Social factors influence haloperidol-induced catalepsy in rat

This study employed manipulations which presumably influence social interactions in rats: (1) paired housing with a heavier conspecific and (2) exposure to the odors of other rats. The dependent variable was the akinetic state induced by haloperidol, a neuroleptic and dopamine antagonist. In Experiment 1, adult male Long-Evans hooded rats were matched by weight and caged alone or in pairs with one rat 30 g heavier than its cagemate. All rats received haloperidol (1.5 mg/kg) and catalepsy testing. Heavy rats showed more catalepsy than the lighter member of pairs or weight-matched, singly housed controls. In Experiment 2, adult male rats were left unrecaged or were recaged into cages with bedding recently soiled by females or other adult males. After haloperidol (1.0 mg/kg), the rats exposed to bedding soiled by other adult males showed more catalepsy than did the control groups. Thus, the results of both experiments indicated that social factors can influence the akinesia induced by dopamine antagonists.     

Old and new controversies in the alternative treatment of attention-deficit hyperactivity disorder

Use of complementary and alternative medicine (CAM) for treatment of attention-deficit hyperactivity disorder (ADHD) has become widespread in both referral and primary care populations. We review the purported mechanism of action and available evidence for selected CAM therapies for ADHD. Enduring controversies, such as elimination of artificial food additives, colors, and/or preservatives; the effect of sugar on behavior in children; and the use of EEG biofeedback, have been well studied but lack support as effective sole treatments for ADHD. The initial evidence for some emerging CAM therapies, such as essential fatty acid supplementation, yoga, massage, homeopathy, and green outdoor spaces, suggests potential benefits as part of an overall ADHD treatment plan. More rigorously designed studies are needed to evaluate their effectiveness as single therapy for ADHD.     

Alcohol and Drug Use, and Depression Among Hispanic Men in Early Adulthood

Community research and clinical practice have shown that alcohol and drug use and depression are interrelated. Among Hispanics, acculturation may play a role in these relationships. To investigate these relationships as well as alcohol-related problems, we interviewed 288 Puerto Rican, Dominican, and Colombian men in early adulthood. No significant differences emerged in the proportions of abstainers across the three groups. Colombians drank significantly more frequently and had more alcohol-related problems than Dominicans. Dominicans were at least risk for and least likely to have alcohol-related problems. Puerto Ricans were much more likely to use drugs than the other Hispanic men. Drug use was associated with an increased likelihood of heavy drinking which, in turn, increased the risk of drug use and depression. Acculturation decreased the risk of drug use. Results are discussed in terms of implications for community psychology research and interventions.     

Ideology,modernization and politico-economic development in Latin America

The authors state that social and political processes are continuously interrelated and modify each other in a circular fashion. The economic variable seems to be the most independent and strategic one in the complex and circular causal process of contemporary history. Its importance is due to the fact that economic forces have become the means that contribute the most to the attainment of varied social and political goals. holding appointments in the Department of International Relations, Economics, Political Science and Sociology/Anthropology.

Effects of left-hand preference on postinjury measures of distal motor ability

The relationship of preinjury left-hand dominance for motor performance to postinjury distal motor skills following penetrating brain wounds in patients without overt hemiplegia was examined. We studied 13 controls, 13 right-hemisphere brain-damaged patients, and 11 left-hemisphere brain-damaged patients on motor tasks measuring reaction time, strength, and coordination. Our results indicated that no persistent deficits were seen on distal motor tasks in left-handed adults who suffered a penetrating brain wound. These findings are compatible with the relative sparing of persistent neuropsychological deficits in left-handers following brain damage.     

The role of vision in auditory distance perception

In humans, multisensory interaction is an important strategy for improving the detection of stimuli of different nature and reducing the variability of response. It is known that the presence of visual information affects the auditory perception in the horizontal plane (azimuth), but there are few researches that study the influence of vision in the auditory distance perception. In general, the data obtained from these studies are contradictory and do not completely define the way in which visual cues affect the apparent distance of a sound source. Here psychophysical experiments on auditory distance perception in humans are performed, including and excluding visual cues. The results show that the apparent distance from the source is affected by the presence of visual information and that subjects can store in their memory a representation of the environment that later improves the perception of distance.     

