Effects of age on novelty reactions and exploration in rats

Female rats of three ages (approximately 39, 160 and 316 days) were individually observed in an exploration box which consisted of a novel and a familiar half. By means of a behaviour-sampling technique it was recorded which half of the box the rat was in and what sort of activity it was engaged in at the end of each of 90 10-sec. periods. The number of 8 × 8 in. units entered was also recorded. All rats were seen in the novel half more often than in the familiar half and this novelty preference was greatest for the youngest rats. However, exploration and inter-unit locomotion scores tended to be lower with the younger animals. For all three groups these two scores showed a significant decrement during an observation period.     

Spiritual crises facing surgical patients

Conclusion The surgical patient, then, offers the chaplain a rather special challenge. While most patients suffer a disruption of life and community, this disruption may be particularly trying to the surgical patient due to its suddenness. While most patients undergo certain fears and apprehensions upon hospitalization, it is the surgical patient who must pass through realms of the unknown and never know when this may occur. While virtually anyone may lose his desire to live, the patient who suffers severe emotional trauma in surgery, along with severe distortions of his body, may be particularly susceptible to this apprehensiveness. And while guilt is a common feeling, surgery usually presupposes a disease or accident about which the patient is prone to ask, What did I do to cause this? And finally, there are spiritual crises peculiar to particular kinds of surgery.The hospital minister, then, must learn what to expect on the surgical ward generally, and also in regard to particular types of surgical patients. At the same time he must be open to new and unusual crises. When the chaplain is aware in this way, he will be able to meet, in the lives of surgical patients, the crises that demand the flexible mobilization of all his resources.     

The Influence of Values, Information, and Decision Orders on a Public Policy Decision

An experiment was conducted to determine the influence of personal values, information, and decision order on choice and commitment to choice when the decision involved a complex matter of public policy. Findings indicated that values determined piorities, but not decisions; information did not influence choice, but had a curvilinear effect on the commitment to the choice; the decision order did not influence the components of the decision process, but did determine the proportion of value-consistent decisions. The significance of these findings to public policy and the need for future research are discussed.     

A stereotaxic implant technique for the weanling rat

A modified technique for permanently implanted electrodes in the weanling rat is presented. As a reliable and durable technique, long-term stimulation of the juvenile rat is made possible.     

A comparison of error based and time based learning measures as predictors of general intelligence

Two methodological issues involved in determining the relationship between learning and general intelligence (g) are examined. They are firstly, the use of subject learning strategies in a paired-associated learning task and secondly the importance of time in the measurement of learning efficiency. Concerning the first issue, paired-associates learning scores of subjects who were instructed in the use of an appropriate learning strategy correlated significantly with general intelligence scores while those not so instructed did not. Concerning the second issue, a time based learning measure was developed to predice the time required for complete learning in the paired-associates learning task. This measure was compared learning with a number of error-based learning measures in their ability to predict general intelligence. The time based learning measure was clearly superior to the error based measures yielding a correlation of .59 with general intelligence.     

Sex differences in Group Embedded Figures Test performance in relation to sex-role,state and trait anxiety

The Group Embedded Figures Test of field dependence (GEFT) was administered to first-year psychology students who were then assigned to four sex-role classes depending on whether or not they exceeded median masculinity and femininity scores on the Bem Sex-Role Inventory. Males achieved significantly higher GEFT scores but there were no significant sex-role effects. In a second study, other students were assigned to field dependent (DEP) and independent (INDEP) groups according to whether or not they exceeded the median GEFT performance for each sex. Between-group comparisons were then made of scores on the state and trait scales of the State-Trait Anxiety Inventory. In neither case was there a significant difference between the DEP and INDEP groups. However, for males only, there was a significant negative correlation between state and GEFT scores as well as a significant positive correlation between the two anxiety scales. Although the latter results suggested a sex difference in how the GEFT demands are perceived, it was concluded that neither sex-role nor state or trait anxiety could adequately account for consistently better male GEFT performance.     

The application of cognitive dissonance theory to consultation

Despite the importance of the consultation role for the school psychologist, the current literature on consultation has little to offer the practitioner in terms of empirically-based consultation strategies. This paper views consultation as, at least in part, a persuasive process. Cognitive dissonance theory is an extensively researched social psychological theory that predicts when a particular persuasive attempt will be successful and which has implications for consultation.

This article summarizes those aspects of dissonance theory that are most relevant to consultation, reviews the corresponding experimental support, and suggests practical applications of dissonance research and theory to consultation. Because these applications are extrapolations from research outside of consultation, they are viewed as hypotheses.     

Killing kids: The juvenile death penalty and community sentiment

In the Supreme Court's Eighth Amendment jurisprudence, “community sentiment” plays a central if not dispositive role in determining if a punishment is disproportionate. To gauge sentiment on the death penalty for juveniles, two experiments with death-qualified subjects were run, where age (a 15–25 age range) and case (heinousness) were varied in the first, and type of defendant (principal, accessory, or felony-murder accessory) and an extended age range (13–25) varied in the second. Significant age effects occur in both experiments, with approximately 75% and 65% refusing to give the death penalty for the youngest (13–15) and next youngest (16–18) groups, whereas 60% give the death penalty for the 25-year-old. In their reasons for their decisions, the killing kid was judged less blameworthy and death-worthy. Although politicians have called for “a man-sized punishment for a man-sized crime,” this community does not see that “man-sized” punishment fitting the kid.
