The effects of aging on decision time were examined in a brightness discrimination experiment with young and older subjects (ages, 60-75 years). Results showed that older subjects were slightly slower than young subjects but just as accurate. Ratcliff's (1978) diffusion model was fit to the data, and it provided a good account of response times, their distributions, and response accuracy. There...

Background We assessed the prevalence of self-reported perceived discrimination in workplace after end treatment among breast cancer (BC) survivors and studied its association with social, health-related work-related factors. Methods used data from a French prospective cohort (CANcer TOxicities) including women diagnosed stage I–III BC. Our analysis included 2130 who were employed, <57 years...

BACKGROUND Stigma and discrimination may adversely affect the benefits of methadone maintenance treatment (MMT) for drug users, especially in disadvantaged settings. This study assessed stigma and discrimination against MMT patients in the mountainous and rural areas in Vietnam and explored their associated factors to inform implementation strategies. METHODS We interviewed 241 MMT patients i...

BACKGROUND Around the globe, discrimination has emerged as a social issue requiring serious consideration. From the perspective of public health, the impact of discrimination on the health of affected individuals is a subject of great importance. On the other hand, subjective well-being is a key indicator of an individual's physical, mental, and social health. The present study aims to analyze ...

A method for managing agile sensors to optimize detection and classiication based on discrimination gain is presented. Expected discrimination gain is used to determine threshold settings and search order for a collection of discrete detection cells. This is applied in a low signal-to-noise environment where target-containing cells must be sampled many times before a target can be detected or c...

A method for managing agile sensors to optimize detection and classi cation based on discrimination gain is presented. Expected discrimination gain is used to determine threshold settings and search order for a collection of discrete detection cells. This is applied in a low signal-tonoise environment where target-containing cells must be sampled many times before a target can be detected or cl...

Saccade curvature represents a sensitive measure of oculomotor inhibition with saccades curving away from covertly attended locations. Here we investigated whether and how saccade curvature depends on movement preparation time when a perceptual task is performed during or before saccade preparation. Participants performed a dual-task including a visual discrimination task at a cued location and...

We examined the effects of emotional stimuli on right and left hemisphere detection performance in a hemifield visual discrimination task. A group of 18 healthy subjects were asked to discriminate between upright and inverted triangles (target). Targets were randomly presented in the left or right visual hemifield (150 ms target duration). A brief emotional picture (pleasant or unpleasant; 150 ...

Previous evidence that repetition of an item in a list enhances that item's recency relative to other items has been interpreted as favoring a memory strength theory of recency discrimination. However, serious doubt has been cast upon the validity of the strength theory by experiments such as that of Hintzman and Block, which instead favor a multitrace representation for repetitions of an item....

Visual spatial attention can be exogenously captured by a salient stimulus or can be endogenously allocated by voluntary effort. Whether these two attention modes serve distinctive functions is debated, but for processing of single targets the literature suggests superiority of exogenous attention (it is faster acting and serves more functions). We report that endogenous attention uniquely cont...
