The repertoire and intentionality of gestural communication in wild chimpanzees

A growing body of evidence suggests that human language may have emerged primarily in the gestural rather than vocal domain, and that studying gestural communication in great apes is crucial to understanding language evolution. Although manual and bodily gestures are considered distinct at a neural level, there has been very limited consideration of potential differences at a behavioural level. In this study, we conducted naturalistic observations of adult wild East African chimpanzees (Pan troglodytes schweinfurthii) in order to establish a repertoire of gestures, and examine intentionality of gesture production, use and comprehension, comparing across manual and bodily gestures. At the population level, 120 distinct gesture types were identified, consisting of 65 manual gestures and 55 bodily gestures. Both bodily and manual gestures were used intentionally and effectively to attain specific goals, by signallers who were sensitive to recipient attention. However, manual gestures differed from bodily gestures in terms of communicative persistence, indicating a qualitatively different form of behavioural flexibility in achieving goals. Both repertoire size and frequency of manual gesturing were more affiliative than bodily gestures, while bodily gestures were more antagonistic. These results indicate that manual gestures may have played a significant role in the emergence of increased flexibility in great ape communication and social bonding.     

Dissociable yet tied inhibitory processes: The structure of inhibitory control

Cognitive and neural models have proposed the existence of a single inhibitory process that regulates behavior and depends on the right frontal operculum (rFO). The aim of this study was to make a contribution to the ongoing debate as to whether inhibition is a single process or is composed of multiple, independent processes. Here, within a single paradigm, we assessed the links between two inhibitory phenomena—namely, resistance to involuntary visual capture by abrupt onsets and resolving of spatial stimulus–response conflict. We did so by conducting three experiments, two involving healthy volunteers (Exps. 1 and 3), and one with the help of a well-documented patient, R.J., with selectively weakened inhibition following a lesion of the rFO. The results suggest that resistance to capture and stimulus–response conflict are independent, because (a) additive effects were found (Exps. 1 and 3), (b) capture did not correlate with compatibility effects (Exp. 1), (c) dual tasking affected the two phenomena differently (Exp. 3), and (d) a dissociation was found between the two in patient R.J. (Exp. 2). However, the results also show that these two phenomena may share some processing components, given that (a) both were affected in patient R.J., but to different degrees (Exp. 2), and (b) increasing the difficulty of dual tasking produced an increasingly negative correlation between capture and compatibility (Exp. 3), which suggests that when resources are withdrawn from the control of the former, they are used to control the latter.     

Integrating Theories of Psychological Needs‐as‐Requirements and Psychological Needs‐as‐Motives: A Two Process Model

Two conceptions of psychological needs predominate within contemporary motivational science. Motive disposition theory conceives of needs as behavioral motives which direct behavior (needs‐as‐motives), while self‐determination theory conceives of needs as universally required experiences for optimal functioning (needs‐as‐requirements). Until recently, these perspectives on psychological needs have proceeded without much intersection, despite the fact that they address the same fundamental concept. Here we summarize the Two Process Model of Psychological Needs, which attempts to bridge these two conceptions. We argue that psychological needs are best defined as tendencies to seek out certain basic types of psychosocial experiences, to a somewhat varying extent across individuals, and to feel good and thrive when those basic experiences are obtained, to the same extent across individuals. We suggest that this definition allows a reconciliation of needs‐as‐motives and needs‐as‐requirements perspectives and a more consilient science of human motivation. Empirical support for the TPM is also summarized.     

Precipitating Circumstances of Suicide among Active Duty U.S. Army Personnel Versus U.S. Civilians, 2005–2010

To help understand suicide among soldiers, we compared suicide events between active duty U.S. Army versus civilian decedents to identify differences and inform military prevention efforts. We linked 141 Army suicide records from 2005 to 2010 to National Violent Death Reporting System (NVDRS) data. We described the decedents’ military background and compared their precipitators of death captured in NVDRS to those of demographically matched civilian suicide decedents. Both groups commonly had mental health and intimate partner precipitating circumstances, but soldier decedents less commonly disclosed suicide intent.     

Practical Matters and Ultimate Concerns, “Doing,” and “Being”: A Diary Study of the Chaplain's Role in the Care of the Seriously Ill in an Urban Acute Care Hospital

Systematic observational studies of the chaplain's role and function in the secular health‐care setting are few. With an episode‐based diary recorded on handheld digital tablets, palliative care chaplains at a large urban hospital with a diverse patient population recorded details of patient visits in near‐real time. Cluster analysis revealed groups of activities we called "doing" and "being," and conversation topics of "practical matters" and "ultimate concerns”; chaplains were most satisfied with visits that involved all of these. Chaplains offer patients and families a space to express significant concerns; however, visits with spiritual or religious activities or topics were relatively rare. Broad quality of life concerns are central to the evolving professional role of chaplains in the secular setting of the modern hospital.     

Counselor Cognitive Complexity: Correlating and Comparing the Myers–Briggs Type Indicator With the Role Category Questionnaire

This study examined personality types and cognitive complexity levels in counseling trainees. Data from graduate‐level counseling students were collected (N = 74). Cognitive complexity levels were measured using the Role Category Questionnaire (RCQ) and personality types were measured using the Myers–Briggs Type Indicator. Results showed that perceiving types tended to perform better on the RCQ than judging types, and that those who were highly differentiated in all preferences overall tended to score higher on the RCQ. These findings have implications for employment and career counselors and their clients who are, or aspire to be, in the helping profession.
