Economic deprivation,experiential deprivation and social loneliness in unemployed and employed youth

One hundred and forty‐eight youth were allocated to one of four occupational sub‐groups: 47 unemployed with no access to paid work; 32 unemployed with access to some paid work; 30 unemployed with access to regular paid work; and 39 full‐time employed. All participants were assessed for levels of Economic Deprivation, Experiential Deprivation, Social Loneliness and Psychological Distress. Results indicated that Economic Deprivation and Experiential Deprivation varied according to occupational status, with those full‐time employed having the least deprivation and those not attached to the work‐force experiencing the most. Levels of deprivation were related to levels of Psychological Distress. Social Loneliness also varied across the occupational groupings. The unemployed with access to regular paid work experienced the least Social Loneliness; the unemployed with no paid work experienced the most. Lastly, both Economic and Experiential Deprivation were able to predict Psychological Distress; only Experiential Deprivation was able to predict Social Loneliness. Results are discussed in the context of Jahoda's ( 1982 ) deprivation model and Weiss's ( 1973 , 1974 ) social loneliness model. Copyright © 2001 John Wiley & Sons, Ltd.     

Sleep deprivation adversely affects interpersonal responses to frustration

Sleep deprivation produces negative effects on mood and cognitive function, but existing data have almost exclusively utilized objective rating scales, which do not permit evaluation of idiosyncratic and unstructured responses. In this study, we used a semi-projective measure, the Rosenzweig Picture-Frustration (P-F) Study, to assess subjective responses to frustration following two nights without sleep. Twenty-six healthy volunteers completed the P-F at rested baseline and again following 55 h of continuous wakefulness. Participants provided written responses for an ambiguous cartoon character confronted with various frustrating situations. Relative to rested baseline, sleep deprivation was associated with altered responses on several indices, indicating a great number of uncommon types of responses, increased tendency to blame others for problems, and a reduced willingness to alleviate a conflict situation by accepting blame. Individual differences in several aspects of emotional intelligence were predictive of the extent to which responses to frustration changed with sleep loss. These findings suggest that sleep deprivation significantly weakens the inhibition of aggression and willingness to behave in ways that facilitate effective social interaction, possibly through reduced metabolic activity in prefrontal regions of the brain important for personality, affect, and inhibitory behavior.

Mediating factors in chick social pecking: 1. Effects of isolation,imprinting, and peer contact

Two experiments examined the influence of periods of social isolation on rates of intersubject pecking in pairs of domestic chicks. Of central interest was the effect of an imprinting condition wherein single birds were reared with either a red or green Styrofoam object. In the first experiment, imprinted subjects were given social pecking tests in the absence of the imprinting object, while in the second study the tests for social pecking were conducted in the presence of one of the imprinting objects. In the latter test the object was familiar to one bud of a pair, but was novel to the other animal. The results of both experiments showed that the rate of intersubject pecking of the imprinted subjects was intermediate to, and statistically different from both the low pecking rate of chicks reared in pairs and the high pecking rate of chicks reared in total isolation. The presence of a familiar object during tests in the second study seemed to serve as a secure base since chicks that had been reared with that object exhibited more social pecking than did chicks that were unfamiliar with the object. However, regardless of the provision of the object the social pecking of the imprinted chicks again fell on a point intermediate to the other groups. Hypotheses concerning a) intolerance of figureground movement and b) sheer stress of isolation were advanced to account for these results.     

Chiasm and hyperdialectic: re-conceptualizing sensory deprivation in infancy

The literature on sensory processing disorders in institutionalized infants highlights the impact of early deprivation on infant perception. Through a Merleau-Pontian, hyperdialectic analysis of the extraordinary development of infant perception under circumstances of severe deprivation the intimate link between environmental affordances and perceptual systems becomes apparent. This paper offers an updated reading of Merleau-Ponty’s late work as a philosophy of systems (“structures”, “forms”, “gestalts”, as he called them) and outlines some fertile philosophical concepts and methods developed by Merleau-Ponty in The visible and the Invisible. Merleau-Ponty’s concept of the chiasm, understood from a systems perspective, and his method of the hyperdialectic are applied in a child case study of an infant who suffered severe neglect in a Romanian orphanage.     

Plant neurobiology: from sensory biology, via plant communication, to social plant behavior

In plants, numerous parameters of both biotic and abiotic environments are continuously monitored. Specialized cells are evolutionary-optimized for effective translation of sensory input into developmental and motoric output. Importantly, diverse physical forces, influences, and insults induce immediate electric responses in plants. Recent advances in plant cell biology, molecular biology, and sensory ecology will be discussed in the framework of recently initiated new discipline of plant sciences, namely plant neurobiology.
