Current aspects in the diagnosis and therapy of hypothyroidism]

Also at present hypothyroidism is frequently not recognised, especially its discrete forms of the course should be more included in differential-diagnostic considerations. Decisive is the clinical anamnestic suspicion which, after exhaustion of the laboratory-diagnostic possibilities, will justify the application of probatory therapy, even on a relatively large scale. This disease deserves secial regard, taking into consideration its beneficial and well practicable therapeutic influencibility and, on the other hand, its sever prognostic consequences to the subject in case of therapeutic neglect. The problems of therapy are not so much consisting in the occurrence of side-effects or in a non-optimal choice of drugs, but the more in a delayed onset, low dosage or interruption of the therapy.     

An investigation of late closure: The role of syntax, thematic structure, and pragmatics in initial interpretation.

Four reading-time experiments investigated the application of the late closure principle in Italian. The experiments tested the principle governing the initial attachment of different types of modifiers (relative clause, adjectival phrase, and prepositional phrase) to a complex noun phrase. By manipulating the type of preposition within the complex noun phrase, the authors investigated the role of the thematic structure in initial and final parsing. The results show that the late closure principle applies to initial parsing in Italian without being affected by the thematic structure of the complex noun phrase. Final interpretation, however, shows an effect of pragmatic preference and an effect of thematic structure on syntactic revisions. The results are discussed in terms of a parsing model that adopts syntactic parsing strategies and makes modular use of linguistic information.

"More on recognition and recall in amnesics": Correction to Hirst, Johnson, Phelps, and Volpe (1988).

Reports an error in "More on recognition and recall in amnesics" by William Hirst, Marcia K. Johnson, Elizabeth A. Phelps and Bruce T. Volpe (Journal of Experimental Psychology: Learning, Memory, and Cognition, 1988[Oct], Vol 14[4], 758-762). In this article, the authors failed to specify how the group of amnesics that they test in their article differed from the nonalcoholic amnesics tested in Hirst, Johnson, Kim, Phelps, Risse, and Volpe (1986). The pertinent statistics are given in the erratum. Additionally, in the last sentence on page 760, the degrees of freedom for the t test should be 8 instead of 10. (The following abstract of the original article appeared in record 1989-16104-001.) Hirst et al. (1986) reported that amnesic forced-choice recognition was relatively preserved when compared with amnesic recall. They equated normal recognition and amnesic recognition by extending exposure time for the amnesics and then comparing amnesic recall and normal recall. Amnesic recall was worse than normal recall, despite equated recognition. We conducted two experiments to extend that result. Experiment 1 established that the findings of Hirst et al. are not paradigm specific and hold when amnesic recognition and normal recognition are equated by increasing the retention interval for normals. In Experiment 2 we further established the generality of the result by examining yes-no recognition. Findings further specify the selective nature of the direct memory deficits in amnesics.

Models of Thin Film Growth Modes

This paper discusses the wetting of a crystalline substrate by a deposit, and the metastable and equilibrium configurations that can be expected to appear during the growth of a film. The stability of thin film structures is related to the dependence of the system free energy on the coverage. In the case where the uniform film is not the equilibrium state, the stability against small perturbations or cluster nucleation is considered, Other factors that influence the film structure and stability are the degree of misfit between the film and the substrate, and the surface roughening transition temperature of the film-vapor interface.     

Attitudes of academic clinical psychologists toward projective techniques: 1968–1983.

Replicated a survey by the 3rd author et al (see record 1968-18843-001) concerning the attitudes of academic clinical faculty toward projective techniques. The questionnaire was completed by 153 faculty in American Psychological Association (APA)-approved programs in clinical psychology. As was found in the 1968 survey, many Ss supported instruction in projectives, but they held generally negative attitudes toward projectives. More of the 1983 Ss than the 1968 Ss expressed negative attitudes toward specific projectives such as the Rorschach. Negative attitudes toward projectives were particularly prominent among the younger Ss in the 1983 survey. (14 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Retrieval failure in the presence of retrieval cues: A comparison of three age groups.

