Information‐Theoretic Measures Predict the Human Judgment of Rhythm Complexity

To formalize the human judgment of rhythm complexity, we used five measures from information theory and algorithmic complexity to measure the complexity of 48 artificially generated rhythmic sequences. We compared these measurements to human prediction accuracy and easiness judgments obtained from a listening experiment, in which 32 participants guessed the last beat of each sequence. We also investigated the modulating effects of musical expertise and general pattern identification ability. Entropy rate and Kolmogorov complexity were correlated with prediction accuracy, and highly correlated with easiness judgments. A logistic regression showed main effects of musical training, entropy rate, and Kolmogorov complexity, and an interaction between musical training and both entropy rate and Kolmogorov complexity. These results indicate that information‐theoretic concepts capture some salient features of the human judgment of rhythm complexity, and they confirm the influence of musical expertise on complexity judgments.     

How communication increases interpersonal cooperation in mixed-motive situations

Evidence from two experiments indicates that task-related communication promotes cooperation in mixed-motive situations by activating interpersonal norms related to fairness and trust. In Experiment 1, task-related communication increased cooperation between individuals in a three-choice prisoner’s dilemma game (PDG-Alt) but task-unrelated communication did not. In Experiment 2, cooperation was increased both by sending a task-related message to one’s counterpart and receiving a cooperative task-related message from one’s counterpart. Mediation analyses revealed that task-related communication increased cooperation by activating fairness and trust norms (Experiments 1 and 2). Specifically, whereas sending (relative to receiving) a task-related message increased cooperation by activating fairness norms, receiving (relative to sending) a task-related message increased cooperation by activating trust norms (Experiment 2).     

What do conscientious people do? Development and validation of the Behavioral Indicators of Conscientiousness (BIC)

Typical assessments of personality traits collapse behaviors, thoughts, and feelings into a single measure without distinguishing between these different manifestations. To address this lack of specification, the current study develops and validates a measure that assesses a number of broad behaviors associated with the personality trait of conscientiousness (the Behavioral Indicators of Conscientiousness; BIC). Findings suggest that the lower-order structure of conscientious behaviors is mostly similar to the lower-order structure in extant trait measures. Furthermore, a daily diary method was used to validate the BIC against frequency counts of conscientious behavior. Overall, the results identify specific behaviors that conscientious individuals tend to perform and highlight possible advantages of this approach over broad trait assessment.     

CLASSIC INVARIANTISM, RELEVANCE AND WARRANTED ASSERTABILITY MANŒVRES

Jessica Brown contends that Keith DeRose's latest argument for contextualism fails to rule out contextualism's chief rival, namely, classic invariantism. Still, even if their position has not been ruled out, classic invariantists must offer considerations in favour of their position if they are to show that it is superior to contextualism. Brown defends classic invariantism with a warranted assertability manœvre that utilizes a linguistic pragmatic principle of relevance. I argue, however, that this manœvre is not as effective as it might be. I propose a different warranted assertability manœvre, which utilizes a pragmatic principle of strength, affords a more successful defence of classic invariantism, and helps to establish that classic invariantism is superior to contextualism.

How nostalgia infuses life with meaning: From social connectedness to self-continuity

Nostalgia increases meaning in life (MIL), but how so? In four experiments—using varied operationalizations of nostalgia, diverse populations, and complementary methodologies—we identified a serial process. We hypothesized and found, in Experiment 1, that self-continuity boosts MIL. We hypothesized and found, in Experiment 2, that nostalgia increases MIL through self-continuity. Finally, we hypothesized and found, in Experiments 3–4, that nostalgia fosters social connectedness, which plausibly heightens self-continuity, which in turn strengthens MIL. The findings clarify an intricate pathway through which nostalgia renders life more meaningful.     

Child and Family Team Meeting Characteristics and Outcomes in a Statewide System of Care

Systems of care (SOC) have relied on the wraparound care process to individualize community‐based services for children and youth with serious emotional and behavioral difficulties. A core element of wraparound care is Child and Family Team meetings (CFTs), which are designed to give youth and families a leadership role in developing and guiding their plan of care. The National Wraparound Initiative (NWI) has identified Practice Standards regarding CFT implementation. This study examined CFT characteristics and the association between those characteristics and youth and family outcomes in a statewide SOC. Participants were 363 youth (M_age = 10.89, SD = 3.72) and their caregivers. Families completed measures of youth and caregiver functioning and symptoms at enrollment and 6‐month follow‐up. Care coordinators completed a survey assessing CFT implementation and characteristics following each meeting. Multiple regression analyses were used to examine the relationship between CFT characteristics and youth and caregiver outcomes. Results indicated that a higher number of CFTs was associated with poorer outcomes, while a higher percentage of natural supports at meetings was associated with better youth outcomes. Number of days to the first CFT was associated with greater caregiver strain. Implications for CFT implementation within wraparound are discussed.     

Psychological threat and extrinsic goal striving

Although people generally endorse intrinsic goals for growth, intimacy, and community more than extrinsic goals for money, appearance, and popularity, people sometimes over-emphasize extrinsic goals, to the potential detriment of their well-being. When and why does this occur? Results from three experimental studies show that psychological threat increases the priority that people give to extrinsic compared to intrinsic goals. This was found in the case of existential threat (Study 1), economic threat (Studies 2), and interpersonal threat (Study 3). Discussion focuses on the possible reasons why threat breeds extrinsic orientations.
