Pilgrims sailing the Titanic: Plausibility effects on memory for misinformation

People rely on information they read even when it is inaccurate (Marsh, Meade, & Roediger, Journal of Memory and Language 49:519–536, 2003), but how ubiquitous is this phenomenon? In two experiments, we investigated whether this tendency to encode and rely on inaccuracies from text might be influenced by the plausibility of misinformation. In Experiment 1, we presented stories containing inaccurate plausible statements (e.g., “The Pilgrims’ ship was the Godspeed”), inaccurate implausible statements (e.g., . . . the Titanic), or accurate statements (e.g., . . . the Mayflower). On a subsequent test of general knowledge, participants relied significantly less on implausible than on plausible inaccuracies from the texts but continued to rely on accurate information. In Experiment 2, we replicated these results with the addition of a think-aloud procedure to elicit information about readers’ noticing and evaluative processes for plausible and implausible misinformation. Participants indicated more skepticism and less acceptance of implausible than of plausible inaccuracies. In contrast, they often failed to notice, completely ignored, and at times even explicitly accepted the misinformation provided by plausible lures. These results offer insight into the conditions under which reliance on inaccurate information occurs and suggest potential mechanisms that may underlie reported misinformation effects.     

Family Belongingness,Gang Friendships,and Psychological Distress in Adolescent Achievement

The authors investigated connections among social, psychological, and academic functioning of ethnically diverse urban youth. Participants included 310 seventh graders (mean age = 12.10 years) from an ethnically diverse middle school in which no ethnic group was a majority. Social engagements with family and gang members were predictive of academic achievement in the expected directions, with psychological distress mediating the effects of these social engagements on academic achievement. Implications for counselors’ work with ethnically diverse urban youth are discussed.     

Does youth psychotherapy improve academically related outcomes? A meta-analysis

To better understand the impact of psychotherapy on youth academic performance, the authors located and examined 83 studies of youth psychotherapy that contained 102 treatment comparisons. Results revealed a d = 0.46 overall effect size, with a d = 0.50 effect size for mental health outcomes, and a d = 0.38 effect size for academically related outcomes. Academically related outcomes were further categorized into teacher-rated classroom behavior (d = 0.26), academic achievement (d = 0.36), environmentally related outcomes (d = 0.26), and self-reported academically related outcomes (d = 0.59). Each of these effect sizes differed significantly from zero, and the 4 academically related categories were homogeneous. Participant racial and ethnic diversity and age were explored as moderators. The results point to psychotherapy benefiting student academics, regardless of age. Ethnically diverse participant groups in the studies fared better academically than did nondiverse groups. Implications discussed include counseling psychologists maintaining a holistic view of youth and of working more closely with educators.     

Dexamethasone Does Not Prevent Seven-Day ADX-Induced Apoptosis in the Dentate Gyrus of the Rat Hippocampus

Long-term adrenalectomy (ADX) is known to result in apoptosis within the dentate gyrus of the rat hippocampus. While the underlying mechanism is still unclear, adrenal steroids appear to play a pivotal role in granule cell survival, as administration of the mineralocorticoid receptor (MR) agonists, corticosterone and aldosterone, to ADX rats results in protection against the ADX-induced effect. The consequence of administration of the glucocorticoid receptor (GR) agonists, dexamethasone and RU28362, however, is less clear, and either complete or only partial protection for the ADX animal has been reported. This study investigated further the role played by GR in the degenerative process. After establishing the characteristics of seven-day ADX-induced apoptosis in the young male Wistar rat, the effect of chronically-implanted, subcutaneous pellets containing various doses of dexamethasone and corticosterone, on ADX-induced apoptosis was studied. Both high and low doses of corticosterone were found to be protective. In contrast to some other studies, however, neither dose of dexamethasone had any obvious protective effect and rather seemed to increase apoptosis in dentate gyrus of intact animals. Intracerebroventricular infusion of dexamethasone for seven days was also found to be ineffective in preventing apoptosis, demonstrating that it is occupation of MR, rather than GR, which is crucial to dentate gyrus granule cell survival.     

“I'm prepared for this moment”: The role of mindfulness in the psychosocial health of women of color

This study utilized a phenomenological approach to explore how women of color (N = 7) engage in mindfulness practices to improve their psychosocial well-being, specifically as it relates to identity development and belongingness. Five themes emerged: awareness of mind–body connection, resilience in the face of discrimination, empathic perspective-taking, awareness of internalized biases, and global sense of belonging. Implications for counselors and future research are discussed.     

Anticipating who will say what: The influence of speaker-specific memory associations on reference resolution

Some accounts of common ground assume that successful communication requires detailed consideration of others’ knowledge. In two studies, we provide evidence for an alternative account that views common ground as being mediated in part through domain-general memory mechanisms. On each trial, participants heard prerecorded instructions from one of two speakers indicating which of two displayed pictures to select. During an initial association phase, each speaker repeatedly referred to different sets of pictures. In Experiment 1, we contrasted a “between-speaker mapping” condition, in which each speaker referred to only one picture from critical item pairs (e.g., the cat drinking milk vs. the cat sitting up), and a “within-speaker mapping” condition, in which each speaker referred to both pictures within each pair, although item categories differed across speakers. On subsequent test trials, we recorded participants' eye fixations to critical displays that included both items from a category pair. Prior to the linguistic point of disambiguation, participants in the between-speaker mapping condition were more likely to fixate on the picture previously described by the current speaker, suggesting that knowledge associated with the speaker was prompting expectations for which picture would be the intended target. In Experiment 2, we used two prerecorded speakers of the same gender to strengthen the claim that the relevant implicit memory associations are speaker-specific. These results demonstrate how domain-general memory associations can be an important constraint upon language use.