The Life Satisfaction of Owner-Manager Entrepreneurs When the Business of Business is not only Business

This paper studies the anatomy of entrepreneurs’ satisfaction with life, which refers to the relationship between life satisfaction, satisfaction in domains of life, and affective, evaluative, and sensory experiences of being well. The paper focuses on owner-manager entrepreneurs, who, as managers, lead their firms and take major business decisions and, as owners, have room to deviate from the exclusive procurement of profits to pursue their happiness. The study of entrepreneurs’ anatomy of life satisfaction provides insight on how they lead their firms and how they weight the well-being repercussions of their business decisions. The paper distinguishes between family-firm and nonfamily-firm entrepreneurs, and it shows that there is heterogeneity in entrepreneurs’ anatomy of life satisfaction; with the life satisfaction of family-firm entrepreneurs being strongly driven by family satisfaction and by negative affect, while the life satisfaction of nonfamily-firm entrepreneurs is strongly driven by work satisfaction. These differences in the anatomy of entrepreneurs’ life satisfaction do correspond with observed differences in the organization and behavior of family and nonfamily firms, which suggests that the anatomy of life satisfaction provides insight on how entrepreneurs weight their business decisions and lead their firms. The empirical exercise is based on an original survey applied to Spanish entrepreneurs in 2019.

     

To switch or not to switch: Inviting bilingual clients to switch languages in psychotherapy

In the present study, we used an audio-analog design to test whether exposing bilingual participants to a therapist who invited a bilingual client to switch languages in a psychotherapy session would have a positive effect on participants’ perceptions of the therapist. We also explored whether participants’ sense of belonging to their ethnic group and to the larger US culture would enhance or attenuate this effect. Sixty-three bilingual Latino/a university students listened to one of two recordings of a simulated psychotherapy session with a bilingual Latina therapist and client. In one recording, the therapist invited the client to switch from English to Spanish when the client had trouble expressing complicated feelings; in the other, the therapist did not invite the client to switch. When listening, participants were asked to imagine themselves in the role of client and to rate the credibility and multicultural competence of the therapist, and the emotional bond they would anticipate with her. Contrary to expectation, only participants who expressed a greater sense of belonging to US culture rated the therapist who invited the client to switch as being more multiculturally competent. We discuss how these findings contribute to the literature on language switching and bilingualism in psychotherapy.     

US Retirement Migration to Mexico: Understanding Issues of Adaptation,Networking, and Social Integration

This paper describes the cultural adaptation of American retirees living in two traditional retirement destinations in Mexico (Lake Chapala, state of Jalisco and San Miguel de Allende, state of Guanajuato). Based on 375 surveys and follow-up interviews, the authors discuss issues of adaptation, identity, and networking with the American and local community. Findings present a complex picture of adaptation and integration to the Mexican community as well as networking with other US residents. The comparative case study allows researcher to see the different social and economic dynamics taking place in the two destinations. This study contributes to understand a largely ignored migration flow that is directly related to the aging of the baby boomers generation.     

Neuronal effects of auditory distraction on visual attention

Selective attention in the presence of distraction is a key aspect of healthy cognition. The underlying neurobiological processes, have not, however, been functionally well characterized. In the present study, we used functional magnetic resonance imaging to determine how ecologically relevant distracting noise affects cortical activity in 27 healthy adults during two versions of the visual Sustained Attention To Response Task (SART) that differ in difficulty (and thus attentional load). A significant condition (noise or silence) by task (easy or difficult) interaction was observed in several areas, including dorsolateral prefrontal cortex (DLPFC), fusiform gyrus (FG), posterior cingulate (PCC), and pre-supplementary motor area (PreSMA). Post hoc analyses of interaction effects revealed deactivation of DLPFC, PCC, and PreSMA during distracting noise under conditions of low attentional load, and activation of FG and PCC during distracting noise under conditions of high attentional load. These results suggest that distracting noise may help alert subjects to task goals and reduce demands on cortical resources during tasks of low difficulty and attentional load. Under conditions of higher load, however, additional cognitive resources may be required in the presence of noise.
