Stress and subjective life expectancy: Cross-sectional and longitudinal associations in early adolescence

Using data from a longitudinal study, the present study employed a latent class mover-stayer analytical strategy to examine both the cross-sectional and longitudinal (+33 months) relationship between membership of stress classes, and subjective life expectancy. Participants were from 21 High schools in Scotland and Northern Ireland. Data were collected in the first year of High school (mean age = 12.5 years), and at +33 months (fourth year, or school year 11). Sample 1 consisted of 1171 adolescents (40.82% females, 2.56% unreported) in Northern Ireland. Sample 2 consisted of 1059 adolescents (52.79% females, 1.32% unreported) in Scotland. Adolescents with the lowest levels of stress projected the highest subjective life expectancy scores. Longitudinal analyses were jumbled and not in keeping with cross-sectional results. More research may be needed on the trajectory of subjective life expectancy over time before it can be depended upon as a reliable outcome variable in adolescent development.     

The Strategic Practice of “Fiesta” in a Latino Protestant Church: Religious Racialization and the Performance of Ethnic Identity

Founded and led by a U.S.-born white pastor, Amor Poderoso is a nondenominational, evangelical megachurch in El Paso, Texas, almost entirely composed of Mexican-Americans, recent Mexican immigrants, and current Mexican citizens. Ethnographic fieldwork from 2014 to 2017, supplemented with interviews with pastors, worship leaders, and attendees, reveal that much of congregational life orients around intentionally showcasing “Mexican” culture through sounds, images, and artifacts that appropriate an array of idealized ethnic references (e.g., food, dress, mannerisms, clichés) from Northern Mexico. Ongoing ethnic displays do not originate spontaneously or impromptu from membership but rather serve as a form of tactical authenticity derived from U.S. racial schemas mobilized by congregational leaders as a distinctive religious resource. Weekly worship services featuring dialect-inflected Spanish preaching and singing project ethnic signals that elicit connections to both a common ancestral heritage and a common religious identity. In short, church leaders at this southern border Latino church deliberately deploy sounds, images, and artifacts to assert racialized performances of being “Mexican” for distinctly religious purposes, especially evangelization. In the process, the distinctive practices of religious racialization effectively structure church members’ ethnic and religious identities around racial tropes to buttress a cogent corporate identity for enacting institutionalized evangelical narratives and legitimating charismatic authority.     

Validity of the multiple-stimulus without replacement preference assessment for edible items

Studies have shown that the multiple-stimulus without replacement (MSWO) preference assessment is an effective assessment format for identifying preferred items. However, it is possible that factors other than reinforcer quality might influence selections by some individuals when the MSWO array consists of edible items. The validity of the MSWO results was evaluated by comparing items identified as most and least preferred by the MSWO assessment in a concurrent-schedule (CS) format. Varying edible items were used in each study. The MSWO format accurately identified the higher quality edible item for most participants across studies (76%); however, the MSWO format did not predict the highest quality edible item in the CS assessment for 20% to 30% of participants in each study.     

Teaching children with autism spectrum disorder to ask “where” questions using a speech-generating device

Children with autism spectrum disorder (ASD) who have limited speech are often taught to communicate using a speech-generating device (SGD). We evaluated procedures for teaching a mand for information (i.e., Where is [item]?) using an interrupted behavior chain procedure. In Experiment 1, all participants (3 children with ASD who communicated using an SGD) acquired the target mand but transfer to a novel stimulus did not occur. In the second experiment, 2 participants were taught to approach alternative communication partners when the first partner did not provide the information. The second experiment also included procedures to test whether the responses were under the control of appropriate motivating operations (MOs). Generalization across communication partners occurred with both participants, but transfer across behavior chains with only 1 participant. The results of both experiments suggest that teaching multiple behavior chains and evaluating MO control may be necessary to establish generalized manding for information.     

