Carry on: spontaneous object carrying in 13-month-old crawling and walking infants

Carrying objects requires coordination of manual action and locomotion. This study investigated spontaneous carrying in 24 walkers who were 13 months old and 26 crawlers who were 13 months old during 1-hr, naturalistic observations in the infants' homes. Carrying was more common in walkers, but crawlers also carried objects. Typically, walkers carried objects in their hands, whereas crawlers multitasked by using their hands simultaneously for holding objects and supporting their bodies. Locomotor experience predicted frequency of carrying in both groups, suggesting that experienced crawlers and walkers perceive their increased abilities to handle objects while in motion. Despite additional biomechanical constraints imposed by holding an object, carrying may actually improve upright balance: Crawlers rarely fell while carrying an object, and walkers were more likely to fall without an object in hand than while carrying. Thus, without incurring an additional risk of falling, spontaneous carrying may provide infants with new avenues for combining locomotor and manual skills and for interacting with their environments.     

Heidegger and the Essence of Dasein

Being and Time argues that we, as Dasein, are defined not by what we are, but by our way of existing, our “existentiell possibilities.” I diagnose and respond to an interpretive dilemma that arises from Heidegger's ambiguous use of this latter term. Most readings stress its specific sense, holding that Dasein has no general essence and is instead determined by some historically contingent way of understanding itself and the meaning of being at large. But this fails to explain the sense in which Being and Time is a work of fundamental ontology, concluding in Heidegger's claim to have found the meaning of Dasein's being in the concept of originary temporality. On the other hand, readings that stress the general sense of “existentiell possibilities” find Heidegger on a fruitless quest for the transcendental conditions necessary for Dasein's existence, which seems to founder on the claims that Dasein is constitutively thrown, factical, and “in‐each‐case‐mine” [jemeinig]. Both readings are problematic and, I contend, result from a failure to disambiguate and explain the ontologically unique relationship between the specific and general aspects of Dasein's essence. I argue that we can better explain this relationship, Heidegger's method for investigating it, and the sense in which Dasein has an essence that is open to philosophical investigation, if we read Being and Time's ontology of Dasein in terms of what Anton Ford calls “categorial” genus‐species relationships.     

Originary Temporality and Existential Commitment: A Defense of Heidegger's A Potiori Claim

Being and Time's fundamental ontoogy and existentialism both rest on the A Potiori Claim, which states that originary temporality is, although non‐sequential, a genuine and basic concept of time from which we derive our more ordinary, sequential concept of time. In this paper, I develop a new reading and defense of this claim against the readings of William Blattner, which ties originary temporality too tightly to the particular roles and identities we live out and must therefore find Heidegger's project a failure, and Tony Fisher, who implies that our various roles and identities hang together in time in a merely accidental and non‐rational way. On my reading, originary temporality is the structure of Dasein's characteristic activity of existential commitment. Through this activity, we each work out, in our own case, what it takes to embody the capacity for sense‐making, at all. Here, the non‐sequentiality of originary temporality reflects the way in which commitments are revised and sustained through time, while the sequence of nows derives from our need to embody our commitment in a single life that negotiates among the practical demands that our various identities make of us.     

Facilitating Acceptance of Organizational Change: The Importance of Self‐Determination1

Self‐determination theory (Deci & Ryan, 1985, 1987, 1991) proposes that internalization can be facilitated by supporting a person's autonomy. Autonomy support can be achieved using 3 means: giving a rationale for doing a task, offering some choice about how to do the task, and acknowledging feelings about the task. We examined the effects of these 3 factors on acceptance of change in a work organization. Employees from a large Canadian telecommunications company that was in the midst of profound transformation completed scales on 2 separate occasions. Cross‐sectional and longitudinal results demonstrated that the 3 factors facilitated acceptance of organizational change, with substantial effect sizes. Implications for successful organizational transformation are discussed.     

Persistent symptoms among survivors of Hodgkin's disease: an explanatory model based on classical conditioning.

Persistent symptoms of nausea, distress, and vomiting triggered by reminders of cancer treatment were examined among 273 Hodgkin's disease survivors, 1 to 20 years posttreatment. Prevalence rates were high for distress and nausea but low for vomiting. Retrospective report of anticipatory symptoms during treatment was the strongest predictor of persistent symptoms, suggesting that treatment-induced symptoms are less likely to persist if conditioning does not occur initially. Time since treatment was also a significant predictor, with patients more recently treated more likely to experience persistent symptoms. Thus, an explanatory model based on classical conditioning theory successfully predicted presence of persistent symptoms. Symptoms also were associated with ongoing psychological distress, suggesting that quality of life is diminished among survivors with persistent symptoms. Recommendations for prevention and treatment of symptoms are discussed.     

Reliability and validity of the Multiple Affect Adjective Check List - Revised

A recent factor analysis of the Multiple Affect Adjective Check List (MAACL) changed the Anxiety, Depression, and Hostility scales from bipolar to unipolar scales and added two new scales: Positive Affect and Sensation Seeking. Internal reliability of the MAACL-R scales, computed for normal and patient samples, was adequate for state and trait forms except for Sensation Seeking. Test-retest reliability in college students was higher for the trait form with retest intervals of from 2 to 8 weeks than for the state form with retest intervals of from 2 to 5 days. The pattern of correlations among self-, peer, and counselor ratings and the MAACL-R scales for normal and patient samples indicates improved discriminant validity and equally good convergent validity as the old scales. The use of standard scores that are indexed to the number of items checked reduced scale intercorrelations by controlling the acquiescence set.The financial support of the Weldon Springs Endowment Fund, University of Missouri at Kansas City, toward the completion of this research project is gratefully acknowledged.     

Beliefs m Realistic and Unrealistic Control: Assessment and Implications

ABSTRACT Scales were constructed to measure perceived control over controllable events (realistic control) and perceived control over uncontrollable events (unrealistic control). Internal reliability, test-retest reliability, and discriminant validity of both scales were adequate. Study 1 measured perceived personal control over hassles that judges rated on general controllability. For hassles very high in controllability, perceived personal control was related to belief in realistic control but not to belief in unrealistic control; for hassles very low in controllability, perceived personal control was related to belief in unrealistic control but not to belief in realistic control. Study 2 showed that participants high in unrealistic control belief (but not those high in realistic control belief) persevered more on a task that was in part uncontrollable. Study 3 showed that the combination of low realistic control belief and high unrealistic control belief predicted poorer future health, particularly for participants who have reported the experience of many negative events and/or hassles. The conditions under which unrealistic control results in maladaptive outcomes are discussed.
