Effects of reinforcement context on choice

Two experiments investigated the effects of successive reinforcement contexts on choice. In the first, concurrent variable-interval schedules of primary reinforcement operated during the initial links of concurrent chains. The rate of this reinforcement arranged by the concurrent schedules was decreased across conditions: When it was higher than the terminal-link rate, preference for the higher frequency initial-link schedule increased relative to baseline. (During baseline, a standard concurrent-schedule procedure was in effect). When the initial-link reinforcement rate was lower than the terminal-link rate, preference converged toward indifference. In the second experiment, a chain schedule was available on a third key while a concurrent schedule was in effect on the side keys. When the terminal link of the chain schedule was produced, the side keys became inoperative. Availability of the chain schedule did not affect choice between the concurrent schedules. These results show that only when successive reinforcement contexts are produced by choice responding do those successive contexts affect choice in concurrent schedules.     

Critical reflection and critical reflexivity as core processes for critical WOP: Precarious employment as an example

This work suggests that researchers in work and organizational psychology (WOP) and WOP as a discipline would benefit from a critical perspective on their own research and practice. We highlight the value of critical reflection and critical reflexivity on contexts of research and practice in order to increase the practical impact of WOP for everyone. First, we outline how WOP currently fails to address pressing global issues, such as precarious employment, by focusing on work-related phenomena in affluent societies and neglecting issues relevant to the majority of the world's working population. Second, we present a heuristic framework of four fundamental contextual components that are important to consider when engaging in a continuous process of critical reflection and critical reflexivity: history; economy and politics; society and culture; and personal background. Third, we illustrate why these contexts are important for WOP with the example of precarious employment. Considering context more explicitly is important for future WOP research because context not only co-determines the experiences of the working people under investigation but also the subjectivity of researchers themselves. We hope to encourage WOP researchers to engage in critical reflection and critical reflexivity to promote a more critical WOP.     

The Multitextured Lives of Women of Color

In this commentary, I suggest that our work with women of color should be held together by three primary threads: (a) appreciation for history as we decipher and interpret the adaptive strategies of women of color; (b) recognition of the intersections of race, gender, and class as central to our work; and (c) self-critical examination of the meanings we attach to difference. The papers in the current special issue provide good examples regarding the importance of each thread. I argue that attention to these three themes should help us to keep our focus on contextually driven questions and to move forward our appreciation for the lives of women of color.     

The paradox of preference for unreliable reinforcement: The role of context and conditioned reinforcement

We discuss Belke and Spetch's (1994) work on choice between reliable and unreliable reinforcement. The studies by Belke and Spetch extend a line of basic research demonstrating that under certain experimental conditions in a concurrent chains procedure, pigeons prefer an alternative that produces unreliable reinforcement. The authors describe the variables that influence preference for unreliable reinforcement, including the signaling and the duration of the reinforcement schedules, the context in which the signaling stimuli occur, and the effects of conditioned reinforcement. Hypothetical applied examples that address these variables are provided, and their influence on preference for unreliable reinforcement in humans is discussed. We conclude by suggesting a line of applied research to examine the relationship between these variables and a preference for unreliable reinforcement.     

Content variations and performance on formal operational tasks by gender,social class and ability1

The role of task content, gender, social class and cognitive ability in performance on two formal operational tasks is explored in this paper. The participants were 110 Icelandic 12-year-olds, early and late developers, males and females from all socio-economic groups. Two tasks of variable isolation (the pendulum and three content versions of the “plant” problem) and two measures of volume conservation (three traditional tasks and three tasks formally identical whose content was pictorial social play) were presented individually in a school setting. The results suggest that content variations have differential consequences for the performance of early and late developers at age 12. Both the nature of logical competence and task content affect solutions, as suggested by Overton and collaborators in 1987. Some social class and gender differences were observed on two Piagetian tasks (pendulum and volume), which was reduced by changing the task content in the case of social class but not in that of gender. As the gender difference in volume conservation was not reflected ins chool achievement nor on other cognitive tasks it was interpreted as a gender bias. The findings are discussed in view of recent literature on the development of cognitive theory with increased emphasis on context and meaning in a post-structural intellectual climate.     

Cultural attitudes: in contexts of argumentation and explanation

Traditionally, attitudes are supposed to predict behavior. However, due to their poor performance, we are sometimes advised to abandon the notion. The present study attempts to preserve the concept but takes attitudes to be evaluative goals accomplished through interactional, especially argumentative and explanatory activities. The paper uses reasoned-discourse analysis and demonstrates the attainment of positive attitudes towards the Dutch by expatriate Chinese intellectuals in the Netherlands by attending to a variety of argumentative and explanatory strategies in their interview talk. Results suggest that there is good empirical reason to believe that attitudes are accomplishments of communicating actors' rhetorical contextualizations.     

The relationship between qualitative and quantitative research: Lessons from feminist psychology

The dominant methodological approach in psychological research has involved the use of quantitative methods within a positivist framework. In this article we argue that both qualitative and quantitative methods have their strengths and limitations, depending on the research question under investigation. We examine some of the advantages of qualitative methods, paying particular attention to the value of such methods for feminist researchers. We challenge the positivist assumption that all research should be apolitical and value-free, arguing that the political context in which all research studies take place plays an important role in decisions about the appropriate research methods to use. Despite the value attached to qualitative methods by feminist researchers, there may be projects for which quantitative methods, or a combination of qualitative and quantitative techniques, are more suitable. We draw on examples from our research on the transition from school to the job market for young people, and a study of 16- to 19-year-old first time mothers to illustrate these points, examining the practical implications of our arguments for applied social psychology research.     

Engineering ethics, individuals, and organizations

This article evaluates a family of criticism of how engineering ethics is now generally taught. The short version of the criticism might be put this way: Teachers of engineering ethics devote too much time to individual decisions and not enough time to social context. There are at least six version of this criticism, each corresponding to a specific subject omitted. Teachers of engineering ethics do not (it is said) teach enough about: 1) the culture of organizations; 2) the organization of organizations; 3) the legal environment of organizations; 4) the role of professions in organizations; 5) the role of organizations in professions; or 6) the political environment of organizations. My conclusion is that, while all six are worthy subjects, there is neither much reason to believe that any of them are now absent from courses in engineering ethics nor an obvious way to decide whether they (individually or in combination) are (or are not) now being given their due. What we have here is a dispute about how much is enough. Such disputes are not to be settled without agreement concerning how we are to tell we have enough of this or that. Right now we seem to lack that agreement—and not to have much reason to expect it any time soon. An earlier version of this paper was presented at the 2005 conference, Ethics and Social Responsibility in Engineering and Technology, Linking Workplace Ethics and Education, co-hosted by Gonzaga University and Loyola Marymount University, Los Angeles, CA, USA, 9–10 June 2005.     

Stimulus control of delayed matching in pigeons: Directed forgetting

Pigeons were trained in delayed matching-to-sample with two postsample stimuli. A postsample R-cue signaled that a matching choice phase would follow. A postsample F-cue signaled that a matching choice phase would not follow. Previous research found reduced matching accuracy on F-cued probe trials when comparison stimuli were presented in the choice phase. The present four experiments systematically varied the events following an F-cue to determine the conditions under which the F-cue reduces delayed-matching accuracy. When F-cues and R-cues controlled different behavior, matching on probe trials was poor. When both cues controlled the same behavior, matching on probe trials was good. This result is best explained by the theory that comparison stimuli retrieve the sample representation, but only in the behavioral context established by the R-cue. The present research supports the view that response-produced stimuli serve a contextual role in animal short-term memory.
