Evaluation of third-party reciprocity by squirrel monkeys (<Emphasis Type="Italic">Saimiri sciureus</Emphasis>) and the question of mechanisms

Social evaluation during third-party interactions emerges early in human ontogeny, and it has been shown in adult capuchin monkeys who witness violations of reciprocity in object exchanges: Monkeys were less inclined to accept food from humans who refused to reciprocate with another human. A recent study reporting similar evidence in marmoset monkeys raised the possibility that such evaluations might be based on species’ inherent cooperativeness. We tested a species not renowned for cooperativeness—squirrel monkeys—using the procedure used with marmosets and found a similar result. This finding rules out any crucial role for cooperative tendencies in monkeys’ responses to unfair exchanges. We then tested squirrel monkeys using procedures more similar to those used in the original study with capuchins. Squirrel monkeys again accepted food less frequently from non-reciprocators, but unlike capuchins, they also strongly preferred reciprocators. We conclude that neither squirrel monkeys nor marmoset monkeys engaged in emotional bookkeeping of the type that probably underlies social evaluation in capuchin monkeys; instead, they employed one or more simple behavioral rules. Further comparative studies are required to clarify the mechanisms underlying social evaluation processes across species.     

Color and intensity discrimination in <Emphasis Type="Italic">Xenopus laevis</Emphasis> tadpoles

Investigations into the physiology of Xenopus laevis have the potential to greatly accelerate biomedical research, especially concerning neural plasticity and sensory systems, but are limited by the lack of available information on behavioral learning in this species. Here, we attempt to lay the foundations for a behavioral assay in Xenopus that can be used in conjunction with biological manipulations. We tested cohorts of Xenopus tadpoles across four light-mediated active-avoidance experiments, using either wavelength or intensity as the salient discriminative cue. In the wavelength task, we determine a baseline learning rate and characterize retention of learning, identifying active extinction effects as far more potent than the passage of time in the loss of behavior. In the intensity task, we examine the effects of varying differences between the discriminative stimuli on acquisition and extinction and identify a critical range of intensity differences where learning changes. The results of our experiments demonstrate that Xenopus is a tractable model organism for cognitive research and can learn a variety of associative tasks in the laboratory settings. These data reveal new aspects of the Xenopus larval visual processing system and facilitate future research between cognitive methods and biological/chemical manipulations to study mechanisms of brain structure and function.     

A novel tool-use mode in animals: New Caledonian crows insert tools to transport objects

New Caledonian crows (Corvus moneduloides) rely heavily on a range of tools to extract prey. They manufacture novel tools, save tools for later use, and have morphological features that facilitate tool use. We report six observations, in two individuals, of a novel tool-use mode not previously reported in non-human animals. Insert-and-transport tool use involves inserting a stick into an object and then moving away, thereby transporting both object and tool. All transported objects were non-food objects. One subject used a stick to transport an object that was too large to be handled by beak, which suggests the tool facilitated object control. The function in the other cases is unclear but seems to be an expression of play or exploration. Further studies should investigate whether it is adaptive in the wild and to what extent crows can flexibly apply the behaviour in experimental settings when purposive transportation of objects is advantageous.     

The effect of filled pauses on the processing of the surface form and the establishment of causal connections during the comprehension of spoken expository discourse

The purpose of this study was to examine the effect of filled pauses (uh) on the verification of words and the establishment of causal connections during the comprehension of spoken expository discourse. With this aim, we asked Spanish-speaking students to listen to excerpts of interviews with writers, and to perform a word-verification task and a question-answering task on causal connectivity. There were two versions of the excerpts: filled pause present and filled pause absent. Results indicated that filled pauses increased verification times for words that preceded them, but did not make a difference on response times to questions on causal connectivity. The results suggest that, as signals of delay, filled pauses create a break with surface information, but they do not have the same effect on the establishment of meaningful connections.     

The relationship between action anticipation and emotion recognition in athletes of open skill sports

Action anticipation plays an important role in the successful performance of open skill sports, such as ball and combat sports. Evidence has shown that elite athletes of open sports excel in action anticipation. Most studies have targeted ball sports and agreed that information on body mechanics is one of the key determinants for successful action anticipation in open sports. However, less is known about combat sports, and whether facial emotions have an influence on athletes’ action anticipation skill. It has been suggested that the understanding of intention in combat sports relies heavily on emotional context. Based on this suggestion, the present study compared the action anticipation performances of taekwondo athletes, weightlifting athletes, and non-athletes and then correlated these with their performances of emotion recognition. This study primarily found that accurate action anticipation does not necessarily rely on the dynamic information of movement, and that action anticipation performance is correlated with that of emotion recognition in taekwondo athletes, but not in weightlifting athletes. Our results suggest that the recognition of facial emotions plays a role in the action prediction in such combat sports as taekwondo.     

Racial–Ethnic Protective Factors and Mechanisms in Psychosocial Prevention and Intervention Programs for Black Youth

Extending previous reviews related to cultural responsiveness in the treatment of ethnic minority youth, the current review provides a critical assessment and synthesis of both basic and applied research on the integration of three racial–ethnic protective factors (racial identity, racial socialization, Africentric worldview) in psychosocial prevention and intervention programs for Black children and adolescents. Seventeen programs meeting inclusion and exclusion criteria were evaluated for the extent to which racial–ethnic protective factors and related mechanisms were integrated, applied, and tested in such programs. A systematic assessment of these programs revealed that several prevention and intervention programs drew upon the three factors, particularly Africentric worldview. In addition, a number of studies hypothesized and assessed mechanisms, both those previously identified in conceptual literature and those that emerged from the interventions themselves. A set of recommendations encouraging the implementation of these factors into future prevention and intervention programs, examples of how clinicians can infuse these factors into psychotherapy, and areas for future research are discussed.     

