ESTABLISHING OPERATIONS AND REINFORCEMENT EFFECTS

Positive reinforcement procedures have had a major impact on educational programs for the developmentally disabled; nevertheless, variation in reinforcer effectiveness both within and across individuals is a common phenomenon. This study examined one class of variables—establishing operations—that might influence the effectiveness of reinforcers. Five developmentally disabled adult males participated. Responding on one of two motor tasks—switch closure or block placement—was assessed during baseline, satiation, and deprivation conditions with respect to three classes of consequences: small food items, music, and social praise. Deprivation and satiation conditions were constructed so as not to alter significantly the normal course of events in a subject's day. For example, food deprivation entailed scheduling sessions just prior to a subject's regular lunch, and social deprivation involved limiting a subject's access to social interaction for 15 minutes, during which time the subject had access to an assortment of other activities. Results showed that each stimulus class functioned as reinforcement with different degrees of effectiveness during satiation versus deprivation conditions. These results are discussed in light of previous research on enhancement of reinforcer efficacy as well as the assessment and identification of functional reinforcers, and implications are presented for future research and client habilitation.     

Relative deprivation based on occupation: An effective predictor of Chinese life satisfaction

Relative deprivation (RD) refers to the fact that individuals may feel deprived of some desirable thing in social comparison relative to a reference group. Occupational group is widely recognized as the essential reference group and generally used to compare differences in earnings and social position. Four waves' data from the Social Attitudes Survey of Urban‐Rural Residents (China) (SAS‐C; 2005/2007/2008/2009) were used to compute to Stewart's new measure of RD for different occupational groups and its relationship to life satisfaction (a cognitive component of subjective well‐being). Results showed that both economic RD (defined as individuals' RD of material benefits, such as income, wealth etc.) and social status RD (defined as individuals' RD on their evaluation of social status) consistently predicted Chinese life satisfaction for a period of time from 2005 to 2009; meanwhile, individual economic RD was moderately correlated to social status RD. The effects of RD and some demographic variables on life satisfaction are discussed and possible improvements for future research are suggested.     

Relative deprivation,national GDP and right-wing populism: A multilevel,multinational study

We conducted a secondary analysis of the 2018 (ninth round) European Social Survey dataset (N = 19,512, nested in 24 countries) to analyse the association between relative deprivation and right-wing populist voting, moderated by participants' income and their country's GDP. A multilevel moderated model showed that relative deprivation, income and GDP had no association with right-wing populist votes by themselves. However, income and GDP moderated the relation between relative deprivation and right-wing populist votes, that was significant for participants with high incomes and for those living in wealthy countries. The strengths, limitations and future developments of the study are discussed.     

Reconceptualizing relative deprivation in the context of dramatic social change: the challenge confronting the people of Kyrgyzstan

The present study investigated the relationship between Temporal Collective Relative Deprivation and collective well‐being in the context of dramatic social change in Kyrgyzstan. Traditional research has evaluated Temporal Collective Relative Deprivation by comparing a group's present situation to a point in the recent past or future. We argue that a reconceptualization of Temporal Collective Relative Deprivation is needed. We hypothesized, first, that examining several, as opposed to a single, points of comparison will better predict collective well‐being. Secondly, we hypothesized that the points of comparison that will best predict collective well‐being will not necessarily correspond to the most recent past or future. Third, we hypothesized that the overall trajectory of Temporal Collective Relative Deprivation perceived across time will influence the level of collective well‐being. A sample of 565 Kyrgyz participants completed a questionnaire. Hierarchical regressions and group‐based trajectory modeling confirmed our three hypotheses. Theoretical and methodological implications of the findings are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Development and validation of a measure of perceived relative deprivation in childhood

Childhood adversity is known to impact psychological functioning and physical health in later life, but research into the mechanisms responsible has been impeded by the absence of a suitable retrospective measure of perceived relative deprivation in childhood. We developed and validated scores of the Perceived Inequality in Childhood Scale (PICS). In total, 683 students from Liverpool University, Liverpool Hope University and the University of East London were sampled by means of online methods. The data were separated using odd–even methods and an exploratory factor analysis identified a 2 factor solution: perceived relative deprivation (12 items) and family social capital (4 items). The measure was then subjected to confirmatory factor analysis and a 3 factor structure was revealed. The scale was further validated against Index of Multiple Deprivation (IMD) scores of childhood addresses. The PICS is a brief, practical scale suitable for both small and large-scale research studies.     

