Generalization of the disruptive effects of alternative stimuli when combined with target stimuli in extinction

Differential‐reinforcement treatments reduce target problem behavior in the short term but at the expense of making it more persistent long term. Basic and translational research based on behavioral momentum theory suggests that combining features of stimuli governing an alternative response with the stimuli governing target responding could make target responding less persistent. However, changes to the alternative stimulus context when combining alternative and target stimuli could diminish the effectiveness of the alternative stimulus in reducing target responding. In an animal model with pigeons, the present study reinforced responding in the presence of target and alternative stimuli. When combining the alternative and target stimuli during extinction, we altered the alternative stimulus through changes in line orientation. We found that (1) combining alternative and target stimuli in extinction more effectively decreased target responding than presenting the target stimulus on its own; (2) combining these stimuli was more effective in decreasing target responding trained with lower reinforcement rates; and (3) changing the alternative stimulus reduced its effectiveness when it was combined with the target stimulus. Therefore, changing alternative stimuli (e.g., therapist, clinical setting) during behavioral treatments that combine alternative and target stimuli could reduce the effectiveness of those treatments in disrupting problem behavior.     

The roles of different executive functioning skills in young children’s mental computation and applied mathematical problem-solving

This study investigated the relationships of four executive functioning skills (including verbal working memory, spatial working memory, inhibitory control, and cognitive flexibility) with young children’s mental computation and applied mathematical problem-solving. Two hundred and twenty-five Chinese kindergarteners were tested with a battery of general cognitive, executive functioning and mathematics skills. Results showed that when children’s age, gender, non-verbal intelligence, and listening comprehension skills were controlled, verbal working memory and cognitive flexibility were significant correlates of mental computation, whereas verbal working memory, spatial working memory, and cognitive flexibility were significant correlates of applied mathematical problem-solving. Inhibitory control was not significantly associated with the two domains of mathematics under investigation. The findings highlight the differential roles of different executive functioning skills in early mathematical skills and offer practical implication for helping young children in learning complex mathematical skills.     

Performance as a source of perceived control

The purpose of this experiment was to examine the effects of choice and environmental control on the development of the perception of control. The results showed that the perception of control develops from an opportunity to make choices. More deliberate (slower) decisions resulted in an increase in the perception of control, and these perceptual effects generalized to a dice-throwing task over which no choice was possible. A model was examined which assumes that subjects monitor their own behavior with the result that more thoughtful decisions lead subjects to infer higher levels of control.A portion of these results was presented at the annual meeting of the South Eastern Psychological Association, 1983. This research was supported in part by the VA Medical Research Services, the U.S. Army Human Engineering Laboratory, and Grant AGO 2300 from the National Institute on Aging.

Tightness-Looseness Revisited: Some Preliminary Analyses in Japan and the United States

The construct of tightness-looseness is considered to be important in differentiating cultures (Pelto, 1968; Triandis, 1977, 1989). The objective of the present paper is to advance understanding of this construct. Specifically, we present a conceptual framework for the construct and formulate some general research hypotheses derived from our conceptualization. In addition, we examine one of our general hypotheses that cultures differing in the tight-loose dimension will differ in the way language is used. Using a data set from Osgood, May, and Miron (1975), we compared the Japanese and the US samples of this study and found evidence supporting the hypothesis that Japan is a tighter culture, as compared to the USA. In addition to studying the construct of individualism-collectivism, we suggest that tightness-looseness is an important cultural dimension that can explain and predict cultural differences in many kinds of social behaviour.     

Multimethod Probes of Allocentrism and Idiocentrism

Collectivism and individualism are cultural syndromes that have some common cores. Allocentrism and idiocentrism are constructs at the individual level that correspond to collectivism and individualism respectively at the cultural level. In two studies, the first with American (from Illinois) and the second with Japanese subjects, we examined the best way to measure these common cores. We also present the recommended items in two appendices, and provide information about the reliability and convergent validity of the items in these appendices. Finally, we tested the hypothesis that women will be more allocentric than men. We obtained only directional support in the US but fairly good support of this hypothesis in Japan.     

Mexican-American migrant students' academic success: sociological and psychological acculturation.

This study attempted to describe and compare academically successful and academically unsuccessful high-risk Mexican-American migrant high school students. The two groups were compared on sociological and psychological indicators of acculturation, urbanization, and socioeconomic status (SES). It was hypothesized that the successful group would have higher SES, be more acculturated, urbanized, and psychologically adjusted to modern value systems, and have higher occupational aspirations and expectations than the unsuccessful group. In addition, their world views were compared by exploring early recollection data. The results showed that the unsuccessful group came from families that were larger, poorer, more rural, and more "foreign" (i.e., more parents and children born in Mexico) than the successful students' families. Regarding the psychological indicators of acculturation, the successful group was found to score higher on modernism, to be more stably acculturated, to have a clearer sense of themselves, to have higher occupational aspirations and expectations, and tended to desire jobs with greater responsibility and stability than did the unsuccessful group.     

Evaluating Rehabilitation Caseload Management Skills Through Computer Simulations

In this article the authors report on the development and validation of a computer-based rehabilitation caseload management simulation as a teaching and evaluation tool in counselor education. The computer simulation was administered to 18 rehabilitation students and 18 rehabilitation counselors. Their performance on the simulation was evaluated using six caseload management performance indicators. These performance indicators, derived from the computer simulation, were found to be effective in differentiating the student group from the experienced counselor group using discriminant analysis. Implications for the use of computer simulations in rehabilitation counselor education and future research directions are discussed.
