    SummerCool, a popular soft drinks manufacturer in Sparanthia, installed vending machines throughout the country and doubled its sales. The company took advantage of the fact that most consumers were used to buying its soft drinks from convenience stores and . Context Effects A given stimulus nat trigger radically different perceptions, partly because of our differing perceptual set, but also become of the immediate context. The brain can work backwards in time to allow a later stimulus to determine how we perceive an earlier one.

    finding in perceptual judgments is a "con-trast" effect, that is, judgment s of moderate stimuli in a series are found to be displaced away from extreme or distant stimuli. This effect has been found for judgments of physi-cal dimensions such as weight (e.g., Heintz, ; Sherif, Taub, & . T1 - Why do categories affect stimulus judgment? AU - Huttenlocher, Janellen.

    To elucidate the possible mechanistic role of amygdala dysfunction in the abnormal social attention of ASD, we undertook direct comparisons with SM. To test the roles of endogenously driven and exogenously driven attentional effects, we examined the effects of task (endogenous effects) and of stimuli (exogenous effects).Cited by: Task Effects. A novel aspect of the current study was the comparison afforded by using 2 tasks with very different processing demands. The Brightness task required a purely perceptual discrimination, which was maintained at a difficult level using an adaptive staircase by:

Contextual effects were strongest when similarities were assessed via a sorting task and were greatly attenuated when similarities were assessed via direct pairwise ratings of similarity. The contextual dependence of similarity measures provides one possible explanation for reported discrepancies in the dimensionality of the emotion by:   Task context effects were also present in the parietal memory network and impacted responses to both novel and familiar items.

We conclude by discussing implications of these findings with respect to current hypotheses regarding parietal contributions to memory by: 6. This chapter will discuss context effects and common biases that can affect sensory judgments. Context effects are conditions in which the judgment about a product, usually a scaled rating, will shift depending upon factors such as the other products that are evaluated in the same tasting by: 9.

There are a number of overlapping terms to describe change in perception with repeated exposure including acclimatization, adaptation, stimulus failure, fatigue as well as habituation (Helson.

Subjects were to judge as rapidly as possible whether pairs of geometric designs were the same or different on a given relevant dimension (size, shape, or color).

Response times varied depending on the number of values on nonrelevant dimensions shared by the comparison stimuli (stimulus similarity).

“Same” responses were facilitated by stimulus similarity, regardless of whether the stimuli Cited by: 2. stimulus context, loudness, and loudness judgments loudness comparison experiment, with the exception that the loudness matches for the Hz tones in Experi.

On the Interaction Between Stimulus Features and Context in the Perception causality that underlies the proliferation of context effects associated with perceived causal events. Here, the presence of make a judgment about that stimulus) the physical size of a stimulus interferes with judgments of numerical magnitude.

The authors tested a model of category effects on stimulus judgment. The model holds that the goal of stimulus judgment is to achieve high accuracy. For this reason, people place inexactly represented stimuli in the context of prior information, captured in categories, combining inexact fine-grain stimulus values with prior (category) Size: 2MB.

This theory deals with similarities between possible targets and nontargets in search, with local effects of similarity within a display, and with a variety of other findings holding across a range of different search Size: 2MB. The results show that measures of discriminability depend on stimulus range, and that measures of criterion placements change from trial to trial and depend on stimulus sequence.

There are persistent sequential effects in judgment tasks. For example, responses tend to be similar to the value of the just-prior stimulus. This is called assimilation. Emotional Semantic Congruency based on stimulus driven comparative judgements.

comparison task on stimulus pairs that were fully comparable in terms of their analog representation of intensity. These studies make it clear that estimates of intensity for a specific attribute of a sample are strongly influenced by stimulus context. In this paper, I will argue that a response context can have a similar influence on ratings of flavor components, and propose a model of judgment that attempts to characterize the observed response context Cited by: Armand V.

Cardello, in Context, Abstract. Context effects are interactions that occur when one stimulus is presented with another stimulus.

Such effects can be categorized as intrinsic (the contextual stimulus is integral to the target stimulus) or extrinsic (the contextual stimulus is external to the target stimulus).In foods and beverages, context effects can also be categorized by. A major advantage of the contrast model is its ability to explain and predict the influence of context and task effects on proximity judgments.

These findings suggest that context is most critical in influencing approachability judgements for negative emotions, most likely because there are more obvious potential negative ramifications associated with approaching an individual expressing a negative emotion (i.e., threat).Cited by: 5.

participants are shown a pair of similar pictures separated by a blank interval; the pictueres are identical except for a single aspect (e.g., a man is wearing a hat in one scene but not in the other); in these kinds of tasks, participants often find it hard to detect the change; this phenomenon is known as change.

Theoretical Approaches. Theoretical Approaches to Similarity. Similarity may seem to be an irreducible psychological primitive, like “red”, but various theorists have tried to show how it relates to other fundamental considerations. Let us assume, as do most writers, that stimulus objects are internally represented, and that similarity between objects comes from some sort of comparison.

refers to a person's level of negative thoughts regarding himself or herself. People high in neuroticism are insecure and experience emotional distress and may be perceived as unstable.

People low in neuroticism are more relaxed, have less emotional swings, and are .different people can form different mental images of the same physical stimulus.

When comparing people's speed at reasoning with abstract concepts (smarter- dumber), spatial concepts (above-below), and visual relationships (cleaner-dirtier), Knauff and Johnson found that ______ relationships had the slowest performance.

Priming effects in other paradigms also diminish with lag, but it is not clear why the effect of prior exposure on temporal perception disappeared after only a short inter-stimulus interval filled with approximately 20 intervening images, particularly since previous studies have demonstrated memory effects on temporal judgment using comparable delays, – although these studies used judgment tasks and stimulus types Cited by:
