Alzheimer's Disease (AD) can reduce the effects of emotional content on memory for studied pictures, but less is known about false memory. In healthy adults, emotionally arousing pictures can be more susceptible to false memory effects than neutral pictures, potentially because emotional pictures share conceptual similarities that cause memory confusions. We investigated these effects in AD pat...

Recent event-related brain potential studies revealed the selective processing of emotional and threatening pictures. Integrating the picture viewing and threat-of-shock paradigm, the present study examined the processing of emotional pictures while they were explicitly instructed to cue threat of real world danger (i.e. electric shocks). Toward this end, 60 pleasant, neutral and unpleasant IAP...

Thirty-six participants (18 female, 18 male) viewed affective pictures to investigate the coupling between emotional reactions and motivated behavior. Framed within the biphasic theory of emotion, the three systems approach was employed by collecting measures of subjective report, expressive physiology, and motivated behavior. Postural adjustments associated with viewing affective pictures were...

These days automatic image annotation is an important topic and several efforts are made to solve the semantic gap problem which is still an open issue. Also, Content Based Image Retrieval (CBIR) cannot solve this problem. One of the efficient and effective models for solving the semantic gap and visual recognition and retrieval is Bag of Feature (BoF) model which can quantize local visual feat...

While a 2-dimensional grid picture grammar may generate pictures (deened as subsets of the unit square) with arbitrarily small details, only a nite number of them can be made visible as raster images for any given raster. We present an algorithm based on bottom-up tree automata which computes the set of all raster images of the pictures generated by a given grid picture grammar.

rules In this experiment (Wallis, Anderson & Miller, 2001), illustrated in Figure 21, monkeys were trained to switch between two rules: Match and Non-match. Monkeys saw a sample picture followed by a delay and then a single test picture. For the match rule, the monkeys were given a reward if they released a lever when the pictures were the same, and held it if pictures were different. For the n...

Modulation of the startle reflex by sensory, attentional, and emotional processes was explored by presenting acoustic startle probes at various delays following picture onset. Within 500 ms of onset, blinks were first greatly facilitated and then inhibited, indicating prepulse facilitation and prepulse inhibition that did not vary with affect. Attention allocation to the picture continued acros...

A multimedia system for semi-automated image annotation, Show&Tell combines advances in speech recognition, natural language processing, and image understanding. Show&Tell differs from map annotation systems and has tremendous implications for situations where visual data must be coreferenced with text descriptions, such as medical image annotation and consumer photo annotation. S how&Tell take...
