Resistance to disruption in a classroom setting

Substantial experimental evidence indicates that behavior reinforced on a denser schedule is more resistant to disruption than is behavior reinforced on a thinner schedule. The present experiment studied resistance to disruption in a natural educational environment. Responding during familiar activities was reinforced on a multiple variable-interval (VI) 7-s VI 30-s schedule for 6 participants with developmental disabilities. Resistance to disruption was measured by presenting a distracting item. Response rates in the disruption components were compared to within-session response rates in prior baseline components. Results were consistent with the predictions of behavioral momentum theory for 5 of 6 participants.     

Similarity and difference in the processing of same- and other-race faces as revealed by eye tracking in 4- to 9-month-olds

Fixation duration for same-race (i.e., Asian) and other-race (i.e., Caucasian) female faces by Asian infant participants between 4 and 9 months of age was investigated with an eye-tracking procedure. The age range tested corresponded with prior reports of processing differences between same- and other-race faces observed in behavioral looking time studies, with preference for same-race faces apparent at 3 months of age and recognition memory differences in favor of same-race faces emerging between 3 and 9 months of age. The eye-tracking results revealed both similarity and difference in infants’ processing of own- and other-race faces. There was no overall fixation time difference between same race and other race for the whole face stimuli. In addition, although fixation time was greater for the upper half of the face than for the lower half of the face and trended higher on the right side of the face than on the left side of the face, face race did not impact these effects. However, over the age range tested, there was a gradual decrement in fixation time on the internal features of other-race faces and a maintenance of fixation time on the internal features of same-race faces. Moreover, the decrement in fixation time for the internal features of other-race faces was most prominent on the nose. The findings suggest that (a) same-race preferences may be more readily evidenced in paired comparison testing formats, (b) the behavioral decline in recognition memory for other-race faces corresponds in timing with a decline in fixation on the internal features of other-race faces, and (c) the center of the face (i.e., the nose) is a differential region for processing same- versus other-race faces by Asian infants.     

Priming a new identity: self-monitoring moderates the effects of nonself primes on self-judgments and behavior

When a construct is primed, people often act in construct-consistent ways. Several accounts for this effect have been offered, including ideomotor theory and a social functional perspective. The authors tested an additional perspective, the Active-Self account, whereby primes can temporarily alter self-perceptions. In Study 1, non-African American participants reported feeling more aggressive on an implicit measure following an African American prime. In Study 2, participants reported feeling luckier on an implicit measure following a number 7 (vs. 13) prime. In both studies, these effects were obtained only for low self-monitors, who are more likely to change self-conceptions in response to diagnostic self-information and to use their internal states in guiding behavior. Study 3 showed that low self-monitors also show larger behavioral effects of primes.     

Controlling racial prejudice: social-cognitive goals affect amygdala and stereotype activation

The malleability of stereotyping matters in social psychology and in society. Previous work indicates rapid amygdala and cognitive responses to racial out-groups, leading some researchers to view these responses as inevitable. In this study, the methods of social-cognitive neuroscience were used to investigate how social goals control prejudiced responses. Participants viewed photographs of unfamiliar Black and White faces, under each of three social goals: social categorization (by age), social individuation (vegetable preference), and simple visual inspection (detecting a dot). One study recorded brain activity in the amygdala using functional magnetic resonance imaging, and another measured cognitive activation of stereotypes by lexical priming. Neither response to photos of the racial out-group was inevitable; instead, both responses depended on perceivers' current social-cognitive goal.

Binding in short-term visual memory

The integration of complex information in working memory, and its effect on capacity, shape the limits of conscious cognition. The literature conflicts on whether short-term visual memory represents information as integrated objects. A change-detection paradigm using objects defined by color with location or shape was used to investigate binding in short-term visual memory. Results showed that features from the same dimension compete for capacity, whereas features from different dimensions can be stored in parallel. Binding between these features can occur, but focused attention is required to create and maintain the binding over time, and this integrated format is vulnerable to interference. In the proposed model, working memory capacity is limited both by the independent capacity of simple feature stores and by demands on attention networks that integrate this distributed information into complex but unified thought objects.     

Motivation,altruism, and generalized compliance: a field study of organizational citizenship behaviors

This study tests the relations among five sources of motivation and two organizational citizenship behaviors. 175 employees from 31 locations of two agriculturally based companies completed the Motivation Sources Inventory and were rated by their supervisors for demonstrated organizational citizenship behaviors. There were significant positive correlations for employees' Self-concept-Internal Motivation with Altruistic Behavior of employees; while employees' Self-concept-External Motivation showed a significant negative relation with Altruistic Behavior by employees. Surprisingly, no correlation between employees' Goal Internalization Motivation and Altruistic Behavior by employees was found. Interpretation of these findings and further research are suggested.     

Philosophy as a missing link between values and behavior

Despite the persistence of social scientists, evaluating the relationship between values and behavior has not yielded clear results. Here, a model is proposed to conceptualize and measure a person's operating philosophy. This assesses a different level of the value structure within personality from separate values or clusters of values; it is the evaluative structure within which a person's values exist. Building on major philosophies, such as utilitarianism or humanism, the model assumes that a person has a predominant Pragmatic, Intellectual, or Human Operating Philosophy. In a sample of 801 subjects, each of these operating philosophies had significant associations with a variety of the expected behaviors evident in work and graduate school, such as initiative and empathy, as well as learning styles, skills, and flexibility. Interpretation of the results is offered as a way to understand the relationship between people's values or beliefs and their behavior and approach to learning.