Information Deprivation Trauma: Definition,Assessment, and Interventions

Information deprivation trauma (IDT; Schild & Dalenberg, 2012b) is a concept that has not been adequately addressed in the trauma literature. IDT is a concept requiring a negative emotional response (e.g., fear, helplessness, horror) consequent to (a) a lack of understanding of the extent, magnitude, consequences, and probability of a current or impending meaningful event; and (b) an inability to access information about this event that would reasonably allow a person to prepare, appropriately respond, or self-protect. Arguments are presented that information deprivation itself might constitute a trauma, in addition to and apart from the possibility that information deprivation might enhance vulnerability to traumatization. Clinical examples are provided, and the Information Deprivation Trauma Interview (IDTI) is introduced for use in clinical and research settings.     

Effects of deprivation upon counting and timing in rats

Two procedures were used in an investigation of the effects of deprivation upon counting and timing. Under the first procedure, fixed minimum interval (FMI), the rat received liquid reinforcement every time it pressed bar B after having waited a minimum of 5 sec following a press on bar A. Under the second procedure, fixed consecutive number (FCN), reinforcement was delivered every time the rat pressed bar B following a run of at least four consecutive responses on bar A.

Water deprivation was varied over a set of values ranging from 4 to 56 hr. Deprivation had almost no effect on the waiting time in the FMI procedure, or on the number of responses per run in the FCN procedure. With both procedures, increasing deprivation shortened the pause between reinforcement and the next response. In the FCN procedure, the speed with which the runs were executed increased with increasing deprivation, although the number of responses in these runs was relatively unaffected.

     

Predicting self‐esteem during unemployment: The effect of gender,financial deprivation,alternate roles,and social support

Two hundred and one unemployed men and women participated in a cross‐sectional study that assessed self‐esteem, financial deprivation, number of alternate roles, and use of social support. Financial deprivation, alternate roles, and social support each had a main effect on self‐esteem. In addition, these variables interacted with gender to affect self‐esteem. Specifically, financial deprivation had a greater negative association with self‐esteem in men as compared with women. In contrast, alternate roles and social support had a stronger positive relationship to self‐esteem in women than in men. The incorporation of these findings into intervention programs for unemployed persons is discussed.     

Freedom deprivation in prisons of Serbia

The subject of this research is the deprivation of freedom at two time points. A total of 490 convicts from open, semi‐open, and closed prisons participated in the research. Freedom deprivation intensity was determined by using the freedom deprivation scale (α = .93). The results of the research indicate that almost all the participants reported freedom deprivation. The prison type had an impact on freedom deprivation intensity, whereas an influence of the ward type on deprivation was not demonstrated. Freedom deprivation intensity was consistent from the turn of the century to the present day.     

Inferring the Meaning of Work From the Effects of Unemployment

Questionnaire data from 148 unemployed individuals were analyzed to investigate the meaning for work. Both economic and experiential functions of work were examined. The data revealed that, as predicted, increasing length of unemployment was associated with increasing economic and experiential deprivation. Economic deprivation, in turn, was associated with both more experiential deprivation and lower subjective well-being. Unexpectedly, experiential deprivation was not related to subjective well-being. The results indicate the importance of the economic functions of work in people's lives.     

Comparisons and perceived deprivation in ethnic minority settings

Two studies investigated comparison choices among ethnic minorities and majorities. The perceived status of the self vis-á-vis different comparison targets also was assessed. Antecedents and consequences of comparisons and relative deprivation were examined. Predictions were derived from social comparison, stigma, social identity, and relative deprivation research. Two surveys were conducted, one in London with mainly Asian participants (N = 235) and one in Germany with Turkish and Aussiedler participants (N = 166) and German majority members (N = 351). Participants preferred intragroup and temporal comparisons (with other ingroup members and with the self in the past) to various types of cross-group comparisons (with outgroup members). Perceived similarity and contact with a target positively predicted interest in comparing with this target, and perceived higher status of the target was a negative predictor. Some evidence was found that feelings of deprivation depend on comparison choices. Deprivation negatively predicted self-esteem and life satisfaction. Deprivation and group identification were negatively correlated.     