Distilling Common History and Practice Elements to Inform Dissemination: Hanf-Model BPT Programs as an Example

There is a shift in evidence-based practice toward an understanding of the treatment elements that characterize empirically supported interventions in general and the core components of specific approaches in particular. The evidence base for behavioral parent training (BPT) and the standard of care for early-onset disruptive behavior disorders (oppositional defiant disorder and conduct disorder), which frequently co-occur with attention deficit hyperactivity disorder, are well established, yet an ahistorical, program-specific lens tells little regarding how leaders, University of Oregon Medical School, shaped the common practice elements of contemporary evidence-based BPT. Accordingly, this review summarizes the formative work of Hanf, as well as the core elements, evolution, and extensions of her work, represented in Community Parent Education (COPE; (Cunningham et al. in J Child Psychol Psychiatry 36:1141–1159, 1995; Cunningham et al. in COPE, the community parent education program: large group community-based workshops for parents of 3- to 18-year-olds, COPE Works, Hamilton, 2009), Defiant Children (DC; (Barkley in Defiant children: a clinician’s manual for assessment and parent training, Guilford Press, New York, 1987; Barkley in Defiant children: a clinician’s manual for assessment and parent training, Guilford Press, New York, 2013), Helping the Noncompliant Child (HNC; Forehand and McMahon in Helping the noncompliant child: a clinician’s guide to parent training, Guilford Press, New York, 1981; McMahon and Forehand in Helping the noncompliant child: family-based treatment for oppositional behavior, 2nd ed., Guilford Press, New York, 2003), Parent–child interaction therapy (PCIT; Eyberg and Robinson in J Clin Child Adolesc Psychol 11:130–137, 1982. doi:10.1080/15374418209533076; Eyberg in Child Fam Behav Ther 10:33–46, 1988; Eyberg and Funderburk in Parent–child interaction therapy protocol, PCIT International, Gainesville, 2011), and the Incredible Years (IY; (Webster-Stratton in Behav Ther 12:634–642, 1981. doi:10.1016/S0005-7894(81)80135-9; Webster-Stratton in J Pediatr Psychol 7:279–294, 1982. doi:10.1093/jpepsy/7.3.279; Webster-Stratton in The incredible years: parents and children series. Leader’s guide: preschool version of BASIC (ages 3–6 years, The Incredible Years, Seattle, 2008). Our goal is not to provide an exhaustive review of the evidence base for the Hanf-Model programs, rather our intention is to provide a template of sorts from which agencies and clinicians can make informed choices about how and why they are using one program versus another, as well as how to make inform flexible use one program or combination of practice elements across programs, to best meet the needs of child clients and their families. Clinical implications and directions for future work are discussed.     

Black Church Leaders’ Attitudes About Mental Health Services: Role of Racial Discrimination

Black church leaders are often first responders to mental health issues in the Black community, yet few researchers have examined their attitudes about seeking outside mental health services. In order to fill this gap, we surveyed 112 church leaders in a northeastern urban Baptist Black mega-church (22 associate pastors, 34 deacons, and 56 congregation care givers) using The National Survey of American Life. Findings suggest church leaders more often relied on the church community and alternative health services, leaders who attended church more often tended to report not receiving any outside mental health treatment, the closer church leaders felt to all Black people, the less satisfied they were with help received from formal mental health services, and leaders who experienced more racial discrimination tended to report worse overall mental and physical health. Clinical providers and Black churches should develop collaborative partnerships to better meet the needs of this community.     

Readiness for Change: Involving the Family with Adolescents in Residential Settings

Adolescence is a pivotal time in human development and can be a challenging time for individuals to learn to regulate emotions, while also balancing biopsychosocial changes. The family plays a key role in an adolescent’s development. Thus, it is imperative for families to remain involved when adolescents are in residential treatment for emotional or behavioral issues. In this paper, we explore the benefits of, and methods for, increasing the identified patient’s (i.e., the adolescent’s) and the family’s readiness for change. The process of increasing family engagement in residential treatment is considered through the lens of the Stages of Change model. Barriers practitioners may face with adolescents and their families are also addressed.     

Common Factors Come Alive: Practical Strategies for Implementing Common Factors in MFT Training

Presently, MFT training programs teach MFT models in a way that emphasizes differences over similarities (Karam et al. in J Marital Fam Ther, 2015. doi: 10.1111/jmft.12096; Sprenkle and Blow in J Marital Fam Ther 30:113–129, 2004a. doi: 10.1111/j.1752-0606.2004.tb01228.x, in J Marital Fam Ther 30:151–157, b. doi: 10.1111/j.1752-0606.2004.tb01230.x; Sprenkle et al. in Common factors in couple and family therapy: the overlooked foundation for effective practice. Guilford Press, New York, 2009). Although teaching a variety of models and their distinctiveness is vital, doing so may create a competitive rather than integrative relationship between models (Karam et al. 2015). While Karam et al. 2015 encourage the inclusion of common factors in MFT training, we expand their justification for the importance of doing so We also explain conceptual and practical ways to include common factors in MFT training. Common factors instruction can fulfill multiple purposes: (a) create a sense of cohesiveness for programs which need to teach breadth of topics that can seem unrelated, (b) help prepare practitioners who need to learn many models well but will likely adopt an integrative approach, (c) align with basic skills training, (d) align with process research, and (e) enhance the richness of individual models. For each of these purposes, we provide an example of a classroom activity. We conclude with a unifying example of how one student may learn the common-factors perspective and weave it into her reflective practices as an MFT student.
