Father-adolescent relationships and the role of genotype-environment correlation.

This study uses 2 samples of adolescents and parents--the child-based Nonshared Environment in Adolescent Development project (NEAD; D. Reiss, J. M. Neiderhiser, E. Hetherington, & R. Plomin, 2000; N = 395 families) and the parent-based Twin and Offspring Study in Sweden (TOSS; N = 909 twin family pairs)--to investigate passive and evocative genotype-environment correlation (rGE) on fathering. Both samples used the same measures of positivity, negativity, control, and monitoring. A previous report examining mothering found evidence for passive rGE for positivity and monitoring, and evocative rGE for negativity and control, although both types of rGE were suggested in many cases. The current report focuses on fathering. Father reports of positivity and control are influenced by evocative rGE, whereas father reports of negativity and monitoring are influenced by both passive and evocative rGE. Adolescent reports of father's positivity and negativity were influenced by both evocative and passive rGE, and control and monitoring by passive rGE. The most notable difference in findings for fathers and mothers is for positivity and the presence of rGE for father's control and monitoring. These findings and their implications are discussed.     

Navigating two-dimensional mazes: chimpanzees (Pan troglodytes) and capuchins (Cebus apella sp.) profit from experience differently

We examined whether navigation is impacted by experience in two species of nonhuman primates. Five chimpanzees (Pan troglodytes) and seven capuchin monkeys (Cebus apella) navigated a cursor, using a joystick, through two-dimensional mazes presented on a computer monitor. Subjects completed 192 mazes, each one time. Each maze contained one to five choices, and in up to three of these choices, the correct path required moving the cursor away from the Euclidean direction toward the goal. Some subjects completed these mazes in a random order (Random group); others in a fixed order by ascending number of choices and ascending number of turns away from goal (Ordered group). Chimpanzees in both groups performed equivalently, demonstrated fewer errors and a higher rate of self-correcting errors with increasing experience at solving the mazes, and made significantly fewer errors than capuchin monkeys. Capuchins were more sensitive to the mode of presentation than chimpanzees; monkeys in the Ordered group made fewer errors than monkeys in the Random group. However, capuchins’ performance across testing changed little, and they remained particularly susceptible to making errors when the correct path required moving away from the goal. Thus, these two species responded differently to the same spatial challenges and same learning contexts. The findings indicate that chimpanzees have a strong advantage in this task compared to capuchins, no matter how the task is presented. We suggest that differences between the species in the dynamic organization of attention and motor processes contribute to their differences in performance on this task, and predict similar differences in other tasks requiring, as this one does, sustained attention to a dynamic visual display and self-produced movements variably towards and away from a goal.     

Self‐Improvement

This article approaches the topic of improvement from a self‐evaluation perspective, namely the interplay between the self‐improvement motive and social or evaluative feedback. The self‐improvement motive is reflected in conscious desire. It is also reflected in preferences for continuous upward feedback trajectories, upward comparison feedback, and feedback that may be self‐threatening in the present but is likely to be useful in the future. The last type of feedback preference is stronger following a resource‐bolstering experience (e.g., good mood, success feedback, self‐affirmation). Moreover, both direct and indirect activation of the self‐improvement motive facilitates recall of improvement‐oriented feedback. Such feedback is associated with increased satisfaction or positive affect, a pattern qualified by individual differences (e.g., self‐esteem, self‐theories). Finally, improvement‐oriented feedback yields better performance, a pattern also qualified by individual differences (e.g., self‐enhancement, self‐appraisal) as well as feedback attributes (gradual versus sudden). This territory‐mapping review will hopefully prove useful to future theorizing and research.     

