Development of brain functional connectivity and its relation to infant sustained attention in the first year of life

The study of brain functional connectivity is crucial to understanding the neural mechanisms underlying the improved behavioral performance and amplified ERP responses observed during infant sustained attention. Previous investigations on the development of functional brain connectivity during infancy are primarily confined to the use of functional and structural MRI techniques. The current study examined the relation between infant sustained attention and brain functional connectivity and their development during infancy with high‐density EEG recordings. Fifty‐nine infants were tested at 6 (N = 15), 8 (N =14), 10 (N = 17), and 12 (N = 13) months. Infant sustained attention was defined by measuring infant heart rate changes during infants’ looking. Functional connectivity was estimated from the electrodes on the scalp and with reconstructed cortical source activities in brain regions. It was found that infant sustained attention was accompanied by attenuated functional connectivity in the dorsal attention and default mode networks in the alpha band. Graph theory analyses showed that there was an increase in path length and a decrease in clustering coefficient during infant sustained attention. The functional connectivity within the visual, somatosensory, dorsal attention, and ventral attention networks and graph theory measures of path length and clustering coefficient were found to increase with age. These findings suggest that infant sustained attention is accompanied by distinct patterns of brain functional connectivity. The current findings also suggest the rapid development of functional connectivity in brain networks during infancy.     

Comparing structured mix and random rotation procedures to teach receptive labeling to children with autism

We compared two procedures using an alternating treatments design to teach receptive labeling to children with autism. The structured mix procedure followed seven steps entailing mass trials, intermixing, and random rotation. In the random rotation procedure, we trained all stimuli from the start. Study 1 included four children with a repertoire of four to 50 receptive labels and who primarily communicated with an alternative communication device. Results showed that the two conditions were comparable for one participant, structured mix was effective and random rotation was not effective for one participant, and that both conditions were ineffective for two participants. Study 2 included five children with over 200 receptive labels in their repertoire and with vocal speech as the primary form of communication. Four participants acquired the labels in both procedures, but random rotation was more effective. Results indicate that structured mix may be more effective for participants with a limited language repertoire and random rotation is more effective for participants with a larger language repertoire.     

Reducing speech disfluencies during public speaking using brief habit reversal

Recent research has evaluated the effects of brief habit reversal, consisting of either awareness training (AT) and competing response training (Mancuso & Miltenberger, 2016), or AT alone (Spieler & Miltenberger, 2017) in reducing speech disfluencies during public speaking. Although both formats of brief habit reversal reduced rates of speech disfluencies, results suggested that teaching a competing response (CR) may produce better outcomes. We aimed to replicate and extend those studies by evaluating the effects of AT and instructing the use of a CR (a silent pause) on rates of speech disfluencies and CRs during public speaking. Following training, all 4 participants demonstrated a reduction of speech disfluencies, and 1 participant demonstrated moderate levels of CRs when giving a speech in front of both a single experimenter and small audience. For 1 participant, generalized effects were demonstrated when presenting in front of a class.     

Comparing detailed and less detailed pre-lineup instructions

It is generally agreed that proper pre-lineup instructions can reduce the rate of mistaken identifications of innocent suspects. However, the exact nature of these instructions has not been empirically established. We compared the effects of the detailed pre-lineup instructions recommended by the US Department of Justice to a simple instruction that the perpetrator may or may not be present. Both forms of unbiased instructions significantly reduced mistaken identifications when compared with biased instructions. Comparison of performance using the utility-based analysis deviation from perfect performance demonstrated that unbiased instructions are to be preferred under assumptions of low base rates or high costs of mistaken identifications and do as well as biased instructions under assumptions of high base rates or low cost of misidentification.     

Shifting probation culture and advancing juvenile probation reform through a community‐based,participatory action research‐informed training

Many jurisdictions are currently transforming their juvenile probation systems to reflect research‐informed, developmentally based case management approaches. Training, developed through a community‐based, participatory action research (CBPAR) framework and guided by a community–academic partnership, may promote probation staff's readiness for such change. This paper examined whether such training could serve as an effective method to impact organizational culture by exploring shifts in probation staff's knowledge, attitudes, and beliefs about graduated response – a structured juvenile probation case management system that aligns with research on adolescent development and youth behavior change. Data came from 559 juvenile probation staff trained in graduated response theory and practice between 2016 and 2019. Results demonstrated that at the end of a 1‐day, CBPAR‐grounded training program, participating staff reported significantly more buy‐in to graduated response, greater knowledge of this new system, and attitudes more strongly in favor of graduated response and intended behaviors. Study findings revealed important shifts indicative of readiness for change within juvenile probation departments. Additional implementation strategies are needed to extend training gains and overcome organizational‐ and system‐level barriers to change.     

