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.     

Intolerance of uncertainty and insula activation during uncertain reward

Individuals with high intolerance of uncertainty (IU) have been shown to exhibit abnormal threat responding, which may be mediated by hyperactive anterior insula (aINS) response to uncertainty. Research has indicated that individuals with high IU also exhibit abnormal positive valence responding, suggesting that IU may impact responding to uncertainty regardless of the valence of the potential outcome. To date, no study has investigated the neural processes associated with IU and response to uncertain positive stimuli, such as rewards. Therefore, this study was designed to examine the association between individual differences in IU and neural activation during uncertain reward using functional magnetic resonance imaging (fMRI). Thirty-seven adults completed a self-report measure of IU and a reward task during fMRI. Consistent with the threat literature, greater IU was associated with increased aINS activation during uncertain reward. This association was more robust for the prospective IU subscale, a dimension characterized by worry about future events. Together with prior studies, these findings provide evidence that IU is related to abnormal threat and reward responding, and that these deficits may be similarly linked to hyperactive aINS response to uncertainty.     

Integration of spatial information across vision and language

Three experiments investigated whether spatial information acquired from vision and language is maintained in distinct spatial representations on the basis of the input modality. Participants studied a visual and a verbal layout of objects at different times from either the same (Experiments 1 and 2) or different learning perspectives (Experiment 3) and then carried out a series of pointing judgments involving objects from the same or different layouts. Results from Experiments 1 and 2 indicated that participants pointed equally fast on within- and between-layout trials; coupled with verbal reports from participants, this result suggests that they integrated all locations in a single spatial representation during encoding. However, when learning took place from different perspectives in Experiment 3, participants were faster to respond to within- than between-layout trials and indicated that they kept separate representations during learning. Results are compared to those from similar studies that involved layouts learned from perception only.     

Relationships Among Paternal Involvement and Young Children's Perceived Self-Competence and Behavioral Problems

We examined the relationships of father involvement to young children's perceived self-competence and fathers' and mothers' perceptions of their children's internalizing and externalizing behavioral problems. The results indicated that mothers in families in which father involvement is high may have a more positive outlook regarding their child's behavior than do mothers in families in which father involvement is low. Fathers who were highly involved indicated their children have more behavior problems than fathers who were not highly involved. High father involvement was associated with increased children's feelings of paternal acceptance, a factor that plays a role in the development of self-concept and esteem.     

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.     

Time for change: using implementation intentions to promote physical activity in a randomised pilot trial

Objective: A common barrier to exercise is a perceived lack of time. The current pilot study examined the effects of an implementation intention intervention to enhance exercise self-efficacy, increase confidence to exercise when facing time constraints, and increase physical activity in middle-aged adults (n?=?63, aged 35–69). Design: Participants received a pedometer (Fitbit) to objectively measure activity and were randomly assigned to either a control or intervention condition. After a 1-week baseline, the intervention condition received instructions to plan how, where, and when they would add steps to their daily routine to meet their step goal, using personalised schedules and maps. Both groups were contacted nightly via email. Main Outcome Measures: Physical activity (steps and time spent in moderate-to-vigorous activity), goal achievement, exercise self-efficacy, time-relevant exercise self-efficacy and affect. Results: Compared to the control, the intervention condition significantly increased in steps, time spent in moderate-to-vigorous activity, and time-relevant exercise self-efficacy. Goal achievement was related to greater time-relevant exercise self-efficacy and more positive affect at the daily level. Conclusion: Findings suggest that the personalised planning intervention increased physical activity and confidence in achieving physical activity goals under time constraints. Avenues for future directions, especially for producing more sustained effects, are discussed.
