Sub-millielectronvolt Line Widths in Polarized Low-Temperature Photoluminescence of 2D PbS Nanoplatelets.

Colloidal semiconductor nanocrystals are promising materials for classical and quantum light sources due to their efficient photoluminescence (PL) and versatile chemistry. While visible emitters are well-established, excellent (near-infrared) sources are still being pursued. We present the first comprehensive analysis of low-temperature PL from two-dimensional (2D) PbS nanoplatelets (NPLs).

On the interchangeability of presentation order for cause and effect: Experimental tests of cue and outcome-density effects.

Studies of cue-outcome contingency learning demonstrate outcome-density effects: participants typically overestimate contingencies when the outcome event is relatively frequent. Equivalent cue-density effects occur, although these have been examined less often. Few studies have simultaneously examined both event density effects or have manipulated the presentation order of the events, limiting knowledge of whether these phenomena share underlying principles.

How and Why the Choice of Success Criteria Can Impact Therapy Service Delivery: A Worked Example From a Psychological Therapy Service for Anxiety and Depression.

Background: Well-defined measures of therapeutic benefit are essential for evaluating therapies and services. However, there is no single gold standard for defining 'successful' outcomes. We therefore examined the potential impact of adopting different success criteria.

Testing the somatic marker hypothesis in decisions-from-experience with non-stationary outcome probabilities.

Introduction: The Somatic Marker Hypothesis (SMH) posits that in experience-based choice, people develop physiological reactions that mark options as either positive or negative. These somatic markers aid decision making because they differentiate between "good" and "bad" options during pre-choice deliberation.

Methods: We examined this proposed role for somatic states in two decision-from-experience tasks (each = 36) in which participants selected repeatedly with full feedback (i.

Examining Insensitivity to Probability in Evidence-Based Communication of Relative Risks: The Role of Affect and Communication Format.

Affect can influence judgments of event riskiness and use of risk-related information. Two studies (Ns: 85 and 100) examined the insensitivity-to-probability effect-where people discount probability information when scenarios are affect-rich-applying it to evidence-informed risk communication. We additionally investigated whether this effect is moderated by format, based on predictions from the evaluability and pattern-recognition literatures, suggesting that graphical formats may attenuate insensitivity to probability.
