Exemplar sequencing effects in incidental and intentional unsupervised category learning were investigated to illuminate how people form categories without an external teacher. Stimuli were perfectly separable into 2 categories based on 1 of 2 dimensions of variation. Sequencing of the first 20 training stimuli was manipulated. In the blocked condition, 10 Category A stimuli were followed by 10...

Spatial contextual cueing reflects an incidental form of learning that occurs when spatial distractor configurations are repeated in visual search displays. Recently, it was reported that the efficiency of contextual cueing can be modulated by reward. We replicated this behavioral finding and investigated its neural basis with fMRI. Reward value was associated with repeated displays in a learni...

Under incidental instructions, thirty-eight 2-year-olds were trained on a six-element deterministic sequence of spatial locations. Following training, subjects were informed of the presence of a sequence and asked to either reproduce or suppress the learned material. Children's production of the trained sequence was modulated by these instructions. When asked to suppress the trained sequence, t...

BACKGROUND The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. METHODS We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cyto...

Incidental learning is the learning of one stimulus feature while concentrating on another stimulus feature too. A little more specific connotation of incidental learning is that it involves the learning of formal aspects through a center of attention on semantic aspects. Incidental learning can occur in many modes inclusive of observations, communications with colleagues about tasks or project...

BACKGROUND AND OBJECTIVES The first laparoscopic appendectomy was performed over 25 years ago, and yet controversy still exists over the open method vs. the laparoscopic approach, and whether an incidental appendectomy is warranted. This study aimed to evaluate our experience in performing a laparoscopic incidental appendectomy and to address these issues. METHODS A total of 772 laparoscopic ...

According to the affect-as-information framework, consumers base judgments on their feelings. Disgust is associated with two kinds of appraisal: one in which the consumer avoids and distances him/herself immediately from the object concerned, and another in which the consumer is disgusted due to contamination and impurities within the environment. The first instance indicates that disgust can d...

OBJECTIVES The appendix may modulate colon microbiota and bowel inflammation. We investigated whether appendectomy alters colorectal cancer risk. METHODS We identified a cohort of 75,979 patients who underwent appendectomy between 1997 and 1999 based on the insurance claims of Taiwan. A comparison cohort of 303,640 persons without appendectomy was selected randomly, frequency matched by age, ...
