In this paper we describe our newly constructed Constraining and Enabling Coding System (CECS). This scheme was constructed to identify family interactions that are conceptually relevant to adolescent ego development. First, we discuss the theoretical rationale and reliability properties of the codes. We then present results of applying the scales to(More)
Rapid eye movement (REM) sleep mechanisms may play a role in the pathophysiology of schizophrenia, but results have been inconclusive and studies of sleep in schizophrena have been deficient in identifying, comparing, and differentiating between subcategories of schizophrenia. Twenty-nine hospitalized, drug-free schizophrenics were divided into three(More)
The authors conducted a study of 18 depressed patients to see whether EEG sleep measurements might provide a predictive tool for response to antidepressant medication. They found that although the sedative characteristics of amitriptyline did not differentiate good responders from poor responders until the third week of drug treatment, the good responders(More)
The importance of emotion to group outcomes in FtF highlights the need to understand emotion contagion in distributed groups. The present study examines the transfer of negative emotion in online groups. Negative emotion was induced in one of three group members completing a task in CMC. The data suggest that emotion contagion took place at the group level,(More)
The similarities in structure and usage of two widely used adjective checklists, the Profile of Mood States (POMS) and Symptom Checklist (SCL), suggested the feasibility of pooling the items from the two scales into a single factor analysis. This procedure was clinically appealing, statistically sound, and provided an efficient method to reduce and refine(More)
Honeybees use their visual flow field to measure flight distance. It has been suggested that the experience of serial landmarks encountered on the flight toward a feeding place contributes to distance estimation. Here, we address this question by tracing the flight paths of individual bees with a harmonic radar system. Bees were trained along an array of(More)
In a multicenter, placebo-controlled, clinical trial, the efficacy of Limbitrol was compared with that of its components, amitriptyline and chlordiazepoxide. All patients had a diagnosis of primary depression. Data from 279 patients were evaluated using the Hamilton depression scale, the Beck depression inventory, and physician and patient global change(More)
Efficient auditory processing is hypothesized to support language and literacy development. However, behavioral tasks used to assess this hypothesis need to be robust to non-auditory specific individual differences. This study compared frequency discrimination abilities in a heterogeneous sample of adults using two different psychoacoustic task designs,(More)
A number of modes of oscillations of particles and fields can exist in space plasmas. Since the early 1970s, space missions have observed noise-like plasma waves near the geomagnetic equator known as 'equatorial noise'. Several theories were suggested, but clear observational evidence supported by realistic modelling has not been provided. Here we report on(More)
