Effects of stress management and relaxation training on the relationship between diabetes symptoms and affect among Latinos

Objective: Stress management and relaxation (SMR) interventions can reduce symptoms of chronic disease and associated distress. However, there is little evidence that such interventions disrupt associations between symptoms and affect. This study examined whether SMR dampened the link between symptoms of hyperglycemia and proximal levels of affect. We predicted that during periods of increased hyperglycemia, individuals receiving SMR training, relative to controls, would demonstrate smaller increases in negative affect.

Design: Fifty-five adult Latinos with type 2 diabetes were randomised to either one group session of diabetes education (DE-only; N = 23) or diabetes education plus eight group sessions of SMR (DE + SMR; N = 32). After treatment, participants reported five diabetes symptoms and four affective states twice daily for seven days using a bilingual telephonic system.

Results: Mean age = 57.8 years, mean A1c = 8.4%, and ¾ was female with less than a high school education. Individuals receiving DE + SMR, compared to DE-only, showed a weaker positive within-person association between daily diabetes symptoms and nervous affect. Groups also differed on the association between symptoms and enthusiasm. Age moderated these associations in most models with older individuals showing less affect reactivity to symptoms.

Conclusions: Findings provide partial support for theorised mechanisms of SMR.     

Reentry as Experienced by Women in Jail: Advocating for Change

We conducted a phenomenological study with 35 women in a substance abuse treatment jail program about their lived experiences in preparing for reentry. The women addressed their past, the needs of their families, and education of criminal justice personnel, providers, and the whole citizenry. The women advocated for effective reentry practices.     

Effects of neonatal treatment with cyproterone acetate on aggressive behavior induced by footshock in adult male rats

High levels of androgens are required to organize aggressive behavior in adult male rats. Footshock-induced aggression was tested in Wistar rats allocated to one of three experimental groups: control (oil-injected) males (M), males neonatally injected with the antiandrogen cyproterone acetate (CA), and males treated as in the CA group but gonadectomized just before puberty (CAG). An antiaggressive effect of CA in those adult male rats neonatally treated with this compound was found. Neonatal exposure to cyproterone acetate exerts an antiandrogenic effect over the expression of shock-induced aggressive behavior. The behavioral effects of CA were not countered by adult treatment with testosterone propionate.     

An analysis of sustainable consumption practices through the role of the consumer behavior in the circular economy

Sustainable consumption analyses the choice of products to address environmental issues. In recent years, the circular economy model () has offered strategies as possible solutions to address the growing demand for action on climate justice. The success of a business model depends on understanding the consumer's role. The power of individual consumer actions is vital for minimizing the adverse impacts of climate change. Although the effectiveness of in the business sector has been studied, the literature has ignored the role of consumers in sustainable consumption practices through. Thus, using a survey technique, this quantitative study analyzed part of the theoretical model of Mostaghel and Chirumalla to analyze how awareness and consumer attitude significantly impact purchase intention and ethical purchasing behavior. The data analyzed through PLS-SEM reflected several theoretical implications in the forms of consumer behavior, a topic that has not been addressed in the literature.     

The role of stress on the language-independence and code-switching phenomena

this investigation studies the extent to which stress affects the assumed functional separation of coordinate bilingual's linguistic organization. Spanish/English bilinguals were subjects in a GSR linguistic conditioning experiment using two intensities of buzzer sounds (stressful conditions) and two lists of words. One word for each list functioned as the conditioned stimulus. Generalization to semantically, phonemically, and unrelated words occurred in both languages and buzzer conditions. We found a differential impact of the buzzer on the functional separation of the languages, although not in the direction predicted. We concluded that stress produced code-switching, and hence, a primitivization of the subject's cognitive and linguistic functioning is assumed to have occurred. These findings are important in understanding the way stress affects the bilingual's languages at the linguistic and cognitive levels. They are also important in understanding the role of stress in language development and in the transfer of linguistic information.Different portions of this paper were presented at several scientific meetings, including the conference on Treating Hispanic Clients: Cultural, Ethnic and Linguistic Considerations, Long Island University, May 1986, and the Annual Convention of the New York State Psychological Association, April 1987     

