This study compares the relative power and robustness of the chi-square and Kolmogorov statistics with both the linear score scale and equal areas models. It is limited to the situation in which the mean and standard deviation are fixed by the hypothesis (a necessary constraint with the Kolmogorov tests). Two tables are presented which report the…

The psychometric reliability of a factor, defined as its generalizability across samples drawn from the same population of tests, is considered as a necessary precondition for the scientific meaningfulness of factor analytic results. A solution to the problem of generalizability is illustrated empirically on data from a set of tests designed to…

It was the purpose of this study to determine what teachers perceive to be the most effective behaviors supervisors employ in the individual conference setting. Results were compared with an earlier study (Gordon, 1973 "Educational Leadership").

The author attempts to determine whether or not dispositional variables involving feelings and attitudes concerning others are related to altruistic behavior and, if so, to examine their relationship to positive and negative affective arousal. (Author/RK)

The relationship between the depth to which a word is initially processed and its eventual probability of being recognized was investigated with amnesiac (alcoholic Korsakoff) patients. (Editor)

In a test of the generality of the comprehension hypothesis, educable mentally retarded children in primary classes were assigned, following pretraining measures, to experimental (n=24) and control (n=12) conditions. (Author)

This research tested Paivio's (1971) proposal that pictorial and verbal memory codes interact with space and time. This "interaction hypothesis" states that pictorial memory codes are specialized for spatial structures and verbal memory codes are specialized for temporal structures. Tests this hypothesis by exploring several variations…

Describes three experiments which investigated the mechanism underlying memory for movement-extent cues in preselection. Experiment 1 showed that memory for movement extent was better for subjects who were allowed to preselect their own standard. Experiments 2 and 3 examined the role of active movement in preselected and nonpreselected movements.…

This research was concerned with how the manner of encoding words for retention is affected by individual differences in text anxiety, and how various orienting tasks might interact with anxiety differences in determining retention. (Author/RK)

Research has shown that mental imagery stimulates various types of learning. This research investigates a procedure designed to evoke and enhance mental imagery in a classroom learning situation. The content area selected for study was spelling because so little progress in instructional approaches has been reported in the literature. Compares the…

Investigates the effects of an advance organizer lesson, presenting high-order science concepts and an elementary problem solving strategy for determining causal relations on children's use of operations of exclusion (as defined by Inhelder and Piaget, 1958). Results suggest that acceptable solutions to problems requiring the operations of…

Hypotheses tested were: social work manpower levels will correlate with population by state; number of undergraduate programs will not correlate as highly with population by state as number of graduate schools; specific social indicators will positively correlate with manpower variables; specific social indicators will correlate with population…

The lateral eye movement paradigm was employed to test the hypothesis that narrow categorizers, who are believed to be more analytic in information processing, make characteristic use of the left hemisphere, while broad categorizers, being more holistic, depend more on the right hemisphere. Results are discussed in terms of cerebral specialization…

The theoretical issue was whether a general motivation towards effectiveness or competence could be observed in the free activity of pre-school children. Implications of the concept of effectiveness-motivation were discussed. (Author/RK)

According to the learned helplessness hypothesis, the learning impairment typically displayed by subjects previously given insoluble problems results from the real learning of response-outcome independence. This learning is represented as a belief in helplessness that interferes with the subsequent acquisition of adaptive responses. Two…
