Schedule control of the vocal behavior of Cebus monkeys

The vocal behavior of three Cebus monkeys was maintained by fixed-ratio schedules of response dependent reinforcement at values between fixed-ratio 1 and fixed-ratio 15. In one monkey that was exposed to variable-interval, fixed-interval, and conjunctive fixed-ratio fixed-interval schedules of reinforcement, vocal responding occurred at a low rate, but schedule-appropriate patterns were maintained. The rates and patterns of responding engendered indicated that the vocal operant can be brought under schedule control in the monkey by the use of response-dependent reinforcement.     

PARENT REINFORCEMENT FOR CHILD ACHIEVEMENT: THE USE OF A LOTTERY TO MAXIMIZE PARENT TRAINING EFFECTS

This study describes and evaluates a reinforcement program in which parents earned lottery tickets and won prizes for the progress made by their handicapped children during home-based intervention. An ABAB reversal design replicated across three families was used to assess the effects of the lottery on the children's mastery of language skills. Results showed that the reinforcement of the parents for training accomplishments, as indexed by their children's achievements, produced clinically significant increases in the children's progress when compared with the children's progress under the routine supportive practices of the baseline condition. The implications of the findings for parent training programs in general are discussed.     

From egocentric to exocentric spatial orientation: development of posture control in bimanual and trunk inclination tasks

The authors investigated the emergence of independent control of body segments in bimanual tasks involving either voluntary or involuntary trunk motion by tracking the transition from an ego- to an exocentric mode of postural control during childhood (i.e., from body-referenced orientation to externally referenced action). A paradigm combining a seated manual task and various trunk manipulations described the coordination strategies used by 24 children at different ages (2 to 9 years) and by adults. The following questions were asked: (a) When do children begin to dissociate upper limb movements from those of the trunk? (b) What segmental strategies are exhibited by each age group (2-3, 4-6, and 7-9 years, and adults)? Kinematic analyses revealed that younger children (2-6 years) used either the trunk or the support surface as reference to orient the limbs. Older children (7-9 years) began to use a gravitational reference frame similar to that of adults; they uncoupled upper limb motion from the trunk in either voluntary or imposed conditions. Young children patterned the forearm trajectory after the initiating segment (support surface or the trunk), thus reducing the degrees of freedom during the dual task. Echoing previous reports, 7-9 years of age appears to be a critical period in which children master postural control and develop an internal representation of body scheme.     

The Rational Choice Approach to Human Studies: A Reexamination

This article reexamines the rational choice or economic approach to human studies. Its adherents claim that its extension beyond its original domain to all human behavior can finally lead to integration of the human studies, especially social theory, and thus their elevation from what they see as a chaotic state. Specifically, they propose grounding human studies on the premise that humans are rational egoists or self-interested utility maximizers. Although this premise has been the conceptual foundation of orthodox economic theory, it has been questioned, and even in part discredited in its heterodox versions. This reexamination casts serious doubts on such claims.     

Revisiting the suitability of antisaccade performance as an endophenotype in schizophrenia

Poor performance on the antisaccade task has been proposed as a candidate endophenotype in schizophrenia. Caveats to this proposal, however, include inconsistent findings in first-degree relatives of individuals with schizophrenia, and substantial heterogeneity in individuals with the disorder. In this study, we examined antisaccade performance in patients and relatives, and sought to establish whether antisaccade measures could differentiate between two patients clusters identified in the Western Australian Family Study of Schizophrenia with either pervasive cognitive deficits (CD) or cognitively spared (CS). Ninety-three patients (CD = 47, CS = 46), 99 relatives and 62 healthy controls carried out a standard antisaccade task. Results showed: (i) significantly greater error rate, and prolonged latencies to correct responses and self-correction saccades in patients compared with controls; (ii) high error rates in relatives of poorly performing patients; (iii) longer latencies of self-correction saccades in relatives compared to controls; and (iv) higher error rate and longer latencies of self-correction saccades in the CD subgroup compared with CS. Unaffected relatives as a group were unimpaired in error rate as compared to healthy controls. These findings suggest that the antisaccade error rate and latency of self-correction saccades are useful measures in specific applications of genetic research in schizophrenia, without fully meeting endophenotype co-familiality requirements.     

