Toward a quantitative theory of punishment

In two experiments, pigeons' key pecking for food on concurrent variable-interval schedules was punished with electric shock according to concurrent variable-interval punishment schedules. With unequal frequencies of food but equal rates of punishment associated with the two keys and at several intensities of shock, the response and time allocation of all six pigeons overmatched the obtained relative frequency of food. The overmatching was predicted by a subtractive model of the interaction between punishment and positive reinforcement but not by two alternative models. Increases in the k and r_e parameters of the generalized matching law could not account for the observed shifts in preference.     

The puzzle of responding maintained by response-contingent shock.

Four squirrel monkeys were first exposed to a sequence of procedures that reliably generate responding maintained by brief response-contingent electric shocks arranged according to a fixed-interval schedule. After responding had become stable on the fixed-interval schedule, additional contingencies were added in tandem, whereby after completion of the interval, the spacing of responses affected shock delivery. In one procedure, responses had to be spaced more widely than their previous median value if shock were to be delivered. In the other procedure, responses had to be spaced more closely to produce shock. On the first of these procedures, decreased but stable responses rates would indicate that shock functioned as a positive reinforcer; on the second, increased response rates would indicate the positively reinforcing function. Instead, response rates accelerated on the procedure that targeted more widely spaced responses for shock delivery, and decelerated or ceased on the procedure that arranged for shocks to be produced by more closely spaced responses. Consistent with other recent findings, these results question the interpretation of performances maintained by response-contingent shock as engendered by positive reinforcement and are consistent with aversive-control interpretations. The details of that aversive control are not entirely clear, however, and these same procedures would be informative if applied to shock-maintained behavior that is generated in other ways.     

Bar press and bar release as avoidance responses

Two experiments were performed in which rats had to avoid shock by both pressing and releasing a bar within specified intervals. When the release-shock interval was held constant and the press-shock interval was increased, response rate decreased and bar holding increased. When the press-shock interval was held constant and the release-shock interval was increased, both response rate and bar holding decreased.     

Time allocation in concurrent schedules: the effect of signalled reinforcement

The responses of five pigeons were reinforced on concurrent variable-interval variable-interval reinforcement schedules in which changeover key responses changed the stimulus and reinforcement schedules associated with the food key. While the reinforcement availability in one component remained unchanged throughout the experiment, the reinforcement availability in the other component was, during several conditions, signalled by the onset of an additional discriminative stimulus. During unsignalled conditions, both the relative frequency of responding and the relative time spent in each component approximated the obtained relative reinforcement frequency in each component. The effect of signalling reinforcer availability in one component was to (1) reduce responding in the signalled component to near-zero levels, and (2) increase the relative time in the unsignalled component, without a corresponding increase in the obtained relative reinforcement frequency. The magnitude of the increase in relative time in the unsignalled component decreased as the overall frequency of reinforcement increased. This deviation in the matching relation between relative time and the obtained relative reinforcement frequency was eliminated if the overall reinforcement frequency was increased before the signal was introduced and then, without removing the signal, gradually reduced.     

Still No Evidence For Temporally Extended Shock-frequency Reduction As A Reinforcer.

There is no consensus and very little overlap in the criticisms of my target article. Because the primary consequences of avoidance behavior are by definition alterations in the distribution of shocks in time, any theory about the reinforcement of such behavior necessarily must begin with that dimension. However, the safety‐signal version of two‐process theory calls on positively and negatively correlated stimuli, including the responses themselves serving as stimuli, to transmit the effects of those alterations to the relevant behavior. Meanwhile, the Herrnstein—Hineline single‐process theory hypothesizes an additional source of reinforcement: a direct effect of reduction in the density of shock over some extended period of time. I can find no data that selectively support that hypothesis.     

The molarity of molecular theory and the molecularity of molar theory.

