Introduction: Using Techniques via the Therapeutic Relationship

In this work, we have the opportunity to hear people’s most private concerns, worries, distress, and share in their hopes, aspirations, and dreams for the future. The work involved in the practice of cognitive behavior therapy; our knowledge, theories, techniques, and strategies are practically useless if we are unable to relate to our clients. Relational attributes were incorporated as part of the defining features essential to therapeutic change in the seminal guide for cognitive therapy (A. T. Beck, Rush, Shaw, & Emery, 1979). Conceptualizations of “collaboration” and “empiricism” have since been misconstrued with the construct of the working alliance in the past, although both have unique distinctions and implications for practice. This article presents an introduction to a special series in Cognitive and Behavioral Practice, which illustrates the vital role of collaborative empiricism within culturally responsive CBT, through the structure of the therapy session, cognitive case conceptualization, self-monitoring, interventions focused on cognitive change, and exposure to emotions and situations. We invite you to join with us in considering the extent to which the ideas shared herein are relevant for your work with clients. It is also our hope that you will consider evaluating and incorporating the utility of these ideas in your therapy.     

Sex-role expectations changes by fathers for their sons

One hundred nineteen white father-son pairs served as subjects in an effort to examine the impact on sex-role redefinitions of boys' behavior as a result of shifting cultural attitudes toward androgyny. Two major questions were addressed: a) Do fathers' general sex-role beliefs influence their attitudes about sex roles they would like their sons to hold? and b) Do fathers' desires for the sex role attitudes they would like their sons to hold influence the attitudes their sons actually hold? A strong, positive relationship between fathers' and sons' sex-role beliefs and expectations emerged, especially among fathers of adolescent boys. The results are discussed in terms of the fathers' role in shaping their sons' beliefs.     

Effects of Self-Monitoring on On-Task Behaviors of At-Risk Middle School Students

The purposes of this study were to evaluate the effects of self-monitoring on increasing the on-task behaviors of four at-risk middle school students, and to examine its indirect effects on academic performance. Additionally, we attempted to develop and validate cost- and time-efficient procedures that typical classroom teachers could use. The data from a multiple baseline design across three academic settings, replicated with four students, revealed immediate increases in on-task behavior as each student began to self-monitor in each sequential setting. The data also revealed slightly higher levels of academic performance and, in most instances, gradually accelerating trends. These findings suggest that self-monitoring is a cost- and time-efficient procedure that classroom teachers can use to teach at-risk students to manage their own behaviors.     

An own-age bias in mixed- and pure-list presentations: No evidence for the social-cognitive account

The own-age bias (OAB) is suggested to be caused by perceptual-expertise and/or social-cognitive mechanisms. Bryce and Dodson (2013, Psychology and Aging, 28, 87, Exp 2) provided support for the social-cognitive account, demonstrating an OAB for participants who encountered a mixed-list of own- and other-age faces, but not for participants who encountered a pure-list of only own- or other-age faces. They proposed that own-age/other-age categorization, and the resulting OAB, only emerge when age is made salient in the mixed-list condition. Our study aimed to replicate this finding using methods typically used to investigate the OAB to examine their robustness and contribution to our understanding of how the OAB forms. Across three experiments that removed theoretically unimportant components of the original paradigm, varied face sex, and included background scenes, the OAB emerged under both mixed-list and pure-list conditions. These results are more consistent with a perceptual-expertise than social-cognitive account of the OAB, but may suggest that manipulating age salience using mixed-list and pure-list presentations is not sufficient to alter categorization processes.     

Defining and Measuring Mechanisms of Change in Psychological Therapies: The Path Not Taken

Metcalf and Dimidjian (this issue) have provided an important review of the current evidence base for mindfulness‐based cognitive therapy (MBCT) and presented a helpful summary of the proposed mechanisms of change. It is necessary to engage in a continuous dialogue regarding the evidence base for change mechanisms, and the article by Metcalf and Dimidjian highlights an important barrier of concern to the field of treatment outcome research. The present commentary aims to expand the discussion regarding the definition, measurement, and evaluation of “mechanisms of change.” Using MBCT as an example, this commentary addresses the ambiguity surrounding the definition and operationalisation of these mechanisms in research on psychological therapies and how the method of measurement may impact the results obtained in clinical trials. It is argued that a potentially fruitful avenue of future research would involve investigation of techniques, important client‐therapeutic processes, and mechanisms in a single study in order to comprehensively evaluate how change occurs.     