Cued recall of preteens, young adults, and senior adults (480 Ss) was compared under 7 conditions of practice. (Preteens were 11–12 yrs old; young adults were college students; senior adults had a mean age of 47.5 yrs.) The independent variable was the number of items in the list which began with the same letter of the alphabet; the number of items per alphabetic cue was 1, 2, 3, 4, 6, 8, or 12. The interaction between age and the number of items per cue was not significant, thus permitting the inference that retrieval failure due to the number of items per cue was invariant with age. This result is discussed in terms of cue overload, and the suggestion is offered that cue overload may result from information lost when memory traces carrying the same retrieval information interact and are recoded. Further analyses pursued the nature and locus of the items not recalled by preteens and senior adults, and the judgment is made that the retrieval failure in these 2 age groups, although comparable in quantity, is probably different in quality. Also reported is the finding that, under free-recall conditions, senior adults were able to recall as well as young adults, and this result was related to the greater opportunity for meaningful organization in free recall than in cued-alphabetic recall.

Quality of acquired responses to tastes by Rattus norvegicus depends on type of associated discomfort.

Conducted 3 experiments with 50 male Sprague-Dawley rats to examine whether Ss could learn different responses to tastes paired with different types of discomfort. Ss were trained to avoid a sugar solution through pairing with LiCl toxicosis (upper gastrointestinal tract discomfort), shock (peripheral pain), or high levels of lactose (lower gastrointestinal tract discomfort). Among Ss matched for strength of avoidance of the sugar solution, only the LiCl group showed orofacial responses indicative of distaste; the other groups continued to show positive orofacial responses to the sugar solution. These results, in conjunction with recent results on humans, are interpreted to represent a distinction between food rejection based primarily on unpalatability (distaste) and food rejection based primarily on anticipated negative consequences of ingestion (danger). Results also support the hypothesis that upper gastrointestinal distress (most probably nausea) plays a special role in negative palatability shifts (acquired distastes). These results have implications for the understanding of predispositions in learning and suggest important differences in the quality of different types of associations.

The effects of the COD:P ratio on laboratory activated sludge systems

Laboratory activated sludge systems were operated at various COD:P ratios to study the effects of the influent phosphorus concentration on COD removal efficiency, cellular phosphorus, carbohydrate and protein contents, and alkaline phosphatase activity. In varying the COD:P ratio, the COD was held constant at 1000 mg l⁻¹ and phosphorus concentrations of 1, 2, 3, 5, 7, 9, 10, 20, 35 and 50 mg l⁻¹ were used. The optimum COD:P ratio for this study was found to be 100:1. Increasing the phosphorus concentration in the influent above one percent of the influent COD did not provide for an increase in the COD removal nor for significant changes in the cellular protein and carbohydrate content or the alkaline phosphatase activity.     

An On-Chip Spectrum Analyzer for Analog Built-In Testing

This paper presents an analog built-in testing (BIT) architecture and its implementation. It enables the frequency response and harmonic distortion characterizations of an integrated device-under-test (DUT) through a digital off-chip interface. External analog instrumentation is avoided, reducing test time and cost. The proposed on-chip testing scheme uses a digital frequency synthesizer and a simple signal generator synchronized with a switched capacitor bandpass filter. A general methodology for the use of this structure in the functional verification of a DUT is also provided. The circuit-level design and experimental results of an integrated prototype in standard CMOS 0.5 m technology are presented to demonstrate the feasibility of the proposed BIT technique.Marcia G.

Source monitoring.

Aframework for understanding source monitoring and relevant empirical evidence is described, and several related phenomena are discussed: old–new recognition, indirect tests, eyewitness testimony, misattributed familiarity, cryptomnesia, and incorporation of fiction into fact. Disruptions in source monitoring (e.g., from confabulation, amnesia, and aging) and the brain regions that are involved are also considered, and source monitoring within a general memory architecture is discussed. It is argued that source monitoring is based on qualities of experience resulting from combinations of perceptual and reflective processes, usually requires relatively differentiated phenomenal experience, and involves attributions varying in deliberateness. These judgments evaluate information according to flexible criteria and are subject to error and disruption. Furthermore, diencephalic and temporal regions may play different roles in source monitoring than do frontal regions of the brain. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
