AimTo analyse the peripheral extent of choroidal circulation using ultra-widefield (UWF) indocyanine green angiography (ICGA) in healthy eyes.MethodsUWF ICGA images of 55 eyes of 36 healthy subjects were captured using the Optos California (Optos, Dunfermline, United Kingdom) in this prospective observational study. Images were analysed to locate the peripheral extent of the visible choroidal circulation, and the boundary was marked in ImageJ (v1.52). Each pixel annotated as the border of the choroidal circulation was projected individually to its anatomically correct location on the three-dimensional model eye, and spherical trigonometry was applied (using the Optos software) to calculate its respective radial distance from the centre of the optic disc in metric units (corrected by stereographic projection) for each quadrant.ResultsThe mean area of the peripheral extent was estimated to be 893.2 mm2 (95% CI: 844.2 to 942.3 mm2). The mean distance (range) of this boundary from optic nerve centre was 18.22 mm (95% CI: 14.0 to 23.14 mm). Multiple regression analysis with age, gender, axial length or ethnicity showed no relationship. There was excellent inter-grader reproducibility, with intraclass correlation coefficients of 0.95 (95% CI: 0.80 to 0.99, ppConclusionsThe peripheral choroidal boundary may be defined using UWF ICGA. Knowledge of the normal extent and its variability is essential to understand the impact of disease on the choroidal vasculature.

Purpose To study the number and distribution of vortex ampullae in healthy eyes using ultra-wide field (UWF) indocyanine green angiography (ICGA). Design Prospective, observational study. Participants Thirty-six eyes of 36 healthy participants with no evidence of ocular or systemic disease. Methods The UWF ICGA images (central and peripheral steered) were captured using the Optos California (Optos, Dunfermline, United Kingdom) instrument. The images were projected stereographically to correct for peripheral distortion and obtain accurate measurements. All images were graded and analyzed for number, location, and distance of the vortex vein ampullae from the center of optic nerve. Main Outcome Measures Mean number and the distance of ampullae from the center of optic nerve in all quadrants. Results The mean number of ampullae observed by UWF ICGA was 8.0±2.1 (range, 5–13). The mean distance of a vortex vein ampulla from the optic nerve was 14.2±1.1 mm (range, 10.3–17.7 mm). The frequency of ampullae was higher in the superior and inferior quadrants than the nasal and temporal quadrants. Ampullae were never observed in the 3- or 9-o’clock meridians. Multiple regression analysis showed no relationship with age, gender, axial length, or ethnicity. Excellent intergrader reproducibility was found between graders with an intraclass correlation coefficient (distance measurements: intraclass correlation coefficient, 0.99; 95% CI, 0.979–0.999; P Conclusions The number of discrete vortex vein ampullae that can be discerned by UWF ICGA in healthy individuals is greater frequently and substantially than the 4 that are traditionally thought to drain the major quadrants. Considerable variability in the number and position of the ampullae may be apparent in healthy individuals.

Metamotivation research suggests that people may be able to modulate their motivational states strategically to secure desired outcomes (Scholer & Miele, 2016). To regulate one's motivational states effectively, one must at minimum understand (a) which states are more or less beneficial for a given task and (b) how to instantiate these states. In the current article, we examine to what extent people understand the self-regulatory benefits of high-level versus low-level construal (i.e., motivational orientations toward abstract and essential vs. concrete and idiosyncratic features). Seven experiments revealed that participants can distinguish tasks that entail high-level versus low-level construal. Further, participants recognized the usefulness of preparatory exercises with which to instantiate high-level versus low-level construal for task performance, and this knowledge predicted behavioral choices. This research highlights novel insights that the metamotivational approach offers to research on construal level theory and, more broadly, to the study of self-regulation.

Although dual-process or divided-mind models of self-control dominate the literature, they suffer from empirical and conceptual challenges. We propose an alternative approach, suggesting that self-control can be characterized by a fragmented part versus integrated whole dynamic. Whereas responses to events derived from fragmented parts of the mind undermine self-control, responses to events derived from integrated wholes enhance self-control. We review empirical evidence from psychology and related disciplines that support this model. We, moreover, discuss the implications of this work for psychology, neuroscience, economics, and philosophy. In particular, we highlight how this model addresses many of the conceptual and empirical short-comings of divided-mind models. We suggest that understanding self-control as the interplay between fragmented parts versus integrated wholes, moreover, provides novel insights and testable new hypotheses.