Longitudinal effects of egoistic and fraternal relative deprivation on well-being and protest

According to the social justice literature, fraternal relative deprivation causes protest, but has little impact on well-being. We consider this view incomplete and predict that fraternal relative deprivation can impair well-being if it is enduring and difficult to ameliorate. As part of a longitudinal study of the German unification process, measures of egoistic relative deprivation, fraternal relative deprivation, life satisfaction, mental health, and protest were obtained on three occasions of measurement (1996, 1998, 2000) from a demographically heterogeneous sample of 1276 East German citizens. Model tests and parameter estimation were performed with LISREL. In line with our predictions, unique longitudinal effects of fraternal relative deprivation on well-being were identified. No longitudinal effect of fraternal relative deprivation on protest was identified.     

Does latent deprivation lead to psychological distress? Investigating Jahoda's model in a four‐wave study

Unemployment has serious negative effects on psychological health, and yet the underlying mechanisms remain unknown. According to the latent deprivation model, it is the lack of latent benefits of work associated with unemployment, which leads to psychological distress. In a four‐wave study among employed persons, unemployed persons, and persons out of the labour force (OLF) (N_T1= 1,026), this assumption was tested cross‐sectionally as well as longitudinally. Multiple mediation analyses show the expected differences in distress between the employed, unemployed, and OLF persons and indicate that part of this difference can be explained by differential access to the latent benefits. Furthermore, cross‐lagged structural equation modelling confirms that a deprivation of latent benefits leads to a decrease in psychological health 6 months later. Findings regarding the different quality of the latent benefits in relation to each other and over time when predicting psychological health are discussed.     

Falsification of matching theory: changes in the asymptote of Herrnstein''s hyperbola as a function of water deprivation.

Five rats pressed levers on variable-interval schedules of water reinforcement at various levels of water deprivation. In one phase of the experiment, three deprivation conditions that replicated conditions in Heyman and Monaghan (1987) were arranged, along with three less extreme deprivation conditions. In a second phase, water deprivation was arranged so that subjects were exposed to a greater range of access to water per day. Herrnstein's hyperbola described the rats' response-rate data well. The y asymptote, k, of the hyperbola appeared roughly constant over the conditions that replicated those of Heyman and Monaghan, but decreased markedly when less extreme deprivation conditions were included. In addition, k varied systematically when the second method of arranging deprivation was used. These results falsify a strong form of matching theory and confirm predictions made by linear system theory.     

Effects of stimulus control and deprivation upon discriminative responding

Discriminative responding in pigeons was studied under multiple variable-interval extinction schedules in which extinction was correlated with either a tone or a white keylight. The two procedures resulted in weak and strong stimulus control, respectively. In the first experiment, there was no interaction between schedule components when stimulus control was strong and reinforcement was omitted under the previously reinforced component. However, there was marked induction between components when stimulus control was weak and responding was extinguished under the previously reinforced component. In the second experiment, hours of food deprivation was varied under two levels of stimulus control. Deprivation mainly influenced response rates under the extinction stimulus, with greater absolute rate increases occurring the lower the existing level of stimulus control. Increases in responding during the extinction stimulus were four times as great from 24 to 72 hours of deprivation as from 24 to 48 hours under conditions of both high and low stimulus control.     

