Response Speed as a Function of Different Reinforcement Conditions and a Ready Signal

80 preschool children were each administered 40 trials on a key-pressing apparatus. Marbles served as reinforcers. So given a ready signal performed faster than So not given a ready signal. There was no difference in the mean speeds of the partial reinforcement and the varied delay groups, but both of them performed faster than the constant delay group. The continuously and immediately rewarded group performed faster than the other three groups. The effect of a particular reward condition manifested itself on the immediately following trials. Interpretation in terms of competing responses was offered

Rotational alignment near N=Z and proton-neutron correlations

The effects of the residual proton-neutron interactions on bandcrossing features are studied by means of shell model calculations for nucleons in a high-j intruder orbital. The presence of an odd-nucleon shifts the frequency of the alignment of two nucleons of the other kind along the axis of rotation. It is shown that the anomalous delayed crossing observed in nuclei with aligning neutrons and protons occupying the same intruder subshell can be partly attributed to these residual interactions.Comment: 14 pages, including 5 eps figures submitted to Phys.

We are bitter, but we are better off: Case study of the implementation of an electronic health record system into a mental health hospital in England

In contrast to the acute hospital sector, there have been relatively few implementations of integrated electronic health record (EHR) systems into specialist mental health settings. The National Programme for Information Technology (NPfIT) in England was the most expensive IT-based transformation of public services ever undertaken, which aimed amongst other things, to implement integrated EHR systems into mental health hospitals. This paper describes the arrival, the process of implementation, stakeholders' experiences and the local consequences of the implementation of an EHR system into a mental health hospital

Race as a Dimension in Children\u27s TV Advertising: The Need for More Research

Most of the current research in the area of television advertising to children deal entirely with white populations. This exclusion of black subjects exists in spite of an abundance of research in education, sociology and psychology which suggests differences in the socialization of black and white children. The present article reviews major studies of television and children and black versus white child development. The authors conclude with several suggestions for further research

Healing Images: A Historical Outline of their Use in Western Medical and Psychotherapeutic Traditions

The ancient literature of numerous cultures abounds with accounts of spectacular cures resulting from the imaging process. These accounts are now being corroborated by a growing body of clinical and experimental evidence. The effectiveness of mental imagery in the treatment of a wide variety of problems has been convincingly documented (Sheikh, 1983). This paper outlines the use of imagery in Western medical as well as psychotherapeutic traditions. It concludes with a discussion of the reasons that make imagery an excellent healing agent

Recall of Group Tasks as a Function of Group Cohesiveness and Interruption of Tasks

The paper demonstrates that the motivational concepts underlying the Zeigarnik effect pertaining to individuals attempting to achieve their personal goals can be applied to individuals who are working to attain the group goals. However, this is true only for individuals in cohesive groups as opposed to noncohesive groups