Advocating for Atheist Clients in the Counseling Profession

Atheism is a controversial topic, with individuals who identify as atheist reporting high rates of discrimination. Despite increasing literature discussing religious/spiritual views and beliefs, few scholarly discussions of atheism in the counseling field can be found. Counselors need to be made aware of the issues facing atheist clients and educated on the best interventions to use in collaborative work with clients. Counselors should also be prepared to advocate for atheist clients in multiple domains. This article aims to explore the relevant literature around atheism, identify implications for counselors, and provide a path to advocacy for counselors in their work with atheist clients.     

On interchangeability of Nash equilibria in multi-player strategic games

The article studies properties of interchangeability of pure, mixed, strict, and strict mixed Nash equilibria. The main result is a sound and complete axiomatic system that describes properties of interchangeability in all four settings. It has been previously shown that the same axiomatic system also describes properties of independence in probability theory, nondeducibility in information flow, and non-interference in concurrency theory.     

Construct Validity of the Rotter Incomplete Sentences Blank With Clinic-Referred and Nonreferred Adolescents

Inferred latent entities, whether those of psychoanalysis, factor analysis, or cluster analysis, have declined in value for many clinical psychologists, both as tools of practice and as objects of theoretical interest. Behavior modification, rational-emotive therapy, crisis intervention, psycho-pharmacology, and actuarial prediction all tend to minimize reliance on latent entities in favor of purely dispositional concepts. Behavior genetics is, however, a powerful movement to the contrary. As regards categorical entities (types, taxa, syndromes, diseases), history reveals no impressive examples of their discovery by cluster algorithms; whereas organic medicine and psychopathology have both discovered many taxonic entities without reliance on formal (statistical) cluster methods. I offer eight reasons for this strange condition, with associated suggestions for ameliorating it. Adopting a realist instead of a fictionist approach to taxonomy, I give high priority to theory-based mathematical derivation of quantitative consistency tests for all taxometric results. I urge a large scale cooperative survey of taxometric methods based on Monte Carlo runs, biological pseudoproblems where the true taxon is independently known, and live problems in genetics, organic medicine, and psychopathology. An empirical example of taxometric bootstrapping and consistency testing was presented from my own current research on schizotypy.     

Emotional expression and heart rate in high-risk infants during the face-to-face/still-face

In infants, eye constriction—the Duchenne marker—and mouth opening appear to index the intensity of both positive and negative facial expressions. We combined eye constriction and mouth opening that co-occurred with smiles and cry-faces (respectively, the prototypic expressions of infant joy and distress) to measure emotional expression intensity. Expression intensity and heart rate were measured throughout the face-to-face/still-face (FFSF) in a sample of infants with prenatal cocaine exposure who were at risk for developmental difficulties. Smiles declined and cry-faces increased in the still-face episode, but the distribution of eye constriction and mouth opening in smiles and cry-faces did not differ across episodes of the FFSF. As time elapsed in the still face episode potential indices of intensity increased, cry-faces were more likely to be accompanied by eye constriction and mouth opening. During cry-faces there were also moderately stable individual differences in the quantity of eye constriction and mouth opening. Infant heart rate was higher during cry-faces and lower during smiles, but did not vary with intensity of expression or by episode. In sum, infants express more intense negative affect as the still-face progresses, but do not show clear differences in expressive intensity between episodes of the FFSF.     

The Psychophysiology of Social Action: Facial Electromyographic Responses to Stigmatized Groups Predict Antidiscrimination Action

We introduced facial electromyography as a tool for predicting advantaged group members' engagement in antidiscrimination action on behalf of a disadvantaged outgroup. Heterosexual men's corrugator supercilii (brow “frowning” muscles) activity while viewing videos of male–male and male–female couples interacting was measured. Corrugator (negative affect) response to male–male versus male–female targets, but not self-reported attitudes toward gay men, predicted number of flyers calling for action to reduce antigay violence and discrimination that participants privately took to distribute. Our discreet behavioral measure mirrored real-life collective action possibilities such as voting against laws prohibiting same-sex marriage in the privacy of one's voting booth.
