Auditory discrimination: a three-variable analysis of intensity effects

The acquisition of auditory intensity discriminations in rats trained on multiple variable-interval extinction schedules was studied as a function of some of the variables that contribute to the speed of development of differential responding and the final level attained. The effects of three variables were isolated and studied in detail: (1) the decibel difference between the discriminative stimuli (intensity difference); (2) the intensity relationship between the stimuli (relative intensity); and (3) the position of the stimuli on the intensity continuum (absolute intensity). Each of the three variables generated orderly relationships and interacted with one another to produce complex effects upon differential responding.

Retroactive raising of a sensory threshold by a contralateral stimulus

In an experiment designed to extend Howarth and Treisman's recent observations on the lowering of the visual and auditory threshold produced by a warning stimulus, it has been found that the threshold to electrical stimulation of one forearm is raised by a similar stimulus on the other forearm. As in the earlier experiments the “warning” was effective if it came 100 millisec. before or after the threshold stimulus. The effect increased with increasing warning strength over the range of five near-threshold strengths used.

These results appear to be inconsistent with the explanation previously proposed to account for the retroactive lowering of threshold. This suggested that the warning was acting simply as a marker, reducing the subject's uncertainty as to when the stimulus was coming. The fact that the rise in threshold was also induced retroactively shows that some interaction must be occurring in the central processes concerned in perception, and that it cannot be explained in terms of attenuation of the afferent volley.     

“The unbearable embeddedness of being”: Self psychology,intersubjectivity and large group experiences

Studying the large group from a self psychological perspective is a new area of exploration. The purpose of this work is to consider an expansion of the selfobject concept to include experiences in group. The groupobject is conceived as a function which addresses the inherent group needs of the individual. Just as the selfobject serves to fill in missing aspects of the self, the groupobject fills in missing aspects of the group self. The development of this concept emerged from an ongoing large group experience. It has its roots in the idea that effective group treatment can result from the recognition and support of groupobject as well as selfobject needs.This phrase, first coined by Stolorow and Atwood (1993) represents their attempt to clarify the fallacy of the isolated mind.Contexts of Being.

A family therapy workshop: a review of a two-year experiment in a Social Services Department

As family therapy ceases to be regarded as a passing fashion, and becomes recognized as a real therapeutic force, the need for new forms of support and supervision is becoming ever more apparent. This paper describes and evaluates the supervisory system for family therapy set up by an Area Group in a Local Authority Social Services Department and plans to do so in a way which has practical application for workers in a variety of settings.     

Changing self-reported physical activity using different types of affectively and cognitively framed health messages,in a student population

The present research focused upon the power of different messages to increase self-reported physical activity (PA). Five hundered and ninety six participants were randomised to one of five conditions that varied in the content of message: short-term affective, short-term cognitive, long-term affective, long-term cognitive and a no message control. PA was measured at baseline and follow-up (seven days later) was done using the Godin Leisure Time Exercise Questionnaire over the subsequent seven day period. The affective short-term message (ASM) was shown to be equally effective at increasing self-reported PA as a cognitive long-term message. Furthermore, when controlling for baseline activity levels, the ASM emerged as being the message that produced the highest levels of self-reported PA at follow-up. The findings point to the value of distinguishing between health messages in terms of the focus on affective and cognitive outcomes and the temporal nature of the outcomes (short-term or long-term).     

Measuring Customer Service Orientation Using a Measure of Interpersonal Skills: A Preliminary Test in a Public Service Organization

Organizations are placing increased emphasis on identifying individuals with customer service orientation. In the present investigation we test whether interpersonal skills, as measured through Holland and Baird's (1968) Interpersonal Competence Scale, provides a narrow, yet valid, measure of customer service orientation. Data were collected from a sample of bus transit operators. Interpersonal skills was positively related to operator self-reported performance, but was not related to supervisor ratings or objective measures of performance. Implications for the study and use of broad versus narrowly defined personality constructs in organizational settings are discussed.     

September 11 and the Role of the Theologian

As is the case with all “disasters” the nation is experiencing the various psychological stages to the September 11, 2001 disaster: threat, warning, impact, inventory, heroism, honeymoon, disillusionment, and reconstruction. In order for healing to occur from and within the religious community, theologians, pastors, and religiously–minded people must enter into these different stages of disaster and suffer–with the community. Instead of explaining September 11 from an abstract, removed stance, we ought to reveal our concerns and uncertainties about God in this situation and wonder with the rest of the community of grievers, “How has this happened?” From this place, true healing and reconstruction of the community will be possible.
