What wild primates know about resources: opening up the black box

We present the theoretical and practical difficulties of inferring the cognitive processes involved in spatial movement decisions of primates and other animals based on studies of their foraging behavior in the wild. Because the possible cognitive processes involved in foraging are not known a priori for a given species, some observed spatial movements could be consistent with a large number of processes ranging from simple undirected search processes to strategic goal-oriented travel. Two basic approaches can help to reveal the cognitive processes: (1) experiments designed to test specific mechanisms; (2) comparison of observed movements with predicted ones based on models of hypothesized foraging modes (ideally, quantitative ones). We describe how these two approaches have been applied to evidence for spatial knowledge of resources in primates, and for various hypothesized goals of spatial decisions in primates, reviewing what is now established. We conclude with a synthesis emphasizing what kinds of spatial movement data on unmanipulated primate populations in the wild are most useful in deciphering goal-oriented processes from random processes. Basic to all of these is an estimate of the animal’s ability to detect resources during search. Given knowledge of the animal’s detection ability, there are several observable patterns of resource use incompatible with a pure search process. These patterns include increasing movement speed when approaching versus leaving a resource, increasingly directed movement toward more valuable resources, and directed travel to distant resources from many starting locations. Thus, it should be possible to assess and compare spatial cognition across a variety of primate species and thus trace its ecological and evolutionary correlates.

Reflexive Communities: The Non-Western Church as Healing Community

Many non-Western Christian communities have experienced terrible human rights violations at the hands of fellow citizens, civil authorities, or rebel groups, Christian or otherwise. This article presents a brief and practical model of healing that attempts to remain consistent with the general characteristics of non-Western social realities. It suggests that rather than relying on the paucity of professional therapies offered in those contexts, non-Western churches themselves can become harbingers of healing for the traumatized community. By blending social theory with biblical narratives, this article proffers an example of how healing can take place within sociocentric communities.     

Impact of Co-Therapy Teams on Client Outcomes and Therapist Training in Marriage and Family Therapy

This study of 33 student therapists, 402 client systems, and three supervisors tested the efficacy of using student co-therapy teams as an aspect of clinical training in a marriage and family therapy program. This study utilizes both quantitative and qualitative methodology. Two research questions were addressed: “Do different pairings of co-therapists affect client outcomes?” and “Is co-therapy a viable option for a training program?” The results indicate that client outcomes using co-therapy are at least as effective as treatment using one therapist and in some circumstances produce more positive outcomes for both clients and student therapists.     

On exploring meanings: Combining humanistic and career psychology theories in counselling

The notion of meaning is considered a significant construct in both humanistic psychology and vocational psychology. These two psychological disciplines appear to share some philosophical common ground with respect to the role of meaning making and meaning interpretation in people's life career experiences. This paper intends to take a look at such shared conceptual foundation, and examine the feasibility in incorporating the humanistic meaning construct into career psychology. Career counselling implications are discussed.     

Applying family therapy theories to Asian/Pacific Americans

This paper introduces a framework by which the structural and communicative-interactive theories of family therapy can be logically and systematically applied with Asian/Pacific American families. It begins with an introduction to Schutz's FIRO theory and model. Application and relevance to work with Asian/Pacific American families is discussed and illustrated with a case application.Paper originally presented at the 1987 annual program meeting of the Council on Social Work Education, St. Louis, Missouri, March 8, 1987.     

Behavioral consequences of song learning: Discrimination of song types by male white-crowned sparrows

The functional significance of learned population differences in male song in the white-crowned sparrow was explored in natural populations using playback tests. Laboratory results have shown that learning of the population-specific song seems to take place in early life and is strongly dependent upon the nature of the auditory experience at that time. However, the varied results of recent studies make it difficult to reach a confident conclusion about the ecological functions of song learning. The present research took advantage of naturally occurring variation in the differences between songs of adjacent populations to determine a function relating degree of difference in song to intensity of territorial singing elicited. Applying a typological evaluation of syllable structure to the four segments of the song allowed a crude quantitative ranking of the differences between local songs and playback stimuli. These results, together with those of other studies, suggest a unimodal aggressive response function of males to songs of other males. A maximum response to songs slightly different from the local song environment suggests that male exclusion based upon acquired song components may contribute to the maintenance of discrete and stable song dialects.     

Verb frame preferences: Descriptive norms

This paper presents normative data about the frequency with which college students construct sentences with different syntactically defined frames for 127 English verbs. The norms are intended to be of use to experimenters in preparing materials to study sentence comprehension.
