Predicting environmental learning from spatial abilities: An indirect route

Relationships among spatial abilities, as assessed by a battery of psychometric tests and experimental tasks, and environmental learning, as assessed by a series of macrospatial tasks, were examined in two studies using confirmatory factor analysis with directional paths. The initial study indicated the utility of a five-factor model, one (general spatial ability) derived from psychometric tests, two (spatial-sequential memory and spatial perspective-taking latency) from experimental tasks, and two (topological knowledge and Euclidean direction knowledge) from measures of environmental learning. The best fitting path model further indicated that the spatial-sequential memory factor mediated the relationship between general spatial ability and topological knowledge, and that perspective-taking latency mediated the relationship between general spatial ability and Euclidean direction knowledge. The second study confirmed the five-factor path model using a different participant sample and environmental setting. The only failure to replicate involved the path between perspective-taking latency in the lab and Euclidean direction knowledge in the environment. Results indicate that the relationship between basic spatial abilities and environmental learning is significantly mediated by cognitive processes that can be assessed using laboratory tasks.     

Couples coping with cancer: Research issues and recent findings

The diagnosis of cancer in one partner can impose numerous changes for both the individual diagnosed with cancer and his or her healthy spouse. In this article, the literature on spouse social support in the context of cancer is reviewed. The importance of understanding support given and received within a close relationship using an interactional, contextual perspective is emphasized. Examining support-related interactions and understanding the personal characteristics that determine the type and amount of support that providers give and the kind of support individuals prefer, and investigating why significant others respond in supportive or critical ways is important. In addition, the study of support interactions must be placed in the both in the context of a marriage and in the context of a catastrophic life event such as cancer. A longitudinal study of patients with gastrointestinal cancer and their healthy partners was undertaken to examine these issues, and the design of this study is described. General problems conducting research with couples undergoing a severe life stressor as well as specific problems our research group has encountered while setting up a research program in the cancer setting are reviewed.     

On the relationship between empathy and the actor versus observer hypothesis

Subjects listened to a tape recording of a dyadic interaction. It was predicted that the observational set instructions received by the subjects (to empathize with one member of the dyad or not to empathize with this person) would create evaluation effects similar to those created for attributions of responsibility by actor-observer differences: The actor would receive credit for his positive outcome and blame for his negative outcome more when evaluated by nonempathizing observers, and the social environment would receive credit and blame for the actor's outcomes more when evaluated by empathizing observers. The predicted three-way interaction was obtained. Additional results are discussed in terms of previous empathy research.     

The effects of architectural change,individualized instruction,and group contigencies on the academic performance and social behavior of sixth graders

In this study architectural changes, individualized instruction, and group contigencies placed on academic work were applied to the math and language period of an initially disruptive sixth-grade classroom. Within classroom comparisons indicated that individualized instruction with group contingencies sharply increased the academic production of children from all ability levels, significantly improved social behavior, and changed the teacher's mode of instruction and interaction with the children. Individualized instruction alone had lesser effects, while the architectural changes produced no significant changes in the academic or social behavior of the children or in teacher behaviors. Results of the study are discussed in terms of improvement of the intervention procedures, focus on academic programming, and a broadening of the base of behavior modification work.     

Physiological and behavioral concomitants of mild stress: The effects of accuracy of temporal information

Sixty human subjects were exposed to a mild auditory stress after a fixed anticipatory period during which they performed a reaction time task. Suspense subjects were correctly informed of the time of onset of stress; Surprise subjects were told to expect the stress 10 min. later than it actually occurred. Subjects were provided with elapsed time information either automatically or on demand. Suspence subjects showed larger anticipatory electrodermal responses and smaller responses to stress than Surprise subjects but the two groups did not differ in their ratings of the unpleasantness of the stress. Female subjects showed greater anticipatory responses and consistently slower reaction times than males. The data are discussed in terms of explanations of the negative preception effect.     

Similarity in Religiousness of the Solicitor,the Potential Helper,and the Recipient as Determinants of Donating Behavior1

In a 2 × 2 × 2 field experiment, 107 religious and secular subjects were requested by a religious/secular solicitor to donate money for a religious/secular needy family. Religious subjects donated significantly more than secular ones. The pattern of the cell means suggested that whereas the behavior of the religious subjects was guided by the need for positive self-presentation, the secular subjects were influenced by their similarity in religiousness to the solicitor and the recipient.
