Critical individualism: Whitehead's metaphysics and critique of liberalism

Conclusion Whitehead's metaphysics contains an accurate portrayal of concrete human existence - one which can serve as a ground for criticizing the abstractions into which liberalism has fallen. His critical individualism, his insistence both on the individual as the seat of all value and on our essential connectedness to one another in modern society, is a call for liberalism to restore concrete meaning to its fundamental notions of individuality and freedom. However, his suggestions that the core values of liberalism can be actualized if we but reaffirm Plato's ancient equation of knowledge with virtue rests on an optimism that is difficult to sustain apart from a compensatory metaphysical dogma. We can appropriate Whitehead's criticism of liberalism, but if we can no longer convince ourselves of a metaphysical vision that supports faith in Plato's equation, we must look elsewhere for suggestions as to how liberalism can be revitalized.     

Attentional inhibition or paracontrast?

In visual search experiments using asynchronous presentation of target and distractors, a robust and unexpected inhibition of reaction time was observed for the discrimination of a temporally trailing target. A number of experiments were required to determine the source of this inhibition. These experiments eliminated the possibilities that the inhibition might be a manifestation of three attentional processes: inhibition of return, attentional dwell time, or attentional capture by the temporally leading item. Other experiments eliminated the possible preattentional process of the temporal impulse response, the psychological refractory period, and a response inhibition. The characteristics of this inhibition lead to the conclusion that it is a manifestation of paracontrast.     

Dichoptic and dichotic micropattern discrimination

Ss compared two rapidly successive, brief, discriminably different stimulus elements, called a micropattern, with a second micropattern composed of the same two stimulus elements presented in reverse temporal order. Discriminations could be made between two such micropatterns in the monaural (monocular) as well as in the dichotic (dichoptic) modes of presentation. Discrimination between micropatterns was based on the perceptual dominance of the temporally trailing stimulus element in both modalities and in both modes of presentation. While monaural (monocular) micropattern discrimination is significantly superior to dichotic (dichoptic) discrimination, the existence of dichotic (dichoptic) discrimination demonstrates that no essential peripheral process is required for micropattern discrimination.     

Central auditory processing. VI. Detecting ear dominance by evoked potentials

An electrophysiological method is described for measuring the direction and strength of a subject's ear dominance for pitch using the P3 component of event-related potentials. Results of these experiments reveal that the P3 can be used effectively for these measures in man.     

Do you believe happiness can change? An investigation of the relationship between happiness mindsets,well-being,and satisfaction

Three studies (N = 794) examined if beliefs about the malleable nature of happiness (growth mindsets) are associated with well-being and if this well-being had downstream implications for satisfaction with one’s relationships (Studies 1–3), health (Study 3), and job (Study 3). In Study 1 (N = 277), happiness growth mindsets were associated with greater well-being and greater relationship satisfaction. In Study 2 (N = 337), using an experimental paradigm and serial mediation, encouraging growth mindsets led to stronger beliefs in the changeable nature of happiness, which in turn was associated with subjective well-being, and, finally, relationship satisfaction. In Study 3 (N = 180), we replicated the downstream effects of growth mindsets of happiness on well-being and subsequently on relationship satisfaction and extended these serial mediation effects to health and job satisfaction. We discuss the implications of happiness mindsets.     

Dual-task interference in visual working memory: A limitation in storage capacity but not in encoding or retrieval

The concurrent maintenance of two visual working memory (VWM) arrays can lead to profound interference. It is unclear, however, whether these costs arise from limitations in VWM storage capacity (Fougnie & Maro is, 2006) or from interference between the storage of one visual array and encoding or retrieval of another visual array (Cowan & Morey, 2007). Here, we show that encoding a VWM array does not interfere with maintenance of another VWM array unless the two displays exceed maintenance capacity (Experiments 1 and 2). Moreover, manipulating the extent to which encoding and maintenance can interfere with one another had no discernable effect on dual-task performance (Experiment 2). Finally, maintenance of a VWM array was not affected by retrieval of information from another VWM array (Experiment 3). Taken together, these findings demonstrate that dual-task interference between two concurrent VWM tasks is due to a capacity-limited store that is independent from encoding and retrieval processes.     

The Perils of Feeling In-Between: The Experiences of Emerging Adult Novice Teachers

This paper explores whether emerging adults who are also new teachers experience any negative consequences connected with the “in-between” feeling of emerging adulthood. A survey was administered to 58 first-year teachers to identify teachers who were satisfied and dissatisfied with their classroom management experiences. A subsample of 16 teachers were interviewed to elicit their narratives of becoming adult and becoming a teacher. Teachers used three frameworks to define and describe the experience of adulthood. Completing the Adult Checklist is a global status identified by the attainment of social role markers associated with adulthood. Feeling Adult is a subjective experience of adulthood that varies across contexts and is dependent on comparisons of the self with others. The third framework, Seen As Adult, is the establishment of adult status in the perceptions of significant others. Teachers dissatisfied with their classroom management were found to say that they did not Feel Adult in their classrooms and that they were not Seen As Adult by their students or other teachers. Implications are discussed for the study of difficulties encountered by emerging adults who take on roles in which they are expected to act in an adult capacity.     

Attachment avoidance to God exacerbates the negative effect of tangible resource loss on psychological resource loss

The present study examined the impact of losing tangible resources on psychological resources in a sample of college students (n?=?160) affected by Hurricane Katrina. The data was collected approximately five months after the storm. Based on conservation of resources theory, we tested whether the loss of tangible resources (e.g., food, water) would be positively related to the loss of psychological resources (e.g., optimism, hope), and whether this association would be exacerbated by having an insecure (anxious or avoidant) attachment to God. As predicted, loss of tangible resources was related to the loss of psychological resources, and this relationship was amplified in participants who had an avoidant attachment to God. We conclude by discussing implications of the present study and areas for future research.     

Practice in visual search produces decreased capacity demands but increased distraction

Lavie (1995) proposed a load account of selective attention, which holds that spare capacity is involuntarily allocated to the processing of irrelevant stimuli. In support of this account, Lavie and Cox (1997) combined a letter search task with a flanker task and found that increasing load (search set size) resulted in decreased interference from an irrelevant distractor letter. In three experiments using a very similar procedure, we varied distractor location and distractor distinctiveness and observed that as load increased (from set size 2 to set size 6), there was a consistent reduction in interference. Critically, we addressed a fundamental hypothesis derived from the load account-that practice reduces capacity demands. This hypothesis leads to the rather counterintuitive prediction that as performance improves with practice, distractor processing should actually increase. Indeed, we found that interference in a high-load condition (set size 6), but not in a low-load condition (set size 2), did increase with practice. We describe a two-stage dilution account of attention that accommodates these results.
