Persistence during and resurgence following noncontingent reinforcement implemented with and without extinction

Noncontingent reinforcement (NCR) is typically implemented with extinction (EXT) for destructive behavior reinforced by social consequences and without EXT for destructive behavior reinforced by sensory consequences. Behavioral momentum theory (BMT) predicts that responding will be more persistent, and treatment relapse in the form of response resurgence more likely, when NCR is implemented without EXT due to the greater overall rate of reinforcement associated with this intervention. We used an analogue arrangement to test these predictions of BMT by comparing NCR implemented with and without EXT. For two of three participants, we observed more immediate reductions in responding during NCR without EXT. However, for all participants, NCR without EXT produced greater resurgence than NCR with EXT when we discontinued all reinforcers during an EXT Only phase, although there was variability in response patterns across and within participants. Implications for treatment of destructive behavior using NCR are discussed.     

Bureaucracy and creativity: do they make companionable bedfellows?

This essay will look at the benefits and weaknesses of the increasingly bureaucratic nature of training structures and processes in the training of Jungian psychotherapists and analysts. The author will draw on her experiences during two different periods of time as Director of Training at the Society of Analytical Psychology in London with observations on and discussion about some of the changes that have evolved. By way of contrast, she will offer some comparisons with developments in the training of Jungian analysts in countries with little or no legacy of an analytic culture. Here, there is a need to professionalize training in Jungian analysis but the attendant growth of bureaucracy can easily come to echo the politics of non‐democratic regimes.     

The Relevance of Self‐Evaluations for Students' Career Optimism

This study investigated how people's beliefs regarding their vocational abilities (i.e., career decision self‐efficacy) are associated with their perceived academic control, self‐liking, and self‐competence. It also assessed the relevance of these 4 types of self‐beliefs for personal job optimism among 268 Croatian college students. Results indicated that participants' career decision self‐efficacy and perceptions of their chances of finding jobs nationwide were significant predictors of personal job optimism. Furthermore, the influences of self‐competence and perceived academic control on personal job optimism were mediated by career decision self‐efficacy. These results extend previous research and may be informative for vocational guidance interventions.     

Influence of Proactive Personality on Career Self‐Efficacy

This study examined the relationship between proactive personality and career decision‐making self‐efficacy. In Study 1, the authors validated the Proactive Personality Scale–Korean Short Form, using the Rasch model with 315 participants, and found that fit statistics, point‐measure correlations, and item difficulty estimates satisfy the construct validity criterion. In Study 2, the authors administered the Proactive Personality Scale, Career Decision‐Making Self‐Efficacy Scale, and Career Search Self‐Efficacy Scale to 296 freshman and sophomore college students. Hierarchical regression analyses showed that proactive personality scores explain additional variance in both career decision‐making self‐efficacy and career search self‐efficacy scores. Implications for theory and practice are discussed.     

Further analysis of subtypes of automatically reinforced SIB: A replication and quantitative analysis of published datasets

Hagopian, Rooker, and Zarcone (2015) evaluated a model for subtyping automatically reinforced self‐injurious behavior (SIB) based on its sensitivity to changes in functional analysis conditions and the presence of self‐restraint. The current study tested the generality of the model by applying it to all datasets of automatically reinforced SIB published from 1982 to 2015. We identified 49 datasets that included sufficient data to permit subtyping. Similar to the original study, Subtype‐1 SIB was generally amenable to treatment using reinforcement alone, whereas Subtype‐2 SIB was not. Conclusions could not be drawn about Subtype‐3 SIB due to the small number of datasets. Nevertheless, the findings support the generality of the model and suggest that sensitivity of SIB to disruption by alternative reinforcement is an important dimension of automatically reinforced SIB. Findings also suggest that automatically reinforced SIB should no longer be considered a single category and that additional research is needed to better understand and treat Subtype‐2 SIB.     

