The behaviour style observation system for young children predicts teacher‐reported externalizing behaviour in middle childhood

The Behaviour Style Observation System for Young Children (BSOS) was used to predict preschool‐aged children's externalizing and internalizing behaviour problems in middle childhood, 3–5 years after the initial assessment. This observational measurement tool was designed to sample and assess young children's disruptive, non‐compliant, and unresponsive behaviour, during a brief (11 min) observation in the child's home. In the current study, the BSOS was used to predict parent and teacher ratings of child behaviour problems after school entry in a longitudinal sample (N=81) of at‐risk children at time 2. The BSOS predicted teacher‐reported externalizing problems at time 2. In contrast, parent reports of behaviour problems, although correlated with repeated parent reports at time 2, were not significantly predictive of teacher‐reported behaviour problems at school age. The BSOS was not associated with either parent or teacher reports of internalizing problems. These findings emphasize the importance and utility of using observational measures when examining the continuity of behaviour problems in young children over time.

Anxiety mediates the effect of acute stress on working memory performance when cortisol levels are high: a moderated mediation analysis

Background: Anxiety is an aversive emotional state characterized by perceived uncontrollability and hypervigilance to threat that can frequently cause disruptions in higher-order cognitive processes like working memory. The attentional control theory (ACT) predicts that anxiety negatively affects the working memory system. Design: This study tested the association between anxiety and working memory after the addition of stress and measured the glucocorticoid, cortisol. To better understand this relationship, we utilized a moderated mediation model. Methods: Undergraduate students from a public university (N = 103) self-reported their anxiety levels. Participants first completed a short-term memory test. During and after a forehead cold pressor task (stress vs. control procedure) participants completed a working memory test. Salivary cortisol was taken at baseline and after the last working memory test. Results: Overall, acute stress had no effect on working memory. However, we found that anxiety levels mediated the influence of condition (stressed vs. control) on working memory, but only among those individuals who had high cortisol levels after exposure to acute stress, supporting a moderated mediation model. Conclusions: These results imply that activation of the hypothalamic–pituitary–adrenal axis was necessary for working memory impairment in anxious individuals. These results provide support for the ACT.     

Are Citizens “Receiving the Treatment”? Assessing a Key Link in Contextual Theories of Public Opinion and Political Behavior

The theorization and empirical exploration of contextual effects is a long‐standing feature of public opinion and political behavior research. At present, however, there is little to no evidence that citizens actually perceive the local contextual factors theorized to influence their attitudes and behaviors. In this article, we focus on two of the most prevalent contextual factors appearing in theories—racial/ethnic and economic context—to investigate whether citizens' perceptions of their local ethnic and economic contexts map onto variation in the actual ethnic composition and economic health of these environments. Using national survey data combined with Census data, and focusing on the popular topics of immigration and unemployment, we find that objective measures of the size of the immigrant population and unemployment rate in respondents' county and zip code strongly predict perceived levels of local immigration and assessments of the health of one's local job market. In addition to demonstrating that citizens are “receiving the treatment,” we show that perceptions of one's context overwhelmingly mediate the effect of these objective contextual factors on relevant economic and immigration attitudes. The results from our analyses provide scholars with unprecedented evidence that a key perceptual process presumed in various contextual theories of political attitudes and behavior is, in fact, valid.     

In Search Of True Things Worth Knowing: Considerations For A New Article Prototype

Within social and personality psychology, the existing “old prototype” of a publishable article is at odds with new expectations for transparent reporting. If researchers anticipate having to report everything while continuing to aim for a research product that includes multiple studies, examining a novel effect, with only statistically significant results, this will have negative implications for initial decisions about what research to conduct. First, researchers will be discouraged from collecting additional data because this could potentially mar existing findings. Second, they will be discouraged from pursuing questions for which the answers are unknown, as this would be a waste if the results do not fit old‐prototype expectations. These practices undermine what seem to be two universal values within personality and social psychology: truth and interestingness. Suggestions for a “new prototype” that de‐emphasizes p‐value cutoffs, multiple studies, and novelty will be discussed with an eye toward encouraging research decisions that foster true and interesting findings.     

Can dogs use vocal intonation as a social referencing cue in an object choice task?

Evidence from the literature indicates that dogs’ choices can be influenced by human-delivered social cues, such as pointing, and pointing combined with facial expression, intonation (i.e., rising and falling voice pitch), and/or words. The present study used an object choice task to investigate whether intonation conveys unique information in the absence of other salient cues. We removed facial expression cues and speech information by delivering cues with the experimenter’s back to the dog and by using nonword vocalizations. During each trial, the dog was presented with pairs of the following three vocal cues: Positive (happy-sounding), Negative (sad-sounding), and Breath (neutral control). In Experiment 1, where dogs received only these vocal cue pairings, dogs preferred the Positive intonation, and there was no difference in choice behavior between Negative or Breath. In Experiment 2, we included a point cue with one of the two vocal cues in each pairing. Here, dogs preferred containers receiving pointing cues as well as Negative intonation, and preference was greatest when both of these cues were presented together. Taken together, these findings indicate that dogs can indeed extract information from vocal intonation alone, and may use intonation as a social referencing cue. However, the effect of intonation on behavior appears to be strongly influenced by the presence of pointing, which is known to be a highly salient visual cue for dogs. It is possible that in the presence of a point cue, intonation may shift from informative to instructive.     

One Hundred Years of Reading Research: Successes and Missteps of Edmund Burke Huey and Other Pioneers

For more than 100 years, research on the psychology of reading has proliferated. In this article, the authors wish to help modern reading researchers understand the origins of the discipline and benefit from its history. This article draws heavily on Edmund Burke Huey's 1908 landmark volume The Psychology and Pedagogy of Reading, the first scientific treatise in the field of literacy. Starting with Huey, some of the early pioneers’ enduring contributions to the field are highlighted but especially their scientific mistakes that ultimately led the field in promising new directions. An overview of the modern controversy between phonics and whole language instruction is underscored regarding how it arose from early errors.     

Single-trial learning of "what" and "who" information in a gorilla (Gorilla gorilla gorilla): implications for episodic memory

Single-trial learning and long-term memory of "what" and "who" information were examined in an adult gorilla (Gorilla gorilla gorilla). We presented the gorilla with a to-be-remembered food item at the time of study. In Experiment 1, following a retention interval of either approximately 7 min or 24 h, the gorilla responded with one of five cards, each corresponding to a particular food. The gorilla was accurate on 70% of the short retention-interval trials and on 82% of the long retention-interval trials. In Experiment 2, the food stimulus was provided by one of two experimenters, each of whom was represented by a card. The gorilla identified the food (55% of the time) and the experimenter (82% of the time) on the short retention-interval trials. On the long retention-interval trials, the gorilla was accurate for the food (73%) and for the person (87%). The results are interpreted in light of theories of episodic memory.

A replication of preference displacement research in children with autism spectrum disorder

The purpose of this paper was to replicate previous research on preference displacement with edible and leisure stimuli. In the present study, the experimenters evaluated preference displacement in 25 children with autism spectrum disorder using combined multiple stimulus without replacement preference assessments that consisted of highly preferred edible and leisure stimuli. In addition, the experimenters used a block randomization procedure to evaluate if assessment order influenced displacement outcomes. The experimenters observed patterns of complete displacement by edible stimuli for four participants and complete displacement by leisure stimuli for two participants; assessment order did not influence outcomes. The results and implications are discussed.
