An analysis of coordinated responding of pigeons

Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a coordination contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments addressed some of these limitations by holding the schedule of reinforcement (Experiment 1: fixed ratio 1; Experiment 2; variable interval 20 s) constant across phases and between dyad members and by varying, in different conditions, the number of response keys (one to three) across which coordination could occur. Greater percentages of coordinated responding occurred under the coordinated-reinforcement phases than under independent-reinforcement phases in most conditions. The one exception during the one-key condition of Experiment 1 appeared to be a consequence of variability introduced by the independent-reinforcement phase procedure. Furthermore, coordination percentages decreased with increasing response options under both schedules. These results confirm and extend the finding that coordination contingencies control higher rates of temporally coordinated responding than independent-reinforcement contingencies do.     

Relating different perspectives on how outcomes of behavior influence behavior

Many researchers have tackled the question of how behavior is influenced by its outcomes. Some have adopted a nonmechanistic (functional) perspective that attempts to describe the influence of outcomes on behavior. Others have adopted a mechanistic (cognitive) perspective that attempts to explain the influence of outcomes on behavior. Orthogonal to this distinction, some have focused on the influence of outcomes that a behavior had in the past, whereas others also consider the influence of outcomes that a behavior might have in the future. In this article, we relate these different perspectives with the goal of reducing misunderstandings and fostering collaborations between researchers who adopt different perspectives on the common question of how behavior is influenced by its outcomes.     

Caregiver involvement in applied behavior-analytic research: A scoping review and discussion

We conducted a scoping review to characterize the role of caregiver involvement in behavior-analytic research. We reviewed eight behavioral-learning journals from 2011–2022 for works that included children or caregivers as participants and characterized caregiver involvement as passive (implications for caregivers, input, social validity) and active (implementation, caregiver behavior, training, caregiver-collected data). The review identified 228 studies, and almost all (96.1%; n = 219) involved caregivers in some capacity; 94.3% (n = 215) had passive involvement (26.8% had only passive involvement; n = 61), 69.3% (n = 158) had active involvement (1.8% had only active involvement; n = 4), and 3.9% (n = 9) had neither passive nor active involvement. Involvement generally increased over publication years. The most common types of involvement were implications for caregivers, implementation, and input; caregiver-collected data were rare. We propose considerations when engaging caregivers in research and suggest new avenues of inquiry related to caregivers' treatment objectives and social validity, treatment implementers, and caregiver-collected data.     

A comparative effectiveness trial of functional behavioral assessment methods

Clinicians report primarily using functional behavioral assessment (FBA) methods that do not include functional analyses. However, studies examining the correspondence between functional analyses and other types of FBAs have produced inconsistent results. In addition, although functional analyses are considered the gold standard, their contribution toward successful treatment compared with other FBA methods remains unclear. This comparative effectiveness study, conducted with 57 young children with autism spectrum disorder, evaluated the results of FBAs that did (n = 26) and did not (n = 31) include a functional analysis. Results of FBAs with and without functional analyses showed modest correspondence. All participants who completed functional communication training achieved successful outcomes regardless of the type of FBA conducted.     

Work attitudes,career success and health: Evidence from China

Research on the determinants and implications of career success, and in particular on how they are related to health among Chinese workers is scarce. This research explores the impact and relevance of individual attitudes of trust and organizational citizenship behavior on objective and subjective career success, and their relevance to physical and mental health. Further, we explore the moderating role of a career system on the relationships between work attitudes and career success. Using a random sample of 10,372 people in China we used multi-level linear regression methodology to explore a mediation–moderation model based on organizational theories. We found support for the impact of organizational citizenship behaviors and trust, for both objective and subjective career success as mediators of mental and physical health, and for a career system as a moderator, with significant differences emerging between workers employed in the public and private sectors. The results are important as they shed light on the relationship between work and life attitudes on outcomes of high relevance at national level. The original contribution would be of interest to policy makers at both organizational and national level.     

