Improving visual acuity in a myopic child: Assessing compliance and effectiveness

Improvements in visual acuity following vision training were evaluated for an 11$\text{1}\text{2}$-yr-old myopic male. Initial increases in the distance at which the S could discriminate letters were found. However, performance began to deteriorate as training progressed. A negative-reinforcement procedure was employed in order to rule out motivational factors potentially related to this decreased performance. Using a changing criterion within an ABCBC reversal design, the distance at which the S correctly discriminated letters increased by more than $\text{4}\text{1}\text{2}$ times and was clearly related to the reinforcement procedure.     

Instrumental conditioning of scratching in the laboratory rat

Experiment 1 demonstrates that scratching in the laboratory rat can be instrumentally conditioned with food reinforcement. However, the asymptotic rate of performance of this response is shown to be low, as compared with an instrumental lever press response. It is suggested that one reason for this low rate of responding is that the scratch response can only be performed in the presence of an infrequently occurring itch stimulus. In support of this account the remaining experiments demonstrate that the rate of instrumental scratching can be increased relative to that shown by control groups by using a technique which might be supposed to increase the frequency at which an itch stimulus occurs.     

Autonomic learning

Academic achievement was resolved into its intellectual and motivational components. IQ, personality variables, and parameters of operant and classical conditioning of autonomic nervous system controlled variables were examined in 99 black inner-city high school seniors. Six physiological variables(respiration, heart rate, finger plethysmogram, frontalis muscle potential, palmar skin conductance, and palmar skin potential) were analyzed by computer using analog-to-digital conversion and a Points of Interest (PI) program. Psychological measures were full WAIS IQ, Edwards Personality Inventory(EPI), Cattell Sixteen Personality Factor Questionnaire(16PF), McClelland need Achievement test(n Ach), Object Sorting test, Minnesota Counseling Inventory(MCI), Level of Aspiration Board, and Rotter—Miller Locus of Control. Achievement(Ach) was defined as the residuals of total grade point average(GPA) regressed on IQ. Each of 19 variables which discriminated significantly between high and low achievers was employed in step-wise regression analyses for GPA and Ach separately. In a regression analysis of variance of GPA, IQ=20.44%, EPI=9.08%, and physiological measures =21.37%(operant conditioning =18.70%; classical conditioning =2.67%). Combined measures of motivation(psychological and physiological) =30.45% of the variance in GPA. The entire psychological and physiological test battery, including IQ, contributed a total of 50.89% of the variance in GPA. In a regression analysis of variance in achievement, psychological measures, other than IQ(six EPI and one 16PF), =11.0% and physiological measures =30.3%. As a replication, this study demonstrated significant correlation between autonomic conditioning and school achievement.     

Philosophical conceptions of rationality and psychiatric notions of competency

Psychiatrists are frequently called upon to make assessments of the rationality or irrationality of persons for a variety of medical-legal purposes. A key category is that of evaluations of a patient's capacity to grant informed consent for a medical procedure. A diagnosis of mental illness is neither a necessary nor a sufficient condition for a finding of incompetence. The notion of competency to grant consent, which is a mixed psychiatric-legal concept, shares some features with philosophical conceptions of rationality, but differs from them in a number of important respects. This article describes the actual practice of psychiatrists when making such judgments, along with the standards of competency they employ. A comparison is made between those notions of competency and predominant philosophical conceptions of rationality.     

Marital crisis and therapy in their social context

The objective in this paper is to analyze the macro-social trends regarding divorce in Israel and their implications for family therapy. Four macro-social aspects are discussed: legal aspects, demographic trends, single-parenthood, and remarriage. Family therapy strategy must take into account the particular problems of the different varieties of Israeli families, especially the needs of the children, who have no less a stake in the therapy's success than their parents.     

PRACTICAL SOLUTIONS TO THE SURPRISE-EXAMINATION PARADOX*

In this paper I consider the surprise examination paradox from a practical perspective, paying special attention to the communicative role of the teacher's promise to the students. This perspective, which places the promise within a practice, rather than viewing it in the abstract, imposes constraints on adequate solutions to the paradox. In the light of these constraints. I examine various solutions which have been offered, and suggest two of my own.

DEVELOPMENT AND TESTING OF THE ATTITUDES TOWARD FEMINISM AND THE WOMEN'S MOVEMENT (FWM) SCALE

This article outlines the development and testing of the Attitudes Toward Feminism and the Women's Movement (FWM) Scale, a brief measure of affective attitudes toward the feminist movement. Thurstone's (1959) method of equal-appearing intervals was used initially to create the final 10-item summated rating (Likert) scale. Establishment of internal consistency reliability and construct (convergent and discriminant) validity was determined on a sample of 117 female and male college students. Results suggested a highly internally consistent and valid attitudinal measure. Additional evidence for the validity of the FWM is discussed in terms of research in which it has been successfully used.     

Training letter-to-sound connections: The efficacy of tracing

There is evidence that training letter-to-sound connections can be important for future reading development. The present study involved training letter-sound connections for two groups of prereaders equivalent in their IQ, knowledge of letters and age, to examine the importance of tracing letters in order to learn such connections. All children were trained individually. Each 15-minute training session was divided into three parts. In one 5-minute part of each session, the “Letter” group pronounced a letter shown on a computer and traced it on the screen with a pen, while the “Shape” group traced non-letter shapes. In the second 5-minute part, the Shape group named letters and watched them being traced while the other group watched the program tracing non-letter shapes. Thus both groups experienced the same letter-sound training and tracing activity, but only the Letter group experienced both in conjunction with each other. In the final 5-minute session both training groups received training in phonemic awareness training for 5 minutes. It was found that both groups improved significantly on a letter-to-sound test relative to a control group not receiving such training. However, only the Shape group significantly improved in a sound-to-letter test. It is concluded that tracing vertically on a computer screen does not appear to be advantageous for teaching letter-sound connections for this age range and can even be a distraction for learning sound-letter connections.     

Systematic observation methods in the study of small groups

A comparison was made between the Bales and the Carter-Haythorn-Meirowitz-Lanzetta methods of systematic observation. The comparison was limited to the categorizing of verbal behaviour. It was found that there are several deficiencies in the latter method with respect to the classes used, and that satisfactory observer reliability could not be obtained. By using the Bales method, on the other hand, fairly high total observer reliabilities were achieved, and even the category reliabilities in various classes turned out to be satisfactory, provided the category frequencies were large enough.
