The Psychology of Waste

In order to avoid the appearance of wastefulness people may be motivated to make choices that compromise their own self-interest. In Experiment 1 subjects learned that Mr Munn didn't take advantage of a ‘three-pack’ which would have enabled him to see three movies for $12, the regular price being $5 per movie. Most subjects predicted that after having attended two movies at the regular price, Mr Munn would then be unwilling to purchase a ticket to attend a potentially enjoyable third movie, either because he would consider such a purchase to be wasteful or because he would be angry at having eschewed the ‘three-pack’. In Experiment 2 subjects who could use an obsolete product to ‘trade-up’ to a new model were more likely to buy the new model than were subjects who could purchase it at the identical low price. It was hypothesized that utilizing an obsolete product to obtain a new model would seem less wasteful than making an outright purchase of the new model. In Experiment 3 a large majority of subjects faced with a sunk cost situation persevered with the failing project if the alternative was selling the material ‘for its scrap value’. However, if the alternative consisted of selling the materials for an identical price to someone who could use them, then subjects were less likely to persevere with the failing project. Marketing implications and the propriety of retrospective evaluation of prior decisions were also discussed.     

Borderline personality disorder and emotion regulation: insights from the Polyvagal Theory

The current study provides the first published evidence that the parasympathetic component of the autonomic nervous system differentiates the response profiles between individuals diagnosed with borderline personality disorder (BPD) and controls. Respiratory sinus arrhythmia (RSA), a non-invasive marker of the influence of the myelinated vagal fibers on the heart, and heart period were collected during the presentation of film clips of varying emotional content. The BPD and control groups had similar initial levels of RSA and heart period. However, during the experiment the groups exhibited contrasting trajectories, with the BPD group decreasing RSA and heart period and the control group increasing RSA and heart period. By the end of the experiment, the groups differ significantly on both RSA and heart period. The correlation between the changes in RSA and heart period was significant only for the control group, suggesting that vagal mechanisms mediated the heart period responses only in the control group. The findings were consistent with the Polyvagal Theory [Porges, S. W. (1995). Orienting in a defensive world: Mammalian modifications of our evolutionary heritage: A Polyvagal Theory. Psychophysiology, 32, 301-318; Porges, S. W. (2001). The Polyvagal Theory: Phylogenetic substrates of a social nervous system. International Journal of Psychophysiology, 42, 123-146; Porges, S. W. (2003). Social engagement and attachment: A phylogenetic perspective. Annals of the New York Academy of Sciences, 1008, 31-47.], illustrating different adaptive shifts in autonomic state throughout the course of the experiment. The BPD group ended in a physiological state that supports the mobilization behaviors of fight and flight, while the control group ended in a physiological state that supports social engagement behaviors. These finding are consistent with other published studies demonstrating atypical vagal regulation of the heart with other psychiatric disorders.     

Reactions to daily events as a function of familiarity with an environment

Undergraduate participants provided measures of their psychological well‐being and described the positive and negative events that occurred each day, once during the first and second semesters of an academic year. For four of the five measures of daily well‐being, reactivity to negative events decreased from the first to second semester, whereas for four of the five measures of well‐being, reactivity to positive events did not change over the year. These results suggest that familiarity with an environment moderates reactivity to negative daily events. As people become more familiar with an environment, negative events may elicit smaller decreases in well‐being. In contrast, increases in well‐being elicited by positive events appear to be unrelated to familiarity with the environment. More broadly, these differences suggest that the reactivity to positive and negative events reflect the operation of different processes. Copyright © 2007 John Wiley & Sons, Ltd.

Establishing and Evaluating the Substantive Adequacy of Positive Behavioral Support Plans

The Individuals with Disabilities Education Improvement Act (2004) renewed the commitment to provide positive behavioral support (PBS) for students that engage in persistent problem behavior. Behavior intervention plans (also known as PBS plans) serve as legal documents that help guide the implementation of intervention strategies to encourage more positive forms of behavior. The purpose of this study was to evaluate the substantive adequacy of PBS plans developed for special education students. This was accomplished by documenting the content of plans developed by two different groups of educators using a rating instrument based on the key concepts of PBS planning. Results revealed that the majority of plans developed by teams without identified training and expertise in PBS were rated as substantively inadequate, lacking critical information related to effective behavioral support planning. The implications of the results for everyday practice in the schools and directions for future research are discussed.     

Applying the behavioral economics principle of unit price to DRO schedule thinning

Within the context of behavioral economics, the ratio of response requirements to reinforcer magnitude is called unit price. In this investigation, we yoked increases in reinforcer magnitude with increases in intervals of differential reinforcement of other behavior (DRO) to thin DRO intervals to a terminal value.     

Functional analysis and treatment of problem behavior of elderly adults in long-term care

Functional analyses were conducted for the problem behavior of 3 older adults in a long-term care setting. Two of the problem behaviors were maintained by attention, and a third was maintained by escape from demands. Function-based interventions were implemented that resulted in decreases in problem behavior in each case. Implications for the use of functional analysis and function-based interventions in the field of gerontology are discussed.     

Finding Direction When You are Lost in Translation

In this article introducing the special issue, factors involved in making the translation from lab findings to clinical practice are discussed. The common themes which pervade all the articles are articulated. Pivotal points of each individual contribution are emphasized. Particular attention is paid to developmental sensitivity, conceptualization, the courage to take on challenging psychiatric conditions, clinical innovation, and clear guidelines for practitioners.     

Aging and intraindividual variability in performance: analyses of response time distributions

It has been suggested that older adults are more variable in their performance because they are more prone to lapses of either attention or intention. In the present experiment, 9 young and 9 older adults each performed nearly 2000 trials of a same-different judgment task. As expected, older adults were slower and more variable than young adults. When the age-related difference in speed was taken into account, however, the older adults were, if anything, less variable than the young adults. When younger and older adults' RT distributions were analyzed using quantile-quantile plots and by fitting ex-Gaussian and Weibull functions, there was no consistent evidence that older adults' distributions were more skewed than young adults', as would be predicted by age-related increases in lapses of attention or intention. Importantly, there was a positive, linear relation between RT and intraindividual variability, and the same relation was observed both within subjects (practice increased speed and reduced variability) as well as between subjects (regardless of age, slower individuals were more variable). Thus, the present results suggest that there may be a general law governing the relation between average RT and variability, and that the greater performance variability of older adults primarily reflects their greater average RTs.     

IS MATCHING INNATE?

Experimentally naive mice matched the proportions of their temporal investments (visit durations) in two feeding hoppers to the proportions of the food income (pellets per unit session time) derived from them in three experiments that varied the coupling between the behavioral investment and food income, from no coupling to strict coupling. Matching was observed from the outset; it did not improve with training. When the numbers of pellets received were proportional to time invested, investment was unstable, swinging abruptly from sustained, almost complete investment in one hopper, to sustained, almost complete investment in the other-in the absence of appropriate local fluctuations in returns (pellets obtained per time invested). The abruptness of the swings strongly constrains possible models. We suggest that matching reflects an innate (unconditioned) program that matches the ratio of expected visit durations to the ratio between the current estimates of expected incomes. A model that processes the income stream looking for changes in the income and generates discontinuous income estimates when a change is detected is shown to account for salient features of the data.
