible with the working memory hypothesis. Furthermore, twelve separate evaluators classed experimental rats as using fewer mapping and more orientation strategies than control rats in the 8-arm maze.     

Context effects in the behavioral ratings of hyperactivity

It was proposed that parents of hyperactive children would observe more problems at home in some but not all home contexts. To test this hypothesis, parents of teacher-identified hyperactive and nonhyperactive children were asked to complete a context-specific behavioral rating scale (Werry, 1968). Hyperactive children were rated by their parents as changing activities, talking, interrupting, and exhibiting dependency more than nonhyperactive children. Furthermore, those differences between hyperactive and control children were observed primarily in the play and homework contexts.This research was supported by a National Institute of Mental Health Grant MH(32282).     

Evidence for the involvement of brain GABA and serotonin systems in the anticonflict effects of chlordiazepoxide in rats

Using male hooded Lister rats the effects of GABAergic and serotonergic treatments alone and with chlordiazepoxide (CDP) were compared with the behavioral effects of CDP in a conditioned conflict procedure with three components; Reward, Time Out, and Conflict. CDP (2.5, 5.0, and 10.0 mg/kg ip) dose- relatedly increased punished and time out responding, but increased rewarded responding in an inversely dose-related manner. Punished responding was enhanced by chronic treatment to a rate which remained stable between 9 and 19 injections. The GABA transaminase inhibitor ethanolamine-O-sulfate (EOS), given chronically in drinking water (5.0 mg/ml), increased punished responding linearly to a high stable level after 2-3 weeks. Rewarded and time out responding were less substantially increased. CDP given with EOS dose- relatedly increased time out and punished responding substantially above the rates found with either treatment alone. The GABA antagonist picrotoxin blocked the increase in punished and time out responding found with EOS and CDP alone. The tryptophan hydroxylase inhibitor p-chlorophenylalanine (PCPA; 100 mg/kg x 3) linearly increased punished responding for the first week of treatment. CDP with PCPA selectively and significantly increased punished responding above the rates for either treatment alone, but the increases were not as substantial as those with EOS + CDP. The serotonin reuptake inhibitor Wy 25093 reduced increases in time out and punished responding under CDP, and the precursor 5-hydroxytryptophan (5-HTP) counteracted increases in punished responding under PCPA but also substantially reduced rewarded responding. These results provide evidence that both increased GABA and decreased serotonin transmission are involved in the anticonflict effects of CDP, as EOS and PCPA both mimicked and potentiated effects of CDP, while picrotoxin, Wy 25093, and 5-HTP counteracted them.(ABSTRACT TRUNCATED AT 250 WORDS)     

Residential-maze behavior of spontaneously hypertensive rats

Spontaneously hypertensive rats (SHR) exhibit elevated levels of ambulation after transfer to a novel environment compared to the Wistar-Kyoto rat (NR). The present experiment compared long-term activity of SHR and NR in a residential maze to determine whether the SHR exhibit elevated levels of locomotor activity under undisturbed, baseline conditions in addition to enhanced reactivity to stimuli. The SHR were much more active visiting more arms of the maze than the NR during the initial hours following transfer to the maze, and during hours around dark onset and light onset. However, the SHR also exhibited higher levels of activity than the NR under baseline conditions. While the NR visited the arm containing food more frequently than other arms, the SHR exhibited no such preference. These data show that both stimulus-induced and basal levels of ambulation are increased in the SHR compared to its normotensive genetical counterpart.
