FAMILY AND JOB INFLUENCES ON ROLE SATISFACTION OF EMPLOYED RURAL MOTHERS

One hundred fifty rural employed mothers were surveyed to determine family and job predictors of satisfaction with the dual-work role. Findings indicated the saliency of job satisfaction variables in determining role satisfaction among this group of women as opposed to hypothesized reference group support variables and nontraditional value orientation variables. Discussion centered on the importance of employment outside the home to life satisfaction, particularly for mothers of older children.     

Tactile short-term memory in relation to the two-point threshold

The purpose of the present work was to discover whether there was a relationship between the sensitivity of a body site as measured by the two-point threshold and the degree or rate of forgetting of a location stimulated at that body site. In Experiment I, it was found that the higher the two-point threshold, the greater the distance between two successive points of stimulation erroneonously thought to be identical (12 body sites). In Experiment II, it was found that forgetting over time was greater when the retention interval was filled with movement or other tactile stimulation than when the retention interval was unfilled (six body sites). It was concluded that highly sensitive areas also show the least degree of forgetting as compared with less sensitive sites, but this statement should be qualified in various ways.     

Defensive Reactance of Psychologists to a Metaphysical Foundation for Integrating Different Psychologies

Psychology is fragmented and encumbered by an inordinate influence from the outdated positivistic tradition. Whereas many psychologists obdurately embrace positivism, others react strongly against it, thus producing the polarities of thinking that Kimble (1984) called the two cultures of psychology. Researchers have frequently called for more flexible epistemology, but these have not resulted in the incorporation of modernity into our science, nor have they led to metaphysical integration. This resistance on the part of many psychologists to change is attributed to cognitive defense mechanisms. The defense mechanisms are placed against feelings of inferiority. Low tolerance for ambiguity (Frenkel-Brunswik, 1949) about a subject matter that encompasses unexplainable variance in behaviors is a particular mechanism, in perceived contrast to the physical sciences. Therefore, many psychologists tend to adopt extreme views on such metaphysical issues as free will and determinism, a tendency that results in sharp divisions in the profession.     

Phencyclidine (PCP): A Dangerous Drug,but Useful in Schizophrenia Research

Phencyclidine (PCP) is a dangerous drug, and the federal government has placed it on Schedule II of the Controlled Substance Act (see http://www.mninter.net/～publish/csa2.htm#Schedule%20III). Typically, users smoke PCP, and it is often mixed with parsley, marijuana, or cocaine. Most researchers have conducted experiments on animals rather than on people, and a few have been done on persons diagnosed with schizophrenia, so answers to questions about its addictive potential or development of tolerance are not clear. In healthy volunteers, PCP can induce symptoms that mimic those of schizophrenia, lasting from a few days to more than a week. The neurotransmitter glutamate and N-methyl-D-aspartate (NMDA) appear to play a role in the mechanism by which PCP induces positive and negative schizophrenic symptoms and cognitive defects (D. C. Javitt & S. R. Zukin, 1991; A. Lahti, B. Koffel, D. LaPorte, & C. A. Tarnminga, 1995; T. W. Robbins, 1990). Because PCP can induce symptoms that are almost indistinguishable from those associated with schizophrenia, further research may lead to new medications that could be helpful to people who do not respond to neuroleptics that are currently available.     

Validation of Social Connectedness in Mainstream Society and the Ethnic Community Scales

This study examined the psychometric properties of the Social Connectedness in Mainstream Society (SCMN) and the Social Connectedness in the Ethnic Community (SCETH) Scales in two groups of ethnic minorities. We especially examined their theoretical/conceptual and empirical viability in relation to other established constructs of general social connectedness, acculturation, and enculturation. Analyses of two sets of survey data from 200 Mexican American students in California and 134 Asian international students in Minnesota supported (a) construct validity of the SCMN and the SCETH as related but distinct structures, (b) convergent and discriminant validity in relation to acculturation and enculturation, and (c) high reliability. The examination of incremental validity in predicting subjective well-being further supported their distinctive utility in addition to other established constructs of general social connectedness, acculturation, enculturation, ethnic identity, and other group orientation. Implications for future research and practice are discussed.     

Latent spatial learning in an environment with a distinctive shape

Four experiments were conducted with rats in order to determine whether being placed on a platform in one corner of a rectangular swimming pool results in latent spatial learning. Rats in Experiments 1-3 received four trials a day of being placed on the platform. During a subsequent test trial, in which they were released into the pool without the platform, the rats exhibited a preference for swimming in the correct corners of the pool (those with the same geometric properties as the corner containing the platform during training), than the two remaining, incorrect corners. This effect was seen when the interval between the final placement trial and the test trial was as much as 24 hr (Experiment 2) and after varying numbers of sessions of placement training (Experiment 3). Experiment 4 revealed that when the test took place in a kite-shaped arena, after placement training in a rectangle, a stronger preference was shown for the corner that was geometrically equivalent to the correct rather than the incorrect corners in the rectangle. The placement treatment is said to result in latent spatial learning based on the development of S-S associations.     

Changes in attention to relevant and irrelevant stimuli during spatial learning

Rats were trained in 2 experiments to find a submerged platform that was situated in 1 of 2 of the 4 corners of a rectangular pool with a curved long wall. Different landmarks occupied 2 of the corners on every trial, and the platform was always situated near a landmark. For the place group in each experiment, the location of the platform was indicated by the shape of the pool and stimuli outside the pool (place cues), but not the landmarks within the pool. For the landmark groups, the landmarks, not the place cues, indicated where the platform could be found. During Stage 2, 2 of the place cues were relevant, and 2 of the landmarks were irrelevant, for a new discrimination. The place cues better controlled searching for the platform in the place group than in the landmark group when the place cues had initially been relevant by signaling the presence (Experiment 1) or the absence (Experiment 2) of the platform. The results show that animals pay more attention to relevant than irrelevant cues.