Spiritual Versus Religious Identity: A Necessary Distinction in Understanding Clinicians’ Behavior and Attitudes Toward Clinical Practice and Medical Student Teaching in This Realm

Social sciences view spirituality and religion separately; medicine views them together. We identified distinctions regarding clinical practice and teaching among clinician educators based on their self-identified spirituality versus religiosity. We emailed a 24-item survey on spiritual/religious (S/R) issues to clinician educators (n = 1,067) at our institution. Three summary scales were created. Responses to statements, ‘I consider myself to be spiritual’ and ‘I consider myself to be religious’ generated four comparison groups: ‘spiritual only,’ ‘religious only,’ ‘both spiritual and religious’ and ‘neither.’ Analyses employed ANOVA and T tests. A total of 633 (59 %) surveys were completed. Four percentage self-identified as ‘religious only’; remaining respondents divided evenly, about 30 % into each of the other categories. Groups differed from one another on all summary scales (p < .0001). Using T tests, the ‘spiritual only’ group differed from the ‘religious only’ group regarding teaching. The ‘spiritual and religious’ group had the highest mean ratings for all summary scales. The ‘neither’ and ‘religious only’ group had the lowest mean ratings. Clinicians’ spiritual versus religious identity is associated with differences in behavior/attitudes regarding S/R toward clinical practice and medical student teaching. These findings elucidate opportunities for faculty development to explore effects of beliefs on behavior and attitudes within this realm.     

Calvinist Predestination and the Spirit of Capitalism: The Religious Argument of the Weber Thesis Reexamined

The paper reconsiders the Weber Thesis of a linkage between Calvinism and capitalism. It first restates this sociological Thesis in terms of the Calvinist doctrine of predestination as its theological core and premise in virtue of being treated as the crucial religious factor of the spirit of modern capitalism. Consequently, it proposes that the Weber Thesis’ validity and consistency depends on that doctrine, succeeding or failing as a sociological theory with the latter depending on whether or not it is unique in theological terms, as well as economic-social consequences. For that purpose, it reexamines and compares the Calvinist doctrine of predestination with the pre-Calvinist versions and infers that it is basically identical to or compatible with these. It then draws the implications for the Weber Thesis in respect of the degree of its validity or consistence. It concludes that the Weber Thesis likely is fail as a sociological-economic theory with the Calvinist doctrine of predestination to the extent that the latter is its theological ground and revealed not to be unique and new theologically and probably in terms of its societal effects.     

The Mistreatment of My People: Victimization by Proxy and Behavioral Intentions to Commit Violence Among Muslims in Denmark

Islamist extremism is often explained by the suffering endured by Muslims in Islamic countries as a result of Western‐led wars. However, many terrorist attacks have been carried out by European Muslims with no personal experiences of war. Across two studies among Danish Muslims, we tested if what we call “victimization‐by‐proxy processes” motivate behavioral intentions to commit acts of violence. We used Muslim identification, perceived injustice of Western foreign policies, and group‐based anger to predict violent and nonviolent behavioral intentions. More importantly, we compared path models of Danish Muslims from conflict zones with those without direct personal experience of Western‐led occupation. We found similar effects among the participants in each category, that is, vicarious psychological responses mimicked those of personally experienced adversity. In fact, participants born in Western Europe were, on average, more strongly identified with Muslims, more likely to perceive Western foreign policy as more unjust, reported greater group‐based anger, and were more inclined to help Muslims both by nonviolent and violent means.     

Living under threat: Mutual threat perception drives anti‐Muslim and anti‐Western hostility in the age of terrorism

This research demonstrates a common psychology of outgroup hostility driven by perceived intergroup threat among three groups and seven cultural contexts: non‐Muslim Westerners, Muslims in Western societies, and Muslims in the Middle East. In Study 1, symbolic, but not realistic and terroristic threats, predicted non‐Muslim Norwegians' intentions to join anti‐Islamic movements. In Study 2, symbolic and realistic, but not terroristic threat, predicted non‐Muslim Americans' willingness to persecute Muslims. In Studies 3 and 4, symbolic threat predicted support and behavioral intentions against the West among Swedish and Turkish Muslims. Finally, in Study 5, a comparison demonstrated that symbolic and realistic threats had the same effects on violent intentions among non‐Muslim and Muslim Danes, and Muslims in Afghanistan. Meta‐analysis showed that symbolic threat was most strongly associated with intergroup hostility. Across studies, participants with high religious group identification experienced higher levels of threat. Implications for intergroup research and prejudice reduction are discussed.     

Marketing of Professional Counselors: A Q‐Sort Study of Best Practices

This quantitative Q‐sort research was designed to evaluate representations of counselor qualifications and to determine which configurations account for the variance in consumer preference and selection. The sample consisted of 161 graduate and undergraduate students in a regional university in Texas. An iterative inverse factor analysis produced 3 distinct factors that accounted for 65.85% of the variance in the data, explaining a majority of the differences in how consumers perceive counselor credentials.