Typologies of Alcohol Dependence. From Jellinek to Genetics and Beyond

The goal of typology research is to identify subtypes of alcohol dependent (AD) patients sharing fundamental characteristics and try to match each subtype, with the most precise treatment strategy. This review provides a comprehensive history of the literature on alcohol dependent subtypes starting from the earliest attempt made by Jellinek. The binary models identified most closely with Cloninger and Babor as well as the successively more complex classifications are discussed. Typology classification potentially useful in guiding the treatment of AD patients, especially in the case of the serotonergic medications. Contrasting data suggests that other factors could influence the response to a medication and/or that more complex typologies should be identified. In summary, typology models may assist in the ascertainment criteria for clinical trials performed in behavioral and pharmacotherapeutic interventions. Greater emphasis, however, must be made to more clearly delineate this field of research, while moving toward more standardized typologies.     

EQUIVALENCE CLASS FORMATION IN A TRACE STIMULUS PAIRING TWO‐RESPONSE FORMAT: EFFECTS OF RESPONSE LABELS AND PRIOR PROGRAMMED TRANSITIVITY INDUCTION

Three experiments identified factors that did and did not enhance the formation of two‐node four‐member equivalence classes when training and testing were conducted with trials presented in a trace stimulus pairing two‐response (SP2R) format. All trials contained two separately presented stimuli. Half of the trials, called within‐class trials, contained stimuli from the same class while the other half, called cross class trials, contained stimuli from different classes. On within class trials, making a YES response was correct and making a NO response was wrong. On cross class trials, making a NO response was correct and making a YES response was wrong. In Experiment 1, similar intermediate percentages of participants (about 50%) formed classes, regardless of whether the responses were labeled YES and NO or SAME and DIFF. Response labeling thus did not influence class formation. Regardless of response labels, failures of class formation were primarily due to failure of class‐indicative responding produced by within‐class transitivity probes. In Experiment 2, only 50% of participants formed classes without prior training, as in Experiment 1, but 100% of participants formed equivalence classes after the establishment of a generalized transitivity repertoire by use of a programmed transitivity induction protocol. Experiment 3 examined two components of the programmed transitivity induction protocol and found that the exclusion of AC trials had no effect on the percentage of participants who formed equivalence classes, while presenting the stimulus sets in randomized order interfered with equivalence class formation. A further analysis found that a number of stimulus control topographies differentiated between individuals who did and did not form equivalence classes. In general, then, these experiments demonstrate that equivalence classes can be formed reliably when training and testing are conducted in an SP2R format, supporting the view that equivalence class formation can account for the development of conceptual categories in natural settings.     

ACT in Context: An Exploration of Experiential Acceptance

Experiential acceptance, which involves “having,” or “allowing” private experiences, has recently gained much attention in the cognitive-behavioral literature. Acceptance, however, may be considered a common factor among psychotherapeutic traditions. The purposes of this paper are to examine the historical roots of acceptance and to discuss the forms of and theoretical rationales for which the concept of acceptance has been recently introduced into the cognitive-behavioral literature, with an emphasis on acceptance and commitment therapy (ACT; Hayes, Strosahl, & Wilson, 1999). It is hoped that clarification of the theoretical basis underlying acceptance-based approaches, as well as a comparison of various forms of psychotherapy with regard to their emphasis on acceptance, will promote heightened understanding and stimulate more rigorous exploration of treatment efficacy.     

Do motivational interviewing behaviors predict reductions in partner aggression for men and women?

Motivational interviewing is a directive, non-confrontational intervention to promote behavior change. The current study examined therapist behaviors during a successful brief motivational interviewing intervention for physically aggressive college dating couples (Woodin & O'Leary, 2010). Forty-five minute motivational interviews with each partner were videotaped and coded using the Motivational Interviewing Treatment Integrity scale (MITI; Moyers, Martin, Manuel, & Miller, 2003). Hierarchical modeling analyses demonstrated that therapist behaviors consistent with motivational interviewing competency predicted significantly greater reductions in physical aggression perpetration following the intervention. Specifically, greater reflection to question ratios by the therapists predicted reductions in aggression for both men and women, greater percentages of open versus closed questions predicted aggression reductions for women, and there was a trend for greater levels of global therapist empathy to predict aggression reductions for women. These findings provide evidence that motivational interviewing seems to have an effect on behavior change through therapist behaviors consistent with the theoretical underpinnings of motivational interviewing.
