Effects of training students to identify the semantic base of prose materials

Feedback and feedback plus points toward a course grade were applied to the attentional behaviors (defined as the ability to identify the semantic base of text passages) of 30 undergraduate students participating in a reading comprehension development program. Correct underlining was increased, extraneous underlining was decreased, and postreading comprehension test scores improved as a result of the procedures. Scores on a standardized test of reading comprehension also increased significantly.     

Beauty Is Only "Name" Deep: The Effect of First-Name On Ratings of Physical Attraction

College students ( n = 197) voted to select a beauty queen from among six photographs equivalent in physical attractiveness, as determined by rankings of 35 students from a separate university. Half the photographs bore a desirable first-name and half were assigned an undesirable first-name. As predicted, firstname had a significant effect on physical attraction: Girls with desirable firstnames received 158 votes to 39 for those with undesirable names. These data were discussed in terms of an additive, rather than an interactive, effect, due to the nature of the task. The strength of these findings was related to the study's ecological validity.     

Planning: Theoretical considerations and empirical evidence

Summary A study of processes rather than of abilities characterizes much of Luria's work on cognitive functions. The three major functional organizations in terms of cognitive functions are: arousal, coding, and planning. Each of these has been described with a special emphasis on planning. Tasks appropriate for demonstrating the processes of planning are discussed and the emergence of a planning factor through factor analytic work has been described. Considerations relating to the independence of planning and coding processes in the context of normal and abnormal development are presented next. Finally, planful behavior as an integral part of purposive behavior in humans is considered in the context of consciousness.     

Interviewee perceptions of an organisational careers guidance scheme

A study was carried out during the early stages of the introduction of a career development scheme in a large government department. Information relating to aspects of various careers counselling issues was gathered from staff who had received such counselling and from personnel staff responsible for its provision. The study shows, amongst other things, that the interviewers were perceived to use some counselling skills, that the interviewers claimed they experienced few problems of role conflict, but that the staff tended to identify the interviewers with management. The findings are discussed relation to the appropriateness of interviewing style and to the broader context of how individuals might influence their career development within the opportunities provided by the organisation.     

Effects of stress and retesting on role play tests of social skill

The purpose of this study was to examine the role of stress in performance on role play tests of social skill. Chronic psychiatric patients were tested in a formal videotape studio or in an informal consulting room setting. Motoric and physiological measures were secured. In addition, one-half of the subjects were retested one week later. In contrast to previous studies, results indicated that the assessment was not stressful. The two groups were not different on any measure, and the mean heart rates ranged from only 80 to 84 b.p.m. The effects of retesting were difficult to interpret. There were reductions in motoric indices of anxiety (speech disruptions) but not on physiological indices. Overall, testretest reliability was quite high. The results raise several questions which affect interpretation of many social skills studies in the literature.     

Suprathreshold binocular interactions for grating patterns

Binocular interactions of suprathreshold grating patterns have been investigated using a reaction time measure of contrast detection. Simple reaction times were determined for monocular and binocular viewing conditions over a contrast range from .63 to near threshold. The results from all subjects showed binocular summation for contrast levels near threshold, but there was considerable variation across subjects for contrast levels above threshold. Some subjects showed summation over the entire contrast range, but other subjects showed either binocular inhibition or binocular facilitation for some range of contrast levels. The pattern of binocular interaction for a given subject was consistent for several spatial frequencies. The differences in types of interaction between subjects, the variation in magnitude of binocular interaction with contrast level for each subject, and the data from experiments involving stimulation of noncorresponding retinal areas show that the binocular interactions found for suprathreshold stimuli cannot be accounted for on the basis of probability, and must, therefore, result from physiological interactions between the two eyes. These interactions have been investigated further under conditions of (1) induced fixation disparity, (2) horizontal gratings, and (3) orthogonally oriented gratings.     

On knowing the meaning of words we are unable to report confirmation of a guessing explanation

This experiment investigated Allport's (1977) claim that normal subjects can be induced to make semantic errors of the type characterised by “deep dyslexia”. The procedure followed that used by Allport except that a subject based control for the chance level of semantic errors was included. The results replicated the original finding by producing a semantic error rate of 12·7%. It was shown, however, that this rate was not significantly higher than the calculated chance rate of 11·5%. It was concluded, therefore, that the semantic error rates reported by Allport can be accounted for in terms of a guessing artefact and thus they bear no relevance to the problem of deep dyslexia.     

Interaction of genetics and separation in canine hyperkinesis and in differential responses to amphetamine

A model of childhood hyperkinesis, using the Telomian-beagle hybrid dog, is described, demonstrating the interactions of genetics and separation in the development of this syndrome and in the favorable responses of some of these dogs to amphetamine. This work represents the collaboration of three laboratories, utilizing chiefly methods of inhibitory training. Inducing separation distress enhanced the resistance to inhibitory training and the favorable responses to amphetamine.     

A method for the analysis of complex avian song repertoires

A new method for the analysis of complex avian song repertoires is introduced. The method consists of sending a tape-recorded bird-song signal through five narrow band-pass filters and then to a five-channel high-speed pen recorder. A coding method that allows a researcher to convert the output from the pen recorder to numbers for later analysis by computer is described.