Ratio-dependent quantity discrimination in quorum sensing ants

To optimise behaviour, organisms require information on the quantity of various components of their environment, and the ability of animals to discriminate quantity has been a subject of considerable recent interest. This body of research hints at generalised mechanisms of quantity discrimination in vertebrates, but data on invertebrates are still relatively scarce. In this study, I present data on the quantification abilities of an invertebrate in a novel context: quorum sensing. Quorum sensing generates a behavioural response in group-living animals once a threshold number of individuals, a ‘quorum’, is detected performing some key action. This process forms the basis for consensus decision-making in many species and allows group-living organisms to decide among mutually exclusive alternatives without compromising group integrity. To determine when a quorum is achieved, individuals must assess the number of group members performing the key action. Social insects employ quorum decisions to decide among potential nest sites when searching for a new home. In the Japanese ant, Myrmecina nipponica, quorum thresholds increase with colony size, providing an opportunity to assess the accuracy of quantity discrimination at different stimulus magnitudes. In this study, I demonstrate that the variation in individual quorum thresholds around the mean increases with increasing colony size. This indicates that the quantity discrimination ability of ants decreases with stimulus magnitude, and thus exhibits ratio dependence in the manner of Weber’s Law. This may have implications for the accuracy of consensus decision-making and other collective actions in a range of group-living organisms.     

Stable middle-aged face recognition: No moderation of the own-age bias across contexts

The own-age bias (OAB) has been proposed to be caused by perceptual expertise and/or social-cognitive mechanisms. Investigations into the role of social cognition have, however, yielded mixed results. One reason for this might be the tendency for research to focus on the OAB in young adults, between young and older adult faces where other-age individuation experience is low. To explore whether social-cognitive manipulations may be successful when observers have sufficient other-age individuation experience, we examined biases involving middle-aged other-age faces and the influence of a context manipulation. Across four experiments, young adult participants were presented with middle-aged faces alongside young or older adult faces to remember. We predicted that in contexts where middle-aged faces were positioned as other-age faces (alongside young adult faces), recognition performance would be worse than when they were positioned as relative own-age faces (alongside older adult faces). However, the context manipulations did not moderate middle age face recognition. This suggests that past findings that context does not change other-age face recognition holds for other-age faces for which observers have higher individuation experience. These findings are consistent with a perceptual expertise account of the OAB but more investigation of the generality of these results is required.     

Vertical and leg stiffness and stretch-shortening cycle changes across maturation during maximal sprint running

The purpose of this study was to investigate whether vertical and leg stiffness, and stretch-shortening cycle (SSC) ability differed in developing athletes of various maturity status during maximal sprint running. Seventy-four male participants between 8 and 16 years of age were categorized into pre-, mid- or post-peak height velocity (PHV) and sprinted for 30 meters on a non-motorized treadmill. Dimensionless vertical stiffness increased significantly (p < .05) from pre-, to mid- and post-PHV state, while dimensionless leg stiffness was significantly higher in post- compared to mid- (18.4%) and pre-PHV participants (44.5%). Eccentric power was significantly lower in pre- compared to the mid- and post-PHV participants. Concentric power increased from pre- to mid- and post-PHV state. An analysis of covariance revealed no significant differences between all groups in dimensionless vertical and leg stiffness, eccentric and concentric time and power when controlling for years from PHV (maturation). Eccentric or concentric power, were found to be the best predictors of maximum velocity across all maturation groups (r² = .37–.68). It seems that maturation affects the ability to absorb and produce power and furthermore these variables are important predictors of maximal running velocity.
