The effects of blocking mouthing of leisure items on their effectiveness as reinforcers

Leisure items are commonly used as reinforcers in behavior-analytic applications. However, a defining feature of autism is the occurrence of stereotypy, and individuals with autism often engage leisure items in a stereotyped manner. The opportunity for stereotyped interaction may be the only aspect of a contingent stimulus that makes it a reinforcer for appropriate behavior. Therefore, this study investigated the effects of blocking stereotyped reinforcer interaction on reinforcer efficacy for 2 children with autism. Results showed that blocking stereotypic reinforcer interaction did not influence reinforcer efficacy.     

Patient–Provider Communication About Sexual Health: The Relationship with Gender, Age, Gender-Stereotypical Beliefs, and Perceptions of Communication Inappropriateness

This investigation examined patient–provider communication about sexual health related to gender and age. Data were collected from 277 individuals, aged 18–60, via convenience and snowball sampling at a large university in southwestern United States. Results indicate women are more proactive about their sexual health than men and tested for STDs more frequently. Women, more than men, initiate discussions with their healthcare provider about sexual health matters and healthcare providers are more likely to initiate communication about such matters with women than men. Men hold stronger gender-stereotypical beliefs than women, are less likely to initiate conversations about sexual issues with their provider, and believe sexual discussions with their partner are inappropriate. Age relates to sexual activity initiation and perceived STD risk.     

Image Theory, Social Identity, and Social Dominance: Structural Characteristics and Individual Motives Underlying International Images

The present study provides an empirical test of international relations image theory and extends the theory by emphasizing that individuals' social identity and social dominance motives contribute to such images. One hundred forty-five Lebanese participants completed a survey that assessed their perceptions of U.S.-Lebanese relations, the images they have of the United States, their social identities, and their social dominance orientations. Participants were more likely to hold the barbarian image of the United States than the enemy, imperialist, or ally images. Participants also tended to perceive the United States as having relatively superior power, inferior cultural status, and goals that are incompatible with those of Lebanon. Consistent with image theory predictions, this constellation of structural perceptions was associated with stronger endorsement of the barbarian image. Furthermore, participants were more likely to endorse the barbarian image of the United States the more they identified with Arabs and Palestinians, the less they identified with Christians and the Western world, and the lower their social dominance orientation. Results highlight the importance of considering both structural characteristics and individual motives underlying international images and demonstrate the need for scholars to move beyond the enemy image of nations when describing international relations.     

Math weaknesses in survivors of acute lymphoblastic leukemia compared to healthy children.

Difficulties in math are the most frequently reported area of academic deficit in survivors of acute lymphoblastic leukemia (ALL) and the most frequent academic complaint among parents of ALL survivors. However, previous studies that included measures of math skills have been limited by the use of only a single measure of math skills, most often a measure of written calculations, without any assessment of math reasoning or math application skills. Further, the nature of these math difficulties has not been adequately investigated. The purpose of this study was to examine the performance of ALL survivors using multiple measures of math skills. Performance was compared to a group of healthy controls matched for age and sex as well as to normative levels. Other measures of neuropsychological function were also administered, and the relationships between these measures and the math measures were explored. Converging evidence for math difficulties in ALL survivors compared to healthy controls and normative levels was found. While ALL survivors generally performed within the average range on measures of math skills, math performance was mostly related to memory function and dominant-hand psychomotor speed. By contrast, math performance of healthy children was mostly related to basic reading skills and visual-motor integration. These findings shed light on the nature of math difficulties in ALL survivors and have implications for intervention.

Early language and the development of children's reading skills

There is considerable agreement that vocabulary plays a central role in reading acquisition, but there is less agreement about whether this association is direct or indirect through phonological and print-related knowledge. Longitudinal data from 77 African-American children were analyzed to examine the relationship between language skills, phonological knowledge and print processing skills at pre-kindergarten and kindergarten with reading at pre-kindergarten through second grade. Analyses indicated that home and child care experiences were related to reading indirectly through language and that language and phonological knowledge were both directly related to acquisition of reading skill. This study of African-American children and previous studies of lower- and middle-income children indicate both language and phonological skills play an important role in children becoming successful readers, and that experiences at home and in child care during in early childhood play a role in the acquisition of reading through their enhancement of early language and phonological skills.     

It's All Relative: The Distinction and Prediction of Political Perceptions Across Levels

The current study was designed to extend previous research by determining whether individuals discriminated political activity at 3 organizational levels (at the highest level in the organization, at the level of one's immediate supervisor, and at one's current level). Further, it was hypothesized that levels of political activity would predict work outcomes differentially. Data gathered from 181 police officers provide strong results. Specifically, findings indicate that respondents discriminated political activity at each level and that differential prediction existed. Implications of these findings, strengths and limitations, and avenues for future research are provided.

The Idea of Moral Progress

This paper shows that moral progress is a substantive and plausible idea. Moral progress in belief involves deepening our grasp of existing moral concepts, while moral progress in practices involves realizing deepened moral understandings in behavior or social institutions. Moral insights could not be assimilated or widely disseminated if they involved devising and applying totally new moral concepts. Thus, it is argued, moral failures of past societies cannot be explained by appeal to ignorance of new moral ideas, but must be understood as resulting from refusals to subject social practices to critical scrutiny. Moral philosophy is not the main vehicle for disseminating morally progressive insights, though it has an important role in processes that lead to moral progress. Yet we have grounds for cautious optimism, since progressive moral insights can be disseminated and can, sometimes, have constructive social effects.     

The effects of a laughing versus a nonlaughing model on humor responses in preschool children

Three groups of preschool children, 2–4 years old, were observed individually as they listened to a humorous tape recording either alone (Group 1), or after they had observed a nonlaughing (Group 2) or laughing peer model (Group 3) listen to the tape and then leave. There was a significant difference between the laughing model group and the nonlaughing model group in time spent smiling as well as significant differences in time spent laughing among the no model group, the nonlaughing model group, and the laughing model group. It was concluded that imitation learning plays a role in determining whether or not children will laugh or smile in a humorous situation.
