The Counselor and the School as a Social Organization

Role relations in the public school are viewed within the perspective of organization theory; the public school is like the prison and the public mental hospital in that neither client nor organization exercises choice concerning client participation in the organization. Based on previous studies of prisons and mental hospitals and on clues provided in a case study of a junior high school, it was predicted that counselors and principals would be less “custodial” in pupil control ideology than teachers. An instrument that measured pupil control ideology along a custodial-humanistic continuum was administered to 945 teachers, 181 principals, and 180 counselors. Results confirmed the predictions. Counselor adaptations to ideological conflict concerning pupil control in both the secondary and the elementary school are discussed. It was speculated that adaptations would function to reduce overt conflict and contribute to organizational equilibrium.     

The effects on eye movements of complexity,novelty, and affective tone

The major purpose of this study was to investigate the effects of stimulus complexity, novelty, and affective tone on the direction of eye movements of male college students. Motion pictures were taken of S’s eye while he viewed pairs of stimuli. In no instance, in any part of the 10 sec. viewing interval, did Ss as a group fixate longer on unpleasant stimuli when they were paired with either pleasant or neutral stimuli; and pleasant stimuli consistently dominated neutral stimuli. Also, novel stimuli and complex stimuli tended to dominate their non-novel and less complex competitors. Differences in instructions were found to markedly affect the magnitude but not the direction of fixation-dominance.     

Development of Adolescent Problem Behavior

The developmental model of adolescent antisocial behavior advanced by Patterson and colleagues (e.g., Patterson, Reid, & Dishion, 1992) appears to generalize the development of a diverse set of problem behaviors. Structural equation modeling methods were applied to 18-month longitudinal data from 523 adolescents. The problem behavior construct included substance use, antisocial behavior, academic failure, and risky sexual behavior. Families with high levels of conflict were less likely to have high levels of parent–child involvement. Such family conditions resulted in less adequate parental monitoring of adolescent behavior, making associations with deviant peers more likely. Poor parental monitoring and associations with deviant peers were strong predictors of engagement in problem behavior. These constructs accounted for 46% of the variance in problem behavior. Although association with deviant peers was the most proximal social influence on problem behavior, parental monitoring and family factors (conflict and involvement) were key parenting practices that influenced this developmental process.     

Plasma membrane ordering agent pluronic F-68 (PF-68) reduces neurotransmitter uptake and release and produces learning and memory deficits in rats

A substantial body of evidence indicates that aged-related changes in the fluidity and lipid composition of the plasma membrane contribute to cellular dysfunction in humans and other mammalian species. In the CNS, reductions in neuronal plasma membrane order (PMO) (i.e., increased plasma membrane fluidity) have been attributed to age as well as the presence of the β-amyloid peptide-25-35, known to play an important role in the neuropathology of Alzheimer's disease (AD). These PMO increases may influence neurotransmitter synthesis, receptor binding, and second messenger systems as well as signal transduction pathways. The effects of neuronal PMO on learning and memory processes have not been adequately investigated, however. Based on the hypothesis that an increase in PMO may alter a number of aspects of synaptic transmission, we investigated several neurochemical and behavioral effects of the membrane ordering agent, PF-68. In cell culture, PF-68 (nmoles/mg SDS extractable protein) reduced [³H]norepinephrine (NE) uptake into differentiated PC-12 cells as well as reduced nicotine stimulated [³H]NE release. The compound (800–2400 μg/kg, i.p., resulting in nmoles/mg SDS extractable protein in the brain) decreased step-through latencies and increased the frequencies of crossing into the unsafe side of the chamber in inhibitory avoidance training. In the Morris water maze, PF-68 increased the latencies and swim distances required to locate a hidden platform and reduced the time spent and distance swam in the previous target quadrant during transfer (probe) trials. PF-68 did not impair performance of a well-learned working memory task, the rat delayed stimulus discrimination task (DSDT), however. Studies with ¹⁴C-labeled PF-68 indicated that significant (pmoles/mg wet tissue) levels of the compound entered the brain from peripheral (i.p.) injection. No PF-68 related changes were observed in swim speeds or in visual acuity tests in water maze experiments, rotorod performance, or in tests of general locomotor activity. Furthermore, latencies to select a lever in the DSDT were not affected. These results suggest that PF-68 induced deficits in learning and memory without confounding peripheral motor, sensory, or motivational effects at the tested doses. Furthermore, none of the doses induced a conditioned taste aversion to a novel 0.1% saccharin solution indicating a lack of nausea or gastrointestinal malaise induced by the compound. The data indicate that increases in neuronal plasma membrane order may have significant effects on neurotransmitter function as well as learning and memory processes. Furthermore, compounds such as PF-68 may also offer novel tools for studying the role of neuronal PMO in mnemonic processes and changes in PMO resulting from age-related disorders such as AD.     

The classical conditioning of sleep and wakefulness

Using a metronome beat as conditioned stimulus three cases are described in which this stimulus was presented in close temporal contiguity with experimentally-induced sleep or waking. Drugs or fatigue consequent upon sleep deprivation were used as unconditioned stimuli for sleep. One of the subjects was an anxiety neurotic, one had narcolepsy and the third was a student volunteer. No EEG indication of conditioned sleep was obtained but there was evidence of conditioned relaxation in the anxiety neurotic and conditioned arousal in the other two cases.     

A comparison of “traditional” and “atypical” workers: Demographic,behavioral, and attitudinal differences

Differences among full-time (n=1066), part-time (n=132), and moonlighting employees (n=153) in a variety of occupations were examined. Moonlighters as compared to full-timers were younger, more frequently male, perceived less educational fit with their main jobs, and were primary wage earners. Full-timers as compared to part-timers were more frequently male, married, and primary wage earners. Part-timers had the greatest turnover, but no differences were detected for other withdrawal behaviors. Part-timers were more satisified with working conditions but were less satisfied with extrinsic rewards and life in general. Moonlighters expressed a stronger work ethic and placed less importance on working conditions.A version of this paper was presented at the 1991 Meetings of the Southwest Division of the Academy of Management in Houston, TX.     

The biological basis of stress management

A rationale is outlined for the inclusion of a biological approach in stress-management programmes. The biology of the stress response is described in sufficient detail to show the layperson what happens in the body when stress is experienced. An explanation of the biological basis of commonly used coping strategies is given.     

Does “inhibition of return” occur in discrimination tasks?

When attention is drawn to a location and then withdrawn, responding to a stimulus at that location may be slower than to one at a new location. This “inhibition of return” (IOR) has not been reliably demonstrated in tasks that require discrimination of targets from nontargets. The present experiments replicated IOR in detection and localization tasks only when target/nontarget discrimination was not also required. When discrimination was required, a consistent samelocation advantage occurred for repeated targets. Changed targets may, however, induce a bias toward opposite responses. The results cast doubt on IOR as a general attentional phenomenon.