Empathic Skills and Cyberbullying: Relationship of Different Measures of Empathy to Cyberbullying in Comparison to Offline Bullying Among Young Adults

ABSTRACT

Empathy, as the ability to understand and feel the emotions of others, is related to less bullying behavior. However, the link of bullying behavior with self-reports of empathy seems to be stronger than with behavioral measures of empathy (e.g., empathic accuracy). Few studies have analyzed the relationship of affective and cognitive empathy to cyberbullying behavior, especially among young adults. In a quasiexperimental dyadic interaction paradigm with 72 young adults, empathic accuracy was operationalized as the match of other- and self-reported emotions for the target, and emotional congruence as the match of the target's and the perceiver's self-reported emotions. Affective and cognitive empathy, offline bullying behavior, and cyberbullying behavior were measured using self-reports. Empathic accuracy and cognitive empathy were found to be negatively linked. Emotional congruence, self-reported affective and cognitive empathy did not correlate with offline bullying behavior or cyberbullying behavior. Only empathic accuracy was significantly negatively linked to offline bullying behavior. In group tests, higher empathic accuracy (but not emotional congruence) was connected to less offline bullying behavior. In a multiple regression analysis only emotional congruence was a predictor of cyberbullying behavior. Thus, while empathic accuracy might diminish offline bullying behavior, emotional congruence might diminish cyberbullying behavior.     

Effects of shifts in food reinforcement context on rats’ consumption of concurrently available water or sucrose solution

The purpose of this study was to investigate the effects of signaled transitions from relatively rich to lean conditions of food reinforcement on drinking concurrently available water or sucrose‐sweetened water in rats. Past research demonstrated that these negative incentive shifts produce behavioral disruption in the form of extended pausing on fixed‐ratio schedules. Four male Long‐Evans rats operated on a two‐component multiple fixed‐ratio fixed‐ratio schedule. In one manipulation, the ratio was held constant and the components arranged either a large six‐pellet reinforcer (rich) or small one‐pellet reinforcer (lean). In a second manipulation, the components both produced a one‐pellet reinforcer but differed in terms of the ratio requirement, with the rich and lean conditions corresponding to relatively small and large ratios. In both manipulations, components were pseudorandomly presented to arrange four transitions signaled by retractable levers: lean‐to‐lean, lean‐to‐rich, rich‐to‐rich, and rich‐to‐lean (the negative incentive shift). During experimental conditions, a bottle with lickometer was inserted in the chamber, providing concurrent access either to tap water or a 10% sucrose solution. The negative incentive shift produced considerably more drinking than the other transitions in all rats during both manipulations. The level of drinking was not polydipsic; rather, it appears that the negative incentive shift enhanced the value of concurrently available reinforcers relative to food reinforcement.     

Escape from rich‐to‐lean transitions: Stimulus change and timeout

Extended pausing during discriminable transitions from rich‐to‐lean conditions can be viewed as escape (i.e., rich‐to‐lean transitions function aversively). In the current experiments, pigeons’ key pecking was maintained by a multiple fixed‐ratio fixed‐ratio schedule of rich or lean reinforcers. Pigeons then were provided with another, explicit, mechanism of escape by changing the stimulus from the transition‐specific stimulus used in the multiple schedule to a mixed‐schedule stimulus (Experiment 1) or by producing a period of timeout in which the stimulus was turned off and the schedule was suspended (Experiment 2). Overall, escape was under joint control of past and upcoming reinforcer magnitudes, such that responses on the escape key were most likely during rich‐to‐lean transitions, and second‐most likely during lean‐to‐lean transitions. Even though pigeons pecked the escape key, they paused before doing so, and the latency to begin the fixed ratio (i.e., the pause) remained extended during rich‐to‐lean transitions. These findings suggest that although the stimulus associated with rich‐to‐lean transitions functioned aversively, pausing is more than simply escape responding from the stimulus.     

A method for detailed movement pattern analysis of tadpole startle response

Prolonged space flight, specifically microgravity, presents a problem for space exploration. Animal models with altered connections of the vestibular ear, and thus altered gravity sensation, would allow the examination of the effects of microgravity and how various countermeasures can establish normal function. We describe an experimental apparatus to monitor the effects of ear manipulations to generate asymmetric gravity input on the tadpole escape response. To perform the movement pattern analysis, an imaging apparatus was developed that uses a high‐speed camera to obtain time‐resolved, high‐resolution images of tadpole movements. Movements were recorded in a temperature‐controlled test chamber following mechanical stimulation with a solenoid actuator, to elicit a C‐start response. Temperature within the test cell was controlled with a recirculating water bath. Xenopus laevis embryos were obtained using a standard fertilization technique. Tadpole response to a controlled perturbation was recorded in unprecedented detail and the approach was validated by describing the distinct differences in response between normal and one‐eared tadpoles. The experimental apparatus and methods form an important element of a rigorous investigation into the response of the tadpole vestibular system to mechanical and biochemical manipulations, and can ultimately contribute to improved understanding of the effects of altered gravity perception on humans.
