Escape from serial stimuli leading to food

If the functional relations governing the strength of a conditioned reinforcer correspond to those obtained with other Pavlovian procedures (e.g., Kaplan, 1984), the termination of stimuli appearing early in the interval between successive food deliveries should be reinforcing. During initial training we presented four key colors, followed by food, in a recurrent sequence to each of 6 pigeons. This established a baseline level of autoshaped pecking. In later sessions, we terminated each of these colors or only the first color for a brief period following each peck, replacing the original color with a standard substitute to avoid darkening the key. Pecking decreased in the presence of the last color in the sequence but increased in the presence of the first. In accord with contemporary models of Pavlovian conditioning, these and other data suggest that the behavioral effects of stimuli in a chain may be better understood in terms of what each stimulus predicts, as measured by relative time to the terminal reinforcer, than in the exclusively positive terms of the traditional formulation (Skinner, 1938). The same model may also account for the initial pause under fixed-interval and fixed-ratio schedules of reinforcement.     

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.     

The asymptotic posterior normality of the latent trait for polytomous IRT models

Chang and Stout (1993) presented a derivation of the asymptotic posterior normality of the latent trait given examinee responses under nonrestrictive nonparametric assumptions for dichotomous IRT models. This paper presents an extention of their results to polytomous IRT models in a fairly straightforward manner. In addition, a global information function is defined, and the relationship between the global information function and the currently used information functions is discussed. An information index that combines both the global and local information is proposed for adaptive testing applications.This research was partially supported by Educational Testing Service Allocation Project No. 79424.

Identity and injustice: Exploring women's participation in collective action

The present study is an investigation into the social psychological factors associated with women's reported participation in a range of different types of political action in the context of gender relations. At time 1,610 women were asked to rate their readiness to participate in various actions and to provide measures of social beliefs. Factor analysis extracted four types of action: participation in women's groups, collective protest, informal participation, and individual protest. One year later, at time 2, a subgroup of the same women were asked to say how much they had actually participated over the previous 12 months. Reported participation was related to gender identity, collective relative deprivation, efficacy, collectivist orientation, and identification as an activist. Regression analysis showed that identification as an activist was by far the most powerful correlate of participation, followed by gender identity; and that gender identity also played a role in moderating relationships between reported participation and other predictor variables. These findings show the important role of identity processes underlying participation in collective action and suggest the need to develop interaction models of participation.     

Human observing: maintained by negative informative stimuli only if correlated with improvement in response efficiency.

Two experiments investigated the effect of observing responses that enabled college students to emit more efficient distributions of reinforced responses. In Experiment 1, the gains of response efficiency enabled by observing were minimized through use of identical low-effort response requirements in two alternating variable-interval schedules. These comprised a mixed schedule of reinforcement; they differed in the number of money-backed points per reinforcer. In each of three choices between two stimuli that varied in their correlation with the variable-interval schedules, the results showed that subjects preferred stimuli that were correlated with the larger average amount of reinforcement. This is consistent with a conditioned-reinforcement hypothesis. Negative informative stimuli--that is, stimuli correlated with the smaller of two rewards--did not maintain as much observing as stimuli that were uncorrelated with amount of reward. In Experiment 2, savings in effort made possible by producing S- were varied within subjects by alternately removing and reinstating the response-reinforcement contingency in a mixed variable-interval/extinction schedule of reinforcement. Preference for an uncorrelated stimulus compared to a negative informative stimulus (S-) decreased for each of six subjects, and usually reversed when observing permitted a more efficient temporal distribution of the responses required for reinforcement; in this case, the responses were pulls on a relatively high-effort plunger. When observing the S- could not improve response efficiency, subjects again chose the control stimulus. All of these results were inconsistent with the uncertainty-reduction hypothesis.     

Bayesian Gaussian distributional regression models for more efficient norm estimation

A test score on a psychological test is usually expressed as a normed score, representing its position relative to test scores in a reference population. These typically depend on predictor(s) such as age. The test score distribution conditional on predictors is estimated using regression, which may need large normative samples to estimate the relationships between the predictor(s) and the distribution characteristics properly. In this study, we examine to what extent this burden can be alleviated by using prior information in the estimation of new norms with Bayesian Gaussian distributional regression. In a simulation study, we investigate to what extent this norm estimation is more efficient and how robust it is to prior model deviations. We varied the prior type, prior misspecification and sample size. In our simulated conditions, using a fixed effects prior resulted in more efficient norm estimation than a weakly informative prior as long as the prior misspecification was not age dependent. With the proposed method and reasonable prior information, the same norm precision can be achieved with a smaller normative sample, at least in empirical problems similar to our simulated conditions. This may help test developers to achieve cost-efficient high-quality norms. The method is illustrated using empirical normative data from the IDS-2 intelligence test.     

Perceptions of Sense of Control,Relative Deprivation,and Expectations of Young Jews and Palestinians in Israel

Abstract

The author focused on the impact of personal deprivation, sense of control, and social context on the future expectations of advantaged and discriminated groups. Analysis of 6,430 Jewish and Palestinian high school students in Israel showed that Palestinian students had lower expectations and stronger feelings of deprivation than Jewish students. Also those who felt deprived had lower expectations regarding the prospects of marriage and the probability of owning a home and a car and of holding a permanent job. However, sense of control influenced these expectations more than did feelings of deprivation. The findings indicated that the processes by which future expectations are formed might be different for Jewish and Palestinian students and that these differences are—at least in part—related to long-term discrimination against Palestinians in Israel.     

Beyond Social and Temporal Comparisons: The Role of Temporal Inter-Group Comparisons in the Context of Dramatic Social Change in Mongolia

ABSTRACT

In this paper, we argue that the target of comparison should be taken into consideration when evaluating the associated outcomes of negative comparisons in the context of dramatic social change. To achieve this general goal, we considered five distinct targets of comparison: social (my group versus another group), temporal (my group across time), and temporal inter-group (my group versus another group across time). We hypothesised that in times of constant social change, two points of anchors (social and temporal) are simultaneously needed to evaluate one's position. A total of 236 high school and university students from Mongolia participated in the study. We used hierarchical regression analysis to test our hypotheses. As predicted, we found that temporal inter-group comparisons are better predictor of collective esteem than their social and temporal counterparts. Moreover, the link from past and future temporal inter-group comparisons to collective esteem was negative as hypothesized. Results are discussed in terms of theoretical implications.     

Does participation in research lead to changes in attitudes among clinicians? Report on a survey of those involved in a French practice research network

Background/Objective: With increasing awareness of some of the limitations of randomised controlled trials as the ‘gold standard’ of psychotherapy evaluation, researchers at the start of the twenty‐first century have focused on a number of new priorities: developing studies in natural conditions; investigating the psychotherapeutic process to better understand the conditions, causes and mechanisms of change; and reducing the gap between clinicians and researchers. Can these three interrelated objectives be combined? Method: A French psychotherapy practice‐based research network (PRN) is used as a field of research for these issues. A survey was used to investigate the conditions that encouraged the clinicians to participate in the PRN study within the context of clinicians’ general opposition to research. Results: Several elements emerged as the key to clinicians’ positive involvement in research: the methodology implemented (intensive case studies during one year); the choice of measures; the constant attention to the practicalities and the potential contribution of studies to clinical practice; the organisation of work in peer groups; the training methods; the use of new information technologies and the sense of participation in a project that would support the profession. Implications: These elements are briefly discussed in relation to the question of how best to encourage clinicians to engage with research.