Dinsmoor (2001) rejects shock-frequency reduction as a reinforcer for avoidance behavior, and considers this to be an invalidation of so-called molar avoidance theory. This is a narrow view of operant avoidance theory, for which shock-frequency reduction is by no means the only reinforcer.     

Functions of Career Resilience Against Reality Shock,Focusing on Full‐time Employees During Their First Year of Work

The purpose of this study was to examine the role of career resilience in coping with reality shock. Career resilience was defined as psychological traits that help individuals to cope with career risks and promote their own career development. It consisted of five factors: (a) ability to cope with problems and changes; (b) social skills; (c) interest in novelty; (d) optimism about the future; and (e) willingness to help others. Full‐time employees in their first year of employment (N = 233) participated in an online survey to measure career resilience, reality shock, and the degree of career development. The study found that coping with changes and being optimistic about the future could prevent the experience of reality shock. The result also suggested that good social skills prevented experience of reality shock from inhibiting career development.     

Understanding the positive and negative outcomes of developmental challenges on the social psychology of female executives in top management teams

Drawing on social identity theory, this conceptual article proposes how working in a male-dominated top management team (TMT) leads to changes in the social psychology of female executives over time. Further, it simultaneously incorporates the role of various factors to develop a comprehensive understanding of positive as well as negative change experiences of female executives. Based on thorough review and integration of the relevant literature from the domains of organizational behaviour, gender management, and psychology, key themes have been extracted and a conceptual model has been proposed. It is suggested that female executives are likely to face epistemological shock after becoming a part of male-dominated TMTs; however, proactive interactions and development of their cultural toolkit is expected to polish leadership capabilities and improve leader identity in them. Conversely, challenges in developing their cultural toolkit may lead to experiences of emotional exhaustion and the eventual psychological detachment of female executives from their teams and work environment. Unlike the focus of existing literature on general social and cultural challenges faced by female workers, this research offers a unique theoretical direction regarding the essence of extensive psychological changes and their long-term prospects for females in male-dominated TMTs. Finally, it also offers practical implications for highlighting various ways to encourage proactivity and social support for creating diversity and inclusion-based leadership in organizations.     

Effect of attention control on sustained attention during induced anxiety

Anxiety has wide-reaching and complex effects on cognitive performance. Although it can intrude on cognition and interfere with performance, it can also facilitate information processing and behavioural responses. In a previous study, we showed that anxiety induced by threat of shock facilitates performance on the Sustained Attention to Response Task, a vigilance test, which probes response inhibition to infrequent nogo stimuli. The present study sought to identify factors that may have contributed to such improved performance, including on- and off-task thinking (assessed with thought probes) and individual differences in attention control, as measured with the Attention Control Scale. Replicating our prior finding, we showed that shock threat significantly reduced errors of commission on the nogo trials. However, we extended this finding in demonstrating that this effect was driven by subjects with low attention control. We therefore confirm that anxiety increases inhibitory control of prepotent responses—a mechanism which is adaptive under threat—and show that this effect is greater in those who rely more upon such prepotent responding, i.e., those with low attentional control.     

Culture learning theory and globalization: Reconceptualizing culture shock for modern cross-cultural sojourners

Culture shock has long been of great concern regarding the wellbeing and mental-health of international sojourners. Over the last three decades, the world has experienced rapid globalization and the introduction of various technologies which have been found to ‘buffer’ the effects of culture shock, yet the conceptualizations concerning the nature, prevalence, and effects of this phenomenon have not been explicitly modernized to suit such a contemporary social landscape. Based on an extensive literature review, particularly concerning the research conducted with international student populations, this paper offers conceptual insight on how the experience of culture shock has evolved in the present information age, and argues modern sojourner experiences are increasingly reflective of culture learning. Specifically, this paper considers exactly how technological advancements have facilitated change in the subjective experience of the psychosocial processes during a cross-cultural immersion. A foundation for future research to explore the mechanisms of culture learning theory is also contributed.