Reducing risky behavior with habit reversal: A review of behavioral strategies to reduce habitual hand-to-head behavior

Habit reversal training (HRT) has been a mainstay of behavior analysts' repertoire for nearly the last 50 years. HRT has been effective in treating a host of repetitive behavior problems. In the face of the current coronavirus pandemic, HRT has practical public health importance as a possible intervention for reducing hand-to-head behaviors that increase the risk of viral infection. The current paper provides a brief review of HRT for hand-to-head habits that is designed for a broad audience and concludes with practical suggestions, based on HRT, for reducing face-touching behaviors.

Stress for families today

Rapid changes in family life have created enormous challenges and pressures on developing families - divorce, two working parents, disappearance of the extended family, unclear cultural values for our children's future, poorly defined support systems for stressed families, inadequate substitute care when both parents work-all contribute to an anxious atmosphere for young families. Parents who must return to work „too early”︁ (and we have no established standards yet for what this means to either child or adult development) seem to grieve about the loss of the relationship with the developing child. They may even set up defenses against making a strong and painful attachment. They may not become involved in the child's development in a way that will foster their own development as nurturing adults. The grieving and the necessary defenses against it are predictable and must be mitigated in order to foster nurturing adults within the family. Children must be provided with caring, intensely involved adults in order to assure their optimal future development. We must provide them and their parents with adequate substitute care. This paper suggests adjustments at the industrial level that must be made to foster parental involvement and to assure positive outcomes for future generations.     

Identification of a reinforcement pathway necessary for operant conditioning of head waving in Aplysia californica

The marine mollusc Aplysia californica exhibits a wide range of nonassociative and associative forms of learning. Recently, we found that the learning repertoire of Aplysia includes operant conditioning (Cook & Carew, 1986, 1989b). The behavior we examined is a naturally occurring, side-to-side head-waving response used by Aplysia in seeking food, obtaining a foothold, and egg laying. Aplysia can be operantly conditioned to reduce head-waving to one side of their body if such a response results in exposure to bright uniform-field illumination, which the animals find aversive. An essential step toward achieving a mechanistic understanding of operant conditioning is to identify and characterize the reinforcement pathway used during the learning. Toward this end, we wished to determine which of the peripheral visual pathways in Aplysia are critical for performance of the operant task. Previous experiments indicated that photic input from the optic and rhinophore nerves functionally inhibited motor neurons that participate in the operant response (head-waving), while photic input from the oral veil nerves excited these same motor neurons (Cook & Carew, 1989c). These findings suggested the hypothesis that one or both of these pathways could play an important role in mediating reinforcement during training. To explore this possibility we operantly trained animals that had received chronic bilateral transections of either the optic and rhinophore nerves or the oral veil nerves C1-C3 (in conjunction with transection of the optic and rhinophore nerves). We found that operant conditioning was not disrupted by ablation of input from the eyes and rhinophores. By contrast, ablation of input from the oral veil (together with that from the eyes and rhinophores) abolished operant conditioning. Thus, the oral veil nerves play a critical modulatory role in operant conditioning of head-waving. This observation further suggested that photic input from the oral veil is conveyed to the CNS via the oral veil nerves. In a final experiment we confirmed that stimulation of the oral veil with light evokes increased afferent activity in the oral veil nerves C1-C2. These results support the idea that the oral veil nerves contain processes that are critical components of the reinforcement pathway for operant conditioning of head-waving.     

REM sleep deprivation increases early morning pineal melatonin in castrated rats

Recently nighttime melatonin levels have been shown to be attenuated in depressive patients or patients with dementia of the Alzheimer type. On the other hand, depression can be transiently relieved by deprivation of rapid eye movement sleep. Since exogenous melatonin administration increases rapid eye movement sleep and slow wave sleep in the rat, could rapid eye movement sleep deprivation then inversely influence endogenous melatonin production? We found indices that in castrated Wistar rats 4 days of rapid eye movement sleep deprivation by the cuff pedestal method elevates the pineal content of melatonin by a factor of two at 1 to 2 h after light onset. Rapid eye movement sleep is thus suggested to influence pineal activity. This mechanism might be involved in the human depression-alleviating effect of rapid eye movement sleep deprivation.
