Determination of a behavioral transfer function: White-noise analysis of session-to-session response-ratio dynamics on concurrent VI VI schedules

Six pigeons were exposed to concurrent variable-interval schedules in which the programmed reinforcer ratios changed from session to session according to a pseudorandom binary sequence. This procedure corresponded to the stochastic identification paradigm (“white-noise experiment”) of systems theory and enabled the relation between log response ratios in the current session and log reinforcer ratios in all previous sessions to be determined. Such dynamic relations are called linear transfer functions. Both nonparametric and parametric representations of these, in the form of “impulse-response functions,” were determined for each bird. The session-to-session response ratios resulting from the session-to-session pseudorandom binary variations in reinforcer ratios were well predicted by the impulse-response functions identified for each pigeon. The impulse-response functions were well fitted by a second-order dynamic model involving only two parameters: a time constant and a gain. The mean time constant was 0.67 sessions, implying that the effects of abrupt changes in log reinforcer ratios should be 96% complete within about five sessions. The mean gain was 0.53, which was surprisingly low inasmuch as it should equal the sensitivity to reinforcement ratio observed under steady-state conditions. The same six pigeons were subjected to a similar experiment 10 months following the first. Despite individual differences in impulse-response functions between birds within each experiment, the impulse-response functions determined from the two experiments were essentially the same.     

Behavioral economics of drug self-administration. II. A unit-price analysis of cigarette smoking.

In behavioral economics, the ratio of response requirement to reinforcer magnitude is referred to as unit price. Previous research with nonhuman subjects has demonstrated that (a) comparable amounts of food are consumed at the same unit price even though different response requirements and reinforcer magnitudes comprise that unit price and (b) increases in unit price decrease food consumption in a positively decelerating fashion. The present study assessed the generality of these findings to the cigarette smoking of 5 human volunteers. During approximately 18 3-hr sessions, various combinations of response requirement (fixed-ratio 200, 400, and 1,600) and reinforcer magnitude (1, 2, and 4 puffs per bout) were arranged. Consumption (i.e., the number of puffs) generally was comparable at the same unit price independent of the response requirement and reinforcer magnitude comprising that unit price. In addition, increasing unit price generally decreased consumption in a positively decelerating fashion. These results extend the generality of the unit-price analysis to human cigarette smoking. Moreover, these results further support the position that reinforcer magnitude and response requirement are functionally equivalent and interact to determine consumption. The concept of unit price, by integrating and summarizing the effects of those two operations, provides a more parsimonious explanation of the results than do separate evaluations of the effects of response requirement and reinforcer magnitude.     

The interaction between stimulus and reinforcer control on remembering.

In a symbolic matching-to-sample task, 6 pigeons obtained food by pecking a red side key when the brighter of two white lights had been presented on the center key and by pecking a green side key when the dimmer of two white lights had been presented on the center key. Across Part 1 and Parts 6 to 10, the delay between sample-stimulus presentation and the availability of the choice keys was varied between 0 s and 25 s. Across Parts 1 to 5, the delay between the emission of a correct choice and the delivery of a reinforcer was varied between 0 s and 30 s. Although increasing both types of delay decreased stimulus discriminability, lengthening the stimulus-choice delay produced a greater decrement in choice accuracy than did lengthening the choice-reinforcer delay. Additionally, the relative reinforcer rate for correct choice was varied across both types of delay. The sensitivity of behavior to the distribution of reinforcers decreased as discriminability decreased under both procedures. These data are consistent with the view, based on the generalized matching law, that sample stimuli and reinforcers interact in their control over remembering.     

Small Unit Leader Perceptions of Managing Soldier Behavioral Health and Associated Factors

This investigation explored squad leaders’ perceptions of their roles managing subordinate soldiers’ behavioral health (BH) needs. The data were obtained through an anonymous survey of 458 squad leaders (i.e., small unit leaders who oversee 4–10 soldiers). More than 80% of squad leaders perceived management of soldier BH needs before, during, and after treatment as their responsibility, and felt comfortable and capable of executing these roles. Latent class analysis was used to determine groups of “most active,” “moderately active,” and “least active” leaders. Multinomial logistic regression was used to compare the least and most active classes. The most active leaders were more likely to report high BH knowledge, dedication to a common purpose, and low levels of “associative” stigma. These results should inform leader management of soldier BH. Future research should examine active leader characteristics and whether evidence-based training can increase support for preventing and managing BH issues.     

Attentional bias and emotional reactivity as predictors and moderators of behavioral treatment for social phobia

Cognitive behavioral therapy (CBT) is a well-established treatment for anxiety disorders, and evidence is accruing for the effectiveness of acceptance and commitment therapy (ACT). Little is known about factors that relate to treatment outcome overall (predictors), or who will thrive in each treatment (moderators). The goal of the current project was to test attentional bias and negative emotional reactivity as moderators and predictors of treatment outcome in a randomized controlled trial comparing CBT and ACT for social phobia. Forty-six patients received 12 sessions of CBT or ACT and were assessed for self-reported and clinician-rated symptoms at baseline, post treatment, 6, and 12 months. Attentional bias significantly moderated the relationship between treatment group and outcome with patients slow to disengage from threatening stimuli showing greater clinician-rated symptom reduction in CBT than in ACT. Negative emotional reactivity, but not positive emotional reactivity, was a significant overall predictor with patients high in negative emotional reactivity showing the greatest self-reported symptom reduction.

The Gap Between Science and Practice: How Therapists Make Their Clinical Decisions

Recent surveys have found that many patients are not receiving empirically supported treatments and that therapists may not update their knowledge of research. Studies have found that therapists prefer to use their clinical experience rather than research findings to improve their practice, although cognitive behavioral (CB) practitioners have been found to use research more frequently than therapists of other theoretical orientations. The organization in which therapists work has been shown to impact attitudes toward working practices, but studies have not examined whether workplace requirements to use research affect therapists’ practice. Studies to date have mainly been conducted in North America. These findings may not be generalizable to the United Kingdom where there is a National Health Service (NHS), which requires the use of empirically supported treatments. The first part of this study aimed to investigate which factors were influential in therapists’ choice of theoretical orientation and to see whether CB practitioners differed from other therapists in the factors that influenced their choice of theoretical orientation. The second part tested whether therapists’ theoretical orientation or their workplace influenced the frequency with which they used research in their clinical decision-making. The final part investigated whether being a CB practitioner or working in the NHS was associated with having a favorable attitude toward research. An online survey was sent to 4,144 psychological therapists in England; 736 therapists responded (18.5%). Therapists reported that research had little influence over their choice of theoretical orientation and clinical decision-making compared to other factors, specifically clinical experience and supervision. CB practitioners and NHS therapists, regardless of their orientation, were significantly more likely to use research than other therapists and were more likely to have a positive attitude toward research.     

Using individual differences to predict job performance: correcting for direct and indirect restriction of range

The present study investigates the relationship between individual differences, indicated by personality (FFM) and general mental ability (GMA), and job performance applying two different methods of correction for range restriction. The results, derived by analyzing meta-analytic correlations, show that the more accurate method of correcting for indirect range restriction increased the operational validity of individual differences in predicting job performance and that this increase primarily was due to general mental ability being a stronger predictor than any of the personality traits. The estimates for single traits can be applied in practice to maximize prediction of job performance. Further, differences in the relative importance of general mental ability in relation to overall personality assessment methods was substantive and the estimates provided enables practitioners to perform a correct utility analysis of their overall selection procedure.
