An efficient computerized testing method for the capuchin monkey (<Emphasis Type="Italic">Cebus apella</Emphasis>): Adaptation of the LRC-CTS to a socially housed nonhuman primate species

Even with advances in automated testing techniques, the capuchin monkey (Cebus apella) can be a difficult species to test in the laboratory, given its social/behavioral tendencies and typical activity pattern. Laboratories that maintain social colonies of capuchin monkeys are able to separate and test individuals, but the process can be very effortful and time consuming, and the resulting data can be modest in quantity. The present article describes procedures and apparatuses that were used to train a colony of computer-naive capuchin monkeys to quickly and reliably isolate themselves from group members and interact with a computerized test system in order to produce a large volume of data. Several elements that were important in motivating the monkeys to participate are discussed.     

Impact of school sense of community within a faith-based university: administrative and academic staff perceptions on institutional mission and values

Academic staff (n = 305) and administrative staff (n = 595) at a large urban, Catholic, and religious order teaching university completed on-line school sense of community, social desirability, and mission-identity plus mission-driven activity measures. Partial correlates (controlling for social desirability) indicated that for both faculty and staff a sense of community with co-workers and with administrators were significantly related to mission-identity characteristics of the university. Moreover, regression analyses found that for faculty and staff significant predictors of school sense of community variables were perceptions that the university was innovative and inclusive of pragmatic and risk-taking ideas. For staff but not for faculty, a feeling of Catholic pluralism on campus was a significant predictor of a sense of community with co-workers. These outcomes suggest that employees at faith-based universities may strengthen their school sense of community by institutional practices and programs that foster creating a setting for innovative, inclusive, pragmatic, and risk-taking policies, but not necessarily religious practices on campus.     

How Groups Merge: The Effects of Merger Integration Patterns on Anticipated Commitment to the Merged Organization1

This study examined the influence of merger integration patterns on expectations about the merger process. The integration patterns included the absorb, in which the merged organization closely resembled the acquiring company; the blend, in which features of both companies were maintained, and the combine, in which the organization resembled neither pre-merger company. Undergraduates role-played employees of a merging organization and written scenarios manipulated the integration pattern and membership in the acquired or acquiring organization. Participants' commitment to the merged organization was most favorable in the combine pattern. Path analyses indicated that the relationship between merger integration pattern and organizational commitment is mediated by the conditions of intergroup contact, perceptions of organizational support, organizational unity, and the degree of threat experienced.     

Anxiety responses in a sample of South African Indians

As much cross-cultural anxiety work has focused on ensuring only the semantic equivalence of questionnaires in different languages, this study examines the response characteristics of South African Indians to an anxiety instrument tentatively constructed for this population. Results show that the scale has a fairly high degree of internal consistency, and that certain items were regularly reported to be frequently experienced. Factor analysis of the 26 items reveals a cognitive distress factor, and a possible distinction within the physiological/physical dimension between somatic distress and elevated activity.     

Categorization of Ambiguous Sentences as a Function of a Changing Prosodic Parameter: A Dynamical Approach

The present study investigates the dynamics of changes in interpretation of ambiguous sentences. The sentences used had alternative interpretations with different surface structures (bracketing). Continua were created by systematic manipulation of prosodic cues (relative foot duration), resulting in stimulus sentences that spanned the range between the two interpretations. Continua were presented to subjects who were requested to indicate as quickly as possible which meaning they perceived. The pattern of responses and response times revealed the presence of hysteresis. That is, when the values of prosodic parameters are congruent with both interpretations, the individual's recent history decides which meaning will be perceived. Thus, we can treat this categorization process as a transition from an initially stable meaning that loses stability with variations in prosody (our control parameter). The same underlying dynamics have been observed in studies of perception of syllables and aspects of visual perception. Apart from demonstrating the same characteristics of pattern formation at various levels of cognition, the study points to the usefulness of the dynamical approach in the investigation of language understanding.     

Recall of semantic clusters in primary memory

An experiment is reported which investigated the use of semantic relatedness as a retrieval cue in the primary memory component in a free recall task. Six-word semantically related clusters were placed in the middle and end positions of free recall lists. Retention was measured immediately after the list presentation and after a filled retention interval of 15 sec. Pure primary memory functions were calculated. The results indicated that semantic cues are useful in retrieval from secondary memory but played no part in recall from primary memory.
