One week of solitary confinement of prison inmates produced significant changes in their EEG frequency and visual evoked potentials (VEP) that parallel those reported in laboratory studies of sensory deprivation. EEG frequency declined in a nonlinear manner over the period. VEP latency, which decreased with continued solitary confinement, was shorter for these 5s than for control 5s whose VEP latency did not change over the same period. Experimental 5s who had been in prison longer had shorter VEP latencies than relative newcomers to the prison.

“…but not all, investigations. Although auditory vigilance (a test of concentration) was found to be significantly impaired (Zubek, Aftanas, Hasek, Sansom, Schludermann, Wilgosh, & Wincour, 1962) digit span (a test of attention) was not (Goldberger & Holt, 1958;Zubek et al, 1962;Zubek, Bayer, Milstein, & Shephard, 1969). Some investigations demonstrated defects in memory and in new learning ability.…”

The purpose of this study was to describe changes that occur in mental status in older adults during 4 days of hospitalization in an acute‐care setting. It was hypothesized that elderly patients would experience significant changes in all components of mental status (i.e., level of consciousness, orientation, attention/concentration, memory, higher cognitive functions) during this period of time. A sample of 25 individuals ranging in age from 65 to 89 years was obtained from the medical and surgical units of an acute‐care hospital. Each individual's mental status was evaluated twice using a mental status examination designed for the study. The first assessment was conducted on the afternoon of admission day, and the second was completed on the fourth hospital day. Statistically significant changes in three components of mental status were found: disorientation increased, level of consciousness declined, and memory improved. The significance of these findings for nursing is discussed.

“…Vivid dreams and memories, inefficiency of thought, loss of contact with reality, and visual experiences are reported in equal frequency in both groups 70 . When immobilization in recumbency is accompanied by visual and auditory deprivation, similar but more extensive impairment in intellectual and perceptual functioning occurs 71 …”
