“Play it Again”: a new method for testing metacognition in animals

Putative metacognition data in animals may be explained by non-metacognition models (e.g., stimulus generalization). The primary objective of the present study was to develop a new method for testing metacognition in animals that may yield data that can be explained by metacognition but not by non-metacognition models. Next, we used the new method with rats. Rats were first presented with a brief noise duration which they would subsequently classify as short or long. Rats were sometimes forced to take an immediate duration test, forced to repeat the same duration, or had the choice to take the test or repeat the duration. Metacognition, but not an alternative non-metacognition model, predicts that accuracy on difficult durations is higher when subjects are forced to repeat the stimulus compared to trials in which the subject chose to repeat the stimulus, a pattern observed in our data. Simulation of a non-metacognition model suggests that this part of the data from rats is consistent with metacognition, but other aspects of the data are not consistent with metacognition. The current results call into question previous findings suggesting that rats have metacognitive abilities. Although a mixed pattern of data does not support metacognition in rats, we believe the introduction of the method may be valuable for testing with other species to help evaluate the comparative case for metacognition.     

Association of maternal interaction with emotional regulation in 4- and 9-month infants during the Still Face Paradigm

This study used the Still Face Paradigm to investigate the relationship of maternal interaction on infants' emotion regulation responses. Seventy infant-mother dyads were seen at 4 months and 25 of these same dyads were re-evaluated at 9 months. Maternal interactions were coded for attention seeking and contingent responding. Emotional regulation was described by infant stress reaction and overall positive affect. Results indicated that at both 4 and 9 months mothers who used more contingent responding interactions had infants who showed more positive affect. In contrast, mothers who used more attention seeking play had infants who showed less positive affect after the Still Face Paradigm. Patterns of stress reaction were reversed, as mothers who used more attention seeking play had infants with less negative affect. Implications for intervention and emotional regulation patterns over time are discussed.     

Expanding coping goodness-of-fit: religious coping, health locus of control, and depressed affect in heart failure patients

The goodness-of-fit coping hypothesis posits that problem-focused (PF) coping is particularly helpful under high controllability conditions, while emotion-focused (EF) coping is more helpful in low controllability situations. However, little research has examined whether the goodness-of-fit hypothesis applies to religious coping, a distinct set of coping resources and efforts. Further, little goodness-of-fit research has been conducted in the context of life-threatening illness. We tested coping goodness-of-fit for PF and EF as well as religious coping resources and strategies in 202 congestive heart failure (CHF) patients. Multiple regression analyses examined the extent to which each type of coping, health locus of control (HLOC) regarding their CHF, and their interactions related to subsequent depressed affect. Neither religious coping efforts nor religious resources were related to depressed affect. However, when examined in conjunction with internal HLOC, active coping and organized religious commitment were related to less depression for those higher in internal HLOC, while daily spiritual experience was related to less depression for those lower in HLOC. These results partially support the goodness-of-fit hypothesis and indicate a need to consider the perceived controllability of situations when examining the associations of religious coping resources and activities on depressive symptoms in the context of illness.     

Attributions of deviance to self and peers by Japanese and U.S. students

The author examined self-enhancement bias among 5th and 11th graders in the United States and Japan. After listening to stories describing aggressive, depressive, oppositional, and school-phobic behaviors of hypothetical peers, the participants rated the likelihood that they themselves and other students their age would act like the story protagonists. The U.S. students generally showed no greater self-enhancement tendencies than did the Japanese students; in addition, the relationships between positive and negative self-concepts and ratings of self-similarity to deviant exemplars were similar in both samples. In the depressed and oppositional stories, the 11th graders rated themselves less like the deviant characters and more different from their peers than did the 5th graders.     

Spontaneously occurring mother-infant swapping and the relationships of infants with their biological and foster mothers in a captive group of lowland gorillas (Gorilla gorilla gorilla)

The present study describes spontaneously occurring infant-mother swapping and the relationships of infants with their biological and foster mothers after swapping in a captive social group of lowland gorillas (Gorilla gorilla gorilla). After infant-swapping took place between a primiparous mother with a neonate and a multiparous mother with a 10-month-old infant, the mothers provided appropriate maternal care, including nursing, to their adopted infants, but the older infant still sought refuge with its biological mother more frequently than with its foster mother. Almost 2 years later, the younger infant who was weaned by its foster mother began nursing from its biological mother; the latter subsequently weaned her adopted infant. Thereafter, the older infant who was weaned exhibited an abnormal hair-plucking behavior. These results indicate that it was psychologically stressful for the gorilla infant to quickly transfer its attachment figure from the mother to another adult female when the mother continued to remain in the group.     

Death without God: religious struggle, death concerns, and depression in the terminally ill

ABSTRACT— Religious worldviews often provide comfort near the end of life, but they can cause distress if life circumstances are perceived as evidence of God's disfavor. This study, the first to test terror management theory (TMT) with terminally ill participants, examined the hypothesis that concerns about death mediate the relationship between religious struggle (and religious comfort) and depression in the terminally ill. Ninety-eight patients with end-stage congestive heart failure (CHF) completed measures of religious comfort, religious struggle, belief in an afterlife, concerns about death, and depression. In separate hierarchical linear regression models that controlled for degree of belief in an afterlife, death concerns fully mediated the relationships between religious struggle and depression and between religious comfort and depression. These findings suggest that religious struggle is a breakdown in the terror management system that leaves the individual vulnerable to the terror of death, and that properly functioning religious worldviews offer comfort by buffering the individual against death concerns.
