Motivational state regulates the content of learned flavor preferences

Rats acquired a preference for an aqueous odor (almond) presented in simultaneous compound with sucrose. Separate presentations of saccharin reduced this preference in rats with ad-lib access to food during training or at test, but not in rats that were hungry during both training and test. In contrast, separate presentations of sucrose reduced the preference for the almond irrespective of deprivation state during training and test. We interpret the results to mean that a hungry rat forms odor-taste and odor-calorie associations, and its motivational state on test determines which of these associations controls the preference. In contrast, a rat that is not hungry during training only forms an odor-taste association, and its performance on test is independent of its level of hunger.     

The grammar of approximating number pairs

In the present article, we studied approximating pairs of numbers (a, b) that were used to estimate quantity in a single phrase (“two, three years ago”). Pollmann and Jansen (1996) found that only a few of the many possible pairs are actually used, suggesting an interaction between the ways in which people estimate quantity and their use of quantitative phrases in colloquial speech. They proposed a set of rules that describe which approximating pairs are used in Dutch phrases. We revisited this issue in an analysis of Swedish and American language corpora and in a series of three experiments in which Swedish and American adults rated the acceptability of various approximating pairs and created approximating pairs of their own in response to various estimation tasks. We found evidence for Pollmann and Jansen’s rules in both Swedish and English phrases, but we also identified additional rules and substantial individual and cross-language variation. We will discuss implications for the origin of this loose “grammar” of approximating pairs.     

Working with Research Integrity—Guidance for Research Performing Organisations: The Bonn PRINTEGER Statement

This document presents the Bonn PRINTEGER Consensus Statement: Working with Research Integrity—Guidance for research performing organisations. The aim of the statement is to complement existing instruments by focusing specifically on institutional responsibilities for strengthening integrity. It takes into account the daily challenges and organisational contexts of most researchers. The statement intends to make research integrity challenges recognisable from the work-floor perspective, providing concrete advice on organisational measures to strengthen integrity. The statement, which was concluded February 7th 2018, provides guidance on the following key issues:

1. § 1.
   Providing information about research integrity
    
2. § 2.
   Providing education, training and mentoring
    
3. § 3.
   Strengthening a research integrity culture
    
4. § 4.
   Facilitating open dialogue
    
5. § 5.
   Wise incentive management
    
6. § 6.
   Implementing quality assurance procedures
    
7. § 7.
   Improving the work environment and work satisfaction
    
8. § 8.
   Increasing transparency of misconduct cases
    
9. § 9.
   Opening up research
    
10. § 10.
    Implementing safe and effective whistle-blowing channels
     
11. § 11.
    Protecting the alleged perpetrators
     
12. § 12.
    Establishing a research integrity committee and appointing an ombudsperson
     
13. § 13.
    Making explicit the applicable standards for research integrity
     

     

Deadly combinations: how leadership contexts undermine the activation and enactment of followers’ high core self-evaluations in performance

Employees with high core self-evaluations (CSE) generally perform well in their jobs. The enactment of CSE in performance occurs within contexts, and leadership is one form of context that influences the activation and expression of CSE. Drawing on theories of CSE and leader–member exchange (LMX), we characterized the leadership context as the interaction between leader CSE and LMX quality. Examination of 173 followers and their 31 leaders in a manufacturing organization showed a positive association between follower CSE and performance when the context comprised high leader CSE and high LMX. Conversely, leadership contexts comprising high leader CSE and low LMX, or low leader CSE and high LMX, resulted in a negative relationship between follower CSE and performance. We also show that low CSE followers have relatively high performance under some circumstances. Thus, we contribute to understanding how some leadership contexts undermine high CSE followers’ performance and promote low CSE followers’ performance.     

Coping Styles,Pain Expressiveness,and Implicit Theories of Chronic Pain

Whereas some individuals use active coping strategies and are able to adaptively cope with their pain, others use passive strategies and catastrophic appraisals, which are often associated with increased displays of pain behavior and negative pain-related outcomes. To investigate attribution-based implicit theories as a potential underlying mechanism that might affect coping success, we hypothesized that pain patients with an incremental implicit theory of pain (i.e., view pain as malleable) would have more active coping strategies, lower levels of pain expressiveness, and better pain-related outcomes than those with an entity implicit theory of pain (i.e., view pain as nonmalleable). Patients with chronic back pain undergoing a functional assessment completed a variety of self-report measures and participated in a pain-inducing physiotherapy procedure. The results revealed those with an incremental theory of pain used more active coping strategies, displayed less pain behavior, and reported better pain-related outcomes (e.g., lower levels of depression) than individuals with an entity theory of pain. The findings suggest implicit theories of pain may represent an underlying social-cognitive mechanism linked to important coping, emotional, and expressive reactions to chronic pain. Identifying such a mechanism may provide valuable information for the assessment and treatment of chronic pain.     

Behavioral community psychology: training a community board to problem solve

This study demonstrated the effect of training nine lower socio-economic adults participating as policy board members in a federally funded rural community project to make behaviorally defined statements to increase problem-solving behaviors in board meetings. A multiple-baseline design across subjects and skills was used to analyze the behavioral categories of: (1) stating the problem; (2) finding solutions to the problem, and (3) implementing the action to the solution. Problem-solving responses during board meetings increased for subjects following training and remained higher than baseline during follow-up.     

Operant psychology goes to the fair: Marian and Keller Breland in the popular press, 1947-1966

Marian and Keller Breland pioneered the application of operant psychology to commercial animal training during the 1940s and 1950s. The Brelands' story is relatively unknown in the history of behavior analysis. Using information from the Breland-Bailey papers, this paper describes the development and activities of Animal Behavior Enterprises (ABE), the Brelands' animal training business. We also review popular press coverage of the Brelands between 1947 and 1966 to investigate the level of public exposure to ABE-trained animals and to the principles and methods of operant psychology. An examination of 308 popular print articles featuring the Brelands indicates that there was public exposure of behavior analysis through the popular press coverage of ABE-trained animals. Furthermore, the expansion of operant methods to the marine mammal and bird training industries can be linked to the Brelands' mass media exposure.