Organizational career growth and subsequent voice behavior: The role of affective commitment and gender

Although research has established a connection between career growth and turnover intentions, there continues to be a need to study how employee career growth contributes positively to organizations. In the present research, we studied in particular how employees' organizational career growth is related to voice behavior. Employing theories of social exchange, organization-based self-esteem, and psychological attachment, we developed six hypotheses pertinent to this relationship, including the mediating role of affective organizational commitment and the moderating effect of gender. We tested our hypotheses using data from 328 employees in Mainland China over three time periods. As we hypothesized, we found positive relationships between the three dimensions of organizational career growth and subsequent voice behavior. Our results also verified that these relationships are partially mediated by affective organizational commitment and partially moderated by gender.     

A Comparison of Interactions Among Children,Parents, and Therapists in Cognitive Behavior Therapy for Anxiety Disorders in Australia and Japan

Despite growing attention to the efficacy of culturally adapted cognitive-behavioral treatment (CBT) programs for children and adolescents, there is still little empirical and practical information available to therapists who adapt original treatment protocols to suit clients of a specific culture. The current study aimed to compare therapeutic interactions across CBT treatment delivered with two different cultural groups. We developed an observational coding system to examine behaviors exhibited by child, parent, and therapist during CBT sessions conducted in Australia and Japan for children with anxiety disorders. Our results demonstrated significant differences between the two countries with respect to the treatment readiness of children, the proportion of talking during the sessions by parents and children, therapists’ laughter, length of silence during the first session, and parent indices of accommodation. In terms of transitions over time (i.e., first to last CBT session), parents in both countries tended to talk more during the last CBT session, whereas only Australian therapists talked less over time. The proportion of silence decreased over time during the Japanese sessions, and the amount of interruptions by parents increased over time for Australian sessions. Finally, our exploratory analyses demonstrated that a number of behavioral observations were correlated with anxiety treatment outcome at posttreatment. This study suggests that interactions between a child, parent, and therapist during CBT sessions may be affected by the culture in which the CBT session occurs, which could have implications for culturally adapted CBT programs.     

Sexual activity is inversely related to women’s perceptions of the facial attractiveness of unknown men

A study was conducted to assess whether individual differences in sexual activity during the past 30 days, in particular penile–vaginal intercourse (PVI; which is associated with measures of relationship quality), are related to the perception of the facial attractiveness of unknown men. Forty-five women reported the frequency of a variety of sexual behaviors and rated the facial attractiveness and friendliness of 24 men. Women who reported more frequent orgasm from masturbation rated men as less friendly. This finding might be reflective of the more anti-social attitude associated with more frequent masturbation. The results also show that women who engaged more frequently in most kinds of sexual behavior, not only PVI, considered unknown men to be less facially attractive. That is, individuals who engage more frequently in a variety of sexual behaviors with their partner perceived unknown men as less attractive and thereby may be less susceptible to the lure of other (or if the only sexual behavior is masturbation, any) men.     

Effects of object complexity and type on the gaze behavior of children with pervasive developmental disorder

The looking behavior of children with pervasive developmental disorder (PDD) and age- and IQ-matched normal control children was studied using infrared oculography. Stimuli varying in complexity and topic were presented to test whether children with PDD have specific abnormalities in looking behavior to complex stimuli and/or to faces. All children showed more and longer fixations on the complex objects than on the simple objects, especially the complex nonsense figure, but group differences were not found. The results show no evidence for specific abnormalities in looking behavior to either faces or to complex stimuli in high functioning children with PDD.     

The Role of Strategy in Mixed-Gender Group Interactions: A Study of the Television Show “The Weakest Link”

This paper studies mixed-gender group interactions in a strategic game where group members are sequentially eliminated till a single winner takes all. Study 1 tests the hypothesis that female contestants are retained till final rounds where they are eliminated. Using observational data from the US television show The Weakest Link (20 shows), results show that females are finalists but not winners. In a laboratory study (Study 2, 67 Berkeley undergraduates), we show that this effect is attenuated when winnings are shared among finalists (versus one winner takes all) due to the reduction in competitive pressures in the context. This research was supported in part by the Junior Faculty Research Grant awarded by the University of California at Berkeley to the second author.