Research indicates that inducing high-level construal (processing that highlights invariant, essential features) relative to low-level construal (processing that highlights idiosyncratic, peripheral features) promotes self-control (Fujita & Carnevale, 2012). In the present work, we investigate to what extent people recognize the self-control benefits of high-level construal, and explore the consequences of this knowledge. Studies 1 and 2 provide initial evidence that individuals are aware that high-level relative to low-level construal promotes self-control in the dieting domain. Studies 3 and 4 find that individual differences in this knowledge predict self-control success outcomes (i.e., body mass index) among those who are motivated by dieting goals. Examining academics as a domain of self-control, Study 5 demonstrates that those with higher knowledge of construal level's impact on self-control earned higher end-of-semester grades to the extent that they were motivated to do well academically. Theoretical and practical implications of these findings are discussed. (PsycINFO Database Record

Research indicates that words activate high-level construal (processing that highlights central, goal-relevant features of events) whereas pictures activate low-level construal (processing that highlights idiosyncratic, peripheral features). We examine how these differences between words and pictures impact evaluative associations. Research has demonstrated that high-level relative to low-level construal promotes evaluative associations that enhance self-control, promoting associations that link smaller proximal rewards (temptations) with negativity and larger-distal rewards (goals) with positivity. Examining dieting as a self-control conflict, we find that words promote sensitivity to goal-relevant dimension of stimuli (i.e., health) while pictures promote sensitivity to temptation-relevant dimension of stimuli (i.e., taste) among those concerned with dieting in a single-category implicit association test (SC-IAT). An additional study finds that changing the presentation format of the IAT from pictures to words increases the tendency to associate temptations (i.e., desserts) with negativity among those concerned with dieting. Theoretical, methodological, and practical implications of these findings are discussed.

This chapter provides a conceptual analysis of the relationship between self-control and ego depletion. We first discuss self-control—the prioritization of larger distal over smaller proximal outcomes—and attempt to compare and contrast it to related terms such as self-regulation, executive function, delay of gratification, and inhibition. We then critically evaluate to what extent acts of self-control represent necessary and/or sufficient conditions to produce states of ego depletion—the apparent lack of willingness or ability to regulate one's thoughts, feelings, and behavior. This analysis leads to the surprising conclusion that acts of self-control are neither necessary nor sufficient to produce states of ego depletion. We discuss the implications of these conclusions for our understanding of self-control and highlight several new directions of research.

Many goals that people pursue are distal in that they cannot be attained in the here and now but rather must be achieved through action across varied social contexts over time. Self-control requires people to make decisions consistent with distal goals when tempted by more immediate rewards. Inspired by construal-level theory, we propose and review evidence that the way in which people subjectively represent, or construe, events systematically influences these decisions. We suggest that high-level construal (the use of cognitive abstraction to extract the essential and goal-relevant features common across a class of events), relative to low-level construal (the process of highlighting the incidental and idiosyncratic features that render a particular event unique), promotes self-control. We discuss implications for future research.

When making decisions, people sometimes deviate from normative standards. While such deviations may appear to be alarmingly common, examining individual differences may reveal a more nuanced picture. Specifically, the personality factor of need for cognition (i.e., the extent to which people engage in and enjoy effortful cognitive activities; Cacioppo & Petty, 1982) may moderate decision makers’ susceptibility to bias, as could personality factors associated with being a leader. As part of a large-scale assessment of high-level leaders, participants completed a battery of decision-making competence and personality scales. Leaders who scored higher on need for cognition performed better on two of four components of a decision-making competence measure: framing and honoring sunk costs. In addition, the leader sample performed better than published controls. Thus, both individual differences in need for cognition and leadership experience moderate susceptibility to decision biases. Implications for broader theories of individual differences and bias are discussed.