Controlling nonverbal displays: Facial expressions and tone of voice

This study investigated the hypothesis that facial expressions are more controllable and closer to one's awareness than vocal cues. Specifically, it was suggested that nonverbal displays are a function of three factors: (a) expressiveness, or the tendency to display spontaneous nonverbal cues: (b) controllability, or the ability to voluntarily suppress or exaggerate one's spontaneous display: and (c) demeanor, or the sender's tendency to convey a particular impression regardless of his/her experienced emotion. Subjects' facial and vocal reactions to affective stimuli were recorded in a spontaneous condition or under instructions to magnify or conceal reactions to these stimuli. It was shown that information conveyed by facial expressions was best accounted for by controllability whereas information conveyed by tone of voice was best accounted for by expressiveness and demeanor.     

Learning-disordered children's evoked potentials during sustained attention

Evoked potentials and performance of 19 learning-disordered (LD) and 19 normally achieving children were studied in two versions of the Continuous Performance Test (CPT). In both CPT procedures, LD children made more errors of omission and commission than did normal children. Evoked potential differences between groups were especially prominent in the more difficult BX version of the CPT. LD children displayed significantly smaller late positive components (LPC) of the evoked potential to critical stimuli in the task. There were no LPC differences between diagnostic groups for noncritical stimulus categories. The results suggest a deficit in behavioral and cortical indices of sustained attention among LD children.This research is based on a doctoral dissertation in psychology submitted by the first author (Dainer, 1980) and supervised by the second author.

Memory-Enhancing Treatments Do Not Reverse the Impairment of Inhibitory Avoidance Retention Induced by NMDA Receptor Blockade

The aim of the present research was to verify whether the impairment of retention induced by the N-methyl-d-aspartate (NMDA) receptor blocker (+)-10,11-dihydro-5-methyl-5H-dibenzo[a,d]cycloheptene-5,10 imine (MK-801) can be reversed by memory-enhancing treatments. Adult female Wistar rats were trained and tested in a step-down inhibitory avoidance task (0.3-mA foot shock, 24-h training-test interval). Animals were given an ip injection of saline (SAL) or MK-801 (0.0625 mg/kg) 30 minutes before training, and an ip injection of SAL, epinephrine (EPI) (25 microg/kg), the opioid receptor antagonist naloxone (NAL) (0.4 mg/kg), the glucocorticoid receptor agonist dexamethasone (DEX) (0.3 mg/kg), or glucose (GLU) (320 mg/kg) immediately after training. There was an impairment of inhibitory avoidance retention in the MK-801-SAL, MK-801-EPI, MK-801-NAL, MK-801-DEX, and MK-801-GLU groups. There was an enhancement of retention in the SAL-EPI, SAL-NAL, SAL-DEX, and SAL-GLU groups. A control experiment showed that the amnestic effects of MK-801 could not be attributed to decreased reactivity to the foot shock. The results suggest that memory-enhancing treatments directed at modulatory mechanisms do not reverse the memory impairment induced by NMDA receptor blockade.     

Methylphenidate speeds evaluation processes of Attention Deficit Disorder adolescents during a continuous performance test

Fortysix Attention Deficit Disorder (ADD) adolescents took a Continuous Performance Test (CPT) under placebo and methylphenidate (35.33 mg/day). The task required pressing one button for targets (p=133),and another button for nontargets. Subjects displayed a strong bias to make the more frequent negative response before completely evaluating stimuli. Consistent with this assumption, subjects responded faster (by an average of 87 ms) to nontargets than to targets. Methylphenidate increased accuracy and speeded reaction times (RTs) to targets. The drug also increased the amplitude of the P3b component of the eventrelated potential for nontargets and shortened the latency of P3b for both targets and nontargets. These results suggest increased capacity allocation to and faster evaluation of task stimuli. Finally, the stimulant lengthened relative motor processing time (RT-P3b latency) for nontargets, a finding implying that response processing was accomplished with the benefit of earlier completion of evaluation processes for these stimuli.Portions of these findings were reported at the meeting of the Society for Research in Child and Adolescent Psychopathology, Costa Mesa, California, January 24–26, 1990.