Working in the hidden economy: Associations with the latent benefits and psychological health

Hidden economy working can provide income and cushion the financial hardship during unemployment; can it also substitute for some latent functions of regular employment? According to Jahoda's theory, the latent functions include the time structure, regular shared experience, information about personal identity, a link with the collective purpose, and enforced regular activity. This article explores whether the undeclared working reduces the degree of deprivation of these functions during unemployment and, consequently, improves the psychological health of a person. The data were collected from a sample of unemployed persons (N = 1138) registered with the Croatian Employment Bureau. A series of questions about their day-to-day activities were used to estimate the amount of undeclared working, an ad hoc developed scale to assess the extent of their latent deprivation, and the SF-36 Health Survey to measure their psychological health. The ANCOVA revealed that the participants who were often engaged in the hidden economy working exhibited reduced latent deprivation and improved psychological health compared to those who were sometimes engaged. Hierarchical regression analysis indicated that their better psychological health was partially mediated through reduced latent deprivation. However, the unemployed who were never engaged in undeclared working exhibited a relatively high psychological health as well.     

Perceived qualifications,resource abundance,and resentment about deprivation

Two experiments tested the hypothesis that perceptions of being well qualified for a desired object will decrease individuals' resentment about deprivation when opportunities for obtaining the object are good (i.e., when the resource is abundant), but increase resentment when the resource is scarce. In the first experiment, unemployed nurses participated in a survey of the job situation for nurses. The initial questions in the survey were designed to manipulate respondents' perceptions of (a) their qualifications for employment, by affecting their perceived similarity to employed nurses (similar vs different), and (b) the job potential for unemployed nurses (improve vs worsen). In the second experiment, subjects competed over a number of trials with other participants for money that they had previously been promised. Some of the subjects had practiced the task ahead of time (qualified subjects), whereas others had not (unqualified subjects). In addition, the number of payments that were allegedly available was varied (many vs few). In both experiments, the manipulation of good qualifications reduced resentment when the resource was abundant, but did not significantly affect resentment when the resource was scarce. The implications of these results for understanding the determinants of resentment about deprivation are discussed.     

Personality as a predictor of the objective and subjective impact of sleep deprivation

Although, impairments following sleep deprivation have been clearly demonstrated in the literature, researchers have found a wide range of individual variation in response to sleep deprivation. The relationship between personality and the subjective and objective impact of sleep deprivation was examined using the Epworth Sleepiness Scale, Stanford Sleepiness Scale, Sleep Hygiene Index, Profile of Mood States, an oddball reaction time test, a multi-task cognitive performance battery (SynWin), and the NEO Personality Inventory Revised. Subjects (14 males, 14 females, mean age 20.5) were sleep deprived for 28–35 h and during this time were allowed access to self-reported typical amounts of tobacco, caffeine, and food. Post sleep deprivation: (a) higher neuroticism scores were related to participants feeling sleepier, experiencing more mood disturbance, and performing inferiorly on a behavioral task; (b) subjects scoring as introverts showed more compromised behavioral performance compared to extraverts. The authors suggest that potential moderating variables of the relationship between personality and sleep deprivation such as stimulant use, food intake, and socialization warrant further investigation.

Sleep deprivation and hallucinations. A qualitative study of military personnel

Much anecdotal evidence suggests that sleep deprivation not only impairs performance, but also brings about other extraordinary effects like hallucinations. However, knowledge about how sleep deprivation may trigger hallucinations is limited. To qualitatively describe hallucinatory experiences during sleep deprivation 12 male military officers from the Norwegian Armed Forces who all had experienced at least one sleep loss-induced hallucinatory experience were recruited. Data were collected and analyzed by semi-structured interviews and thematic analysis. This resulted in the identification of three distinct main themes: (1) Modalities, (2) circumstances/triggers and (3) reactions to hallucinations. Hallucinations were experienced in several modalities (visual, auditory and multi-modality), although visual hallucinations seemed to dominate. Typical reported circumstances/triggers were sleep loss, physical exhaustion, time-of-day, low calorie intake, mental exhaustion and lack of external stimuli (low sensory and social input, boring situations, and monotonous activity). Negative emotions were dominant during the hallucinatory episodes. Often some reasoning and checking on behalf of the officers were necessary to differentiate between real percepts and hallucinations. In some cases the hallucinations caused erroneous actions. Retrospectively, most officers viewed their hallucinatory experiences in light of positive emotions and several emphasized having learned something from them. The results are discussed in relation to the existing literature and suggestions for future studies are outlined.
