Spatial memory in rats under restricted viewing conditions

In a procedure devised by J. A. Walker and D. S. Olton (Learning and Motivation, 1979, 10, 73–84), rats were placed on two arms of a four-arm radial maze and then were placed in the center of the maze to test how accurately they could choose the alleys on which they had not been placed. In three experiments, the conditions under which animals viewed the environment from the arms were varied. In Experiment 1, both the extent of spatial view and the exposure time were varied factorially in a within-subjects design; animals viewed the environment down a tunnel or had a 180° or 360° view, and subjects were allowed to view the environment for either 2 or 20 sec. In Experiment 2, a between-subjects design was used, in which different groups of subjects were tested repeatedly under either the tunnel, 180°, or 360° conditions. Both experiments showed that animals could avoid the arms previously visited at no better than a chance level of accuracy in the tunnel viewing condition but could perform with progressively better accuracy at the 180 and 360° viewing conditions. Animals also were more accurate in Experiment 1 after viewing for 20 sec than after viewing for 2 sec. Experiment 3 involved a procedure in which restricted viewing conditions were used both during arm placements and testing. Animals tested under tunnel viewing eventually achieved above-chance performance with this procedure, but did not exceed chance as rapidly as groups tested with 45 and 90° views of the environment. These results suggest that animals can learn about their position in a spatial environment through observation and that an animal's ability to locate its position is directly related to the extent of the surrounding environment it can see and the length of time it is allowed to look. The implications of these findings for list and map hypotheses of spatial memory representation are discussed.     

The Moderating Effects of Accountability on the Conscientiousness-Performance Relationship

The interaction of Conscientiousness and accountability was investigated in the context of performance outcomes using a cognitive performance task, and this interaction was found to be statistically significant. In a laboratory experiment with 95 student-participants, under conditions of accountability, more conscientious individuals performed at higher levels than less conscientious people in support of the hypothesis. Under conditions of no external accountability, the relationship between Conscientiousness and performance was not significant. No main effects were found.     

Teaching as Confessing Redeeming a Theological Trope for Pedagogy

By reclaiming the role of confession in the classroom, we can rethink the fundamental question of what it means to teach religion. That is, the project of thinking about the religious dimension of pedagogy should also force us to rethink religious studies in general. Pedagogy, after all, is not an incidental expression of religious commitments but is instead one significant place where the religious imagination takes shape and form. All religious reflection is confessional, because scholarship is only one form of pedagogy, and teaching is the act of saying who we are, where we are from, and where we are going.     

Transferability of a role-oriented interest Inventory from men to women in church-related occupations

This study considers the feasibility of using the Inventory of Religious Activities of Interests and the extensive data for men associated therewith in the counseling of women who may be interested in entering occupations related to the Protestant Church. Mean scores on the ten scales of the Inventory for men and women in nine categories of church-related occupations and for the total sex groups were compared in respect to similarity of shape of mean score profile and in respect to the level of mean scores. In addition, the ability of the Inventory to differentiate among groups (11 for women; 10 for men) for the sexes separately was considered. The results suggest that while men and women as total groups appear to differ in their interests as measured by the IRAI, the data for men and women in the respective specialties are sufficiently similar in respect to profile shape and mean score level to justify the use of the Inventory and the normative data for men in the counseling of women. The results suggest the Inventory differentiates among subgroups of men more effectively than it does among subgroups of women. But there are data to suggest that this difference may be more apparent than real.     

The teacher-pupil interaction scale: An empirical method for analyzing the interactive effects of teacher and pupil behavior

The Teacher-Pupil Interaction Scale was developed for use by educational consultants to provide teachers with systematic data for analyzing and improving the learning of pupils. The scoring protocol provides for the simultaneous rating of sequential teacher-pupil interactions; a single mark is used to designate both teacher and pupil behavior at each five-second interval. Observations of a target pupil are alternated with other pupils in the classroom to serve as a point of comparison with the target pupil and to provide a general assessment of the classroom climate. Using the sequential record of their verbal and nonverbal interactions with students, teachers can pinpoint conditions serving both as antecedents and consequents of current student behavior. Armed with this information, teachers can effect changes in their instructional program to increase the rate of desired behaviors and eliminate or reduce unwanted responses.     

THE NATURE OF PERSONAL FREEDOM

For there is a struggle for human freedom to be waged not only against external centers of irresponsible power but against those equally irresponsible internal forces which in varying degrees dominate the mind and heart of every man. Because of them, man may be free politically and economically, yet deeply enslaved. He can be free of all arbitrary external controls, yet live under the power ol internal compulsions which make of him an automaton: insatiable in his needs, inflexible in his methods, and incapable of learning intellectually or of maturing emotionally through experience. Because of these inner processes, man may be an absolute monarch or a constitutionally elected president, an abstract artist or a precise scientist, a criminal or a clergyman, yet not possess the greatest of all freedoms–the freedom to change.¹     

A new history of Hartley's Observations on Man

In 1749 David Hartley published his Observations, a work of great historical significance, yet the history of the Observations has been frequently debated. Establishing an accurate history of the Observations is, therefore, warranted. This has been undertaken here by reexamining known source materials, as well as additional primary documents not previously applied to Hartley studies. Significant historical information has been gleaned from transcribing the Hartley-Lister shorthand correspondence. The synthesis of material from these sources has led to a new history of the stages of conceptual development, composition, and publication of Hartley's Observations that differs substantially from previous accounts.     

Effects of a limited nap on night sleep in older subjects

The night sleep of sixteen 50-60-year-old women, which had been preceded by either afternoon naps or no-nap control periods, was assessed by polygraphic and subjective measures. There were 2 nap and 2 non-nap nights. The naps were limited to a 1-hr opportunity. The measures of all subjects, good nappers (more than 20-min sleep on both nap occasions), and subjects with 50-min or more nap time, were separately analyzed. The null hypothesis of a nap effect could not be rejected. Within limits, naps may be recommended to offset the common night-time awakenings in older persons.
