Measuring violence on television

Television violence has been measured in numerous studies. However the amounts reported vary considerably depending on the definitions provided of violence and the sampling periods adopted. Studies that have followed the methodology of Gerbner are more easily compared and point to rates of around 5-6 violents acts per hour on prime time television in most countries. The rate of violence on British television is considerably lower than this and evidence points to a recent decline. However, traditional content analyses are limited and provide little understanding of television as a narrative art.     

Brief systemic work in psychiatric settings where a family member has been diagnosed as schizophrenic

In this paper I discuss work with the families of patients diagnosed as schizophrenic. The focus is on two particular aspects of such work: special features of therapy with these families and the important preparatory contextual work that needs to be done with colleagues in the professional network.     

THE MORALITY OF NEW REPRODUCTIVE TECHNOLOGIES

Science is revolutionizing human reproduction. New techniques are already with us, such as artificial insemination, the freezing of sperm, in vitro fertilization and the use of surrogate mothers. Artificial wombs are clearly on the horizon.     

TERRORISM, SELF-DEFENSE, AND WHISTLEBLOWING

In a recent paper given at a Symposium on terrorism, Thomas Hill, Jr., discussed "Making Exceptions Without Abandoning the Principle: Or How a Kantian Might Think about Terrorism." His argument, however, after acknowledging that "terrorists of course often claim to have morally worthy ends and also means that are morally justified in the context," and further stating that "some such claims deserve a serious hearing,"¹ goes on to deal with the related question of
…what one may justifiably do in response to morally indefensible terrorism.²     

On the interdependence of temporal and spatial judgments

Three experiments are reported on the tau and kappa effects, the dependence of judgments of distance upon duration (tau) and of judgments of duration upon distance (kappa). In Experiment 1, three lights in a horizontal sequence were used to define two temporal and two spatial intervals over a total duration of 160 msec. The subject was required to choose the shorter of either the two durations or the two distances. The results confirmed Collyer’s (1977) findings that the two effects are inconsistently observed across subjects when the display duration is brief. In Experiment 2, display duration was systematically manipulated from 160 to 1,500 msec. It is argued that relative temporal judgments should become easier as the total display duration is increased and that, hence, the kappa effect should become less marked. On the other hand, relative spatial judgments should become more difficult as the total duration of the display is increased, and the tau effect should become more marked. The data were in conformity with the hypothesis. In Experiment 3, data are presented for a tau experiment which fit the assumption that the effect depends upon a weighted average of distance and the expected distance which would be traversed in the given time at constant velocity.     

A comparison of the environments of day care centers and group day care homes for 3 year olds

Caregiver-child interaction and social participation were compared in community-based day care centers and group day care homes for three year olds. Use of group day care homes made it possible to control for group size and adult-child ratio. Day care homes were found to be more structured in terms of curriculum, and more flexible in terms of overall schedule and social-emotional climate. Adult child interaction was of higher quality during structured periods in day care homes. Social participation was of higher quality in day care homes. The adult-child interaction in both types of day care was impersonal and neutral in affective tone.     

Memory for numbers: Nominal vs. magnitude information

Across three paired associate learning experiments, the recall of four-digit number responses to word stimuli favored the most significant digit over the least significant (magnitude encoding rather than exhibiting typical bowed serial position functions (nominal encoding). Only with instructions emphasizing exact recall of each individual digit did recall functions revert to bowed curves. The results are interpreted as evidence for two kinds of number coding in semantic memory.     

Teaching autistic children to use extra-stimulus prompts

Autistic children often do not transfer from extra-stimulus prompts, and thus do not utilize a frequent learning aid. It has been hypothesized that this is due to stimulus overselectivity; a failure to respond to simultaneous multiple cues. This study was designed to determine if autistic children who initially respond only to single cues can be taught a set to respond to two cues and subsequently utilize an extra-stimulus (pointing) prompt. Four autistic children were pretested to determine if they could learn a complex visual discrimination by either trial and error or an extra-stimulus prompt fading procedure. Since they did not, the children were then taught to respond to two cues through a multiple-cue training procedure and subsequently tested to determine if they could now utilize a pointing prompt. Results indicated that while all four children initially did not transfer from an extra-stimulus (pointing) prompt, they did so subsequent to multiple-cue training. The results are discussed in terms of implications for treatment (remediating overselectivity) and in relation to normal child development.
